In this paper, we report a method for the preparation of liner paper applied on liquid crystal glass. It was obtained by wet forming of hardwood fiber and a laboratory-made hydrophilic dispersible polyester staple fiber in a certain proportion. The laboratory-made hydrophilic dispersible polyester staple fiber was obtained by co-deposition of gallic acid and ethylenediamine on PET fiber. Some additives were used in the papermaking process, including wet strength agent polyamide epichlorohydrin (PAE), anti-mildew and antibacterial agent polyhexamethylene biguanide (PHMB), and pH adjuster boric acid (H3BO3). Results showed that the liner paper has high air permeability (~35.99 μm.(Pa∙s)-1), good wet strength (~0.720 kN.m-1) and excellent anti-mildew and antibacterial properties. Interestingly, the pore size of the modified PET fiber paper increased between 23% and 29% within the same pore size range compared with PET fiber paper. This provides a theoretical basis for the relationship between paper pore size and air permeability.

Authors: Adamski Dominik , Zawadka Łukasz
Published: December 2022

Achieving the interoperability of the European rail system in each Member State requires many measures to standardise the adopted technical solutions and relevant regulations. However, it is likely that there may be some incompatibilities between individual subsystems, even if these subsystems are designed in accordance with standardised requirements. Interoperable rolling stock may be unable to move freely over an interoperable railway line due to some incompatibilities and differences in the versions of the installed firmware in the ETCS system devices. The article discusses the compliance tests of the proper integration of the on-board subsystem with the trackside subsystem, carried out by the Railway Research Institute.

Authors: Brodowski Dariusz , Flis Mateusz
Published: December 2022

In winter conditions, railroad turnouts are an element of railway infrastructure that is particularly vulnerable to weather conditions such as snowfall, blowing of freezing rainfall, low temperatures. To maintain them in full operability during un-favorable weather conditions turnouts heating systems are used. The basic system used for decades on European railways is the electric heating of turnouts (ETH). This system uses resistance heaters, is characterized by high energy consumption and low efficiency. Railway authorities, in many European countries, look for new solutions in the field of electric turnouts heating. In this paper experimental verification of a new ETH concept is presented. The new methodology uses contactless heaters instead of the classic ones and is based on an innovative way of heat distribution. As a reference object for the con-tactless heater, the classic ETH was used. Experimental research in real conditions were carried out at turnouts exploited in the Polish State Railways (PKP) network. The research was carried out in various weather conditions. As a part of the test, thermo-vision measurements were done, as well as measurements by thermo-couples and a melting rate was observed. In each case, comparative tests were carried out. The results were gathered, analyzed, concluded and presented in the paper. Keywords: electric turnouts heating ETH, optimization of ETH system, contactless electric turnout heating

Published: December 2022

The most widely-used active upper-limb (UL) prostheses worldwide are body-powered (BP), which is a two-century-old technology. Despite their affordability and functional benefits to users, these devices are prone to poor outcomes for many patients. Additionally, BP devices have witnessed limited improvements compared to their externally-powered counterparts. Literature indicates a strong need for appropriate prosthetic solutions for children and adolescents. Our previous work introduced a first-of-its-kind breathing-powered UL prosthesis (“Airbender”) that can overcome several limitations of the current BP systems (e.g., restricted operation space, user discomfort caused by the harness to which the cables are attached). Users can regulate their breathing, and this controllable airflow is subsequently used to power a small (purpose-built and optimised) Tesla turbine that can accurately control the opening and closing of the prosthetic hand. The current work explores device usability in children and adolescents with a UL difference (n = 15). Further, we gathered feedback, suggestions, and satisfaction levels from the study participants and their parents on breathing as a modality of controlling a prosthetic device. The collected responses and study observations were subjected to qualitative and statistical analysis. This study showcases real-world testing of a breathing-powered prosthesis and proves that UL-deficient children and adolescents can indeed operate the device (i.e., volitionally open or close) with their breathing input. The perceived level of difficulty in opening or closing the device tended to be on the ‘easy’ side. We report generally favourable feedback obtained from participants and their parents. Additionally, design suggestions and satisfaction levels concerning different device attributes help us involve the key stakeholders in co-creating and proactively developing a robust product development roadmap. This work is aligned with creating a step-change in the potential BP prosthesis options for patients in the future, propelled by a need-led approach. 
RDsLINet: A Novel Lightweight Inception Network For Respiratory Disease Classification Using Lung Sounds
Authors: Roy Arka , Satija Udit
Published: December 2022

Objective: Respiratory diseases are the world’s third leading cause of mortality. Early detection is critical in dealing with respiratory diseases as it improves the effectiveness of intervention, including treatment and reducing the spread. The main aim of this paper is to propose a novel lightweight inception network to classify wide spectrum of respiratory diseases using lung sound signals. Methods: The proposed framework consists of three stages: (a) preprocessing, (b) melspectrogram extraction and conversion into a 3-channel image, lastly (c) classification of the melspectrogram images into different pathological classes using proposed lightweight inception network, namely RDsLINet. Results: Utilizing the proposed architecture, we have achieved high classification accuracy of 96%, 99.5%, 91.6% for seven class classification, six class classification and healthy vs. asthma classification. To the best of our knowledge this is the first work on seven class respiratory disease classification using lung sounds. Whereas, our proposed network outperforms all the existing published works for six class and binary classification. Conclusion: The suggested framework makes use of deep learning methods and offers a standardized evaluation with strong categorization capabilities. In order to distinguish between a wide range of respiratory diseases, our study is a pioneering one that focuses exclusively on lung sounds. Significance: The proposed framework can be translated to real time clinical application which will facilitate the prospect of automated respiratory health screening using lung sounds.
Exploring the link between scenario theory, complexity- and compression-based learning
Authors: Rocchetta Roberto , Alexander Mey , Oliehoek F.A.
Published: December 2022

This work investigates generalization error bounds that apply to general classes of learning problems and focuses on recently observed parallels between PAC-learning bounds, like compression and complexity-based bounds, and novel error guarantees derived within Scenario theory. Scenario theory renders non-asymptotically and distributional free generalization error bounds for models trained by solving data-driven decision-making problems. Scenario bounds, like complexity-based bounds, can be derived before solving the learning problem from an indicator of the model’s expressiveness and richness or, like compression bounds, can apply to infinite Vapnik–Chervonenkis dimensional problems and on data-dependent hypothesis spaces. Relevant theorems and assumptions are reviewed and discussed, and a comparison of the quality of the bounds proposed for Support Vector Machines (SVMs) classifiers. We analyze the tightness of the bounds numerically for SVM trained on several randomized data sets from thirteen real-life classification problems. This analysis allows for a fair comparison of different approaches from both conceptual and experimental standpoints. Based on the numerical results, we argue that scenario bounds appear to be tighter in many cases and are always bounded in [0,1], hence non-vacuous, and are better in predicting the performance order for different hyper-parameter settings. This work shows that scenario bounds can be a powerful tool to support model selection, structural-risk mini 
A Novel Evaluation Method of Thermal Transient Measurement by Regularization
Authors: Zhang Yi , Evgrafov Anton , Zhao Shuai
Published: December 2022

In this paper we propose a new evaluation method for revealing the inner structure information from the measurements of the thermal transient response of semiconductor devices. In contrast with the conventional methods based on the frequency domain deconvolution, the proposed method casts the problem as a regularized least squares problem for an integral equation directly in the time domain. The regularization is selected based on the knowledge of certain physical quantities involved in the measurement. We observe that the thermal time constant spectrum produced by the proposed method tends to have a better capability of identifying two adjacent parameters. With the benchmark of the true values of the thermal networks, the structure function of the proposed method reduces the relative error by an order of magnitude. A series of simulations based on different parameters and structures verify the viability and performance of the proposed method. A proof-of-concept experiment based on a commercial power semiconductor device also validates the effectiveness of the proposed method.

Loss Characterization and Modeling of Ferroelectric Class II Multi-Layer Ceramic Capacitors in Resonant Converters
Authors: Jiang Yunlei
Published: December 2022

Class II multi-layer ceramic capacitors (MLCCs) employing ferroelectric materials have been widely utilized as the primary energy storage and transfer element in high-frequency resonant converters due to their ultra-high energy density. In these applications, MLCCs experience large-signal and high-frequency electrical excitations superimposed on biased voltages, burdening converters' efficiency due to their significant power loss. However, little has been published to reveal the large-signal loss characteristics of Class II MLCCs under such realistic operating conditions. This paper develops a novel characterization method to experimentally extract MLCC power loss using a resonant-Sawyer-Tower (Res-ST) circuit under large-signal and wide-frequency-range excitation with DC bias voltage. A general loss modeling approach based on Steinmetz’s Pre-electricized Graph (SPeG) is also proposed to accurately correlate the large excitation amplitude, wide-range frequency, and DC bias voltage. In this paper, the SpeG model first provides the material-specific volume loss density of four common dielectric materials and then can be easily extrapolated to evaluate the loss of the MLCCs with different rated voltage$\&$capacitance but employing the same dielectric material. In order to extend the material-specific SPeG model to device-level application, this paper also prepares an easy-to-follow tool, dielectric thickness observer (DTO), to estimate the dielectric microstructural geometry by tracking the $C$-$V$ characteristics provided in the product datasheet. The combination of the proposed loss characterization method, SPeG model, and DTO can be used as a very convenient and accurate tool to estimate the power loss of MLCCs in different applications, in particular high-frequency resonant tanks. This article is accompanied by SEM images and MATLAB code demonstrating the effectiveness of the proposed DTO.

Dados abertos têm sua relevância reconhecida mundialmente em diferentes setores para maior transparência, controle social, eficiência de serviços, inovação e crescimento econômico, com grande potencial na área de saúde pública. No Brasil, a Política Nacional de Dados Abertos (PNDA) busca contribuir para que esses benefícios sejam alcançados, porém ainda há dificuldades em sua implantação, de modo que os dados publicados pelas instituições públicas não atendem a todos os princípios para serem considerados abertos. Com este estudo, buscou-se analisar o grau de alinhamento da Empresa Brasileira de Serviços Hospitalares (Ebserh) e de sua rede de hospitais universitários federais aos princípios da PNDA. O levantamento dos dados abertos pelas 39 unidades da rede Ebserh foi realizado no portal Gov.Br, registrando os tipos de dados e suas características. O grau de alinhamento da rede Ebserh aos princípios de dados abertos foi calculado de acordo com a pontuação obtida pelas unidades avaliadas nas questões definidas segundo a PNDA. Verificou-se que somente 21 das unidades da rede Ebserh (51%) publicam dados abertos, totalizando 854 conjuntos de dados. O grau de alinhamento identificado foi de 35%, considerando toda a rede Ebserh, e de 67%, considerando somente as unidades da rede que publicam dados abertos. Observa-se que as unidades da rede Ebserh encontram-se em níveis de maturidade distintos quanto à abertura de dados, sendo que nenhuma unidade atende a todos os princípios PNDA, o que pode dificultar a busca, reutilização e interoperabilidade dos dados. A qualidade dos dados abertos da rede precisa ser melhorada para que possam, de fato, serem úteis para diferentes propósitos de reuso. Aponta-se para a importância do reconhecimento dos dados como um ativo estratégico na rede Ebserh, do clareamento das questões quanto à Lei Geral de Proteção de Dados Pessoais e do estabelecimento de uma política de governança de dados.

Published: December 2022

O Lodo de Estação de Tratamento de Água (LETA) é um resíduo descartado usualmente de forma irregular e sem tratamento adequado. Em busca de alternativas para esse problema, objetivou-se a produção e a caracterização de um material adsorvente (MA), e nesse processo o LETA, seco e pulverizado, foi ativado por processo físico e químico. A DRX mostrou a presença das fases caulinita e quartzo e, após a ativação, apenas o quartzo. Por MEV observou-se uma superfície rugosa com elevada área superficial e distribuição irregular do tamanho dos grânulos. A EDS e a EDX confirmaram composição por SiO2, Al2O3 e compostos de carbono. Por meio do estudo de pHPCZ verificou-se que o valor do pH com carga neutra é 6,15, podendo ser manipulado para que a superfície fique carregada com cargas positivas ou negativas, promovendo a adsorção de compostos catiônicos e aniônicos. Conclui-se que as mudanças promovidas no LETA foram significativas para seu uso como material precursor de adsorvente.

Uma das formas utilizadas no tratamento do lixiviado de aterro sanitário é o cotratamento com esgoto em ETEs. No país, muitas estações utilizam reatores anaeróbios (ex: UASB), que produzem biogás, que pode ser utilizado para produção de energia elétrica. Sergipe dispõe de um aterro sanitário que envia o seu lixiviado para uma central de tratamento de efluentes na Bahia. O presente trabalho analisa a viabilidade econômica de implantação de sistemas de aproveitamento de biogás em ETEs sergipanas já equipadas com reatores UASB, adicionando-se o lixiviado ao esgoto. Avaliaram-se proporções de adição de lixiviado entre 0,5% e 5%, utilizando o software ProBio 1.0 para estimar a geração de biogás para cada uma das proporções e o potencial energético em cada uma das estações. Determinou-se a economia mensal com a energia gerada pelo uso do biogás. Na análise econômica, os VPLs dos investimentos foram determinados para um horizonte de 25 anos, e seus tempos de retorno foram definidos por payback descontado. A implantação do sistema de aproveitamento mostrou-se viável para três das quatros ETEs. A ERQ Sul, a ERQ Oeste e a ETE Rosa Elze, com tempos de retorno do investimento de 11 anos e 10 meses, 12 anos e 11 meses e 19 anos e 7 meses, e VPLs de
R$ 1.225.215, R$ 1.001.668 e R$ 208.732, respectivamente, para a proporção de 5% de lixiviado adicionado ao esgoto sanitário.

Authors: do Carmo Azevedo José Jefferson , Bermudez Victória , de Araújo Rodrigues Pessoa Kelly , Marinho Silva Glória Maria
Published: December 2022

A poluição dos corpos hídricos causada pela falta de tratamento de esgoto tem causado problemas ambientais, entre eles a mortandade da vida aquática e a eutrofização. Muitas tecnologias foram desenvolvidas para tratamento de águas residuárias com bons resultados, porém com custos elevados. Partindo dessa premissa, foi desenvolvido um filtro biológico aerado naturalmente, preenchido com resíduos da construção civil (fragmentos de bloco cerâmico), com porosidade de 71,40%, operando com tempo de reação (TR) de 7 dias, de baixo custo e simplicidade operacional. O objetivo desta pesquisa foi avaliar a remoção de demanda química de carbono (DQO), nitrogênio amoniacal e fósforo total no tratamento de esgoto doméstico sintético, utilizando um filtro biológico aerado naturalmente, preenchido com meio suporte submerso de elevado índice de vazios. Os resultado de remoção média para DQO foi de 76,72 ± 24,60, para amônia de 81,50 ± 2,46%, e para fósforo total de 65,92 ± 9,77%. Portanto, o sistema desenvolvido apresentou desempenho satisfatório, visto a não utilização de aeradores e uso de meio suporte sem nenhum tratamento químico.

Статья посвящена изучению влияния сезона года на активность свертывающей системы крови студенток. Анализ результатов проведенных исследований показывает, что активность системы гемостаза в зимний сезон года существенно ниже, а в летний выше по сравнению с другими периодами года. Количество тромбоцитов в крови девушек в зимний период года минимальное – 215 тыс. в мм³, а в летний сезон года максимальное – 272. В зимний сезон года у студенток определен минимальный уровень среднего объема тромбоцитов – 8,9 фл, а в летний максимальный – 10,6. Ширина распределения тромбоцитов снижается по сезонам года в последовательности лето, осень, весна и зима и достигает наименьшего уровня – 15,5 % в зимний период года. Минимальная величина тромбокрита – 0,23 % определена в зимний период года, а в летний составила – 0,29. Зимой затрачено максимальное количество времени на свертывание крови – 486 с, а летом минимальное – 384.
