This paper describes the simulation of a single phase induction motor by ac chopper, which uses asymmetrical PWM technique to reduce the harmonics present in the motor current. The flow of power to the motor is controlled by a switching action of the power switches, which thereby control the speed of the induction motor. In this paper ac chopper module uses the IGBT as a power switch because of having more advantages over other power switches(MOSFET,THYRISTOR ETC) The main objectives of our project are to maintain the speed constant at different load condition. The simulation is carried out in MATLAB/SIMULINK with split phase induction motor.

Increasing demands of process automation for un-manned manufacturing attracted many researchers in the field of on-line monitoring of machining processes. In view of this, extensive research work is taking place world-wide in the area of on-line tool condition monitoring system. Tool wear is the most undesirable characteristic of machining processes as it adversely affects the tool life, which is of foremost importance in metal cutting owing to its direct impact on the surface quality of the machined surface, and its dimensional accuracy, and consequently, the economics of machining operations.Tool wear has negative effects on surface quality, dimensional precision of work piece, and may even cause a harmful effect on safe operation of total machining system. According to the research, about 20% machine downtime is caused by the tool wear.In addition, the cost of cutting tool and tool changing is about 3–12% of the total machining cost and method for on-machine tool progressive monitoring of tool flank wear by processing the turned component. Therefore, methods for cutting tool wearin an over view of the maximum use of cutting tools. With an effective monitoring system, the wear and damages to the machine tool, downtime, lead time and scrapped components can be avoided. This paper provides brief overview on tool condition monitoring.

This paper investigates about the Bond-Slip behaviour of steel rebars in reinforced concrete for Plain and Ribbed reinforcing bars. Bond strength is influenced by the rib pattern of the bar and RILEM suggested some recommendations to increase the bond strength of the concrete. Two grades of concrete M25 and M30 were casted. A total of eight specimens were casted using 25mm bar. The bond stress-slip response was studied. Graphical comparisons were done between the Load vs Slip and Load vs Displacement for RILEM standards. Slip was measured using LVDT at both ends. Ribbed bars showed better bond strength compared to plain bars and bond strength obtained from both tests produced same results.

Robotic Navigation
The present paper deals with the navigation of multiple wheeled robots working in a common dynamic environment in a decentralized manner. Two different motion planning approaches have been proposed to solve the said problem. In Approach 1, automatic design of a Mamdani-type Fuzzy Logic Controller (FLC) using a binary-coded Genetic Algorithm (GA) has been considered. On the other hand, a potential field- based motion planner has been developed in the next approach. Since, the robots are agents and all the time competition is not good, a strategic approach has been proposed to solve the conflicts related to coordination among agents. Performance of the developed approaches have been tested through computer simulations. Computational complexity of both the approaches are also compared to see the feasibility of their on-line implementations. It has been observed that proposed coordination strategy along with the developed motion planners are found to generate movement of the robots in a human-like manner.

One of the main goals of the metal-mechanical industries is the reduction of the production costs through the productivity increase. In the attempt to reach this goals, many researchers have been used the hot machining method. This method consists, basically, in the heating of the work piece hundreds of degrees Celsius above room temperature with aid of an external source of heat. Thus, the reduction of the shear stress of the material of the piece is gotten and, hence, is possible to obtain a smaller wear of cutting tool in relation to the conventional machining. This paper presents a review of hot machining, where the different techniques are presented together their results. This review paper presents a survey on variation in process parameter i.e. temperature, cutting speed, feed etc. and their effect on surface roughness, hardness, material removal rate, tool wear, tool life.

Signal Coordination of consecutive intersections were carried out by thumb rule by coupling the indices depend on ratio of traffic volume to distance as well as modelled flow. As eminent resolution data is easily available from intersections, it becomes desire to analyse the actual stream of vehicle flow better to characterise is signal coordination desirable ? As increase in vehicular population causes not only congestion, delay in travel time but also pollution at road. To handle the influence of these travel demand at urban area, signalised intersection present on arterial roads have minimum resistance to flow of traffic for minimising the travel time. If signalised intersections are coordinated then the time pollution will be optimum, air and noise pollution as well. This paper composed of analysis of the previously developed methodology and results of delay caused due to pre-timed two way signal coordination with least time pollution and environmental pollutions. Traffic efficiency is affected by placing the signalised intersections at close continuous manner. This paper concluded with most suitable methodology and simulation techniques for coordination to reduce the time pollution as well as improve the traffic efficiency

CLOUD COMPUTING
Cross cloud computing is the piece of software that is portable and can run on multiple platforms without human intervention. Cross cloud service composition provides a concrete approach that is capable for large scale big data processing. We propose a privacy-aware cross-cloud service composition method, named Hire Some-II (History record-based Service optimization method) based on its previous basic version Hire Some-I. In our method, to enhance the credibility of a composition plan, the evaluation of a service is promoted by some of its Qos history records. Using Hiresome-II technique time consumption for searching of data can be reduced. Cloud computing is an internet based computing, which shares resources, software and information are provided to computers and other devices on demand, in this security is the major concern.
Keywords : Cloud, Cross Cloud, Hiresome-II, Indexed Based Searching, Service Composition.

Heat Transfer Enhancement
Heat transfer augmentation without considerable pressure drop is one of the most important issues now a days. The different active and passive methods are used for the same. One of the passive technique is use of dimples. A depression forming recesses on a flat surface is considered as a dimple. Variation in dimple geometry results in various heat transfer and friction characteristics. Introducing the dimples on the surface not only increases the surface area available for heat transfer but also reduce the hydrodynamic resistance for the fluid flow over the surface, resulting in less pressure drop. The present work is based on experimental investigation of the forced convection heat transfer over the V-shaped dimpled surface. The experiments were performed on 150mm × 150mm × 15mm aluminium plate with V- shaped dimples with pitch 3.2D, where D = diameter of dimple. V-dimples with δ/D = 0.2, 0.3, 0.5 are investigated, where δ= dimple depth. The experimentation was carried over a rectangular duct with aspect ratio 3:2. Heat transfer coefficient, Nusselt Number, friction factor and overall thermal performance of dimpled surface are compared with those from flat surface under same conditions. It is found that dimpled surface show 30- 45% enhancement over a flat plate. The maximum enhancement is observed in δ=0.3D in inline pattern. The dimpled surface with δ=0.5D shows minimum enhancement. Maximum frictional losses are observed in δ=0.5D dimpled surface and minimum in δ=0.2D dimpled surface. The overall thermal efficiency goes on increasing with increasing Reynolds number for all cases. The enhancement was verified using CFD analysis using ANSYSIS-15 ICEM software using k-ε turbulence model.
