This paper considers the robust stabilization problem for Takagi-Sugeno fuzzy systems with time-varying delays subject to input saturation. The purpose is the design of dynamic anti-windup fuzzy controllers ensuring convergence of all admissible initial states within the domain of attraction. Delay-dependent conditions for the existence of solutions to this problem are obtained. A simulation ex...

We consider colorful bin packing games in which selfish players control a set of items which are to be packed into a minimum number of unit capacity bins. Each item has one of m ≥ 2 colors and cannot be packed next to an item of the same color. All bins have the same unitary cost which is shared among the items it contains, so that players are interested in selecting a bin of minimum shared cos...

Abstract. Coloring sparse graphs under various restrictions is a theoretical problem of significant practical relevance. Here we consider the problem of maximizing the number of different colors available at the nodes and their neighborhoods, given a predetermined number of colors. In the analytical framework of a tree approximation, solutions obtained by population dynamics show that existing ...

world travel and tourism council has estimated that contribution of tourism sector to global economy and employment will be increasing in the next 10 years. travel and tourism contributes to various areas of economy and tourism is accounted as one of most significant industries of 21st century. if countries provide the required capacity for development of tourism industry, they would be able to...

Nanobubble is a mystery in terms of stability and longevity. Nanobubble, now directly imaged by tapping mode atomic force microscopy or by dynamic light scattering, were previously inferred from long ranged attraction between hydrophobic surfaces immersed in water. They exists in an interconnected, irregular and closed pack structure whose lifetime is in order of hours and whose morphology is d...

Based on previous molecular dynamics simulation results for acetylcholinesterase dimer, we calculate and analyse the electrostatic field fluctuations around the enzyme. The results show that dynamic features of the electrostatic field favor attraction of the positively-charged substrate. An Internet link to an animation of the results is also provided.

Background. In many insects and spider species, females attract males with volatile sex pheromones, but we know surprisingly little about the costs and benefits of female pheromone emission. Here, we test the hypothesis that mate attraction by females is dynamic and strategic in the sense that investment in mate attraction is matched to the needs of the female. We use the orb-web spider Argiope...
