1. HYBRID SYSTEM SIMULATION TO SUPPLY HEATED AIR TO A SOLAR FOOD DRYER
ABSTRACT The intermittence of solar radiation, due to continuous rainy or cloudy days, is a limitation of simple and small solar dryers. These conditions often make them impossible to use. By including storage systems (thermal accumulation) and/or auxiliary energy sources, drying processes or dehydration can be conducted continuously, even during periods of

2. Technical and economic viability of the installation of a hybrid solar-wind generation system in a Brazilian industry
Abstract The demand for electricity is growing worldwide. At the same time, the non-renewable natural resources that account for a large proportion of the global energy matrix are rapidly depleting, which will pose a major challenge in the near future. Therefore, micro-grid models that use renewable energy sources, such as solar and wind, are rapidly develo

11. Análise sob restrições baseada em um raciocínio energético para o problema de escalonamento tempo real de sistemas de gerenciamento de workflow
This work propose a method of analysis under constraints applied to the problem of real time scheduling in workflow management systems. The goal is to filter the start of activities in order to eliminate inconsistent dates with scheduling solutions and to identify inadmissible schedules due to the inability of energy resources involved. The adopted model is
