Structural stability issues in planar solid oxide fuel cells arise from the mismatch between the coefficients of thermal expansion of the components. The stress state at operating temperature is the superposition of several contributions, which differ depe ...
A predictive optimal control system for micro-cogeneration in domestic applications has been developed. This system aims at integrating stochastic inhabitant behavior and meteorological conditions as well as modeling imprecisions, while defining operation s ...

The storage of 'cold' with ice slurries-a special type of thermally multi-functional fluids or phase change slurries (PCS)-is discussed. At first an example of a calculation of a thermal energy storage tank in an ice slurry system with a peak load demand i ...
Structural stability issues in planar solid oxide fuel cells (SOFC) arise from the mismatch between the coefficients of thermal expansion (CTE) of the components. The stress state at operating temperature is the superposition of several contributions, whic ...
In this paper, the liner concept is an electroacoustic transducer which acoustic impedance can be changed by electrical means, be it passive or active. Among the different ways to obtain variable acoustic properties on an electroacoustic transducer's voici ...
While most current building simulation tools consider occupants as predictable robots the true nature of human behaviour is more complex. This article describes a set of stochastic models aimed at capturing this complexity by decoupling occupant presence f ...
Private financing and operations of public infrastructures – often also called Public-Private Partnerships or PPPs – are becoming increasingly important, especially in the case of developing countries. Different types of PPP instruments – among which in pa ...
To be profitable, a geothermal energy system must effectively and economically convert a given resource into useful energy services to be delivered to the consumer during different periods of the year. These services include electricity, district heating, ...
In the present context of finding ways to decrease CO2 emissions linked with human activity, district energy systems including polygeneration energy conversion technologies are likely to play a major role. District energy systems meet the heating, hot wate ...
Proton exchange membrane (PEM) fuel cells show characteristics of high power density, low operating temperature, and fast start-up capability, which make them potentially suitable to replace conventional power sources (e.g., internal combustion engines) as ...
