Abstract

Concentrated solar power (CSP) plants have invited wide attention in various sunlight-rich regions around the world, including India. Under sponsorship of the Ministry of New and Renewable Energy, Government of India, the Indian Institute of Technology Bombay, Mumbai has conceptualized and carried out the basic engineering design, installation, commissioning and operation of a 1 MW(e) CSP plant in the campus of the National Institute of Solar Energy at Gwalpahari, near Gurgaon, Haryana, India. This is a unique facility integrating two different solar collector fields; direct steam-generating linear Fresnel reflector (LFR) field and conventional heat transfer fluid-based parabolic trough collector (PTC) field. It is a researchcum- demonstration facility intended to enable the development of future cost-effective CSP plants in the country. The design basis, brief description of the power plant, learning experiences during commissioning and operation of the plant, as well as preliminary performance results are presented here. The plant is grid-connected and operational. The preliminary results show low performance due to the lower optical efficiencies of both the collector fields, tracking error, loop imbalance of PTC field, and improper receiver size of LFR field.

Abstract

Ongoing development in nanotechnology and bioinformatics will enable the construction of nanorobot which will work at nano-scale. Nanorobot development has many challenges and limitations such as its control and behavior in different environments. In this proposed work we present DNA nanorobot design, Cancer cell detection methodology and DNA nanorobot control techniques for its movement in dynamic environment are described using Fuzzy Logic (FL) rules. Proposed model will find the cancer cell and try to apply drug to that cell to recover it.

Abstract

The purpose of this note is to examine the long-run demand-potential for electric motors in India. By "long run", we mean a period of five years which is also the time span used hy the Government of India in its planning. The nature of the product and the time dimension involved are such that consumer surveys to forecast the demand potential for motors will be of little avail. Projections of demand trends must be based on the relationships between motor-demand and some meaningful independent variables which can be justified on economic and technical grounds. Because of the relatively long-term nature of the forecast, the focus will be on over-all demand-trends and not on detailed estimates of the demand for different types of motors.

Abstract

A micro level analysis for understanding the major determinants of research productivity of individual scientists in the National Agricultural Research and Education System of India was undertaken. A sample of two hundred scientists was drawn through multistage disproportionate stratified random sampling from a high performing and a low performing agricultural institute in India. Forced choice Q-sort technique was employed to record perception of respondents regarding relative influence exerted by selected variables on their research productivity and a factor analysis using principal component method with varimax rotation helped in extracting 11 major factors determining research productivity of agricultural scientists, namely, organizational research environment, creativity, perseverance and commitment, research facility, ability to work under constraint, incentive policy, proactiveness, purpose-driven orientation, achievement motivation, involvement in teaching and job satisfaction. The apparent uniformity in percentage variance contribution of these 11 factors implies that optimum research productivity of scientists can only be harnessed when personal and organizational factors work in harmony.

Abstract

Numerical integration is a frequently-needed tool in modern Science and Engineering. Engineers and Scientists typically visualize integration as the process of determining the area under a curve. Besides this, because of its many more applications, it is often viewed as a discipline in and of itself. In this paper we develop a mathematical simulator for solving numerical integration problems. This simulator is incorporated with a combination of Trapezoidal rule, Simpson’s 1/3 rule, Simpson’s 3/8 rule and rule.

Keywords

Trapezoidal, Weddle, Syracuse, Language.
