the cluster heads (CHs) are distributed randomly in the Low Energy Adaptive Clustering Hierarchy (LEACH) protocol. Some sensor nodes may be placed further away from the CHs and thus are not covered. This causes excessive route energy consumption of the isolated nodes. Because of randomly selecting the CHs, some nodes can die quickly due to extra workload. By used Spider Monkey Optimization (SMO), we can elect the CHs and design cluster-based routing algorithms. The SMO looks for the social behaviors of spider monkeys to choose the optimal route. The social behaviors are an example of the fission-fusion system. In this paper, we proposed the Selection Optimal of Cluster Head Based Spider Monkey Optimization (OCHSMO) algorithm. The proposed algorithm has used the mechanism of the SMO to solve the problems of cluster routing in the WSNs. It improves the LEACH protocol in terms of energy consumption, system lifetime, stability period, and system quality of the network. Experimental results show that the OCHSMO algorithm is better than the LEACH algorithm in all performance measures. We used the MATLAB to evaluate the performance.
在低能量自适应聚类层次(LEACH)协议中,簇头是随机分布的。一些传感器节点可能被放置在远离CHs的地方,因此没有被覆盖。导致被隔离节点路由能耗过大。由于随机选择CHs,一些节点可能会由于额外的工作负载而迅速死亡。利用蜘蛛猴优化算法(SMO)来选择CHs并设计基于聚类的路由算法。SMO通过寻找蜘蛛猴的社会行为来选择最优路线。社会行为是裂变融合系统的一个例子。本文提出了基于簇头的蜘蛛猴优化算法(OCHSMO)。该算法利用SMO机制解决了无线传感器网络中的集群路由问题。从网络的能耗、系统寿命、稳定周期和系统质量等方面对LEACH协议进行了改进。实验结果表明,OCHSMO算法在各性能指标上都优于LEACH算法。我们使用MATLAB对其性能进行了评估。

The antenna has a size of $40 times 41 times 1.6$ mm3, printed on FR-4 dielectric material with height (h) of 1.6 mm, loss tangent () of 0.02 and dielectric constant () of 4.4. Antenna parameters such as return loss (), gain, voltage standing wave ratio (VSWR), radiation pattern were simulated and analyzed. The antenna has two frequency bands. The first band (2.74GHz - 7.48GHz) in which the antenna resonates at frequencies, 3.37 GHz, 5.15 GHz, 6.64 GHz, 7.4 GHz and the second band (8.23 GHz - 9.8 GHz) with a center frequency at 9 GHz. Fractional bandwidths (< -10 dB) of 140%, 91.8%, 71.7% and 63.9% in the first band and 15.9% in the second band were achieved respectively. Furthermore, 3.3 dBi, 3.5 dBi, 3.244 dBi, 3.437 dBi and 3.937 dBi were provided at the resonant frequencies respectively. The simulation and numerical analysis were carried out using HFSS software.

A broadband electromagnetic metasurface (MS) absorber with a wide-angle coverage is designed and discussed for energy harvesting applications. The proposed MS absorber consists of two split-ring resonators (SRR) forming an X-shaped in the middle and layout is designed on FR4 dielectric substrate. An air gap layer is separated between the dielectric substrate and a ground plane. At normal incidence, the proposed MS structure achieves a higher absorption ratio (>90%) with a 10-dB impedance bandwidth of more than 4 GHz (2.14 GHz-6.4 GHz). For oblique incidence, greater than 85% absorptivity is observed from $0^{circ}, to 30^{circ}$ across the frequencies range from 2.14 GHz to 6.4 GHz. Two higher absorption peaks of more than 80% at 2.4 GHz and from 5 GHz to 6.5 GHz for TEM polarization are achieved respectively at 45° and 60°. Furthermore, the absorption mechanism is numerically demonstrated in detail.

Self-service terminal equipment generally, compose of group of integrated systems, which operate together to offer services to human in the economic aspect. The conception of the self-service store terminal equipment facilitates person's life, greatly. The self- service terminal equipment that exist in Yemen are rarely found, because of their extremely expensive cost. Additionally, that material can't deal with all denominations of Yemeni paper currency; just two denominations can be treated. The proposed system is a Mechatronics' system which typifies a prototype of SST equipment which is able to arrangement with all denominations of Yemeni paper currency. The principal function of the proposed scheme is building up an SST prototype with simple social system which is able to recognize and detect four denominations of Yemeni paper currency (1000, 500, 200 and 100 Yr), then store them in the specified box for each denomination. The proposed scheme is composed of four integrated systems as work together concurrently. The entered paper currency is fed into the detection place to be determined whether it is fake or genuine, then if it is genuine, it will be recognized to identify its denomination, finally it is stored in the specified box according to the currency denomination. The identification scheme has been designed to distinguish the dominant colour in each denomination using color sensor, while the detection scheme is designed using the UV - light detector. The developed system has been tested using 10 samples of each denomination for checking the accuracy and speed of operation. The prototype has achieved a high accuracy with short time of processing.

The Internet of Things (IoT) is defined as a potentially effective means of integrating multiple technologies to support the oil and gas (O&G) sector as a network of physical objects connected to the Internet. In Yemen, O&G organizations can embedded vehicles, equipment, buildings, fire siren and wells with electronics, software, sensors, and network connectivity that is now evolving. It is assumed that in one way or another, everything should be connected to one network to ease processes of business. To make IoT a reality, and not only remain academic, O&G sector must be able to engage in and pick up this technology in its day-to-day activities. Several studies have explored IoT’s potential for numerous organizations. However, IoT remains inadequately applied by organizations, including O&G sectors in developing countries. This article attempts to identify the factors that influence users to adopt IoT in the O&G sector in Yemen. Based on a study of prior tests, drivers were identified. Furthermore, a framework is proposed based on information system adoption theory which is the technology-organization-environment (TOE). Partial least squares structural equation modeling (PLS-SEM) has become a popular tool for analyzing such relationships is applied to a survey of 390 IoT users, with results indicating that the factors selected in this study significantly affected the IoT adoption in the Yemeni O&G sector. This study is enabling O&G organizations to understand the factors of IoT adoption, to improve their framework of business and investment in IoT and to inspire researchers to continue research into other IoT adoption or implementation factors.
物联网(IoT)被定义为一种整合多种技术的潜在有效手段,以支持石油和天然气(O&G)行业作为连接到互联网的物理对象网络。在也门,油气公司可以在车辆、设备、建筑、消防警报器和油井中嵌入电子设备、软件、传感器和网络连接,这些都是目前正在发展的技术。假设所有东西都应该以某种方式连接到一个网络,以简化业务流程。为了使物联网成为现实,而不仅仅是停留在学术层面,油气行业必须能够在日常活动中参与并采用这项技术。一些研究已经探索了物联网在众多组织中的潜力。然而,物联网在包括发展中国家油气行业在内的组织中的应用仍然不足。本文试图确定影响用户在也门油气行业采用物联网的因素。基于对先前测试的研究,确定了驾驶员。在此基础上,提出了基于信息系统采用理论的技术-组织-环境(TOE)框架。偏最小二乘结构方程模型(PLS-SEM)已经成为分析这种关系的流行工具,应用于对390个物联网用户的调查,结果表明,本研究中选择的因素显著影响了也门油气行业的物联网采用。这项研究使油气组织能够了解物联网采用的因素,改善他们在物联网方面的业务和投资框架,并激励研究人员继续研究其他物联网采用或实施因素。

Traffic signs are a vital tool of the transport system because they serve to keep pedestrians and drivers readily informed that they can be alerted and notified. Thus, different traffic sign recognition systems were found in the last few years. It is implied that their identification and recognition is a confined issue that signs may be special, distinctive functions, or fragile shapes and solid shapes. Some recent and effective approaches of traffic sign detection and classification showed the success of using deep neural networks in this field. In terms of this domain, the development of an accurate real-time traffic signs recognition system is still a challenging task. This paper discusses the recognition system of traffic signs using four dense CNN-based models, DenseNet121, DenseNet161, DenseNet169, and DenseNet201. However, the present study aims mainly at evaluating the performance of the proposed system using deep dense neural networks on recognizing traffic signs. Results show the feasibility of using DenseNet pre-trained models to perform this task. In terms of testing accuracy, DenseNet201 achieved the best performance with 99.7%.
交通标志是交通系统的一个重要工具,因为它们可以随时通知行人和司机,他们可以得到警报和通知。因此,在过去的几年里,不同的交通标志识别系统被发现。这意味着它们的识别和识别是一个有限的问题,标志可能是特殊的、独特的功能,也可能是脆弱的形状和坚实的形状。近年来一些有效的交通标志检测和分类方法表明,深度神经网络在该领域的应用取得了成功。在这一领域,开发准确的实时交通标志识别系统仍然是一项具有挑战性的任务。本文采用DenseNet121、DenseNet161、DenseNet169和DenseNet201四个基于cnn的密集模型对交通标志识别系统进行了讨论。然而,本研究的主要目的是评估所提出的系统使用深度密集神经网络识别交通标志的性能。结果表明,使用DenseNet预训练模型执行该任务是可行的。在测试精度方面,DenseNet201达到了99.7%的最佳性能。

Protection of the user is the one of primary points within the coming of 5G portable communications. Area protection has recently been broadly tended to within the writing as crucial tricky issues for the client security. The area protection has moreover been tended to in realeases in versatile eras guidelines. In LTE release 13, the proposal is to utilize pseudonyms such as Cell Radio Network Temporary Identifiers (C-RNTI) rather than permanent identity for protecting area security. The point of this paper is to assess the 3GPP security design and propose a protection capability for protecting area security of the 5G design. The proposed strategy is based on presenting modern variable nom de plumes that can supplant the settled Cell- Radio Network Temporary Identifier (C-RNTI) and in cruel times keep up the compatibility with the standard. The proposed arrangement employments an Identity-Division Multiplexing (IDM) strategy to guarantee the unlinkability and untraceability of the client and to avoid aggressors from following or distinguish clients through C-RNTI personalities. The plot gives secure and viable area administration regarding the security of client security in 5G. The conspire is formally confirmed of satisfactory ensure of user’s area security assurance by utilizing ProVerif.
对用户的保护是5G移动通信即将到来的首要问题之一。区域保护最近被广泛地倾向于在写作中作为客户安全的关键棘手问题。此外,区域保护已趋向于在通用时代准则的发布中。在LTE版本13中,建议使用假名,如蜂窝无线网络临时标识符(C-RNTI),而不是永久标识,以保护区域安全。本文的重点是对3GPP的安全设计进行评估,提出一种保护5G设计区域安全的防护能力。该策略的基础是提供现代可变标识符,以取代现有的蜂窝无线网络临时标识符(C-RNTI),并在恶劣的环境下保持与标准的兼容性。该协议采用身份分割复用(Identity-Division Multiplexing, IDM)策略来保证客户端的不可链接性和不可追溯性,避免攻击者通过C-RNTI人格跟踪或区分客户端。该方案为5G客户端安全提供了安全可行的区域管理。利用ProVerif正式确认了该合谋对用户区域安全保障的满意保证。
