Multiple input multiple output (MIMO) systems, which are suitable for mmWave communications, facilitate building large arrays of communication channel with Reasonable form factors indoor and outdoor communications. In both, indoors and outdoors communications a reasonable coverage can be achieved by the high gains of array. Deploying MIMO systems in frequency-division duplex mode faces the issue of high feedback overhead of channel state information (CSI) to the transmitter. This issue is attributed to the used multiplexing algorithm. From other hand, it is expected that by 2020, all new 5G technologies will be in operation. Hence, it is crucial to investigate and analyze using the MIMO system with orthogonal frequency-division multiplexing OFDM modulation in 5G technology. This research sheds light on the potential challenges of implementing MIMOOFDM in 5G technology. It proposed four models with different number of transmitter and receiver antenna elements in the array. All proposed model used 2 elements per row in transmitter and receiver antenna. The four models are implemented in two cases Line of sight LOS and Non Line of Sight NLOS. The channel rank and condition number of channel matrix are regarded as significant and accurate mathematical indicators which can be used to evaluation MIMO channel technology. The condition number is calculated from the obtained results of four models with rank of channel metrics.
多输入多输出(MIMO)系统适用于毫米波通信,便于构建具有合理外形因素的大型通信信道阵列,用于室内和室外通信。在室内和室外通信中,阵列的高增益都可以实现合理的覆盖。在分频双工模式下部署MIMO系统面临着信道状态信息(CSI)对发射机的高反馈开销问题。此问题归因于使用的多路复用算法。另一方面,预计到2020年,所有新的5G技术都将投入使用。因此,研究和分析在5G技术中使用正交频分复用OFDM调制的MIMO系统是至关重要的。这项研究揭示了在5G技术中实现MIMOOFDM的潜在挑战。提出了阵列中不同数量的收发天线单元的四种模型。所提出的模型均采用每行2个单元的发射天线和接收天线。这四种模型分别在瞄准线LOS和非瞄准线LOS两种情况下实现。信道秩和信道矩阵条件数是评价MIMO信道技术的重要而准确的数学指标。根据四种信道度量等级模型得到的结果计算条件数。

Extending classroom contact hours is a primordial concern at the Higher College of Technology, Muscat, Sultanate of Oman in particular. One of the tangible ways to address this concern is to assess the extent of available academic and technology-related resources, ascertain the utilization and initiate a pedagogy that has yet to be done in the institution — a hybrid course. This paper examines the student's learning and engagement in an aggressive move in deploying a didactic and highly structured online course in Basic Mathematics. The course was delivered for two full semesters involving eight hundred ninety five foundation and diploma first year level students. The results showed significant increase in student's engagement before, during and after classroom contact hours. This increment however did not significantly translate to a growth in student learning as measured by their final course mark. Furthermore, this paper demonstrates that the ingenuity to facilitate learning and student engagement in an online platform that creates a promising solution in diminishing human capital resources and lessening fund allocation in public govern colleges. The implications of this study are important for all the stakeholders primarily for the college administration in delivering a technology-enabled learning environment and secondarily, for the government to bridge the gap between economy-triggered incapacities all for the noble aim of educating the citizens to the highest and globally accepted standards.
延长课堂接触时间是阿曼苏丹国马斯喀特高等技术学院最关心的问题。解决这一问题的具体方法之一是评估现有的学术和技术资源的程度,确定其利用情况,并开始一种尚未在该机构实施的教学方法- -一种混合课程。本文考察了学生的学习和参与在一个积极的举动部署教学和高度结构化的在线课程基础数学。该课程为期两个学期,涉及895名基础和文凭一年级的学生。结果显示,在课堂接触时间之前、期间和之后,学生的参与度显著提高。然而,这种增长并没有显著转化为学生学习成绩的增长,这是通过他们的最终课程成绩来衡量的。此外,本文还证明了在一个在线平台上促进学习和学生参与的独创性,为减少公共治理大学的人力资本资源和减少资金分配创造了一个有希望的解决方案。本研究的意义对所有利益相关者都很重要,首先是大学管理部门提供一个技术支持的学习环境,其次是政府弥合经济引发的能力差距,所有这些都是为了将公民教育到最高和全球公认的标准。

In recent years, Sultanate of Oman has formed an innovative approaches and initiatives to promote entrepreneurship education at national level. Many of the private and public sectors take this initiative through research, curriculum development, educators' trainings, and collaboration with non-governmental organization (NGOs). Various pilot projects were implemented in order to promote entrepreneurship education among youth, university students, graduates and unemployed citizens. The government encourages its citizens to participate equally in this initiative to further help the progress of economic development in the country. In academic level, the role of Oman's higher education institutions is to undergo a fundamental change in order to encourage, support, and educate young entrepreneurs and technopreneurs of the future. These approaches are all aligned to the Sultanate's Vision Oman 2020 Economic Development Plan. The main purpose of this study is to propose a concept and model to strengthen the implementation of technopreneurship in higher education institutions in the Sultanate of Oman that are beyond the traditional domain of interdisciplinary technology. In addition, the model will serve as the role player of each university's centre to spread out relevant information about technopreneur development and commercializing technology between higher education institutions and the industry.

With the rising global energy issues regarding sustainability, environmental degradation and fossil fuel exhaustion, several countries are now focusing on finding alternative sustainable solutions. At the current state, there are no clear alternatives other than renewable energy sources which have recently led to the increase of entrepreneurial businesses primarily dealing with the advancement and uptake of renewable energy technologies. However, being an under-researched area, there is no clarity on the skills associated with the business models of the renewable energy sector. What are the current trends in terms of the interpersonal, professional and core technical skills that employers are actively seeking in this sector? How will nascent entrepreneurs address the skills gap or subject specific knowledge challenges? Using content analysis, this study reviews online job advertisements to shed some light on the skills distribution in management and technical-oriented roles in the renewable job sector. The study found management-oriented roles to have a more widespread skills parameter in the personal skills category as compared to technical-oriented roles. The professional and technical skills distribution shows technical-oriented jobs seeking a higher rate of subject-specific skills or knowledge than management-oriented roles. The study also found a lack of choices for undergraduate degrees on renewable energy when compared with postgraduate degree choices in the UK. This raises several questions like whether such gaps in subject choices at universities are limiting the entrepreneurial prospects among students. Are these factors fuelling the technical skills deficit currently witnessed in the renewable energy job sector? Perhaps, there is a need for universities to revisit their business and programme design models to investigate whether the undergraduate programmes are being too generic for the 21st century entrepreneurial market?
随着可持续性、环境退化和化石燃料枯竭等全球能源问题的日益严重,一些国家正在集中精力寻找替代的可持续解决办法。在目前的状态下,除了可再生能源之外,没有其他明确的替代品,这最近导致了主要涉及可再生能源技术进步和吸收的创业企业的增加。然而,作为一个研究不足的领域,与可再生能源行业商业模式相关的技能并不明确。在人际交往能力、专业技能和核心技术技能方面,雇主在这一领域积极寻求的趋势是什么?初出茅庐的企业家将如何解决技能差距或特定学科的知识挑战?通过内容分析,本研究回顾了在线招聘广告,以揭示可再生就业领域中管理和技术导向型角色的技能分布。研究发现,与技术型角色相比,管理型角色在个人技能类别中具有更广泛的技能参数。专业和技术技能分布表明,技术导向的工作比管理导向的工作更需要特定学科的技能或知识。该研究还发现,与英国的研究生学位相比,可再生能源本科学位的选择较少。这引发了几个问题,比如大学在学科选择上的差距是否限制了学生创业的前景。这些因素是否助长了可再生能源行业目前出现的技术技能短缺?或许,大学有必要重新审视它们的商业和课程设计模式,以调查本科课程对21世纪的创业市场来说是否过于通用?

This research investigates the performance of Self-Organizing Map (SOM) Clustering Method to analyze students' e-learning activities with the aim to identify clusters of students who use the e-learning environment in similar ways using data obtained from the log files of their actions as input. The SOM clustering technique was used to group the students into three clusters. Learning behaviors of students in each cluster were analyzed; a relationship between students' learning behaviour and their academic performance (Final Results) was investigated. The analysis shows that students in Cluster1, having the highest interactions frequency with the e-learning, also got the highest final score mean of 91.12%, this followed by Students in Cluster2 with less number of interactions than Cluster1 and final score mean of 75.65%. Finally, students in Cluster3 have least number of interactions than the remaining clusters with least final score mean of 36.57%. The research shows that, students who participate more in Forum activities perform higher, while students with lowest records in Forum activities have the lowest performance. The research found that Forum activity has significant factor on student's course success but it is optional to students and no marks allocated to it. The research suggests that marks should be allocated to Forum activities to encourage students' participations.
本研究调查了自组织地图(SOM)聚类方法的性能,以分析学生的电子学习活动,目的是使用从他们的行为日志文件中获得的数据作为输入,以相似的方式识别使用电子学习环境的学生群。采用SOM聚类技术将学生分为三组。分析各组学生的学习行为;研究了学生的学习行为与学业成绩(最终成绩)之间的关系。分析表明,Cluster1的学生与e-learning互动频率最高,最终得分均值也最高,为91.12%;其次是Cluster2,互动次数少于Cluster1,最终得分均值为75.65%。最后,Cluster3学生的互动次数最少,其最终得分平均值最低,为36.57%。研究表明,参加论坛活动次数越多的学生表现越好,而参加论坛活动次数最少的学生表现最差。研究发现,论坛活动对学生的课程成功有显著的影响,但它是学生可选择的,不计分。研究建议,应该给论坛活动打分,以鼓励学生参与。

Data clustering is a process that partitions the data and groups them together in groups based on their similarities and the dissimilarities existing between the data points. The concept to improve the clustering performance and to manage the imprecise and unbalanced data, this paper proposes a Multi-Objective-based Adaptive Dynamic Directive Operative Fractional Lion algorithm (MO-ADDOFL). The fitness is based on the inter-cluster distance, intra-cluster distance, and the cluster density. The fitness proposed newly in this paper enhances the quality of the clusters and improves the classification accuracy. The MO-ADDOFL operates with the maximum fitness measure and determines the optimal centroid for clustering the data points to form the optimal clusters. The proposed algorithm inherits the advantages of the fractional theory. The experimentation is performed using two benchmark datasets, such as lung cancer and Pima Indians Diabetes dataset, which proves that the classification accuracy of the proposed method is better compared with other clustering algorithms. The maximum classification accuracy of MO-ADDOFL is found as 0.84, for the Pima Indians Diabetes dataset.
数据聚类是对数据进行划分,并根据数据点之间的相似性和差异性将数据分组的过程。为了提高聚类性能和管理不精确和不平衡的数据,本文提出了一种基于多目标的自适应动态指令操作分数狮子算法(MO-ADDOFL)。适应度基于簇间距离、簇内距离和簇密度。本文新提出的适应度提高了聚类的质量,提高了分类精度。MO-ADDOFL以最大适应度度量进行操作,确定数据点聚类的最优质心,形成最优聚类。该算法继承了分数阶理论的优点。使用肺癌和皮马印第安人糖尿病两个基准数据集进行了实验,实验结果表明,与其他聚类算法相比,本文方法的分类准确率更高。对于皮马印第安人糖尿病数据集,MO-ADDOFL的最大分类准确率为0.84。

Cross border infiltration or surpassing is an illegal attempt of crossing the international border to carry out abnormal activities. Many threats such as terrorist is one of the major issue in international community. Every country wants their nation to be free from all types of threats and can maintain the harmony of the nation. To protect from these type of cross border activity, Inclusive Border Management System (IBMS) is proposed which is expected to decrease the penetration at borders of nations. It is a coordination of labor, sensor, computer networks, insight and control arrangements. It incorporates Electro Optic Sensors (high determination day and night camera) radars and the preferences. This work is expected to make a reference library on threat signature utilizing intellectual innovation which will upgrade the knowledge for IBMS. The goal of this work is to reduce the miss rate radically by perusing the administrators brainwave examples and utilizing them to decide whether it has been identified a conceivable threat without monitoring it. This cap system proposes to utilize an Electroencephalogram (EEG) cap to capture the observer brain signals and afterward records when the observer identifies a threat. The combination of algorithm and EEG brain waves not just reduces false alerts, it additionally causes spectators to distinguish indications of threats that would be disregarded, for example, flying feathered creatures, influencing branches or non threat protest agreeing the activity recognition. This examination means to recommend a superior streamlining method on P300 signals and build an operational library of threat signature.
越境渗透或超越是企图越过国际边界进行异常活动的非法行为。恐怖主义等许多威胁是国际社会面临的主要问题之一。每个国家都希望自己的国家免受各种威胁,并能保持国家的和谐。为了防止这些类型的跨境活动,提出了包容性边境管理系统(IBMS),预计将减少国家边境的渗透。它是劳动力、传感器、计算机网络、洞察力和控制安排的协调。它结合了光电传感器(高分辨力的白天和夜间相机)、雷达和偏好。本研究可望建立一个利用知识创新的威胁签名参考库,提升IBMS的知识水平。这项工作的目标是通过仔细阅读管理员的脑波示例,并利用它们来确定是否已识别出可想象的威胁而不进行监视,从而从根本上降低漏检率。该帽子系统提出利用脑电图(EEG)帽来捕获观察者的大脑信号,并在观察者识别威胁时进行记录。算法与脑电图脑电波的结合不仅减少了错误警报,还使观众区分出可能被忽视的威胁迹象,例如飞行的羽毛生物,影响树枝或非威胁抗议,同意活动识别。本研究旨在推荐一种更好的P300信号精简方法,并建立一个可操作的威胁签名库。

Knowledge Management is been known as the most strategic asset of organizations over the period of time. Since 1990s it has been used as a lifeline and tool to achieve superior performance. Business Intelligence task is also to provide the right information, to the right person at the right format and time to support better decision making process. Both types of information management technologies are now widely used for organizational performance improvement tools. However, the implementation and practices of a complete Knowledge Management System and Business Intelligence practices in organizations are still debatable and needs more research. Comprehensive discussion on theory, research and practices are required to gain the business insights. This review paper is written to provide an overview to the executives and scholars with pragmatic understanding about integrating knowledge management and business Intelligence practices and technologies for successful performance. It also discusses that how critical knowledge for organizations that must depend on information and communication technologies for strategic planning, dynamic learning, problem solving and better decision making process.
在过去的一段时间里,知识管理被认为是组织最具战略性的资产。自20世纪90年代以来,它已被用作实现卓越性能的生命线和工具。商业智能的任务也是在正确的格式和时间向正确的人提供正确的信息,以支持更好的决策制定过程。这两种类型的信息管理技术现在被广泛用于组织绩效改进工具。然而,一个完整的知识管理系统和商业智能实践在组织中的实施和实践仍然存在争议,需要更多的研究。需要对理论、研究和实践进行全面的讨论,以获得商业见解。这篇评论文章的目的是为管理人员和学者提供一个概述,以实用的方式理解如何将知识管理和商业智能实践和技术集成到成功的绩效中。它还讨论了如何关键知识的组织必须依赖于信息和通信技术的战略规划,动态学习,解决问题和更好的决策过程。
