An implicit Lyapunov-based approach is proposed for generating trajectories of a finite dimensional controlled quantum system. The main difficulty comes from the fact that we consider the degenerate case where the linearized control system around the target state is not controllable. The controlled Lyapunov function is defined by an implicit equation and its existence is shown by a fix point th...

The development of tunable filters is a key point for the ability of optical telecommunication networks to comply with the continuous evolution of the service providers needs. Among the numerous technologies which can be used to achieve narrow bandpass filtering devices, we concentrate our analysis on Thin-Film Interference Coatings and compare the principles, performances and use constraints o...

“Dynamic projection mapping” is a variation of the best-known “projection mapping”. It considers the perceptual analysis of the urban landscape in which the video projection and the observer’s displacement speed are hypothesized. This latter, in particular, is variable and may depend on factors not directly controllable by the driver (slowdowns due to accidents, rallies, etc.). This speed can b...

This paper deals with the complete controllability of semilinear stochastic systems with delay in both state and control under the assumption that the corresponding linear system is completely controllable. The control function for this system is suitably constructed by using the controllability operator. With this control function, the sufficient conditions for the complete controllability of ...

ABSTRACT. In order to describe various real-world problems in physical and engineering sciences that are subject to abrupt changes at certain instants during the evolution process, impulsive differential equations has been used to describe the system model. In this article, the problem of approximate controllability for nonlinear impulsive neutral differential inclusions with nonlocal condition...

The improved Boussinesq equation is studied in this paper. Control properties for this equation posed on a bounded interval are first considered. When the control acts through the Dirichlet boundary condition the linearized system is proved to be approximately but not spectrally controllable. In a second part, the equation is posed on the one-dimensional torus and distributed moving controls ar...

As the result of the broken-up value chain of the world, design becomes an independent commodity. Goods often are designed in one company and produced in another company. Although product is shaped in manufacturing companies of supply chain, design quality is the key sticking-point for product quality. Therefore, finished goods quality lies on the quality of Design-Manufacturing Chain. This pap...

Having access to accurate position information is a key requirement for many wireless sensor network applications. We present SpiderBat, an ultrasound-based ranging platform for wireless sensor networks. It is designed to extend existing node platforms with ultrasound ranging capabilities. SpiderBat features four pairs of independently controllable ultrasound transmitters and receivers, which p...

Type Ia Supernovae hold great promise to measure the cosmic deceleration. The diversity observed among these explosions, however , complicates their ability to measure cosmological parameters considerably. The comparison of near and distant objects depends critically on the global properties of the samples. Systematic errors are introduced in cases where the samples are not compatible. Our disc...

A simple and efficient method for in vitro mutagenesis and recombination of polynucleotide sequences is reported. The method involves priming template polynucleotide(s) with random-sequence primers and extending to generate a pool of short DNA fragments which contain a controllable level of point mutations. The fragments are reassembled during cycles of denaturation, annealing and further enzym...
