This paper describes the progress of an advanced pulsed plasma thruster (PPT).The PPT currently being developed for flight which represents a significant leap in technology compared to previous flight models. The PPT will be used to extend satellite life from about 1–3 months to over one year by raising it's operational orbit. The PPT is an ideal propulsion system for extending the small satellite life because of it's high specific impulse (>1000 sec), low system wet mass (<5 kg), and inert nature when not powered (thus minimizing shuttle integration issues). In addition to the life enhancement mission, the on-orbit operations have been specifically designed to rigorously test the PPT ant to demonstrate it's compatibility with the satellites spacecraft in order to validate it for commercial satellites.

An eco-friendly inhibitor L-valine (LV) in controlling corrosion of carbon steel in rain water in the absence and presence of Zn2+ has been evaluated by mass loss method. The formulation consisting of 50 ppm of L-valine and 50 ppm of Zn2+ offers good inhibition efficiency of 74%. When 50 ppm of sodium gluconate (SG) is added to the formulations consisting of 50 ppm of LV and 50 ppm of Zn2+, the inhibition efficiency increases from 74% to 98%. As the immersion period increases, the inhibition efficiency does not alter. Polarization study reveals that this formulation functions as a mixed inhibitor. AC impedance spectra reveal the presence of a protective film on the metal surface. The FTIR spectra study lead to the conclusion that the Fe2+ - LV complex and Fe2+ - SG complex formed on anodic sites of the metal surface controlled the anodic reaction and Zn(OH)2 formed on the cathodic sites of the metal surface controlling the cathodic reaction. The Ecofriendly inhibitor L-valine - Zn2+-SG system may find in cooling water system

Optimization of electrical machines is making trade-off between different objectives and is usually done for any one of the parameters, for example, cost, efficiency, torque and starting current associated with the system (i.e., single objective), or with more than one parameter (i.e., multi objective). Optimization process shall include, if any, the constraints imposed in the system. In the recent years, Genetic Algorithm (GA) has been successfully applied to the design optimization of electromagnetic devices and electrical machinery. In this paper, multi - objective design optimization of three phase Induction Motor (IM) is presented considering cost and efficiency as objectives. A design package has been developed for a three phase squirrel cage type IM having specifications: 5 hp, 4 - pole, 400 V, 50 Hz. delta connected. The motor design procedure consists of a system of non - linear equations which evaluates the various parameters associated in the design without violating the constraints imposed. Optimization has been carried out using a direct search method, Hooke and Jeeves method and also using GA. A combination of conventional optimization technique with GA (i.e., results obtained in Hooke and Jeeves method are fed as input data in GA process) has also been carried out. A comparative study and analysis of the end results obtained through computer simulations are presented in the paper.

The daily air temperature measured at few stations in Sutlej basin need to be interpolated spatially across the basin to account for spatial variability in the proposed snowmelt runoff model. GIDS algorithm combines the multiple regression and inverse-distance-squared approaches in which the inputs includes location and elevation details of the stations with reference to inverse squared distance between each station. The model was created in GIS environment and executed daily for April and May by varying the coefficients generated using MATLAB software with 30m resolution. The model contains two modules, with Kaza and Racksham as check stations. Statistical analysis result shows, according to Kaza station the percentage of error is +/− 5%. The standard deviation for both the months is 0.60 and 0.44. In case of Racksham, the percentage of error is within +/− 20%. The standard deviation for both the months is 3.4 and 1.12. Based on analysis, GIDS model was governed by the range of inputs like spatial distance, elevations and temperatures.The computed temperatures were compared with those derived using lapse rate method (LRM). On comparison GIDS produced better results than LRM. Thus the study concludes that GIDS can be used for interpolation with certain boundary conditions.

“Technology does not drive change, it enables change.” The primary purpose of Technology is its implementation in day-to-day life wherein it could enhance the lifestyle as well as provide better safety and performance to its end users. The government has enforced stringent laws against usage of mobile phones while driving a vehicle. Yet, there seems to be a sense of casualness amongst our citizens towards abiding it, coupled with a belief that they can get by easily without ever being caught. This project facilitates the government to take adequate action against those who are violating these laws. An ingenious and innovative technique is required to detect the persons who are not abiding this code of conduct. Due concern must be given for both inebriated as well as cell phone usage while driving. Aegis taciturn is a device used especially for people who cling to mobile phones even while driving and bilk from laws easily. It is used to prevent texting and calling of mobile phones while driving vehicles. Also, it indicates to cops that a person is using his mobile while driving. In case of countries where there is a peccadillo for this kind of pernicious activities it would be an utilitarian device. It receives the mobile frequencies and the received signal is used to trigger the micro-controller with a glowing LED. As a result of this slightest voltage fluctuation cops would be intimated by a message with the vehicle's number plate along with the location of the vehicle with the help of GPS System.

A substantial increase of photovoltaic (PV) power generators installations has taken place in recent years, due to the increasing efficiency of solar cells as well as the improvements of manufacturing technology of solar panels. These generators are both grid-connected and stand-alone applications. The paper concentrates on the operation and modeling of stand-alone power systems with PV power generators, systems with PV array inverter assemblies, operating in the slave-and-master modes. These results demonstrate that simulation is an essential step in the system development process and that PV power generators constitute a valuable energy source. They have the ability to balance the energy and supply good power quality. It is demonstrated that when PV array inverters are operating in the master mode in stand-alone applications, the perform task of controlling the voltage and frequency of the power system

Marine microalgae (ChaetocerosspI) were grown in batch cultures at different nitrogen levels. Marine microalgae were grown at different nitrogen levels (0.5g/L to 1.0g/L) at 26°C in a sterile condition. Algal samples were collected when it reached its stationary phase and analysed for protein, lipid, and carbohydrate and growth rate. Addition of nitrogen source led to an increase in the biomass (from 1 to 2 g/L), protein content (38 to 46 %), carbohydrate (7 – 18 %) and lipid (20 to 45 %). At low nitrogen levels, the Marine microalgae contained a protein (42 %), lipid (55 %) and carbohydrate (11 %). The algae did not show any increase in their biomass, lipid and protein compositions, when the nitrogen concentrations in the nutrient medium was increased above 1.0 gm/L. Thus the Marine microalgae can be grown under increasing nitrogen level to yield high biomass, lipid and protein compositions.
