To improve the fuel economy and range of an electric vehicle, as much as energy regeneration during braking is important. It was observed that driving harshness has a great impact on the regeneration efficiency during vehicle deceleration. On the other hand, to reduce the trip time as well as to avoid accident, the deceleration duration needs to be kept short. By realizing these conflicting objectives, in the present work an optimal deceleration is find out for a speed change using a genetic algorithm. The concerned multi-objective optimization problem (MOOP) was solved based on two approaches: considering a constant deceleration, and variable decelerations during braking. Comparative results of both the approaches are presented for a representative speed change in four driving cycles. Results of both approaches in solving the MOOP including under certain constraints, such as a desired comfort journey and maintaining a safe braking distance, suggest that multiple decelerations should be used during planned braking, where as either a constant or multiple deceleration may be taken during braking for high comfort journey and under emergency braking demand. © 2016 IEEE.

In order to ensure continuous supply of power, the reliability of power transmission line must be high. One of the requirements is to minimize the flashover of the insulators when stressed under extreme harsh environmental conditions. To ensure the reliability of the ceramic insulators, coating of Room Temperature Vulcanized Silicone Rubber (RTV SIR) on the surface of the insulator has gained a lot of attention due to its several mechanical and electrical properties. In the recent years, use of nanocomposites as dielectric materials have gained edge because of their high permittivities and low dielectric losses. The present work examines the effect of using nanofillers of Barium Titanium Oxide (BaTiO3) with RTV SIR coating on the resultant electric stress distribution over the surface of a post type insulator made of porcelain. © 2016 Taylor & Francis Group, London.

This article develops an efficient and reliable evolutionary programming algorithm, namely quasi-oppositional biogeography-based optimization, for solving optimal power flow problems. To improve the simulation results as well as the speed of convergence, opposition-based learning is incorporated in the original biogeography-based optimization algorithm. In order to investigate the performance, the proposed scheme is applied on optimal power flow problems of standard 26-bus, IEEE 118-bus, and IEEE 300-bus systems; and comparisons among mixed-integer particle swarm optimization, evolutionary programming, the genetic algorithm, original biogeography-based optimization, and quasi-oppositional biogeography-based optimization are presented. The results show that the new quasi-oppositional biogeography-based optimization algorithm outperforms the other techniques in terms of convergence speed and global search ability. © 2012 Copyright Taylor and Francis Group, LLC.

Chip formation in grinding involves high specific energy compared to other machining processes due to high negative rake angle of grains, adverse grinding process parameters and physical-mechanical properties of the workpiece material. This causes excessive friction between chip-grit and chip-bond interfaces as there are no free flow of chip between grits and work surface. It generates high heat, which can have harmful effects on workpiece surface in case of dry grinding. But single layer brazed type (BT) or galvanic bonded (GB) cBN wheel could be the solution for the above mentioned problem, as the protrusion and gap of the grits may be monitored during manufacturing. Unlike conventional grinding, the single layer counterpart produces favorable chips during grinding bearing steel in ductile mode with lesser grinding forces and specific energy. This investigation also shows that the chips of larger volume cannot be accommodated in the intergrit spaces, which are very small in the GB wheel due to dense grit distribution and shorter grit protrusion, whereas, even with such a large chip load, the BT wheel works effectively for wider and uniform spacing and larger protrusion of the grits. © 2011 Taylor & Francis Group, LLC.

Avoidance of collision in wireless ad-hoc network is important and CSMA/CA MAC protocol is playing a major role to avoid collision. CSMA/CA MAC protocol handle it using sort RTS/CTS control message. Though reliability of data transmission increase, it blocks some nodes unnecessarily due to RTS and CTS control message and also makes existence of hidden-terminal (HT) problem which reduces the network performance. In wireless Ad-hoc network the nodes are mobile, infrastructure less and communicate through their radio range. If we can reduce the number of blockage nodes the network performance will increase by utilizing those nodes as other communication's source, destination or relay. In this paper, we propose two methods by which wireless ad-hoc network performance will increase. First we propose a method for enhancement of CSMA/CA MAC protocol by unblocking the nodes using directional antenna and setting up NAV values of RTS/CTS control message considering directional antenna and modified the CSMA/CA timing diagram accordingly. The second method shows how the hidden-terminal problem is reduced by the proposed method. The analytical model explains the performance of CSMA/CA protocol with reduction of HT problem. © 2012 IEEE.

An investigation was carried out to explore the grinding capability of brazed type cBN grinding wheel on two engineering steel-bearing steel and high speed steel. The grinding forces were measured and the chips were collected and the surface features of ground cBN grinding wheel were examined by SEM. The SEM photographs showed that cBN grits were distributed uniformly on the peripheral wheel. The results indicate that material removal mechanisms are different for both the steel. In spite of high hardness of the bearing steel, the brazed type wheel was grind very effectively without having any wheel loading and rise of unusual forces. But while grinding the high speed steel; the tangential forces (proportional to the specific energy) were quite high due to hot hardness of the work material. The formation of chips was favorable in different mode of grinding condition. In long duration grinding test, the surface topography showed almost unchanged i.e. no grits pull out without having any substantial fracture. © KSPE and Springer 2012.

Quasi-symmetric 2-designs with block intersection numbers x and y, where y = x +4 and x > 0 are considered. If D(v,b, r,k,λ;x, y) is a quasi-symmetric 2-design with above condition, then it is shown that the number of such designs is finite,whenever 3 ≤ x ≤ 68. Moreover, the non-existence of triangle free quasi-symmetric 2-designs under these parameters is obtained.

This paper describes optimal power flow based on oppositional biogeography-based optimisation (OBBO) in which fuel cost, voltage deviation and power transmission loss functions are individually used as the problem objectives. The feasibility of the proposed method is exhibited for standard IEEE 30-bus and IEEE 118-bus systems and the results obtained by using the proposed approach are compared with other optimisation methods. The proposed OBBO provides results better than other heuristic techniques. The results also show that OBBO has the effectiveness and potential to solve both small and large scale OPF problems.

This work describes a condition based reporting system of Power plant components using GSM technology. In this present approach, a dedicated microcontroller based hardware unit (DHU) has been developed to continuously measure the parameters of the viz. voltage, current, speed of turbine, frequency of generation etc. of the alternator to monitor the running condition of it also. Other than the generator there are subsystems which also need continuous monitoring. In this monitoring system each equipment is connected with one such DHU which is also connected to a Global System for Mobile Communication (GSM) modem. The preliminary level of fault or abnormality in operation of each component is diagnosed by the respective DHU and the fault or abnormalities details are reported to the pre-assigned operator through an SMS service. In extreme case, the provision of equipment shut down by a return SMS is also provided. A proto-type laboratory model has been set up and is working satisfactorily. © 2012 IEEE.

Design of a novel block-backstepping based nonlinear stabilizing control law of a pendubot is presented in this paper. It is a 2-DOF underactuated with unactuated shape variable and second order nonholonomic constraint. At the onset of the design, state model of the pendubot has been transformed into the block-strict feedback form. Thereafter, a systematic approach has been utilized to devise a backstepping control law for the pendubot system, which eventually yields a control law that is more conducive to practical applications. Lyapunov stability criteria has been used to analyze the stability of the overall system. Furthermore, stability of the zero dynamics has also been investigated to ensure the global asymptotic stability of the entire nonlinear system at its desired equilibrium point. Finally, performance of the proposed control law has been studied in simulation environment. Indeed, main novelty of the proposed approach lies in the fact that a systematic block backstepping control approach has been proposed to yield a solution for the control problem of pendubot. © 2016 IEEE.
