Among solar passive systems integrated in buildings, sunspaces or solar greenhouses represent a very interesting solution. A sunspace is a closed, southbound volume, constituted by transparent surfaces, adjacent to a building, which reduces winter energy demand thanks to the use of solar gains. The effect of a typical solar greenhouse on the energy balance of a building was evaluated during the...

This paper offers an approach and a theoretical framework for eliciting emotional speech using actors. The framework is developed by connecting the goal-based model of emotion proposed by Abelson [1], the work of appraisal theorists, and an approach to the actor's technical process widely used in the professional theater and taught in modern conservatories. In doing so, we hope to address some ...

Within a simplified atmospheric model the greenhouse effect is treated by analytical methods starting from physical first principles. The influence of solar radiation, absorption cross sections of the greenhouse molecules, and cloud formation on the earth’s temperature is shown and discussed explicitly by mathematical formulae in contrast to the climate simulations. The application of our analy...

In this paper, mathematical models are presented to study the thermal behavior of crops (cabbage and peas) for open sun drying (natural convection) and inside the greenhouse under both natural and forced convection. The predictions of crop temperature, greenhouse room air temperature and rate of moisture evaporation (crop mass during drying) have been computed in Matlab software on the basis of...

Solar greenhouse, as an intelligent production system, is a trend in the development of facility agriculture. The major crops cultivated in greenhouses are high-value crops such as leafy vegetables, fruit vegetables, and flowering plants. Wireless sensor network (WSN) is a new technology of information acquisition that has been widely used in agriculture, especially in greenhouses. Environmenta...

one of the most main head in governments is to achieve the energy for their countries. as the fossil sources are at their ends and also they cause greenhouse emission and environment pollution, shifting to renewable sources of energy is an indispensable alternative for most countries. the sun is the most important renewable energy source. to assessment reachable solar radiation in mashhad from ...

utilization of fossil fuel for supplying of requires energy of desalination systems is common. on the other hand, solar energy is one of the high-grade energies in the world that can be found specifically in hot weather places. therefore, utilization of solar energy for operation of desalination systems will reduce greenhouse gases and is a good alternative way. common exergy analysis method (s...
