A channel allocation algorithm is introduced to adaptively assign the available channels to the secondary users while taking into considerations their buffer occupancies as well as the maximum available bit budget and the deadlines of the video frames. The proposed scheme aims at improving the video quality by increasing the number of received enhancement layers for each transmitted video frame. This is done by jointly adapting the modulation levels and channel coding while benefiting from frames retransmissions, when possible, to guarantee their successful reception when they can still meet their deadlines. The simulation results show that the proposed scheme reacts to the variations in channel conditions as well the dynamics of the playback buffers at the secondary users’ end by representing the transmitted video information at the highest possible bit rates while exploiting the scalability feature of the encoded video frames. This is reflected in the improved perceptual quality as received by the secondary users with uninterrupted playback.","PeriodicalId":446936,"journal":{"name":"2016 European Modelling Symposium (EMS)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123421947","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}

EV coordinated charging relies on the remarkable development of communication infrastructure in smart grids which enables vehicle-grid communication via proper communication pathways. The proposed architecture is composed of two units, an aggregator unit in addition to an optimization unit. While, the aggregator unit provides data collection and initial processing, the optimization unit optimally coordinates the charging decisions to guarantee service reliability while, minimizing the operating costs, and satisfying the system and customers constraints. Sliding horizon concept is utilized to manage real-time data and to allow plug-and-play option for EV owners. The simulation results do not only demonstrate the robust performance of the proposed approach in tackling the dynamics of different parking lots in a timely manner but demonstrate the effectiveness of which in mitigating the impact of high penetration of EV and PV panels through optimal coordination of the EV as small energy storage units.","PeriodicalId":446936,"journal":{"name":"2016 European Modelling Symposium (EMS)","volume":"139 1-2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128758919","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}

Just a few projects among those put forward for funding can be actually accepted, due to the unavoidable discrepancy between available money and required investments. Though overall profit maximization could appear as the natural allocation goal, it is to be considered that such an allocation may eventually produce a rather unbalanced distribution of the overall budget, where some departments get most of it and others get a very small slice or no money at all. In this paper, we examine how the search for fairness in budget allocation impacts the overall profit, to assess whether a greater degree of satisfaction among departments can be achieved while pursuing profit maximization at the same time. We adopt a constrained knapsack model and the Herfindahl-Hirschman Index (HHI) as a measure of fairness, and perform a MonteCarlo simulation to measure the extent of profit sacrifice in the quest for fairness. We find that just a small sacrifice in profit is often needed to achieve a balanced distribution of the overall budget.","PeriodicalId":446936,"journal":{"name":"2016 European Modelling Symposium (EMS)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128090311","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}

Such intelligent windows provide additional possibilities for observing the machine interior under difficult visibility conditions, combine and reduce the number of supporting systems and enrich the machine interior with contextual information. For creating a view-dependent virtual and augmented reality individual solution approaches presented in other research were combined, extended and applied to machine tools to form an intelligent window. For the impression of a real window and perspectively correctly overlay virtual objects, the operator’s head position is tracked and the perspective projection matrix is calculated continuously. The necessary equations are presented. In an experimental setup, view-dependent rendering for virtual reality on opaque displays as well as augmented reality on transparent displays were validated. The rendering is performing well and an accurate overlay of virtual and real machine interior can be created. However, several difficulties regarding illumination, transparency and human stereo vision did occur. Possible improvements and solutions are suggested.","PeriodicalId":446936,"journal":{"name":"2016 European Modelling Symposium (EMS)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134244483","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}
