Abstract: In a hostile area of network, it is a severe challenge to protect sink, developing flexible and adaptive security oriented approaches against malicious activities. Intrusion detection is the act of detecting, monitoring unwanted activity and traffic on a network or a device, which violates security policy. This paper begins with a review of the most well-known anomaly based intrusion detection techniques. AIDS is a system for detecting computer intrusions, type of misuse that falls out of normal operation by monitoring system activity and classifying it as either normal or anomalous .It is based on Machine Learning AIDS schemes model that allows the attacks analyzed to be categorized and find probabilistic relationships among attacks using Bayesian network.

Keywords: Firewall; IDS; IDS types ; AIDS Techniques and Bayesian concept.

Abstract: Recently, more and more attention is paid to reversible data hiding (RDH) in encrypted images, since it maintains the excellent property that the original cover can be lossless recovered after embedded data is extracted while protecting the image content's confidentiality. All previous methods embed data by reversibly vacating room from the encrypted images, which may be subject to some errors on data extraction and/or image restoration. In this paper, we propose a novel method by reserving room before encryption with a traditional RDH algorithm, and thus it is easy for the data hider to reversibly embed data in the encrypted image. The proposed method can achieve real reversibility,

Abstract: The risk of cardio vascular diseases can be identified by measuring the retinal blood vessel. The identification of wrong blood vessel may result in wrong clinical diagnosis. This proposed system addresses the problem of identifying the true vessel by vascular structure segmentation. In this proposed model the segmented vascular structure is modelled as a vessel segment graph and the true vessels are identified by using supervised classifier approach. This paper proposes a post processing step in diagnose cardiovascular diseases which can be identified by tracking a true vessel from the optimal forest in the graph given a set on constraints.

Keywords: Cardiovascular, Graph tracer, Morphology, Optimal forest, Retinal vessel.

Abstract: Currently, there are two techniques used for large-scale gene-expression profiling; microarray and RNA-Sequence (RNA-Seq).This paper is intended to study and compare different clustering algorithms that used in microarray data analysis. Microarray is a DNA molecules array which allows multiple hybridization experiments to be carried out simultaneously and trace expression levels of thousands of genes. It is a high-throughput technology for gene expression analysis and becomes an effective tool for biomedical research. Microarray analysis aims to interpret the data produced from experiments on DNA, RNA, and protein microarrays, which enable researchers to investigate the expression state of a large number of genes. Data clustering represents the first and main process in microarray data analysis. The k-means, fuzzy c-mean, self-organizing map, and hierarchical clustering algorithms are under investigation in this paper. These algorithms are compared based on their clustering model.

Title : Multimodal Medical Image Fusion Based On SVD
Country : India

Abstract: Image fusion is a promising process in the field of medical image processing, the idea behind is to improve the content of medical image by combining two or more multimodal medical images. In this paper a novel fusion framework based on singular value decomposition - based image fusion algorithm is proposed. SVD is an image adaptive transform, it transforms the matrix of the given image into product USVT, which allows to refactor a digital image into three matrices called tensors. The proposed algorithm picks out informative image patches of source images to constitute the fused image by processing the divided subtensors rather than the whole tensor and a novel sigmoid-function-like coefficient-combining scheme is applied to construct the fused result. Experimental results show that the proposed algorithm is an alternative image fusion approach.

Keywords: Coefficient-combining strategy, image fusion, sigmoid function, singular value decomposition

Abstract: In this paper an effective employee attendance management system using fingerprint is introduced. It is used to managed the attendance of employees in any organization. All organizations and institutions are established to achieve specific objectives or goals. The identification and authentication of employee is very necessary for achieving any objective or goal. To identify and authenticate the identity of an individual employee by their names, ID numbers and signatures only are not enough, because any one can misuse other's identity and this type of problem occur very often. Fingerprint can be applied for recognizing any person, because human fingerprints are unique to each person and can be regarded as some sort of signature, certifying the person's identity. This method of employee identification and authentication will improve the attendance of employees thereby improving security, productivity and skill which will in turn improve the progress of organizations.

Keywords: Employee, Attendance, Fingerprint Matching.

Abstract: This paper presents image compression technique using hybrid transform. Concept of hybrid wavelet transform can be extended to generate hybrid transform. In hybrid wavelet transform first few rows represent global features of an image and remaining rows represent local features of an image. In Hybrid wavelet matrix rows contributing to global characteristics can be varied. In the limiting case by taking kronecker product of to orthogonal component transforms, hybrid transform is generated where all rows of transform matrix represent global features and no local features are present. This hybrid transform matrix is then applied on color image. High frequency contents of transformed image are eliminated and only low frequency contents are retained to get compressed image.

Title : Efficient Routing Protocol in the Mobile Ad-hoc Network (MANET) by using Genetic Algorithm (GA)
Country : Iraq

Abstract: An Ad hoc network is a collection of wireless mobile hosts forming a temporary network without the aid of any centralized administration or standard support services. MANET can be defined using unstable network infrastructure, self-organizing network topology and independent node mobility. This becomes obtainable due to their routing techniques; in other terms, routing is a backbone for MANET. However, due to network load routing performance of MANET is degraded thus, some optimization on network routing strategy is required.

Abstract: Estimation of signal to noise ratio (SNR) of received signal and to transmit the signal effectively for the modern communication system. The performance of existing non-data-aided (NDA) SNR estimation methods are substantially degraded for high level modulation scheme such as M-ary amplitude and phase shift keying (APSK) or quadrature amplitude modulation (QAM).In this paper SNR estimation proposed method which uses zero point auto-correlation of received signal per block and auto/cross- correlation of decision feedback signal in orthogonal frequency division multiplexing (OFDM) system. Proposed method can be studied into two types; Type 1 can estimate SNR by zero point auto-correlation of decision feedback signal based on the second moment property. Type 2 uses both zero point auto-correlation and cross-correlation based on the fourth moment property. In block-by-block reception of OFDM system, these two SNR estimation methods can be possible for the practical implementation due to correlation based the estimation method and they show more stable estimation performance than the earlier SNR estimation methods.
Keywords: SNR estimation, OFDM, QAM, correlation.

Abstract: Recent advancement in wireless communication has enabled the development of low-cost sensor networks. The sensor networks can be used for various application areas (such as health, military, home and etc.,). In earlier research, an energy-efficient cluster-based adaptive time-division multiple access (TDMA) medium-access-control (MAC) protocol, named EA-TDMA, has been developed. In this work, a new protocol, named E-BMA, which achieves even better energy efficiency for low and medium traffic by minimizing the idle time during the contention period has been proposed. Simulation results for the energy consumption of TDMA, EA-TDMA, BMA, and E-BMA have been presented to demonstrate the superiority of the E-BMA protocols.

Abstract: Peer to Peer communication has become very popular these days .This popularity and increase in P2P traffic has given birth to many internet traffic management problems for service providers. One of these problems is high download traffic of P2P file sharing application for long network distances ,as current applications do not pay attention to network topology while selecting peers for sharing data .To reduce this trans network traffic various solutions have been suggested but all of them lead to compromises for upload rate, or file availability ,or external infrastructure on the internet to support the solution. This papers suggest a modified version of Adaptive search radius algorithm for BitTorrent to solve the problem , at minimum compromise to efficiency of file sharing applications .This papers shows how BitTorrent protocol react to modified adaptive search radius , as it is the most favored application for peer to peer file sharing.
Key words: P2P, Peer to Peer, Adaptive Search Algorithm, BitTorrent.
