It serves as an essential component of various advanced problems in the field, such as motion analysis, event detection, and activity understanding. VOT finds extensive applications, including human-computer interaction in video, video surveillance, and autonomous driving. Due to the rapid development of deep neural networks（DNNs）, VOT has achieved unprecedented progress. However, the lack of interpretability in DNNs has introduced certain security risks, notably backdoor attacks. A neural network backdoor attack involves an attacker injecting hidden backdoors into the network, making the compromised model behave normally with regular inputs but produce predetermined outputs when specific conditions set by the attacker are met. Existing triggers for VOT backdoor attacks are poorly concealed. We leverage the sensitivity of DNNs to small perturbations to generate pixel-level indistinguishable perturbations in the frequency domain, thus proposing an invisible backdoor attack. This method ensures both effectiveness and concealment. Additionally, we employ a differential evolution（DE） algorithm to optimize trigger generation, thereby reducing the attacker's required capabilities. We have validated the effectiveness of the attack across various datasets and models.","PeriodicalId":44451,"journal":{"name":"Journal of Electrical Systems","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141661318","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 generator in the conventional wind energy conversion system uses kinetic energy from the wind to produce electrical energy. Owing to wind fluctuations, the generator's output is connected to the load via a rectifier and inverter to keep the voltage at the load side constant. The 2-stage conversion phenomenon has its limitation of being expensive along with possessing lower efficiency. Z source inverters offer a novel conversion approach and can utilized to alleviate the limitations. However, they come with certain downsides as well, such as unequal input current, high inrush current, and high voltage stress. The quasi-Z source inverter (QZSI), a single-stage power converter based on the Z source inverter topology, can overcome it. It performs this by using an impedance network that couples with the source and the inverter to provide a voltage boost for the wind power generating system. In this paper, a comparative study of different control strategies of quasi-z source inverter is performed for a wind power system to find out one efficient strategy. ","PeriodicalId":44451,"journal":{"name":"Journal of Electrical Systems","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141835396","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}

This can be attributed to its capacity to represent the intricate physical and chemical dynamics of the degradation mechanism. The study also summarizes other studies that suggested “machine learning” may be used to support the assessment of reinforced concrete building durability. Comprehensive discussion is also held regarding the benefits of using machine learning to evaluate the service life and durability of “reinforced concrete” buildings. It is becoming easier to apply “machine learning for durability and service-life” evaluation thanks to the growing trend of wireless sensors gathering an increasing amount of in-service data.

Unpredictable nature of power electronic based renewable energy sources impacts negatively on grid voltage and frequency profile. Energy storage is one of the solutions to overcome fluctuating power generation from renewable energy sources. Shorter life span of energy storage makes it costly. Grid forming control is another solution to overcome fluctuating power generation from renewable energy sources. Grid forming converters can regulate voltage and frequency of existing grid by regulating output active and reactive power. Grid forming converter can also form the grid \u0000for the remote area where the loads are isolated from utility grid. To regulate output active power grid forming converter also require energy storage when utilized with renewable energy sources. High Voltage Direct Current (HVDC) with one of the converters operating under grid forming mode can supply large isolated load. Renewable energy sources which is operating under grid following mode can also be integrated with High Voltage Direct Current (HVDC) with one of the converters operating under grid forming mode.

However, the AI adoption in Jordan is met with cautious progress. AI has shown substantial potential to enhance healthcare services and foster Emotional Intelligence (EI), especially in advanced economies. Despite its proven effectiveness elsewhere, the Jordanian populace is reluctant to adopt AI in the healthcare sector, with predictions for hospitalizations, medical consultations, and treatment recommendations being sluggish to gain acceptance. This study investigates the combination of Emotional Intelligence and AI adoption in the healthcare system in Jordan, guided by the Unified Theory of Acceptance and Use of Technology (UTAUT) model. While UTAUT typically considers performance expectancy, effort expectancy, social influence, and facilitating conditions as key determinants of technology acceptance, this study argues that emotional intelligence, including self-regulated, self-awareness, motivation, empathy, and social skills, should be integrated as direct determinants of behavioural intention. In this study, a quantitative approach has been employed, whereby questionnaires were delivered through email and messaging apps to evaluate the impact of emotional intelligence on Jordanians’ willingness to adopt AI technology in the healthcare sector. The findings suggested that the UTAUT model should be further expanded to encompass emotional intelligence as its fifth construct, particularly in developing countries like Jordan, where user models for AI adoption are less explored. The implications of the study extend to healthcare planners and developers in Jordan, providing insights into factors, which influence the successful adoption of AI technologies among diverse user groups. This study has provided valuable recommendations for developers of AI-based healthcare systems, enabling them to align their assistance with the perceptions and behaviours of Middle Eastern users. By doing so, they can foster increased acceptance of AI-based healthcare systems in the Middle East and other developing regions to improve healthcare services. ","PeriodicalId":44451,"journal":{"name":"Journal of Electrical Systems","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141662443","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}

Climate parameter play important role in efficiency of solar still. Many investigators have investigated the effect of climate parameter to improve the performance of solar still. This review paper evaluates the effect of several climate parameters like wind velocity, ambient temperature, location and vapour pressure. Review was to be done to minimize adverse effect of climate parameter to improve the performance solar still. From this review, it is found that productivity of still increase with increasing wind speed but performance of still little bit decrease with higher wind velocity approximately more than 9 m/s. There is direct relationship between the solar radiation and ambient temperature. The daily productivity increased as ambient temperature increased and directly promotional to the solar radiation. The productivity remains intact during the variation in vapour pressure of surrounding air on solar still. Further, it is found that at low latitude station in India, yearly total radiation and seasonally radiation are approximately equal irrespective of E-W or N-S orientation for double slop single basin solar still. At high latitude, the east-west orientation receives more radiation than the south-north orientation, taking the year as a whole, while there is no effect of orientation in case of lower latitude for double slope single basin solar still.  The single slope solar still single basin facing south collects greater amount of solar radiation as compared to the dual slope single basin solar still at lower and higher latitude locations. Solar still would be kept south facing for northern latitude and north facing for southern latitude.","PeriodicalId":44451,"journal":{"name":"Journal of Electrical Systems","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141835731","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}
