One of the main interests of researchers is the local scour downstream hydraulic structures due to free hydraulic jump, which can cause massive damage or collapse for hydraulic structures. In this study, a new countermeasure was developed to reduce the maximum scour dept. by using two buried plates and a sill downstream of the sluice gate. The results showed that the two buried plates were a very effective tool in reducing the maximum scour dept. downstream of the fixed apron. It was found that when the two plates were buried at (LP1/LB = 0.07 with LP2/LB = 0.14) with a sill installed at (LS/LB = 0.1 with hS/LS = 0.14), the maximum scour dept. upstream and downstream of the first plate (Ds1 and Ds2) was reduced by 57% and 64%, respectively, and the maximum scour dept. downstream of the second plate (Ds3) was reduced by 35% compared to the maximum scour dept. for the no-plate condition. An empirical formula was developed to determine the maximum scour dept.. The study results may be applied in the area of protection design for the fixed apron. © 2024 Indian Society for Hydraulics.

As urbanization accelerates, the demand for electricity rises, leading to an increased reliance on coal-fired power generation, which contributes significantly to environmental pollution and global climate change. Renewable energy, particularly wind power, presents a cleaner alternative but is limited by inconsistent availability. The storage system helps to minimize the imbalance of power generation by wind power plants due to inconsistency. Integrating wind power plants with pumped-hydroelectric storage systems (PSS) offers a solution, providing reliable and dispatchable power. This study explores a Wind-PSS hybridized integrated system's economic feasibility and environmental benefits using the standard IEEE 30 bus system network. Employing the Multi-Objective Dragonfly Algorithm (MODA), the research aims to optimize the cost and emission reductions depending on previous work. The findings indicate that the proposed system can substantially improve financial performance and environmental impact, demonstrating the potential of Wind-PSS hybridization for sustainable power generation. © 2024 IEEE.

Current human collapse detection methods are plagued by several issues. These methods often rely on manual monitoring or simplistic threshold-based sensor systems, which can be slow to respond and prone to human errors. Traditional systems frequently struggle with high false alarm rates, where non-critical events are mistaken for collapses. Conversely, they might miss actual collapses due to their limited detection capabilities. The proposed method aims to detect falls in video footage by using pose estimation techniques. The project utilizes the OpenPifPaf library to extract keypoints of a person and Shufflenetv2k30, which is a pre-trained model that can be used to extract relevant features from input images, essential for accurate human pose estimation. It focuses on calculating the velocity change at the neck keypoints to identify falls. The velocity threshold is fine-tuned for the current dataset. When a fall is detected, the system continuously monitors the person to determine whether they remain motionless. If the person remains still for a predefined period, an alarm is triggered. The alarm service can be customized, allowing the system to connect with different types of alert mechanisms. Here, a mobile computing system and application are utilized for the same. The method is evaluated with the Le2i public dataset. © 2025 IEEE.

The increasing integration of inverter-based re-sources (IBRs) in modern power systems poses challenges to traditional grid conventions due to features such as low inertia and limited fault current supply. Since IBRs exhibit distinct fault characteristics compared to synchronous generators, a reevalu-ation of existing protection schemes is necessary. Understanding the transient response of IBR during faults is crucial for both protection system design and ensuring that its outputs remain within the maximum limits of internal semiconductor materials, which is a factor heavily influenced by manufacturer-specific con-trol settings. While electromagnetic transient programs (EMTP) provide valuable insights, their application to large power systems is computationally intensive, underscoring the need for analytical fault models. This paper addresses these challenges by converting EMTP models of grid-following IBRs into transfer function models to study transient response. Additionally, it attempts to derive fault current expressions for LC-filter-based inverters and identifies the corresponding factors that influence the resulting transients. The accuracy of the developed analytical model is also evaluated against simulations in PSCAD. © 2024 IEEE.

engineering has evolved from perceptions of the ways natural and constructed systems respond and from the improvement of empirical formulas that give bases to design. Centuries before it was known that engineering consists of just two fields, military and civil, civil engineering remains an umbrella term including numerous related specialties. As a result of increasing the cost of non-renewable energy resources, the world trends to find other renewable and sustainable resources for supplying power to electronic devices, generators, and much more applications. It's also worth mentioning that generating electricity in traditional ways is considered a complex method. Energy harvesting is defined as scavenging energy from the environment or natural resources such as wind, rain, waves, human activities, and earthquakes for (Structural Health Monitoring) SHM purposes, Piezoelectric mechanism is chosen in this paper for energy harvesting because of its advantages compared to other mechanisms such as its smaller size, fewer moving parts, simpler design, and its higher efficiency. This paper includes the energy efficiency investigation for different energy sources of vibration such as wind, rainfall, and earthquake using MATLAB Simulink environment. The wind is considered the most efficient source due to the high power values that can be obtained, and its continuity under all circumstances. © 2024 IEEE.

This literature commences with an overview of electric vehicles, encompassing their diverse types, charging topologies, and future prospects. Subsequently, the paper delves into the dynamics of vehicle motion, elucidating the forces at play during acceleration, with simulations conducted using MATLAB/Simulink. Visual representations of electric vehicle systems are provided, serving as a precursor to forthcoming Simulink realizations. Furthermore, the paper outlines the dynamic mathematical modelling of electric vehicles in subsequent sections. The discussion transitions to the simulation and mathematical analysis of various converters utilized in electric vehicles, including rectifiers, inverters, and choppers. Battery-related calculations are then explored, addressing the requisite number of cells in series and parallel configurations for optimal vehicle operation. Finally, the project scrutinizes three potential issues - cell equalization, voltage limits violation, and thermal anomalies in the battery - during vehicle operation or charging. A simulation model is presented as a proposed solution to mitigate these challenges, underscoring the comprehensive approach of this research endeavor. © 2024 IEEE.
