A simulated coaxial decomposition chamber was designed and used to simulate the decomposition of SF6 under the effect of fixed metallic artificial defect on the surface of the spacer at the pressure of 0.2MPa when the chamber is energized at a 45KV experimental voltage over the period of 30 hours due to the presence of partial discharge caused by the artificial defect.

While WMNs have self-healing, self-forming and dynamic topology features, they still pose challenges for the implementation of multimedia applications, such as voice, in various scenarios. The research has been conducted using a network simulator and experiments conducted on three main scenarios with mesh nodes in no-mobility, partial mobility and full mobility deployments. The experiments consider the IEEE 802.11n/g/e/s standards; G.711, G.726 and G.729 voice codecs; and AODV-reactive, OLSR-proactive and HWMP hybrid routing protocols. The measurement and evaluation is based on the Mean Opinion Score (MOS) rating-scale defined by ITU-T standard and supported by the delay, jitter and packet loss metrics. The proposed approaches identify the integration choices and inclusion of supportive mesh nodes in order to improve VoIP quality. The analysis of the results show that our proposed approaches improve the VoIP quality in terms of 5 point MOS rating-scale by 0.2 in no mobility, 2.2 in partial mobility and 0.9 in full mobility scenarios. The results show that whereas minor gains are achieved in the no-mobility scenarios, significant and considerable gains are achieved for the full mobility and partial mobility scenarios, respectively. The results for the two latter cases thus illustrate the merit of the proposed approach.","PeriodicalId":6528,"journal":{"name":"2017 International Conference on Electrical Engineering and Computer Science (ICECOS)","volume":"13 1","pages":"22-27"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73916103","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}

Architecture pattern provides the skeleton of a system by defining the components and connector required to establish the requirements of the system. It also encourages reusing the architecture to many similar systems or family of systems. Moreover, architecture pattern addresses the non-functional requirements of the system by reasoning the quality attributes aimed to achieve. Selection of appropriate architecture pattern has a direct impact on the success of the system and also to the quality factors of the system. Tactics, on the other hand, are fine-grained design decisions which complement architecture pattern in achieving a certain quality of the software system. However, selection of architectural solutions for the target software system can be a complex task because of the varying impact factors of architecture solutions for different quality requirements. Because of the notable impact factor on the overall system, architectural solutions should not be chosen without proven facts. The main aim of this research is to find the best possible way to achieve an appropriate set of architectural solutions. Therefore, we propose an approach to achieve a suitable set of architectural solutions based on the target quality goals. The proposed approach uses quality goals to retrieve a candidate set of architecture solutions and finally achieve an appropriate set of final architectural solutions by omitting conflicting solutions through mapping relationship impact among architectural solutions. Through a comprehensive case study, the effectiveness of the proposed approach is found in achieving an appropriate set of architectural solutions with no negative confliction among the final solutions.","PeriodicalId":6528,"journal":{"name":"2017 International Conference on Electrical Engineering and Computer Science (ICECOS)","volume":"15 1","pages":"131-136"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88100728","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 expected spectrum “crunch” requires highly efficient radio resource management schemes with low complexity and high responsiveness to the changing network conditions. Spectrum sharing is regarded as an essential approach to regaining access to otherwise unused spectrum and it is considered an essential component in the development of IoT and 5G networks. Spectrum sharing can be conducted at different time scales. As the time scale of the operation of spectrum sharing decreases, the possibility for utilising more available spectrum holes increases. However, the shorter time scale brings with it challenges. Efficient decisions regarding the use of spectrum sharing require accurate knowledge of the spatial and temporal spectrum use in a geographical area of interest. This knowledge can be represented in Radio Spectrum Maps which need to be generated efficiently and accurately. In this paper we give an overview of the spectrum sharing concept for IoT and 5G networks. We also present our research on spectrum sharing to enable Smart Building IoT applications.","PeriodicalId":6528,"journal":{"name":"2017 International Conference on Electrical Engineering and Computer Science (ICECOS)","volume":"21 1","pages":"7-9"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84541016","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}

CRFs is proposed to cope the limitation of both generative Hidden Markov Models (HMMs) and discriminative Maximum Entropy Markov Models (MEMMs) for solving the sequential classification problems. CRFs is widely used to accomplish the sequential classification which has a temporal dimension. On its way, CRFs has been improved both on the structural learning model as well as on the area of implementation. Those areas are varying from information extraction, image understanding, computer vision, behavioral analysis, natural language processing, bioinformatics, etc. This review provides a compact and informative summary of the major research on CRFs. We present a brief description about CRFs fundamental, CRFs roadmap, and CRFs related area of implementation from several literature papers on CRFs. The contribution of this paper is to explore the roadmap of CRFs research and potential prospect in developing CRFs to solve machine learning problems, particularly problems with sequential structures.","PeriodicalId":6528,"journal":{"name":"2017 International Conference on Electrical Engineering and Computer Science (ICECOS)","volume":"36 1","pages":"143-148"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74842051","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}
