Designing a reliable communication system requires knowledge of the transmission parameters of the channel. There is a need for the development of adaptive signaling schemes that would dynamically optimize the signal parameters of the physical layer of communication protocols. Wireless channels are often assumed to be wide sense stationary (WSS) with uncorrelated scattering (US). The WSSUS assumption allows for simultaneous modeling of time dispersion leading to the frequency selectivity of the channel, and time variability resulting in frequency dispersion. However, in the case of many underwater communication channels, especially when system terminals are in movement, the channel can be modeled as WSSUS only in restricted periods of time, and in limited frequency ranges. The paper presents a method for determining the time interval, wherein the WSS assumption is fulfilled, on the basis of a complex envelope of the received bandpass signal.","PeriodicalId":314687,"journal":{"name":"2017 IEEE International Conference on INnovations in Intelligent SysTems and Applications (INISTA)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130230218","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}

Although, several algorithms have been proposed for this task, they remain computationally expensive. To resolve this issue, this paper presents an efficient method called DITP-Miner to mine ITPs. In our proposed algorithm, there are four phases. First, we scan the database once to find frequent 1-patterns with their tidsets. Second, we generate inter-transaction 1-pattern candidates with the given span values and sort all the frequent 1-patterns in an ascending order according to their supports. Third, based on frequent items found in phases 1 and 2, we find frequent 2-patterns with their diffsets. In the fourth phase, we use diffsets and DFS (Depth-First-Search) technique to get all frequent ITPs. In addition, three propositions are also offered to early prune infrequent patterns in the processing. Proposition 1 is used to early prune infrequent inter-transaction 1-pattrens, Proposition 2 is used to quickly compute the support of patterns, and Proposition 3 (subsume concept) is used to quickly compute the support of patterns and to early prune infrequent patterns, which reduce the search space. Through experimental results, we find out our proposed approach is more efficient than ITP-miner in both the mining time and the memory usage.","PeriodicalId":314687,"journal":{"name":"2017 IEEE International Conference on INnovations in Intelligent SysTems and Applications (INISTA)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134353965","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}

Because the living human body is at a certain temperature, each thermal target point implies possible victim. Robots produced for search and rescue are expected to be able to perceive and steer toward the thermal targets. The focus of this work, which is also a criterion of RoboCup competitions, is the development of an exploration method for the determination of thermal targets. An algorithm has been developed which relies on giving travel priority to the thermal information emitting targets in the environment. So that the victims can be detected more effectively. Additional methodsg, such as human detection from image processing, detecting carbon dioxide gas, motion detection, etc., can be used to identify the victim, in consideration of the fact that every thermal target in the environment may not be human bein This study only involves detecting thermal targets and directing the mobile robots to them. Successful results are ensured by making the method more stable thanks to tests in both the real environment and the simulation environment. Gazebo is used as the simulation environment, and a differential drive mobile robot with a thermal camera is used for real environment experiments. Since there is no thermal camera in Gazebo simulation environment, a system was designed to represent thermal targets. This system is based on obtaining representative thermal images by applying various filters to normal camera images.","PeriodicalId":314687,"journal":{"name":"2017 IEEE International Conference on INnovations in Intelligent SysTems and Applications (INISTA)","volume":"3 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126025931","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}
