Muhammad Umer, Ayaz Akbar, Saad Dilshad, Umer Javed Kalair, N. Abas
Energy demands and costs are amplified by the escalation of population, the depletion of fossil fuels, economic growth, and the adoption of energy-intensive lifestyles. Hence, the need for eco-friendly solar thermal systems for water and space heating surges, as solar energy exhibits numerous positive environmental impacts. With the help of thermal collectors and solar cells, one can immediately receive heat and power from the sun. Solar water heating systems are among the most popular solar thermal applications. The current investigation executes the solar thermal water heating system analysis for Lahore, Karachi, Multan, and Peshawar, four major Pakistani cities, considering the thermal proficiency of flat plate collector solar water heating system. Various factors are assessed, such as the auxiliary energy source, solar fraction, and the quantity of heat energy supplied by solar collector for heating water. The amount of auxiliary energy required to fulfill the heat energy demand is recorded as maximum in January for Lahore, Multan, and Peshawar but for Karachi, it is maximum in July. It is observed that due to the presence of the Arabian sea, the climatic conditions of Karachi differ from other cities. According to the findings, it is observed that the proposed system is suitable for Lahore, Karachi, Multan, and Peshawar in respective order.
人口的增长、化石燃料的枯竭、经济的增长以及能源密集型生活方式的采用,都加剧了能源的需求和成本。因此,由于太阳能具有许多积极的环境影响,对水和空间加热的生态友好型太阳能热系统的需求激增。在集热器和太阳能电池的帮助下,人们可以立即接收来自太阳的热量和能量。太阳能热水系统是最受欢迎的太阳能热应用之一。本次调查对巴基斯坦的拉合尔、卡拉奇、木尔坦和白沙瓦四个主要城市的太阳能热水系统进行了分析,考虑了平板集热器太阳能热水系统的热能力。评估了各种因素,如辅助能源、太阳能分数和太阳能集热器为加热水提供的热能量。在拉合尔、木尔坦和白沙瓦,满足热能需求所需的辅助能源量在1月份达到最大值,但在卡拉奇,辅助能源量在7月份达到最大值。据观察,由于阿拉伯海的存在,卡拉奇的气候条件不同于其他城市。根据研究结果,所提出的系统依次适用于拉合尔、卡拉奇、木尔坦和白沙瓦。

Intelligent Systems for Early Malaria Disease Detection in Patient Cells Using Transfer Learning Approaches 使用迁移学习方法在患者细胞中进行疟疾早期检测的智能系统
Gul Zaman Khan, Ibrar Ali Shah, Farhatullah, Muhammad Abul Hassan, Hazrat Junaid, Fouzia Sardar
Malaria is an infectious disease spread by mosquitoes that effect humans and other animals. It is a massive threat to humanity, with instances growing each year. It is essential to prevent and diagnose malaria immediately and efficiently. For the time being, conventional methods are used for diagnosing malaria in which the patient's blood sample is examined by microscope or by using malaria RTD kits. This approach has several limitations because it requires medical expertise, is expensive, takes a long time, and the results are unsatisfactory. Artificial intelligence-based systems can prevent and help in diagnose of this infectious disease. Because of these limitations, the proposed work has proposed an AI-based diagnosis system that can detect malaria parasites immediately and efficiently. In the proposed experiment, we have applied four different pre-trained deep learning models on the image dataset with some preprocessing and optimization techniques for malaria parasite detection. After investigations, evaluation matrices such as precision, Recall, F1-score, sensitivity, and specificity are used to measure the performance of the proposed models. The Inception-Resnet outperformed by achieving 95% accuracy, VGG16 achieved 92% accuracy, inception achieved 93% accuracy, and VGG19 achieved 91% accuracy. The positive outcomes of this study show that this approach performs much better than the approaches currently used. Furthermore, the proposed method is relevant to health experts for screening purposes.
疟疾是一种由蚊子传播的传染病,影响人类和其他动物。这对人类是一个巨大的威胁,而且每年都在增加。必须立即和有效地预防和诊断疟疾。目前,用于诊断疟疾的常规方法是通过显微镜或使用疟疾RTD试剂盒检查患者的血液样本。这种方法有几个局限性,因为它需要医学专业知识,价格昂贵,耗时长,结果不令人满意。基于人工智能的系统可以预防和帮助诊断这种传染病。由于这些限制,本研究提出了一种基于人工智能的诊断系统,可以立即有效地检测疟疾寄生虫。在实验中,我们在图像数据集上应用了四种不同的预训练深度学习模型,并采用了一些预处理和优化技术来检测疟疾寄生虫。经过调查,评估矩阵如精度,召回率,f1评分,敏感性和特异性被用来衡量所提出的模型的性能。inception - resnet达到了95%的准确率,VGG16达到了92%的准确率,inception达到了93%的准确率,VGG19达到了91%的准确率。本研究的积极结果表明,该方法比目前使用的方法性能要好得多。此外,拟议的方法与卫生专家进行筛查有关。

A New Method of Unintentional Islanding detection for Multiple Distributed energy resources based Power System 基于多分布式能源的电力系统意外孤岛检测新方法
Nauman Ali Larik, Muneer Ahmed, L. L. Zhang, Jawed Ahmed Jamali, Q.H. Wu
Distributed generation (DG) is being integrated into power systems worldwide to reduce fossil fuel consumption and avoid the expense of transmission lines. In addition to the aforementioned benefits, it also poses issues for protection co-ordination, power quality, and the establishment of an islanding condition that must be resolved for proper operation and seamless transition of mictrogrid in islanding mode to perserve reliability. Islanding is an unwanted state that can pose safety risks to utility workers, power system equipments, and customer devices. In this paper, severe consequences of unintentional islanding are discussed and a ROCOF based method for islanding detection for multiple energy resources based system is proposed. Simulation results considering different normal and islanding cases are exhibited, which proves fast detection with effectiveness and accuracy of the proposed method.
分布式发电(DG)正在被整合到世界各地的电力系统中,以减少化石燃料的消耗并避免输电线路的费用。除了上述好处之外,它还带来了保护协调、电能质量和孤岛条件的建立等问题,这些问题必须得到解决,才能使微电网在孤岛模式下正常运行和无缝过渡,以保持可靠性。孤岛是一种不受欢迎的状态,它会给公用事业工人、电力系统设备和客户设备带来安全风险。本文讨论了非故意孤岛的严重后果,提出了一种基于ROCOF的多能源系统孤岛检测方法。给出了不同正常情况和孤岛情况下的仿真结果,验证了所提方法的快速检测、有效性和准确性。

Automatic Solar Based Water Heating System Through Convex Lenses 通过凸透镜的自动太阳能热水系统
Abdul Samim, Narjis, Abdul Rafay Khatri
In this investigation, convex lenses are used to study the performance and heat transfer analysis of solar grounded water heating systems. The employment of convex lenses, which concentrate solar radiation on the water layers at a single spot, is favored when using diffusible radiation. The tank benefits from receiving sun radiation. The water is possible to absorb high heat from the lens arrays attributable to lenses that are attached over the top and fasten radiations that prompt to the working fluid. In this instance, lenses are used to investigate the properties of heat. This endeavor demonstrates the exploration of the potential usage of a convex lens for a solar-powered water heating system. The objective of this exploratory research is to develop a water heating system using convex lenses that is completely dependent on solar radiation in order to save the electricity, gas, and reactive energy that are utilized by geysers and for other common living uses. When employing diffusible radiation, it is preferred to use convex lenses since they focus solar energy on the water layers at a particular location.
在本研究中,凸透镜用于研究太阳能地热水系统的性能和传热分析。当使用扩散辐射时,凸透镜的使用是有利的,它将太阳辐射集中在单个点的水层上。这个水箱受益于接受太阳辐射。由于安装在顶部的透镜阵列,水可以吸收来自透镜阵列的高热量,并将辐射固定在工作流体上。在这种情况下,透镜被用来研究热的性质。这一努力展示了凸透镜在太阳能热水系统中潜在用途的探索。这项探索性研究的目的是开发一种使用凸透镜的热水系统,该系统完全依赖于太阳辐射,以节省间歇泉和其他常见生活用途所使用的电力、天然气和反应能量。当采用扩散辐射时,最好使用凸透镜,因为它们将太阳能聚焦在特定位置的水层上。

Degradation of Silicon Rubber-based Nuclear Power Plant I&C Cable under Accelerated Thermal Aging 加速热老化作用下硅橡胶基核电厂I&C电缆的降解
U. Ibrahim, Iftikhar Ahmed, Naveed Ahmed, Abdul Rehman Abbasi, E. Mustafa, Hafeez Ullah
The degradation behavior of SiR-insulated cable samples under accelerated thermal stress has been investigated in this research work. The cable samples were taken from NPP-based I&C cable and were exposed to 155°C for three aging cycles. The variation in the insulation was evaluated by applying dielectric spectroscopy in the frequency range of 1kHz to 5 MHz where the capacitance and tanδ were investigated. Microhardness was also adapted to help elucidate the degradation in the insulation. The effect of thermal aging was observed in the form of a chemical cross-linking reaction as at most of the frequency points the tanδ and capacitance values decreased. The microhardness results also reflected the degradation of the SiR material, where the hardness of the material decreased with aging.
本文研究了sir绝缘电缆试样在加速热应力作用下的降解行为。电缆样品取自npp基I&C电缆,并在155°C下进行3次老化循环。在1kHz ~ 5mhz的频率范围内,采用介电光谱法对绝缘变化进行了评价,并对电容和tanδ进行了研究。显微硬度也适用于帮助阐明在绝缘的退化。热老化的影响以化学交联反应的形式出现,在大多数频率点,tanδ和电容值都降低了。显微硬度结果也反映了SiR材料的退化,材料的硬度随着时效而降低。

Dual Auction Peer-to-Peer Control Scheme for Empowering Prosumers Participation in the Local Energy Markets 授权产消参与本地能源市场的双重拍卖点对点控制计划
Muhammad Ikram, Salman Ahmed, Safdar Nawaz Khan Marwat
The emerging trend of distributed and renewable energy sources encourages energy trading in the electricity market. Various forms of energy markets are evolving for successful energy trading. The local energy market is one of them in which various participants are actively coordinating for optimal utilization of power. Such type of local energy markets provides individual prosumers to trade their surplus energy in the neighbourhood in peer-to-peer topology. The complexity of such type of local energy market is increasing in terms of structure, control, coordination, and cost estimation. For the cooperative behaviour of the local energy markets, a dual auction coordination control scheme is important to encourage more prosumers for energy trading. We proposed a novel scheme that performs dual auctions for prosumers in a decentralized fashion. We assessed dual auction matching by coordinating prosumers and consumers to sell and purchase energy in the local energy market. The aggregator performed balancing in the proposed dual auction scheme as an autonomous entity. The results were simulated in MATLAB and JADE for the complex prosumer peer-to-peer network. Our proposed scheme shows each peer dual auction matching improves from 0.95 to 2.03 for optimal hierarchal energy trading in energy markets. For peer participation, the participation ratio increased from 0.684 to 1.74 and optimal aggregator coordination from 9.18% to 19% in the local energy markets.
分布式和可再生能源的新兴趋势鼓励了电力市场的能源交易。为了成功的能源交易,各种形式的能源市场正在发展。当地的能源市场就是其中之一,在这个市场中,各个参与者都在积极协调,以实现电力的最佳利用。这种类型的本地能源市场以点对点的拓扑结构为个体生产消费者提供了在邻近地区进行剩余能源交易的机会。这种类型的地方能源市场在结构、控制、协调和成本估算方面的复杂性正在增加。对于地方能源市场的合作行为,双重拍卖协调控制方案对于鼓励更多的生产消费者进行能源交易是重要的。我们提出了一种新颖的方案,以分散的方式对产消者进行双重拍卖。我们通过协调生产消费者和消费者在当地能源市场上买卖能源来评估双重拍卖匹配。聚合器作为一个自治实体在所提出的双拍卖方案中执行平衡。在MATLAB和JADE中对复杂的产消点对点网络进行了仿真。我们提出的方案表明,在能源市场的最优分层能源交易中,每个节点的双拍卖匹配从0.95提高到2.03。对于同伴参与,本地能源市场的参与率从0.684提高到1.74,最优聚合器协调从9.18%提高到19%。

Such type of local energy markets provides individual prosumers to trade their surplus energy in the neighbourhood in peer-to-peer topology. The complexity of such type of local energy market is increasing in terms of structure, control, coordination, and cost estimation. For the cooperative behaviour of the local energy markets, a dual auction coordination control scheme is important to encourage more prosumers for energy trading. We proposed a novel scheme that performs dual auctions for prosumers in a decentralized fashion. We assessed dual auction matching by coordinating prosumers and consumers to sell and purchase energy in the local energy market. The aggregator performed balancing in the proposed dual auction scheme as an autonomous entity. The results were simulated in MATLAB and JADE for the complex prosumer peer-to-peer network. Our proposed scheme shows each peer dual auction matching improves from 0.95 to 2.03 for optimal hierarchal energy trading in energy markets. For peer participation, the participation ratio increased from 0.684 to 1.74 and optimal aggregator coordination from 9.18% to 19% in the local energy markets.","PeriodicalId":369792,"journal":{"name":"2023 4th International Conference on Computing, Mathematics and Engineering Technologies (iCoMET)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128980788","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}

Deep Learning-Based Identification of Skin Cancer on Any Suspicious Lesion 基于深度学习的皮肤癌可疑病灶识别
Muhammad Aaqib, Musawir Ghani, Ayaz Khan
Certain estimates place skin cancer as the most lethal form of the disease worldwide. Spreading to other parts of the body and requiring invasive procedures like chemotherapy and radiation therapy are the results of delayed diagnosis. As a result, automatic methods have greatly aided medical professionals and allowed even non-specialists to identify the sort of cancer a patient has. In this paper, we present a deep learning-based skin cancer identification to classify images of skin lesions as malignant or benign. This method may be used for any potentially malignant lesion. We found that using a deep learning (DL) approach that relied on a mask region-based convolutional neural network yielded the fastest and most accurate results for diagnosing skin cancer.
某些估计将皮肤癌列为世界上最致命的疾病。癌症扩散到身体的其他部位,需要进行化疗和放疗等侵入性手术,这些都是诊断延误的结果。因此,自动方法极大地帮助了医疗专业人员,甚至允许非专业人员识别患者所患的癌症类型。在本文中,我们提出了一种基于深度学习的皮肤癌识别方法,将皮肤病变图像分类为恶性或良性。这种方法可用于任何潜在的恶性病变。我们发现,使用基于掩模区域的卷积神经网络的深度学习(DL)方法,在诊断皮肤癌方面产生了最快、最准确的结果。
