Title:	SMART TRANSMISSION POWER ADJUSTMENT ROUTING BASED ON CONNECTIVITY AND COVERAGE IN MOBILE ADHOC NETWORKS
Author:	BHARATHIRAJA.R, S.KARTHIK and V.P. ARUNACHALAM
Abstract:	The network connectivity of Mobile Ad hoc Networks (MANETs) is a multifaceted problem due to the uncertainty of the network topology. Since, wireless links have significantly limited capacity, they are affected by several errors that results in degradation of the received signal and consequently lead to the problem of coverage and connectivity. In this paper, we propose to develop a smart transmission power adjustment routing technique based on connectivity and coverage for MANETs. Initially traffic factor is calculated for each node which is based on the input and output capacity at each node and data generation rate. Then the path which has minimum transmission power and traffic factor is selected for transmission. The proposed technique also provides transmission of data to the node which is outside the coverage area. From the simulation results, we show that the proposed routing technique provides optimal power control in MANET by attaining good throughput and reduced energy consumption.

Title:	DESIGN OF AN ADAPTIVE DISTANCE-LEARNING HYPERMEDIA BASED ON LEARNER MODELING: APPLICATION FOR A COURSE IN ELECTRICAL ENGINEERING
Author:	AZIZ DEROUICH, KARIM MOHAMMED, DRISS MARJANE, FAYÇAL MESSAOUDI
Abstract:	The present article is concerned with the design, modeling and implementation of an adaptive hypermedia dedicated to distance learning. The architecture of this system is essentially based on three models: the learner model representing all data about the user, the domain model representing the pedagogical content to be taught, and the adaptation model allowing the generation and adaptation of pedagogical contents to the actual needs of the learner. Experiments in a real context, in a pilot class of thirty-two students majoring in electrical engineering, enabled us to assess our system and interpret the behavior of the learners with this mode of learning.

Title:	DETECTION OF HIGH IMPEDANCE FAULT USING A PROBABILISTIC NEURAL-NETWORK CLASSFIER
Author:	MARIZAN BIN SULAIMAN, ADNAN H. TAWAFAN, ZULKIFILIE BIN IBRAHIM
Abstract:	In this paper, a simple and efficient method for detection high impedance fault (HIF) on power distribution systems using an intelligent approach the probabilistic neural network (PNN) combined with wavelet transform technique is proposed. A high impedance fault has impedance enough high so that conventional overcurrent devices, like overcurrent relays and fuses, cannot detect it. While low impedance faults, which include comparatively large fault currents are easily detected by conventional overcurrent devices. Both frequency and time data are needed to get the exact information to classify and detect no fault from HIF. In the proposed method, DWT is used to extract feature of the no fault and HIF signals. The features extracted which comprise the energy of detail and approximate coefficients of the voltage, current and power signals calculated at a chosen level frequency are utilized to train and test the probabilistic neural network (PNN) for a precise classification of no fault from HIFs.

Title:	INDEX BASED STEGANOGRAPHY: A NEW SECURE APPROACH FOR IMAGE STEGANOGRAPHY USING TWO IMAGES
Author:	B.PERSIS URBANA IVY, P.J.KUMAR , S.SUREKA, G.UMA MAHESWARI
Abstract:	Steganography is the way of hiding data in such a way that nobody except the intended receiver can detect the presence of data and retrieve it. The most widely used method used for image Steganography is LSB modification method. Although it is a simple technique, but the probability of detecting the hidden data is high since the present Steganalysis algorithms are capable enough to detect not only the alteration in image but also the secret data hidden in image. The linear plain text hidden in an image can easily be detected. In this paper we proposed a new secure method of implementing image Steganography. Instead of using a single image for Steganography, we are using two images. In this method we are hiding the data without altering the image containing the actual data. Thus it provides more security than other methods of hiding data in the image. The proposed method can also efficiently hide large amount of data which was difficult to hide in other Steganographic methods.

Title:	ADAPTIVE CONTROL USING MULTIPLE MODELS WITHOUT SWITCHING
Author:	HAISEN KE, WENRUI LI
Abstract:	The multiple models adaptive control based on switching or switching and tuning have been developed extensively during the past twenty years, which can adapt rapidly to any unknown but constant operating environment. However, the stability of the system with multiple models cannot be easily established. Towards this goal, this paper proposes a novel multiple models adaptive controller. Unlike the prior results, the controller developed here do not require a switching scheme to guarantee the most appropriate model to be switched into the controller design. So the analysis of the stability of the closed-loop can be established easily. Besides, the N identification models are fixed, which is superior to the all adaptive identification models. Simulation results proposed to illustrate the effectiveness of the developed multiple models adaptive controller.

Title:	PERFORMANCE EVALUATION OF ROUTING PROTOCOLS IN LARGE-SCALE MOBILE AD HOC NETWORKS
Author:	JAMALI ABDELLAH, NAJA NAJIB, EL OUADGHIRI DRISS, BENAINI REDOUANE, ZYANE ABDELLAH
Abstract:	A mobile ad hoc network (MANET) is a collection of wireless mobile nodes communicating with each other using multi-hop wireless links without any existing network infrastructure or centralized administration. Efficient routing protocols can provide significant benefits to mobile ad hoc networks, in terms of both performance and reliability. Many routing protocols for such networks have been proposed so far. Amongst the most popular ones are Dynamic Source Routing (DSR), Ad hoc On-demand Distance Vector (AODV), Destination-Sequence Distance-Vector (DSDV), Temporally-Ordered Routing Algorithm (TORA, ) and Location-Aided Routing (LAR). Research efforts have not focused in evaluating the performance of these protocols when applied to large-scale wireless networks. In this paper we present our observations regarding the behavior of the above protocols, in large-scale mobile ad hoc networks (MANETs). We consider wireless mobile terminals spread over a large geographical area, and we perform extensive simulations, using NS-2 simulator.

Author:	T.R.V.ANANDHARAJAN, DEEPAK BHARGAVAN, M.A. BHAGYAVENI
Abstract:	The crunch in resources and ability to serve the interest of customers with maximum efficiency and minimum resources has led to a wide range of research in cloud resource management. Various cloud service providers currently in the market are testing several algorithms to manage their resources and has not been able to strike a balance between service quality and energy management. Through our paper we intend to strike a deal between energy and quality by maintaining both within preferred limits. We proposed an Efficient Energy Aware (EEA) analysis by introducing RHO (Ram based Host Overloading detection) algorithm. It has shown significant improvements over existing power aware host overloading detection algorithms like IQR (inter quartile range). This algorithm gave 37.26% improvement in terms of energy and 70% improvement in PDM (Performance degradation due to migration) over IQR.

Author:	DARMA PUTRA
Abstract:	This paper introduced some new techniques to extract the palmprint features based on fractal codes and fractal dimension. Four new techniques based on fractal, namely FDFC (fractal dimension from fractal codes), FDIFC (fractal dimension image from fractal code), DIFC (distance image from fractal code), and AIFC (Angle image from fractal code) are proposed.. The main idea of these methods is the forming palmprint image representation by using fractal code parameters. There are three parameters of fractal codes are used namely position of range block, position of domain block, and size of range block. Those methods have been applied for palmprint verification system. The system has been tested by using database of 1050 palmprint images, are generated from 5 samples from each of the 210 persons randomly selected. Experiment results show that our proposed methods can achieve an acceptable accuracy rate.

Title:	IMPLEMENTATION OF VIRTUALIZATION IN DATA CENTERS TO INCREASE PROFICIENCY AND PERFORMANCE
Author:	MUEEN UDDIN, ASADULLAH SHAH, RAED ALSAQOUR
Abstract:	A traditional data center is used to host computer systems and associated components. Electricity usage has become an increasing fraction of the total cost of ownership for data centers. It is difficult to reduce the electrical consumption of tier level data centers through appropriate design of the network-critical physical infrastructure and through the design of the IT architecture. This paper explains how virtualization can be implemented in data centers to increase proficiency and productivity. The paper is a guideline for data center managers to properly design and implement virtualization at different levels in data centers. It helps to achieve sustainable energy efficient data centers to ensure that electrical consumption contributes exceedingly little to the overall emission of greenhouse gases and implementing sustainable businesses.

Title:	THE MISSILE TARGET EXTRACTION IN ULTRAVIOLET IMAGES WITH NOISE AND BURST INTERFERENCES
Author:	GAO QINA, ZHU YIING, ZOU PING
Abstract:	Though ultraviolet warning systems are working at sun-blind wave-band, while this paper reveals that in the ultraviolet (UV) images of the systems for missile approaching, there exist strong noise and burst interferences coming from UV CCD electronic sensors and high gain amplifiers. The CCD interferences can not be effectively removed by classical 2-D filtering algorithms, while they will influence the detection of the missile target in the ultraviolet images. To solve the problem, unchanging the current hardware structure of UV CCD electronic sensors, this paper develops a 3-D filtering algorithm for imaging sequence based on a 3-D recursive filter, which is stable and it extracts the missile target clearly. The proposed 3-D recursive filter composes of a 2-D spatial-filtering IIR and 1-D time-filtering IIR, both are stable. The stability test algorithms are provided. The proposed 3-D recursive filter is of much less computation amount UV image sequences and it can realize fast and real-time image filtering. Simulation experiments of UV image processing have shown that the proposed 3-D filtering and related algorithms are correct effective and pragmatica1.
