STOCHASTIC ELECTROMAGNETIC COMPATIBILITY - INTEGRITY OF CABLES IN COMPLEX STOCHASTIC ENVIRONMENTS
Quantifying the effects of uncertainties on the behavior of electronic systems is nowadays of paramount importance in regards to electromagnetic compatibility (EMC) standards. Knowledge and use of the most efficient techniques of uncertainty propagation is often of practical importance for the analysis and design of systems in the EMC framework. A series of explorative works is being conducted in order to apply the most efficient stochastic methods to reliability assessment and sensitivity analysis of EMC problems under uncertainty.

RELIABILITY-BASED OPTIMIZATION OF ENERGY PERFORMANCE OF BUILDINGS
The performance of building insulations depends on the material properties and thickness and on the efficiency of heating and cooling systems. Performance is subjected to various types of uncertainties which affect insulation and lead to additional costs. The research activities aim at considering the uncertainties related to the materials, climate changes and occupant behavior. A new formulation of the total energy cost is provided and applied to design optimization under reliability constraints, in order to allow for better retrofitting decisions.
