Typical Battery charger mainly consists of two stages: AC to DC stage employing boost or interleaved boost converter where power factor correction is taken care by employing suitable control technique and boosting voltage level to an intermediate dc bus level. The second stage is DC/DC stage where the voltage is regulated according to the battery requirement and provides the galvanic isolation for onboard battery chargers. This paper discusses about battery charger consisting of interleaved ac/dc boost converter with average current mode control technique combined with an isolated DC/DC converter. The first stage involves in making the input power factor acceptable to the standards and regulating dc link bus voltage and the second stage provides galvanic isolation. In addition the dc-dc converter achieves ZVS turn-on, ZCS turn-off for the inverter switches and ZCS turn-on, ZCS turn-off for the rectifier diodes, thus improving the efficiency of the circuit. The prototype is simulated for 200 watts using PSIM 9.1. From the results, the overall efficiency of the battery charger obtained is around 94.7% with improved input power factor of 0.95.

This paper discusses about a nonlinear control technique employed for AC/DC PFC converter to charge the battery of PHEV. It consists of two stages, first stage is conversion from ac to dc where the power factor improvement is achieved by reducing the harmonics at the input side. In second stage, output dc voltage is boosted according to the requirement. The control law implemented in the first stage is based on discrete energy control which helps in recovering the output at a faster rate during transient period. This also helps in maintaining unity power factor at the input side. The discrete optimal control is compared with the average current mode control and the significant simulation results are presented. From the results it is depicted that the discrete energy function control has a good dynamic response for load transients compared to average current mode control.

Cloud resources like Amazon EC2 and Google Compute Engine have become an integral part of our life with their pay-per-use pricing models. On the other hand, attempts have also been made to create virtual clouds on the fly using available devices in the locality like smartphones and tablets. Such devices being equipped with powerful processors, this is a novel method of utilizing their normally unused computational capabilities. We attempt to design and develop a pricing model for such resources created for opportunistic computing. Since the values of the resources in these virtual clouds cannot be calculated, the pay-per-resource model has to give way to a pay-per-effort model. We model the scenario as a principal-agent problem with moral hazards and propose an incentive-driven Quality of Service (QoS) to ensure that the agents act appropriately. In view of the short contractual duration, we consider only deterministic contracts which are easy to understand and implement. We show that the mobile devices can be modeled as economic actors in a contractual arrangement and discuss how the optimal decisions are identified.

The human hand is a complex system, with a large number of degrees of freedom (DoFs), sensors embedded in its structure, actuators and tendons, and a complex hierarchical control. Despite this complexity, the efforts required to the user to carry out the different movements are quite small. On the contrary, prosthetic hands are just a pale replication of the natural hand, with significantly reduced grasping capabilities and no sensory information delivered back to the user. Several attempts have been carried out to develop multifunctional Prosthetic devices controlled by electromyography (EMG) signals (myoelectric hands), harness (kinematic hands), dimensional changes in residual muscles, and so forth, but none of these methods permits the “natural” control of more than two DoFs. This paper presents a review of the traditional methods used to control artificial hands by means of EMG signal, in both the clinical and research contexts, and introduces what could be the future developments in the control strategy of these devices. This paper describes a novel approach to the control of a multifunctional prosthesis based on the classification of myoelectric patterns. It is shown that the myoelectric signal exhibits a deterministic structure during the initial phase of a muscle contraction. Features are extracted from several time segments of the myoelectric signal to preserve pattern structure. These features are then classified using an artificial neural network. The control signals are derived from natural contraction patterns which can be produced reliably with little subject training. The new control scheme increases the number of functions which can be controlled by a single channel of myoelectric signal but does so in a way which does not increase the effort required by the amputee. Results are presented to support this approach.

Image segmentation is an important process to extract information from complex medical images. Segmentation has wide application in medical field. The main objective of image segmentation is to partition an image into mutually exclusive and exhausted regions such that each region of interest is spatially contiguous and the pixels within the region are homogeneous with respect to a predefined criterion. Widely used homogeneity criteria include values of intensity, texture, color, range, surface normal and surface curvatures. During the past, many researchers in the field of medical imaging and soft computing have made significant survey in the field of image segmentation. This paper aims to develop an improved method of segmentation using Fuzzy- Neuro logic to detect various tissues like white matter, gray matter; cerebral spinal fluid and tumor for a given magnetic resonance image data set. Generally magnetic resonance images always contain a significant amount of noise caused by operator performance, equipment, and the environment, which can lead to serious inaccuracies. So segmentation of such medical images is a challenging problem in the field of image analysis. Several diagnostics are based on proper segmentation of the digitized image. Segmentation of medical images is needed for applications involving estimation of the boundary of an object, classification of tissue abnormalities, shape analysis, contour detection. In particular Fuzzy-Neuro logic segmentation algorithm is used to provide satisfactory results compared to K-means, Fuzzy C-Means, Neural Network and Fuzzy logic.

Abdul Rahim, N., Paulraj M P, Adom, A. H., and S. Sathish Kumar
- Abstract
The hearing impaired is afraid of walking along a street and living a life alone. Since, it is difficult for hearing impaired to hear and judge sound information and they often encounter risky situations while they are in outdoors. The sound produced by moving vehicle in outdoor situation cannot be moderated wisely by profoundly hearing impaired community. They also cannot distinguish the type and the distance of any moving vehicle approaching from their behind. In this paper, a simple system that identifies the type and distance of a moving vehicle using artificial neural network has been proposed. The noise emanated from a moving vehicle along the roadside was recorded together with its type and position. Using frequency-domain approach, simple feature extraction algorithm for extracting the feature from the noise emanated by the moving vehicle has been developed. One-third-octave filter bands were used and the significant features from the emanated noise were extracted. The extracted features were associated with the type and zone of the moving vehicle and a multiple classifier system (MCS) based on neural network model has been developed. The developed MCS is tested for its validity. [ABSTRACT FROM PUBLISHER]
