Assistive devices such as prosthetic and orthotic devices as well as micro robotic arm can perform similar operation of a human arm when these are actuated by muscle power. The generated force is transferred through an electro-mechanical system. Most of electro mechanical devices are heavy and are not compatible with muscular system. However, an ionic polymer metal composite (IPMC) has tremendous potential as an artificial muscle and is driven by a low voltage range between -3 to +3 V. In this paper, bio-mimetic actuation of IPMC is studied. The electric voltage is detected by electromyographic (EMG) signal through human muscle and is transferred to IPMC. It is observed that an IPMC shows similar behaviour and controls of a human fore arm.

In a satellite, there exist various communication subsystem like Telecommand, Telemetry and Payload data transfer. Depending on the requirements of a particular system, different modulation techniques are being used. In general, M-PSK modulation techniques are preferable as they are power and bandwidth efficient. The paper presents the digital implementation QPSK & 8-PSK modulators for satellite communication. The modulators are realized using the concept of Direct Digital Frequency Synthesis (DDFS). The use of look up table and COrdinate Rotation Digital Computer (CORDIC) algorithm is explained in details with their comparison on the basis of spectral purity and hardware requirements. The paper describes different methods of implementations of QPSK and 8-PSK modulator with comparison in terms of hardware requirement. The design of modulators are first developed, simulated and optimized on the software tool and then coded in VHDL for hardware realization. The designs are tested on Xilinx platform.

Side lobe suppression is extremely important in precisely determining the weak echo scattering region in the presence of range side lobes. This paper addresses the signal design problem for the detection of multiple/distributed targets in high resolution radar (HRR) application with improved side lobe suppression ratio. The simulation results indicate a significant improvement in terms of noise tolerance for HRR target detection; compared to conventional binary sequences

Recently, there has been a marked increase in using machine learning techniques for object detection because of its immunity to noise and variations in backgrounds. SLAM (Simultaneous Localization and Mapping) is an approach to mapping the environment in which the robot moves, by using landmarks, much like the human visual system. The application of a robust object detection system can be extended into the field of SLAM by using these as powerful visual landmarks. While the traditional approach to SLAM (based on sensors like the SONARs or LASERs) can provide a good perception of depth, they cannot form effective landmarks. The output of these devices contain the range data mapped on a 2D space. The landmark has to be significant to show up as a pattern and hence only significant landmarks get extracted. While the visual information may be more than enough to form very good landmarks, the required computational resource increases way beyond the realm of the present day embedded processors. We use GPUs (Graphic Processing Units) to process the visual information since they have been very successful in doing real-time rendering for graphics application which involve similar mathematics. The presence of a large number of cores makes this a challenging problem to solve as programming them can be quite complex to exploit the full bandwidth of these processors. Much work is going on to integrate these units into embedded devices which make it feasible to solve the problem of visual SLAM.

Service Oriented Architecture (SOA) can be thought of as a way of defining and implementing applications that deals with the intercommunication of loosely coupled, coarse grained, reusable artifacts. Our previous studies employ increased frequency of a cluster in several processes as the only measure for forming a service. In this paper, we provide an alternative strategy for deciding if a single cluster is service worthy by examining the local and global structure of the workflow.

This paper deals with continued fraction expansion (CFE) based indirect discretization scheme for finding the rational approximation of fractional order differentiators and integrators and their discretized transfer functions. Indirect discretization approach is used for Al-Alaoui’s Optimized four segment rule and Simpson 1/3 rule based differentiators and integrators of order ½ and ¼[15]. These rational transfer functions are first stabilized for minimum phase then the resultant rational approximation is discretized by using s to z transforms. The curves for their magnitude responses, absolute magnitude errors and the phase responses are drawn with the help of MATLAB. These curves are then compared with ideal characteristics of differentiators and integrators.

In context with the recent developments in the understanding of text semantics at machine level, this paper is an attempt to extract some of the most crucial fragments that play a key role as semantic units in natural language text. The context is intuitively extracted from typed dependency structures basically depicting dependency relations using the relevant Part-Of-Speech tagged representation of the text. These relations imply deep, fine grained, labeled dependencies that encode long-distance relations and passive information. The present work focuses on extracting the key noun phrases participating both in subject and object roles that are intended to be subsequently used in framing sentential components for model answers in any selected working domain.

In this work the image is segmented effectively based on texture feature by reducing the noise. For effective image segmentation Expectation-Maximization (EM) algorithm based on Gabor filter is used. The EM algorithm is applied on 2D Ultrasonic image of uterus and tested. The Gabor function has been recognized by its multiresolution properties and the precision of locating the texture features in the spatial domain. The approach consists of two steps: finding an effective and discriminative set of texture features using Gabor filters and EM based image segmentation. The work is simulated using MAT LAB (Matrix laboratory).
