The main issue of similarity search in time series databases is to improve the search performance since time sequences are usually of high dimension. So it is important to reduce the search space for efficient processing of similarity search in large time series databases. Popular techniques for efficient retrieval of time sequences in time series databases are DFT, DWT, SVD, PAA, PCA, APCA etc., In this paper we explore the feasibility of using Vari-DWT and Polar wavelet with a comprehensive analysis of the two methods as matching functions which can improve the search performance in Recent-Biased time series databases. Vari-DWT is fast to compute and requires little storage for each sequence, It preserves Euclidean distance and recency and also allows good approximation with a subset of coefficients. But it shows poor performance for locally distributed time series data which are clustered around certain values since it uses averages to reduce the dimensionality of data. Polar wavelet uses polar coordinates which are not affected from averages and so can improve the search performance especially in locally distributed time series databases. Moreover, DWT has the limitation that it works best if the length of time series 2n otherwise it approximates the signal by adding 0 to the right side of the series to make the length to be 2n which distorts the original signal. Polar wavelet works with time sequences of any length without distorting the original signal. The effectiveness of Vari-DWT and Polar wavelets are evaluated empirically on real weather data and synthetic datasets.","PeriodicalId":201931,"journal":{"name":"INTERACT-2010","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129267144","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}

Over the years so many median filters such as are separable median filters, recursive median filters, weighted median filters, max-median filters and multistage median filters were developed. Sorting networks are of major concern for real time hardware implementation of filters. Sorting is a computationally expensive operation as it consumes large area, speed and power. In this work, effective VLSI hardware implementation has been proposed as an economical solution for sorting networks in terms of area speed, power. The proposed work uses a new carry select comparator in the first section which uses compare and swap functions and its pipelined version in second section, thereby reducing the complexity of the sorting networks. The proposed Carry select comparator uses one half subractor, 7 full subractor, few multiplexers and inverters. The proposed algorithm will definitely overcome the problems by performing median calculation within 7 clock cycles. This work had been compared with existing carry select logic and its pipelined version occupies which occupies less area, consumes low power and works at 113.225 MHz for the device Devices XC2s100e–7tq144.","PeriodicalId":201931,"journal":{"name":"INTERACT-2010","volume":"324 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122711461","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}

The statistics today reveal that the current Anti-Phishing system has failed to prevent Phishing completely. In this paper an Anti-Phishing algorithm is proposed which is termed as Phish-Secure. Phish-Secure use the concept of Image Similarity Detection so as to identify the exact site the user tends to visit. Phish-Secure is simple, secure and efficient. In terms of simplicity, Phish-Secure utilize a three factor authentication system which successfully detects and prevents all Phishing attacks. In terms of security, Phish-Secure can detect not only known but also unknown Phishing attacks. Phish-Secure identifies and verifies the destination address from the outbound packet which establishes the connection with the remote server, thereby verifying whether the user is connected to the server which he actually tends to connect. In terms of efficiency, Phish-Secure will integrate a system which performs an actual URL verification and the traditional Blacklisting technique, thus reducing the time taken to detect Phishing. Thus Phish-Secure will successfully counterattack Phishing","PeriodicalId":201931,"journal":{"name":"INTERACT-2010","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131363983","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}

In order to minimize direct human intervention in such operations, the design of a remotely operated versatile Unmanned Ground Vehicle (UGV) mounted with a robotic manipulator is presented in this paper. The robustness, range and security of the communication link between the remote base station and the robot, obstacle avoidance and the real time control of the robot are some of the major issues encountered while deploying such robots in the above scenarios. In this paper, the design of a versatile UGV which leverages the already existing GSM mobile telephony network to establish a longrange, secure, fast and reliable connection with the remote base station is presented. The UGV is also mounted with a robotic manipulator with four degrees of freedom with a gripper type end-effector, which can be used for grabbing objects and thus help in search and rescue type operations. The robot is equipped with IR sensors and camera for obstacle detection and avoidance. The camera is also used to send the visual information back to the base station in real-time, allowing accurate control of and monitoring over long distances.","PeriodicalId":201931,"journal":{"name":"INTERACT-2010","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122368304","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}
