This paper presents a comprehensive analysis of voltage step-up converters for energy harvesting and other low-power applications. The step-up operation is based on isolating the charge of a mechanically variable capacitor and varying the gap between the electrodes by an appropriate method of providing an actuation force i.e. electrostatic or physical. Two devices are presented; a bi-stable device and a resonant device, specifically designed for solar and vibration energy harvesting respectively. The bi-stable device introduces a separate electrostatic actuator element to manipulate the variable capacitor electrodes, whereas, in the case of the resonant device, ambient vibrations provide the necessary actuation force. System-level Multisim models have been developed and verified using 3D FEM Coventorware and MEMS+ simulations. The devices were then fabricated using a dicing-free Silicon-on-Insulator (SOI) process developed at the Southampton Nanofabrication Centre. [less ▲]

The limited semantics of thesauri and similar knowledge models hinder the searching and browsing possibilities of the bibliographic databases classified with this type of resources. This work proposes an automatic process to convert a knowledge model into a domain ontology through the alignment with DOLCE, an upper level ontology. This process is facilitated by an intermediary alignment with Wordnet, a lexical model. The process has been tested with the thesauri and bibliographic databases of Urbamet and the European Urban Knowledge Network. The Urbamet model has been used to create an atlas of urban related resources with advanced search capabilities. [less ▲]

The world is facing a historical increase in energy demand and energy consumption. As consequence the conventional fossil fuels are depleting faster with an inherent pollution causing sever damages to our environment. Renewable energy sources are considered as a solution to both environmental issue and energy demand. At the same time a lot of waste heat is witnessed in processes in industries and other thermal devices such internal combustion engines. Our objective is to propose a solution to recover this heat wasted. The organic Rankine cycle appeared to us as a solution. This paper presents a study carried out on a prototype of small scale organic Rankine cycle (ORC) driven by two waste heat hot air streams. The prototype was designed using a diaphragm pump, a set of plate heat exchangers and an oil-free scroll compressor adapted to run in expander mode. The available literature on Organic Rankine Cycles only proposes theoretical studies of fluid selection for a given application. This study aims at comparing fluids experimentally. Therefore, several fluids (including R245fa and R123) were tested in the prototype and the performance was measured. The tests were performed to study the performance of the ORC system and the expander over a wide range of working conditions. The temperature of the heat sources varied between 150°C and 200°C. The maximum expander shaft power was above 2kW and maximum expander efficiency was 70%. These tests allowed to point out the critical characteristics that should be taken into account while selecting the components for the design of an ORC. [less ▲]

The current paper describes the design and fabrication of a micromachined electrostatically suspended gyroscope. Electrostatic levitation is employed to suspend the rotor, eliminating the mechanical bearing and thus friction effects between the rotor and the substrate, hence improving long-term stability. The rate of rotation can be measured by detecting the torque-induced displacement of the spinning rotor using capacitive interface circuits. The device structure and its basic operating principle are described, as well as theoretical background and design considerations. The fabrication process of the gyroscope relies on glass/silicon/ glass stack bonding and deep dry etching and is outlined in detail. Initial prototypes realized with this fabrication process are presented and described. [less ▲]
