The selection of an optimal regular-shaped pattern set for very low bit-rate video coding, focusing on moving regions has been the objective of much recent research in order to try and improve bit-rate eficieciency. Selecting the optimal pattern set however, is an NP hard problem. This paper presents a Generic Variable Pattern Selection (GYPS) algorithm. which introduces a pattern selection par...

This article is mainly based on the work [7], and it is dedicated to the 60th anniversary of B. Bonnard, held in Dijon in June 2012. We focus on a controlled Cucker–Smale model in finite dimension. Such dynamics model self-organization and consensus emergence in a group of agents. We explore how it is possible to control this model in order to enforce or facilitate pattern formation or converge...

The target approach to reactor synthesis tries to determine an upper bound for the performance of a chemical reactor network as measured by its objective function (such as yield or reactor volume). This leads to an optimal control formulation in which the residence time distribution and the micromixing function are the control variables. The optimal control problem is solved using a gradient ba...

In this paper, we consider the pattern matching problem in DNA and RNA sequences where either the pattern or the text can be degenerate i.e. contain sets of characters. We present an asymptotically faster algorithm for the above problem that works in O(n logm) time, where n and m is the length of the text and the pattern respectively. We also suggest an efficient implementation of our algorithm...

This paper considers the optimal control problem for the bilinear system based on state feedback. Based on the concept of relative order of the output with respect to the input, first we change a bilinear system to a pseudo linear system model through the coordinate transformation. Then based on the theory of linear quadratic optimal control, the optimal controller is designed by solving the Ri...

There has been a significant volume of recent work on FPGA designs for pattern matching. Although various pattern-matching architectures have been presented, attempts to compare different designs have been inconclusive, or even misleading, due to the lack of a common evaluation framework. In this paper, we present an analytical model of FPGA pattern-matching architectures that quantitatively ex...

This paper provides necessary and sufficient conditions for several forms of controlled system reliability. For comparison purposes, past results on the reliability analysis of controlled systems are reviewed and several of the past results are shown to be either conservative or have exponential complexity. For systems with real and complex uncertainties, conditions for robust reliable stabilit...

In this paper a new excitation control scheme that improves the transient stability of multimachine power systems is proposed. To this end the backstepping technique is used to transform the system to a suitable partially linear form. On this system, a combination of both feedback linearization and adaptive control techniques are used to confront the nonlinearities. As shown in the paper, the r...

This paper presents a solution to the problem of constructing control programs, i.e. sequences of control modes, from a given motion alphabet. In particular, techniques are developed that enable reinforcement learning to act directly at the mode level, and hence make learning applicable to continuous time control systems in a straight-forward manner. Moreover, given such a control program, the ...

In a previous work, we proposed a new binary-light projection mechanism that had a much reduced system size that made it particularly suitable for 3D shape inspection of semiconductor products. The inspection speed of the mechanism was governed by the number of required images which also equaled the number of shiftings of the grating. In this paper we address how inspection speed could be gaine...
