However, the fact that nodes exchange information simultaneously (Transmission and reception activities) in a bi-directional manner on each of the k considered links; comes with considerable potential gain in terms of channel capacity. On the other hand, halfduplex communication between the k MIMO links comes with the advantage that it does not suffer from self interference. Half duplex MIMO communication however comes with the drawback that it only achieves single link channel capacity. It also can still result in inter-user interference. This paper proposes a mixed strategy which takes advantage of the Full-duplex MIMO capacity gain while reducing self-interference by tapping into the Half-duplex potential and also reducing inter-user interference by interleaving Full-duplex and Half-duplex communications on the k MIMO links. This is done by designing optimum transmitter and receive filters for Weighted Sum Rate (WSR) maximisation using the Rosen's gradient projection method. After proper modeling and MATLAB simulation, the obtained results show that the Full-Half duplex Mixed strategy enhances the overall channel capacity as compared to the k-link MIMO Full-duplex WSR maximisation approach.","PeriodicalId":300052,"journal":{"name":"2015 International Conference on Computing, Communication and Security (ICCCS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115653371","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}

Designing appropriate instructional strategies with the best visual experiences enable learners to grasp the complex principle behind the concept and stimulate their interest. Hence, technology can be seen as a panacea. In this regard, a study was conducted to explore Form II learners' view on learning Climate Change with blended learning approach. The theoretical context of this research is underpinned by socio-constructivism. As methodology, an action research was carried out by implementing an interactive educational software, designed based on learners' requirements. A questionnaire was administered to 30 mixed ability learners from a gender-mixed private secondary school with the aim of collecting their learning experience. An active participation of the learners during the face-to-face session demonstrated that through blended learning, they had a clearer understanding and they appreciated the concept with a larger improvement in learners performance. Hence, this active and constructive learning strategy encouraged collaboration and cooperation, and celebrated the autonomy of the learners. Moreover, learners were motivated to take action and address problems in the community, developing their civic responsibility for sustainable development.","PeriodicalId":300052,"journal":{"name":"2015 International Conference on Computing, Communication and Security (ICCCS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117090829","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}

Users present in the vicinity can interact with each other using the embedded technologies in their mobile devices such as GPS, Wi-Fi and Bluetooth. Due to its growing momentum, this new social networking has also aroused the interest of business people and advertisers. However, due to a lack of security in these networks, several privacy concerns were reported. Users are more reluctant to share their locations and to address this issue, some initial solutions to preserve location privacy were implemented. The aim of this paper is to present a clear categorization of the different privacy threats in PMSN. Moreover, the location privacy enforcement policies and techniques used to ensure privacy are outlined and some solutions employed in existent systems are presented and discussed. To the best of our knowledge, this is the first study done outlining several categories of PMSN privacy challenges and their solutions in this new type of social networking services. Finally, some privacy research challenges and future perspectives are proposed.","PeriodicalId":300052,"journal":{"name":"2015 International Conference on Computing, Communication and Security (ICCCS)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124220216","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}

Rough set theory has been regarded as a powerful feasible and effective methodology in the performance of data mining and knowledge discovery activities. This paper introduce a method for building knowledge for the rate of heat transfer (Local Nusselt Number) considering the free convection flow over a vertical flat plate in a fluid-saturated porous medium in the presence of heat sources or sinks and with nonlinear density temperature variation. First, Solutions for a class of coupled nonlinear equations are obtained by using the fourth-order Runge-Kutta method with shooting technique; second, Numerical calculations of rate of heat transfer for different parameters such as; variable suction/blowing, variable wall temperature exponent, heat source/sink, nonlinear density temperature variation (NTD) for both uniform and variable permeability cases are made and presented in tabular form (decision table). Finally, a set of maximally generalized decision rules is generated by using rough sets methodology. The effectiveness of the obtained results will be illustrated by comparing it with previously published work and are found to be in excellent agreement. The proposed method effectively decreases the time and complexity of process to obtaining the rate of heat transfer.","PeriodicalId":300052,"journal":{"name":"2015 International Conference on Computing, Communication and Security (ICCCS)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131511915","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}

So sales and budget sales are considered as important parameters influencing all other decision variables in an organization. Therefore, poor sales forecasting can lead to great losses in an organization caused by inaccurate and non-comprehensive production and human resource planning. Hence, in this research a coherent solution has been proposed for forecasting sales besides refining and revising it continuously by ANFIS1 model with consideration of time series relations. Data has been collected from the public and accessible annual financial reports related to a famous Iranian company. Moreover, for more accuracy in forecasting, the solution has been examined by BPN2 and PSO3 as optimization methods. The comparison between taken prediction and the real data shows that PSO method can optimize some parts of prediction in contrast to the rest which is more coincident to the output of BPN analysis. As a consequence, a hybrid integrated system including both has been designed. This system uses them depending on their abilities to optimize each part, so it can produce more precise results relatively.","PeriodicalId":300052,"journal":{"name":"2015 International Conference on Computing, Communication and Security (ICCCS)","volume":"16 14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126165478","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}
