Σκοπός της παρούσας διπλωματικής εργασίας είναι, αρχικά, η αριθμητική προσομοίωση του πρότυπου ηλιακού συλλέκτη αέρα που κατασκευάστηκε από το Εργαστήριο Μεταφοράς Ενέργειας και Μάζας του Τμήματος Μηχανικών Μηχανολογίας ...

Upconverting nanoparticles (UCNPs) which present outstanding optical properties can offer new possibilities in fluorescent applications. In comparison with other fluorescence materials like semiconductors and organic ...

A modern form in Adaptive Architecture is the buildings that have the ability to adapt their shape according to certain conditions, in order to achieve better use and better energy efficiency. In the present dissertation ...

In recent years, robots have entered human life, replacing, supplementing or collaborating with humans. As part of this master's thesis, the reader will be informed about the design, construction, assembly and control of ...

Precious Metals (PM), like Palladium and Gold, have gathered great attention in the last few years due to their specific physicochemical properties, including their strong catalytic activity and environmental stability. ...

In the last decades, an enormous interest appears at the scientific community on the magnesium silicide type materials that exhibit remarkable thermoelectric properties. Environmental-friendliness, low cost, excellent ...

Large amounts of energy are released into the environment by modern ships. More precisely, the exhaust gases from internal combustion engines (ICE) on commercial and passenger ships discharge enormous amounts of thermal ...

Photovoltaic (PV) systems exhibit different degradation modes resulting to different performance loss rates (PLR). The degradation modes can be attributed to environmental and internal factors (e.g., temperature, humidity, ...

The overall aim of the project is the design and control of a reconfigurable structure, achieving symmetrical and non-symmetrical forms with minimum actuation requirements. The structure is also required to provide flexibility ...

Material substitution is becoming increasingly popular in the transport sector, since the reduction of emissions is closely linked to the reduction of vehicular weight. In the case of gears, the aim is to reduce the gearbox ...
