Traffic surveillance plays an important role in computer vision and intelligent transportation systems. However most of the methods concentrate on the day time traffic monitoring. This paper gets a night time traffic surveillance image as its input. The night time traffic surveillance system consists of headlight detection, headlight tracking and pairing, and camera calibration and vehicle speed estimation. First, the headlight detection is done by extracting two features reflection intensity map and reflection suppressed map based on the analysis of light attenuation model. Second, the headlight is tacked and paired using yet effective bidirectional reasoning algorithm. Finally, the trajectory of vehicles headlight is employed to calibrate the surveillance camera and computes the vehicle’s speed. The proposed method can robustly detect and pair the vehicles headlight in night scene and the speed of the vehicle can also be calibrated. © Research India Publications.

This paper analyses the stress distribution over a modern passenger aircraft wing section due to vibrations. A subsonic passenger aircraft as a reference flight and analyzed using FEA optimization tool (ANSYS WORKBENCH).Due to high speed the maximum lift force will be produced over the wing surface. Hence due to this lift force and g-forces the aircraft wing will start to vibrate this will reduce the stability of an aircraft. The boundary conditions are taken from the passenger aircraft survey reports including maximum lift force distribution over the wing section is calculated. © Research India Publications.

The objective of this project is optimization of convergent-divergent geometry and exhaust free jet interaction with ambient air. In this project the simulations have been carried out using the commercial CFD software – CFX. The model geometry and meshing was carried out using ICEM CFD. Free jets are encountered in a variety of industrial applications and in nature. Examples include aircraft gas turbine engines, liquid and solid rocket motors, smoke stacks, cooling towers, and volcanoes. In this experiment, you will study a free air jet issuing from a tube into the air in a nominally quiescent room. You will measure dynamic pressure at various locations in the flow using a Pitot tube and manometer. From the dynamic pressure, you will determine the kinetic energy per unit volume, and hence the local speed. You will observe that as fluid exits the nozzle, it slows down due to shear interaction with the surrounding fluid. Shear interaction also decreases the jet’s kinetic energy, which is ultimately dissipated as heat. Calculations will show that the jet entrains surrounding fluid, and the mass flow rate of the jet increases. © Research India Publications.

The main objective of Load Frequency Control (LFC) is to regulate the power output of electric generator within an area, in response to the changes in system frequency and tie-line loading. Thus, LFC helps in maintaining the scheduled system frequency and tie-line power interchange with other areas within the prescribed limits. Most LFCs are primarily composed of a PID controller. The PID gain is set to a level that compromises between fast transient recovery and low overshoot in the dynamic response of the overall system. This type of controller is slow and does not allow the controller designer to consider the possible changes in operating condition and non-linearity in the generator unit. Moreover, it lacks in robustness. FACTS are designed to overcome the limitations of present non-reheat thermal-thermal power systems and enhance the power system stability. One of the promising FACTS devices is the Thyristor controlled phase shifter (TCPS) to alleviate this difficulty. TCPS is connected in the tie-line to self-tune the parameters of PID controller using Artificial Neural network(ANN) Training based controller. Two area system, have been considered for simulation of the proposed TCPS connected PID controller.The performance of TCPS connected PID and ANN controller have been Compared through MATLAB Simulation..The qualitative and quantitative comparisons have been carried out for PID and ANN Controllers with TCPS shows that in terms of settling Time, peak overshoot and steady state error are greatly improved than that of without TCPS. © Research India Publications.

The objective of this paper is to determine the effect of adding attachments to the tensile strength of conventional hybrid joint. To carry out the experimental study, conventional hybrid and hybrid joints with curved attachments of three different angles (120,160,240) are designed, fabricated and tested using Universal Testing Machine(UTE40) which has the maximum capacity of 600kN until the catastrophic failure of the joints. From the results obtained, tensile strength and failure modes are compared to find the better joint configuration. On comparison, it is clear that 16 degree curved attachment’s strength is more and the load transfer to the bolt is much effective. The above joint has 117% higher strength than the conventional joints. © Research India Publications.
