MATERIAL OPTIMIZATION AND DYNAMIC MATERIALS
Authors: Lurie K.A.
Published: October 2021

The paper is about the connection between material optimization in dynamics and a novel concept of dynamic materials (DM) defined as inseparable union of a framework and the fluxes of mass, momentum, and energy existing in time dependent material formations. An example of a spatial-temporal material geometry is discussed as illustration of a DM capable of accumulating wave energy. Finding the optimal material layouts in dynamics
demonstrates conceptual difference from a similar procedure in statics. In the first case, the original constituents are distributed in space-time, whereas in the second - in space alone. The habitual understanding of a material as an isolated framework has come from statics, but a transition to dynamics brings in a new component - the fluxes of mass, momentum, and energy. Based on Noether theorem, these fluxes connect the framework with the environment into inseparable entity termed dynamic material (DM). The key role of DM is that they support controls that may purposefully change the material properties in both space and time, which is the main goal of optimization.

The English language is seen as an important medium of communication between people especially in higher institutions in Malaysia and also in the working world. Thus, a lot of effort has been put in to producing students who are competent in communicating effectively in a different social and professional context. One of the ways in enhancing students’ proficiency in English is by using Madlipz. Madlipz is an application that could be
downloaded to the handphone. The application allows students to dub their voices and create their own dialogue or monologue based on the video clips that they chose. With regards to this, this study looks into the use of MadLipz in enhancing students’ proficiency in English. Students who took Oral Communication in English were involved in this study. A mix-method approach has been applied to collect data for the purpose of the study. The
findings of this study revealed that not only has MadLipz improved students’ pronunciation in English, but the application has also improved students’ selfesteem and confidence level to speak English.
BANK LENDING BEHAVIOR: EVIDENCE FROM MALAYSIAN DUAL BANKING SYSTEM
Authors: Affandi Salwani , Ja’afar Anis Izzati , Ismail Fathiyah , Abdul Shukur Nabilah
Published: October 2021

This study investigates the internal and external factors that influence bank lending behaviors in Malaysian’s dual banking system. The final regression of 24 commercial and 15 Islamic banks using the pooled ordinary least square (POLS) method revealed that the size of the bank proxies by the logarithm of total assets as the most significant factor influencing bank lending behavior in Malaysia from 2010 to 2018. This suggests that larger banks are more diversified and have a larger pool of funds to be loaned out. Because banks rely on deposits to issue loans, the deposits received by the bank have a substantial impact on bank lending. The greater the number of deposits obtained; the more bank lending activities will occur. The data also demonstrated that commercial and Islamic bank lending behavior in Malaysia is strongly connected with deposit volume (DEPO), GDP, and bank size (SIZE).

Published: October 2021

AbstractThe practice of premature sign off on audit procedures will directly affect the quality of the audit report produced by the auditor, because if one of the steps in the audit procedure is omitted, the possibility of the auditor making wrong judgments will be higher. This study aims to empirically prove the effect of time pressure and audit risk on premature sign off behavior on audit procedures. The population of this study is the auditor in the public accounting firm in Makassar City, Indonesia. Sample selection using census sampling technique. The results of this study indicate that time pressure tends to increase their efforts to prematurely terminate audit procedures (Premature sign Off). Auditors who perceive high audit risk tend to prematurely terminate audit procedures. When the auditor determines that the materiality inherent in the audit procedure is low, there is a tendency for the auditor to ignore the audit procedure because the auditor considers that if there is a material misstatement in the implementation of the audit procedure, the value is not material so that the auditor conducts premature sign off behavior.Keywords: Audit Risk, Premature Sign Off, and Time Pressure AbstrakPraktik premature sign off atas prosedur audit, akan berpengaruh secara langsung terhadap kualitas laporan audit yang dihasilkan oleh auditor, sebab apabila salah satu langkah dalam prosedur audit dihilangkan maka kemungkinan auditor dalam membuat judgment yang salah akan semakin tinggi. Penelitian ini bertujuan untuk membuktikan secara empiris pengaruh antara time pressure dan audit risk terhadap perilaku premature sign off atas prosedur audit. Populasi dari penelitian ini adalah auditor di kantor akuntan publik yang ada di Kota Makassar, Indonesia. Pemilihan sampel menggunakan teknik sampling sensus. Hasil dari penelitian ini menunjukkan bahwa time pressure, cenderung meningkatkan usahanya untuk melakukan penghentian secara prematur prosedur audit (Premature sign Off).  Auditor yang merasakan risiko audit yang tinggi cenderung untuk melakukan penghentian secara prematur prosedur audit.   Ketika auditor menetapkan bahwa materialitas yang melekat pada prosedur audit rendah maka terdapat kecenderungan auditor untuk mengabaikan prosedur audit dikarenakanan auditor menganggap jika terdapat salah saji material pada pelaksanaan prosedur audit nilainya tidaklah material sehingga auditor melakukan perilaku premature sign off.Kata Kunci: Audit Risk, Premature Sign Off, Time Pressure

Published: October 2021

Background: Current pandemic caused by Novel coronavirus (COVID-19) causes clinical symptoms from fever to
acute respiratory distress syndrome but may remain mild or asymptomatic. To evaluate the cumulative prevalence of
SARS-CoV-2 infection in a community and know how immune response develops in the population, reliable assay alongwith RT-PCR for
detection of SARS CoV 2 antibodies is needed. Healthcare workers (HCWs) represent a high-risk population for infection with SARS-CoV-2.
Methods: We evaluated total antibodies recognizing the SARS CoV 2 receptor binding domain (S1-RBD) or the Spike protein over a period of
six months in a total of 310 healthcare workers engaged in hospital using SARS-CoV-2 Total antibody assay kit. The overall Findings:
seroprevalence found in our analysis was 41.93%. In case of males the percentage positive was found to be signicantly higher at 43.91%,
compared to females at 36.25%. Seroprevalence was signicantly higher in 50 years above age group in comparison to 20-50 years old aged
healthcare workers. The seroprevalence was higher in doctors, nursing staff and lab technicians than other healthcare professionals as 44.6%.
Conclusions: This study showed high seroprevalence of SARS-CoV-2 in healthcare workers which means remaining proportion of the
healthcare workers are still susceptible to the infection. Good compliance to infection eradication and control measures, adequate PPEs, and early
detection and isolation of healthcare workers infected with SARS-CoV-2 are mandatory to reduce the risk of SARS-CoV-2 infection
TVA-GAN: Attention Guided Generative Adversarial Network For Thermal To Visible Face Transformations
Authors: YADAV NAND , Singh Satish Kumar , Dubey Shiv Ram
Published: October 2021

In the recent advancement of machine learning
methods for realistic image generation and image translation,
Generative Adversarial Networks (GANs) play a vital role. GAN
generates novel samples that look indistinguishable from the real
images. The image translation using a generative adversarial
network refers to unsupervised learning. In this paper, we
translate the thermal images into visible images. Thermal to
Visible image translation is challenging due to the non-availability
of accurate semantic information and smooth textures. The
thermal images contain only single-channel, holding only the
images’ luminance with less feature. We develop a new Cyclic
Attention-based Generative Adversarial Network for Thermal
to Visible Face transformation (TVA-GAN) by incorporating a
new attention-based network. We use attention guidance with
a recurrent block through an Inception module to reduce the
learning space towards the optimum solution.

Published: October 2021

This paper proposes a fast and accurate solver for implicit Continuous Set Model Predictive Control for the current control loop of synchronous motor drives with input constraints, allowing for reaching the maximum voltage feasible set. The related control problem requires an iterative solver to find the optimal solution. The real-time certification of the algorithm is of paramount importance to move the technology toward industrial-scale applications.

A relevant feature of the proposed solver is that the total number of operations can be computed in the worst-case scenario. Thus, the maximum computational time is known a priori. The solver is deeply illustrated, showing its feasibility for real-time applications in the microseconds range by means of experimental tests.

The proposed method outperforms general-purpose algorithms in terms of computation time, while keeping the same accuracy.
How to synchronize an out of sync system?
Authors: Louadj Kahina , Marthon Philippe
Published: October 2021

Synchronization with other machines is one of those tasks that an intelligent machine should be able to perform. To do so, a general method of synchronization must be defined and that is the ambition of this article. For this purpose, we recall what the main concepts of systemic modelling consist of. Then we define what a Synchronization Problem is and distinguish three types of synchronization problems : predetermined (PSP), stochastic (SSP) and asymptotic (ASP). So, to find the best solution, we define three optimized synchronization problems : Optimized Predetermined Synchronization Problems , Optimized Stochastic Synchronization Problems (OSSP) and Optimized Asymptotic Synchronization Problems (OASP). A general method for solving an optimized synchronization problem and thus synchronize an out of sync system, is then given; it includes four steps : step 1, identify the synchronization functions; step 2, identify the synchronization case : predetermined, stochastic or asymptotic; step 3, select an optimization criterion and solve the optimized synchronization problem corresponding to the chosen synchronization case; step 4, find a control which permits to track the system trajectory, optimal solution of the selected optimized synchronization problem. In the next section, we present a heuristic algorithm that checks the constraints of an ASP for any initial state of the system to be synchronized. The principle of this algorithm is to pursue or track a perfectly synchronized solution. Finally, we present and solve two synchronization problems in the field of Mobile Robot Systems: a synchronized satelliteization problem and the Horse Carousel Problem. We apply to these two problems the general method given above by choosing the asymptotic synchronization case and our tracking algorithm. Simulation results show the efficiency of the method and the relevance of using a tracking algorithm.
Sparse Neural Network for horse face detection in a Smart Riding Club Biometric System
Authors: Jarraya Islem , Ouarda Wael , BenSaid Fatma , Alimi Adel
Published: October 2021

Horses and breeders need to be safe on the farm and the riding club. On account of the great value of the horse, the breeder needs to protect it from theft and disease. In this context, it is important to detect and to recognize the identity of each horse for security reasons. In fact, this paper proposes a Smart Riding Club Biometric System (SRCBS) consisting in automatically detecting and recognizing horses as well as humans. The proposed system is based on the facial biometrics for a horse and the gait biometrics for a human due to their simplicity and intuitiveness in an uncontrolled environment. The present work focuses mainly on horse face detection and recognition. Animal face detection is still extremely difficult given the fact that face textures and shapes are grossly diverse. In addition, recent detectors require a huge dataset for training and represent a huge number of parameters and layers, leading to so much training time. For resolving these problems and also for a useful detection system, this paper proposes a Sparse Neural Network (SNN) based on sparse features for horse face detection.
Different global and local features were performed to identify horses and humans for the recognition process. Due to the unavailability of horse databases, this paper presents a new benchmark for horse detection and recognition in order to evaluate our proposed system. This system achieved an average precision equal to 90% for horse face detection and a recognition rate equal to 99.89% for horse face identification.
Cooperative Selection and Communications for Internet of Everything in 6G Ultra-mMTC IoT Networks
Authors: Huang He , Hu Su
Published: October 2021

Although
Cooperative Communications (CC) already exists in 4G LTE/5G, performance
improvement is just not enough, hence, how to apply collaborative technology in
6G to achieve Internet of Everything and improve communication quality
significantly is one of most important issues. As 5G communications standard has
gradually established recently, CC has been one of most
critical communication technologies which plays a founding role on Internet of Everything
in 6G networks.
Thus, in this study we propose new 6G enabled ultra-massive Machine Type Communication (mMTC) framework
based on space-ground integrated networks, and consider that collaborative
ideology has been regarded as foundation theory which widely exists in future multiple
hybrid scenarios, such as, Cognitive-Internet of Things (C-IoT) networks, UAVs
(Unmanned Aerial Vehicles) communications, air-space-ground integrated networks,
underwater acoustic communication and so on. Besides, we discuss other key
communication technologies that are closely combined with unique communication
scenes, and elaborate critical problems that shall be solved in 6G ultra-mMTC Internet
of Everything networks. Furthermore, we discuss extreme low-complexity and fast
ultra-massive relays selection algorithm to apply in all sorts of future 6G scenarios.
At last, it is concluded that for arbitrary two communication points (source/destination
devices, sensors, relays, IoT nodes and so on), ideology of nodes selection of collaborative
communication is theory of foundation to realize and optimize communication
transmission in 6G Internet of Everything ultra-mMTC networks.

Published: October 2021

El lavado broncoalveolar (LBA) se describió hace aproximadamente 50 años, y desde ese momento se ha venido empleando cada vez con más frecuencia, llegando a ser uno de los métodos de elección para hacer el diagnóstico microbiológico de las infecciones respiratorias bajas, pues facilita la identificación de patógenos oportunistas y no oportunistas. Su uso se incrementó paralelamente con el número de pacientes inmunocomprometidos, sobre todo a causa del SIDA y los trasplantes, situaciones en las que con frecuencia los pacientes padecen infecciones pulmonares por gérmenes oportunistas. El LBA es un procedimiento seguro que permite obtener muestras que aportan información amplia de las características celulares y microbiológicas del tracto respiratorio inferior. Para garantizar su utilidad es fundamental que la recolección, transporte, almacenamiento y procesamiento de las muestras sean óptimos. El análisis de las muestras se hace por técnicas convencionales para identificación de microorganismos, como sonlas tinciones y el aislamiento en medios de cultivo, y por otros métodos tales como la inmunofluorescencia, pruebas inmunológicas para la detección de antígenos y anticuerpos, y pruebas de biología molecular. En la presente revisión, se hace una actualización sobre el procedimiento de obtención, almacenamiento y transporte de las muestras de LBA, así como de las técnicas de diagnóstico microbiológico más utilizadas para identificar los principales agentes infecciosos asociados con enfermedades del tracto respiratorio inferior.

Authors: Marchini Larissa Rodrigues , Camargo Ana Carolina de Andrade Leite de , Amoroso Lizandra
Published: October 2021

A cirurgia de castração é considerada uma das técnicas cirúrgicas mais realizadas na rotina veterinária e a idade ideal para a sua execução ainda é contraditória entre os médicos veterinários, uma vez que os estudos sobre este tema relacionados a alguns fatores, como raça e espécie, são escassos. É tida como método de contracepção, controle de zoonoses e método preventivo e terapêutico de algumas enfermidades como as afecções do sistema reprodutor. A castração pré-púbere é amplamente aplicada em diversos países, porém a literatura expõe certas consequências desta prática, como o aumento do risco de aparecimento de algumas enfermidades como afecções urogenitais, obesidade, diabetes mellitus, afecções musculoesqueléticas e neoplasmas. Assim sendo, esta revisão de literatura pretende abordar a castração pré-púbere e suas consequências com o objetivo de contribuir nas decisões dos profissionais veterinários, além de colaborar com estudos futuros.
Ivermectina e Saúde Única: reposicionamento e a preocupação com o meio ambiente
Authors: Molento Marcelo Beltrão
Published: October 2021

O descobrimento, o sucesso comercial e uso social da ivermectina (IVM) sempre foram mundialmente reconhecidos e deu aos seus autores o prêmio Nobel de Medicina/Fisiologia em 2015. Sua exclusiva ação endectocida e segurança, permitiram sua imediata integração em vários protocolos sanitários para praticamente todas as espécies animais, incluindo humanos. Entretanto, uso da IVM em larga escala e em alta frequência acarretou a seleção de parasitos resistentes. Como um produto multialvo, a IVM está sendo pesquisada, reposicionada, para atuar contra o vírus SARS-CoV-2. Os cuidados ambientais também devem ser considerados, pois a eliminação ambiental da IVM pode afetar ecossistemas aquáticos e comunidades com baixo desenvolvimento social, com pouco acesso a rede de esgoto e água tratada. A IVM pode ser considerada um dos melhores exemplos de medicamentos para atuar na Saúde Única, uma vez que tenhamos o objetivo de mitigar problemas sociais, em humanos, animais e nos ecossistemas.

A indústria da construção civil é uma atividade que consome elevado volume de recursos naturais e no cenário atual é imprescindível se preocupar com o desenvolvimento sustentável e encontrar alternativas de reaproveitamento de resíduos sólidos. Nesse contexto, a reinserção do resíduo de corte de mármore e granito (RCMG) na cadeia produtiva é uma alternativa para amenizar um sério problema ambiental, pois o consumo de rochas ornamentais vem crescendo e elevando a quantidade de resíduo produzido. Devido ao grande volume de resíduos de corte de granito produzido e não reutilizado, este artigo técnico avalia a viabilidade técnica da sua utilização como adição em concretos e produção de blocos intertravados com resistência à compressão mínima de 35 MPa e a absorção d’água de 6% no máximo. As matérias primas foram caracterizadas quanto à massa específica, massa unitária, distribuição do tamanho de partículas, materiais pulverulentos e composição química (FRX). Em seguida, os corpos de prova foram moldados de acordo com as prescrições da norma técnica NBR 9781:2013 e foram realizadas análises de desempenho mecânico (resistência à compressão) e absorção d’água. Em suma, a partir dos resultados obtidos no programa experimental, o uso do resíduo de corte de mármore e granito como adição em concretos para produção de pisos de pavimentação é viável tecnicamente para tráfego de pedestres, veículos leves e veículos comerciais de linha.

Предложены асимптотические разложения для потенциала скорости, на основе которых выводятся асимптотические уравнения газовой динамики для безвихревых изоэнтропических течений идеального газа: уравнение линейной теории, нелинейное уравнение для сверхзвуковых течений, нелинейное трансзвуковое уравнение. Построены некоторые точные частные решения асимптотического нелинейного трансзвукового уравнения, учитывающего поперечные по отношению к основному потоку возмущения. На основе линейного асимптотического уравнения исследуется динамическая устойчивость упругого деформируемого элемента канала при дозвуковой скорости потока газа или жидкости. Исследование устойчивости проводится в постановке, соответствующей малым возмущениям однородного потока и малым деформациям упругого элемента, и основано на построении положительно определенного функционала, при этом получены достаточные условия устойчивости.

Published: October 2021

Рассмотрена периодическая краевая задача для одного уравнения с отклоняющимся пространственным аргументом. Данное уравнение описывает фазу световой волны в световых резонаторах с распределенной обратной связью. Оптические системы такого типа используются в компьютерных технологиях и в исследовании лазерных пучков. Поставленная краевая задача рассматривалась при двух значениях пространственного отклонения. В работе рассмотрен ряд бифуркационных задач коразмерностей $1$ и $2$. Для их решения использовались такие методы исследования динамических систем, как метод нормальных форм Пуанкаре - Дюлака, метод интегральных многообразий и асимптотические формулы. Изучен вопрос об устойчивости ряда однородных состояний равновесий. Получены асимптотические формулы пространственно неоднородных решений и условия их устойчивости.

Published: October 2021

Пусть $\mathfrak{g}$ - алгебра Ли всех векторных полей Киллинга на локально однородном римановом аналитическом многообразии $M$, $\mathfrak{h}$ - ее стационарная подалгебра, $G$ - односвязная группа, порожденная алгеброй $\mathfrak{g}$, $H$ - ее подгруппа, порожденная подалгеброй $\mathfrak{h}$, $\mathfrak{z}$ - центр алгебры $\mathfrak{g}$, $\mathfrak{r}$ - ее радикал, а $[\mathfrak{g};\mathfrak{g}]$ - ее коммутант. Если $\dim(\mathfrak{h}\cap(\mathfrak{z} + [\mathfrak{g}, \mathfrak{g}] )) = \dim (\mathfrak{h} \cap [\mathfrak{g}, \mathfrak{g}])$, то $H$ замкнута в $G$. Если для любой полупростой подалгебры $\mathfrak{p}\subset\mathfrak{g}$, удовлетворяющей условию $\mathfrak{p}+\mathfrak{r}=\mathfrak{g}$, имеет место равенство $(\mathfrak{p}+\mathfrak{z})\cap\mathfrak{h} =\mathfrak{p}\cap\mathfrak{h}$, то $H$ замкнута в $G$. Изучено также аналитическое продолжение локально заданного риманова аналитического многообразия.
