Using five machine learning methods, long-term wind power prediction was done in this study using daily wind speed data. We suggested an effective way to forecast wind power values using machine learning techniques. To demonstrate how machine learning algorithms, perform, we carried out a number of case studies. The outcomes demonstrated that long-term wind power values might be predicted using machine learning algorithms in relation to past wind speed data. Additionally, the consequences show that machine learning-based  Models could be used in places other than those where they were taught. This study showed that, by employing a model of a base site, machine learning algorithms could be applied frequently prior to the development of wind plants in an undisclosed environmental region, provided that it makes sense.

Frequency Domain Backdoor Attacks for Visual Object Tracking 视觉物体跟踪的频域后门攻击
IF 0.5 Q4 ENGINEERING, ELECTRICAL & ELECTRONIC Pub Date : 2024-07-10 DOI: 10.52783/jes.5089

Visual object tracking(VOT)is a key topic in computer vision tasks. 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.
视觉物体跟踪(VOT)是计算机视觉任务中的一个关键主题。它是该领域各种高级问题(如运动分析、事件检测和活动理解)的重要组成部分。VOT 应用广泛,包括视频中的人机交互、视频监控和自动驾驶。由于深度神经网络(DNN)的快速发展,VOT 取得了前所未有的进步。然而,由于深度神经网络缺乏可解释性,因此带来了一定的安全风险,特别是后门攻击。神经网络后门攻击是指攻击者在网络中注入隐藏的后门,使被攻击的模型在正常输入的情况下表现正常,但在满足攻击者设定的特定条件时产生预定的输出。现有的 VOT 后门攻击触发器隐蔽性很差。我们利用 DNN 对微小扰动的敏感性,在频域生成像素级的不可分扰动,从而提出了一种隐形后门攻击。这种方法同时确保了有效性和隐蔽性。此外,我们还采用了微分进化(DE)算法来优化触发器的生成,从而降低攻击者所需的能力。我们在各种数据集和模型中验证了这种攻击的有效性。

Comparison of Control Strategies of Quasi Z-Source Inverter for Wind Power Generation 风力发电准 Z 源逆变器控制策略比较

This paper compares the control strategies of Quasi z source inverter for wind power generation. 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. 
本文比较了风力发电准 z 源逆变器的控制策略。传统风能转换系统中的发电机利用风的动能产生电能。由于风力波动,发电机的输出通过整流器和逆变器连接到负载,以保持负载端电压恒定。两级转换现象有其局限性,即成本高、效率低。Z 源逆变器提供了一种新颖的转换方法,可用于缓解上述限制。不过,它们也有一些缺点,如输入电流不均、浪涌电流大和电压应力高。准 Z 源逆变器 (QZSI) 是一种基于 Z 源逆变器拓扑结构的单级功率转换器,可以克服这些问题。它通过使用一个与源和逆变器耦合的阻抗网络,为风力发电系统提供升压。本文针对风力发电系统,对准 Z 源逆变器的不同控制策略进行了比较研究,以找出一种有效的策略。

For necessary action to be taken in a timely and economical way, accurate service-life forecast of buildings is essential. But the oversimplified assumptions of the traditional prediction models result in approximations that are not correct. The capacity of “machine learning” to overcome the shortcomings of traditional future models is reviewed in this research. 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. In light of the most recent developments and the state of the art in this particular field, the presentation ends by suggesting future directions.

Pollution free renewable energy sources are key solutions for increasing power demand. 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 for 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. In this research work, capability of grid forming converter based HVDC in varying load condition has been verified. To understand the effect of integration of renewable energy with grid forming based HVDC, Doubly Fed Induction Generation (DFIG) based wind turbine has been integrated. To validate the capability of grid forming converter based HVDC modelling has been done in Simulink/MATLAB. Results show that Grid forming converter based HVDC system is capable to fulfil the load demand in varying load/generation condition.   
无污染的可再生能源是满足日益增长的电力需求的关键解决方案。基于电力电子的可再生能源的不可预测性对电网电压和频率曲线产生了负面影响。储能是克服可再生能源发电波动的解决方案之一。储能的寿命较短,因此成本较高。电网形成控制是克服可再生能源发电波动的另一种解决方案。并网变流器可以通过调节输出有功功率和无功功率来调节现有电网的电压和频率。电网形成转换器还可以为偏远地区形成电网,这些地区的负载与公用电网隔离。为了调节输出有功功率,并网变流器在使用可再生能源时还需要储能。高压直流(HVDC)的其中一个变流器在电网形成模式下运行,可为大型隔离负载供电。在电网跟随模式下运行的可再生能源也可以与高压直流(HVDC)结合使用,其中一个变流器在电网形成模式下运行。在这项研究工作中,已经验证了基于电网成形变流器的 HVDC 在不同负载条件下的能力。为了解可再生能源与基于电网成形的 HVDC 的集成效果,已集成了基于双馈感应发电(DFIG)的风力涡轮机。为了验证基于电网成形变流器的 HVDC 能力,我们在 Simulink/MATLAB 中进行了建模。结果表明,基于电网成形变流器的高压直流系统能够满足不同负载/发电条件下的负载需求。

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. In this research work, capability of grid forming converter based HVDC in varying load condition has been verified. To understand the effect of integration of renewable energy with grid forming based HVDC, Doubly Fed Induction Generation (DFIG) based wind turbine has been integrated.

The integration of Artificial Intelligence (AI) has been reshaping healthcare globally. 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. 
人工智能(AI)的融入正在重塑全球医疗保健行业。然而,约旦在采用人工智能方面进展谨慎。人工智能在提升医疗保健服务和促进情感智能(EI)方面已显示出巨大潜力,尤其是在发达经济体。尽管人工智能的有效性已在其他地方得到证实,但约旦民众仍不愿在医疗保健领域采用人工智能,对住院、医疗咨询和治疗建议的预测迟迟未被接受。本研究以技术接受和使用统一理论(UTAUT)模型为指导,调查约旦医疗系统中情感智能与人工智能的结合应用情况。UTAUT通常将绩效预期、努力预期、社会影响和便利条件视为技术接受的关键决定因素,而本研究则认为情商,包括自我调节、自我意识、动机、同理心和社交技能,应作为行为意向的直接决定因素加以整合。本研究采用定量方法,通过电子邮件和信息应用程序发放问卷,评估情商对约旦人在医疗保健领域采用人工智能技术意愿的影响。研究结果表明,UTAUT 模型应进一步扩展,将情商作为其第五个构造,特别是在约旦这样的发展中国家,因为这些国家对人工智能采用的用户模型探索较少。这项研究对约旦的医疗保健规划人员和开发人员具有深远的影响,让他们深入了解影响不同用户群体成功采用人工智能技术的因素。这项研究为基于人工智能的医疗系统开发人员提供了宝贵的建议,使他们能够根据中东用户的认知和行为来调整他们的援助。通过这样做,他们可以促进中东和其他发展中地区更多地接受基于人工智能的医疗保健系统,从而改善医疗保健服务。

Conventional solar still have poor efficiency and low distillate output. 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.
传统的太阳能蒸馏器效率低,蒸馏物产量低。气候参数对太阳能蒸馏器的效率起着重要作用。许多研究人员已经调查了气候参数对提高太阳能蒸馏器性能的影响。本综述论文评估了风速、环境温度、位置和蒸汽压等几个气候参数的影响。研究的目的是尽量减少气候参数对提高太阳能蒸发器性能的不利影响。审查发现,随着风速的增加,蒸馏器的生产率也会增加,但风速超过 9 米/秒时,蒸馏器的性能会略有下降。太阳辐射和环境温度之间存在直接关系。日生产力随着环境温度的升高而提高,与太阳辐射直接相关。在太阳静止时,周围空气蒸汽压力变化时,生产率保持不变。此外,研究还发现,在印度的低纬度站,无论双斜面单盆太阳能蒸发器的朝向是东-西还是北-南,年总辐射量和季节辐射量大致相等。在高纬度地区,从全年来看,东西朝向比南北朝向获得更多辐射,而在低纬度地区,双坡单池太阳能蒸发器的朝向没有影响。 在较低和较高纬度地区,单坡单盆太阳能蒸发器朝南收集的太阳辐射量比双坡单盆太阳能蒸发器大。在北纬地区,太阳能蒸发器应朝南;在南纬地区,太阳能蒸发器应朝北。
