Opis:
Researchers in the field of instructed second language acquisition have been examining the issue of how learners interact with input by conducting research measuring particular kinds of instructional interventions (input-oriented and meaning-based). These interventions include such things as input flood, textual enhancement and processing instruction. Although the findings are not completely conclusive on whether these instructional interventions have an impact on acquisition, it is clear that we have witnessed a shift in the field from the original question “Does instruction make a difference?” to the more specific question “Does manipulating input make a difference?” In this article, the key classroom-based research conducted to measure the relative effects of different types of enhancement and manipulation is reviewed. Three main research foci are considered: (a) research measuring the effects of saturating the input with the target form (input flood), (b) research measuring the effects of different types of textual enhancements to draw learners’ attention to the target form, and (c) research measuring input restructuring to improve interpretation and processing of target forms or structures (processing instruction).

Opis:
Microscopic technology has recently flourished, allowing unparalleled viewing of microscopic elements invisible to the normal eye. Still, the existence of unavoidable constraints led on many occasions to have low contrast scanning electron microscopic (SEM) images. Thus, a noncomplex multiphase (NM) algorithm is proposed in this study to provide better contrast for various SEM images. The developed algorithm contains the following stages: first, the intensities of the degraded image are modified using a two-step regularization procedure. Next, a gamma-corrected cumulative distribution function of the logarithmic uniform distribution approach is applied for contrast enhancement. Finally, an automated histogram expansion technique is used to redistribute the pixels of the image properly. The NM algorithm is applied to natural-contrast distorted SEM images, as well as its results are compared with six algorithms with different processing notions. To assess the quality of images, three modern metrics are utilized, in that each metric measures the quality based on unique aspects. Extensive appraisals revealed the adequate processing abilities of the NM algorithm, as it can process many images suitably and its performances outperformed many available contrast enhancement algorithms in different aspects.

Opis:
Human enhancement affects all members of society and is thus closely linked to issues of social justice: up to now, the promises and perils of enhancement are usually only known to, and thus used, by few members of society. This can lead to individual competitive advantages that create or widen social gaps. Broad public information is, therefore, key to ensure that enhancement does not conflict with the principle of equality of opportunities. As possible means of public information, literature and films are able to counter such possible social injustice, which is why they may be allotted a central role in the ethical debates on human enhancement. Two aspects will be considered in this regard: 1) enhancement in art and 2) through art. 1) The extent to which artistic depictions and public information and perceptions of enhancement may be intertwined will be illustrated by two examples where both texts and their accompanying paratexts had a particular bearing on the public debate on enhancement: the film Gattaca of 1997 and the novel Never let me go (2005) by Nobel laureate Kazuo Ishiguro. 2) The second part of the paper is dedicated to the question of how far enhancing selected groups of society may contribute to a greater common good and which potentials art can offer in this regard. Three groups of persons will be taken into account: 1) clinical ethics committees, 2) physicians, and 3) patients.

In this article I discuss one of the most significant areas of bioethical interest, which is the problem of moral enhancement. Since I claim that the crucial issue in the current debate on human bioenhancement is the problem of agency, I bring out and examine the conditions of possibility of selfunderstanding, acting subjects attributing responsible authorship for their actions to themselves. I shall argue that the very idea of moral enhancement, properly understood, fails to justify the claims that enhancing the “biological” factor that plays a part in the process of making moral choices, whether through biomedical or genetic interventions, will actually increase the probability of having “morally better future motives”.

A metamaterial in the form of a periodic lattice of split-ring resonators on a GaAs/AlGaAs heterostructure was numerically studied at terahertz frequencies. A finite-difference time-domain algorithm was applied to calculate distribution of the electromagnetic field in the layer positioned at 100 nm below the heterostructure surface where a two-dimensional electron gas typically resides in real structures. The results allowed to determine the resonant frequencies of the metamaterial as well as an enhancement factor of the electric field as a function of the period of the metamaterial's lattice.

Opis:
This paper proposes a speech enhancement method using the multi-scales and multi-thresholds of the auditory perception wavelet transform, which is suitable for a low SNR (signal to noise ratio) environment. This method achieves the goal of noise reduction according to the threshold processing of the human ear’s auditory masking effect on the auditory perception wavelet transform parameters of a speech signal. At the same time, in order to prevent high frequency loss during the process of noise suppression, we first make a voicing decision based on the speech signals. Afterwards, we process the unvoiced sound segment and the voiced sound segment according to the different thresholds and different judgments. Lastly, we perform objective and subjective tests on the enhanced speech. The results show that, compared to other spectral subtractions, our method keeps the components of unvoiced sound intact, while it suppresses the residual noise and the background noise. Thus, the enhanced speech has better clarity and intelligibility.

Opis:
Localized Surface Plasmon Resonance (LSPR) mediated electromagnetic field enhancement play a vital role in enhancing the performance of bio-molecular sensors, photovoltaic cells and Raman spectroscopy (e.g., in SERS) etc., to name only a few. It is now well established that the field amplification factor (mode squared field) ~106 for spherical shaped plasmonic nanoparticle dimers is significantly higher than the amplification factor of a monomer which is ~103. In this work, a theoretical and semi-analytical approach based on multipole spectral expansion is used to investigate the electric field enhancement in the gap region of spherical nanoparticle dimers of Al, Rh, Ag, and Au. The dimer exhibit rich spectra compared to its isolated counterpart. For example, in contrast to a monomer, the dimer spectra consists of multiple resonant peaks which can be fine tuned by varying particle size and/or inter-particle separation. Moreover, the enhancement in dimer is several orders higher than that in monomers. Rich spectral features in dimer spectra arise from the interaction between particle plasmons of constituent NPs and their hybridization, which results in the splitting of plasmonic energy levels. We carry out, systematic investigation of these systems to quantify the effect of particle size, interparticle separation and metal type (Al, Ag, Au, Rh) on electric field enhancement.

Opis:
The growing popularity of so-called cognitive enhancement technologies raises questions about their impact on the sphere of individual legal responsibility. This article examines the issue of whether, in a situation where a surgeon, prone to making a fatigue-related medical error, refuses to undergo a safe cognitive enhancement before surgery, the surgeon can be attributed liability for damages. The answer to this question is negative, however, as indicated in the article, the impossibility of attributing damages is a result of (1) the lack of professional guidelines requiring doctors to undergo cognitive enhancement; (2) the lack of scientific evidence that the use of such measures results in the elimination of fatigue and reduces the risk of error. As a result, the negative answer to the analyzed question is not determined by the solution of the model of liability for damages adopted in Polish law, but rather by the current state of research on cognitive improvement. This gives the analysis a universal character and makes it possible to relate the method adopted in it to new results of research on means of cognitive enhancement if any.

Opis:
The exponential growth of technological advancements creates an environment in which the traditionally conceived cognitive enhancement – education – must constantly redefine itself in the face of the invasive presence of A.I., the social media and various biotechnologies that strive to augment the effect-oriented performance. Whereas on the conceptual level there is a visible shift from the static to flow-modelled education, and the rising trend to invest in the skills like flexibility and creativity, not many of emerging technologies are seriously considered as educational tools. The paper looks into the varieties of cognitive enhancement within educational context. Of major concern are the already available technologies of collective intelligence and nootropics, as well as experimental dowloadable learning. I review the problems occasioned by these technologies, as well as the existing solutions, which tend to incorporate rather than exclude the possibilities of radical cognitive enhancement.

Opis:
As a result of grammaticalisation processes, within various constructions the pronoun es could establish itself as the subject of these constructions. Amongst them, verbs describing the weather constitute a rather small and semantically defined verb subclass. The es-subject is regarded as a peripheral subject realisation with an abstract meaning. Since the ‘weather’ verbs are a verb group firmly anchored in the German verb system, analogous to other constructions, their primary valence varies too. The valence enhancement, i.e. the two- or multi-digit usage, allows the ‘weather’ verbs to be used as verbs of visual perception, verbs of movement, and verba dicendi. Based on the verb regnen ‘to rain’, the article more closely examines the synchronous variability of its valence.

Opis:
Many prominent bioethicists have recently raised the question of the possibility of moral status enhancement. In this paper I discuss the arguments advanced by Nicholas Agar for the possible existence of the postpersons. I argue that in spite of the many limitations and shortcomings of Agar’s account, there are no conclusive reasons to rule out the possibility of moral status enhancement. However, if post-persons are as they are described by Agar, the fact of their possibility is less interesting and ethically relevant than it might seem. Most importantly, the account of post-persons given by Agar is rather an outcome of some implausible assumptions. I propose that Agar conflates the ethical with the scientific and dismisses the importance of phenomenology in framing our ethical outlook. Also, he seems to follow the assumption made by many utilitarian ethicists that such features as sentience and cognitive capacities have some universal relevance. This accounts for the delusion that we can view our moral attitudes from the point of view of the Universe.

Because of rapidly changing customer requirements, current company-focused measures to enhance flexibility at the supply chain level are not sufficient. Therefore, flexible supply chain performance is essential for firms aiming to fulfill service level agreements despite increasing complexity, shorter delivery times, and dynamic market demands. Therefore, we suggest imple-menting flexibility-enhancing measures within and between supply chain entities that address the particular supply chain type and its flexibility requirements. Towards this end, flexibility management must be considered as a holistic management approach. This paper presents conceptual framework that helps to identify company-internal flexibility drivers to support flexible supply chain per-formance.

As a method of training neurofeedback has proved to be effective in education and therapy of children (e.g., with ADHD, autism spectrum or specific learning disorders). However, there are no neurofeedback training protocols targeting individuals with a mild intellectual disability. Therefore, I designed a neurofeedback procedure for children with this disability; it focuses on attention span training. In this study I presented the pre-planned procedure to the child’s parent to determine whether the proposed method is feasible for work with a child with a mild intellectual disability. After learning the parents’ opinion, I indicate the possible further stages of developing a neurofeedback strategy for working with children with a mild intellectual disability. Finally, I demonstrate the future directions of research and planning of neurofeedback procedures for individuals with special needs.

Opis:
A novel speech enhancement method based on generalized sidelobe canceller (GSC) structure is presented. We show that it is possible to reduce audible speech distortions and preserve residual noise level under acoustic model uncertainties. It can be done by constraining a speech leakage power according to masking phenomena and conditional minimizing the residual noise power. We implemented the proposed approach using a simple delay-and-sum beamformer model. Finally a comparative evaluation of the selected methods is performed using objective speech quality measures. The results show that the novel method outperforms conventional one providing lower speech distortions.
Prezentowana jest nowa metoda uzdatniania mowy w oparciu o strukturę uogólnionego tłumika listków bocznych. Wykazujemy, ze możliwe jest zmniejszenie słyszalnych zniekształceń mowy przy zachowaniu stałego poziomu szumu rezydualnego, dla modeli przybliżonych środowiska akustycznego. Może to być dokonane poprzez uwarunkowanie poziomu mocy przecieku mowy zgodnie ze zjawiskiem maskowania oraz minimalizację warunkową mocy szumu rezydualnego. Proponowane podejście zaimplementowano w oparciu o prosty model beamformera opóźniająco-sumującego. Ostatecznie przeprowadzono ocenę porównawczą wybranych metod z wykorzystaniem obiektywnych miar jakości mowy. Wyniki pokazują, że nowa metoda przewyższa konwencjonalną zapewniając mniejsze zniekształcenia mowy.

The study aims at showing how the dynamics of tracer gradient accounts for the stirring mechanism produced by a periodically forced flow relevant to practical mixing operation. The numerical simulation uses the equations for the orientation and norm of the tracer gradient and an analytic model for velocity. To a large extent, the micromixer properties over different ranges of the Strouhal number are explained through the response of the tracer gradient orientation to the tilting of strain principal axes resulting from flow forcing. The analysis also reveals a rich picture of stirring as the Strouhal number is varied.

Kamm is one of the most prominent analytical philosophers in moral philosophy, known from such works as Intricate Ethics (2007). She defends the rights-based approach to ethics and is also famous from constructing multilayered moral dilemmas. The review poses methodological questions, of whether scientific-like thought experiments performed in a moral lab, and the Method of Hypothetical Cases are able to transform our ethical dilemmas and provide any solutions. In the final part of the review, the first chapter of the book on Tolstoy’s essay (The Death of Ivan Ilych) is discussed in more detail.

In this paper I undertake to analyze the way in which the arrival of HETs may influence the therapeutic relationship between the medical doctor and the patient. I begin with presenting he notion of transhumanism, insisting especially on the fact that some of the technologies that can be classified as HETs are already in use. As a result, the traditionally difficult task of defining health and a disease is becoming even more complicated. This circumstance poses the risk that medical doctors in their relationship with the patient, because of the possibilities offered by new technologies, will oscillate in their professional practice between helping the patient to recover and satisfying needs that are not justified by the considerations of health. I will try to show how the therapeutic relationship between the medical doctor and the patient may be transformed because of new technologies by using the example of IVF procedure applied to postmenopausal patients. In order to understand why the relationship between the medical doctors and their patients is so vulnerable in the context of transhumanism, I propose to re-analyze the most basic notions which help us understand the nature of the therapeutic relationship: the status of medicine as contrasted with technology, basic principles of medical ethics, the notion of a disease and an illness.

The current generation paving the path for new research marks a milestone to attain the ancient goal of improving our cognition. To date, increased prevalence of cognitive enhancers by healthy people has raised the scientific community’s attention as well as media coverage. In particular, nootropics such as piracetam promise to offer modest improvements in cognitive performance. The long-lasting impetus of this “holistic enhancer” convinced scientists as well as ethicists to discuss its potential ethical implications and future directions. Moreover, there are discrepancies in the concept of a true nootropic between pharmacology and contemporary public culture. Here, I review the ethical aspects of nootropics raised by its potential use in cognition enhancement and substantiate the epistemological commentary on the concept of nootropic.

Opis:
Until recently it was believed that Navier’s boundary condition could be given as a rigorous foundation for slip phenomena. Due to the latest measurements in the mass flow rate of a gas flowing through nano- and microchannels, several discrepancies in the mathematical modelling have been found. Thus, in the literature, the opinion persists for the Navier slip condition to be correct only under certain circumstances, particularly those restricted to the first order boundary conditions. One of many ways to eliminate this discrepancy, which is extensively employed in the contemporary literature, is to develop a variety of the so-called second order boundary conditions. This path, however, seems incorrect since it lacks consistency between the bulk stress tensor and its boundary representation. In the paper we propose to replace the classical Navier slip condition with the new, more general Navier-Stokes slip boundary condition. Instead of the usual method of consideration, the boundary condition is presented as following from the mass and momentum balances within a thin, shell-like moving layer. Owing to this, the problem of consistency between the internal and external friction in a viscous fluid is solved within the framework of new layer balances, and a proper form of constitutive relations for friction and mobility forces. Finally, the common features of the Navier, Stokes, Maxwell and Reynolds concepts of a boundary slip layer are compared and revalorized. The classifications of different mobility mechanisms, important for flows in nano-, microchannels are also discussed.

Opis:
Lean has established itself as the primordial approach to obtain operational excellence. Its simple and intuitive techniques focus on reducing lead time through continuous improvement, involving all levels of employees in the organization. However, the rate of successful implementations has remained low. This paper contributes to the understanding of continuous improvement in a Lean context, by analyzing a database of almost 10.000 improvement actions, from 85 companies, covering the time frame 2010–2018. It discusses categories of actions, their impact and cost, as well as key characteristics of the companies. It proposes an objective criterion to identify “success” and “failure” in Lean implementation and tries to link these to operational results. It is probably the first time an analysis of this magnitude on the subject has been performed.

Opis:
The proposed technique is on dual axis solar tracking system based on fuzzy control. In this proposed research solar panel will move along horizontal as well as along vertical axis according to sun’s daily movement and also follow its seasonal change in axis; motion of the panel will be determined by the fuzzy controller. The proposed technique is such that solar panel actually follows the motion of sun to get maximum power. Problem is the percentage of useful solar energy because it varies with time. Variation in it occurs because as we know sun keeps on moving so its incident radiation is not perpendicular to panel’s surface all along the day. It has been observed that efficiency of solar panel is about 23% -25%. Generally, PV panels are fixed along one direction due to which as the sun moves, the angle of incident insolation varies, decreasing the amount of useful solar radiation and hence could not provide maximum power, there is need of a technique which can be used to solve out this problem.

Opis:
Głównym celem artykułu jest analiza pojęcia nieśmiertelności, wpisanie go w kontekst debaty bioetycznej poświęconej pojęciu udoskonalania człowieka i przedstawienie problemów wiążących się z tymi zagadnieniami. W tekście podejmuję próbę krótkiego omówienia kwestii udoskonalania człowieka w nawiązaniu do postępu technologicznego i zarysowanego przez Harrisa programu ewolucji udoskonalającej. Następnie staram się pokazać czym dla Harrisa jest nieśmiertelność, jakie jej typy wyróżnia, dlaczego warto się nią zajmować i w jaki sposób. Wreszcie przedstawiam główne zarzuty kierowane pod adresem nieśmiertelności i to, jak Harris się im przeciwstawia. Celem pobocznym, czy raczej postulatem, jest próba zaproponowania kierunku dalszych badań zarówno nad zagadnieniem nieśmiertelności jak i w dziedzinie udoskonalania człowieka.
The main goal of this article is to analyze the notion of immortality, to place it in the context of bioethical debate over the concept of human enhancement and to present problems related to these issues. In the text, I attempt to briefly discuss the question of human enhancement in reference to the technological progress and Harris's program of enhancing evolution. Afterwards I try to show what for Harris immortality is, what types of it he distinguishes, why is it worth dealing with and how. Finally, I present the main allegations against immortality and the way Harris opposes them. A side goal, or rather a postulate, is my attempt to propose a direction for further research both on the issue of immortality and in the field of human enhancement.

Image enhancement is becoming increasingly im portant with the advancement of space exploration techniques and the technological development of more durable and sci entifically sound observatories equipped with more powerful telescopes. The enhancement of images helps astronomers an alyze the results and act toward determining the dates of religious festivals. This work describes a technique known as contrast-limited adaptive histogram equalization (CLAHE) with grayscale contrast enhancement and bilateral filtering. We apply CLAHE on the L component of the CIE-Lab color space to adjust lightness contrast. Subsequently, grayscale contrast enhancement is performed to increase the visibility of the moon crescent. Noise caused by grayscale contrast en hancement is reduced using bilateral filtering. Two quantitative measures are selected (PSNR and MSE) to show the visual improvement achieved by the proposed algorithm.

Opis:
The aim of this study was to evaluate the effect of the size of gold nanoparticles (GNPs) on dose enhancement in brachytherapy with photon emitting sources. Four photon emitting sources, 125I, 169Yb, 103Pd, and 192Ir were simulated and dose rate constant and radial dose functions were compared with published corresponding data for these sources. Dose enhancement factor in the presence of gold nanoparticles of 30 mg/ml concentration was calculated separately for nanoparticles with a diameter of 50, 100 and 200 nm. Gold nanoparticles were simulated precisely as nanospheres utilizing a lattice option in the MCNPX Monte Carlo code and the results were compared with those obtained with a simple model in which gold atoms are distributed uniformly in tumor volume as a simple mixture. Among the four mentioned sources, the dose enhancement related to 125I source is higher. Our results have shown that with gold nanoparticles of higher diameter, the level of dose enhancement is higher in the tested tumor. It has been also observed that the simple model overestimates the dose enhancement factor when compared with the precise model in which nanoparticles are defined according to the Monte Carlo code. In the energy range produced by the brachytherapy sources, the dose enhancement is higher when using brachytherapy sources with lower energy. Among the size range of gold nanoparticles used in medicine, it is predicted that nanoparticles with higher diameter can be more useful when are utilized in brachytherapy. It is also recommended that when calculating dose enhancements, a precise model be used for modelling of nanoparticles in the Monte Carlo simulations.

Opis:
The presence of high Z material adjacent to soft tissue, when submitted to irradiation, enhances locally the absorbed dose in these soft tissues. Such an effect occurs due to the outscattering of photoelectrons from the high Z material. Polymer gel (PG) dosimeters were used to investigate this effect. Analytic calculations to estimate the dose enhancement were performed. Samples containing a polymer gel with 0.005 gAu/gPG and a pure polymer gel were irradiated using an X-ray beam produced by 150 kV, filtered with 4 mm Al and 5 mm Cu, which resulted in an approximately 20% greater absorbed dose in the samples with gold in comparison to those with the pure polymer gel. The analytic calculations resulted in a dose enhancement factor of approximately 30% for the gold concentration of 0.005 gAu/gPG.

The paper presents the results of sentence and logatome speech intelligibility measured in rooms with induction loop for hearing aid users. Two rooms with different acoustic parameters were chosen. Twenty two subjects with mild, moderate and severe hearing impairment using hearing aids took part in the experiment. The intelligibility tests composed of sentences or logatomes were presented to the subjects at fixed measurement points of an enclosure. It was shown that a sentence test is more useful tool for speech intelligibility measurements in a room than logatome test. It was also shown that induction loop is very efficient system at improving speech intelligibility. Additionally, the questionnaire data showed that induction loop, apart from improving speech intelligibility, increased a subject’s general satisfaction with speech perception.

Reverberation is a common problem for many speech technologies, such as automatic speech recogni- tion (ASR) systems. This paper investigates the novel combination of precedence, binaural and statistical independence cues for enhancing reverberant speech, prior to ASR, under these adverse acoustical con- ditions when two microphone signals are available. Results of the enhancement are evaluated in terms of relevant signal measures and accuracy for both English and Polish ASR tasks. These show inconsistencies between the signal and recognition measures, although in recognition the proposed method consistently outperforms all other combinations and the spectral-subtraction baseline.

This study analysed the theoretical foundations utilised by past empirical research in order to understand the pedagogical strategies used in schools for promoting positive behaviour. The analyses also include how pedagogical theories underpinned past research on positive behaviour enhancement. Samples for this study were academic papers obtained from four main databases: the Australian Education Index, British Education Index, ERIC (Educational Research Information Centre) and Scopus. By using a systematic review technique, a total number of 143 papers were found to be relevant for further analysis. Results revealed that four theoretical models dominate the studies examined, namely Applied Behavioural Analysis, Social Capital theory, Culturally Responsive Classroom Management, and Ecological Systems theory. This study recommends understanding of those theories is important in designing modules for positive behaviour enhancement in schools.

Zabiegi intensyfikacji wydobycia wpływają znacząco na własności fizyczne strefy przyodwiertowej, zwiększając przez to produktywność odwiertu. Efektywność takich zabiegów ocenić można przez analizę podstawowych parametrów eksploatacyjnych oraz porównanie zdolności produkcyjnej przed zabiegiem i po nim. W większości przypadków zabiegi te oceniane są jako pozytywne, jako że znacząco wpływają na wydobycie z odwiertów. Jednakże uwzględnienie czynnika ekonomicznego oraz czasu trwania efektu zwiększenia produktywności może zmienić te oceny. Wynika stąd konieczność gromadzenia i analizy dodatkowych danych eksploatacyjnych. W artykule dokonano przykładowych ocen efektywności zabiegów intensyfikacyjnych z uwzględnieniem wymienionych czynników oraz określono progi opłacalności ekonomicznej
Enhancement procedures significantly influence the physical properties of the near-hole zone, thus increasing its productivity. The efficiency of such procedures can be evaluated by analyzing basic exploitation parameters and comparing them with productivity before and after the enhancement. In a majority of cases, these procedures are assessed as positive, significantly improving the productivity of wells. However, the economic factor may change the final evaluation. Hence a conclusion that additional exploitation data should be gathered and analysed. Exemplary assessments of enhancement efficiency are presented. The above mentioned factors were accounted for and economic profitability established

We propose a high-quality infrared and visible image fusion method based on a deep wavelet-dense network (WT-DenseNet). The WT-DenseNet includes three network layers, the hybrid feature extraction layer, fusion layer, and image reconstruction layer. The hybrid feature extraction layer is composed of a wavelet and dense network. The wavelet network decomposes the feature map of the visible and infrared images into low-frequency and high-frequency components, respectively. The dense network extracts the salient features. A fusion layer is designed to integrate low-frequency and salient features. Finally, the fusion images are outputted by an image reconstruction layer. The experimental results demonstrate that the proposed method can realize high-quality infrared and visible image fusions, and the performance of the proposed method is better than that of the six recently published fusion methods in terms of contrast and detail performance.

Opis:
Speech enhancement in strong noise condition is a challenging problem. Low-rank and sparse matrix decomposition (LSMD) theory has been applied to speech enhancement recently and good performance was obtained. Existing LSMD algorithms consider each frame as an individual observation. However, real-world speeches usually have a temporal structure, and their acoustic characteristics vary slowly as a function of time. In this paper, we propose a temporal continuity constrained low-rank sparse matrix decomposition (TCCLSMD) based speech enhancement method. In this method, speech separation is formulated as a TCCLSMD problem and temporal continuity constraints are imposed in the LSMD process. We develop an alternative optimisation algorithm for noisy spectrogram decomposition. By means of TCCLSMD, the recovery speech spectrogram is more consistent with the structure of the clean speech spectrogram, and it can lead to more stable and reasonable results than the existing LSMD algorithm. Experiments with various types of noises show the proposed algorithm can achieve a better performance than traditional speech enhancement algorithms, in terms of yielding less residual noise and lower speech distortion.

Opis:
The prior language knowledge of learners for whom the target language is not the first foreign language poses a different starting learning situation that should merit pedagogical attention. The present paper seeks to contribute to the question of which pedagogical considerations can be made in regard to the role of prior language knowledge beyond instructed L2 grammar acquisition. Moreover, it fills a significant gap expanding the limited existing pedagogical options that instructors have at their disposal when it comes to teaching in classrooms where one foreign language is simultaneously chronologically first to some and second to others. Starting with (combinations of) existing theoretical accounts and associated pedagogical aspects (such as explicit information, negative evidence, metalinguistic explanations, grammar consciousness raising, and input enhancement), a recently developed method (Hahn & Angelovska, 2017) is discussed. The method acknowledges equally the three phases of input, practice and output and is applicable in instructed L2 grammar acquisition and beyond.

Opis:
Rosnące zapotrzebowanie na surowce energetyczne, a w szczególności na ropę naftową oraz wiążący się z tym wzrost cen paliw na światowym rynku wymusza na firmach eksploatacyjnych poszukiwania nowych rozwiązań. Jednym z nich jest konieczność wzmożenia intensyfikacji wydobycia surowców z istniejących już starych odwiertów. Niestety, często z uwagi na zły stan konstrukcji lub spadek wydobycia otwory takie wymagają prac rekonstrukcyjnych. Ponieważ prace rekonstrukcyjne są pracami o podwyższonym ryzyku (obecność medium pod ciśnieniem, duże zużycie elementów wyposażenia zarówno napowierzchniowego jak i wgłębnego), niezbędna jest znajomość najnowszych rozwiązań technicznych stosowanych do rekonstrukcji lub powierzenie tych prac wyspecjalizowanym firmom. W artykule autorzy analizują siły, jakie działają podczas prac z użyciem elastycznego przewodu - coiled tubingu.
The growing demand for energy minerals, especially oil, and the resulting growth of world's fuel prices induces on prospecting companies elaboration of new solutions. One of them is the necessity of intensifying raw minerals in the existing wells. Unfortunately, owing to the bad technical condition of the well or drop of production, the wells need reconstruction works. The reconstruction works are high-risk operations (presence of pressurized medium, high wear of the surface and downhole equipment), therefore it is vital to know the newest reconstruction solutions or to ordering them at specialized companies. The forces acting during works with a coiled tubing are analyzed in the paper.

Opis:
The aim of this study is the evaluation of electron dose enhancement and photon contamination production by various nanoparticles in the electron mode of a medical linac. MCNPX Monte Carlo code was used for simulation of Siemens Primus linac as well as a phantom and a tumor loaded with nanoparticles. Electron dose enhancement by Au, Ag, I and Fe2O3 nanoparticles of 7, 18 and 30 mg/ml concentrations for 8, 12 and 14 MeV electrons was calculated. The increase in photon contamination due to the presence of the nanoparticles was evaluated as well. The above effects were evaluated for 500 keV and 10 keV energy cut-offs defined for electrons and photons. For 500 keV energy cut-off, there was no significant electron dose enhancement. However, for 10 keV energy cut-off, a maximum electron dose enhancement factor of 1.08 was observed for 30 mg/ml of gold nanoparticles with 8 MeV electrons. An increase in photon contamination due to nanoparticles was also observed which existed mainly inside the tumor. A maximum photon dose increase factor of 1.07 was observed inside the tumor with Au nanoparticles. Nanoparticles can be used for the enhancement of electron dose in the electron mode of a linac. Lower energy electron beams, and nanoparticles with higher atomic number, can be of greater benefi t in this field. Photons originating from nanoparticles will increase the photon dose inside the tumor, and will be an additional advantage of the use of nanoparticles in radiotherapy with electron beams.

Opis:
Algorithms for examination of the density and selected parameters of movement of sperm cells have been elaborated and implemented. The conducted research is a part of work on a computer system for semen analysis. The system will allow for an increase in the precision of examination thanks to an exact specification of numerical values of the chosen parameters. An additional advantage of the system is an increased time efficiency of examination. Nowadays, the basic type of examination is an estimated analysis of semen parameters by visual observation of a sample, based on a physician's subjective assessment of an image. Registration of images is impossible in visual analysis.

Opis:
Underwater acoustic images are acquired using sonar instrument that uses sound propagation to navigate and map the sea floor. The sonar devices are effectively used to create images of large area of the seabed. However, the visual perception of the object in the acoustic image depends on refraction, which is a function of changes in the speed of sound in successive layers of water. And refraction depends mainly on temperature, slightly on salinity and hydrostatic pressure. The quality and resolution of sonar imaging of the bottom depends on many other factors such as pitch, yaw and heave of the side scan sonar, the presence of volume scatterers in the water body, the distance of the sonar from the bottom and orientation of the object. Generally, the objects in an acoustic image would be of small size compared to their normal size as the distance between the sonar and object is larger. To detect and recognize the objects in the images, the resolution should be enhanced. In this paper, we propose an efficient edge preserving interpolation method for underwater acoustic image resolution enhancement which preserves the edge sharpness. The method handles the diagonal pixels in the first pass, in turn fills the horizontal and vertical pixels in the second pass. The results obtained are compared with the state-of-the-art interpolation techniques and the performance measures such as Peak Signal to Noise Ratio (PSNR) and Structural Similarity Index Measurement (SSIM) shows an improved result.

Opis:
The effect of the linewidth enhancement factor (LEF) or α-factor on two common routes to chaos (mainly period-doubling and quasi-periodic routes) in optically injected semiconductor laser is theoretically investigated using bifurcation diagrams. The value of the LEF is slightly modified to examine the sensitivity of routes to chaos to any variation in the LEF. Despite the fact that LEF enhances chaos in the system, both routes are found to be highly insensitive to the variation in the LEF.

Opis:
Speaker‘s emotional states are recognized from speech signal with Additive white Gaussian noise (AWGN). The influence of white noise on a typical emotion recogniztion system is studied. The emotion classifier is implemented with Gaussian mixture model (GMM). A Chinese speech emotion database is used for training and testing, which includes nine emotion classes (e.g. happiness, sadness, anger, surprise, fear, anxiety, hesitation, confidence and neutral state). Two speech enhancement algorithms are introduced for improved emotion classification. In the experiments, the Gaussian mixture model is trained on the clean speech data, while tested under AWGN with various signal to noise ratios (SNRs). The emotion class model and the dimension space model are both adopted for the evaluation of the emotion recognition system. Regarding the emotion class model, the nine emotion classes are classified. Considering the dimension space model, the arousal dimension and the valence dimension are classified into positive regions or negative regions. The experimental results show that the speech enhancement algorithms constantly improve the performance of our emotion recognition system under various SNRs, and the positive emotions are more likely to be miss-classified as negative emotions under white noise environment.

Opis:
Helping behavior can be triggered by complex motivators, a number of them self-related. Investigation of this issue can foster a better understanding of such current social phenomena as volunteerism within the context of intensive migration in Europe. The research presented here focuses on individuals who applied for volunteer positions in the Registration and Reception Centers for Refugees in Bulgaria. Document analysis was conducted concerning 128 applications for participation in an ongoing volunteer project during the period 2013-2016. The explicit motivations of candidates indicate that groups of motives related to self-enhancement are among the key triggers for volunteers. These include a desire to foster social change and the effort to develop a positive self-image, both of which are associated with the role of volunteer.

Opis:
This paper proposes an enhancement approach to improve the accuracy of global Digital Elevation Models (GDEMs) in Egypt. The proposed approach is an empirical one that depends on subtracting the heights error from the original DEM. The research includes the evaluation and enhancement of SRTM-1 (SRTM v4.1), ASTER GDEM v2, and AW3D30 v2 GDEMs, in Egypt, using 980 well distributed GPS/levelling points, that cover the entire country. The GPS/levelling points are divided into 500 control and 390 check points. The results show that the root mean square error (RMSE) in the SRTM, ASTER and AW3D30 are 3.99 m, 8.81 m, and 2.98 m respectively. For enhancing purposes, two different approaches are used: a linear regression analysis approach, and the proposed empirical surface subtraction approach. The results of the linear regression analysis approach show that the accuracies are improved by 3%, 16%, and 3% for SRTM, ASTER and AW3D30 respectively. However, the accuracies are improved by 5%, 23%, and 16% for SRTM, ASTER and AW3D30 respectively when the proposed approach is followed. After using the proposed approach, the obtained accuracy of the enhanced DEM reached 2.5 m.

Opis:
The paper describes applications of the vibration-assisted laser surface texturing and spark erosion process as methods of modifying properties and structures of metal surfaces. Practical aspects of the use of produced surfaces in the heat exchanger with a minichannel have been described. Compared with smooth surfaces, developed metal surfaces obtained by vibration-assisted laser surface texturing and electromachining show more effective heat transfer. The local heat transfer coefficient for the saturated boiling region obtained for developed surfaces had the values significantly higher than those obtained for the smooth plate at the same heat flux. The experimental results are presented as the heated plate temperature (obtained from infrared thermography) and relationships between the heat transfer coefficient and the distance along the length of the minichannel for the saturated boiling region.
