We have exploited the recently obtained complete genome sequence of Kluyveromyces lactis to compare the repertoire of transcriptional regulators between K. lactis and Saccharomyces cerevisiae. Looking for similarities with the S. cerevisiae proteins of this functional class, we observed a reduction in gene number, which is not randomly distributed among the(More)
Transcriptional transactivators are important proteins which in addition to controlling the cell regulatory circuitries, can be manipulated for various biotechnological processes. The latter is of great interest for non-conventional yeasts used for industrial purposes. To facilitate the identification of these transactivators, we have reanalyzed the(More)
This paper presents an advanced driver assistance system (ADAS) for lane keeping, together with an analysis of its performance and stability with respect to variations in driver behavior. The automotive ADAS proposed is designed to share control of the steering wheel with the driver in the best possible way. Its development was derived from an H2-Preview(More)
This paper addresses the disturbance attenuation problem by output feedback for multivariable linear systems with delayed inputs. To solve this problem, a feedback compensator is used, which is decomposed into an observer part, a state predictive part, and a static feedback part. Then, the analysis of the closed loop system is made on an equivalent linear(More)
This paper deals with delay-scheduled control of linear systems with time-varying delays. First, a new model transformation is given which allows to provide a unified approach to stability analysis and state-feedback control synthesis for time-delay systems represented in “linear fractional transformation (LFT)” form. A new type of controller is then(More)
This paper is concerned with the synthesis of delay-scheduled state-feedback controllers which stabilize linear systems with timevarying delays. In this framework, it is assumed that the delay is approximately known in real-time and used in the controller in a scheduling fashion. First, a new model transformation turning a time-delay system into an(More)
