Mathematical modeling for greenhouse heating by using thermal curtain and geothermal energy
(2004)A thermal model has been developed for the heating of a greenhouse by using inner thermal curtain and natural flow of geothermal warm water through the polyethylene tube laid on its floor. The calculations were done for a ... 
A method for digital grovernor analysis
(Elsevier Science, 1996)The use of digital devices for normal operation and control in the electric utility industry is increasing at a fast pace. By nature, the operation of these devices is discrete and so continuous system analytical techniques ... 
Modeling and comparative thermal performance of ground air collector and earth air heat exchanger for heating of greenhouse
(2005)The potential of using the stored thermal energy of ground for space heating has been investigated with the help of two buried pipe systems, i.e., ground air collector and earth air heat exchanger, integrated with the ... 
Modeling and experimental validation of a greenhouse with evaporative cooling by moving water film over external shade cloth
(2003)A mathematical model through flowing water film on shade cloth, stretched over the roofs and south wall of an even span greenhouse has been developed to study the effectiveness of cooling in greenhouse. The model was ... 
Modeling and optimal design of evaporative cooling system in controlled environment greenhouse
(2002)This communication deals with the development of a mathematical model for experimental validation of the thermal behavior in the greenhouse after evaporative cooling. Extensive experiments have been performed during July ... 
Modeling and optimal design of ground air collector for heating in controlled environment greenhouse
(2003)A mathematical model is devised to study the thermal behavior of a greenhouse while heating with a ground air collector (GAC). A computer program based on MatLab software has been used to predict the plant and room ... 
Modeling of energy distribution inside greenhouse using concept of solar fraction with and without reflecting surface on north wall
(2005)A considerable portion of the solar radiation falling on transparent north wall/roof inside an east–westoriented greenhouse is lost due to lowaltitude angle of sun during winter months. Replacing the transparent north ... 
Modified kortewegde vries solitons in an inhomogeneous plasma with negative ions
(1997)The variable coefficient modified Kortewegde Vries (mKdV) equation is derived and solved in an inhomogeneous negative ion plasma considering the plasma density and the ion drift to be spatially varying. The amplitude of ... 
Monthly performance of passive and active solar stills for different Indian climatic conditions
(2004)The monthly performance of passive and active solar stills for different Indian climatic conditions was evaluated. Numerical computations were carried out for hourly variations of average insolation at the Chennai, Jodhpur, ...
