Despite their many advantages, a WE system based on a doubly fed induction generator is vulnerable to power grid disruptions. Due to being built on traditional controllers, the generator systems with standard vector control (VC) cannot resist disturbances. This paper seeks to provide a novel VC that is resistant to outer perturbations. For this purpose, a finite state space model predictive control (FS-MPC) is utilized instead of the internal current loop of the standard VC. The objective of the proposed system is to minimize the error between the measured currents and their reference values and, also, reduces the total harmonic distortion (THD) of the current. The cost function can optimize this requirement, which reduces the computation time. The VC-FS-MPC was implemented using the MATLAB, where a 1.5-MW generator operating under different conditions was used. The necessary graphical and numerical results were extracted to show the efficiency, effectiveness, and ability of the VC-FS-MPC to improve the characteristics of the studied energy system. The results show the flexibility and distinctive performance of the VC-FS-MPC in the various tests used, as the THD of stator current was reduced in the second test compared to the first test by an estimated percentage of 61.79%. Moreover, the THD of rotor current was reduced compared to the first test by an estimated percentage of 23.56%. These ratios confirm the effectiveness of the VC-FS-MPC in improving the characteristics of the proposed system.","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"74 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141867868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These components include the impeller, diffuser, and volute. However, there is a limited number of published papers studying the combined performance of individually optimized components working together. This article presents a hierarchy optimization approach conducted on a turbocharger compressor, composed of two or three individually optimized components including two optimized impellers, one vaned diffuser and one optimized volute, each with distinctive optimization method. The article also reports the resulting improvements in pressure ratio and overall isentropic efficiency of the machine, by means of investigations of nine different compressor configurations, including the original design. Experimental tests are performed at several rotational speeds and different mass flow rates to generate compressor performance maps. To simulate the compressor flow field, a three-dimensional steady-state compressible turbulent flow simulation code is employed and evaluated with experimental data. The results show that a configuration using an optimized impeller, vaned diffuser, and an optimized volute, improves efficiency and pressure ratio up to 11.3% and 16.5%, respectively, which are significant enhancements and important achievements. A detailed examination of the flow field reveals that in this particular configuration, pressure fluctuations at the impeller exit decrease by 71%, and the average pressure at the impeller exit increases up to 46% compared to the original design. Furthermore, flows in the impeller passages become more uniform, with limited separation regions near the trailing edge of blades.","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"46 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141868037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The outcomes demonstrated the feasibility of oblique stilling basin. However, the oblique angle of stilling basin has an impact on the flow, and the smaller the angle, the greater the impact. The specific manifestations are: Firstly, the hydraulic jump is oblique, and when the upstream energy exceeds a certain value, a hydraulic jump occurs on the obtuse angle side formed by the starting section, while no hydraulic jump occurs on the other side. And there is a large difference in the water level between the longitudinal and cross sections in the stilling basin, and the smaller the angle, the greater the difference caused. Secondly, the water level on the obtuse angle side is higher than that on the acute angle side, and the smaller the angle, the greater the change, with the lowest water level occurring on the acute angle side; the oblique angle of the stilling basin causes uneven energy at the starting section, with greater energy on the acute angle side than that on obtuse angle side, and smaller angles have greater energy.

A cost-effective technique to mitigate build-up heat and improve the thermal cycle is accomplished with the introduction of an inter-layer dwell time (ILDT). The study investigates the impact of ILDTs of 60, 90, 120, 150, and 180 s on the properties of the printed parts. The grain refinements were achieved at higher ILDT with no appreciable changes in the compositions. However, a slight increase in oxides and (delta )-ferrite was detected. The study found improved part density, mechanical and tribological performance while reduced corrosion-resistant properties with increased ILDT. Furthermore, to understand the effect of ILDTs on location-based thermal cycling and distribution, numerical models of the process were established. The peak temperature gradually reduces with an increase in ILDT. Heat accumulations within the three-layered WAAM-built structure lessen by 70% approximately with increases in ILDT from the 60 s to 180 s. The results observed repeated thermal cycles of the previously deposited layers and reduction of peak temperatures with subsequent layer deposition irrespective of the ILDTs. The trough temperature slightly reduced with ILDT; however, at higher delay periods the variations were found to be more stable. The study discovered too low and too high ILDT is detrimental and therefore an appropriate mid-range ILDT of 120 s is suggested to fabricate medium-size WAAM-built components based on experimental and numerical investigation considering overall production time and functional properties.","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"171 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141868035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Parametric variation of the controlling parameters, such as Reynolds, Grashof, and Richardson numbers, is carried out along with the alteration of the size of the solid object.

Qualitative visualization of isotherms and streamlines is also provided. The current findings reveal the dominant influence of object size on thermal efficiency and flow patterns.

MMCs possess excellent properties including being light in weight, high corrosion resistance, stiffness, and strength.

To improve the machining process quality and to avoid unnecessary experiments in a cost-effective manner, this article aims to develop an artificial intelligence model, using the genetic programming (GP) method to predict the cutting force, surface roughness, and tool life during the machining process of SiCp/Al at different cutting parameters including cutting speed, feed rate, and depth of cut.

Meanwhile, the GP parameters including mean square error, root means square error, normalized mean square error, mean error, variation of error, correlation coefficient, and R-square are used for the validating of the proposed model. The GP model results are compared with our previous response surface methodology (RSM) model results that were employed to estimate the machining characteristics of the SiC particle-reinforced metal matrix composites (45% SiCp) with different cutting parameters.

Despite substantial interest, there remains insufficient research investigating the impact of adversarial attacks in real-world scenarios. Moreover, adversarial attacks have been extensively examined within the digital domain, but adapting them to realistic scenarios brings new challenges and opportunities. Existing physical world adversarial attacks often look perceptible and attention-grabbing, failing to imitate real-world scenarios credibly when tested on object detectors. This research attempts to craft a physical world adversarial attack that deceives object recognition systems and human observers to address the mentioned issues. The devised attacking approach tried to simulate the realistic appearance of stains left by rain particles on traffic signs, making the adversarial examples blend seamlessly into their environment. This work proposed a region reflection algorithm to localize the optimal perturbation points that reflected the trusted regions by employing the trust region optimization with a multi-quadratic function. The experimental evaluation reveals that the proposed work achieved an average attack success rate (ASR) of 94.18%. Experimentation underscores its applicability in a dynamic range of real-world settings through experiments involving distance and angle variations in physical world settings. However, the performance evaluation across various detection models reveals its generalizable and transferable nature.

This model aims to investigate the interaction behavior between enterprises, contact center departments, and customers, identifying the specific conditions and influencing factors for improving call center resilience. The study reveals that: 1) The balance of strategies among all three parties is influenced by enterprise support, subsidies, penalties, and stakeholder behaviors. 2) The punishment level enforced by the enterprise and the initial willingness of the enterprise and customer significantly affect the behavior of the contact center department. 3) Subsidies from enterprises can impact customers decisions.
