As the range of applications for fiber-reinforced polymer (FRP) composite materials in civil engineering constantly increases, there is more and more concern with regard to their performance in critical environments. The fire behavior of composite material ...
The invention relates to a process for increasing the melt viscosities of polyester resins. This process comprises a step of heating the polyester resin in the temperature range comprised between the melting temperature of the polyester resin and the degra ...
In the context of sustainable development, building insulation represents a major concern as a means of increasing energy efficiency. In order to comply with new norms such as the Passive House standard, locations where load-bearing components must penetra ...
In this communication, we report on the integration of metal-oxide gas sensors on polymeric micro-hotplates made on polyimide and silicon substrates. Low-power consumption micro-hotplates with platinum electrodes and heaters were fabricated on polyimide me ...
We address vehicle classification and mensuration problems using acoustic and video sensors. In this paper, we show how to estimate a vehicle's speed, width, and length by jointly estimating its acoustic wave-pattern using a single passive acoustic sensor ...
Rankine cycles for low to medium power and low temperature heat using water as working fluid, were almost written off. The main arguments speaking against them are reviewed in this paper and the conceptual design of the equipment entirely revisited. An adv ...
We consider the rate-distortion problem for sensing the continuous space-time physical temperature in a circular ring on which a heat source is applied over space and time, and which is allowed to cool by radiation or convection. The heat source is modelle ...

We have performed thermal measurements and electrothermal simulations (finite element modelling) with the aim of optimizing the power consumption and the temperature distribution of micro-hotplates for gas-sensing applications. A silicon island was added u ...
A review, with 17 refs., on research carried out by the polymer reaction engineering group at EPFL in reaction engineering, including kinetic modeling of polymn. reactions (lab. and pilot scale reactors), free radical, polyepoxydation, polycondensation. De ...
