Connectionist models of mind: scales and the limits of machine imitation
Authors:   Pyatigorsk State University, Baryshnikov Pavel
Published: December 2020

This paper is devoted to some generalizations of explanatory potential of connectionist approaches to theoretical problems of the philosophy of mind. Are considered both strong, and weaknesses of neural network models. Connectionism has close methodological ties with modern neurosciences and neurophilosophy. And this fact strengthens its positions, in terms of empirical naturalistic approaches. However, at the same time this direction inherits weaknesses of computational approach, and in this case all system of anticomputational critical arguments becomes applicable to the connectionst models of mind. The last developments in the field of deep learning gave rich empirical material for cognitive sciences. Multilayered networks, mathematical models of associative dynamics of learning, self-organizing neuronets and all that allow to explain the principles of human conceptual organizing and after this to emulate these processes in computer systems. At all engineering achievements of this technology there is a traditional criticism from representatives of cognitive psychology who cannot accept a thesis about learning ability of a neuronet on the basis of redistribution of scales. Process of learning of natural intelligence, according to cognitive models, happens due to attraction of knowledge broadcast in a symbolical form (mental representations, concepts) at the expense of the systems of output knowledge expressed in the propositional contents. Some philosophical aspects of «neural metaphor» in modern cognitive sciences create the problem field which demands comprehensive understanding, the first step towards which is taken in this work.
Information fatigue syndrome as a consequence of global transformation processes
Authors:   Ural Federal University, Zhilin Innokentiy
Published: December 2020

The development of new forms of cooperation between the state and citizens within the framework of the general digitalization of public administration, due to the radical restructuring of state-public interaction, taking into account compliance with the realities and new challenges that arise on the way of introducing modern information and telecommunication technologies in all spheres of public life, is characterized by several positive shifts in this area. In particular, the activities of public administration and local self-government bodies are becoming more open, transparent, as understandable as possible, and close to the usual everyday needs of individuals. However, these processes do not always allow achieving the desired effect, because they can be accompanied by a lack of constructive dialogue between the subjects and objects of management, rejection of the new realities of functioning and resistance to social changes, some negative manifestations caused by the latest social reality. At the same time, we would like to note that without exception, all stages of the historical development of mankind at the stage of their transition from one to another brought with them significant qualitative and quantitative changes in all spheres of social life, including social, every day, political, cultural and spiritual and the like, characterized by both positive shifts and negative phenomena.
Development of computer technology as a means of supporting information technologies by managing individual nodes
Authors:   Sevastopol State University, Tkachenko Kirill
Published: December 2020

Advanced computers with high accuracy and speed in interactive mode increase the flexibility of processes in terms of objective control of performance, including due to the fact that automatic control of various devices is performed based on the results of their interactions with each other through communication channels. Simulation of human thinking using computers is a mechanism that can guarantee work in conditions of uncertainty. The accompanying increase in the volume of processed information makes it impossible to process it without the active use of computer technology, and, in turn, the complexity of computer tools leads to the complexity of managing them. Therefore, computer nodes must be managed. A convenient tool for managing computer nodes with the participation of an expert is obtained. To manage a computer node, you need to adjust its parameters. Adjustment of the computer node parameters should be made after and based on the analysis of information about the current functioning of the computer node. As the analysis is carried out verification of statistical hypotheses about node status. The proposed approach to the development of computer technology can be applied to the design of complex structured computer systems and networks. The paper uses analytical modeling of queuing systems and methods of nonparametric statistics. Adjusting the parameters of computer nodes allows you to improve their performance.
Image as Translation: The Ideological Implication of the Camera Obscura for Media Studies
Authors: Theophanidis Philippe
Published: December 2020

This essay relies on the historical figure of the camera obscura, as the site or place of articulation between the visible and the invisible. With the help of iconographic documents, it shows that it is not merely a process of inversion that defines the camera obscura. Indeed, a crucial spatial component is at play in the medium of the room itself: the camera is the very milieu where both an inversion and a displacement take place. From this perspective, it will appear more clearly that visibility does not stand beside or float above the invisible, but “takes place” right at its heart.
Ravishing Vancouver Circa 1948: Life Writing and the Immersive Translation of Noir Aesthetics
Authors: Ingram Susan
Published: December 2020

This article takes its cues from autobiography scholar Marlene Kadar’s expansive, archivally focused feminist approach to life writing in its examination of two exemplars of visual culture: Ivan Sayers and Claus Jahnke’s From Rationing to Ravishing: The Transformation of Women’s Fashion in the 1940s & 1950s exhibition and Stan Douglas’s innovatively staged Helen Lawrence and its sister project, the interactive app and installation, Circa 1948. It illuminates both works biographically, exploring their creators’ relation to Vancouver to better understand the resurgence of noir in Vancouver circa 2014 as a form of translation intended to make historical lessons about crime and corruption visible for those willing to see them.

Translating Art Catalogues: Theoretical and Practical Issues
Authors: Pireddu Silvia
Published: December 2020

This article addresses the translation of exhibition catalogues in the context of cross-medial communication by discussing a small corpus of multilingual texts. Multilingual art catalogues are a standardized genre, which collect academic, explanatory, and descriptive writings. These hybrid volumes pose problems related to semantic and communicative translation, terminology, specialized language, and emotive discourse by involving the visual. In a world where art is communicated with diverse media, publishers should reconsider the format of exhibition catalogues, as translation across media and languages can play a crucial role in marketing art and culture.

Compensation of property damage caused to non-participants in criminal procedure in order of rehabilitation
Authors: Muryleva-Kazak V. V.
Published: December 2020

The article discusses the issue of the legal nature of the right to compensate harm, the effectiveness of usage of the criminal procedure mechanism for its protection and the reasonableness of the inclusion of relevant in the Criminal Procedure Code of the Russian Federation.Based on the analysis of judicial practice, it is concluded that the courts have difficulties in determining the appropriate way to protect the right to compensate harm caused in the course of criminal proceedings and the delineation of competence between arbitration courts and courts of general jurisdiction, which leads to a violation of the applicants’ right to access to justice and reduces the effectiveness of judicial protection.In addition, it is concluded that the criminal procedure form is not adapted to the consideration of civil disputes on compensation for harm, the author names the impossibility of collecting lost profits as one of the factors that reduce the effectiveness of the use of the criminal procedural mechanism for protecting property rights.Based on the interpretation of the criminal procedure rules provided in the article, the author concludes that legal entities have an opportunity to use criminal procedure remedies for violated property rights in more cases than individuals, which violates the principle of equality before the law and the court. The article provides ways to solve the identified problems.

Segmentation of the Eastern Reelfoot Rift Margin: Reinterpretation of the Northeastern Reelfoot Rift Fault Geometry and Seismic Potential
Authors: Marlow Christopher , Cox Randel , Powell Christine
Published: December 2020

The eastern Reelfoot rift margin (ERRM) poses a significant seismic hazard to the city of Memphis, Tennessee, and may be capable of generating moment magnitude 7 earthquakes. The goal of this study is to refine the fault structure and geometry of the ERRM, to improve understanding of the associated seismic hazard. We apply multiple filters (e.g., reduction-to-pole and horizontal-gradient) to aeromagnetic intensity data, to visualize the magnetic signature of ERRM basement rocks. To remove ambiguity in our fault interpretations from the magnetic data, we restrict our interpretations to magnetic gradients that correspond to geologic and geophysical evidence of faulting and rank faults on a confidence scheme. From near Covington, Tennessee, to Dyersburg, Tennessee, we interpret the ERRM to be segmented into nine intersecting faults that trend northeast, north-northeast, and north-northwest (two high confidence, four intermediate confidence, and three low confidence). We calculate the moment magnitude potential of each fault based on the estimated fault length. The minimum moment magnitude potential is 6.0, and the maximum is 7.0.
Diálogos impertinentes
Authors: Said Roberto Alexandre do Carmo
Published: December 2020

Este artigo visa estudar as linhas de força do projeto intelectual de Luiz Costa Lima, a fim de analisar como sua teoria sobre a mímesis se insere no questionamento epistemológico acerca de uma filosofia da literatura, com contribuição decisiva para se examinar os modos e as condições com as quais o discurso literário pode ser pensado na modernidade. Tomo como ponto de partida o diálogo travado pelo crítico brasileiro com o pensamento pós-estruturalista, mais especificamente, os dois ensaios por ele elaborados acerca da filosofia antirrepresentacional de Gilles Deleuze. Parto da hipótese de que, tomada sob a lógica da reivindicação da diferença, entendida seja em um prisma político-cultural, seja em um prisma ontológico, independentes, mas complementares, a antropologia literária de Costa Lima não se revela um projeto isolado no cenário de pesquisas contemporâneo acerca da literatura.
O tempo conjurado
Authors: Maciel Emílio Carlos Roscoe
Published: December 2020

Leitura de “Para mascar com chiclets”, de João Cabral de Melo Neto (1998), este ensaio explora as complexidades sintáticas e figurativas do poema, tomando como ponto de partida as tensões entre a aposta anti-ilusionista da poesia moderna e as intimações antropomórficas e alucinatórias da tradição lírica ocidental. Ato contínuo, ao destacar a sutil trama de interrupções que atravessa os versos, tenta-se mostrar como, neste poema, o senso de uma clivagem insuperável separando homem e tempo se dá ver menos como enunciado explícito do que como uma estranha solução de compromisso entre resistência e abstração, prosaico e sublime, na qual o mergulho obsessivo e mecânico na pura repetição torna-se o atalho inesperado para um bizarro ritual autodestitutivo.
vida como retorta – Considerações sobre a autobiografia em O insistente inacabado, de Luiz Costa Lima
Authors: Ávila Myriam Correa de Araújo
Published: December 2020

Em O insistente inacabado (2019), Luiz Costa Lima recorrentemente explora as relações entre a biografia e a teoria, ao tratar do estabelecimento de uma Ciência da História, a partir do fim do século XVIII. No capítulo dedicado à autobiografia, não é apenas a escrita da vida que se aborda, mas também as contingências biográficas que interferem em e informam esse gênero e suas estratégias de construção. Propõe-se, portanto, neste artigo, distinguir dois elementos de sustentação das escritas do biógrafo e do autobiógrafo, ambas atravessadas pela res fictae e pela res factae: a “bio”, correspondendo ao vivido, e a “vida”, correspondente ao vivível.
Transitando pelas veredas insólitas de Rosa
Authors: Dos Santos Adilson , Fortes Rita das Graças Felix
Published: December 2020

Publicado em 2011, pela Editora Nova Fronteira, o volume de contos Antes das primeiras estórias reúne quatro contos da juventude de João Guimarães Rosa (1908-1967) publicados na revista O Cruzeiro e no diário O Jornal. Apesar de ainda não terem conquistado a devida atenção por parte da crítica especializada, os contos dessa coletânea flertam com as vertentes do insólito ficcional e evidenciam uma faceta de sua obra que será posteriormente aprimorada nas narrativas de matriz regionalista. O objetivo do presente estudo é apresentar uma leitura do conto “Chronos kai Anagke” pelo viés de uma dessas vertentes. Com base no arcabouço teórico de Tzvetan Todorov e Filipe Furtado, pretende-se demonstrar que a narrativa rosiana se enquadra no que Todorov denomina “fantástico puro”.
leitura do republicanismo na poesia Sousândrade
Authors: Carneiro Alessandra da Silva
Published: December 2020

Este artigo discute os poemas Novo Éden: Poemeto da adolescência (1888-1889), Harpa de Ouro (1888-1889) e O Guesa, O Zac (1902) com destaque ao teor político republicano que os constitui. Nessa tríade, Sousândrade constrói uma narrativa legitimadora da República brasileira apresentando-nos ao panorama da luta pela emancipação da nação livre e democrática como resultado dos esforços de dois heróis nacionais: Tiradentes e, surpreendentemente, a princesa Isabel, ambos representados como mártires cristãos defensores de um novo éden político. Vale ressaltar que esses poemas se inscrevem no momento de transição do Brasil monárquico para o republicano, marcado por disputas ideológicas de grupos políticos que tencionavam ser protagonistas da modernização da nação rumo ao século XX.
mimesis, a floresta de símbolos e o espelho da imitação
Authors: Freitas Marcus Vinicius
Published: December 2020

Este artigo analisa as condições históricas da construção da teoria da mimesis, de Luiz Costa Lima, em face do clima intelectual brasileiro nos anos 1970/1980. Estabelecendo uma distância tanto em relação ao desconstrucionismo quanto ao sociologismo, a teoria da mimesis se afirma como produção de diferença. A argumentação do artigo se desenvolve através de uma comparação do percurso teórico sobre a mimesis empreendido por Luiz Costa Lima com o de José Guilherme Merquior sobre o mesmo tema.
Luiz Costa Lima e a teoria do romance (Retorno à Poética)
Authors: Araújo Nabil
Published: December 2020

Neste artigo, analisamos criticamente o tratamento reservado à teoria do romance na obra do maior nome da teoria da literatura no Brasil, Luiz Costa Lima, mais especificamente a relação por ele estabelecida entre a “afirmação do romance” e o “controle do imaginário”, um tópico central de sua obra desde a década de 1980. Questionando a própria noção de “controle” aí em jogo, desembocamos num retorno à Poética como teoria dos gêneros do discurso, aqui estimulado pelo diálogo possível entre Mikhail Bakhtin e Hans Blumenberg, que Luiz Costa Lima encoraja em sua abordagem da teoria do romance.

Este trabalho visa refletir sobre ensaios críticos de Luiz Costa Lima em que o autor analisa o estranho lugar do intelectual brasileiro e latino-americano. Exercendo suas atividades em território pouco afeito ao cuidado detido com a escrita, com o esforço analítico e muito influenciado por expressões ligadas à oralidade e ao exagero retórico, o intelectual e o escritor que habitam os trópicos, muito comumente, situam-se como estrangeiros diante de seu objeto de trabalho e de seu próprio país. Muitas vezes assumem uma escrita relacionada à fala cotidiana visando à comunicação mais direta com o público. Iremos estabelecer análises relativas ao posicionamento de Costa Lima frente a essa questão, enfatizando os conceitos – tratados pelo autor – de improviso e auditividade. Trataremos dos livros Dispersa demanda: ensaios sobre literatura e teoria (1981), Pensando nos trópicos (1991) e Frestas: a teorização em país periférico (2013). Ao final, demonstraremos como as ideias de Costa Lima transitam entre textos sobre o pensamento brasileiro e críticas literárias. Tomaremos como exemplo análises do autor relativas à obra do poeta João Cabral de Melo Neto presentes nos ensaios “A traição consequente ou a poesia de Cabral”, do livro Lira e antilira: Mário, Drummond e Cabral (1968) e Dispersa demanda: ensaios sobre literatura e teoria (1981). Buscaremos mostrar que os estudos sobre improviso e auditividade configuram-se como importantes modelos analíticos. Os textos apresentam ricas ferramentas que nos ajudam a entender melhor a cultura e a produção literária do país.
Produktywność pracy w gospodarstwach rolnych w Polsce w zależności od ich wielkości ekonomicznej
Authors: Nowak Anna
Published: December 2020

Uzasadnienie teoretyczne: Opracowanie dotyczy problematyki produktywności pracy w gospodarstwach rolnych. Produktywność wiąże się z optymalnym wykorzystaniem zasobów gospodarstwa rolnego. Znaczenie badań nad produktywnością pracy wynika z tego, że stanowi ona jeden z warunków rozwoju i poprawy konkurencyjności przedsiębiorstw. Gospodarstwa rolne w Polsce charakteryzują się dużym zróżnicowaniem, stąd zasadne jest prowadzenie analiz ekonomicznych dla bardziej jednorodnych grup.

Cel artykułu: Ocena produktywności pracy w gospodarstwach rolnych należących do różnych klas wielkości ekonomicznej.

Metody badawcze: Badania zrealizowano na podstawie danych europejskiego systemu zbierania danych rachunkowych z gospodarstw rolnych, tj. FADN. Zakres podmiotowy badań obejmował gospodarstwa rolne w Polsce, zakres czasowy dotyczył lat 2010–2017. W analizie uwzględniono sześć klas wielkości ekonomicznej gospodarstw rolnych, wyodrębnionych w oparciu o wartość produkcji standardowej. Ocenę produktywności pracy przeprowadzono z wykorzystaniem cząstkowych wskaźników produktywności.

Główne wnioski: Badania wykazały zależność produktywności pracy od wielkości ekonomicznej gospodarstw rolnych. W klasach od 1 do 5 we wszystkich badanych latach miał miejsce wzrost produktywności wraz z przechodzeniem do coraz wyższej klasy. W gospodarstwach najsilniejszych ekonomicznie produktywność pracy była niższa niż w klasie 5. Należy to tłumaczyć większym udziałem mniej intensywnych upraw w strukturze zasiewów tej grupy gospodarstw. Wykazano, że gospodarstwa najsłabsze ekonomicznie, tj. wytwarzające od 2 do 8 tys. euro produkcji standardowej, osiągały najniższy poziom produktywności pracy. W 2017 r. stanowiła ona zaledwie 23,7% średniego jej poziomu dla całej populacji badanych gospodarstw rolnych. Oznacza to, że siła ekonomiczna gospodarstw determinowała efektywność wykorzystania czynnika pracy. Badania potwierdziły również związek poziomu produktywności pracy z poziomem jej technicznego uzbrojenia. Wskazuje to z jednej strony na potrzebę optymalizacji zasobów pracy w rolnictwie, z drugiej zaś na konieczność procesów modernizacyjnych. Przeprowadzone badania stanowią podstawę do dalszych badań, które powinny uwzględniać większy zakres determinant poprawy efektywności wykorzystania czynnika pracy.

Authors:   Department of Engineering (Electrical & Computer), Texas Southern University, Texas 77004, USA, Ajofoyinbo Abayomi , Olowokere David O. , Ibidapo-Obe Oye
Published: December 2020

The paper presents N-element switchable beam antennas (BAs) system design for Wireless Sensor Node (WSN), in which the operation of the BAs was characterized by semi-Markov Decision Process (SMDP) with variable sojourn time. A matrix-based switching methodology was introduced for selecting an operational BA, based on the received signal power by each BA. Optimal analysis was carried-out to obtain optimal results in terms of the maximum total of sum of discounted reward in current states. Also developed in the study is the methodology for switching a BA from non-operational to operational state and vice-versa. The effectiveness of this switchable BAs system design was tested via numerical analysis implemented in MATLAB software. Numerical results show that this novel approach enables the WSN equipped with BAs to select and maintain an operational BA in receive (or transmit) mode for the entire duration of packets reception (or transmission). The authors found no paper in the existing literature that provides this capability.
A Low-Noise Amplifier Utilizing Current-Reuse Technique and Active Shunt Feedback for MedRadio Band Applications
Authors:   School of Electrical and Electronic Engineering, Universiti Sains Malaysia, 14300 Nibong Tebal, Penang, Malaysia, Mubin Mutanizam Abdul , Marzuki Arjuna
Published: December 2020

In this work, a low-power 0.18-μm CMOS low-noise amplifier (LNA) for MedRadio applications has been designed and verified. Cadence IC5 software with Silterra’s C18G CMOS Process Design Kit were used for all design and simulation work. This LNA utilizes complementary common-source current-reuse topology and subthreshold biasing to achieve low-power operation with simultaneous high gain and low noise figure. An active shunt feedback circuit is used as input matching network to provide a suitable input return loss. For test and measurement purpose, an output buffer was designed and integrated with this LNA. Inductorless design approach of this LNA, together with the use of MOSCAPs as capacitors, help to minimize the die size. On post-layout simulations with LNA die area of 0.06 mm2 and simulated total DC power consumption of 0.5 mW, all targeted specifications are met. The simulated gain, input return loss and noise figure of this LNA are 16.3 dB, 10.1 dB and 4.9 dB respectively throughout the MedRadio frequency range. For linearity, the simulated input-referred P1dB of this LNA is -26.7 dBm while its simulated IIP3 is -18.6 dBm. Overall, the post-layout simulated performance of this proposed LNA is fairly comparable to some current state-of-the-art LNAs for MedRadio applications. The small die area of this proposed LNA is a significant improvement in comparison to those of the previously reported MedRadio LNAs.
Security Monitoring and Network Management for the Power Control Network

Published: December 2020

Security monitoring is a viable solution to enhance the security capability in the current power control Supervisory Control and Data Acquisition (SCADA) system, more broadly Industrial Control System (ICS), since the intrusion detection system as a main tool for monitoring can be easily deployed without any change of SCADA configuration. We explain how to design the SCADA domain-specific network security monitoring system, reflecting semantics of the target SCADA network. However, the attack vectors of the recent attacks to the SCADA/ICS systems are the vulnerabilities of the software underlying the host systems. In this respect, we need security monitoring running on host systems which can provide process and memory protection. Furthermore, network and system management (NMS), which incorporates the traditional network management into the power control system, can not only help to manage and maintain the IT/OT (information technology and operational technology) systems in a unified way, but also enhance the security capability of the SCADA system with collaboration with network and host security monitoring.

Published: December 2020

Many wearable or portable medical devices have limited battery energy. In this paper, a piezoelectric transducer (PZT) was adopted to take advantage of bodyweight to generate power to wearable and implantable medical devices. To confirm the power generated by the PZT, electromyography (EMG) was used to measure the subject’s muscle activity. The proposed system consists of three parts: power, measurement, and monitoring units. The power unit was tested using on 0.25 F, 0.33 F, 0.5 F, and 1 F supercapacitors to explore the best supercapacitor that can supply the measurement unit by power. Based on using PZT, we found that the power unit was able to supply the measurement unit with adequate voltage (i.e., 5 V) for normal operation without system failure. The present system has better performance than state-of-the-art in terms of power and voltage as compared to that in previous studies.

Published: December 2020

Magnetic Induction Tomography (MIT), is a promising modality used for non-invasive imaging. However, there are some critical limitations in the MIT technique, including the forward problem. In this study, a coupled multi-resolution method combining Wavelet-based Mech Free (WMF) method and Finite Element Method (FEM), short for WMF-FEM method, is proposed to solve the MIT forward problem. Results show that using the WMF-FEM method could successfully solve the mesh coordinates dependence problem in FEM, apply boundary condition in the WMF method, and increase MIT approximations. Simulations show improved results compared to the standard FEM and WFM method. The proposed coupled multi-resolution WMF-FEM method could be used in the MIT technique to solve the forward problem. The contribution of this paper is a simulated MIT system whose performance is closely predicted by mathematical models. The derivation of the simulation equations of the coupled WMF-FEM method is shown. This new approach to the forward problem in MIT has shown an increase in the accuracy in MIT approximations.
Azimuth Resolution Improvement for Squinted Synthetic Aperture Radar Imaging Based on Matched Slope Filter
Authors:   Electrical Engineering Department, Khatam al-anbia (pbuh) University, Tehran, Iran, Almaloo Farhad Sadeghi , Zarie Majid , Halili Khodadad , Khalilpour Jafar
Published: December 2020

Improving the resolution of Synthetic Aperture Radar (SAR) is a major issue that has gained significant attention recently, especially in the squint mode where obtaining high resolution is challenging. Generally speaking, the azimuth and range resolutions can be improvement by applying matched filtering for compressing the signal. Signal compression is a major part of the well-known algorithms such as the Range Doppler algorithm (RDA) and the Chirp Scaling Algorithm (CSA) by which high positioning accuracy and high resolution are obtained. The transmitted signal by SAR is most often in the form of linear frequency modulation (LFM). However, the chirp signal is always generated in the SAR azimuth direction at the receiver. The squint of observation angle of the radar makes the chirp signal non-linear and non-stationary. Consequently, this study particularly focuses on the azimuth signal compression and instead of the Matched Filter (MF) based on Fourier Transform (FT), an alternative Matched Filter is used for signal compression on time-frequency domain that is known as Matched on Slope Filter (MSF). The Matched on Slope Filter improves the effectiveness of the compression in both squint and non-squint modes. The simulation results indicate that the proposed method improves the resolution and decreases the Peak to Side Lobe Ratio (PSLR) in the target detection.

Authors:   Faculty of Science and Technology, Oita University, Oita, Japan, Haramaki Toshiyuki
Published: December 2020

In a super-aged society, medical services for health management have various problems. To solve these problems, it is desirable for all generations, including the elderly, to be self-reliant and maintain their health. In this paper, a system is proposed for everyone to actively manage their health. This system uses various contactless sensors to monitor the health of the elderly living alone and monitor and store the biometric information of the person. By comprehensively analyzing these sensor data, the system assists people and observers to easily recognize changes in the physical condition of the target person. Further, the system facilitates providing information to distant healthcare professionals when people receive medical care at home. The system prototype was created to demonstrate this mechanism. Also, the system conducts preliminary experiments and confirmed that the models and algorithms worked as expected. In the demonstration experiment, the observation target was observed using a millimeter-wave sensor and a multi-channel gas sensor, and both were integrated. As a result, the system presents changes in the observation target in detail.

Electromagnetic elimination was used to eliminate unwanted radiation that may interface with machinery or affect human health. The use of microwave absorbers has become necessary for an environment with a safe electromagnetic wave level. The objectives of this project are to design a microwave absorber as a modern biomass wall tile and to investigate the absorbing performance of the modern wall tile absorbers with different materials. The absorber was designed with similar shapes and different biomass materials. The concept of modern wall tile had been applied to design the absorbers in terms of their shape and dimension by using biomass materials. Biomass materials such as kenaf and coconut coir were used in the study due to their lightweight and environmental-friendly material behavior. The simulation was done using CST Suite Studio software to predict the preliminary result of the absorbers. The proposed designs of the modern wall tile from the CST simulation are then fabricated while the mixtures of the materials are moulded into a microwave absorber. NRL Arch free space method was used to determine the absorption performance of the modern wall tile absorbers at a frequency range from 1GHz to 12GHz. Both results of the simulation and free space measurement are analyzed and discussed. This study showed that absorber KCA has the best performance among all the absorbers with the absorption of more than -10 dB. The mixture of biomass material with carbon has a great absorption performance compared to the mixture of biomass material without carbon.

Horizontal Axis Wind Turbine (HAWT) is one of the most important devices for electricity generation from Wind Energy, and design of new blades has become a fundamental research field to improve the efficiency and to reduce cost of this system. This article presents a preliminary comparison between two micro Wind Turbines (WT), one with standard blades and another one with Wavy Leading Edge (WLE) morphology, inspired by the flippers of the humpback whale, to work at low-speed wind conditions. To perform a correct validation, the authors propose a four steps approach for the design, manufacture and test of a WT. First, the design of the blade, followed by the design of the Wind Turbine (WT). Next step is the manufacture of two functional models, one with WLE and another with standard blades, to make a relative comparison, and, finally, the acquisition of real-time data from these systems for the corresponding analysis in terms of energy generation. Results show that the WLE has an increase of over 20% in energy production in all the tests that were performed, with respect to the standard blade.

The fast depletion of conventional energy resources and the issue of global warming have encouraged researchers worldwide to come up with the best energy solution. Renewable energy resources such as wind and solar energy have been widely adopted as an alternative source of energy. In this work, an integrated solar and wind energy system were implemented aiming to produce the maximum possible output power from the available renewable energy resources such as solar irradiance and wind energy. The proposed system comprised two solar modules and horizontally rotating wind blades. An energy storage system plus a charge controller were also used aiming to improve the overall energy conversion efficiency. The results showed that this system demonstrated superior performance compared with the solar modules and wind system when they had worked individually. The proposed system was generating an average energy of 61.729 Wh daily. Therefore, it was estimated that the system can generate an annual output power of about 207.4 kWh. During the conducted experiments, the solar panels worked as the main source of the generated energy while the wind system acted as a secondary source of energy during the solar absent times. Moreover, the safety factor was calculated to be within the limits of 2 that shows the proposed system can work according to the industrial safety limits of Malaysia.

Recently, safety concerns related to electro-magnetic fields (EMFs) in inductive power transfer (IPT) systems for electric vehicles applications are pointed out. Magnetic flux concentrators are commonly used in the system to direct magnetic field lines and enhance the power transfer capability and efficiency. This article explores the performance of an IPT system for two different shapes of magnetic flux concentrators in terms of magnetic field distribution and power transmission efficiency. The dish-shape and plate-shape flux concentrators are examined and compared with a coreless IPT system. A simulation study based on three-dimensional finite-element analysis is carried out to design the magnetic couplers and analyze the IPT system’s performance. The simulation results are verified analytically and good matches are achieved.

In this research, bottom water samples were collected from nature water. After cultivating and selecting, bacteria which could use (NH4)2SO4 as the only nitrogen source had been selected. The bacteria in different cultures with different concentration of 17β-estradiol (E2) were cultivated, and every group’s concentration of N-NH4 +, N-NO3 - and OD600 were measured. The result shows that compare with the control group, in which no E2 was added, the growth of heterotrophic nitrifying bacteria had been promoted when the concentration of E2 was in range of 1-100 ng/L. In addition, heterotrophic nitrifying bacteria’s growing speed has a positive correlation between the E2’s concentration. However, low concentration of E2 (like 0.1 ng/L), could inhibit the growth of heterotrophic nitrifying bacteria. Considering the impact of E2 on heterotrophic nitrifying bacteria, it is necessary to intensify the detection to E2 in the future.

Dye wastewater produced in textile industries is a warning issue that threatens the environment due to discharge into the waterway. This study reviewed the adsorption of Methylene Blue (MB), as a toxic dye, onto diatomite adsorbent. A series of chemical modifications were examined by impregnating diatomite into various acidic and basic solutions to obtain the most active sample with the highest capacity. Both raw diatomite (RD) and modified diatomite (MD) were analyzed under different experimental conditions, such as PH, contact time, the dose of adsorbent to attain the optimum quantities of each in which adsorption capacity and removal percentage were in their highest amount. FESEM analysis indicated the surface characterization and the morphology of both adsorbents. The results of batch experiments showed that the equilibration removal capacities of MB under the optimum condition were 72 mg/g for RD and 127 mg/g for MD. Overall results suggested that due to the low-cost, naturally available, simple treatment methods and materials, and sustainability, the modified adsorbent has the potential for dye removal in the practical process.

To reduce dwelling time, special steps are needed regarding the handling speed of containers, stacking rates in container yards and management of important container documents. In 2016, the Banjarmasin Container Port (BCP) operator expanded the Container Yard area because it was considered as a step to overcome the overload in the CY area. This is proven to reduce density the following year. But along with the increasing flow of containers coming out and entering through the BCP, there could be an increase in the density of container flows. This study aims to re-evaluate and give consideration to the effect of container stacking rates on utilities and the smooth flow of goods at container Ports where new container stacking rates are beneficial for both parties (BCP operators and customers). The approach used in this study are game theory and system dynamics. System dynamics have characteristics with problems in container ports that are interrelated between one entity and another entity that has its own complexity. Game theory will give consideration to strategies that will benefit both parties if new rates are set. Based on the results, the optimal tariff is 50% (IDR 21,630) and the response decreases dwelling time for 6 days. The new tariff setting has an impact on increasing loading speed 22.09 B/C/H and unloading speed of 23.95 B/C/H. In addition, it also reduced revenue from temporary storage activities by 35.51%. While from the customer side with a 6 days response can save savings costs by 30.5%. This will help port management to make the right decision.

The kinetic sculpture is an important aspect of modern urban landscapes and installation art. However, designing such a sculpture needs much time, imagination, engineering knowledge and even rework, which restrains iterations of design and imagination of artists. To allow designers to have a holistic perspective in design, and to simplify and accelerate the design process, we proposed a system to assist designers to build kinetic sculpture digital prototypes from sketches rapidly. The system simplifies the design pipeline as sketch processing, skeleton generation, unit assignment, and motion simulation. Different from other design tools, our system liberates designers from detailed modeling and animation. Therefore, they can focus on perfecting visual effects. User cases show that our system can spark the creativity and accelerate design process both for professional and inexperienced designers, and can generalize the pipeline to other kinetic applications.
