In recent years more and more focus has been placed on the environmental aspects of ships, because of the great attention to exhaust gas emissions from ships including CO2, a leading contributor to Green House Gasses (GHG) emissions, due to their negative effect on global warming. Maritime transport has clear environmental advantages: it expends relatively little energy and its infrastructure r...

UNLABELLED We conducted several aviary experiments to investigate the influence of colours in quantity judgments of two species of birds; house crow (Corvus splendens) and common myna (Acridotheres tristis). Different quantity (in seven different food proportions) of mealworms were presented nonsequentially to all birds using artificially coloured red mealworms, for experiment 1, and using arti...

As it is well known, Monitoring and controlling of green house parameters plays a crucial role for quality production of crops. Different techniques have been developed in past for actual monitoring and controlling of major green house parameters such as temperature, humidity, soil moisture, light intensity and CO2 in atmosphere. Controlling of parameters is done by means of relays. The main ta...

The removal and eventual disposal of adsorbed and absorbed gasses from solid or semi-porous surfaces requires the detachment and diffusion of the gasses. To facilitate the process, the method described here uses the heretofore undescribed product Air Depleted Water (ADW), although the process can be applied to other liquids. By removing the dissolved air gasses, a maximum concentration gradient...

This paper presents the novel control strategy, for green house climate control. Till now, there are many control strategy that is work in India, to control green house environment but they are not adequate for good control performance. The controller used in the present work is conventional proportional, integral and derivative (PID) controllers with adaptive neural network. It provides good a...

In this paper a low voltage, low cost & high efficiency based solar maximum power point tracking system for green house applications is presented. The main controlling element is the micro controller programme in c language in order to extract maximum solar power point. In addition we use buck converter for MPPT. Further this maximum power is utilized to drive pumps and fans of green house.
