The methodology proposed in the paper applies artificial intelligence (AI) techniques to the modeling and control of some climate variables within a greenhouse. The nonlinear physical phenomena governing the dynamics of temperature and humidity in such systems are, in fact, difficult to model and control using traditional techniques. The paper proposes a framework for the development of soft co...
Cut flower production in the Bogotá savanna is one of Colombia’s main export products. Flower mainly carried out greenhouses, as this type system has substantial advantages over crops grown open fields. Protected agriculture provides timely climate management that improves crop yields. The objective work was to build and validate a 3D CFD numerical model understand spatial distribution temperat...
This article discusses the issues of autonomous power supply greenhouse. The types greenhouses and their main microclimate parameters are considered. calculates payback installing solar panels on a greenhouse usual greenhouse, depending its type. As result, it was revealed that installation has advantageous advantages in comparison with traditional mains
This paper describes and validates the HydroCalculator Tool developed by Conservation Strategy Fund. The HydroCalculator Tool allows researchers, policy-makers and citizens to easily assess hydropower feasibility, by calculating traditional financial indicators, such as the levelized cost of energy, as well as greenhouse gas emissions and the economic net present value including emissions costs...
Little is known about management practices that can simultaneously improve soil and environmental quality and sustain crop yields. The effects of novel and traditional management practices that included a combination of tillage, crop rotation, and N fertilization on soil C and N, global warming potential (GWP), greenhouse gas intensity (GHGI), and malt barley (Hordeum vulgarie L.) yield and qua...
Nowadays, various training systems are utilized to grow greenhouse roses. Some of the training systems permit high canopy light penetration and hence increase canopy photosynthesis rate. The aim of this investigation was to evaluate the response of arching and traditional training systems to shading (0 (no shading/control), 25, 50 and 65%) and their effects on marketing quality of cut roses (...
Freight transport has undesirable effects on the environment. The most prominent of these is greenhouse gas emissions. Intermodal freight transport, where freight is shipped from origin to destination by a sequence of at least two transportation modes, offers the possibility of shifting freight (either partially or in full) from one mode to another in the hope of reducing the greenhouse emissio...
