Given the power dependency of Information Communication Technology (ICT), the unreliable power supply which upon the ICTD infrastructure currently runs on is set to provide challenges if not addressed. Over the years, various ICT infrastructure installed in the SLL has been destroyed and communication compromised due to power outages. With problems of some parts of South Africa being off-grid, poorly supplied and serviced due to their geography, or under load-shedding, there is need to exploit other energy sources. This power problem has coincided with the advent of renewable and clean energy and environmentally aware computing and engineering. Such a coincident pushes for the research in optimizing locally available renewable energy sources such as wind and solar which when combined form Hybrid Energy Systems (HES). HES have been widely used as of late but still lack the financial and environmental constraint optimization capability to achieve their maximum potential. This paper therefore proposes Genetic Algorithms (GA) applied to HES for the optimal utilization and mix of the power sources for both economic and environmental dispatch to suit the low cost and minimal adverse health issues in rural South Africa.","PeriodicalId":380601,"journal":{"name":"2014 IEEE 6th International Conference on Adaptive Science & Technology (ICAST)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116763764","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}

However, education in Africa and specifically Nigeria still faces a 21st Century challenge in making education available and accessible to all. As a means of responding adequately to this huge unmet demand for education in Nigeria, this paper proposes a Synchronous Learning System which could be used in Nigerian Universities as a way of alleviating challenges like overcrowded classrooms and lack of adequate human resources. It presents a functional framework to exemplify services which could be offered in the proposed virtual learning system to depict the peculiarity of an instructor-led classroom within the Nigerian academic context, an operational design which describes how a custom e-learning portal could be integrated with an Open source Video Conference server to facilitate learning in virtual classrooms. Furthermore, it proposes a virtual Learning Network architecture to show how both onsite and remote students could optimize quality network access in realizing these electronic learning services.","PeriodicalId":380601,"journal":{"name":"2014 IEEE 6th International Conference on Adaptive Science & Technology (ICAST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127444157","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}

The MVDR supported by joint approximate diagonalization of eigenmatrices (JADE) algorithm is used to estimate the direction of arrivals of coherent signals in non-coherent groups. The generalized steering vectors using JADE algorithm are first estimated, and then the spectrum methods are realized to estimate the DOA of each signal. Root mean square error (RMSE) values are computed in different scenarios for the proposed method as well as JADE-MUSIC and the corresponding results are compared. Although both methods resolved the signals correctly, simulation results show that JADE based MVDR has better performances in the cases of low number of antenna elements and snapshots. The DOAs obtained are then processed using LMS adaptive beamforming algorithm to steer the main lobe of the radiation pattern to desired angles (signals) and the nulls to undesired angles (signals). The simulation results also reveal that adaptive beamforming is successfully done by annihilating the effects of undesired signals significantly.","PeriodicalId":380601,"journal":{"name":"2014 IEEE 6th International Conference on Adaptive Science & Technology (ICAST)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126167763","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}
