Decentralized power generation and cogeneration of heat and power is an attractive way toward a more rational conversion of fossil or bio fuel. In small scale power production fuel cell – gas turbine hybrid cycles are an emerging candidate to reach higher ...
A storage supercapacitor subsystem is studied for insertion in a series hybrid electric vehicle (Fig. 1). This subsystem is composed of a supercapacitor bank and a braking resistor used when the supercapacitor voltage is at its maximum value. Generally, wh ...
So far in the Twenty-first century the field of people transportation has had numerous setbacks, of these some are related to air pollution and some to the rarefaction of petroleum sources. Studies have been undertaken within this domain for many years now ...
We study the problem of personalized, interactive tag recommendation for Flickr: While a user enters/selects new tags for a particular picture, the system suggests related tags to her, based on the tags that she or other people have used in the past along ...

Electric vehicles are mainly fed directly from batteries, where the high power solicitation represents a well-known problem with its relation to efficiency and life cycle of batteries. The paper presents experimentation and study of a solution with power a ...
The main problem with Hybrid Electric Vehicles (HEV) is the management of batteries. We suggest to replace the batteries by an energy storage ystem made of supercapacitors on a series HEV with two traction drive. A maximum Control Structure (MCS) of such a ...
The simulation of a series HEV (hybrid electric vehicle) is suggested by using the Energetic Macroscopic Representation (EMR). Simplified models are used in a first step. They lead to the simulation of an overall HEV with its control. The system is decompo ...
In the attempts to attain greater efficiency of mobility, based in the long-term on renewable energy sources, the efficiency of energy conversion in the vehicle remains an important issue. Polymer electrolyte membrane fuel cell technology has the potential ...
A new methodology is presented, based on energy-flow analysis on systems. The aim is to obtain a representation of energy flows between the various sources of a complex system, via energy storage devices connected together with electrical and mechanical co ...
Vehicle drivetrains are complex integrated systems, which need to be designed for numerous thermodynamic, economic and environmental factors. As part of a project of the Alliance for Global Sustainability between the MIT, the SFITs and the University of To ...
