This is done by pouring it into molds, then drying and finally foaming it. One of the most important problems accompanying the drying of bicarbonate foam is the phenomenon of shrinkage in the models resulting from the liquid leaving it by evaporation, resulting in capillary pressures generated inside it. Due to the shrinkage phenomenon, defects and cracks sometimes occur during the drying process that appear on the surface. The process of defects and cracks formation during the drying process depends on the drying conditions such as temperature, relative humidity, and the type of used support angle θ (in addition to the mechanical specifications of the models). Understanding the drying procedures helps researchers and workers in the production of such porous materials, and in choosing the appropriate drying conditions and avoiding any defects in the product. In this study, the effect of the mechanical specifications of the model was investigated by adding surface tension-reducing agents at different concentrations to the models during the drying process, as well as studying the effect of the contact angle (θ) of the support on the probability of crack formation and the mechanical specifications of the dried model. It was found that the value of the contact angle (θ) has a direct effect on cracks and defects. Increasing the value of the contact angle from θ = 30° to θ = 150° leads to a reduction or treatment of the cracks that appear in the models. It was also found that adding surface tension-reducing agents such as SLES and SDS leads to crack formation in the models, and increasing the concentration of surface tension-reducing agents such as SLES and SDS leads to foam collapse. However, adding surface tension-reducing agents such as C8AC and C10AC did not show any cracks for all concentrations. As for the mechanical properties of the dry models, they are directly affected by the type of surfactant (C10AC and C8AC), which led to the formation of models with porosities higher than 90%. As for the concentration of the surfactant, it has an effect on the wet model, while it does not affect 90%.

The MLFFNN employs the temperature and radiation as the inputs and the power as the output. For training and testing the MLFFNN, data of 6 days are acquired from a real PV power station in Egypt. The first five days are employed to train the MLFFNN using Levenberg-Marquardt (LM) algorithm.

It can be applied in the solid and fusion states. In the fusion state welding, the amount of the heat generated highly affects the quality of weldments from the mechanical properties point of view. To study this effect, three different fusion welding techniques were used to weld low carbon steel samples: Shield Metal Arc Welding (SMAW), Metal Inert Gas Welding (MIG), and Oxy Acetylene Welding (OAW). The mechanical properties of the welded joints were evaluated using mechanical tests such as tensile strength, hardness , and impact toughness. The results showed that MIG weldments have the best mechanical properties among the other welding techniques ,the reason is due to the amount of heat in the welding region in the (MIG) method is much less compared with other welding methods, which makes the size of the heat-affected zone (HAZ) less and thus obtaining smaller grains size in this area, which leads to an improvement mechanical characteristics of the welds.","PeriodicalId":259142,"journal":{"name":"SVU-International Journal of Engineering Sciences and Applications","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126521818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The case study of a gear (with 75 teeth) and pinion (with 25 teeth) from Alloy steel are analyzed using theoretical Von-Mises’s equation using finite element method under static conditions using software package SOLIDWORKS. The contact stress between the gear tooth pair's engagement impacts the gear's ability to transmit power.

Intelligent transportation systems try to overcome these problems by finding smart ways to detect traffic congestion. One of the essential issues in these systems is selecting the appropriate features to detect traffic congestion. Most of the current methods utilize motion or texture features only, which have their limitations. In this paper, a deep neural network (DNN), which has two input paths, is proposed for traffic congestion recognition. It handles the evolution of motion as well as texture through its two inputs simultaneously via Long Short-Term Memory (LSTM) layers. Gaussian noise layers are used to increase the generalization ability of the DNN and to enable training on small datasets without over-fitting. Experimental results applied to the UCSD and NU videos datasets assert the robustness of the proposed method. It achieves an accuracy of 98 % which is high in comparison to the state-of-the-art methods.","PeriodicalId":259142,"journal":{"name":"SVU-International Journal of Engineering Sciences and Applications","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120955904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
