Blood Flow Characteristic of the Magnetohydrodynamic Flow with Cosine-Shaped Stenosis in a Cylindrical System under the Influence of Hall Effect
Authors: Nik Mohd Naser Nik Nabilah , Abdullah Ilyani , Talib Amira Husni , Aloev Rakhmatillo
Published: January 2025

The main aim of this paper is to investigate a Newtonian model of two-dimensional blood flow coupled with mass transfer in the presence of magnetic field and Hall current effect. The flowing blood is assumed to be Newtonian fluid, and the arterial wall is having cosine-shaped stenosis in its blood vessel with stenosis. The fluid dynamics are governed by the Navier-Stokes equation with the magnetohydrodynamic (MHD) principle and Hall current effect which describe the additional magnetic effects in cylindrical coordinate system. The governing equations of motion accompanied by the appropriate initial and boundary conditions are then solved using a finite difference Marker and Cell (MAC) method. The graphical results of velocity profiles, mass concentration and flow rate are presented in this paper. The effect of MHD with Hall current effect is investigated and it shows that the velocity increases as Hall parameter increases. The influence of magnetic field affects the positive and negative ions in blood which induces a Hall current that will increase the blood flow. It is also observed that the magnitude of the maximum axial velocity decreases as the magnetic field increases because of the Lorentz force acting on the blood flow.

Authors: Hadi Faeza Mahdi
Published: January 2025

This study investigates the thermodynamic performance of various adsorbent materials used in adsorption-based atmospheric water harvesting (AWH), with a focus on their application in arid regions, such as Iraq. While significant advancements have been made in developing adsorbents capable of capturing water at low humidity levels, the lack of detailed thermodynamic analysis has hindered optimal operational conditions for these materials. The study evaluates the thermodynamic efficiencies of MOF-808, MCM-41, and COF-432, comparing their performance with other materials like MOF-801, MOF-803, and Ni2Cl2BTDD. Key findings indicate that source temperature and outlet relative humidity significantly influences system efficiency, with higher source temperatures generally improving thermal efficiency. However, lower outlet relative humidity, especially at higher temperatures, can further enhance system efficiency, emphasizing the importance of effective humidity control. Additionally, the study highlights that Iraq’s elevated ambient temperatures may exacerbate efficiency losses due to higher thermal sink temperatures, underscoring the need for adaptive design strategies. The performance of various adsorbents was found to be highly material-dependent, with certain adsorbents offering superior thermal and second-law efficiencies under specific conditions. This study offers crucial insights into optimizing adsorbent selection and system design for AWH systems, particularly in challenging climates.

The Challenges and Potential of Implementing Restorative Justice for Minor Criminal Offenses in Indonesia
Authors: Mimi  , Muhamad Adystia Sunggara
Published: January 2025

Indonesia, as a nation of law, faces challenges in integrating the restorative justice approach into the resolution of minor criminal offenses. This approach is considered more humane as it prioritizes the restoration of harm to victims and the accountability of offenders rather than mere punishment. This study aims to identify the main obstacles in the implementation of restorative justice, particularly in cases of minor criminal offenses, and to provide recommendations for improving its effectiveness. The research method employs a normative approach with an analysis of legal documents and related literature. The results of the study show that although restorative justice has been adopted in several policies, such as Attorney General Regulation Number 15 of 2020 and Police Regulations, its implementation is still hindered by regulatory factors, the capacity of law enforcement, public perception, limited resources, and local cultural dynamics. The conclusion of this study emphasizes the importance of integrated legal policy reform, continuous training for law enforcement, and public education about the benefits of this approach. By overcoming these obstacles, restorative justice has the potential to be an effective and inclusive solution in reforming Indonesia's criminal justice system.

The Ashtamudi Lake in Kerala, recognized under the Ramsar Convention, showcases rich biodiversity but faces pollution threats from human activities. Of particular concern is the potential bacterial contamination of inland fishery resources due to these anthropogenic influences. The present study, seasonally analysed the total heterotrophic bacteria (THB) and E. coli in water, sediment and Villorita cyprinoides respectively using pour plate and MPN methods. Water temperature, pH, salinity, DO and BOD of water samples were also estimated. The results showed the presence of THB in water was more in monsoon season and in sediments and the organism in premonsoon season. However, E. coli counts were more in all the media in monsoon season. The E. coli count slightly exceeded the standards set by European Union for Class A waters. In general, THB and MPN E. coli values were the highest in the oyster. Pearson’s correlation showed highly significant positive correlation between THB and E. coli in all the phases. pH and salinity showed highly significant positive correlation with BAF and highly significant negative correlation with DO and rainfall. Conversely, rainfall and BOD showed significant negative correlation with BAF. The present study indicates that the density of E. coli in shellfish at some locations exceeds the standard limit set by Indian Standards.

Metal nanoparticles have unique properties and are particularly significant in addressing antimicrobial resistance and environmental challenges. This study aimed to synthesize silver, copper, and iron nanoparticles from waste corn bract using chemical and green synthesis methods and evaluate their antibacterial properties. Corn bract extract was prepared and used as a reducing and stabilizing agent in green synthesis, while the comparison was done by conventional chemical methods. The nanoparticles were characterized using UV-visible spectroscopy, FTIR, and SEM, and their antibacterial activity was tested against Gram-positive (Bacillus sp., Staphylococcus sp.) and Gram-negative (Escherichia coli, Klebsiella sp., Pseudomonas sp.) bacteria through the well diffusion method. The green-synthesized silver nanoparticles exhibited the highest antibacterial efficacy, especially against Pseudomonas sp. and E. coli, followed by copper and iron nanoparticles. Phytochemicals in corn bract extract enhanced the stability and bioactivity of green-synthesized nanoparticles, as confirmed by FTIR analysis. The results of this investigation underscore the capabilities of agricultural waste in facilitating sustainable nanoparticle production, wherein green synthesis provides enhanced antibacterial attributes in comparison to traditional chemical approaches. This research emphasizes the significance of nanoparticles synthesized through green methods in addressing antimicrobial resistance and highlights their role as a scalable and environmentally sustainable option for generating effective antimicrobial agents.

Authors: Venkatesh R.
Published: January 2025

The advantages of magnesium alloy composites over traditional engineering
materials include their high strength and lightweight for automotive
applications. The proposed work is to compose the AZ61 alloy composite
configured with 0–12% silicon nitride (Si3N4) via
semisolid-state stir processing assisted with a (sulfur hexafluoride—SF6) inert
environment. The prepared AZ61 alloy and AZ61/4% Si3N4,
AZ61/8% Si3N4, and AZ61/12% Si3N4
are machined by electrical discharge machining (EDM) under varied source
parameters such as pulse On/Off (Ton/Toff
 ) time (100–115/30–45 μs), and composition of composite. The impact
of EDM source parameters on metal removal rate (MRR) and surface roughness (Ra)
is measured. For finding the optimum source for higher MRR and good surface
quality of EDM surface, the ANOVA optimization tool with L16 design is executed
and analyzed via a general linear model approach. With the influence of ANOVA,
the Ton/Toff and composite composition found 95.42%/1.27%
and 0.36% impact for MRR and 30.74%/21.01%/18.27% of Ton,
Toff, and Ra. The optimum parameters for electrical discharge
machining have been determined, and the composite material of AZ61/8%
Si3N4 has been identified as having a favorable MRR/Ra
value compared to other materials.
Data-Driven Performance Evaluation of Machine Learning for Velocity
Estimation Based on Scan Artifacts from LiDAR Sensors
Authors: Haas Lukas , Haider Arsalan , Kastner Ludwig , Kuba Matthias , Zeh Thomas , Jakobi Martin , Koch Alexander Walter
Published: January 2025

Light detection and ranging (LiDAR) sensors are increasingly applied to automated
driving vehicles. Microelectromechanical systems are an established technology
for making LiDAR sensors cost-effective and mechanically robust for automotive
applications. These sensors scan their environment using a pulsed laser to
record a point cloud. The scanning process leads in the point cloud to a
distortion of objects with a relative velocity to the sensor. The consecutive
generation and processing of points offers the opportunity to enrich the
measured object data from the LiDAR sensors with velocity information by
extracting information with the help of machine learning, without the need for
object tracking. Turning it into a so-called 4D-LiDAR. This allows object
detection, object tracking, and sensor data fusion based on LiDAR sensor data to
be optimized. Moreover, this affects all overlying levels of autonomous driving
functions or advanced driver assistance systems. However, since such
sensor-specific effects are rarely available in public datasets and the
velocities of target objects are not included as ground truth in these datasets,
it makes sense to enrich the limited real-world data with synthetic data.
Therefore, this article discusses how such datasets can be created and combined
to efficiently estimate velocities on real-world data using the novel method
named VeloPoints.
Height Control Method for Air Suspension Systems Based on Model-Free
Adaptive Control and Improved Genetic Algorithm
Authors: Yao Jiyang , Wu Guangqiang , Wu Jian , Yang Yuchen , Yan Xudong
Published: January 2025

This article presents a height control method for air suspension systems, which
are influenced by strong nonlinearity and multiple coupling factors, based on
model-free adaptive control (MFAC) using full-form dynamic linearization (FFDL).
To address the impact of different damping coefficients of the shock absorber on
the height control effect, an improved genetic algorithm is employed to globally
optimize the relevant parameters involved in the design of the control law,
thereby enhancing the height control performance. The precision of modeling the
air suspension system has a direct impact on the simulation of both static and
dynamic vehicle models, as well as the accuracy of height control. In this
article, an equivalent thermodynamic model of the air suspension system is
established based on the principle of energy conservation for height control
research. Considering the nonlinearity of the air suspension system and the need
to make additional assumptions before modeling, a MFAC method using FFDL is
adopted for controller design. Traditional height control methods do not
consider the impact of changes in the shock absorber damping coefficient on the
height control effect. For different damping coefficients, the body height
tracking error is large when using the same height control law initialization
parameters. Therefore, an improved genetic algorithm is employed to globally
optimize the MFAC parameters under different damping states. The effectiveness
of the thermodynamic model of the air suspension system and the MFAC method for
height control, with parameters tuned using the improved genetic algorithm, was
validated through MATLAB/Simulink simulations.

Peak Adhesion Coefficient Based on Improved Brush Tire Model
Authors: Zhao Wenrui , Leng Bo , Han Yinfeng , Yu Zhuoping , Xiong Lu
Published: January 2025

The sideslip angle and tire-road peak adhesion coefficient (TRPAC) are crucial
parameters for intelligent active safety systems in automobiles. The accuracy
and real-time estimation of these parameters significantly affect control
effectiveness. And there is a strong coupling between the two parameters, which
brings great challenges to the joint estimation. This paper proposes a nonlinear
dynamic estimator that pre-estimates tire lateral force to achieve synchronous
estimation of sideslip angle and TRPAC. Additionally, to cope with sudden
changes in road adhesion condition, a TRPAC preliminary estimation optimization
algorithm is introduced. Moreover, an adaptive gain adjustment algorithm for the
sideslip angle estimator is implemented to address large lateral excitation
conditions. Simulation results on various road surfaces and under various
lateral excitation conditions demonstrate that the proposed joint estimator
enables accurate and rapid estimation of sideslip angle and TRPAC.

Electric vehicles (EVs) have developed rapidly and are popular due to their zero
emissions and efficiency. However, several factors limit electric car
development, including battery performance, cost, lifetime, and safety. Battery
management is crucial for achieving maximum performance under various
conditions. The battery thermal management system (BTMS) plays an important role
in controlling the battery’s thermal behavior. A BTMS manages the battery’s
operating temperature by either dissipating heat when it is too hot or providing
heat when it is too cold. Various methods of cooling batteries include air
cooling systems, liquid cooling systems, refrigerant cooling systems, and phase
change material cooling systems. This study focuses on an innovative BTMS
utilizing a Peltier module, regulated via the Internet of Things (IoT) platform
for real-time temperature monitoring and control. The objective of this research
is to design and develop a temperature-controlled cooling system for EV
batteries, with the ability to dynamically adjust cooling intensity and send
alerts for anomalies. The system comprises temperature sensors, a (NodeMCU)
microcontroller, and the Peltier module, all interconnected wirelessly to the
IoT platform, enabling remote management through a mobile application. The
experimental setup successfully maintains the battery temperature within a range
of 35°C–45°C, optimizing performance and preventing overheating. Real-time data
monitoring and cooling adjustments, based on temperature readings, led to a
significant improvement in thermal management, enhancing the battery’s
efficiency and longevity.

Social media's role has grown significantly, emerging as a powerful tool for companies to execute marketing strategies. While numerous studies have delved into social media, few have delved into the impact of Social Media Marketing Activities. This research examines the effects of such activities on Social Identification, Perceived Value, and Satisfaction. To empirically assess these effects, an online survey was conducted among 350 social media users for data analysis. The findings reveal that Social Media Marketing Activities indirectly influence Satisfaction through Social Identification and Perceived Value. Additionally, Social Identification and Perceived Value have a direct impact on Satisfaction, subsequently affecting Continuance Intention, Participate Intention, Purchase Intention, and Revisit Intention. This study offers managerial insights for companies in the marketing realm, emphasizing the importance of crafting and implementing innovative marketing strategies on social media that align with consumer preferences. This, in turn, fosters Social Identification and cultivates positive consumer perceived value, ultimately leading to enhanced Satisfaction.

This study examines the effectiveness of rehabilitation versus punishment in Pakistan's criminal justice system, focusing on overcrowded prisons, limited rehabilitation programs, and social stigma among former offenders. A qualitative approach was employed, employing case studies, literature reviews, and legal documents to explore existing rehabilitation programs, punitive measures, and restorative justice measures. Analysis of data revealed systemic issues, such as inadequate funding, untrained personnel, and weak post-release support that limit the effectiveness of rehabilitation. Results show that punitive measures are not enough to deter crime since socio-economic factors such as poverty and unemployment remain significant drivers. Rehabilitation programs, though promising, must be extended, funded better, and coupled with restorative justice measures. The study recommends policy changes to balance punishment and rehabilitation, public awareness campaigns, and post-release reintegration assistance to reduce recidivism. These changes can make Pakistan's criminal justice system more sustainable and fair.

Studi ini bertujuan untuk memeriksa penerapan RCCP dan TOC dalam perencanaan kapasitas produksi di Bengkel Cor Logam Sentosa Jaya. Latar belakang penelitian ini berasal dari tantangan dalam mengelola kapasitas produksi. Pendekatan penelitian kualitatif digunakan, dengan memanfaatkan metode pengumpulan data seperti observasi dan wawancara. Analisis RCCP mengungkapkan kelebihan kapasitas sebesar - 2% pada stasiun pengecoran, yang mengindikasikan kapasitas yang tidak mencukupi untuk memenuhi target produksi. Sementara itu, analisis TOC mengidentifikasi stasiun pengikiran dan pemolesan sebagai kendala utama dalam sistem produksi karena memiliki kapasitas maksimum terendah. Penerapan gabungan metode RCCP dan TOC terbukti efektif dalam menganalisis kendala di Bengkel Cor Logam Sentosa Jaya. Untuk mengatasi kendala tersebut, solusi yang paling efisien adalah menambahkan satu jam lembur bagi pekerja di kedua stasiun baik pengikiran dan pemolesan, sehingga meminimalkan penumpukan di stasiun pengecoran. Setelah kami melalukan pangambilan data dengan pemilik bengkel dan pengolahan data dengan menggunakan metode RCCP dan juga TOC solusi yang paling efektif adalah menambah 1 jam lembur setiap hari, sehingga total jam kerja menjadi 8-9 jam per hari. Penyesuaian ini akan meningkatkan kapasitas workstation pengikiran dan pemolesan dari 3715,2unit menjadi 5056,8unit dan pemolesan dari 3302,4unit menjadi 4179,6 unit.

Based on biological and ethnobiological data from 2020 to 2022, this study provides a base line for the biocultural conservation of stingless bees. These bees in Mexico, like many other pollinators, are facing population declines and this biological loss impacts traditional human knowledge and its uses. This paper aims to record the traditional ecological knowledge about these bees to establish sustainable meliponiculture. Cultural values were obtained through participant observation, interviews, free listing, and structured questionnaires, and a bee inventory was conducted. Data were analyzed using Smith’s Prominence Index and descriptive statistics using SPSS v. 25 software. Inhabitants recognized 21 floral visitors, including invertebrates, mammals and birds. ‘Tenchales’ (local term for Scaptotrigona mexicana), hummingbirds and butterflies are the most culturally prominent floral visitors. The meliponini belonging to Scaptotrigona mexicana were recognized as ‘tenchal’, although different common names were obtained for other meliponini, denoting morphological and behavioral differences among the following species: Partamona bilineata, Plebeia pulchra, Scaptotrigona pectoralis, Scaura argyrea, Trigona corvina, Trigona fulviventris, Trigona fuscipennis and Trigona nigerrima. Although the research area is located near a large city, there is substantial diversity of melliferous flora, floral visitors, and traditional ecological knowledge used by the inhabitants in their daily activities. Stingless bees are perceived as the primary pollinators that help maintain their forests and thus help sustain their lives. This paper promotes better awareness of bioculturally effective community conservation strategies.
