Title	PERFORMANCE EVALUATION OF PMSM DRIVES USING DTC TECHNIQUE
Authors	JASWANT SINGH, BINDESHWAR SINGH, S.P. SINGH, MOHD. NAIM, RAHUL DIXIT
Abstract	The direct torque control theory has achieved great success in the control of permanent magnet synchronous motor. A Direct Torque Control (DTC) scheme of Permanent Magnet Synchronous Motor (PMSM) is presented. Based on in-depth analysis of PMSM mathematical model in abc frame and frame are established and the operation principle of DTC-SVPWM system, the relationships between the torque and fundamental components. A novel space vector pulse width modulation (SVPWM) method which has a feature of low harmonic is proposed. The proposed method is adopted to implement the direct torque control (DTC) of a three-phase PMSM. A large number of simulation results show that the DTC System of PMSM has fast response and good dynamic performance. Aiming at the direct torque control in PMSM Drives, in this paper explained the theoretical basis of the direct torque control (DTC) for PMSM firstly. Then explained the difference between the applications of DTC-SVPWM to PMSM. Finally the MATLAB/Simulink models were developed to examine the DTC- SVPWM for PMSM. The simulation results is presented in this paper.

Title	ANALYSIS OF VARIOUS IMAGE COMPRESSION TECHNIQUES
Authors	G.M.PADMAJA, CH.RAJYA LAKSHMI
Abstract	With the rapid development of digital technology in consumer electronics, the demand to preserve raw image data for further editing or repeated compression is increasing. Image compression is minimizing the size in bytes of an image without degrading the quality of the image to an unacceptable level. There are several different ways in which images can be compressed. This paper analyzes various image compression techniques. In addition, specific methods are presented illustrating the application of such techniques to the real-world images. We have presented various steps involved in the general procedure for compressing images. We provided the basics of image coding with a discussion of vector quantization and one of the main technique of wavelet compression under vector quantization. This analysis of various compression techniques provides knowledge in identifying the advantageous features and helps in choosing correct method for compression.

Title	MOBILE AD-HOC NETWORK: OPTIMIZATION OF ROUTING ALGORITHMS FOR MOBILITY MODEL
Authors	NITISH PATHAK, NEELAM SHARMA
Abstract	Many wireless networking problems have to be solved for the efficient design and deployment of these communications devices that operate in a Mobile Ad-hoc Network (MANET) environment. A Mobile Ad hoc Network (MANET) is an infrastructure less network of mobile devices which are equipped with a transmitter and receiver. If any node want to communicate with the other node then each node act as a router for the establishment of the route in the Mobile Ad hoc Network. Therefore, if two nodes (devices) in a Mobile Ad hoc network want to communicate with each other, then packets can be transmitted directly or through some intermediate nodes i.e. Mobile Ad hoc Network is a collection of self organized network of flexible wireless nodes without a centralized control or infrastructure. In this paper, we are comparing an optimized routing algorithm for Mobile Ad hoc Network using NS2.

Title	A LITERATURE REVIEW & RECOMMENDATIONS ON PERSONAL SOFTWARE PROCESS TOOLS
Authors	WAQAR UL HUSNAIN, SHAHBAZ AHMED
Abstract	Review papers and Survey research papers are the primary source of information that helps researcher to find updated knowledge in that domain. No systematic survey or review paper was found in the field of Personal Software Process Tools and Software Architecture Evaluation Tools. This requires the need of performing the literature review. The review conducted tries to fill the gap in the literature and recommends some suggestions for tool that support integrated Personal Software Process and Architecture Evaluation Process. Such tools will not only help individual software engineer to perform single-case holistic design case studies which are required to fill the gap in the current literature, but also help in commercial environment for reducing cost, and schedule.

Title	ANALYZING THE DETECTION OF ACTIVE ATTACKS IN WIRELESS MOBILE NETWORKS
Authors	G.M.PADMAJA, CH.RAJYA LAKSHMI
Abstract	In multi hop wireless systems, such as ad hoc and sensor networks, mobile ad hoc network applications are deployed, security emerges as a central requirement. A particularly devastating attack is known as the active attack, where two or more malicious collision nodes create a higher level virtual tunnel in the network, which is employed to transport packets between the tunnel end points. These tunnels emulate shorter links in the network. In which adversary records transmitted packets at one location in the network, tunnels them to another location, and retransmits them into the network. An Active attack is possible even if the attacker has not compromised any hosts and even if all communication provides authenticity and confidentiality. In this paper, we analyze active attack nature in mobile ad hoc and sensor networks and existing methods to detect active attacks without require any specialized hardware. This method provides an ability in establishing a way to reduce the rate of refresh time and the response time to become more faster.

Title	INTELLIGENT DETECTION OF BEARING FAULTS IN ROTATING MACHINERY
Authors	OYEDOJA, KAYODE OYENIYI
Abstract	Industrialization shows a gradual movement from manual operation of machines and tools towards their automation. This involves lateral and hierarchical integration and networking of traditionally disjointed system units into an integral whole that requires little or no human intervention. Current trend in industrial automation requires the replacement of supervision and monitoring roles traditionally performed by humans with artificial intelligent systems. More so such system requires the intelligent detection of faults as to reduce downtime and maintenance cost. This paper study the use of hybrid intelligent system in detection of bearing faults in rotating machinery, to enable predictive maintenance and move away from the traditional breakdown or planned maintenance. This result in increase in availability and thus the productivity of the machinery or system.
Keywords	Intelligent Fault Detection, Condition Monitoring, Neurofuzzy, ANFIS, Matlab, Bearing Faults.

Title	ADJUSTABLE SPEED DRIVES: REVIEW ON DIFFERENT INVERTER TOPOLOGIES
Authors	RAHUL DIXIT, BINDESHWAR SINGH, NUPUR MITTAL
Abstract	This paper presents a literature survey on adjustable-speed drives (ASD) systems which are based on the different types of inverter topologies (namely voltage source inverter and current source inverter fed ASD system). It can overcome limitations of previous speed drive systems. The proposed inverters and ASD system can operate at wide range load (even no-load) with small inductor which is very suitable for ASD system, simplify the controller design, increase the inverter modulation index M, thus, decreases the ripple current by changing the magnitude and distribution of the harmonics and further decreases the iron loss of the motor. The operation of voltage source inverter, current source inverter have been described in detail along with the PWM technique. Authors strongly believe that this survey article will be very much useful to the researchers for finding out the relevant references in the field of improvement of speed control of drives and reduction of harmonics in three phase induction motor by PWM-techniques.
