To spot exact locality of tumor and its data being an essential task. To find the tumor, magnetic resonance image has used. FMRI (Functional Magnetic Resonance Imaging) is non-invasive procedure is to see the brain activity and to calculate of blood circulation level in the brain. The FMRI data are time series of 3D-dimensional volume images of the brain based on interaction pattern. This data is traditionally analyzed within a mass-univariate framework essentially relying on classical inferential statistics. Segmentation of FMRI plays a vital role to acquire the data of brain activities of the human brain. Feature Selection is a complicated to handle in Interaction pattern. To overcome the difficulty of the feature selection process, we use the Principal Component Analysis (PCA). PCA is a technique to pre-process the data before carrying out any data mining responsibilities, e.g., categorization and grouping. By this PC Analysis, profitable predictors are achievable in FMRI data. Using the features selected from PCA, we present a clustering novel technique. Based on this new cluster notion interaction K-means (IKM) have applied. IKM is a well-organized procedure for clustering. In this paper, Trained MRI data has taken out using the PC Analysis and IKM technique have applied over the specified data. By this, improvement has conquered in the performance in terms of accuracy and complexity in multivariate data.","PeriodicalId":174192,"journal":{"name":"2015 International Conference on Communications and Signal Processing (ICCSP)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132670028","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}

They provide the shared memory abstraction in systems with physically distributed memories, and consequently combine the advantages of both approaches. Distributed shared memory is the abstraction that supports the shared memory in a physically non-shared (distributed) architecture. Shared memory is a simple yet powerful paradigm for structuring systems. Recently, there has been an interest in extending this paradigm to non-shared memory architectures as well. For example, the virtual address spaces for all variables in a distributed variable-based system could be viewed as constituting a global distributed shared memory. The Distributed shared memory system is designed on the basis of page-based, shared-variable-based or object-based access. There are certain advantages and disadvantages of each access methodology. We propose a shared variable based DSM model for managing distributed shared memory. These paper also present implementation levels with its several issues require to be consider. We have presented an implementation of this model in the context of a linux operating system.","PeriodicalId":174192,"journal":{"name":"2015 International Conference on Communications and Signal Processing (ICCSP)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130352213","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}

We realize the MIMO profile using four transmit antennas at the base station and three receive antennas at the mobile station. We achieve bandwidth efficiency using discrete wavelet transform (DWT). Further we implement Arnold's Cat Map (ACM) encryption algorithm for secured medical transmission. We consider celulas as medical image which is used to differentiate between normal cell and carcinogenic cell. In order to accommodate more users' image, we consider IDMA as accessing scheme. At the mobile station (MS), we employ non-linear minimum mean square error (MMSE) detection algorithm to alleviate the effects of unwanted multiple users image information and multi-stream interference (MSI) in the context of downlink transmission. In particular, we investigate the effects of three types of delay-spread distributions pertaining to Stanford university interim (SUI) channel models for encrypted image transmission of MIMO-IDMA system. From our computer simulation, we reveal that DWT based coded MIMO- IDMA system with ACM provides superior picture quality in the context of DL communication while offering higher spectral efficiency and security.","PeriodicalId":174192,"journal":{"name":"2015 International Conference on Communications and Signal Processing (ICCSP)","volume":"49 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114003991","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}

By using LABVIEW software and vision builder software the quality of an object in terms of linearity can be investigated by using different image processing techniques such as image compression, image restoration etc. along with the various image processing functions like special filters and classifiers to compute the optimum results. Using smart camera in the inspection system the static as well as the dynamic object is captured in fraction of seconds without any blurs; as a result the optimum image quality without any distortion is obtained for better analysis. The proposed system is very precise, accurate and flexible with reasonable development cost compared to other model. With the aid of an Industrial robotic system with simulation software the object is replaced immediately when the same is rejected by the machine vision model.

For data analysis the Poincaré plot in spherical coordinate is used. Each of the plots obtained from second order differences form a single cluster looking almost like an ellipse having some outliers. We observe that the volume of the cluster is reduced remarkably in the data of the on music state as compared to the data of pre music state; further the amount of reduction is not the same for all the subjects. This proves that music has some definite common effect on human physiology. Our study shows that this particular type of music gives a complete different physiology.

Basically this is a permutation based combinatorial optimization problem which involves allocating a set of tasks on a set of processors so as to minimize the makespan and ensures tasks to meet their timing constraints. Conventional approach to meet fault-tolerance (FT) in scheduling RT tasks based on traditional heuristic approach yields poor performance, like inefficient processor utilization and higher task rejection. The primary-backup (PB) scheme is a popular approach used as a fault-tolerant technique to schedule RT tasks with guarantee to meet their deadlines despite presence of fault. In this paper, we propose a novel scheduling algorithm using discrete elitist multi-objective ant colony optimization (DEMACO) technique for providing FT in multiprocessor environment. Exhaustive simulation study reveals that the proposed primary-backup based fault-tolerant scheduling (PBFTS) scheme using DEMACO outperforms other traditional fault-tolerant scheduling schemes in terms of performance, system utilization and efficiency.","PeriodicalId":174192,"journal":{"name":"2015 International Conference on Communications and Signal Processing (ICCSP)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123287679","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}
