The Internet of Things (IoTs) is apace growing, billions of IoT devicesare connected to the Internet which communicate and exchange data among eachother. Applications of IoT can be found in many fields of engineering and sciencessuch as healthcare, traffic, agriculture, oil and gas industries, and logistics. Inlogistics, the products which are to be transported may be sensitive and perishable, and require controlled environment. Most of the commercially availablelogistic containers are not integrated with IoT devices to provide controlled environment parameters inside the container and to transmit data to a remote *** necessitates the need for designing and fabricating IoT based smart containers. Due to constrained nature of IoT devices, these are prone to different cybersecurity attacks such as Denial of Service (DoS), Man in Middle (MITM) andReplay. Therefore, designing efficient cyber security framework are required forsmart container. The Datagram Transport Layer Security (DTLS) Protocol hasemerged as the de facto standard for securing communication in IoT ***, it is unable to minimize cyber security attacks such as Denial of Serviceand Distributed Denial of Service (DDoS) during the handshake process. Themain contribution of this paper is to design a cyber secure framework by implementing novel hybrid DTLS protocol in smart container which can efficientlyminimize the effects of cyber attacks during handshake process. The performanceof our proposed framework is evaluated in terms of energy efficiency, handshaketime, throughput and packet delivery ratio. Moreover, the proposed framework istested in IoT based smart containers. The proposed framework decreases handshake time more than 9% and saves 11% of energy efficiency for transmissionin compare of the standard DTLS, while increases packet delivery ratio andthroughput by 83% and 87% respectively.

传统的电力系统采用集中控制方式来管理。这样的系统通常被认为是消极的,因为电流只能从电网流动到消费者或负载。能源产业的放松管制和重组以及可再生能源(RE)和其他传统发电机的日益饱和使得研究人员开始研究微电网中的分布式发电机,这改变了电力系统中传统的潮流流动方向。这种系统被认为是主动系统,因为电流可以从分布式电源到电网双向流动。但是,由于管理费用难以控制等问题,集中控制技术不能有效地应用于微电网中的分布式电源,在微电网中控制分布式电源会有一定难度。因此,将采用分散式/分散式控制技术替代集中控制技术。本文主要目的是说明微电网能够以分散控制方式高效,有效地管理微电网。近年来,为了减少二氧化碳的排放,保护环境,微电网中的绿色能源技术的发展得到了广泛的认可。分布式能源资源,例如太阳能热电联产(CHP),太阳能光伏(PV),小型柴油发动机,风力发电机(WT)和燃料电池技术在不断增长。对这些电能的运行控制和维护将会对电力系统产生很大的影响。为了在微电网中实现电能的最佳配置,多代理系统(MAS)技术被提出在分布式层面管理电力系统,并且已经在电力系统中有许多的应用。本文研究基于分布式控制的MAS技术的微电网中分布式电源的控制及其最优配置。最重要的是通过代理系统解决多方面责任问题。当地代理系统将在不受系统中央控制器控制的情况下进行本地决策并执行其各自的任务。因此,整个系统的智能性是通过当地的决策来体现的。此外,代理系统可以对微电网内发生的不稳定或参数变化等情况做出调整。Java代理开发框架(JADE)是多代理系统模拟和显示代理程序性能的实现工具之一,并且符合IEEE智能物理代理基金会(FIPA)标准,可以方便地应用于代理系统中。其次,采用不同的优化方法对MG进行了完全控制。在微电网设计优化中提出了一种三层控制体系结构,该结构具有最小功率损耗的优点。目前基于永磁同步发电机(PMSG)的风能转换系统(WECS)的广泛应用被相关研究人员广泛研究。本文提出一种基于PMSG的WECS的基于分数阶滑动模式(FOAM)功率输出控制方案。基于快指数法的FOAM控制技术被证明能够以更快的收敛速度来衰减振动现象。用于连接PMSG和电网的升压转换器和中性点钳位逆变器均采用提出的FOSM控制方案进行控制。此外,跟踪直接和正交电网电流,对有功和无功功率输出进行控制。所提出的方法的有效性用8k风力涡轮机模拟验证,测试结果表明所提出的方法可以更好地跟踪有功和无功功率的参考值。除此之外,电网电流的总谐波失真水平大大减轻。

Boosting Achene Yield and Yield Related Traits of Sunflower Hybrids through Boron Application Strategies

American Journal of Plant Sciences 2015年第11期6卷 1752-1759页

作者： Imran khan Shakeel Ahmad Anjum Rashad waseem khan Qardri Muqarrab Ali Muhammad Umer Chattha Muhammad Asif Department of Agronomy University of Agriculture Faisalabad Pakistan Institute of Horticultural Sciences University of Agriculture Faisalabad Pakistan Department of Agronomy Muhammad Nawaz Shareef University of Agriculture Multan Pakistan

Effects of different boron (B) application methods on growth and yield of sunflower hybrids were checked out at Agronomic Research Farm, University of Agriculture, Faisalabad, Pakistan during spring, 2013. Field experiment was conducted by considering three sunflower hybrids viz., Patron 551, Patron 851 and S-278 along with different methods of B application i.e. no B application, seed treatment @ 0.05% B, soil B application @ 2 kg·ha-1 at sowing, soil B application @ 2 kg·ha-1 at ray floret stage and foliar application of B @ 200 mg·L-1 at ray floret stage. Uttermost plant height (150.78 cm), the number of leaves per plant (22.67) and stem diameter (1.62 cm) were accomplished when boron was soil applied @ 2 kg·ha-1 at sowing. Significantly higher head diameter (18.30 cm), number of achene per head (1266.44), 1000-achene weight (43.17 g) achene yield (2039.33 kg·ha-1), biological yield (9223.11 kg·ha-1) and harvest index (22.10%) were registered when boron was foliar applied @ 200 mg·L-1 at ray floret stage. Among sunflower hybrids, Patron 551 produced significantly higher growth and yield attributes as compared with Patron 851 and S-278 hybrids. This study suggested that the selection of Patron 551 hybrid with practicing boron foliar application @ 200 mg·L-1 at ray floret stage could be helpful in achieving the sunflower crop genetic potential.

Design of CsI(TI) detector system to search for lost radioactive source

引用

Nuclear Science and Techniques 2019年第9期30卷 9-17页

作者： waseem khan Chao-Hui He Qing-Min Zhang Yu Cao Wei-Tao Yang Department of Nuclear Science and Technology School of Energy and Power Engineering Xi’an Jiaotong University

This report presents a design system based on the use of CsI(TI) detectors to search for lost radioactive sources that are dangerous and harmful to individuals, including searching persons. For this purpose, the GEANT4 simulation toolkit was utilized to develop a system based on three detectors. Various simulated analyses were performed on the dose rates of the three detectors using different source–detector distances and detector separation. There were good agreement between the simulated results and the experimentally measured data. A new method was discussed to detect and search for radioactive sources based only on the dose rates in detectors with source activity. Numerical analyses were performed based on the measured dose rates and the difference of distances to determine the actual location of the lost single or multiple γ-ray sources at a specific angle. The detection limit was calculated from the background radiation to establish the sensitivity and capability of the proposed detector system. This system can be applied in fields in which it is necessary to locate unknown radioactive sources.
