Opis:
The conventional control system is a controller that controls or regulates the dynamics of any other process. From time to time, a conventional control system may not behave appropriately online; this is because of many factors like a variation in the dynamics of the process itself, unexpected changes in the environment, or even undefined parameters of the system model. To overcome this problem, we have designed and implemented an adaptive controller. This paper discusses the design of a controller for a ball and beam system with Genetic Model Reference Adaptive Control (GMRAC) for an adaptive mechanism with the MIT rule. Parameter adjustment (selection) should occur using optimization methods to obtain an optimal performance, so the genetic algorithm (GA) will be used as an optimization method to obtain the optimum values for these parameters. The Linear Quadratic Regulator (LQR) controller will be used as it is one of the most popular controllers. The performance of the proposed controller with the ball and beam system will be carried out with MATLAB Simulink in order to evaluate its effectiveness. The results show satisfactory performance where the position of the ball tracks the desired model reference.

Opis:
Artificial neural network models (ANNs) were used in this study to predict reference evapotranspiration (ETo) using climatic data from the meteorological station at the test station in Kafr El-Sheikh Governorate as inputs and reference evaporation values computed using the Penman-Monteith (PM) equation. These datasets were used to train and test seven different ANN models that included different combinations of the five diurnal meteorological variables used in this study, namely, maximum and minimum air temperature (Tmax and Tmin ), dew point temperature (Tdw), wind speed (u), and precipitation (P), how well artificial neural networks could predict ETo values. A feed-forward multi-layer artificial neural network was used as the optimization algorithm. Using the tansig transfer function, the final architected has a 6-5-1 structure with 6 neurons in the input layer, 5 neurons in the hidden layer, and 1 neuron in the output layer that corresponds to the reference evapotranspiration. The root mean square error (RMSE) of 0.1295 mm∙day -1 and the correlation coefficient (r) of 0.996 are estimated by artificial neural network ETo models. When fewer inputs are used, ETo values are affected. When three separate variables were employed, the RMSE test values were 0.379 and 0.411 mm∙day -1 and r values of 0.971 and 0.966, respectively, and when two input variables were used, the RMSE test was 0.595 mm∙day -1 and the r of 0.927. The study found that including the time indicator as an input to all groups increases the prediction of ETo values significantly, and that including the rain factor has no effect on network performance. Then, using the Penman-Monteith method to estimate the missing variables by using the ETo calculator the normalised root mean squared error (NRMSE) reached about 30% to predict ETo if all data except temperature is calculated, while the NRMSE reached about of 13.6% when used ANN to predict ETo using variables of temperature only.

Product with cylindrical surfaces are found in various branches of industry, for instance, in the paper, chemical, steel, heating, and shiping industries. To assure high quality of cylindrical products, it is required that regular assessment of cylindricity profiles be conducted both during the manufacturing process as well the product operation. Cylindricity measurements under industrial conditions are not easy though. the researches from the Kielce University of Technology have come up with a new approach to measurements of cylindricity (shown in fig. 1) and developed a concept of so-called reference cylindricity measurement. The concept was used to construct a model of measuring stand for reference cylindricity measurements (see Fig. 2). In order to verify developed method the results obtained values of parameters were used to establishing the value of the error of proposed method (see Table 1).

Opis:
In this article, model reference adaptive system (MRAS)-based estimator of a rotor resistance of an induction motor (IM) is presented. In contrast to the solutions known from the literature, the reference model of this estimator uses the measured values of the phase current and the adaptive part is a virtual current sensor. The article presents an accurate description of the algorithm taking into account the discrete equations for possible practical implementation in the microprocessor system. In the first step, the impact of motor parameters to stator current estimation quality in the adaptive model was checked. Subsequently, simulation tests of the proposed rotor resistance estimator were carried out for the field-oriented control of the induction motor drive system with a model of an induction motor with fixed parameters and an induction motor with a changing main inductance according to a magnetisation curve. The analysis of the estimator’s work showed its high efficiency and insensitivity to changes in the IM main inductance.

Opis:
In this paper, I present Christine Korsgaard’s style of building a conception of animal rights protection based on a concept of Kantian provenance, namely “end in itself”. Considering that an end in itself in Immanuel Kant’s philosophy includes only human beings, the American philosopher needed to modify (extend) the meaning of the abovementioned concept. This study aims at showing this change of the meaning in categories derived from Fregean semantics (sense and reference). Moreover, I will attempt to prove that by broadening the extension of “end in itself” Korsgaard uses a strategy called ethical extensionism and situates the revised (naturalized) categorical imperative ipso facto within environmental ethics. I start with elucidating Korsgaard’s views on the meaning of “end in itself” before she took interest in animal rights (set out mainly in Kant’s Formula of Humanity and The Sources of Normativity) and then I synthetically describe her animal rights philosophy with a special regard to the category of “natural good”. The second part of the article explains the methodology used in the paper, while the last part is intended to be an interpretation of Korsgaard’s thought.

Opis:
A sensorless indirect stator-flux-oriented control (ISFOC) induction motor drive at very low frequencies is presented herein. The model reference adaptive system (MRAS) scheme is used to estimate the speed and the rotor resistance simultaneously. However, the error between the reference and the adjustable models, which are developed in the stationary stator reference frame, is used to drive a suitable adaptation mechanism that generates the estimates of speed and the rotor resistance from the stator voltage and the machine current measurements. The stator flux components in the stationary reference frame are estimated through a pure integration of the back electro-motive force (EMF) of the machine. When the machine is operated at low speed, the pure integration of the back EMF introduces an error in flux estimation which affects the performance torque and speed control. To overcome this problem, pure integration is replaced with a programmable cascaded low-pass filter (PCLPF). The stability analysis method of the MRAS estimator is verified in order to show the robustness of the rotor resistance variations. Experimental results are presented to prove the effectiveness and validity of the proposed scheme of sensorless ISFOC induction motor drive.

Evapotranspiration represents one of the main parameters in the hydrological cycle. It is usually expressed by the term reference evapotranspiration (ETo) that is affected by certain meteorological parameters. This study aimed to find the difference amount in ETo between urban and suburban quarters in Karbala city. The study methodology involved selecting once urban area and four suburban quarters. Two methods of determining the reference evapo- transpiration were applied: first, a direct method which measured ETo at selected fields by using a hand-held device, and second, an indirect method using the Penman-Monteith equation. The findings showed that the magnitudes of ETo by the Penman-Monteith equation are higher than the values measured by the direct method for urban and suburban quarters. Moreover, it was found that the absolute percentage of difference in the average amount of ETo between urban and suburban quarters is 13% by using the direct method and 61% by using Penman-Monteith equation. The study conclusion is that suburban area has higher magnitude of ETo than urban quarter by using any of direct method and indirect method (Penman-Monteith equation).

Context: In software engineering, snowball sampling has been used as a supplementary and primary search strategy. The current guidelines recommend using Google Scholar (GS) for snowball sampling. However, the use of GS presents several challenges when using it as a source for citations and references. Objective: To compare the effectiveness and usefulness of two leading citation databases (GS and Scopus) for use in snowball sampling search. Method: We relied on a published study that has used snowball sampling as a search strategy and GS as the citation source. We used its primary studies to compute precision and recall for Scopus. Results: In this particular case, Scopus was highly effective with 95% recall and had better precision of 5.1% compared to GS’s 2.8%. Moreover, Scopus found nine additional relevant papers. On average, one would read approximately 15 extra papers in GS than Scopus to identify one additional relevant paper. Furthermore, Scopus supports batch downloading of both citations and papers’ references, has better quality metadata, and does better source filtering. Conclusion: This study suggests that Scopus seems to be more effective and useful for snowball sampling than GS for systematic secondary studies attempting to identify peer-reviewed literature.

Opis:
More than half of the incidents reported to EMSA relate to nautical events such as collision, groundings and contacts. Knowledge of accurate and high-integrity positioning is therefore not only a need for future automated shipping but a base for today’s safe navigation. Examples on accidents include Ever Given in the Suez Canal and HNoMS Helge Ingstad in Norway. A Network-RTK (NRTK) service can be used as an augmentation technique to improve performance of shipborne GNSS receivers for future positioning of manned and unmanned vessels in restricted areas, such as port areas, fairways, and inland water ways. NRTK service providers generate RTK corrections based on the observations of networks of GNSS reference stations which enables the users to determine their position with centimeter accuracy in real-time using a shipborne GNSS receiver. Selection of appropriate communication channels for dissemination of NRTK corrections data is the key to a secure positioning (localization) service. In PrePare-Ships project, the modern maritime communication system VDES (VHF Data Exchange System) is proposed to distribute SWEPOS (NRTK in Sweden) correction data to shipborne positioning modules. VDES is a very reliable technique and it is compatible with most onboard functionalities. In order to minimize the impact on the overall VDES data capacity in a local area, NRTK correction data shall only occupy a single VDES slot with a net capacity of 650 bytes. Update rates may vary but are preferably at 1Hz. However, NRTK correction data size changes instantly, depending on the number of visible GNSS satellites, and the data rate can therefore sometimes reach in excess of 1000 byte/s. In this study, a smart technique is proposed to reduce size of NRTK correction data to instantly adapt with the VDES requirements by choosing a combination of specific signals, satellites or even constellations such that the data rate is not more than 650 byte/s, and at the same time it achieves optimal positioning performance with the accuracy required by the PrePare-Ships project application.

Introduction and aim. Following the use of repurposing drugs to successfully manage coronavirus disease 2019 (COVID-19) patients in an Infectious Diseases Center (IDC) in Nigeria, it was imperative to assess haematological changes and metabolic alterations in these patients which may inform recommendations for future use. Material and methods. Blood samples of admitted COVID-19 Nigerian patients during therapeutic management were analysed for haematological- (total white blood cells (WBC), lymphocyte, monocyte, neutrophil, eosinophil, basophil and neutrophil:lymphocyte ratio) and blood chemistry- parameters [total protein, total and conjugated bilirubin, alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine transaminase (ALT), gamma-glutamyl transferase (GGT), albumin, urea, creatinine, total cholesterol, triglycerides, low-density lipoprotein (LDL), high-density lipoprotein (HDL), PO₄³⁻, Ca²⁺, uric acid, Na⁺, K⁺, Cl⁻ and HCO₃⁻] using autoanalysers. The percentages of patients having values below, within and above reference ranges were compared using Chi-square test while the mean values at admission were compared with mean values at discharge using Student t-test. Results. The mean values of total protein, albumin, Na⁺, HCO₃⁻, uric acid, Ca²⁺, WBC, platelets, lymphocytes, eosinophils and basophils were significantly increased in COVID-19 patients at discharge compared with COVID-19 patients at admission. Also, more percentages of COVID-19 patients at discharge compared with COVID-19 patients at admission had albumin, ALP, total bilirubin, HDL, Na⁺, K⁺, Cl⁻, HCO₃⁻, urea, creatinine, WBC, lymphocytes, neutrophils, monocytes, eosinophils and basophils within normal reference intervals. Conclusion. This study showed that most metabolic and haematological derangements were normalised by repurposing drugs in most of the COVID-19 patients at this IDC, thus supporting the continuous use of this therapeutic option.

Opis:
Contrary to what non-practitioners might expect, the systems of phonetic notation used by linguists are highly idiosyncratic. Not only do various linguistic subfields disagree on the specific symbols they use to denote the speech sounds of languages, but also in large databases of sound inventories considerable variation can be found. Inspired by recent efforts to link cross-linguistic data with help of reference catalogues (Glottolog, Concepticon) across different resources, we present initial efforts to link different phonetic notation systems to a catalogue of speech sounds. This is achieved with the help of a database accompanied by a software framework that uses a limited but easily extendable set of non-binary feature values to allow for quick and convenient registration of different transcription systems, while at the same time linking to additional datasets with restricted inventories. Linking different transcription systems enables us to conveniently translate between different phonetic transcription systems, while linking sounds to databases allows users quick access to various kinds of metadata, including feature values, statistics on phoneme inventories, and information on prosody and sound classes. In order to prove the feasibility of this enterprise, we supplement an initial version of our cross-linguistic database of phonetic transcription systems (CLTS), which currently registers five transcription systems and links to fifteen datasets, as well as a web application, which permits users to conveniently test the power of the automatic translation across transcription systems.

Opis:
The courts of modern countries do not want to use the monopoly in the area of deciding about investments or sports cases. Henceforth, in time appeared a construction of alternative forms for solving such a dispute. They constitute an open category of proceedings solving sports disputes, which are undergoing a big evolution in some countries nowadays. Their common characteristic is the interference of a neutral third party (for example an arbitrator), with a purpose to present or propose to the parties a solution of a dispute. Arbitration is often thought as a quick and efficient method for determining controversies. The modern law prescribes formal and substantive requirements for the arbitration agreement, which must be made in writing. The requirement of a written form is also satisfied if in a contract between parties, they refer to a document containing a clause with a decision to resolve their dispute in arbitration, provided that such a contract is made in writing and the reference incorporates that clause into the contract. The principal problem related to the arbitration agreement “per relationem” or “by reference” lies in the consensual character of such agreement whereas the form of the agreement has been found to be a preliminary question to this matter. In the article the author analyses the institutional basis for obligatory arbitration in past and currently. This type of arbitration may be forced by a law, a third party (e.g. international sports federation) or a party of the legal relationship.

Opis:
We wrześniu 2006 r. uruchomiony został Małopolski Systemem Pozycjonowania Precyzyjnego (MSPP) o przeznaczeniu ogólnogospodarczym. Działania związane z utworzeniem systemu miały na celu: - zapewnienie możliwości wyznaczania z dokładnością do 3 cm pozycji dowolnego punktu za pomocą systemu satelitarnego NAVSTAR GPS i powierzchniowych poprawek RTK/DGPS generowanych na podstawie sieci równomiernie rozłożonych stacji referencyjnych; - dostarczenie narzędzia wspierającego rozwój regionalny w zakresie wykorzystania systemu GPS dla celów ogólnogospodarczych, w tym systemów teleinformatycznych do koordynacji, zarządzania i monitoringu. Prace przy MSPP obejmowały: budowę w województwie małopolskim 3 dodatkowych stacji referencyjnych (Tarnów, Nowy Targ, Proszowice), utworzenie systemu obliczeniowego do generowania powierzchniowych poprawek RTK/DGPS oraz dostawę 8 odbiorników GPS przeznaczonych do precyzyjnych pomiarów RTK. W MSPP zastosowano rozwiązanie, opracowane w firmie Trimble/Terrasat wykorzystujące technologię wirtualnych stacji referencyjnych (Virtual Reference Stations - VRS). Główne cechy funkcjonalne systemu MSPP: - otwartość systemu, a tym samym możliwość rozbudowy systemu, dołączania kolejnych stacji, wprowadzania nowych formatów udostępnianych danych; - wysoka dokładność wyznaczania pozycji (do 3 cm w poziomie) przy zachowaniu 99% poziomu ufności wyznaczenia; - udostępnianie danych w trybie 24h/365 dni (24 godziny na dobę przez 365 dni w roku); - szybkość i prostota obsługi przy zapewnieniu automatycznego wznawiania działania w przypadku wystąpienia sytuacji awaryjnych; - możliwość dystrybucji poprawek RTK/DGPS poprzez transmisję GSM/GPRS, Internet lub FM w ramach osobnych pakietów transmisji: dla całej sieci, dla każdej stacji; - generowanie i prezentacja wyników, raportów, analiz działania systemu w postaci opisowej i graficznej. Podpisanie umowy o współpracy pomiędzy Głównym Geodetą Kraju, Województwem Śląskim i Województwem Małopolskim, pozwoliło na objęcie działaniem systemu MSPP (poprawki RTK/DGPS) obszaru województw: śląskiego i małopolskiego. Dzięki udostępnieniu stacji Centrum Badań Kosmicznych w Warszawie, dane z tej stacji będą dostępne dla rejonu Warszawy, a dla obszaru pomiędzy Warszawą, Katowicami i Krakowem będą dostępne precyzyjne poprawki DGPS. Budowa MSPP została zrealizowana ze środków Zintegrowanego Programu Operacyjnego Rozwoju Regionalnego działanie 1.5 - Infrastruktura Społeczeństwa Informacyjnego - wchodzącego w skład Europejskiego Funduszu Rozwoju Europejskiego.
In September 2006, the Małopolski Precise Positioning System (Małopolski System Pozycjonowania Precyzyjnego - MSPP) for universal economic purposes was initiated. The activities related to developing the system aimed at: - ensuring an opportunity to set the position of any point with 3 cm accuracy using the NAVSTAR GPS satellite system and the RTK/DGPS surface corrections generated based on the network of evenly distributed reference stations; - providing an instrument to support regional development in using the GPS system for universal economic purposes, including ICT systems for coordination, management and monitoring. Working on MSPP included: constructing 3 additional reference stations in the Małopolskie Province (Tarnów, Nowy Targ, Proszowice), creating a computing system to generate RTK/DGPS surface corrections, and delivering 8 GPS receivers for precise RTK measurements. MSPP uses a solution developed by Trimble/Terrast company, using the Virtual Reference Stations technology (VRS). Main functional features of the MSPP: - openness of the system, which means that the system can be expanded, more stations can be added, new format of available data introduced, - high accuracy of positioning (up to 3 cm horizontally), keeping 99% level of confidence, - making data available 24h/365 days (24 hours a day, 365 days a year), - rapid and easy operation with automatic restarting option in case of emergency, - possibility to distribute RTK/DGPS corrections through GSM/GPRS transmission, the Internet or FM within separate transmission packages: for all the network and every station. Signing a cooperation agreement between the Chief National Geodesist, the Śląskie Province and the Małopolskie Province, allowed to include in the scope of the MSPP operation (RTK/DGPS corrections) the area of the two provinces. Using the station of the Space Research Centre in Warsaw makes data from this station available for the Warsaw area, and precise DGPS corrections will be available for the area between Warsaw, Katowice and Krakow. The MSPP construction has been completed by the Małopolskie Province Marshal Office with the resources of the Integrated Operational Program for Regional Development measure 1.5 - Information Society Infrastructure, constituting a part of the European Regional Development Fund.
