Tecnologie ad agenti e sistemi embedded

Information technology (IT) is on the verge of another revolution. Driven by the increasing capabilities and ever declining costs of computing and communications devices, IT is being embedded into a growing range of physical devices linked together through networks and will become ever more pervasive as the component technologies become smaller, faster, and cheaper. [..] These networked systems of embedded computers, referred to as EmNets throughout this report, have the potential to change radically the way people interact with their environment by linking together a range of devices and sensors that will allow information to be collected, shared, and processed in unprecedented ways.[..] The use of EmNets throughout society could well dwarf previous milestones in the information revolution.[..] IT will eventually become \textbf{an invisible component of almost everything} in everyone`s surroundings. Con il ridursi dei costi e l'aumentare della capacità di computazione dei componenti elettronici sono proliferate piattaforme che permettono al bambino come all'ingegnere di sviluppare un'idea che trasversalmente taglia il mondo reale e quello virtuale. Una collisione tra due mondi che fino a poco tempo fa era consentita esclusivamente a professionisti. Oggetti che possono acquisire o estendere funzionalità, che ci permettono di estendere la nostra percezione del mondo e di rivalutarne i suoi limiti. Oggetti connessi alla 'rete delle reti' che condividono ed elaborano dati per un nuovo utilizzo delle informazioni. Con questa tesi si vuole andare ad esplorare l'applicazione degli agenti software alle nuove piattaforme dei sistemi embedded e dell'Internet of Things, tecnologie abbastanza mature eppure non ancora esplorate a fondo. Ha senso modellare un sistema embedded con gli agenti?

Sistemi per la climatizzazione mediante pompe di calore geotermiche e pali energetici

We need a large amount of energy to make our homes pleasantly warm in winter and cool in summer. If we also consider the energy losses that occur through roofs, perimeter walls and windows, it would be more appropriate to speak of waste than consumption. The solution would be to build passive houses, i.e. buildings more efficient and environmentally friendly, able to ensure a drastic reduction of electricity and heating bills. Recently, the increase of public awareness about global warming and environmental pollution problems have “finally” opened wide possibility in the field of sustainable construction by encouraging new renewable methods for heating and cooling space. Shallow geothermal allows to exploit the renewable heat reservoir, present in the soil at depths between 15 and 20 m, for air-conditioning of buildings, using a ground source heat pump. This thesis focuses on the design of an air-conditioning system with geothermal heat pump coupled to energy piles, i.e. piles with internal heat exchangers, for a typical Italian-family building, on the basis of a geological-technical report about a plot of Bologna’s plain provided by Geo-Net s.r.l. The study has involved a preliminary static sizing of the piles in order to calculate their length and number, then the project was completed making the energy sizing, where it has been verified if the building energy needs were met with the static solution obtained. Finally the attention was focused on the technical and economical validity compared to a traditional system (cost-benefit analysis) and on the problem of the uncertainty data design and their effects on the operating and initial costs of the system (sensitivity analysis). To evaluate the performance of the thermal system and the potential use of the piles was also used the PILESIM2 software, designed by Dr. Pahud of the SUPSI’s school.
