Distributed power generation and cogeneration of heat and power is an attractive way toward a more rational conversion of fossil and bio fuels. Solid oxide fuel cell (SOFC) – gas turbine (GT) hybrid systems are emerging as the most promising candidates ena ...
Some fields such as the Monitoring of Civil Engineering Structures, need very sensitive acceleration and inclination sensors with a high resolution at low accelerations (typically less than 1G) and moderate frequencies (typically less than 20 Hz) or very s ...
In the context of energy storage with supercapacitors, the so called round trip efficiency is an important factor that can be strongly affected by the characteristics or performances of the used converter. This paper presents a dedicated DC-DC converter, w ...

The design of biofuel processes is realised using a computer aided process system design methodology that aim at defining the type and the size of the technologies, the way they are interconnected and the way they are operated for a given socio-economical ...
A device for energy harvesting from an impact by using a piezoelectric MEMS harvester comprising at least a gear (1) driven by an inertial mass system and a piezoelectric transducer (2) located over the gear in order to keep the system as compact as possib ...
This article presents the analysis of the power efficiency of the inductive links used for remote powering of the biomedical implants by considering the effect of the load resistance on the efficiency. The optimum load condition for the inductive links is ...
A new procedure for benchmarking analysis has been developed to evaluate the energy efficiency of a chemical process. Benchmarking is performed to identify process inefficiencies before developing energy enhancement measures. The new procedure combines typ ...
Models for hydrolysis, fermentation and concentration process, production and utilization of biogas as well as lignin gasification are developed to calculate the heat demand of ethanol production process and the amounts of heat and power generated from res ...
Recently, various alternatives to batteries, such as microfabricated fuel cell systems, have been proposed for portable power generation. In large-scale power production plants emphasis is placed on energy conversion efficiency. On the other hand, the intr ...
