The Experimental Investigation and Analysis of Spot Welding Process Parameters for Maximum Tensile Strength

This experimental study is based on an investigation of the effect of welding parameters on tensile shear strength in the resistance spot welding (RSW) process and optimization of welding parameters. The experiment conducted under varying parameters like forces, currents and weld times without disturbing water flow and room temperature. The setting of welding parameters was determined by using Taguchi experimental design of L9 orthogonal array method. The combination of the optimum welding parameters have determined by using analysis of Signal- to- Noise (S/N) rario. The experimental result clearly shows that it is possible to increase tensile shear strength of a joint by the combination of suitable welding parameters. Hence the experimental result proved the validity of the used taguchi method for enhancing the welding strength performance and optimizing the most suitable welding parameters in resistance spot welding operations.

Language Proficiency of English among +2 students in relation to their Locality and Stream of Study

The study compares the Language Proficiency of English among +2 Students of Shimla district in relation to their Locality and Stream of Study. A Sample of 600 students was selected randomly from the Shimla district of Himachal Pradesh. For comparing the data 2X2X2 ANOVA statistics technique was used. The result revealed that significant differences existed among rural and urban science and arts stream of English and Hindi medium students

Smart Surveillance Analysis System Using Hadoop

Security and time play very important role in everyone's life. So it is required to develop a system which will make an individual feel protected. In case if any changes are detected then it can be analyzed in a minimum time. Up to some extent, environmental changes are also detected. The first task of multi-camera surveillance is Automation object detection analysis. Changes in the CCTV recording are detected using OpenCV and they are represented by using particular colors. On single machine it will take ample of time to analyze the CCTV video recording, this drawback is overcome by using Hadoop. Hadoop has a feature of centralized server processing and distributed processing. The analysis is done using algorithms. Color histogram, Mean square difference and SSIM index are the algorithms used for frame comparison. An algorithm with the accurate result is preferred. Experimental results show a reduction in analysis time.

Ac-Dc Optimal power flow Based nodal pricing in deregulated power system

In This Paper an AC-DC Optimal power flow based nodal pricing methodology is presented. The active and reactive power generated and purchased at each bus is calculated by using OPF. Also, nodal prices can be obtained by using OPF. Here the nodal prices are important because they reflect the marginal generation and load at each bus. In general, these prices are also known as locational marginal Prices and spot prices. In this paper, for the load flow analysis, a well-known Newton-Raphson method is used and is modified to achieve compatibility for a.c.-d.c. systems with integrated d.c. links in the a.c. network. This Paper use the MATLAB Software to determine the OPF based Nodal pricing scheme without violating system constraints. This approach has been demonstrated by simulating the study with IEEE30 bus system and conclusions are drawn.

Robotic Fire Extinguishing Vehicle with Rocker Bogie Suspension System

Fire safety is the set of practices intended to reduce the destruction caused by fire. Fire safety measures include those that are intended to prevent ignition of an uncontrolled fire and those that are used to limit the development and effects of a fire after it starts. The robotic fire extinguishing vehicle can be used as a vehicle which can extinguish the fire in a fire hazard zone. The advantage of using this vehicle is that it didn't need the direct presence of the fireman at the fire zone. Instead, this vehicle can be controlled by a user with the help of a laptop. These vehicles can be classified under AGV as the vehicle movements are purely automatic. The rocker-bogie suspension we are using is an another positive factor as this will help the vehicle to move easily over the obstructions in their path. The vehicle can be contained with sensors which help them in detecting the intensity of temperature in the zone and also the PIR sensors used will help them to detect the human presence inside the zone. Special cameras used will help them in having a view of the surroundings through which they move.

Asynchronous Grid Power Transfer Using VFT

Variable frequency transformer (VFT), introduced recently is a flexible asynchronous ac link which is used in power transferal process between asynchronous power system grids. VFT was first installed at Langlois substation, which interconnects the Hydro-Québec (Canada) and New York (USA) systems. The torque of the rotary transformer is externally altered in order to control the direction and magnitude of power transfer. MATLAB Simulink model of VFT is designed, which is used to indicate power transmission between two asynchronous grids and also to control the power flow direction. MATLAB Simulink model of VFT along with its control system is developed and result has been studied thoroughly. Simulation results for different torque and frequency conditions have been discussed. Moving further, power transfer and torque graphical representations are also obtained and results are compared. Thus, the working concept of VFT and its power flow conditions are verified by MATLAB simulation results.
