Power Management Units (PMU) are rapidly being developed to provide a significant amount of power for sensors in Internet-of-Things (IoT) networks. This paper presents a novel optimized PMU design for IoT applications, which can be used as a part of energy harvesting system that can be composed of solar cells, wind turbine, thermal energy, and vibration. Hence the proposed design can be used as a feasible energy harvester, where notable power efficiency is achieved here over traditional PMU designs under the same circumstances. The optimized PMU is developed using a buck-boost DC-DC converter. The particle swarm optimization (PSO) is then applied to optimize the parameters of PMU, including buck-boost DC-DC converter, and control circuitry to achieve maximum power point and improve the overall efficiency.

In this study, a dynamic weighted round robin call admission (DWRR-CAC) scheme is proposed as an improvement to the recently proposed weighted round robin call admission (WRR-CAC) which reduces new connection blocking rate but wastes network resources due to the fixed reservation and degradation mechanisms it deploys. The DWRR-CAC algorithm solves the problem of resource wastage by deploying three mechanism: a precheck, dynamic degradation, and weight computer mechanism. First it admits all connections based on their maximum sustained traffic rate (MSTR) when the network resources are underutilized. Next, when the available resources are not sufficient to admit new connections, it deploys a pre-check mechanism to determine whether degrading existing non-UGS connections will yield sufficient bandwidth to admit the new connection or not. If the check is passed, the scheme deploys a dynamic degradation mechanism which degrades only existing non-UGS connections to admit the new connections as the non-UGS connections have adaptive QoS requirements but the UGS connections do not. The dynamic degradation mechanism ensures that only the required bandwidth is degraded. If the check fails, the connections are queued according to their traffic classes and retried after some resources are adapted from completed calls. The queued connections are admitted based on the computed WRR weight. Several simulation experiments were conducted to evaluate the performance of the DWRR-CAC against QOGCAC and WRR-CAC using a discrete event simulator. The results show that DWRR-CAC out performs the benchmark schemes in terms of call blocking rate, average and per-flow throughput.
本文提出了一种动态加权轮循呼叫准入(DWRR-CAC)方案,作为最近提出的加权轮循呼叫准入(WRR-CAC)方案的改进,该方案减少了新连接阻塞率,但由于部署了固定的保留和退化机制而浪费了网络资源。DWRR-CAC算法通过部署预检机制、动态退化机制和权重计算机机制来解决资源浪费问题。首先,当网络资源未充分利用时,它根据最大持续流量速率(MSTR)接纳所有连接。接下来,当可用资源不足以接收新连接时,它部署一个预检查机制,以确定降级现有的非ugs连接是否会产生足够的带宽来接收新连接。如果检查通过,则部署动态降级机制,该机制只降级现有的非UGS连接,以允许新的连接,因为非UGS连接有自适应的QoS要求,而UGS连接没有。动态降级机制确保只降级所需的带宽。如果检查失败,则根据其流量类对连接进行排队,并在从已完成的呼叫中调整某些资源后重试。根据计算出的WRR权重允许排队的连接。利用离散事件模拟器对DWRR-CAC与QOGCAC和WRR-CAC的性能进行了仿真实验。结果表明,DWRR-CAC在呼叫阻塞率、平均吞吐量和单流吞吐量方面优于基准方案。

Communication technology facilitates provision of such services as file transferring, print sharing, video streaming. Internet is a global system of interconnected networks. Computer communication networks are based on a technology that provides the technical infrastructure, where routing protocols are used to transmit packets across the internet. Routing protocols specify how routers communicate with each other by disseminating information. Routing protocols are broadly categorized into Interior and Exterior Gateway routing protocols. While Interior Gateway protocols disseminate packets within an Autonomous System (AS), Exterior Gateway protocols send packets from an AS to another. This work review the performance of Interior Gateway Protocols; EIGRP, OSPF, RIP and IS-IS. Considering so many performance metrics like convergence, scale of networks, HTTP page response and packets loss, comparative analysis of the protocols is done.
通信技术促进了诸如文件传输、打印共享、视频流等服务的提供。互联网是一个全球性的互联网络系统。计算机通信网络基于一种提供技术基础设施的技术,其中路由协议用于在互联网上传输数据包。路由协议规定了路由器如何通过传播信息相互通信。路由协议大致分为内部网关路由协议和外部网关路由协议。当内部网关协议在自治系统(AS)内分发数据包时,外部网关协议将数据包从一个自治系统发送到另一个自治系统。本文综述了内部网关协议的性能;EIGRP、OSPF、RIP和IS-IS。考虑到许多性能指标,如收敛、网络规模、HTTP页面响应和数据包丢失,对协议进行了比较分析。

Vote theft and fraud is a deliberate activity which is predominantly perpetrated at every level of electoral process by misrepresenting the actual value of vote count either manually or electronically. The emergence of technology within voting system remains a welcome development because of the comfort and speed it offer, however remains vulnerable to cyber-attack and has failed to deliver a trusted and reliable system. Therefore, blockchain technology in this paper is proposed at election result collation stages to ensure that result counted remains unchanged from the lower collation edge to the final stage of collation and announcement. In this paper, we examine the influence of technology on electoral system, e-voting system its pros and cons, which forms the basis for undertaking this work and the blockchain technology and its application of election result collation.

Hydro generation is the second contributor to the power generation in Nigeria. Nigeria is endowed with abundance of water resources, which over the years has been under harnessed. Hydroelectricity contributes about 30% of the total installed grid in the country. The country has a total installed capacity of 1975MW hydro generated electricity, which will improve immensely over the years, with the proposed construction of new plants. The number of hydropower plants that can be built is finite, but only a third of the sites classified worldwide as economically feasible are tapped. Hydro generation has had so many impacts on the society and environment over the years. These impacts are both positive and negative. This paper looks on the generation of hydropower in Nigeria, its social and environmental impact.
水力发电是尼日利亚发电的第二大来源。尼日利亚拥有丰富的水资源,多年来一直在加以利用。水力发电约占全国已安装电网总量的30%。该国水力发电的总装机容量为1975MW,随着新电厂的建设,这一容量将在未来几年内大幅提高。可建水电站的数量是有限的,但在世界范围内被列为经济可行的地点中,只有三分之一得到了利用。多年来,水力发电对社会和环境产生了许多影响。这些影响既有积极的一面,也有消极的一面。本文着眼于尼日利亚水力发电及其对社会和环境的影响。

Walling materials are essential element of sustainable housing delivery. It influences a wide range of social, economic and environmental factors in any structure. Nigeria has suffered several building collapse with traumatic outcomes and among the major causes is poor building materials. This work studied the performance of Compressed Laterite Blocks (CLB) and compares it with cement block produced under laboratory conditions as well as those sold by block making industries in Abuja. The objective of this study was to determine the geotechnical properties of the laterite soil types for block making and investigate the performance of the block types. Geotechnical tests were conducted on the laterite samples and they were stabilized at different cement contents (0-8%) and compacted. The performance factors; wet and dry compressive strength, density, water absorption were then determined. A cement content of 6.5% for the stabilized laterite blocks yielded the compressed earth blocks with the most desired characteristics. These characteristic surpasses the ones observed for the standard cement blocks as well as those sold commercially in Abuja. Already computer simulation and modelling is being considered as a faster and cost effective way to determine suitability of laterite soil for block making.
墙体材料是可持续住房交付的基本要素。它影响着任何结构中广泛的社会、经济和环境因素。尼日利亚发生了几次建筑物倒塌,造成了创伤性后果,其中一个主要原因是建筑材料不佳。这项工作研究了压缩红土块(CLB)的性能,并将其与实验室条件下生产的水泥块以及阿布贾砌块制造行业销售的水泥块进行了比较。本研究的目的是确定用于砌块的红土土类型的岩土力学特性,并研究砌块类型的性能。对红土试样进行了不同水泥掺量(0 ~ 8%)下的稳定和压实试验。性能因素;然后测定湿、干抗压强度、密度、吸水率。稳定红土块体水泥掺量为6.5%时,得到的压缩土块体具有最理想的特性。这些特性超过了在标准水泥块以及在阿布贾商业销售的水泥块所观察到的特性。计算机模拟和建模已经被认为是确定红土是否适合砌块的一种更快、更经济的方法。

Computer-Based Examination (CBE) is an emerging paradigm for the assessment and measurement of knowledge and capabilities. It relies on computer and its associated technologies to provide solution to some of the problems inherent to human-based approaches to conduct of examinations and invigilation. Such problems include connivance, impersonation, external sourcing and peeking. This paper presents the design of a fingerprint, iris and voicebased framework for promoting the security and reliability of CBE. The proposed framework comprises of modules for CBE, e-invigilation and control. The CBE module module comprises of a network backbone, a server and several workstations. The e-invigilation module is designed to use high definition and resolution iris scanners such as IrisShield-USB MK and CMITech BMT series to capture the iris image of the candidates for processing as well as voice recording and processing devices. The control module is designed to handle fingerprint-based authentication of examinees, process monitoring and relaying of situation reports.
基于计算机的考试(CBE)是一种评估和衡量知识和能力的新兴范式。它依靠计算机及其相关技术来解决一些固有的问题,以人为本的方法来进行考试和监考。这些问题包括纵容、冒充、外部资源和偷窥。为了提高CBE的安全性和可靠性,本文设计了一个基于指纹、虹膜和语音的框架。该框架由CBE、电子监考和控制模块组成。CBE模块由一个网络主干网、一台服务器和几个工作站组成。电子监考模块设计使用高清晰度和分辨率虹膜扫描仪,如IrisShield-USB MK和CMITech BMT系列,以捕获候选人的虹膜图像进行处理,以及录音和处理设备。控制模块主要负责考生指纹认证、过程监控和情况报告的传递。

In cloud computing, Service rendering is achieved through virtualization and the use of very large scalable resources where users access services by paying for the share of resources used by them. Several workflow scheduling techniques have been proposed for efficient scheduling. Max-min approach is prominent among them, its features includes efficiency and the ability to guarantee optimal or near optimal solution because of its heuristic nature. Several enhancement to its functionalities have been proposed in the literature and works are still ongoing for improving it. This paper proposed a solution by minimizing total execution time where workflow tasks length are invariably considered before proper scheduling. Our proposed work is compared with standard Max-Min scheduling scheme. The proposed scheme outperforms the standard scheme; two realistic scientific workflows were used as test data for the simulation.
在云计算中,服务呈现是通过虚拟化和使用非常大的可伸缩资源来实现的,其中用户通过为服务使用的资源份额付费来访问服务。为了实现高效调度,提出了几种工作流调度技术。其中,最大最小法最为突出,由于其启发式的性质,其特点包括效率和保证最优或接近最优解的能力。文献中已经提出了对其功能的一些增强,并且仍在进行改进工作。本文提出了一种最小化总执行时间的解决方案,其中工作流任务长度总是在适当调度之前考虑。并与标准的Max-Min调度方案进行了比较。该方案优于标准方案;采用两个现实的科学工作流程作为测试数据进行仿真。

In this study, Convolution Neural Network (CNN)-based learning method, which is well-used in deep learning is applied to evaluate optimization algorithms for improved accuracy in cervix cancer detection. The convolutional layer in this study is made up of numerous convolution kernels which are used to compute different feature maps for representations of the inputs. As a result, the architecture of the model consisting of convolutional layers, pooling layers, and fully-connected layers is designed by stacking the network layers. The model is evaluated firstly by increasing the amount of image data through image augmentation. Furthermore, the hyper parameters for optimum performance are chosen. Finally, analysis is performed for Stochastic gradient descent (SGD), Root Mean Square Propagation (RMSprop) and Adaptive Moment Estimation (Adam) optimizers to determine which improves the networks performance for the classification of cervix cancer.
本研究采用深度学习中常用的基于卷积神经网络(CNN)的学习方法对优化算法进行评估,以提高宫颈癌检测的准确率。本研究中的卷积层由许多卷积核组成,这些卷积核用于计算不同的特征映射以表示输入。因此,通过堆叠网络层,设计了由卷积层、池化层和全连接层组成的模型体系结构。首先通过图像增强增加图像数据量来评估模型。此外,还选择了性能最优的超参数。最后,对随机梯度下降(SGD)、均方根传播(RMSprop)和自适应矩估计(Adam)优化器进行了分析,以确定哪种优化器可以提高宫颈癌分类网络的性能。
