It looks like a serious game in which the player builds a world of concrete, paths and grass. We show in this paper that the inner model of AlgoPath is based on the Model-View-Controller architecture (MVC). We intend to add a virtual teacher in this architecture, who oversees the players' interactions and intervenes when the interactions do not correspond to what is expected by a real teacher. We explain how the model of the virtual teacher interacts with the Controller component of the architecture. We describe the model that lets a real teacher add his particular comments for the various mistakes that can be made by a player. We explore the solutions to implement two multiplayer gameplay types: a competitive one, in which two or several players fight against one another to be the first to find the best algorithm, and a collaborative one, in which they have to find the best algorithm as a team. Finally, we explain our choice to develop the distributed version of AlgoPath with Unity.","PeriodicalId":226884,"journal":{"name":"2014 14th International Conference on Innovations for Community Services (I4CS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126078629","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}

We concentrate on the convergence of optical and wireless networks for the deployment of Internet access networks so that we can exploit the opportunities of both technologies. We focus on network dimensioning and placement of equipment in hybrid optical-wireless access networks. A number of integrated optical-wireless architectures have been investigated for the greenfield deployment of future access networks. A novel hybrid network infrastructure, namely PON-LTE-WiFi, has been proposed where fiber will be deployed as deeply as affordable/practical and then, wireless systems will be used to extend this connectivity to a large number of locations and ultimately connect the wireless end users. We propose a 3-phase network design optimization scheme for greenfield deployment of PON-LTE-WiFi access network infrastructure. Finally, we propose an ILP model which optimizes the greenfield deployment of LTE network based on the static distribution of mobile user equipment (MUE). The proposed model takes into account various physical layer constraints of LTE network and determines the optimal clustering of MUEs as well as the location of eNBs in a neighborhood. Computational experiments have been conducted on three different data sets consisting of 128, 256 and 512 mobile user equipment in order to evaluate the performance of the proposed scheme.","PeriodicalId":226884,"journal":{"name":"2014 14th International Conference on Innovations for Community Services (I4CS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133122289","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}

Unpacking his library, Walter Benjamin describes how a collection is singular [2]. Collections are not unified wholes, but rather chains of undefined objects. Classify, search, arrange or browse collections are personal processes influenced by internal reflexions. Working on figural and non-figural collections, Piaget and Inhelder explain how space and time influence the way a collector looks to his collection [13]. As a result, representing collections is an issue for computer scientists. Here, we propose a time-based method, which consideres chronological events and draws a time-weighted graph defining patterns of items. We therefore show how this graph outputs different results depending on when it is requested. This work is based on an architecture, designed by Openrendezvous.com, a collaborative web-based application helping to make appointments. Our goal is to adapt a social graph used to define the perfect moment for two people to meet, to the collection case. We discuss how we can build a structure that helps to compute the ideal moment for an item to meet a collector.","PeriodicalId":226884,"journal":{"name":"2014 14th International Conference on Innovations for Community Services (I4CS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125430744","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}

We also propose a general privacy enhancing cloud audit concept which, we do present based on a recently proposed framework. This framework introduces the use of audit agents for collecting digital evidence from different sources in cloud environments. Obviously, the elicitation and storage of such evidence leads to new privacy concerns of cloud customers, since it may reveal sensitive information about the utilization of cloud services. We remedy this by applying Somewhat Homomorphic Encryption (SHE) and Public-Key Searchable Encryption (PEKS) to the collection of digital evidence. By considering prominent audit event use cases we show that the amount of cleartext information provided to an evidence storing entity and subsequently to a third-party auditor can be shaped in a good balance taking into account both, i) the customers' privacy and ii) the fact that stored information may need to have probative value. We believe that the administrative domain responsible for an evidence storing database falls under the adversary model \"honest-but-curious\" and thus should perform query responses from the auditor with respect to a given cloud audit use case by purely performing operations on encrypted digital evidence data.","PeriodicalId":226884,"journal":{"name":"2014 14th International Conference on Innovations for Community Services (I4CS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130352970","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}
