This paper presents a new approach of the Design and simulation of a photovoltaic cell using decrement resistance algorithm for maximum power point tracking (MPPT). The Simulation is done in the MATLAB. The algorithm detects the maximum power point of the photovoltaic (PV) cell. It includes module BP SX 150S for a solar photovoltaic. This module provides a maximum power of 150 W. The current-voltage (I-V)&power-voltage (P-V) characteristics are obtained for various values of solar irradiance keeping the cell temperature constant. The points indicating module voltage Vmp and current Imp at maximum Power Pmax are obtained.Keywords

The Electrical power quality issue has attained considerable attention in last decade due to large penetration of power electronics based loads and microprocessor based controlled loads. Power quality has become an important topic of discussion and research, especially in a deregulated environment. As per IEEE 519 std. these parameters of power quality measurement are four in number, of which Total Harmonic Distortion is most widely used. The power quality disturbances decrease the efficiency of power system equipments such as generators. Therefore the issue of power quality is important to both the consumers and the utility of electric power. There are many facets of power quality disturbances and each has its own source and mitigation techniques. The power system faults are important source of power quality disturbances. This paper deals with power quality improvement in four bus system during faulty conditions using double tuned filter to reduce the effects of disturbances on the generators. The four bus system having two load and two generator buses is modeled in MATLAB/Simulink environment. A fault is created near the load bus and power quality disturbances are detected near the generator bus and improved using double tuned filter near the generator bus under study. The Matlab results show the performance of double tuned filter in improvement of power quality disturbances during faulty conditions.

The process of finalization of configuration of a spacecraft starts with 3D CAD definition of Mechanical/Optical/RF axes of various components, subassemblies, and major assemblies. After finalization of the 3D CAD definition the same is sent for the fabrication. Once the fabrication is over, the critical geometries and parameters of each component are measured using the different contact and non-contact methods before the same is assembled to the spacecraft main assembly. The measurement of the geometries of the subsystem and their relative orientation with respect to the spacecraft main assembly is a challenging task. The alignment of the subsystems with respect to the spacecraft main assembly includes the measurement of six transformation parameters and correcting the deltas between the theoretical CAD model and the measured assembly. The evolving technology of intelligent cameras with automated photogrammetric measurements & use of computational metrology has recently begun to play a prominent role in enhancing the productivity and meet the accuracy requirements.
An attempt is made to use the close range photogrammetry system with digital intelligent camera and various optical metrology techniques for spacecraft applications right from the fabrication stages of components to the final spacecraft main assembly. This paper provides the details of the work carried out to check the feasibility of implementation of photogrammetry technique for spacecraft integration. The paper further provides a brief on recent advancements in the optical and digital metrology techniques as well as their advantages/limitations over the existing conventional metrology techniques within ISRO.

In this study effects of different water proofers on compressive strength of cement concrete has been made using experiments. Total 108 cubes were cast using normal, 60% of 20 mm and 40% of 10 mm size of coarse aggregates having three water proofer Dr. fixit, Roff, Aqua Roff proportion of 4ml/kg cement. NDT of the cast cubes using rebound hammer and UPV have been also carried out. All the cubes were tested for ultimate load using compression testing machine and compressive strengths of the cubes are calculated. Based on these data, comparative studies have been carried out to quantify the effect of different water proofers on the compressive strength of the concrete. From these data, salient conclusions are drawn.Keywords
