Abstract: Non-Audible Murmur (NAM) is a very quietly uttered speech received through the body tissue with the use of special acoustic sensors (i.e., NAM microphone) attached behind the talker’s ear. Analysis of NAM speech has been made only using HMM (Hidden Markov Model) and GMM (Gaussian Markov Model). In this paper, study of analysing acoustic speech and NAM speech will be made using Wavelet transform. Since, wavelets have the great advantage of being able to separate the fine details in a signal. It allows complex information such as music, speech, and patterns to be decomposed into elementary forms at different positions and subsequently reconstruct it with high precision. Upon analysing the Normal speech, NAM speech will also be analysed using the same wavelet transform. The accuracy of words obtained from the two methods will be compared to determine the efficiency of using Wavelet transform in recognizing NAM speech.

Abstract: This paper presents a speech-model using the Linear Predictive (LP) residual signal and Maximum Likelihood Estimator (MLE). With this model an accuracy of the reverberation time estimation can be improved. During past decade, the reverberation time estimation was performed using only maximum likelihood detector, which resulted in excess time of estimation. For the purpose of estimating room acoustics, it is very essential to calculate the reverberation time more accurately. The study shows that Direct-to-Reverberation Ratio can also be calculated in accordance to the estimation of Reverberation Time. These two parameters can be made useful in the application of hearing aid.

Abstract: Increasing demand in high transmission capacity has to be satisfied by a better use of existing frequency bands and channel conditions. One of the recent technical breakthroughs, which will be able to provide the necessary data rates, is the use of multiple antennas at both link ends. Spatial Modulation (SM) is used in wireless systems, which can offer good data rates and error performance with a moderately low system complexity. Adaptive modulation schemes for fading channels are usually required to fulfil certain long-term average BER targets. Performance of SSK modulation increases for increasing values of the target bit rate and of the number of antennas at the receiver. This modulation has the same robustness to channel estimation errors as conventional modulation schemes. Hence a new modulation called CoMP (Coordinated MultiPoint)–SSK modulation is proposed. CoMP-SSK modulation can provide very high bit rates at the cost of network cooperation. In this paper bit error rate performance of some popular modulation schemes have been studied and compared with their results.

Abstract: The architecture of two-tiered sensor networks, where storage nodes serve as an intermediate tier between sensors and a sink for storing data and processing queries, has been widely adopted because of the benefits of power and storage saving for sensors as well as the efficiency of query processing. However, the importance of storage nodes also makes them attractive to attackers. SecureQ Proto-filter acts as protocol as well as filter. SecureQ prevents attackers from gaining information from both sensor collected data and sink issued queries. To improve performance, SecureQ will be used to reduce the communication cost between sensors and storage nodes. SecureQ also allows a sink to detect compromised storage nodes when they misbehave. To preserve privacy, SecureQ uses a novel technique to encode both data and queries such that a storage node can correctly process encoded queries over encoded data without knowing their values. To preserve integrity, Truth confirmation algorithm to generate integrity verification information so that a sink can use this information to verify whether the result of a query contains exactly the data items that satisfy the query.

Abstract: As Mobile communications become increasingly sophisticated and ubiquitous .traditional mobile billing with its implicit trust relationships Will no longer be adequate .with a large number of different sizes mobile Networks, a huge variety of value added service provider and many millions Of roaming user, it is desirable to remove any unnecessary trust in order to Increase security and provide incontestable charging. Billing allowance each Party involved in a call to eventually receive a share of the revenue generated. An examination of network billing techniques reveals a number of critical shortcomings and emerging problem. Address these issue by designing a multi-party electronic payment scheme that allows are parties involved in a Call to be paid in real-time. The mobile user releases an ongoing stream of low valued micro payment tokens into the network in exchange for the requested Services. Dynamic pricing is supported by the association of a pricing contract With the call which specifies the cost of leg of the call route. Any user with a mobile device and monetary value can use and pay for network access and services in any mobile network into which they roam. The need to authenticate the user or contact a distant home network for billing purposes. Extensions to the basic scheme provide mobile wallet functionality and allow user-to-user payments. In addition solutions are designed to cope with frequent handovers between independent piccolos, to aggregate several payment streams into one in the core network, and to inter-work with networks using legacy billing techniques. A detailed survey of micropayment techniques forms part of the design Process and a number of a new micro payment contribution result from observation made. In order to choose appropriate techniques for payment a performance comparison of micropayment schemes is presented based on benchmark measurement taken for the underlying cryptographic algorithms. The multi-party micropayment protocol is prototyped wireless environment where it is used to pay for user traffic from existing internet applications. the proposed scheme has the potential to revolution mobile communication by allowing the emergence of many independent inexpensive high speed picocell networks and by allowing any network entity to sell value added services. Mobile user will be able to select the most appropriate access network and services wherever they roam, paying all parties for resources as they are provided.

Abstract: Energy Conservation is a very important design issue for mobile ad hoc networks (MANET) since mobile nodes are powered by batteries with limited capacity. The typical routing protocols of MANETs are mainly the shortest path routing protocols and do not consider the energy aware issue. Power failure of a node affects the overall network lifetime. So this paper describes improvement of the conventional routing protocol by utilizing high energy paths in the network. We present a comparative analysis of existing AODV protocol and energy efficient AODV protocol which is modified to improve network lifetime as well as packet delivery ratio. Simulation results indicate that the routing scheme of proposed method is more efficient than existing well-known routing protocols.

Abstract: This paper proposes an efficient and template based technique for automatic ear detection in a side face image. The technique first separates skin regions from non-skin regions and then searches for the ear within skin regions. Ear detection process involves three major steps. First, Skin Segmentation to eliminate all non-skin pixels from the image, second Ear Localization to perform ear detection using template matching approach, and third Ear Verification to validate the ear detection using the Zernike moments based shape descriptor. To handle the detection of ears of various shapes and sizes, an ear template is created considering the ears of various shapes and resized automatically to a size suitable for the detection.

Abstract: Plants are among the earth's most useful and beautiful products of nature. Plants have been crucial to mankind's survival. The urgent need is that many plants are at the risk of extinction. About 50% of ayurvedic medicines are prepared using plant leaves and many of these plant species belong to the endanger group. So it is indispensable to set up a database for plant protection. We believe that the first step is to teach a computer how to classify plants. Leaf /plant identification has been a challenge for many researchers. Several researchers have proposed various techniques. In this paper we have proposed a novel framework for recognizing and identifying plants using shape, vein, color, texture features which are combined with Zernike movements. Radial basis probabilistic neural network (RBPNN) has been used as a classifier. To train RBPNN we use a dual stage training algorithm which significantly enhances the performance of the classifier. Simulation results on the Flavia leaf dataset indicates that the proposed method for leaf recognition yields an accuracy rate of 93.82%

Abstract: Ternary Content-Addressable Memories (TCAMs) are becoming popular for designing high-throughput forwarding engines on routers. They are fast, cost-effective and simple to manage. However, a major drawback of TCAMs is their large power consumption. This paper presents architectures and algorithms for making TCAM-based routing table more power efficient. The proposed architecture and algorithms are simple to implement, use commodity TCAMs, and provide worst- case power consumption guarantees (independent of routing table contents). The most existing TCAM-based forwarding engines involve shifting TCAM entries when the forwarding table is updated, typically incurring a lengthy update duration. And also proposed a TCAM-based longest prefix forwarding engine with fast updating. The key idea behind the design is to maintain the forwarding table in a TCAM according to the Minimum Independent Prefix Set.

Associate Professor2 , Dept.of CSE, CSIT, Durg, India
Abstract: Digital Image Inpainting is challenging and interesting research area, because one has to restore the area which is not visible but important to visually complete the image. This technique has found widespread use in applications such as restoration, error recovery, multimedia editing, and video privacy protection. Because of the strong human visual perception, a very effective technique is required for digital image inpainting. Most automatic techniques are computationally intensive and unable to repair large holes. Existing methods use interpolation methods where surrounding information is not adequate for image interpolation and chain codes for contour matching for small damaged area reconstruction. But, reconstructed image has not given up to the mark results. This paper proposed an effective inpainting technique in order to improve the inpainting result. The method proposed in this paper uses Run Length Coding for shape tracking along with CNN approach, because Run Length coding track the shape of an image, which is better than the several methods available for shape tracking.

Abstract: Communications through frequency-selective fading channels suffer inter-symbol interference (ISI), which limits the data rate. Complex equalizers are usually needed to compensate for the channel distortion. Orthogonal Frequency Division Multiplexing (OFDM) divides the channel spectrum into many sub-bands, each of which carries low-rate data. Since each sub- channel is narrow band, communications through it experience only flat-fading. The sub-channels are separated with the minimum space required by channel Orthogonality. Therefore, a large number of low-rate data streams can be transmitted in parallel and aggregate to a high-rate one. Channel estimation and prediction algorithms are developed and evaluated for use in broadband adaptive OFDM downlinks over fading channels for vehicular users. Accurate channel estimation may be obtained by using a combined pilot aided and decision-directed approach based on Recursive filtering and prediction. The correlation properties of the channel in both time and space are taken into account. Kalman performance at much lower computational complexity is attained with recently developed constant gain adaptation laws. We present and evaluate a state-space realization of such an adaptation law, with computational complexity of the order of the square of the number of parallel tracked pilot subcarriers. In an adaptive OFDM system, prediction of the channel power a few milliseconds ahead will also be required. Frequency-domain channel estimates can be transformed to the time domain, and used as regressors in channel predictors based on linear regression. We also make a preliminary evaluation of the direct use of complex channel prediction in the frequency domain for channel power prediction.

Abstract: An efficient and fully robust group key agreement protocol (GKA) enables a group of authenticated users to communicate over a reliable broadcast communication medium. All non-faulty nodes will form a cyclic group and hence have the same view of the message which is broadcasted and the faulty nodes cannot view that message. The standard encryption-based group key agreement protocol can be robust against an arbitrary number of node faults, because the performance deteriorates if some nodes fail during the protocol execution..By making each node to enter with the help of a nonce which is an arbitrary number that is used only once in a cryptographic communication and it will protect the malicious insiders that may disturb the group communication. The elliptic curve digital signature algorithm is used for establishing the group key and the proposed protocol has O(log n)-sized messages and expected round complexity close to 2, assuming random node fault and also it is secure under the (standard) Decisional Square Diffie-Hellman assumption.

Abstract: Information Security is the process by which an organization protects and secures data communications and storage. Biometrics is a field of science which deals with the positive identification of unique individuals based on their physiological or behavioural characteristics. Each biometric has its strength and weakness. No single biometric is expected to effectively meet the requirements of all applications. Biometric products provide improved security over traditional electronic access controls. While some technologies have gained more acceptance then others, it is beyond doubt that the field of access control biometrics has gained a measure of acceptance. In certain situations, the user might find one form of biometric identification is not exact enough for identification. Unimodal biometric system have to contend with a variety of problems such as noisy data, spoof attacks, non-universality, intra-class variations etc. These limitations can be overcome by Multimodal biometric system. Multimodal biometric technology uses more then one biometric identifier to compare the identity of the person for better security. This article describes about Multimodal Biometric technologies, modules and levels of fusions, design issues and modes of operations etc.

Abstract: One of the challenging issues for Orthogonal Frequency Division Multiplexing (OFDM) system is its high Peak-to- Average Power Ratio (PAPR). In this paper, we review and analysis different OFDM PAPR reduction techniques, based on computational complexity, bandwidth expansion, spectral spillage and performance The proposed scheme is termed sub-block complement coding (SBCC). Performance results obtained with SBCC are given and compared with that of the standard complement block coding (CBC), cyclic coding (CC), simple block coding (SBC), modified simple block coding (MSBC) and simple odd parity code (SOPC) for the same purpose. The results show that, at the same coding rate 3/4, the proposed scheme can achieve almost the same performance as the cyclic code but with lower complexity. But under the same coding rate, the PAPR reduction obtained by using SBCC is better than the rest schemes. The flexibility on choosing the coding rate and low complexity makes that the proposed scheme SBCC is more suitable for the large frame size with high coding rate and can provide error detection..We also discuss some methods of PAPRReduction.

Abstract: Experiments were performed to investigate the storage I/O performance of pNFS file system protocol using network direct attached hard disk drives as its storage subsystem. Comparison experiments were done to NFS4.0 and NFS4.1 with pNFS in order to further investigate the scalability of the two network file systems. It is found that NFS4.1 preserves the scalability as storage capacity is increased while NFS4.0 loses its scalability rapidly as its storage capacity is increased. It is also found that NFS4.1 shows, on average, over 4 times higher I/O speed than NFS4.0 when both systems uses the same set of network direct attached hard disk drives in our experiments.
