Before the data are stored in the cache, they have to be transferred from a server through the mobile network. The mobile network is prone to failure caused by users' movement. Moreover, the speed of the network is variable because of various telecommunications technologies. Using cellular network for the communication is also expensive. Thus, once the data are downloaded, they should be stored in the cache for future reuse. On the other hand, the cached data may be in inconsistent state if the original data are changed on the server side. In this paper, we present an adaptive method for maintaining cache consistency which saves network traffic by reducing the number of messages needed for inconsistency detection.","PeriodicalId":314029,"journal":{"name":"2013 3rd Eastern European Regional Conference on the Engineering of Computer Based Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122955418","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}

Layer Based Approach of Corner Detection and Classification in Quantized Range Images 基于层的量化距离图像角点检测与分类方法

Having significantly lower range resolution than spatial introduces challenges in spatial information understanding. The method consists of processing the layers individually. Each layer is treated as binary images and morphologic operations are applied to extract iso-depth lines. Based on these lines we detect and classify corners using a set of conditions. We present results of the algorithm based on synthetic images generated from different viewpoints of a scene.","PeriodicalId":314029,"journal":{"name":"2013 3rd Eastern European Regional Conference on the Engineering of Computer Based Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134250561","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}

Ekler","doi":"10.1109/ECBS-EERC.2013.23","DOIUrl":"https://doi.org/10.1109/ECBS-EERC.2013.23","url":null,"abstract":"Nowadays BitTorrent is a popular peer-to-peer file sharing protocol. Thanks to the advancement and prevalence of smart phones the usage of the protocol is increasing, since mobile devices are capable of joining BitTorrent swarms as well. The key of the protocol is to distribute content between peers therefore it is very important that peers have reliable network connections and provide the correct content. In this paper we analyze the reliability of BitTorrent protocol in mobile environment by observing the availability rate of peers and the poisoning phenomenon in the system. For this research we have collected anonymous statistics retrieved by clients using DrTorrent. DrTorrent is a BitTorrent client that we have implemented on the Android platform. It was published on Google Play Store almost half a year ago and we have collected many experiences since then. In this research we introduce statistics and real measurements about DrTorrent and highlight the key points and relationships. This work can be considered as a pioneer work in the field of modern smart phone peer-to-peer research.","PeriodicalId":314029,"journal":{"name":"2013 3rd Eastern European Regional Conference on the Engineering of Computer Based Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116057419","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}

Cetic","doi":"10.1109/ECBS-EERC.2013.15","DOIUrl":"https://doi.org/10.1109/ECBS-EERC.2013.15","url":null,"abstract":"With the expansion of the market of available embedded platforms the variety of target architectures is rapidly increasing. Therefore the need for retarget able software development tools has never been greater. The C compiler, probably the most significant development tool for embedded systems, is required to be quickly and easily adaptable for new architectures. This paper describes one such generic C compiler which has been adapted for Crystal 32-bit and MIPS 32-bit as two different target platforms. The aim of this paper is to prove that the compiler has modifiable infrastructure and can be easily adapted to support new architectures, as well as to improve the compiler in terms of extending this capability. The compiler has been tested for correctness for both architectures. For Crystal 32-bit platform quality testing has also been performed and all test results showed remarkable results. On the other hand, for MIPS 32-bit architecture, for which full compiler support is still an ongoing process, correctness tests were performed with exceptions of C language aspects which are not commonly used in embedded system applications. The analyses of these tests showed convincing results for embedded domain and promising results for reaching full MIPS 32-bit support.","PeriodicalId":314029,"journal":{"name":"2013 3rd Eastern European Regional Conference on the Engineering of Computer Based Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116735557","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}
