As traditional organic fuel resources are being depleted in the modern world, energy crisis and environmental situation aggravate and the attention of the mankind is increasingly drawn towards untraditional, renewable sources of energy and opportunities of their efficient use. Georgia has significant geothermal resources concentrated in numerous thermal springs and basins. There are two main basins of thermal waters in Georgia. The water in the Kolkheti basin is distinguished for its low mineralization, it is over...

This paper highlights several aspects regarding energetic and functional advantages of hydraulic transmissions based on adjustable volumetric machines, located in their primary and secondary sectors. To this end, numerical simulations were performed upon hypothetic hydraulic transmissions of primary or secondary adjustment, as well as numerical simulations and experimental research on MOOG radial piston pump type RKP-D. This servo pump, which can operate either in closed loop of flow or in closed loop of pressure,...

In this study, simulation modelling of insulation layer (di), for residential buildings in 81 cities classified into four climatic regions in Turkey was. This stimulus model is constructed into Rule-Based Mamdani-Type Fuzzy Modelling (RBMTF) using input parameters (Uw, Te,Met, Te,TSE, Rwt, qTSE) and output parameter di described by RBMTF if-then rules. RBMTF has been designed using the MATLAB fuzzy logic toolbox.

The paper presents a hydraulic system used for the recovery kinetic energy from the road motor vehicle in the braking phases and using it, in the acceleration phases, in order to energy saving of the motor vehicles. All the system is conceived like a mechatronics system, for the medium and heavy motor vehicles. The hydraulic system allows the extrapolation to different sizes of vehicles and can be mounted on new motor vehicles, as well as old cars, in the framework of rehabilitation actions. The energy recovery hy...
