The Pancasila Student Profile (PPP) is a translation of the national education goal from the structure of the Merdeka (freedom) curriculum which is implemented in project-based co-curricular learning activity. Public High School (SMAN) 82 Jakarta has started the PPP project for grade X (ten) of 2022 batch selecting the theme “Sustainable Lifestyle” from the available eight PPP project themes. This community service activity aims to support the implementation of the PPP that project-based in SMAN 82 Jakarta by accompanying the students to do the PPP project. One of the groups of Grade X focused on global warming’s impact on climate change as a result of using energy-consuming equipment with a case study of smartphone use among students. The experiment and observation were carried out by the student group using two brands of smartphones, namely Xiaomi Redmi Note 9 (Android-based) and Iphone 11 (IOS-based). These two smartphones were used to operate two applications, Game Online and Youtube. Each application was run for one hour using the smartphones. The result of this project demonstrates the process sequence and the calculation of how the smartphone use contributes to global warming and climate change. Furthermore, this result also gives an initial insight that no matter the smartphone brand, running the game online application will generate higher Global Warming Potential (GWP) than Youtube application. Moreover, the GWP generated from running the Youtube application depends on the smartphone brand. The result demonstrated by this PPP project activity is expected to raise awareness of global warming and climate change, particularly among students and also the general public in order to contribute in mitigation efforts through the smart use of energy-consuming equipment which is started with the equipment that always attached in our daily life, namely smartphone.
Successful detection of multiple communicating holes in multiple spinal extradural arachnoid cysts by using time-spatial labeling inversion pulse magnetic resonance imaging: illustrative case
Authors: Kagei Yusuke , Ishibe Tatsuya , Kanba Yusuke , Tanaka Masashi
Published: June 2024

BACKGROUND

Spinal extradural arachnoid cysts (SEACs) communicate with the subarachnoid space through small communicating dural holes. The precise preoperative detection of all communicating holes, followed by minimally invasive dural closure, is the ideal treatment to prevent postoperative spinal deformities, especially in cases of multiple SEACs. However, standard imaging methods often fail to detect communicating hole locations. Although a few cases of successful single-hole detection via cinematic magnetic resonance imaging (MRI) have been reported, this modality’s ability to detect multiple holes has not been demonstrated.

OBSERVATIONS

The authors describe the case of a 14-year-old male with myelopathy due to multiple SEACs at T5–8 and T8–12. Myelography revealed a complete block at the T8 level; no cephalic cyst or communicating holes were identified. Time-spatial labeling inversion pulse (T-SLIP) MRI revealed cerebrospinal fluid flow into the cyst at T10 and T7. A limited laminectomy or hemilaminectomy was performed at T7 and T10, and two dural holes were closed without a total cystectomy. The patient’s gait disturbance and rectal disorder disappeared. The cysts were confirmed to have completely disappeared on conventional MRI at 1 year postoperatively.

LESSONS

T-SLIP MRI, a cinematic MRI, is useful for detecting multiple communicating holes in SEACs.

Монография Арко ден Хейера, которая является предметом настоящей рецензии, с методологической точки зрения придерживается так называемого литературно-теологического подхода (р. 10). Цель работы — определить «лукановский образ» апостола язычников. В деталях изложение рассматривает два аспекта: с одной стороны, речи св. Павла к иудеям и язычникам с использованием нового герменевтического подхода, т. н. лингвистического концептуального контекста «исполнения» или «появления»: «Концепция «появления» обеспечит эвристические рамки для исследования и свяжет его с современным интересом к перформансу» (р. 1). По этой причине вербальные и невербальные элементы коммуникации находятся в центре рассмотрения автора. С другой стороны, образ апостола язычников объясняется ден Хейером с учетом замысла всего текста, заранее предполагая апологетическую тенденцию книги Деяний (р. 37–41).

The monograph by Arko den Heyer, which is the subject of this review, from a methodological point of view adheres to the so-called literary-theological approach (p. 10). The aim of the work is to define the ‘Lukan image’ of the apostle to the Gentiles. In detail, the presentation deals with two aspects: on the one hand, St Paul's speeches to Jews and Gentiles using a new hermeneutical approach, the so-called linguistic conceptual context of ‘fulfilment’ or ‘emergence’: ‘The concept of “emergence” will provide a heuristic framework for the study and link it to contemporary interest in performance’ (p. 1). For this reason, verbal and non-verbal elements of communication are at the centre of the author's consideration. On the other hand, the image of the apostle to the Gentiles is explained by Den Heyer with regard to the intent of the whole text, presupposing in advance the apologetic tendency of the book of Acts (p. 37-41).

IRAK TÜRK AĞIZLARINDA KULLANILAN -(y)AndA + ŞAHIS EKİ YAPISI ÜZERİNE
Authors: Doğan Talip
Published: June 2024

Eski Türkçede -DXK eki, fiil ismi ve geçmiş zaman sıfat-fiili teşkil etmiştir. -DXK ekli geçmiş zaman sıfat-fiilleri, Harezm Türkçesinde sınırlanmıştır. Kıpçak Türkçesi alanında Codex Cumanicus ile Ermeni Harfli Kıpçak Türkçesi metinlerinde de nadirdir fakat Memluk sahası metinlerinde (Oğuz Türkçesi etkisiyle) yaygındır. Çağatay Türkçesinde de -DXK ekinin kullanımı (fiil ismi ve geçmiş zaman sıfat fiili teşkili) sınırlıdır. -DXK ekinin hem fiil ismi hem de geçmiş zaman sıfat-fiili teşkil etmesi, Oğuz (Batı) Türkçesinde ise devam etmiştir. Harezm, Kıpçak ve Çağatay Türkçelerinde -GAn eki, işlev genişlemesine uğramış ve fiil isimleri ile sıfat-fiillerde -DXK ekinin işlevlerinde de kullanılmıştır.
-DXK ve -GAn ekli fiil isimleri, -DA bulunma durumu ekiyle -DXKDA ve -GAndA biçimlerinde zaman ifadeli zarf-fiil ekleri olmuştur. Tarihî Türk dili alanında -GAndA eki, -DXKDA ekinin yerine geliştirilmiştir. Bu, özellikle -DXKDA ekinin bırakıldığı Harezm, Kıpçak ve Çağatay Türkçeleri için geçerlidir. Çağdaş Türk dili alanında ise -(G)AndA eki, Karluk (Güney-Doğu), Kıpçak (Kuzey-Batı), Güney Sibirya (Kuzey-Doğu) grubunda yer alan lehçeler ile Oğuz (Güney-Batı) grubunda Türkmen, Horasan, Kaşkay, Azerbaycan (ve onun dairesine giren Irak Türk ağızları ile kimi Doğu ve Güney Doğu Anadolu Bölgesi ağızları) Türkçelerinde yer almaktadır.
Irak Türk ağızlarında -(y)AndA zarf-fiil eki, -(y)An + -dA + şahıs eki dizilişindedir. -(y)AndA zarf-fiil ekinden sonra -m, -w ~ -y, -Ø, -ḫ, -wUz ~ -yIz, -lAr biçimlerindeki iyelik kökenli şahıs ekleri kullanılmaktadır. -(y)An + -dA + şahıs eki dizilişinde ise görülen geçmiş zaman ekinin çekim paradigması örnekseme teşkil etmiştir. Söz gelişi teklik 1. şahısta: gelendem ‘(ben) geldiğimde’ ← geldim ‘(ben) geldim’ gibi.
HAMZANAME’NİN 60. CİLDİNDE YER ALAN ARKAİK KELİMELER
Authors: Sıvışan Halil İbrahim
Published: June 2024

Arkaiklik veya eskicillik terimi birçok araştırmacı tarafından açıklanmıştır. Bu terimle ilgili genel görüş, arkaikliğin herhangi bir dilin tarihî dönemlerinde aktif bir biçimde kullanıldıktan sonra kullanımdan düşmüş olan dilsel unsurları kapsaması yönündedir. Diller, canlılık işlevinden dolayı tarihî seyir içerisinde diğer dillerle sosyokültürel ve dilsel etkileşime girebilirler. Bu etkileşimlerin doğal bir sonucu olarak diller arası ses, biçim, kelime hatta söz dizimi düzeyinde alışverişler olur. Türk dilinin bu anlamdaki alışverişleri daha çok dinî terminolojiye dayanmaktadır. Nitekim; Türk dilinin yazılı belgelerle tanıklanabilen ilk dönemi olan Orhun Türkçesi Dönemi’nde, sonraki dilsel dönemlere göre daha arı bir dil kullanılmıştır. Uygur Türkçesi Dönemi’nde Maniheizm ve Budizm; Karahanlı Türkçesi Dönemi’nde ise İslam dininin benimsenmesiyle birlikte bu dinlere ait kelimeler Türk diline girmiştir. Bunun gibi birçok etkileşim dilin öz varlığını etkilemiş ve kullanımda olan kelimelerin kullanımdan düşmesine neden olmuştur. Bu kelimelerin tespiti adına Türk dilinin tarihî dönemlerinde yazılmış eserler en önemli kaynaklardır. Bu eserlerde kullanılan dil, hem dönem özelliklerini yansıtmakta hem de geçmişle olan dilsel bağları tespit etmekte kolaylıklar sağlamaktadır. Bu anlamda geçmişte birçok araştırma yapılmış ve günümüzde de yapılmaktadır. İslamî Dönem Türk Edebiyatı’nın en önemli eserlerinden birisi çalışmamıza konu olan Hamzanamelerdir. Hamzanameler, Hz. Peygamber’in amcası ve İslam’ın ilk şehitlerinden olan Hz. Hamza’nın dillere destan kahramanlıklarının anlatıldığı menkıbevî eserlerdir. Geniş bir külliyata sahip olan Hamzanameler İslamî dönemin destansı bir ürünü olmakla beraber güçlü motif yapısıyla masalsı ögelere de sahiptir. Hamzanameler, çeşitli dil özellikleri açısından Eski Anadolu Türkçesi’nin söz varlığını ve gramer özelliklerini bünyelerinde barındırırlar. Bu çalışmada, Eski Anadolu Türkçesi Dönemi’ne ait olan ve toplamda 72 cilt olarak tespit edilen Hamzanameler’in 60. cildinde yer alan arkaik kelimeler incelenmiş ve sonuç olarak 56 kelimede hem ses hem biçim hem de kelime düzeyinde arkaik (eskicil) unsurlar tespit edilmiştir. Eserin söz varlığı üzerine, eserin ikiye ayrılmasıyla yapılan yüksek lisans çalışmalarına göre eserde tekrarsız bir şekilde geçen ve çalışmaların dizininde madde başı olarak verilen 4698 kelimenin eserin yazıldığı dönem itibarı ile Arapça, Farsça ve Türkçe kelimelerden oluşturulduğu göz önüne alınırsa, kullanılan Türkçe kelimelerden sadece 56 tanesinin arkaik (eskicil) özellik taşıması eserde kullanılan Türkçenin günümüze yakın olduğuna işaret etmektedir. Çalışmada, arkaik özellikler gösteren kelimeler tespit edildikten sonra bu kelimelerin çeşitli kaynaklardaki kullanımlarına yer verilmiştir.
PİERRE BOURDİEU’NUN HABİTUS KAVRAMI BAĞLAMINDA KEMAL TAHİR’İN “NAMUSCULAR” ROMANINDA ERİL SÖYLEM
Authors: Erdal Derviş
Published: June 2024

Eril ve dişil arasındaki farklılıklar, toplumun onlara yüklediği temel davranış kalıpları sayesinde anlam bulur. Toplumun cinsiyetlere dair inşa ettiği ve içselleştirdiği rol ve statü kalıpları, eril ve dişil olanın görev ve sorumluluklarını özümsemesini sağlar. Toplumsal, bilişsel ve eylemsel süreçler, cinsiyetler arasındaki farklılıklar toplumsal alanda da meşrulaştırma gücüne sahiptir. Bu süreçler toplumun cinsiyet rollerini sürdürmesine, güç ilişkilerinin şekillenmesine ve toplum tarafından belirlenen cinsiyet hiyerarşisinin oluşumuna katkıda bulunur. Bu noktada Pierre Bourdieu’nun toplumun eril ve dişil rollerine atfettiği davranışlarıyla ilgili değerlendirmeleri önemlidir. O, cinsiyet başta olmak üzere namus gibi kavramları habitusun bir alanı olarak değerlendirir. Bourdieu’nun habitus kavramı, bu yönüyle eril tahakkümün ve toplumsal cinsiyet rollerin anlaşılmasına katkı sağlar. Ona göre birey, habitusunu oluşturan sosyal çevre içinde cinsiyetine uygun davranışlarını öğrenir ve bu normlara göre şekillenen bir habitus geliştirir. Cinsiyete yönelik söylem ve pratikler sadece sosyoloji bilimine değil, yaşamın her alanında olduğu gibi edebiyat bilimine de kaynaklık etmiştir. Edebî metinlerde yazıldığı dönemin siyasi, sosyal ve kültürel dinamiklerine yönelik izler bulabilmek mümkündür. Bu yönüyle edebî metinler, araştırmacılara önemli veriler sunmaktadır. Bu bağlamda Kemal Tahir’in cezaevi gözlemlerinden yola çıkararak kaleme aldığı Namuscular romanı önem arz eder. Namuscular romanı, Cumhuriyet’in ilk yıllarının siyasi, sosyal ve kültürel panoramasını ortaya koyan önemli bir eserdir. Yazar, romanında cezaevindeki mahkûmların gözünden dönemin karşıt düşüncelerini, siyasi ve sosyal atmosferini yansıtmakla kalmaz, eril söylemi de analiz etmeyi amaçlar. Bu yönüyle eser, dönemin toplumsal yapılarını besleyen dinamikleri anlamamıza imkân sağlar. Çalışmada Namuscular romanında da yer alan eril ve dişil söylemler, Bourdieu’nun bakış açısıyla tahlil edilmeye çalışılmıştır. Bu noktada onun temel paradigmalarını elbette birbirinden ayırmak mümkün değildir. Ancak çalışmanın hacmi dikkate alınarak daha ziyade eril tahakküm anlayışı doğrultusunda eril söylemlerin eylemsel ve düşünsel pratiğe yansımaları ele alınmıştır. Makaleyle Namuscular romanının dönemin toplumsal cinsiyet ve eril söylem ekseninde dönemin sosyal dokusunu yansıtan bir derinliğe sahip eser olduğunun ortaya konulması hedeflenmiştir. Bununla aynı zamanda Namuscular romanının toplumsal cinsiyetler üzerinde yapılacak akademik araştırmalara kaynaklık edebileceği değerlendirilmektedir. Çalışmada doküman tarama modeli kullanılmış, veriler betimsel içerik analiz yöntemiyle değerlendirilmiştir. Makalenin çalışma grubunu ise Kemal Tahir’in Namuscular adlı eseri oluşturmaktadır.
Bus Transfer Factor as Congestion Management Method for Local Energy Trading
Authors: Wirasanti Paramet , Tubteang Natnaree
Published: June 2024

To enable local energy trading in the distribution network, a market operator and a system operator are required. The market operator is in a character of business model and responsible for market clearing. The system operator supervises the network in order to operate according to market clearing results. In this paper, the function of the system operator is focused. Since, the market participants bid the price and the quantity of power based on their benefit, a challenge for the system operator is how to manage if there is a congestion problem. For this purpose, a bus transfer factor is developed. It is a factor that reflects the change of power in the line compared to the change of generation power in the bus. This factor can use as a sharing factor for increasing or decreasing the generation power of market participants. To validate the bus transfer factor method, the study case is provided. A comparative result between the proposed method and the load curtailment method shows that the proposed method can solve the congestion problem with the minimum adjustment.
Setting and Coordination Strategy of Over Current Relays in Medium Voltage DNs with DG Integration
Authors: Majeed Ammar A. , Abderrahim Mohamed , Alkhazraji Afaneen
Published: June 2024

Distributed Generation (DG) embedded with Distribution Networks (DNs) has been developed because its performance has become more efficient and sustainable. This reconfiguration mode increases the short-circuit current (SCC), and subsequently heightens the complexities involved in both the setting and operation of the overcurrent protection system. Therefore, it is necessary to develop a robust protection strategy for DNs integrated with DG to prevent the electrical equipment from collapsing during abnormal conditions. This study proposed one of the most important and reliable strategies for resetting and re-coordinating overcurrent relays (OCRs) that operate in the same protection zone of the distribution feeder. This methodology restricts the main variables and elements used in the protection device (PD) setting after DG is embedded to redesign a suitable setting and coordination. However, international, and national benchmark standards are used to specify suitable equations that satisfy high-protection system characteristics to ensure the reliability of DNs according to a real case study of a medium voltage level 33kV in the electrical distribution feeder of Baghdad, Iraq.
A Study on Combustion Temperature of a Rocket-Type Ceramic Burner Using CNG as Fuel by Computational Fluid Dynamics
Authors: Sangsopha Arthit , Matthujak Anirut , Sriveerakul Thanarath , Phongthanapanich Sutthisak
Published: June 2024

This study aims to investigate the combustion temperature of a rocket-type ceramic burner when using Compressed Natural Gas (CNG) as a fuel instead of Liquefied Petroleum Gas (LPG) through Computational Fluid Dynamics (CFD) methods. The simulations were conducted using Fluent 2021 R2 with a 3D model, comparing the combustion temperature of CNG with LPG. The results reveal that as the heat input increases, both the flame length and maximum temperature rise. At 30.02 kW, the maximum temperatures obtained from LPG and CNG were 1396 and 1842 K, respectively. Moreover, the maximum temperatures from CNG were consistently higher than those from LPG at all heat inputs. This difference is attributed to the higher primary air intake from CNG, enhancing the effectiveness of premix combustion. Consequently, transitioning from LPG to CNG as a fuel for a rocket-type ceramic burner holds the potential for energy savings and reduced emission.
CFD Investigation of Three-Dimensional Flow Phenomena in a MONJU 169-Pin Wire-Wrapped Fuel Assembly
Authors: Park Seongchul , Jeong Jae-Ho
Published: June 2024

A comprehensive investigation of the three-dimensional flow phenomena within the wire-wrapped 169-pin fuel assembly of the Japanese loop-type sodium-cooled fast reactor MONJU was conducted through numerical analysis using the widely-used commercial computational fluid dynamics code STAR-CCM+. The intricate vertical flow patterns within the wire-wrapped 169-pin fuel assembly were accurately represented through Reynolds-averaged Navier-Stokes flow simulations, including the turbulent stress transport model. The results of the Computational Fluid Dynamics (CFD) analysis exhibit a favorable alignment with the temperature distribution trends when compared to experimental data. Furthermore, a strong correlation between the temperature distribution of the experimental results and the CFD analysis outcomes was observed, indicating the effective reproduction of the observed temperature distribution within the experimental dataset. This underscores the capability of numerical analysis in faithfully replicating the temperature distribution as observed in the experimental data.
Renewable Integration for Green Urban Mobility: A Case Study of Public Transport Depot Electrification
Authors: Colombo Cristian Giovanni , Saldarini Alessandro , Longo Michela , Ota Ryosuke
Published: June 2024

This paper analyses an electrification strategy for a depot for a public transport company, through an optimized model. The case study analyses both the transition of a depot able to host 10 buses towards e-buses and proposes the integration of a micro-grid, powered by PV panels to power the e-buses in a sustainable way.

Published: June 2024

With the popularization and extensive use of power grid, people’s lives and many factories generally rely on electricity, and once the power grid is damaged and fails, it will seriously endanger the social order and economic benefits. At present, the research on the rescue dispatch of electric vehicles as an emergency power source mainly focuses on path planning, and does not consider the comprehensive rescue ability of the rescuers dispatched, nor does it involve the matching degree of rescuers and rescue vehicles. In this paper, the rescue urgency is obtained through the analysis and evaluation of the fault point, the characteristics of the rescue vehicles and rescue personnel are analyzed to screen out the appropriate rescue vehicles and personnel, the Euler distance is used to solve the matching coefficient between the rescue vehicle and the rescue personnel, and finally the multi-objective power grid fault emergency rescue function considering the matching of human and vehicle characteristics is established.

Authors: Ibrahim Rania A. , Gaber Ibrahim M.
Published: June 2024

Electric vehicles (EVs) are penetrating rapidly into the transport sector, profoundly impacting the electricity and energy sectors. While EVs bring many benefits, they present challenges to utility grid operators, particularly during charging their batteries. Uncoordinated charging stands out as a critical charging strategy requiring attention to mitigate potential adverse effects on power grids. Smart charging and vehicle-to-grid (V2G) technologies enable intelligent and bidirectional power transfer between the EV and the grid taking into account network conditions and requirements. However, the widespread adoption of these technologies depends on the formulation of effective infrastructure and regulatory frameworks. This paper presents the effects of unmanaged charging of EVs on the utility grid power quality such as voltage violations, utility assets overloading and harmonic distortion. The paper also sheds light on some mitigation strategies incorporated in literature to reduce the adverse effects of EV integration.

Published: June 2024

Cooling photovoltaic (PV) panels is essential for maintaining their electrical performance at optimal levels. Photovoltaic-thermal (PVT) technology, which is a hybrid system of PV cells and thermal loops, is widely used in which the PV panel can be cooled through the channel. In addition, wavy surfaces can improve heat transfer between the working fluid and the wall of the channel due to increasing turbulence intensity and improving the mixing of fluid flows. As a result, in this study, the impacts of the variation of solar heat flax and ambient temperature on the electrical efficiency and the thermal performance of a PVT applying wavy channels under certain wavelength and amplitude ratios and Reynolds number are investigated. The total efficiency of the PVT including a wavy channel has an increase of 14.8% with the increase in the surrounding temperature from 28 oC to 38 oC, while the power generation efficiency decreases from 10.5% to 10.3%. Results of numerical simulations demonstrated that both solar irradiation intensity and ambient temperature are highly impactful in the performance of the wavy channels in the cooling of the PVT cells and thus affecting their power generation and total efficiencies.

Published: June 2024

The residential sector in Brunei is the highest electricity consumer due to the cheap electricity tariff. The high consumption, primarily generated from natural gas, causes environmental harm. The government implemented a net-metering program to encourage the residents to adopt PV systems, but cheap tariffs hinder the adoption. Hence, this study aims to learn the role of electricity tariffs in adopting PV systems and consequently study the effects on the carbon footprint. This study calculated the sizes of the most cost beneficial PV systems under four electricity tariff structures: (1) current tariff, increasing block tariff (IBT), (2) previous tariff, decreasing block tariff (DBT), (3) proposed IBT tariff (mild), (4) proposed IBT tariff (aggressive). Then, economic feasibility and environmental studies were conducted. Lastly, this study investigated what the results would mean nationwide. The study found that under the current IBT and DBT, it is highly infeasible for the residents to install PV systems in terms of both economic and environmental. Under the mild IBT, the PV systems were calculated to have a payback period (PB) of 25 years and a return on investment (ROI) between -9.8% and 0.1%. On a positive note, the pollutant gas emissions can be reduced by 173,541kg/year nationwide, (14%) of the current emissions. Under the aggressive IBT scheme, the PB is between 18.02 and 22.93 years, and the ROI is between -1.8% and 1.7%. The total gas pollution in the country can be reduced by 254,212kg/year nationwide, 21% of the current emissions. Nationwide, implementing the mild IBT or the aggressive IBT can motivate the residents to install PV systems which could generate between 240 MW and 376 MW. Based on the results, although it is highly infeasible for the residents to install PV systems under all the tariff structures, there is a positive outcome in reducing carbon emissions and reaching the national renewable energy goal.

Published: June 2024

Amidst the reserves of fossil fuels and surging energy demands, the focus has shifted towards harnessing renewable energy sources like wind energy. This research endeavors to pinpoint the optimal design for a low Tip Speed Ratio (TSR) H-Darrieus turbine at three distinct TSRs: 2.33, 2.64, and 3.09. The study synergizes Computational Fluid Dynamics (CFD) with the Metamodel of Optimal Prognosis (MOP) response surface methodology. The Joukowsky transformation parametrization is applied to symmetrical airfoils, evaluating three pivotal parameters: the a/b ratio, m, and pitch angle. Notably, the pitch angle emerges as the predominant contributor, accounting for over 76% of the effect. Through Gradient-based optimization techniques, the refined turbine design achieved a performance enhancement, peaking at 14.73% for a profile optimized at a TSR of 2.64. Additionally, this work presents an insightful comparison of the non-dimensional velocity and torque coefficients across the considered TSRs. The integration of Ansys Fluent and Ansys OptiSlang in this research affirms a robust, cost-efficient, and fitting approach to dissect fluid dynamics in intricate, computation-intensive CFD models across varying TSRs.

Published: June 2024

This paper proposes an enhanced battery management system (BMS) that consists of a combined scheme of a non-dissipative direct cell-to-cell equalization algorithm and an energy support algorithm in order to protect the lifespan of a lithium-ion battery pack. The above can be accomplished by means of an auxiliary energy storage system which may consists of supercapacitors (SCs), or batteries and it is utilized to temporarily store/recover electric energy to/from any cell of the main battery pack. Specifically, the equalization algorithm regulates the amplitude of each battery balancing current by considering the State of Charge (SOC), the State of Health (SOH), the residual available capacity and the residual available energy of each battery cell as well as the energy losses of the matrix switch converter at steady state operation. Furthermore, energy support is provided in case of dynamic conditions to any weak or problematic battery cell, aiming to extend the time interval that the battery bank remains at the safe operating zone. The effectiveness and the practicality of the proposed combined equalization and energy support technique have been validated by simulation results that are extensively discussed throughout the paper.

Authors: Kinoshita Erika , Deng Mingcong
Published: June 2024

Lightening the weight of the robot arm improves work efficiency, but at the same time increases arm vibration, which has a negative impact on the improvement of work efficiency. The vibration of the arm must be controlled in order to achieve high speed and high precision movement while reducing the weight of the arm. In this study, piezoelectric elements, which are one of the smart materials, are used to control the vibration of the L-shaped arm. However, piezoelectric elements exhibit hysteresis characteristics in both actuators and sensors, necessitating compensation. In this study, control system design based on operator theory is conducted, taking into account the hysteresis characteristics of both actuators and sensors. Central Pattern Generator (CPG) is being used to control vibrations while performing hysteresis compensation. The parameters of the CPG are optimized using Ant Colony Optimization (ACO). Finally, the effectiveness of the control is demonstrated through simulations in MATLAB and experiments.

Authors: Ziba Kondwani , Xiao Song
Published: June 2024

High-speed train fast movement has a relative effect of instantaneous grounding circuit impedance change which in turn aggravates circumflux and increases train body potential. Consequently, the current entering the body can cause various effects like electromagnetic interference to onboard equipment which may affect normal operation of sensitive equipment like sensors. This paper addresses transient operation with the consideration of transient overvoltage resulting from pantograph lifting and lowering. Therefore, in ensuring safety of equipment and passengers, mobile grounding system of the high speed takes into account the indicators of current and overvoltage and their influence on the electromagnetic environment. To analyze the system, an equivalent circuit of the whole ‘train-rail’ mobile distributed grounding system is constructed based on the practically obtained impedances. This circuit facilitates the examination of current flowing through grounding wheels. Additionally, a 3D model is constructed using finite element (FEM) software to evaluate the effect of TB current on vital vehicle-mounted equipment. The study compares multi-physical distributions under different grounding schemes, emphasizing critical regions containing key devices and establishing an optimal grounding scheme.
