Similarity search involves both subsequences matching and whole sequence matching. In this paper, we present an approach which consider on how many dimensions the data point is similiar to the query point, the average distance of these dimensions of data point to the query point as well as efficiency with respect to time and space required with the dramatic increment of data size. The proposed approach involves dynamic selection of input parameters, covering both subsequences matching and whole sequence matching, suppressing the impact of high dissimilarities in few dimensions. Thus our proposed approach can help improving performance of existing data analysis technologies, such as financial market analysis, medical diagnosis and scientific and engineering database analysis as tremendous amount of data is generated in these disciplines.","PeriodicalId":319467,"journal":{"name":"2012 International Conference on Communication, Information & Computing Technology (ICCICT)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114239650","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}

It has become a medium through which people openly express their views on various subjects. These opinions contain useful information which can be utilized in many sectors which require constant customer feedback. Analysis of the opinion and it's classification into different sentiment classes is gradually emerging as a key factor in decision making. There has been extensive research on automatic text analysis for sentiments such as sentiment classifiers, affect analysis, automatic survey analysis, opinion extraction, or recommender systems. These methods typically try to extract the overall sentiment revealed in a sentence or document, either positive or negative, or somewhere in between. However, a drawback of these methods is that the information can be degraded, especially in texts where a loss of information can also occur. The proposed method attempts to overcome the problem of the loss of text information by using well trained training sets. Also, recommendation of a product or request for a product as per the user's requirements have achieved with the proposed method.","PeriodicalId":319467,"journal":{"name":"2012 International Conference on Communication, Information & Computing Technology (ICCICT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129426925","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}

To fulfill the criteria of the all time connectivity, the mobile station (MS) should be connected with a base station (BS) during its operating mode, irrespective of its mobility. When a MS travels within the cell, no special technique is required to maintain its connectivity. But when a MS travels out of the coverage area of its current BS and tries to associate with another BS, a delay occurs during the handover of connection which leads to a failure of connection. Throughout the last few years plenty of researches had been done to reduce this handover delay by reducing the scanning delay as the scanning process causes ninety percent of the total handover delay. In this paper, we propose a new scanning technique where the hexagonal cell is divided in three angular segments and for each segment two neighbour BSs are reserved for handover. MS will measure its distance from the reserved BSs at fixed time intervals and the handover of connection will be performed to the nearest BS when the handover will be required. Our simulation results show the effectiveness of our proposed scheme in practical field.","PeriodicalId":319467,"journal":{"name":"2012 International Conference on Communication, Information & Computing Technology (ICCICT)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130460519","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}

This paper proposes an algorithm through which the best parity check matrix is obtained for irregular low density parity check codes, which reduces the Bit Error Rate ,Frame Error Rate and computational complexity. Tanner graph also called a bipartite graph format in an Low Density Parity Check (LDPC) code design contains many short cycles; it will produce a computational complexity in a code design process and it degrades the code performance. To overcome this effect, we proposed an new algorithm which obtains a best final parity check matrix. Throughout the paper we will give the detailed description of an efficient algorithm proposed. The complexity is studied graphically and analytically. Using proposed algorithm, cycles of length four observed in corresponding matrix are removed. Each matrix is evaluated over a noisy Additive White Gaussian Noise (AWGN) channel. Bit Error rate and Frame error rate is calculated. The results are compared with randomly generated best parity check matrix. Simulation results shows that proposed method successfully overcomes the computational complexity and meets the near Shannon limit.","PeriodicalId":319467,"journal":{"name":"2012 International Conference on Communication, Information & Computing Technology (ICCICT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130305616","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 quality of restoration is also highly dependent on the accuracy of point spread function (PSF) kernel estimation. In this paper, we present a Radon transform based motion blur parameter estimation method under both spatial-invariant and variant blur consideration. The experiments performed on simulated motion blurred images show that taking Radon transform of the spectral gradients of blurred images improve estimation accuracy even in presence of noise. Compared with already existing Radon transform based PSF estimation schemes, our method successfully performs PSF estimation even for typical non-uniform motion blurred imagery.","PeriodicalId":319467,"journal":{"name":"2012 International Conference on Communication, Information & Computing Technology (ICCICT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130864047","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 cognitive radio has been proposed as the future technology to meet the ever increasing demand of the radio spectrum by allocating the spectrum dynamically to allow unlicensed access on non-interfering basis. Conventional sensing methods usually relate to sensing the spectrum in three dimensions viz. frequency, time and space. However, there are other dimensions `Angle' and `Code' that need to be explored further for spectrum opportunity. This paper investigates the performance of Angle of Arrival (AoA) estimation algorithms like Bartlett's, Capon, MUSIC, Root-MUSIC and ESPRIT in cognitive radio networks. The results show that the performance of the algorithms improves with increasing number of array elements, increasing number of snapshots and increasing signal-to-noise ratio. This new approach of AoA estimation of licensed user, improves frequency reuse capability and increases channel capacity by multiplexing multiple users (licensed and unlicensed) into the same channel at the same time in the same geographical area by forming the beam of unlicensed user in the direction other than the licensed users' AoA direction.","PeriodicalId":319467,"journal":{"name":"2012 International Conference on Communication, Information & Computing Technology (ICCICT)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127984181","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 the proposed system it is achieved with the Android smart phone. Heart rate variability (HRV) analysis is well known to give information about the autonomic heart rate modulation mechanism. In order to avoid erroneous conclusions, it is of utmost importance that only sinus rhythms are present in the cardiogram. Therefore, preprocessing of the RR interval time series is necessary. This paper presents an advanced automated algorithm to preprocess RR intervals obtained from a normal ECG. Validation of this algorithm was performed on recorded ECG signals by holter recorder and MIT-BIH database.
