The present work is focused on the control of indoor thermal comfort in buildings equipped with HVAC (Heating, Ventilation and Air Conditioning) systems. The occupants' thermal comfort sensation is addressed here by the well-known comfort index (PMV-Predicted Mean Vote). In this context, different strategies for the control algorithms are proposed by using(More)
Fencamfamine (FCF) is a psychostimulant drug classified as an indirect dopamine agonist. In the present study we evaluated the daily variation in plasma FCF concentration and in striatal dopamine receptors. Adult male Wistar rats (250-300 g) maintained on a 12-h light/12-h dark cycle (lights on at 07:00 h) were used. Rats received FCF (10.0 mg/kg, ip) at(More)
This paper is focused on a mathematical model applied to both building thermal analysis and control systems design. A lumped approach is used to model the room air temperature and a multi-layer model for the building envelope. The capacitance model allows to study the transient analysis of room air temperature when it is submitted to sinusoidal variation of(More)
This paper presents the development of a simulation tool based on the Matlab computational environment for building temperature performance analysis with automatic control. The simulation tool contains mathematical models for buildings, HVAC (Heating, Ventilation and Air Conditioning) systems, sensors, weather data and control algorithms. The building(More)
Orthonormal Basis Functions (OBF) is a structure of dynamic models that have been applied in different classes of dynamic systems. Several works describing the theory and applicability of OBF (Orthonormal Basis Functions) in identification and control can be found in the literature. This work is focused on the problem of finding a(More)
— This paper deals with the problem of finding the pole(s) in Orthonormal Basis Functions (OBF) models. In fact, any stable system can be exactly represented by an infinite orthonormal functions series, assuming that the basis used in such representation is complete. However, in practice a truncated basis functions expansion is used. For certain basis(More)
