Title: ON SOME MATRIX INEQUALITIES Authors: Abu-AS'AD, Ata Abstract: In this paper, we show the convergence of matrix series and the conditions for their convergence by finding an upper bound for some specific matrix inequalities. Finally, we introduce a new form of arithmetic-geometric matrix series and analyze their convergence.

Title: Electric Vehicle Technologies in the Smart Grid Era: A Comprehensive Review Authors: Refaat, Shady S.; Mohammed, Amira; Foqha, Tareq; Syed, Ahmed; Alsadi, Samer; Farrag, Mostafa Abstract: Electric vehicles (EVs) present an efficient solution for reducing greenhouse gas (GHG) emissions and enhancing grid power quality. They offer multiple advantages over traditional internal combustion engines (ICEs), including lower emissions, reduced dependence on oil, higher energy efficiency, quieter operation, zero emissions, and improved air quality by minimizing the release of toxic chemicals into the atmosphere. However, there is a lack of literature that comprehensively reviews the factors that can facilitate the assimilation of EV technology. Therefore, this paper provides a comprehensive review of EV technologies, focusing on the growth of global EV adoption and the various types of EVs, including all-EVs and hybrid EVs (HEVs). The comparative analysis of different HEV technologies is presented, covering full HEVs, mild HEVs, and plug-in HEVs (PHEVs). The paper also discusses the different classifications of HEVs based on electrification level and energy source, along with a comparative analysis of their configurations. Furthermore, the EV architecture is examined, with a specific focus on electric motors, battery management systems (BMSs), batteries, and charging technologies, including conductive and wireless charging systems. The challenges in EV charging and the associated charging standards are also addressed. The paper concludes by highlighting the need for the advancement of EV technologies and infrastructure to overcome the significant barriers to rapid EV adoption, while demonstrating how smart grid technologies enhance EV charging efficiency, grid resilience, and energy sustainability.

Title: Implementing a Load Shedding Using the Golden Eagle Optimization through the Internet of Things-Based Smart Power Sockets Authors: Jallad, Jafar Abstract: In the event of a power system tripping or overloading, a load-shedding scheme is activated to shed a portion of the load buses and restore the frequency to a stable level. However, this method makes many houses blackout for a long time. This paper presents an approach for implementing a load-shedding scheme at the household level to distribute the total load curtailments among all consumers. The integration between the IoT-based smart sockets and Golden Eagle Optimization (GEO) shows an efficient load-shedding method for preventing a full blackout at the consumer level. The results show an efficient control of load appliance at end user by control room in utility grid to implement a load shedding scheme with optimum total load curtailment.

Title: Exploring the Practices and Strategies of Active Learning in Higher Education Authors: Razia, Bahaa Subhi; Awwad, Bahaa Subhi Abstract: Active learning has gained increasing educational, and research interest. Active learning has a broad definition. This paper provides a comprehensive guide for instructors who aim to engage their students in the learning process. It examines the transition from passive to engaging approaches in higher education by examining active learning practices. It uses a mixed-methods approach in universities in the Arab area to collect data through surveys and interviews. The growth of communication skills, planning obstacles, and student engagement are highlighted in the qualitative findings. Active learning's effectiveness is dependent on increasing engagement, as demonstrated by a positive correlation between critical thinking and quantitative analysis conducted with SPSS. Time management and skill regulation are two difficulties. Successful implementation requires careful planning, alternative assessment, and continuous skill development. The study focuses on the significance of institutional support to assist teachers in reaping the benefits of active learning.
