Opis:

This paper presents a proposal for structuring real-time programs in a way that improves their reliability. Basically, it consists of five constructs that have been designed after the model of classical "structured programming", together with a generalized way of dealing with resources. After some considerations about reliability these constructs are presented and explained. Then, a test implementation for two different programming languages and operating systems is briefly described. Finally, some pieces of code give an impression of the character of the method.

Opis:

Modern robotics brings up a variety of new challenges. Industrial-only times are gone forever. Nowadays, by performing many diversified services, robots turned out to be a part of our everyday life. There is no doubt that they should be able to interact with this new miscellaneous environment seamlessly. Along with the number of requirements, the importance of software increases. While gaining more autonomy, besides standard motion control, a wide range of cogntive tasks has to be executed simultaneously. It is quite obvious that complex systems with a lot of independent modules and many functions to perform need flexible and reliable sofware solutions. This article takes a Real-Time Operating System as an answer to the problems of the new generation robotics.By comparing selected features, it provides an evaluation of the most popular commercial and non-commercial solutions. Paper describes the key characteristics that should be taken into consideration during the design process and presents several examples of their successful robotic applications, including our own choices for decentralized controllers.

Opis:

The RTN measurements in Poland date back to 2006, when the Małopolska System for Precision Positioning (MSPP) was started up. In 2008, the nationwide ASG-EUPOS system was put in operation in Poland. The paper presents the results of the test measurements aimed at evaluating the accuracy of position determination of points, based on the MSPP. The GPS static measurements, RTN measurements, tachymetric measurements and precision levelling were performed on 24 test points stabilised in the distances of approx. 12 km, 21 km and 34 km from the KRAW station located centrally in the MSPP. During the test measurements ca. 3000 positions of points were determined altogether, using the following mountpoints: RTCM_FKP, RTCM_23VRS, RTK3.0 (RTCM 3.0 VRS) and KRAW_RTCM30. While analysing the averaged results of the measurements of the test points, it can be concluded that the information published on the MSPP website (regarding the point position accuracy of at least 3 cm for situation and 5 cm for height) is reflected in the measurement results. Taking into consideration each of the solutions individually, the values were indeed exceeded for the horizontal coordinates – 3.6% and for the height 5.6%, except for the Single Baseline solution, in which the height differences were only rarely below 5 cm.
W Polsce historia pomiarów RTN sięga praktycznie roku 2006, kiedy to uruchomiono regionalny Małopolski System Pozycjonowania Precyzyjnego (MSPP). W 2008 r. oddano do użytku ogólnopolski system ASG-EUPOS. W pracy przedstawiono wyniki pomiarów testowych, mających na celu ocenę dokładności wyznaczania pozycji punktów w oparciu o MSPP. Pomiary statyczne GPS, pomiary RTN, pomiary tachymetryczne oraz niwelację precyzyjną wykonano na 24 punktach testowych zastabilizowanych w odległościach ok. 12 km, 21 km i 34 km od stacji KRAW zlokalizowanej centralnie w MSPP. W pomiarach testowych wyznaczono łącznie ok. 3000 pozycji punktów, korzystając z mountpointów: RTCM_FKP, RTCM_23VRS, RTK3.0 (RTCM 3.0 VRS) oraz KRAWRTCM30. Analizując wyniki pomiarów punktów testowych zgeneralizowane do wartości średnich, należy stwierdzić, że podawane na stronie MSPP informacje o dokładności wyznaczenia pozycji punktu nie gorszej niż 3 cm sytuacyjnie i 5 cm wysokościowo znalazły potwierdzenie w wynikach pomiarów. Biorąc pod uwagę każde z rozwiązań indywidualnie, należy stwierdzić, iż wartości te bywały jednak przekraczane w przypadku współrzędnych sytuacyjnych 3,6% oraz wysokości 5,6%, z wyłączeniem rozwiązania Single Baseline, w którym różnice wysokości tylko sporadycznie były mniejsze od 5 cm.

Opis:

The Third Generation Partnership Project (3GPP) has developed a new cellular standard based packet switching allowing high data rate, 100 Mbps in Downlink and 50 Mbps in Uplink, and having the flexibility to be used in different bandwidths ranging from 1.4 MHz up to 20 MHz, this standard is termed LTE (Long Term Evolution). Radio Resource Management (RRM) procedure is one of the key design roles for improving LTE system performance, Packet scheduling is one of the RRM mechanisms and it is responsible for radio resources allocation, However, Scheduling algorithms are not defined in 3GPP specifications. Therefore, it gets a track interests for researchers. In this paper we proposed a new LTE scheduling algorithm and we compared its performances with other well known algorithms such as Proportional Fairness (PF), Modified Largest Weighted Delay First (MLWDF), and Exponential Proportional Fairness (EXPPF) in downlink direction. The simulation results shows that the proposed scheduler satisfies the quality of service (QoS) requirements of the real-time traffic in terms of packet loss ratio (PLR), average throughput and packet delay. This paper also discusses the key issues of scheduling algorithms to be considered in future traffic requirements.

Due to the heavily software-centric nature of modern reactive and time-critical systems, there is an increasing demand for efficient development of high quality Real-Time Software-Intensive Control systems (RSIC). The study discussed in this paper is focused on the creation of international curriculum framework centred on RSIC - this important aspect of computer-system-control-software engineering education. The study explores the mechanism for involving students from multilingual, geographically separated institutions in a coordinated educational experience. It exposes them to the problems, methods, solution techniques, infrastructure, technologies, regulatory issues, and tools in the domain of dependable real-time, safety-critical, software-intensive control systems. The ultimate objective is the creation of a model RSIC curriculum, which can be used by engineering schools both in the USA and the EU.

W artykule przedstawiono przegląd analizatorów DNA wykorzystujących technikę real-time PCR i lab-chipy. Zaprezentowano opis opracowanej metodologii i instrumentarium do detekcji fluorescencji z wykorzystaniem miniaturowych komponentów optoelektronicznych i "inteligentnego" oprogramowania analizującego. Przedstawiono dwa przykłady miniaturowych analizatorów real-time PCR/DNA opracowanych w ramach projektów europejskich i krajowych wykorzystujących lab-chipy i nowatorską metodę detekcji fluorymetrycznej.
The paper presents a novel miniaturized optical instrumentation for fluorescence excitation and detection for miniaturized real-time PCR analyzers using lab-on-a-chip (LOC) devices. Application of miniaturized semiconductor laser to fluorescence excitation, CCD-minicamera as fluorescence photodetector and specialized software for optical signal conditioning led to development of low-cost and highly sensitive optical instrumentation. To carry out full characterization of the optical instrumentation, miniaturized thermocycler co-working with LOC was built. The optical instrumentation was tested with three LOC made of different materials and technologies, giving proper detection of fluorescence signals during real-time PCR. Finally, two miniaturized devices for real-time PCR detection and identification of DNA and utilizing described here novel optical instrumentation were briefly described. The scheme and technical realization of the novel instrumentation in laboratory version is shown in Fig. 4. The detection limit of DNA was about 0,1 ng/ml (Fig. 5). It was also found that the optical instrumentation co-works with different constructions of lab-on-a-chips for DNA real-time PCR amplification (Fig. 6). The developed optical instrumentation was successfully applied to two miniaturized devices for DNA detection and identification by real-time PCR. Technical realizations of the devices and views of the lab-on-a-chips are shown in Figs. 7 and 9. In both cases, proper detection of fluorescence signals generated during real-time PCR of Campylobacter j. DNA (Fig. 8) or complementary DNA (Fig. 10) were observed. It confirmed high sensitivity of the developed optical instrumentation.

Opis:

The crime rates in Mexico have been increasing in recent years; every day, there are reports on social media and in the news where assaults and verbal aggression by criminals can be seen. Public transportation units suffer from violence that authorities have not been able to reduce despite their efforts. This is why we have developed a fuzzy logic model that can adapt to almost any scenario thanks to the dynamism that we have implemented in each of its stages. We have obtained promising results that we believe will be of great help to the authorities for detecting the exact moment in which verbal aggression that is typical of a violent assault is happening in real time. This is a tool to help the authorities, not a substitution; we are simply making use of the latest technologies that are available to us. The goal of this paper is to provide a novel method for Mexican authorities in Mexico City in order to help the actual surveillance systems make faster decisions about whether violent assaults are happening or not.

To develop a sensitive, specific, and rapid approach for the detection Getah virus (GETV), a set of primers targeting the conserved region of the E1 gene was created. The TaqMan-based real-time PCR method for GETV detection was developed by optimizing the reaction conditions. The method demonstrated excellent specificity, and amplification did not occur with the causative agents of all prevalent swine viral infections (CSFV, PRRSV, PRV, PEDV, PTV, and JEV), except GETV. Additionally, upon assessing the sensitivity of the method, the minimum detection limit for GETV was found to be 5.94 copies/μL, which is 10 times higher than that of the traditional PCR approach. Further, the intra- and inter-assay variation coefficients were less than 1%, demonstrating good repeatability. Moreover, GETV was found in 10 of the 20 field serum samples using real-time PCR but only in three of the samples using traditional PCR. Consequently, the first GETV TaqMan-based real-time PCR approach based on the E1 gene was developed for GETV pathogenic diagnoses, and this exhibited high specificity, sensitivity, and repeatability. This assay is practical for the pathogenic diagnosis and epidemiology of GETV.

Opis:

The challenge to be addressed by this paper is to extend the common machine tool thermal compensation models considering only internal heat sources to include the effects of the cutting process. Although real-time software compensations of thermal errors exist, the majority of these models only presume machine tools under load-free rotation of the main spindle without any reference to rough machining. The machining process is completely neglected in spite of the fact that it represents a significant heat source and causes workpiece inaccuracy. This paper presents a real-time compensation of three-axis vertical milling centre thermal errors including the cutting process effect. The simulation is based on dynamic modelling using transfer functions. The model was implemented into a standard CNC controller of a three-axis vertical milling centre to compensate for thermal errors in real time. The inputs of the compensation algorithm are the spindle rotational speed, the 5 temperatures of the machine structure and spindle power. A reduction of thermal errors achieved by using the new approximation TF model including cutting process impact is up to 79% for steel cutting tests with different cutting conditions.

The study aim was evaluation of the usefulness of several thermostable DNA polymerases in real time PCR conducted in the presence of the heme. Our study had the advantage of testing several different polymerases, one of which proved to be the least sensitive to heme activity. We also found that there is no need of supplementing the reaction mixture with protective substances like BSA. Selection of the appropriate polymerase can increase the efficiency of the PCR reaction which is very important for diagnosis of sepsis and for other analyses performed on DNA template isolated from the blood.

Opis:

A potentiometric procedure for cysteine thiol group concentration monitoring in media generating free radicals was developed using a thiol specific silver-mercury electrode. Electrolytic deposition of mercury on a silver wire and treatment with 20 mM cysteine in 0.5 M NaOH were used to produce the electrode. A silver-chloride electrode in saturated KCl was the reference. A glass capillary with 1 M KNO3 in 1% agarose gel was the liquid junction. The electrode responded to cysteine concentration in the range from 0.01 to 20 mM yielding a perfect linear relationship for the dependence of log [cysteine] versus electrode potential [mV], with b0 (constant) = -373.43 [mV], b1 (slope) = -53.82 and correlation coefficient r2 = 0.97. The electrode potential change per decade of cysteine concentration was 57 mV. The minimal measurable signal response was at a cysteine concentration of 0.01 mM. The signal CV amounted to 4-6% for cysteine concentrations of 0.01 to 0.05 mM and to less than 1% for cysteine concentrations of 0.5 to 20 mM. The response time ranged from about 100 s for cysteine concentrations of 0.01 to 0.1 mM to 30 s at higher cysteine concentrations. The standard curve reproducibility was the best at cysteine concentrations from 0.1 to 20 mM. In a reaction medium containing cysteine and copper(II)-histidine complex ([His-Cu]2+) solution in 55 mM phosphate buffer pH 7.4 the electrode adequately responded to changes in cysteine concentration. Beside cysteine, the silver-mercury electrode responded also to thiol groups of homocysteine and glutathione, however, the Nernst equation slope was about half of that for cysteine.

Reservoir inflow forecasting with high reliability plays an important role in the operation and management of the reservoir for power generation, irrigation, flood prevention as well as ensuring the safety of the dam. However, the level of forecast accuracy is limited, since its performance depends on rainfall forecasting and hydrological model. In order to increase the efficiency of forecasting, this study introduces the inflow forecasting method that integrates the real-time updating techniques with continuous optimization method of MIKE NAM model to specify the appropriate parameter set for forecasting time. The proposed forecasting method was tested for the Ho Ho reservoir, the area facing the scarcity of historical data for model calibration and verification. The analysis of the forecasting results for Ho Ho reservoir using transferred parameters from the stable calibrated parameter values at Hoa Duyet station (downstream of Ho Ho reservoir) and the results obtained using the adapted parameters by the proposed method shows that the adapted parameter values provides a more reliable forecast, which will better serve the decision making.

Multi-MeV proton and light ion beams had been produced using the 300 ps, kJ-class iodine laser, operating at Prague Asterix Laser System (PALS) Centre in Prague. The target material had been chosen in such a way so as to increase the proton beam current density (approaching 0.1 A/cm2 at the distance of 1 m from the source). The real-time ion detection was performed by means of a standard flat and ring ion collectors (IC) in the time-of-flight (TOF) configuration. The ICs had been shielded with aluminum foils of various thickness, in order to cut the long photo-peak contribution that is usually overlapping with the ultrafast particle signal, and to analyze mainly the laser-accelerated proton beam. The processing of the obtained experimental IC data is described in some detail, including the deconvolution of TOF signals, evaluation of the UV/soft-X-ray photo-peak absorption, and ion transmission calculations for different metallic filters.

Structural motifs found in naturally occurring compounds are frequently used by researchers to develop novel synthetic drug candidates. Some of these new agents are hybrid molecules which are designed through a concept of combining more than one functional element. In this report, anticancer activity of new synthetic molecular hybrids, substituted 3-diethoxyphosphorylnaphtho[2,3-b]furan-4,9-diones and 3-diethoxyphosphorylbenzo[f]indole-4,9-diones, which integrate natural 1,4-naphtalenedione scaffold, present in several anticancer agents, with pharmacophoric phosphonate moiety, were tested against hepatocellular cell line HepG2. Cytotoxicity was examined using MTT assay. Two most potent compounds, furandione 8a and benzoindoldione 12a, which reduced the number of viable HepG2 cells with the IC50 values of 4.13 µM and 5.9 µM, respectively, were selected for further research. These compounds decreased the mRNA expression levels of several genes: Bcl-2, angiogenic vascular endothelial growth factor (VEGF), c-Fos, caspase-8 and increased the expression of Bax, caspase-3 and -9, c-Jun, p21, p53, as determined by quantitative real-time PCR. The ability of these compounds to induce apoptosis and DNA damage was studied by flow cytometry. The obtained data showed that the new compounds inhibited cell viability by increasing apoptosis and decreasing angiogenesis. Compound 8a was a much stronger apoptosis inducer as compared with 12a and strongly activated the intrinsic pathway of apoptosis, associated with the loss of mitochondrial membrane potential and changes in Bax/Bcl-2 ratio. These findings show that the synthetic hybrids combining 1,4-naphthalenedione system and phosphonic acid moiety display potential to be further explored in the development of new anticancer agents.

Opis:

Fungi of the Alternaria genus are mostly associated with allergic diseases. However, with a growing number of immunocompromised patients, these fungi, with A. alternata being the most prevalent one, are increasingly recognized as etiological agents of infections (phaeohyphomycoses) in humans. Nowadays, identification of Alternaria spp. requires their pure culture and is solely based on morphological criteria. Clinically, Alternaria infections may be indistinguishable from other fungal diseases. Therefore, a diagnostic result is often delayed or even not achieved at all. In this paper we present easy to perform and interpret PCR and real-time PCR assays enabling detection of A. alternata species. On the basis of alignment of β-tubulin gene sequences, A. alternata-specific primers were designed. DNA from fungal isolates, extracted in a two-step procedure, were used in PCR and real-time PCR assays followed by electrophoresis or melting temperature analysis, respectively. The assays specificity was confirmed, since positive results were obtained for all A. alternata isolates, and no positive results were obtained neither for other molds, dermatophytes, yeast-like fungi, nor human DNA. The assays developed here enable fast and unambiguous identification of A. alternata pathogens.

Poprawne znakowanie mięsa pozwalające konsumentowi świadomie wybrać jego rodzaj jest istotne z wielu względów – od zdrowotnych po religijne. Ponadto ze względu na różnice cen i dostępność surow- ców mięsnych pochodzących z różnych gatunków zwierząt zdarzają się przypadki fałszowania żywności. Składniki wyrobów mięsnych są wykorzystywane nieadekwatnie do informacji podanej na etykiecie. Niezgodności dotyczą zarówno użytych surowców, jak i ich zawartości w produkcie mięsnym. Mięso o wysokiej jakości zastępuje się tańszym lub jego zawartość jest mniejsza od deklarowanej. Choć obowią- zują przepisy dotyczące znakowania przetworzonych produktów mięsnych, zdarzają się przypadki wystę- powania na rynku wyrobów mięsnych zafałszowanych. W niniejszych badaniach podjęto się opracowania procedury weryfikacji autentyczności wyrobów z mięsa strusia czerwonoskórego (Struthio camelus). Zaproponowano metodę wykorzystującą technikę real-time PCR. Jak wykazano, DNA jest wystarczająco stabilne, aby wytrzymać zróżnicowaną obróbkę technologiczną. Badania prowadzono z użyciem wyrobów modelowych oraz wyrobów mięsnych (kiełbas, steków, mięsa gulaszowego) zakupionych w handlu deta- licznym. Próbki były analizowane pod względem obecności niedeklarowanych gatunków mięsa (wie- przowiny, wołowiny, mięsa z kurcząt, kaczek i gęsi) z wykorzystaniem gatunkowo specyficznych starte- rów. Na podstawie otrzymanych wyników wykazano, że opracowana procedura identyfikacji mięsa strusia może być z powodzeniem stosowana w rutynowych kontrolach, zarówno jakościowych (wykluczenie danego gatunku), jak i ilościowych (oznaczenie udziału mięsa strusia) w tego typu żywności. Wykazano ponadto, że w wyrobach przetworzonych może występować problem niedeklarowanego dodatku mięsa innego niż wskazane na etykiecie.

Opis:

This paper presents the application of a task scheduling algorithm called Fan based on artificial intelligence technique such as genetic algorithms for the problem of finding minima in objective functions, where equations are predefined to measure the return on investment. This work combines the methodologies of population exploration and exploitation. Results with good aptitudes are obtained until a better learning based on non-termination conditions is found, until the individual provides a better predisposi¬tion, adhering to the established constraints, exhausting all possible options and satisfying the stopping condition. A real-time task planning algorithm was applied based on consensus techniques. A software tool was developed, and the scheduler called FAN was adapted that contemplates the execution of periodic, aperiodic, and sporadic tasks focused on controlled environments, considering that strict time restrictions are met. In the first phase of the work, it is shown how convergence precipitates to an evolution. This is done in a few iterations. In the second stage, exploitation was improved, giving the algorithm a better performance in convergence and feasibility. As a result, a population was used and iterations were applied with a fan algorithm and better predisposition was obtained, which occurs in asynchronous processes while scheduling in real time.

Opis:

Neuroblastoma is one of the most common paediatric cancers, described as unpredictable due to diverse patterns of behaviour. WWOX is a tumour suppressor gene whose expression is reduced in many tumour types. Loss of its expression was shown to correlate with more aggressive disease stage and mortality rate. The aim of this study was to investigate the role of the WWOX tumour suppressor gene in neuroblastoma formation. We performed real-time RT-PCR to analyse levels of WWOX expression in 22 neuroblastic tumour samples in correlation with genes involved in cell cycle regulation (CCNE1, CCND1), proliferation (MKI67), apoptosis (BCL2, BIRC5, BAX) and signal transduction (EGFR, ERBB4). We also evaluated two potential mechanisms - promoter methylation (MethylScreen method) and loss of heterozygosity (LOH) status, which could be connected with regulation of WWOX gene expression. We found a positive correlation between WWOX gene and BCL2 and HER4 JM-a and negative with cyclin D1 and E1. Our observations are consistent with previous findings and emphasise the role of WWOX in cell cycle and apoptosis regulation. Moreover, strong positive association with HER4 JM-a in this tumour type may indicate a role for WWOX in neuroblastoma cell differentiation. The presented results indicate that LOH in locus D16S3096 (located in intron 8) may be involved in the regulation of WWOX mRNAexpression. However, no association between methylation status of WWOX promoter and its expression was observed.

Dermatophytes are keratinophilic molds that infect human hair, nails and skin. Diagnosis of dermatophytosis is based on morphological, serological and biochemical features. However, identification is difficult and laborious due to similarities between microorganisms. Thus, there is considerable interest to develop mycological diagnostic procedures based on molecular biology methods. In this study, fast, two-step DNA extraction method and real-time PCR was used for detection of dermatophytes DNA using pan-dermatophyte primers and identification of Trichophyton rubrum from pure cultures. The applied method allowed correct detection of all dermatophytes and correct identification of Trichophyton rubrum in less than 2 hours.

Opis:

Background: With an increase of the number of features in a vehicle, the computational requirements also increase, and vehicles may contain up to 100 Electronic Control Units (ECUs) to accommodate these requirements. For cost-effectiveness reasons, amongst others, it is considered desirable to limit the growth of, or preferably reduce, the number of ECUs. To that end, mixed criticality is a promising approach that received a lot of attention in the literature, primarily from a theoretical perspective. Aim: In this paper, we address mixed criticality from a practical perspective. Our prime goal is to extend an OSEK-compliant real-time operating system (RTOS) with mixed criticality support, enabling such support in the automotive domain. In addition, we aim at a system (i) supporting more than two criticality levels; (ii) with minimal overhead upon an increase of the so-called criticality level indicator of the system; (iii) requiring no changes to an underlying operating system; and (iv) featuring further extensions, such as hierarchical scheduling and multi-core. Method: We used the so-called adaptive mixed criticality (AMC) scheme as a starting point for mixed criticality. We extended that scheme from two to more than two criticality levels (satisfying (i)) and complemented it with specified behavior for criticality level changes. We baptized our extended scheme AMC*. Rather than selecting a specific OSEK-compliant RTOS, we selected ExSched, an operating system independent external CPU scheduler framework for real-time systems, which requires no modifications to the original operating system source code (satisfying (iii)) and features further extensions (satisfying (iv))). Results: Although we managed to build a functional prototype of our system, our experience with ExSched made us decide to rebuild the system with a specific OSEK-compliant RTOS, being µC/OS-II. We also briefly report upon our experience with AMC* and suggest directions for improvements. Conclusions: Compared to extending ExSched with AMC*, extending µC/OS-II turned out to be straightforward. Although we now have a basic system operational and available for experimentation, enhancements of the AMC*-scheme are considered desirable before exploitation in a vehicle.

Opis:

The aim of this study is to design and implement a system that detect driver sleepiness and warn driver in real-time using image processing and machine learning techniques.Viola-Jones detector was used for segmenting face and eye images from the camera-acquired driver video. Left and right eye images were combined into a single image. Thus, an image was obtained in minimum dimensions containing both eyes. Features of these images were extracted by using Gabor filters. These features were used to classifying images for open and closed eyes. Five machine learning algorithms were evaluated with four volunteer’s eye image data set obtained from driving simulator. Nearest neighbor IBk algorithm has highest accuracy by 94.76% while J48 decision tree algorithm has fastest classification speed with 91.98% accuracy. J48 decision tree algorithm was recommended for real time running. PERCLOS the ratio of number of closed eyes in one minute period and CLOSDUR the duration of closed eyes were calculated. The driver is warned with the first level alarm when the PERCLOS value is 0.15 or above, and with second level alarm when it is 0.3 or above. In addition, when it is detected that the eyes remain closed for two seconds, the driver is also warned by the second level alarm regardless of the PERCLOS value. Designed and developed real-time application can able to detect driver sleepiness with 24 FPS image processing speed and 90% real time classification accuracy. Driver sleepiness were able to detect and driver was warned successfully in real time when sleepiness level of driver is achieved the defined threshold values.

Sequential pattern mining is an extensively studied method for data mining. One of new and less documented approaches is estimation of statistical characteristics of sequence for creating model sequences, that can be used to speed up the process of sequence mining. This paper proposes extensive modifications to one of such algorithms, ProMFS (probabilistic algorithm for mining frequent sequences), which notably increases algorithm's processing speed by a significant reduction of its computational complexity. A new version of algorithm is evaluated for real-life and artificial data sets and proven to be useful in real-time applications and problems.

Opis:

In order to guarantee the accuracy of turntable angle measurement, a real-time compensation method for turntable positioning precision based on harmonic analysis is proposed in this paper. Firstly, the principle and feasibility of the real-time compensation method are analysed, and a detailed description of harmonic compensation is provided herein. Secondly, we analyse the relationships between the surface number of the polygon with the compensation order of the harmonic function and its corresponding compensation accuracy. The effects of the iterations number and the data width on calculation accuracy in the coordinate rotation digital computer (CORDIC) algorithm are analysed and the quantization models of the approximation error and rounding error of the CORDIC algorithm are established. Then, the calculation of the harmonic error function and real-time compensation processes are implemented on a field programmable gate array (FPGA) chip. The resource occupation and time delay of the phase angle calculation and the harmonic component calculation are discussed separately. Finally, the validity of the harmonic compensation method is proven through comparing the compensation effect with that of linear interpolation and the polynomial compensation method. The influences of the compensation order, the iterations number and the data width on the compensation results are demonstrated by simulation. A test platform with a laboratory-made FPGA circuit is built to evaluate the effect of real-time compensation with the harmonic function and the positioning error compensation can be performed within 760 ns. The results confirmed the effectiveness of the harmonic compensation method, revealing an improvement of the positioning precision from 54.21ʹʹ to 1.63ʹʹ, equivalent to 96.99% reduction in positioning error.

Aleja Mickiewicza 24/28, 30-059 Kraków, Poland Abstract: The objective of this paper is to present the concept of a novel system, known as HydroProg, that aims to issue flood warnings in real time on the basis of numerous hydrological predictions computed using various models. The core infrastructure of the system is hosted by the University of Wrocław, Poland. A newly-established computational centre provides in real time, courtesy of the project Partners, various modelling groups, referred to as “project Participants”, with hydrometeorological data. The project Participants, having downloaded the most recent observations, are requested to run their hydrologic models on their machines and to provide the HydroProg system with the most up-to-date prediction of riverflow. The system gathers individual forecasts derived by the Participants and processes them in order to compute the ensemble prediction based on multiple models, following the approach known as multimodelling. The system is implemented in R and, in order to attain the above-mentioned functionality, is equipped with numerous scripts that manipulate PostgreSQL- and MySQL-managed databases and control the data quality as well as the data processing flow. As a result, the Participants are provided with multivariate hydrometeorological time series with sparse outliers and without missing values, and they may use these data to run their models. The first strategic project Partner is the County Office in Kłodzko, Poland, owner of the Local System for Flood Monitoring in Kłodzko County. The experimental implementation of the HydroProg system in the Nysa Kłodzka river basin has been completed, and six hydrologic models are run by scientists or research groups from the University of Wrocław, Poland, who act as Participants. Herein, we shows a single prediction exercise which serves as an example of the HydroProg performance.

Teamwork has distinct pedagogic advantages and is also an important transferable skill and the dominant mode of work graduates encounter in the workplace. However, students rarely become proficient in teamwork skills during their education. The goal was to test strategies to improve teamwork skills in a course on Ores deposits, MSc Earth Science, Uppsala University. A focus on teamwork was established by presenting the collaborative practicals as a series of linked opportunities to work together, get feedback on the teamwork process and reflect on and evaluate the teamwork. During the collaborative PBL sessions sociograms were used to provide feedback. Criteria based evaluation was also used to evaluate task oriented and interpersonal skills. Sociograms and criteria based evaluation promoted behavioural changes that improved teamwork interactions.

Opis:

During sports training, providing athletes with real-time feedback that is based on the automatic analysis of motion is both useful and challenging. In this work, a novel system that is based on mixed reality is proposed and verified. The system allows for immersive and real-time visual feedback in fencing training. Novel methods have been introduced for 3D blade tracking from a single RGB camera, creating weapon-action models by recording the actions of a coach and evaluating the trainee’s performance against these models. Augmented reality glasses with see-through displays are employed, and a method for coordinate mapping between the virtual and real environments is proposed; this will allow for the provision of real-time visual cues and feedback by overlaying virtual trajectories on the real-world view. The system has been verified experimentally in fencing bladework training (with the supervision of a fencing coach). The results indicate that the proposed system allows novice fencers to perform their exercises more precisely.

Opis:

A scheme for real-time optical demultiplexing is proposed by utilizing the time-broadened and linearly chirped pulses instead of the conventional mode-locked pulses. The copies of the optical-time-division-multiplexed signal are acquired through a dual-pump parametric gate and used as the parametric multicast block. Simulation results show that the demultiplexing from 160 Gb/s down to sixteen 10 Gb/s tributaries can be achieved only by using a sampling source of 10 GHz. The proposed scheme can effectively reduce the complexity of parallel processing, and find important applications in the high-speed all-optical signal processing.

Opis:

In thise paper a very simple method of the visual information interpretation for recognition and navigation purposes is presented and discussed. The proposed method consists of six steps: image acquisition, edge detection, fast edge vectorization using a high number of short preliminary vectors, aggregation of the preliminary vectors into the form of final vectors. The next stages of the visualthe visual information interpretation for recognition and navigation purposes will be description of the objects’ shapes by means of the final vectors, object recognition and/or robot navigation on the base of comparison between actual shape description and templates memorized during the programming/training process, but they are not discussed in this paper. The main advantage of the proposed method is a simple and time-effective algorithm, which can be performed in real time also by a simple and cheap processor, working as a “brain” of the considered robot.

Opis:

In cases when the navigational space of the manoeuvre performed by the ship is severely limited, the procedures making use of the rudder blade, propeller screw, and thrusters are very complicated. Such situations take place when the ship manoeuvres inside the harbour area and in those cases the structure of the control system is very complex. The article describes the algorithm of multivariable control of ship motion over the water surface, which makes use of the state vector consisting of 6 variables. Three of them, which are the position coordinates (x, y) measured by the DGPS system and the ship heading y measured by gyro-compass, were obtained experimentally. The three remaining variables, which are the velocities in surge u, sway v, and yaw r directions, were estimated by Kalman filter, Kalman- Bucy filter and extended Kalman filter, respectively. The control algorithms making use of these observers were examined using the training ship „Blue Lady” which was navigated on the lake Silm in Ilawa/Kamionka in the Ship Handling Research and Training Centre owned by the Foundation for Safety of Navigation and Environment Protection. The experimental results obtained using control systems with three observers were finally compared between each other.

Opis:

Based on the payments and settlement system, the influence of the topology of capital flow networks on the extra short-term liquidity demand is investigated. Through modelling the circulating mechanism of liquidity in a network, its different influencing factors are analysed. The factors relating to the strength of nodes and leakage of liquidity that influences the liquidity demands of real-time settlements are studied from the perspective of both the system and members, using different simulation methods. The results show that strength will lead the member’s liquidity demand to increase but the strength distribution will lead the system’s liquidity demand to decrease, in cases with no leakage effect or unchanged leakage effect. The liquidity demand of the entire system is positive compared to the amount of leakage effect but uncorrelated to the distribution of the leakage effect among members, if the effect of strength distribution is unchanged. If the effects of strength, strength distribution and leakage are changed together, the latter is the dominant factor that influences the liquidity demand of both system and members. The above findings are useful for the management and supervision of short-term liquidity demand in complex financial systems, and for liquidity risk management and liquidity rescue policymaking.

Opis:

Rat robots have great potential in rescue and search tasks because of their excellent motion ability. However, most of the current rat-robot systems relay on human guidance due to variable voluntary motor behaviour of rats, which limits their application. In this study, we developed a real-time system to detect a rat robot’s transient motion states, as the prerequisite for further study of automatic navigation. We built the detection model by using a wearable inertial sensor to capture acceleration and angular velocity data during the control of a rat robot. Various machine learning algorithms, including Decision Trees, Random Forests, Logistic Regression, and Support Vector Machines, were employed to perform the classification of motion states. This detection system was tested in manual navigation experiments, with detection accuracy achieving 96.70%. The sequence of transient motion states could be further used as a promising reference for offline behaviour analysis.

The system is based on a measurement station that has the shape of a floating buoy which is supposed to be at anchor on the reservoir. Wireless data transmission problems that were encountered during the development of the buoy, modeling a radio link, and measurements of actual signal strength on the reservoir are discussed. A mathematical approach to procedures of early situation assessment was conducted, and specialized procedures were designed for measurement stations of the system. It is also discussed how such computations can improve a qualitative assessment of system performance in terms of real-time messaging.

Opis:

Grain samples of spring barley from the 2009 and 2010 harvest were analysed for the content of DNA of Fusarium species and Fusarium toxins (type B trichothecenes). Samples originated from different fields in Radzików, Central Poland. Qualitative and quantitative determination of Fusarium species in the grain was performed using a real-time PCR. Fusarium toxins in the grain were analysed by gas chromatography. Seven Fusarium species were detected in barley grain. The dominating species were F. avenaceum, F. graminearum and F. poae. The presence of F. culmorum, F. langsethiae, F. sporotrichioides and F. tricinctum was also detected. The concentration of trichothecene toxins in grain (deoxynivalenol, nivalenol) was low. The highest correlation coefficient of deoxynivalenol vs. Fusarium DNA was found for F. graminearum. Regarding nivalenol, the highest correlation coefficient was with F. poae DNA.  
Próby ziarna jęczmienia jarego ze zbiorów w 2009 i 2010r. zostały przeanalizowane pod kątem zawartości DNA gatunków Fusarium i toksyn fuzaryjnych (trichotecenów B). Próbki pochodziły z różnych pól z Radzikowa, w środkowej Polsce. Jakościowe i ilościowe oznaczanie gatunków Fusarium w ziarnie przeprowadzono techniką real-time PCR. Toksyny fuzaryjne w ziarnie analizowano metodą chromatografii gazowej. W ziarnie jęczmienia wykryto siedem gatunków Fusarium. Dominujące gatunki to F. avenaceum, F. graminearum i F. poae. Wykryto również występowanie F. culmorum, F. langsethiae, F. sporotrichioides i F. tricinctum. Stężenie trichotecenów B (deoksyniwalenolu, niwalenolu) w ziarnie było niskie. Najwyższy współczynnik korelacji deoksyniwalenol vs. DNA Fusarium stwierdzono dla F. graminearum. Jeśli chodzi o niwalenol, najwyższy był współczynnik korelacji z DNA F. poae.

Opis:

Celem artykułu jest dokonanie charakterystyki założeń koncepcji real-time marketingu jako pozytywnie odbieranego narzędzia komunikacji i kreowania wizerunku, a także ukazanie przejawów jej stosowania przez przedsiębiorstwa w odpowiedzi na wydarzenie kulturowe. Przyjęto, że działania tego typu spełniają sformułowane w teorii postulaty szybkiej reakcji i kreatywnego przekazu, który często wykorzystuje humor, stając się tym samym atrakcyjną informacją, pobudzającą konsumentów do reakcji. W artykule zastosowano podejście badawcze oparte na studiach piśmiennictwa – dokonano przeglądu literatury przedmiotu dotyczącej badanej problematyki oraz źródeł wtórnych. Skupiono się na stronach internetowych w mediach społecznościowych wybranych przedsiębiorstw (Facebook, Instagram). Na tej podstawie poddano analizie zawartość komunikatów opartych na przetworzonej idei związanej z wydarzeniem kulturowym w postaci samozniszczenia obrazu Dziewczynka z balonikiem.
The aim of the article is to characterize the assumptions of the concept of real-time marketing as a communication and image creation tool. An important goal is also to characterize the symptom of real-time application by enterprises in response to a cultural events. It was assumed that such actions correspond to the theoretical postulates of fast reaction and creative message, which often uses humor. They become the same attractive information that stimulates consumers to react. The article reviews the literature on the subject matter under analysis and secondary sources, especially the websites on social media of selected enterprises (Facebook, Instagram). Messages based on a cultural event – self-destruction of Girl with Balloon image was analyzed.

Opis:

Currently there is growing interest in unmanned shipping. In the case of unmanned ‘autonomous’ shipping, navigation is automated by on-board decision-making systems. Important motives for unmanned ships include the shortage of skilled mariners, the facilitation of slow steaming strategies, efficiency improvements in confined shipping areas, and increased safety. The aim of the present research is to simulate an unmanned ship through an Automatic Identification System (AIS) based traffic situation. In order to do this, the Maritime Research Institute Netherlands (MARIN) will use the existing simulation technology Dolphin, implement a new tool to read AIS data, simulate a large amount of ships, and develop an auto-captain. The real-time dynamic risk index developed by MARIN will be integrated in Dolphin, to monitor nautical safety of all ships with focus on the unmanned ship. The simulated unmanned ship will navigate according to the International Regulations for Preventing Collisions at Sea (COLREGS). In more complex situations, the auto-captain may use a dedicated decision support tool to find a more efficient solution to pass safely. This approach will be analysed using the real-time dynamic risk index, which will be updated based on latest insights. This paper will discuss the latest development and plans in the unmanned ship simulation project.

Opis:

The aim of this study was to evaluate the usefulness of quantitative real-time PCR (RQ-PCR) for the monitoring of molecular remission in follicular lymphoma (FL) patients during long-term follow-up. RQ-PCR by the use of TaqMan® detection system is a sensitive tool to monitor minimal residual disease (MRD) in FL through amplification of the t(14;18) fusion gene during and post-therapy. In most cases the breakpoint region occurs within the major breakpoint region (MBR). Among 75 patients diagnosed with FL, cells harboring the fusion gene BCL2/JH were found in peripheral blood of 31 patients (41%). We further monitored 30 of these patients in a period varying from 6 months to 5 years by RQ-PCR. In our study the level indicating the possibility of the presence of MRD was established at more than five t(14;18)-positive cells in the background of 83000 normal cells. The results of this work also confirmed that the presence of MRD detected by RQ-PCR is an indication for careful observation of patients because of a higher risk of disease recurrence.

Head movement is frequently associated with human motion navigation, and an indispensable aspect of how humans interact with the surrounding environment. In spite of that, the incorporation of head motion and navigation is more often used in the VR (Virtual Reality) environment than the physical environment. This study aims to develop a robot car capable of simple teleoperation, incorporated with telepresence and head movement control for an on-robot real-time head motion mimicking mechanism and directional control, in attempt to provide users the experience of an avatar-like third person’s point of view amid the physical environment. The design consists of three processes running in parallel; Motion JPEG (MJPEG) live streaming to html-Site via local server, Bluetooth communication, and the corresponding movements for the head motion mimicking mechanism and motors which acts in accordance to head motion as captured by the Attitude Sensor and apparent command issued by the user. The design serves its purpose of demonstration with the usage of basic components and is not aimed to provide nor research with regards to user experience.

Opis:

In recent years, with the increasing popularity of IoT, the rapid growth of smartphone usage enabled by the increase adoption of Internet services and the continuously decreasing costs of these devices and services has led to a huge increase in the volume of data that governments can use in the context of smart city initiatives. The need for analytics is becoming a requirement for smart city projects such as city dashboards to provide citizens with an easy to understand overview of the city. As such, data should be analyzed, reduced and presented in such a way that citizens can easily understand various aspects of the city and use this information to increase quality of life. In this paper, we firstly present the context and the start of the design and implementation of proposed solution for real-time data processing in smart cities, mainly an analytics processing pipeline and a dashboard prototype for this solution, named My City Dashboard. We focus on high scalability and modularity of this platform.

Opis:

Machining accuracy can be considerably affected by deflections of machine tool components and the workpiece. This work presents a new approach for real-time deflection compensation, based on control integrated models. A real-time material removal rate (MRR) simulation determines the depth of cut which is used for process force calculation by Kienzle-Equations. Machine tool and workpiece deflections are then derived from a mechanical model using the calculated process forces. For this purpose, control based signals are used as model inputs. The total deviation is sent to the position controller as a setpoint offset. A dynamometer was applied to validate the simulated process forces. The presented approach was validated for cylindrical turning operations on chucked steel shafts. The experiments were carried out on a high-precision slant bed lathe. The results show, that geometrical errors could be reduced by more than 70% on average.

The problem of real time requirements especially refers to digital video watermarking algorithms. This paper contains a description of the algorithm consisting of real time coding process in the luminance component in the spatial domain and not real time decoding process in the two dimensional Cepstrum domain. The algorithm makes the single I-frame robust against the following attacks: MJPEG compression, cropping, affine transform (two-dimensional shearing, rotation, translation). Also the Receiver Operating Curves have been performed for the above mentioned attacks. Watermarked digital stream is robust against desynchronization attack.
Wymóg pracy w czasie rzeczywistym jest szczególnie ważny w znakowaniu wodnym cyfrowych strumieni wideo. Artykuł zawiera opis algorytmu znakującego w czasie rzeczywistym macierzy luminancji w dziedzinie przestrzeni. Proces dekodowania odbywa się w dwuwymiarowej przestrzeni Cepstralnej. Metoda znakująca uodparnia pojedynczą I-klatkę na ataki: kompresji MJPEG, przycinanie, przekształcenia afiniczne (dwuwymiarowe skręcenie, rotację, translację). Ponadto algorytm jest odporny na atak desynchronizacji. Dla przeprowadzonych ataków obliczono Charakterystyki Operacyjne ukazujące efektywność metody.

The aims of this study were to evaluate the prevalence of Coxiella burnetii on both herd and animal level based on ELISA and PCR tests. Antibodies to C. burnetii were detected in 22 out of the 24 bulk tank milk samples (91.6%) tested by ELISA and the IS1111 element of C. burnetii was detected in 10 out of the 24 samples (41.6%) by real-time polymerase chain reaction (PCR). ELISA testing showed individual seropositivity in 67 out of the 165 cows (40.6%) examined in 24 dairy cattle farms in different parts of the Czech Republic. Our study revealed that the prevalence of C. burnetii has increased substantially in the Czech Republic over the past 30 years, and that the causative agent is a potential risk factor for some reproductive problems in dairy farms and a possible risk factor for human infection.

Opis:

In this study, we report the cloning and characteristics of an adiponectin-like receptor gene from Bombyx mori (BmAdipoR) with highly conserved deduced amino-acid sequences and similar structure to the human adiponectin receptor (AdipoR). Structural analysis of the translated cDNA suggested it encoded a membrane protein with seven transmembrane domains. BmAdipoR was found to be expressed in multiple tissues and highly expressed in Malpighian tubules, fat body and testis. BmNPV (Bombyx mori nucleopolyhedrovirus) bacmid system combined with confocal microscopy revealed that BmAdipoR was targeted to the cell membrane. We also found that infection with BmNPV did not have an effect on BmAdipoR mRNA quantity in the midgut of susceptible Bombyx mori strain (306) at 48 h, but BmAdipoR mRNA quantity increased significantly at 72 h. We concluded that BmAdipoR gene was a membrane protein ubiquitously expressed in Bombyx mori tissues and that its expression was altered by treating with BmNPV.

Opis:

Thioredoxin (Trx) is a multifunctional protein with a redox-active disulfide/dithiol in the active site. Thioredoxin, with its redox-regulating and reactive oxygen species (ROS) scavenging activities, plays several important biologic roles both in intracellular and extracellular compartments. The purpose of this report was to quantify the relative expression of Trx in rat hippocampus following an oxidative stress-involving treatment such as kainic acid (KA) using real-time PCR and the 2-ΔΔCT method. The relative changes in expression of Trx mRNA in KA-treated and control animals were significantly different as 2.02 ± 0.77 and 1.0 ± 0.26, respectively ( P <0.05). Minimum and maximum n-fold changes in Trx expression in KA-treated and control animals were determined as (1.4-5.2) and (0.8-1.3), respectively. Thus, real-time PCR and the 2-ΔΔCT method for data analysis from real-time PCR were found to be an accurate and sensitive method for quantifying Trx mRNA levels.

Opis:

The aim of this study was to analyse the correlation between a new multiplex qPCR assay and a reference qPCR assay for assessment of the human papillomavirus (HPV16) load and the viral genome status. The study was performed on 100 HPV16 positive samples containing premalignant lesions and carcinomas. HPV16 E2 and E6 gene loads were assessed by two PCR methods. The load of E2 and E6 was normalized to the cell number by qPCR targeting the RNase P open reading frame. The physical state of the viral genome was determined as a ratio of E2/E6 copies number per cell. Among 100 samples analysed, there were no statistically significant differences in the E2 and E6 viral load evaluated by multiplex qPCR and qPCR, the correlation coefficients were 0.98 and 0.97, respectively. There were 19% of samples with the integrated, 73% with mixed and 8% with episomal state of viral genome detected by multiplex qPCR and 17%, 79%, 4%, respectively, found by qPCR. Prevalence of integrated and episomal forms estimated by multiplex qPCR was higher than the one obtained by qPCR (Chi2, p < 0.0001), but in samples with premalignant and malignant diagnoses no significant differences were demonstrated regardless of the methods used. Sensitivity and specificity of multiplex qPCR were 93.7% and 100% as compared with qPCR, the positive predictive value was 100%. In summary, the multiplex qPCR assay in respect of HPV16 load and the frequency of viral genome status was shown to be a sensitive and specific reference method. Simultaneous estimation of E2 and E6 genes in one reaction tube reduces the cost of testing.

This paper presents an optimal scheduling solution for a case of agents sharing a resource. The amount of resource can not satisfy all agents at once and in case of runout there is a penalty. Each agent randomly toggle its state between requiring and not requiring the resource. Using the knowledge of previous state and probability of change, the scheduling algorithm is able to calculate optimal number of concuring agents for one turn, that minimizes possibility of collision yet provides as much throughput as possible. Several different scheduling strategies are tested. The optimal solution adapts automatically to the value of probability of change. Further experiments show that optimality is retained if only the average probability of a set of agents is known. A case of practical application is provided.

Opis:

Traditionally, control algorithms are designed without a consideration of their real-time implementation details. The performance of a digital control system, besides the sampling period, depends on many variables, such as the control loop execution time, jitter, complexity of the control algorithm etc. In this paper attention is focused on the inter-action of the parameters of the scheduled tasks and on the performance of control loops closed with digital controller. A design approach that is based on the relative speed classification of the control system has been proposed. The approach is illustrated by the analysis of control systems developed for laboratory magnetic levitation process.

Opis:

Newcastle disease virus (NDV), member of the Paramyxoviridae family and avian influenza virus (AIV), member of the Orthomyxoviridae family, are two main avian pathogens causing serious economic problems in poultry health. Both are enveloped, single-stranded, negative-sense RNA viruses and cause similar symptoms, ranging from sub-clinical infections to severe diseases, including decrease in egg production, acute respiratory syndrome, and high mortality. Similar symptoms hinder the differentiation of infection with the two viruses by standard veterinary procedures like clinical examination or necropsy. To overcome this problem, we have developed a new duplex real-time PCR assay for the detection and differentiation of these two viruses. Eighteen NDV strains, fourteen AIV strains, and twelve other (negative control) strains viruses were isolated from allantoic fluids of specific pathogen-free (SPF), embryonated eggs. Four-weeks-old SPF chickens were co-infected with both viruses (NDV - LaSota and AIV - H7N1). Swabs from cloaca and trachea were collected and examined. The results obtained in this study show that by using duplex real-time PCR, it was possible to detect and distinguish both viruses within less than three hours and with high sensitivity, even in case a bird was co-infected. Additionally, the results show the applicability of the real-time PCR assay in laboratory practice for the identification and differentiation of Newcastle disease and influenza A viruses in birds.

Opis:

Hyperparathyroidism (pHPT) is a relatively frequent endocrinopathy, however, the molecular mechanisms of its etiology remain poorly understood. This disorder is mainly associated with benign tumours (adenoma) and hyperplasia of the parathyroid, hence, the focus is directed also to genes that are likely to be involved in carcinogenesis. Among such genes are ErbB/Her family genes already used in diagnosis of other tumours (e.g., breast carcinoma) and reported also to play a role in development of endocrine lesions. So far, ErbB-1/Her-1/EGFR expression has been detected in pHPT-associated adenomas and hyperplasia as opposed to no expression in normal parathyroid tissue. Moreover, losses or gains of the fragments of chromosomes where ErbB/Her genes are located have been reported. In this study, the gene dosage of ErbB/Her family genes were determined for the first time in parathyroid adenomas, hyperplasia and morphologically unchanged tissue in order to establish their putative role in the development of the disease. Genomic DNA was isolated from 33 patients with sporadic hyperparathyroidism and the gene copy numbers were assessed using real-time PCR. The ErbB/Her genes' profile was unaltered in most of the examined samples. Two low-level amplifications of ErbB-1/Her-1/EGFR gene, two deletions of ErbB-2/Her-2, and six deletions of ErbB-4/Her-4 were found. The ErbB-3/Her-3 gene remained unaffected. No correlation with clinical parameters was found for any gene. Both the low number of alterations and a lack of their associations with clinical parameters exclude the prognostic value of the ErbB/Her genes family in parathyroid tumourigenesis. Nevertheless, the ErbB-4/Her-4 deletions seem to be interesting for further investigations, especially in the context of PTH secretion.

Opis:

Natural gas is a mixture of 21 components and it is widely used in industries and homes. Knowledge of its thermodynamic properties is essential for designing appropriate processes and equipment. This paper presents simple but precise correlations of how to compute important thermodynamic properties of natural gas. As measuring natural gas composition is costly and may not be effective for real time process, the correlations are developed based on measurable real time properties. The real time properties are temperature, pressure and specific gravity of the natural gas. Calculations with these correlations are compared with measured values. The validations show that the average absolute percent deviation (AAPD) for compressibility factor calculations is 0.674%, for density is 2.55%, for Joule-Thomson coefficient is 4.16%. Furthermore, in this work, new correlations are presented for computing thermal properties of natural gas such as enthalpy, internal energy and entropy. Due to the lack of experimental data for these properties, the validation is done for pure methane. The validation shows that AAPD is 1.31%, 1.56% and 0.4% for enthalpy, internal energy and entropy respectively. The comparisons show that the correlations could predict natural gas properties with an error that is acceptable for most engineering applications.

Opis:

Thermal errors caused by internal and external heat sinks and sources may cause more than 50% of machine tool (MT) total error. Demands on machining accuracy and machine time utilization are still increasing. Therefore, research on thermal behaviour of MT structures is crucial for successful manufacturing. Direct (measuring between tool and work-piece) and indirect (predictive models) approaches to compensation of thermo-dependent tool centre point (TCP) displacement can be used to reduce sensitivity to heat flow or temperature control of MT and its environment. Thermal error indirect compensation is one of the techniques widely employed to reduce thermal errors due to its cost-effectiveness and ease of implementation. This paper is a continuation of scientific work on the modelling of complex MT thermal behaviour using a dynamic method with a physical basis: thermal transfer functions (TF). Previously published works focusing on middle-sized MTs are extended here to include heavy-duty MT application. Particular attention is paid to issues concerning compensation of thermal errors caused by interchangeable spindle heads.

The paper presents the results of a simulation of operating conditions of a two-sectioned medium-voltage power line, with the use of a simulator based on a multi-core signal processor. It is a kind of type of a real-time digital simulator of electrical system. Steady states and transients were analyzed, as well as the switching operation of the load with zero initial conditions. The transient states of this electrical system was also analyzed during one and multi phase short-circuit. The oscillograms of steady and transient node system voltages and currents registered during simulator work were presented. The obtained results were compared to the ones received via Matlab simulation package. The estimated maximum errors of the simulator in steady and transition states were presented. The method of simulation, which is used in the implementation of discreet mathematical models of the complex electrical systems in real-time simulators, was applied. The main advantage of the simulator is the ability of its cooperation with real devices (e.g. regulators).

Opis:

This paper deals with the image processing from the camera for Raspberry Pi connected with real-time communication network to the control system (PLC). The low time delay for receiving and sending commands, data, etc. is very important in the automating production processes. This can be provided by industrial real-time network based on Ethernet. The Ethernet POWERLINK, which is supported on B&R PLCs, is one of them. It is a simple solution for a variety of applications because the POWERLINK is publicly available as the open source. Connecting the PLC and Raspberry Pi with Ethernet POWERLINK opens up many applications in industrial automation. For example, image data obtained using a camera attached to Raspberry Pi can be used to sense image of manufacturing processes and products and evaluate their quality in industrial automation. This article focuses on an image processing unit and the PLC system with CPU redundancy used in the industrial application. Vision systems are often used to improve products quality control, saving costs and time.

Opis:

Personal positioning is facing a huge challenge to maintain a reliable accuracy through all applications. Although in outdoor applications, several mobile navigation devices can provide acceptable positioning accuracy, the situation in indoor environment is not the same. Mobile navigation devices mainly contain a global positioning system (GPS) receiver and an inertial measurement unit (IMU). The main drawback in indoor navigation applications is the unavailability of the GNSS signals, which decreases the possibility of obtaining an accurate absolute position solution, as the inertial system (INS) solution will drift with time in the absence of external updates. Several alternatives were presented lately to update the inertial solution such as using Wi-Fi, UWB, RFID, several self-contained sensors, imaging aiding and spatial information aiding. In order to achieve accurate position solution, with low-cost and usable technique, an integrated mobile navigation system integrating GPS/IMU/Wi-Fi and map-matching was developed. The developed system uses the prior knowledge of the indoor geometrical and topological information, as a threshold for the navigation solution, forcing the provided solution to be mostly on the right track. The geometrical and topological information for the building was used to build the geospatial data model. The use of this model was performed by developing a map matching algorithm which uses the geometrical and topological characteristics of the building to locate the user position on the building map. This algorithm was developed based on the geospatial information of the Engineering building, University of Calgary, where the field test occurred. The map-matching algorithm was evaluated by processing and comparing two separate navigation solutions through the study area, one using only the GPS/IMU/Wi-Fi system, and second solution was assisted with the map-matching algorithm which shows significant enhancement in the position solution for the indoor trajectory.

Opis:

Investigation of the combustion processes occurring in end-burning, multi-segment, delay elements of hand-grenade firing-explosive trains using Real-Time X-ray Radioscopy (RTR) are presented. RTR detection, operating at 30 frames per second, registered the development of the combustion process, visualized as the border between the burnt and unburnt parts of the pyrotechnic column, travelling from the ignition (input) end to the output end. This border had a variable shape, ranging from planar to very non-regular. At the end of the combustion process, i.e. during burning of the final-output pyrotechnic segment, the formation of a longitudinal cavity beginning from the output end of the delay element and reaching a depth of nearly 40% of the total length of the pyrotechnic column, was detected. Such strong erosion of the output part of the pyrotechnic column indicates that in the creation of the output combustion products (firing output impulse) of the tested delay element, a relatively significant mass of the pyrotechnic charge was involved.

Budowa nowych oraz utrzymanie istniejących linii kolejowych, a także modernizacje nawierzchni kolejowych, polegające na przystosowaniu ich do wyższych parametrów techniczno-eksploatacyjnych stawiają wysokie wymagania wykonawcom robót geodezyjnych. Rozwój technik pomiarowych pozwala na opracowywanie nowych technologii realizacji pomiarów geodezyjnych. W pracy przedstawiono techniki pomiarów satelitarnych oraz istotę synergicznego wykorzystania ich wraz z pomiarami naziemnymi w geodezyjnej obsłudze inwestycji o charakterze liniowym. Wskazano również na zagrożenia dla jakości wyników pomiarów satelitarnych, czy wręcz przeciwwskazania dla wykorzystywania na terenach kolejowych najnowszej techniki satelitarnych sieciowych pomiarów kinematycznych w czasie rzeczywistym. Zagadnienie jakości pomiarów geodezyjnych nabiera szczególnego znaczenia przy realizacji odcinków kolei dużych prędkości.
The construction of a new railway track and maintenance of existing ones as well as railway superstructure modernisation relying on their adjustment to higher technical and operational parameters cause high requirements for executors of geodesic survey. The measurement technic development allows to elaborate some new technologies of geodesic survey. The technic of satellite measurement and the essence of their synergic usage together with ground survey in geodesic service of linear investment have been presented. The threats for the quality of the results of satellite survey and even the contraindications for the usage of modern satellite network technics in real time on the railway areas have been given. The problem of geodesic survey quality seems to be especially essential while high speed railway tracks execution.

Opis:

Proximate to the environment, adipose fin of fish may be considered as a lipid storing tissue, and thus can be a target for either waterborne or dietary polycyclic aromatic compounds (PACs). We determined the effects of benzo[a]pyrene (B[a]P), a model PAC member, on CYP1A gene expression in adipose fin and compared that with the effects in gill of juvenile rainbow trout (Oncorhynchus mykiss Walbaum) using the quantitative reverse transcription polymerase chain reaction (Q-RT-PCR). The results of the study demonstrated that constitutive CYP1A mRNA was present in adipose fin of rainbow trout, but the transcripts were far less abundant than those in gill tissue. We confirmed high CYP1A gene induction potential of the gills in rainbow trout injected with benzo[a]pyrene, but also showed moderately and transiently induced CYP1A mRNA in adipose fin. The modest and transitory gene expression may preclude rainbow trout adipose fin CYP1A mRNA levels from using it as an indicator of sustained exposure of fish to the polycyclic aromatic compounds.

Opis:

W niniejszym artykule przedstawiono badania związane z pomiarem temperatury, jako jednego z symptomów uszkodzenia przekładni, na stanowisku mocy zamkniętej z wykorzystaniem wybranych elementów automatyki. Stanowisko badawcze podłączone było do sieci Ethernet, w ramach której odbywała się komunikacja z urządzeniami wykonawczymi oraz rejestracja wyników. Realizując badania skupiono się na wyznaczeniu czasu dostępu do urządzeń z wykorzystaniem protokołu http.
Aiming for assurance of constant work of a particular machine, monitoring of its current technical characteristics is needed nowadays. In many cases, devices allowing for performance of this task have an option of a remote monitoring as well as configuration via a WLAN network. Usually, a protocol TCP/IP is used. It is a very convenient solution because via an internet browser or a program of Telnet type - a serviceman can connect to an adequate device and analyze the registered data. However, it is worth recognizing whether an access time (to the device) as well as a delay time after which information is presented on the monitoring screen is sufficient for making a decision e.g. connected with emergency on-off switch of the machine. Therefore, in this paper, an attempt of analysis of the gear monitoring system is described. We measured the duration time of a transaction of data exchange in the proposed (applied) distributed monitoring system of the power-closed-loop gear. In our case, TCP/IP stack of protocols was responsible for data exchange. In majority of installations for diagnostics - PLC industrial controllers are used. They are also equipped with PID or FLC controllers. They enable simultaneous registering and analyzing (in a real time) of several symptoms characteristic for machine work status. However, some manufacturers offer series of new industrial solutions which allow for an access using the http protocol - i.e. for example via an internet browser. A diagnostic procedure enabling spotting/detection of a failure e.g. during a work of a gear - without any necessity of its disassembly and breakage in service duties - ensures reducing the stoppage time as well as preventing a failure of the entire system i.e. drive system.

Experimental Real Time X-ray Radioscopy (RTR) investigation of dynamic phenomena occurring during the combustion of end-burning pyrotechnic charges confined in the fuze body, utilized in the delay systems of 40 mm grenade fuzes, are presented. These pyrotechnic delay systems delay the arming distance pyromechanism and the self-destroying timing assembly. The charge in the delay arming distance pyromechanism was a black powder pellet supported by the safety pin kept in constant position by its driving compressed spring. The self-destroying timing assembly comprised three pyrotechnic segmented columns connected at their ends with ignition relay channels, creating a zig-zag firing train. The following dynamic phenomena were detected and registered by RTR at a frequency of 30 FPS: (i) combustion zone travelling along the pyrotechnic charges, (ii) displacements of the pyromechanism safety pin caused by either the pressure of its spring after burning out of the black powder pellet or by pressure of the combustion products escaping from the zig-zag firing train, (iii) transfer of the ignition impulse between the adjacent pyrotechnic columns, (iv) pressure action of the combustion products on the pyrotechnic columns during transfer of the ignition impulse, and (v) transfer of the final output ignition impulse from the last (third) pyrotechnic column through the channel leading directly to the chamber used for accommodating the fuze detonator.

But this implies using tools for storing the data, to manage it, look at it, understand it, exploit it, generate actions such as marketing campaigns. It is therefore obvious that using one tool for each of these functions will discuss here the technical issues involved and show how we turned them into an easy-to-use solution for business users.
