Home design features post-COVID-19Journal of Engineering and Applied Science - Tập 69 - Trang 1-20 - 2022
Nancy H. Alhadedy, Hisham S. Gabr
The long stay at home during the COVID-19 pandemic implied that most people had to perform all their daily activities at home. That raised the need for special home features related to the health, safety, and well-being of residents. This study aimed to explore the most essential features of home design during the pandemic and to measure the perception of their importance by Cairenes (Egypt) and c...... hiện toàn bộ
Investigation and optimization of factors affecting the accuracy of strain measurement via digital image processingJournal of Engineering and Applied Science - - 2024
Ivan Miskdjian, Hossam Hodhod, Mostafa A. M. Abdeen, Mohamed Elshabrawy
AbstractDigital image processing is used to create an optical extensometer to measure deformation in materials under quasi-static loading. The optical extensometer setup created in the present work is a single camera setup which is a two-dimensional system. The main objective of this work is to create an optical extensometer system by digital image processing to me...... hiện toàn bộ
Flexural performance of T-shape light-weight concrete filled steel tubular girderJournal of Engineering and Applied Science - Tập 70 - Trang 1-30 - 2023
Mohamed Emam El-Kherbawy, Alaa M. Morsy, Maheeb Abdel-Ghaffar, Yasser A. Khalifa
This paper proposes an optimization study for both structure and materials to obtain an affordable, long-span, light-weight, and fast-constructing T-shape lightweight concrete-filled steel tubular (LWCFST) girder in order to be used in bridge construction. This research was performed on a hollow steel tube of Steel-52 (yield limit 360 MPa), which was filled with LWC. A set of parameters had been i...... hiện toàn bộ
Terrain-based adaption of propagation model loss parameters using non-linear square regressionJournal of Engineering and Applied Science - Tập 68 - Trang 1-19 - 2021
Joseph Isabona, Agbotiname Lucky Imoize
Reliable and real-time propagation loss modeling play a significant role in the efficient planning, development, and optimization of macrocellular communication networks in a given terrain. Thus, the need to adapt or tune an existing model to enhance its signal prediction accuracy in a specified terrain becomes imperative. In this paper, we proposed and applied a non-linear square regression metho...... hiện toàn bộ
Parameter optimization of rubber cylinder of expansion liner hanger based on numerical simulationJournal of Engineering and Applied Science - Tập 69 - Trang 1-18 - 2022
Yong Chen, Xin Liu, Hao Yi, Chuan He, Guoping Xiao, Jinjin Tan, Haochen Wu, Anqiao Su
The expansion liner hanger has great advantages over the traditional slip liner hanger. Therefore, scholars at home and abroad have carried out extensive research on the expansion liner hanger, but there are few researches on the optimization design of the rubber cylinder of the expansion liner hanger. How to select the size and material of the rubber cylinder is very important to the suspension p...... hiện toàn bộ
