Published: April 2023

Eco-driving algorithms enabled by Vehicle to Everything (V2X) communications in Connected and Automated Vehicles (CAVs) can improve fuel economy by generating an energy-efficient velocity trajectory for vehicles to follow in real time. Southwest Research Institute (SwRI) demonstrated a 7% reduction in energy consumption for fully loaded class 8 trucks using SwRI’s eco-driving algorithms. However, the impact of these schemes on vehicle emissions is not well understood. This paper details the effort of using data from SwRI’s on-road vehicle tests to measure and evaluate how eco-driving could impact emissions. Two engine and aftertreatment configurations were evaluated: a production system that meets current NOX standards and a system with advanced aftertreatment and engine technologies designed to meet low NOX 2031+ emissions standards. For the production system, eco-driving on an urban cycle resulted in a CO2 reduction of 8.4% but an increase of 18% in brake specific NOX over the baseline cycle. With the low NOX system, eco-driving achieved a similar reduction in CO2. NOX emissions increased 108% over the baseline but remained below the low NOX standard. The eco-driving cycles generated lower exhaust temperatures than the baseline cycles, which inhibited SCR catalyst performance and increased tailpipe NOX. Conversely, a port drayage cycle with eco-driving showed improvements in both CO2 and NOX emissions over the baseline. The results demonstrate that eco-driving algorithms can be a technological enabler to meet current and potential future emissions targets for heavy-duty applications.
Lubrication Effects on Automotive Steel Friction between Bending under Tension and Draw Bead Test
Authors: Shih Hua-Chu , Singh Jatinder , Ahmed Tasfia
Published: April 2023

Zinc-based electrogalvanized (EG) and hot-dip galvanized (HDGI) coatings have been widely used in automotive body-in-white components for corrosion protection. The formability of zinc coated sheet steels depends on the properties of the sheet and the interactions at the interface between the sheet and the tooling. The frictional behavior of zinc coated sheet steels is influenced by the interfacial conditions present during the forming operation. Friction behavior has also been found to deviate from test method to test method. In this study, various lubrication conditions were applied to both bending under tension (BUT) test and a draw bead simulator (DBS) test for friction evaluations. Two different zinc coated steels; electrogalvanized (EG) and hot-dip galvanized (HDGI) were included in the study. In addition to the coated steels, a non-coated cold roll steel was also included for comparison purpose. The results revealed that the non-coated cold roll steel has the highest friction coefficient, and the HDGI has the lowest among test steels. Extra lubricant tends to increase the friction coefficient for the GI steel, and similar trend was also found for EG in the draw bead test. Well, there is a transition point found for each test steel where the friction behavior tends to be stabilized after the lubricant amount reaching the transition point. Bend under tension test tends to deliver a slightly lower friction than the draw bead test which is associated with higher surface coating deformation.

Published: April 2023

Accurate tire pressure monitoring system (TPMS) is of great practical importance and the reliability and safety of its power supply module has great concern. The piezoelectric-based surface acoustic wave (SAW) sensor is considered to have great potential in this field because of its passive, wireless and small size advantages. This paper presents the application of passive and wireless SAW sensors for real-time tire condition monitoring. The pressure sensitive structure is optimized and a three-resonator structure is also designed sensing temperature and pressure. Furthermore, a fast detection system is developed to realize high-speed signal acquisition. At last, experiments are executed and the SAW temperature and pressure sensor property is measured. The results show that the designed SAW sensor can realize real-time monitoring of tire condition; the temperature measurement range can reach -40~120°C with an accuracy of ±1°C; the pressure measurement range can reach 0~2MPa with an accuracy of 0.2MPa. This paper indicates the wireless and passive SAW temperature and pressure sensor system has the potential for application in real-time monitoring of tire condition.
Estimation of Tire-road Friction Limit with Low Lateral Excitation Requirement Using Intelligent Tire
Authors: Xu Nan , Zhou Jianfeng , Tang Zepeng , Zhang Zeyang
Published: April 2023

Tire-road friction condition is crucial to the safety of vehicle driving. The emergence of autonomous driving makes it more important to estimate the friction limit accurately and at the lowest possible excitation. In this paper, an early detection method of tire-road friction coefficient based on pneumatic trail under cornering conditions is proposed using an intelligent tire system. The previously developed intelligent tire system is based on a triaxial accelerometer mounted on the inner liner of the tire tread. The friction estimation scheme utilizes the highly sensitive nature of the pneumatic trail to the friction coefficient even in the linear region and its approximately linear relationship with the excitation level. An indicator referred as slip degree indicating the utilization of the road friction is proposed using the information of pneumatic trail, and it is used to decide whether the excitation is sufficient to adopt the friction coefficient estimate. The friction coefficient is estimated by the ratio of the normalized lateral force and the nonlinear adaptation of the slip degree. The tire forces and pneumatic trail are estimated by neural networks. The experimental validation demonstrates that the pneumatic trail has a good potential to precisely predict the friction coefficient at a low excitation under cornering conditions.
A Multibody Model for Riderless Bicycle Dynamics Considering Tire Characteristics
Authors: Cheng Kaizhuo , Duan Yupeng , Wu Jinglai , Zhang Yunqing
Published: April 2023

A multibody model for riderless bicycle dynamics considering tire characteristics is presented. A riderless bicycle is regarded as a multibody system consisting of four rigid bodies: rear wheel, frame, front fork, and front wheel. Every two bodies are connected with a revolute joint. The mass center coordinates and Euler angles of the rigid bodies are used as the generalized coordinates to describe their positions and orientations. The system equations of motion are obtained using Lagrange equations of the first kind. Due to the existence of the three revolute constraints and the use of dependent generalized coordinates, the Lagrange multipliers are employed to account for revolute reaction forces. As for the contact between the wheel and the ground, many studies regarded the wheel as a rigid body with a knife edge, which lead to the nonholonomic constraints between the wheel and the ground. However, this hypothesis may cause deviations when the bicycle travels at a high speed or takes a sharp turn. In reality, the tire is deformed due to the forces acting between the ground and the wheel which leads to the slip phenomenon and stiffness characteristic. To study the bicycle dynamics under extreme conditions better, a dynamic tire force model including the longitudinal slip, side slip, and camber force is presented. The resulting motion equations are differential-algebraic equations (DAEs) and the Baumgarte constraint stabilization method is used to solve the DAEs. Simulations according to different working conditions like accelerating and braking with tire properties are presented, where many interesting dynamic characteristics of the riderless bicycle are revealed.

Published: April 2023

Testing vision-based advanced driver assistance systems (ADAS) in a Camera-in-the-Loop (CiL) bench setup, where external visual inputs are used to stimulate the system, provides an opportunity to experiment with a wide variety of test scenarios, different types of vehicle actors, vulnerable road users, and weather conditions that may be difficult to replicate in the real world. In addition, once the CiL bench is setup and operating, experiments can be performed in less time when compared to track testing alternatives. In order to better quantify normal operating zones, track testing results were used to identify behavior corridors via a statistical methodology. After determining normal operational variability via track testing of baseline stationary surrogate vehicle and pedestrian scenarios, these operating zones were applied to screen-based testing in a CiL test setup to determine particularly challenging scenarios which might benefit from replication in a track testing environment. For this work, a Mobileye 6 aftermarket ADAS camera sensor system was tested in first a track environment and then a CiL simulation environment using Siemens Prescan. A variety of actor and environmental variables were tested, including different pedestrian and vehicle surrogates and varying levels of precipitation and atmospheric effects. From these tests, interesting scenarios in which there was a delayed or non-reaction from the camera were identified. These scenarios, in which the Mobileye system had variable performance, could be further tested in a track environment to better understand the response.
Development of a Multibody Dynamic Model of a Seated Occupant to Evaluate More Realistic ISO-Standard Motion Sickness Dose Value
Authors: Balci İbrahim , Kirli Ahmet
Published: April 2023

It is estimated that the share of autonomous vehicles in the market will reach an important point between 2050s and 2060s. Some major benefits of autonomy in ground vehicles can be regarded as reducing traffic, saving fuel and reducing emissions. Accordingly, it is anticipated that autonomous vehicles (AVs) will prevent driver error from happening, which is the primary cause of 90% of traffic accidents. However, it is a prerequisite that the AVs are accepted by the public, and be used regularly in daily life. AVs obliges everyone to be a passenger, thereby occupants will lose authority on the vehicle and have to deal with non-driving tasks during an automated ride. This will increase the lack of situational awareness, leading occupants to be more sensitive to motion sickness, where the major reasons of motion sickness are conflict between vestibular and visual senses, lack of control, unable to predict the direction of movement. Increase in motion sickness reduces comfort and can adversely affect people's attitude towards AVs. In this study, a Simscape Multibody dynamic model is developed based on a 6 DOF biodynamics model including the vertical and fore-aft motion of the whole body. The multibody model is then integrated with vestibular system dynamics to evaluate the ISO2631-1 standard motion sickness dose value (MSDV). This study aims to develop a realistic multibody simulation model to be used in comfort analyses of AVs in terms of motion sickness. This paper also demonstrates the impact of using biodynamics models in evaluating motion sickness for simulation environment. Results are quantified by using Simulink Vehicle Dynamics Blockset by comparing MSDV with and without the multibody model for several case scenarios (i.e. double lane change test, constant radius, increasing steer).
Performance and Network Architecture Options of Consolidated Object Data Service for Multi-RAT Vehicular Communication
Authors: Wippelhauser András , Chand Arpita , Datta Gupta Somak , Varadi Andras
Published: April 2023

With the proliferation of ADAS and autonomous systems, the quality and quantity of the data to be used by vehicles has become crucial. In-vehicle sensors are evolving, but their usability is limited to their field of view and detection distance. V2X communication systems solve these issues by creating a cooperative perception domain amongst road users and the infrastructure by communicating accurate, real-time information.

In this paper, we propose a novel Consolidated Object Data Service (CODS) for multi-Radio Access Technology (RAT) V2X communication. This service collects information using BSM packets from the vehicular network and perception information from infrastructure-based sensors. The service then fuses the collected data, offering the communication participants with a consolidated, deduplicated, and accurate object database. Since fusing the objects is resource intensive, this service can save in-vehicle computation costs. The combination of diverse input sources improves the object detection accuracy, which can benefit the vehicle's ADAS or autonomous driving functions.

A testbed was developed to evaluate the performance of the system under three network architectures – local RSU, Edge and the Cloud. The CODS resided in virtual machines in the corresponding three locations. The OBUs and RSU used had multi-RAT (C-V2X PC5 and 5G Uu) connectivity. A connected thermal camera was used as the infrastructure sensor in our setup.

The paper presents the performance evaluation of various CODS realizations, deployment details of the testbed on a live network and introduces our promising experimental results, explaining the trade-offs of the different deployment schemes and their effects on system fidelity and communication characteristics.

Professional secrecy of an attorney-at-law (and an attorney) and the use of instant messaging applications in the work of a professional lawyer

Practicing as an attorney-at-law (or an attorney) as a profession of public trust is associated with higher standards regarding professional deontological codes. The ratio legis of such a regulation is related to the fact of providing services of the highest possible quality and fulfilling the constitutional role related to the legal protection of citizens. In order to ensure the possibility of effective practice of the profession, the legislator provided for the institution of professional secrecy. It obliges not only state authorities not to interfere with the knowledge made available by individuals to their lawyers but also obliges attorneys-at-law (and attorneys) themselves to take all measures to protect this secrecy. Instant messaging is one of the most convenient forms of communication between a lawyer and a client. However, there are doubts about the confidentiality of the messages (and other data) sent. This article answers the question regarding the disciplinary liability of a professional attorney for the use of instant messaging to transmit information covered by professional secrecy. The author analyzed data transfer security on the basis of the two most popular messengers in Poland: Messenger and WhatsApp.

Authors: Trung Nguyen Dinh , Ping Ning , Dan Ho Kim
Published: April 2023

Mesopores of copper hexacyanoferrate (II) (M-CuHCF-II) nanomaterials used for the cesium (Cs+) removal were synthesized by the chemical coprecipitation method. M-CuHCF-II has a cubic structure (space group F-43m), a surface area of 12.80 m2/g, and a pore width of about 34.49 nm. At pH=6, the adsorption capacity of Cs+ ions by CuHCF-II reached the maximum within 15 minutes. Langmuir, Redlich–Peterson, and Sips models are suitable to describe the adsorption of Cs+ ions by M-CuHF-II materials. The maximum absorption capacity of M-CuHCF-II was determined at 318 K corresponding to the value of 197.72 mg g-1. The Gibbs free energy change (ΔG°) of Cs+ adsorption process with ranging values from -37.47 to -40.74, and ΔH0 = -8.28 (kJ mol-1) at temperatures from 298–348 K. Na+, NH4+, Ca2+, and K+ ions in solution affect the removal of Cs+ ions when they occur at high concentrations. M-CuHCF-II materials are easy to prepare, low-cost, have high adsorption capacity for Cs+ ions, and are easy to apply. In addition, the adsorption mechanism of Cs+ ions by M-CuHCF-II is also proposed and discussed.

In this study, a cerium- Metal-Organic Framework /Graphene Oxide (Ce-MOF/GO) composite material with highly efficient phosphate removal was synthesized via a solvothermal method. The physiochemical properties and removal mechanism of phosphate on composite material were analyzed by Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray diffraction (XRD), and Brunauer-Emmett-Teller (BET). The influencing parameters such as, effect of reaction time, solution pH, initial concentration, adsorbent dosage, and temperature on the adsorption capacity of the adsorbent were investigated. The kinetic and isothermal adsorption data were consistent with the pseudo-second-order model and the Langmuir adsorption isotherm model. The result shows that the maximum adsorption capacity of Ce-MOF/GO-2% composite for phosphate removal was 308. 64 mg g-1, which is higher than that of Ce-MOF. The adsorbent shows excellent reusability and after four adsorption/regeneration cycles, still maintains (92%) adsorption capacity.
Chemical extraction and quantification of extracellular polymeric substances in unspiked-metaldehyde and spiked-metaldehyde of rubber aerobic granular sludge and molasses aerobic granular sludge
Authors: Saad Azlina Mat , Dahalan Farrah Aini , Ibrahim Naimah , Yusuf Sara Yasina
Published: April 2023

The building blocks of biofilm are called extracellular polymeric substances (EPSs), and they are composed of biopolymers. The optimal properties of EPSs include chemical interactions, resistance to dehydration, and resilience in the face of hazardous shock loads. It is necessary to have an understanding of EPSs extraction, composition, and the biomatrix's reaction to contaminants. This research aims to conduct chemical extraction to determine the amounts of EPSs found in unspiked-metaldehyde and spiked-metaldehyde rubber aerobic granular sludge (rAGS) and newly invented molasses aerobic granular sludge (mAGS). The rAGS was produced by feeding synthetic wastewater into sequencing batch reactors (SBRs). The mAGS was developed by adding the rAGS with different volumes of molasses wastewater. The EPSs were successfully extracted and identified by quantifying the number of proteins and carbohydrates present in each rAGS and mAGS condition. Hydroxyl, carboxyl, and amino groups showed that rAGS and mAGS EPSs contained carbohydrates and proteins. The compositions of the EPSs showed a strong correlation with the concentrations of metaldehyde in the spiked-metaldehyde rAGS and mAGS samples. When the total EPSs are taken into consideration, both rAGS and mAGS that are formed are effective treatments for metaldehyde treatment in wastewater.

Published: April 2023

O discurso difundido pelos livros juvenis, distribuídos nas escolas públicas pelo Governo Federal, tem contribuído para o silenciamento da diversidade de gênero e sexualidade na escola. Para refletir sobre os limites desse silenciamento, analisamos três obras literárias indicadas pelo Programa Nacional do Livro Didático - PNLD Literário 2020, para as séries de 8º e 9º anos. As obras selecionadas foram: Chapeuzinho Esfarrapado e outros contos feministas do folclore mundial (2018), Extraordinárias: mulheres que revolucionaram o Brasil (2018) e Exercício de Amor (2018). Buscamos investigar em tal contexto em que medida essas literaturas contribuem ou não com o desmonte de preconceitos e estereótipos heteronormativos entre os leitores. A partir da leitura das obras realizou-se a análise das narrativas, com foco nas características das personagens e na construção e evolução dos enredos. Foram utilizadas as ferramentas dos delineamentos documental e bibliográfico, articulando-os às teorias da crítica literária numa perspectiva pós-crítica de análise. Nesse devir, sustentamo-nos teórico-metodologicamente, em especial, nos estudos de gênero de Butler (2017) e em pesquisas no campo de literaturas LGBTQIA+ de dois pesquisadores e autores: Lúcia Facco (2009) e José Silvério Trevisan (2018). Após a análise, constatamos que os enredos das obras selecionadas, descrevem homens e mulheres, meninos e meninas de muitos tipos. Todas as protagonistas, de uma maneira ou de outra, têm papéis ativos, tomam decisões, escolhem seus destinos. No entanto, apenas uma delas abordava diretamente a temática LGBTQIA+.

Considerando que os recentes estudos na área da aprendizagem da língua escrita indicam a importância da compreensão metalinguística no desenvolvimento das competências em leitura e em escrita, associado às práticas de ensino e aprendizagem da língua materna efetuadas na escola, este estudo tem por objetivo analisar as ocorrências de rasuras orais e atividades metalinguísticas efetivadas por alunos recém-alfabetizados durante tarefas de produção textual em colaboração. Vinculados aos estudos da Genética Textual, a partir de uma abordagem linguístico-enunciativa, considerou-se como unidade de análise o diálogo entre uma dupla de alunas recém-alfabetizadas ao escreverem um mesmo texto. Para isso, o percurso metodológico teve por base os registros audiovisuais da díade em processo de escritura, bem como o manuscrito escolar resultante dessa construção, preservando toda a ambientação da sala de aula. As produções de rasuras orais associadas às atividades metalinguísticas realizadas pelas crianças apontam, além dos conhecimentos já firmados pelos alunos no processo de ensino-aprendizagem, como resultados iniciais, os conhecimentos que estão sendo solidificados nesse processo de ensino de língua materna.
Bullying
Authors: Hahn Graziela
Published: April 2023

Este artigo, inscrito no campo da Linguística Aplicada, dialoga com outros campos do conhecimento e aborda, principalmente, a ideia de que a linguagem é uma forma de ação. Fundamentalmente, discuto as possíveis formas que essa ação pode assumir, abordando a violência e sua manifestação na forma do bullying. Na medida em que vemos a violência não apenas como um conceito destrutivo, procuro entender como a significação e a ressignificação dos sujeitos, através do bullying, se tornam possíveis e se delineiam a partir de uma violação do outro. De forma a esboçar a maneira danosa e violenta em que o bullying se manifesta, realizo uma análise das formas simbólicas investidas contra as vítimas, por meio das quais uma série de efeitos têm origem. Analiso, principalmente, depoimentos disponíveis em meio público digital, os quais compõem o documentário Marcas de uma geração, disponível no YouTube. Abordo os modos pelos quais diferentes sujeitos são diminuídos, depreciados, excluídos e violentados através do bullying, revelando o modo como a linguagem é utilizada para ferir o outro, especialmente aquele que representa o gênero, a raça, o corpo que não se quer aceitar. Essa discussão sobre o papel central do bullying no processo de formação do sujeito significa, no limite, que outros campos, outras abordagens críticas, além dos estudos da linguagem, deveriam incluir a questão dessa forma de violência em suas abordagens.

This is a survey paper on refrigeration monitoring systems designed using PIC microcontroller and FT811 display driver. PIC (Peripheral Interface Controllers) are a family of microcontrollers developed and produced by Microchip Technology. They are generally 8-bit or 16-bit controllers and feature a wide range of peripherals like ADCs, DACs, timers and communication interfaces. The FT811 is a graphic controller or an embedded video engine manufactured by FTDI chips. It generates images to be displayed on graphic TFT displays based on display list commands sent to it via a microcontroller through an SPI (Serial Peripheral Interface) channel. These commands can perform functions ranging from drawing lines, rectangles, displaying text and numbers, designing buttons, to loading images onto the chip’s RAM and display them on the screen. We are doing this as a part of our project as final year students belonging to the Electronics and Telecommunication branch from Pune Institute of Computer Technology.

Proper sheet metal lubrication and cleaning is essential for maintaining optimum function and life of metal parts and equipment. Lubrication reduces the risk of friction and wear, prevents damage and corrosion, and ensures smoother operation and longer life.This project deals with the Semi-Automatic Sheet Cleaning and Lubrication in washer Production. We work with semi-automatic metal sheet cleaning and lubrication systems. The system consists of a metal box in which metal sheets are stacked on top of one another. The metal sheets are the same dimensions as the ones that were previously cut out and placed in the metal box. Rollers are fixed on the top of the box for pushing the sheet metal on one side. The metal sheet are pushed through the canvas. A sponge is attached behind the rollers. As a result, the sheets are pressed against the sponge and emerge. The metal sheets were then lubricated. The sheets are now ready to be used for washer protection, just like any other industrial application. By this we are able to reduce the time and labor required.

“BASIC PROVISIONS OF PEOPLE’S MONARCHIST UNIONS” AS A STRATEGY OF NATIONAL DEVELOPMENT: ON THE QUESTION OF ASTRAKHAN RIGHTISTS’ PROPOSALS FOR THE PRESERVATION OF STATEHOOD (beginning of the 20th century)
Authors: Mikhailova Elizaveta M.
Published: April 2023

This article discusses the main provisions proposed by the Astrakhan People’s Monarchist Party in the political realities of the First World War in order to prevent a revolutionary crisis. The crisis phenomena growing in wartime conditions in the late Russian Empire required the development of a national development strategy to prevent a possible catastrophe. The Astrakhan People’s Monarchist Party, represented by the chairman N.N. Tikhanovich-Savitsky, offered the views in this direction. The document, called “Basic Provisions of the People’s Monarchist Unions”, contained the positions of the Astrakhan rightists on the main problems of the state system.

The main purpose of this study is to analyze the conceptual positions of the Astrakhan People’s Monarchist Party in the context of a rather difficult war for Russia. Materials and methods. Based on the analysis of archival stock materials and programmatic sources using historical-genetic, retrospective and problematic methods, the main directions of the positions of provincial conservative forces, which carry the paradigm of further national development, are considered.

Research results. The position of the Astrakhan People’s Monarchist Party on the issues of the system of supreme government, the role and place of elected representative institutions, in which the party, professing right-wing conservative views, connected the existence and further development of the Russian state with the preservation of autocratic power as meeting its spirit, was studied. The fundamental views of this party on the religious issue, the problems of education and upbringing, and foreign policy were studied. The proposals of the Astrakhan right in ensuring the country’s defense capability, determining the main directions of economic policy in the pre-revolutionary year are analyzed. The demands of the provincial right-wing conservatives to introduce universal conscription, ensure the country’s military-technical sovereignty, develop its own agricultural and industrial production, and expand the domestic market were seen as the basis of the country’s independence. Conclusions. The conclusion is made about the nature of the main provisions of the people’s monarchist unions proposed by the Astrakhan People’s Monarchist Party as measures to preserve the Russian statehood and national development strategy.
An Analysis of the Challenges and Prospects of Bangladeshi Manpower in Overseas Employment
Authors:   Post-Graduation from The University for the Creative Arts, London, UK, Yasmin Rumana
Published: April 2023

Since its independence, Bangladesh has supplied millions of its skilled and unskilled manpower to hundreds of countries, which, in turn, has positively influenced the domestic labour market and GDP growth. Remittances coming from migrant workers have immensely contributed to the micro and macro economy of Bangladesh. Studies show that the rising flow of overseas employment due to labour shortage in numerous developed and developing countries after the pandemic has generated both opportunities and challenges for Bangladeshi manpower. This study found that there are inflated demands for skilled and professional workers all over the world. However, Bangladesh is still unable to supply expected quality workers foreign individuals, companies and countries have demanded. The reasons behind this, our study found, are insufficient government initiatives, recruitment agencies failure, not having enough opportunity for training and education and lack of awareness among workers as well as syndicate issues and illegal migration. This study suggests that addressing the above-mentioned issues could help the respective authorities perpetuate the rising flow of foreign employment of Bangladeshi manpower.

Authors: Karunakar
Published: April 2023

A steady DC-Link Voltage, a CV voltage control and a reactive power control on the basis of the previous reviewers' analysis are the goals of the VSC-HVDC connecting controller. In order to achieve these objectives, the appropriate controller is required at both VSC-HVDC terminals. This paper presents a non-linear control approach to improve the VSC-HVDC relationship's control robustness. A sliding mode control (SMC) and an integrated proportional control (PI) were used for the configuration of a hybrid controller. The hybrid controller will provide mathematical simulation. This hybrid driver provides malfunction driving and the transient reliability of the VSC-HVDC link.  This paper presents a non-linear approach to control to improve the robustness of the VSC-HVDC controller. The hybrid controller configuration is a control of the sliding mode (SMC) and an integrated proportional control (PI) for a hybrid controller design. Fault ride the stability of this hybrid control unit is provided through and transient VSC-HVDC links. MATLAB and Simulink simulate the hybrid controller and increases the performance of the controller. The simulation induces a symmetrical grid-side malfunction to maintain transient stability.
The Effect of Rolling Temperature and Rolling Ratio on Hardness and TRS Boron Carbide 10% wt. B4C Reinforcement Copper Matrix Composite
Authors: ESKI Özkan
Published: April 2023

In this study, the effect of adding boron carbide (B4C) 10% wt. and a grain size of 90 μm on the mechanical and physical properties, such as microstructure, hardness, and density, of cold pressed copper carbide (Cu-B4C) composites was investigated. To improve the mechanical properties of commercial copper powders with a particle size of 40 μm, B4C was added with a particle size of 90 μm, 10% wt. The (Cu-B4C) composites were sintered in argon gas at 850°C for 120 minutes. Some samples were hot-rolled at temperatures (600°C,700°C,800°C) and rolling pressures (10%,20%,30%,40%) and the values obtained before and after hot rolling were compared. Where a comparison was made between density, hardness, and bending resistance, the sintered products before and after hot rolling were studied by SEM-EDS analysis. In the obtained images, it was found that B4C was homogeneously dispersed in the (Cu) matrix. The hardness of the composites increased with the increase in B4C percentage, the decrease in density, and the increase in porosity of the original samples. The hardness values of the rolled samples increased with increasing rolling temperatures (600°C,700°C,800°C) and rolling pressure ratios (10%,20%,30%,40%) and bending strength decreased with increasing rolling temperatures and pressure ratios for all samples that have been subjected to these changes.
