A numerical model to predict energy conservation potential of earth-air heat exchanger system and passive thermal performance of building has been developed. This model improves upon previous studies by incorporating effects of ground temperature gradient, surface conditions, moisture content...

A novel passive space conditioning configuration is presented, integrating a Solar Collector System, Underground Storage Tank and Novel Heat Exchanger. This Underground Solar Thermal Heat Exchanger (USTHE) provided improved sensible heating/cooling of air by employing a Novel Heat Exchanger...

In the age of globalization, it has become very important to find out the economic and non-variables which are significantly responsible for volatility in stock markets. Investors have become largely sensitive to these factors which results in change their investment strategy at the time of...

Advancement in genetic algorithm (GA) optimization tools for design applications, coupled with techniques of soft computing, have led to new possibilities in the way computers interact with the optimization process. In this paper, the concept of goal-oriented GA has been used to design a tool...

This article investigates the presence of conditional heteroskedasticity in time series of US stock market returns, and the asymmetric effect of good and bad news on volatility. Further, the study also analyzes the relationship between stock returns and conditional volatility, and standard...

This article investigates the asymmetric nature of US stock market return and effect of heteroskedasticity on stock return volatility. Further, this study also analyzes the relationship between stock returns and conditional volatility, and standard residuals. The monthly opening and closing...

Integrated photovoltaic–thermal solar collectors have become of great interest in the solar thermal and photovoltaic (PV) research communities. Solar thermal systems and solar PV systems have each advanced markedly, and combining the two technologies provides the opportunity for increased...

In this article, we use the concept of artificial neural network and goal oriented design to propose a computer design tool that can help the designer to evaluate any aspect of earth-to-air heat exchanger and behavior of the final configuration. The present study focuses mostly on those aspects...

This paper presents transient analysis of an evacuated tubular solar collector. Basic energy balance equations for the glass envelope, the absorber and the fluid are solved using the finite difference technique to predict the various component temperatures as a function of time. Four versions of...

This is the first part of a set of two papers, about the estimation of solar irradiance on the absorber plate and cover of a semi-cylindrical solar tunnel dryer (STD). The second part discusses the modelling and thermal performance results of the STD. A detailed analysis has been carried out in...
