Proton exchange membrane (PEM) fuel cells have attracted significant attention due to their low operating temperature, high efficiency, and minimal emissions. Especially when hydrogen is used as fuel, water is the only product. Among the various components of PEM fuel cells, the membrane is crucial one because it enables the transfer of protons from the anode to the cathode, while ensuring that the fuel and oxidant remain separate and do not mix. Hightemperature operation (above the boiling point of water) is desired in PEM fuel cells as it enhances the kinetics and improves water management. However, the current most widely used membrane, Nafion, cannot operate at high temperatures above 90°C due to the membrane's dehydration, resulting in decreased proton conductivity and eventually, fuel cell efficiency. To overcome this issue, this study focuses on the development of new and potentially high-temperature composite membranes. Zirconium silicate, (ZrSiO4)/Polyvinylidene fluoride (PVDF) composite membranes were synthesized in this work with the following ratios: 0 wt.%, 1.5 wt.%, 3 wt.%, and 8 wt.% per mass of membrane solution via a solution casting method. Their proton conductivity was evaluated. The results showed that the addition of ZrSiO4 nanoparticles to the PVDF matrix significantly enhances the proton conductivity of the composite membranes. The highest conductivity value obtained was 2.15 x10-3 Scm-1 with a concentration of 8 wt.% ZrSiO4. The promising proton conductivity reported in this work would be an indication of these membranes' potential in PEM fuel cell applications. © 2023 Computers and Industrial engineering.

Forest fires have a significant impact on ecosystems and human life, especially in northern Thailand, where Chiang Mai is severely affected. Traditional methods for detecting forest fires have limitations, so there is a need for advanced simulation models. This research uses Agent-Based Modeling (ABM) to develop a forest fire simulation for Chiang Mai. The methodology involves collecting historical data, performing Multiple Regression Analysis, designing the simulation, and testing it. Data from 1998 to 2021, including temperature, relative humidity, wind speed/direction, burn area, and slope, were collected from various sources. Multiple regression analysis identified wind speed as the most significant factor affecting burn area. The forest fire simulation, designed using ZF Wang's spread model and tested with AnyLogic, showed that wind direction and speed are crucial in fire spread. The simulation accurately predicted high-risk areas, helping in proactive planning and response. This study confirms that wind is a critical factor in forest fire spread, providing a valuable tool for fire districts to improve preparedness and management. Future research should focus on refining the model with localized data and integrating real-time detection to improve its accuracy and applicability. © 2024 IEEE.

Mobile Ad-Hoc network is a distributed wireless network that is self-organized and self-maintained and it doesn’t require a fixed framework or central administration. Wireless nodes in a mobile ad hoc network are transient and have a short lifespan. They combine to form a self-configured, infrastructure-free network where routing is a significant difficulty. The wireless nodes in the network must synchronize in order to decide connectivity and routing. Ad hoc network synchronization includes activities including node organization, neighborhood detection, and routing. The predetermined framework resulted in an increase in network control overhead. If a node can link to every other node in the network, it is referred to as a dominating node, and a set of dominating nodes make up the dominating set. The main purpose of this article is to lessen routing overhead in the wireless network with the dominating set based routing (DSBR). In order to discover routes, shorten reroute establishment times, and increase packet delivery rates, this research presents an energy-efficient routing algorithm (EERA) that considerably increases the network performance. The effectiveness of this technique is demonstrated by the simulation analysis of the outcome. © 2023,International Journal of Interactive Mobile Technologies. All Rights Reserved.

A medical biology laboratory’s quality approach is a never-ending procedure designed to guarantee the standard of the services provided to clients. Setting up a quality management system that incorporates all of the laboratory’s operations is crucial to achieving this. This covers both the application of continuous improvement and the use of quality tools like process mapping, scorecards, and internal audits. The dedication of everyone working in the laboratory, from management to laboratory technicians, medical biologists, and administrative personnel, is essential to the success of the quality approach. Knowing that, it is crucial to build a good quality strategy in order to put into practice a quality management system and dedicate yourself to a continuous improvement approach to managing the laboratory. This strategy is based on the managers’ commitment and the participation of all laboratory actors in the definition of activities, with the goal of improving all the components that do not meet the quality goals. In this article, we focus on a reference standard that outlines the standards for proficiency and excellence in a medical laboratory. It summarizes the key factors that should be considered throughout a medical analysis laboratory’s certification procedure. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

The Robotic Mobile Fulfillment System (RMFS) is widely used in e-commerce warehouses and includes pods, storage locations, workstations for order picking or replenishment, and mobile robots. Decision-making in warehouse systems can be strategic, tactical, or operational. Product assignment, a tactical decision, significantly impacts picking efficiency. This research concentrates on SKU-to-pod allocation, the preliminary step before simulation, involving two phases: product grouping and product combination. Effective product grouping can enhance picking efficiency, while product combination in pod allocation aims to optimize the units picked per pod, termed pile-on, thereby reducing the reliance on Automated Mobile Vehicles (AMVs). Three scenarios were examined: Random Baseline, Class Combination, and Cluster Combination. Class Combination employs ABC classification to sort SKUs into classes using Pareto’s principle, correlating SKU percentages with order frequency percentages. In contrast, Cluster Combination considers product dimensions for pod placement. Simulations determine the optimal pile-on by evaluating the units picked per pod visit to the pick station, with a higher unit count per visit indicating reduced mobile robot transport and increased efficiency. The simulations revealed that Cluster Combination, the final scenario, achieved the best pile-on, with improvements of 30.82% and 8.19% over the first two scenarios, respectively. These results were validated using one-way ANOVA. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

The use of fintech is getting closer to everyday life. However, in this case the use of fintech is also getting closer to cyber threats. Cybercrime ranks highest in terms of threats to the use of technology. This indicates user security which can be a target for cybercriminals. To take precautions, companies must carry out a risk assessment in order to minimize cyber problems that can occur. The things that will be discussed in this study are related to what risks can occur in using fintech and what are the frameworks that can be a tool for risk assessment. Through this research, a total of 31 articles will be reviewed from selected databases that already have a reputation for the quality of their articles. The results show that cyber-related risks can be categorized based on the type of crime. Overall, the user acceptance measurement model for Fintech serves to assist developers and enterprises in understanding, predicting, and increasing user acceptance of Fintech solutions, as well as informing the development of effective product strategies and improvements. There are several models in this review that measure the impact of cyber risk for fintech. The models that can be used as a measure of technology adoption for Fintech users are the Unified Theory of Acceptance and Use of Technology (UTAUT), the Protection Motivation Theory (PMT), the theory of the Sustainable Information Society (SIS), Theory of Reasoned Action (TRA), and Theory of Planned Behavior (TPB). To overcome this is with a risk assessment that can be carried out using the COBIT framework, ITIL, ISO 27001, ISO 27002, ISO 27003, ISO 27005, ISO/IEC 155044, NIST, FMEA, and the OCTAVE Allegro Framework. © 2023 The Authors.
