In the last decade we have witnessed the birth and dramatic growth of mobile devices, from cellular-to smart-phones. Despite the huge amount of information achievable from an always-connected reality, researchers that work in the mobile devices field fight against the impossibility to explore, inspect and test their work on such a vast set of possible environments, use case scenarios, hardware and...
Smart buildings are essential for future smart grids. We propose a general method and algorithms to integrate residential smart buildings with smart grids. Such integration has to deal with the ability for the smart building to forecast its energy consumption, the proposed method is able to learn the building occupants habits and to use such information to forecast the energy consumption. Moreover,...
In the context of mobile devices, the thermal problem is an emerging one, as it affects the user experience and involves factors that are both internal and external with respect to the device. In this paper, we present an evaluation of these factors, that consists of two parts. The first one is the analysis of thermal interactions between the internal components of the system, performed with an infrared...
Smart buildings have been proposed as the solution for the creation of comfortable and energy-efficient living and working spaces. In the last few years, the energy-efficiency aspect is becoming more and more important and for this reason a lot of research effort has focused on the optimization of energy consumption, especially for what concerns commercial buildings, since they contribute to the 70%...
Although the reliability and robustness of the AES protocol have been deeply proved through the years, recent research results and technology advancements are rising serious concerns about its solidity in the (quite near) future. In this context, we are proposing an extension of the AES algorithm in order to support longer encryption keys (thus increasing the security of the algorithm itself). In...
Smart spaces are environments such as apartments, offices, museums, hospitals, schools, malls, university campuses, and outdoor areas that are enabled for the cooperation of objects (e.g., sensors, devices, appliances) and systems that have the capability to self-organize themselves, based on given policies. Since they can be used for an efficient management of the energy consumption of buildings,...
Mobile devices take an important part in everyday life. They are now cheaper and widespread, but still a lot of time is spent by the users to configure them: users adapt to their own device, not vice versa. Can our smart phones do something smarter? In this work, we propose a framework to support the development of context aware applications for Android devices: the goal of such applications is to...
The constantly growing complexity of heterogeneous systems requires effective methods for supporting the designer both during the development of the application and the implementation of the architecture. Unfortunately, existing tools still require that the designer develops large parts by hand, especially when hardware accelerators and partial dynamic reconfiguration are taken into account. This...
The automatic generation of hardware implementations for a given algorithm is generally a difficult task, especially when data dependencies span across multiple iterations such as in iterative stencil loops (ISLs). In this paper, we introduce an automatic design flow to extract parallelism from an ISL algorithm and perform a design space exploration to identify its best FPGA hardware implementation,...
