The main issues in this area are the reconstruction process or obtaining the entire original message out of the DSS and the repair process or recovering the lost stored data of a failed node. The product matrix regenerating codes as class of codes in such networks offer an optimal tradeoff between the repair bandwidth and the data amount stored per node. In our paper, we are proposing a new code, a shortened MSR code, that gives new bound of the wanted tradeoff. The shortened MSR code is constructed by introducing modification on the mother code, product matrix MSR code. By comparing both constructions we prove that our code gives better performances regarding the repair bandwidth and the number of connected nodes needed for the repair and the reconstruction processes, while maintaining the storage per node unchanged. The comparison is extended between the new shortened MSR code and a new product matrix MSR code designed according to the parameter values obtained from our new code. The necessity of this is having a fair and convincing comparison results, which shows again that our code has some improvements in the overall distributed system.","PeriodicalId":174688,"journal":{"name":"2016 8th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128963680","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}

Integrity refers to the property that the closed-loop system remains stable against arbitrary failures of certain subsystems in order to increase the reliability of industrial systems. The proposed approach is based on the Lyapunov equation stability mapping technique. Instead of solving 2n equations to determine the boundaries of the stabilizing regions that is required in the standard Lyapunov approach, it is necessary and sufficient to solve at most two equations with respect to the controller parameters in the proposed approach. Using this approach, an algorithm is asserted to determine non-conservative controller gain regions that guarantee the stability of the multivariable systems when any one of the controller parameters fails to operate. Lastly, two benchmark case studies are included within the scope of this study to verify the effectiveness and correctness of the derived theoretical results.","PeriodicalId":174688,"journal":{"name":"2016 8th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131381596","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}

Most of those requirements are created by their unique usage - these devices are in user proximity, mostly directly on a human body. This brings also a lot of complications for researchers and engineers. They must consider i.e. safety terms or small dimensions, which are interfering with requirements such as battery life and computational power. This paper presents a study of computational power versus power efficiency of modern System on a Chip (SoC) platform for Internet of Things (IoT). Target of this study is to determine which currently accessible SoC on the market is most suitable for usage in wearables and emerging applications like e.g. augmented reality.

These codes are especially important for efficient repair of a failed node in a minimum storage regenerating (MSR) codes. Moreover, they achieve perfect security against the eavesdropper attacks, i.e., the observer can not reveal the whole message. Here the aim is information protection of individual files and small groups from the entire message, when the attacker has access to a limited number of storage nodes. This paper considers improving the perfect security in such DSS. The enhanced secrecy is presented by performing explicit code construction by using an outer and an inner code. The proposed construction code model includes coset code as an outer code or pre-coding step that ensures the security of the system and an MSR interference alignment code as an inner one that performs an efficient reconstruction and repair process. Using this construction we show that the eavesdropper can not reveal the message, and, that he can not access any subset of individual information from the original message, without any significant loss in the storage capacity.","PeriodicalId":174688,"journal":{"name":"2016 8th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT)","volume":"1 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133080565","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}

Using the transfer functions apparatus in a structural representation of these systems yields systems in the form of a sequence of similar first order aperiodic blocks. The transient response of the system is characterized by the absence of overshoot. The situation changes considerably if the control system with a binomial distribution of eigenvalues is in a nonzero initial state. The system in the form of the sequence of similar first order aperiodic blocks mathematically turns out to be a three-parameter system with the following parameters: the absolute value of the negative real number, its multiplicity which is equal to the order of the system and the transfer coefficient. It was determined that in the three-parameter system, which is a present work research object, peaks of the state vector norm in the free motion trajectories may occur for any values of the absolute value of the negative eigenvalue.","PeriodicalId":174688,"journal":{"name":"2016 8th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121880616","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}
