The primary goal of the OPTIMA project is to optimize HVAC systems (heating, ventilation and air conditioning systems) and building structures with respect to energy consumption. Presently the focus is developing an integrated computerized system for simulation purposes. A central data repository defined by a data model provides data persistency. The existing data models developed in ATLAS [1,2...

In this paper we combine oligopoly theory and fishery dynamics to study the effects of imperfect competition and cooperation among the players on the long run evolution of a living resource. A fish population has the capacity for reproduction and growth over time. It might be diminished, however, by the harvesting activities of a sole owner or several individuals. Hence, answers to questions li...

the main purpose of this study is measuring and comparing of peanut harvesting loss in manual and mechanical methods in addition to economic analysis of them. hence, a field was selected in astaneh-ashrafiyeh and divided to three different plots. two plots were applied to measure mechanical harvesting loss and third one was applied for manual harvesting loss. according to test results, the lowe...

Photosystem II (PSII) is responsible for the water oxidation in photosynthesis and it consists of many proteins and pigment-protein complexes in a variable composition, depending on environmental conditions. Sunlight-induced charge separation lies at the basis of the photochemical reactions and it occurs in the reaction center (RC). The RC is located in the PSII core which also contains light-h...

Energy harvesting is increasingly used for powering wireless sensor network nodes. Recently, it has been suggested to combine it with the concept of transient computing whereby the wireless sensor nodes operate without energy storage capabilities. This new combined approach brings benefits, for instance ultra-low power nodes and reduced maintenance, but also raises new challenges, foremost deal...

Corn harvester row alignment is a critical factor to improve harvesting quality and reduce cob drop loss. In this paper, corn automatic system designed with self-propelled combine harvester, incorporating front-end touch mechanism of the cutting table steering control system. stalk lateral deviation from reference during detected by touch-row that serves as an input The consists Hirschmann PLC ...
