The present work is aimed to find a new and efficient type of antioxidants for polypropylene. Hence, effects of 3,3-bis(4-hydroxy-2-methyl-5-propan-2-ylphenyl)-2-benzofuran-1-one, generally known as thymolphthalein, on thermo-oxidative stability of polypropylene in solid and melt states were evaluated and compared with those of SONGNOX 1010, an efficient commercially used antioxidant for the po...

Image sequence stabilization aims to remove unwanted fluctuations from an image sequence. This paper proposes a novel stabilization system making use of a fuzzy filter constructed by dynamic system based estimator definition with a fuzzy corrector. The stabilization system selectively switches between a pre-defined set of membership functions so as to improve gross movement tracking and stabili...

We consider the problem of simultaneous nite gain L p-stabilization and internal stabilization of linear systems subject to input saturation via linear static state feedback. We show that bounded input nite-gain L p-stabilization and local asymptotic stabilization can always be achieved simultaneously no matter where the poles of the open loop system are, and the locations of these poles play a...

This paper focuses on the quadratic stabilization problem for a class of uncertain impulsive switched systems. The uncertainty is assumed to be norm-bounded and enters both the state and the input matrices. Based on the Lyapunov methods, some results on robust stabilization and quadratic stabilization for the impulsive switched system are obtained. A stabilizing state feedback control law reali...

We discuss the mutual coupling of solitary waves of two di$erent types, dark and bright, due to nonlinear interaction between the modes with different signs of group-velocity dispersions, and find a novel class of vector solitons. We investigate the stability of these dark-bright solitons and reveal an important mechanism of soliton stabilization. PALS: 03.40.Kf; 42.50.Rh

Herman’s self-stabilisation algorithm allows a ring of N processors having any odd number of tokens to reach a stable state where exactly one token remains. McIver and Morgan conjecture that the expected time taken for stabilisation is maximised when there are three equally-spaced tokens. We prove exact results on a related cost function, and obtain a bound on expected time which is very close ...

This paper presents a methodology for a synchronous non-reactive distributed system on a tree topology to stabilize from a k-faulty configuration in a time independent of the size n of the system. In the proposed methodology, processes first measure and compare the sizes of the faulty regions, and then use this information to schedule actions in such a way that the size of the faulty regions pr...

Graphene is the newest member of the carbon family, and has revolutionized materials science especially in the field of polymer nanocomposites. However, agglomeration and uniform dispersion remains an Achilles' heel (even an elephant in the room), hampering the optimization of this material for practical applications. Chemical functionalization of graphene can overcome these hurdles but is ofte...

This paper studies the institutional design of the coordination of macroeconomic stabilization policies within a monetary union in the framework of linear quadratic differential games. A central role in the analysis plays the partitioned game approach of the endogenous coalition formation literature. The specific policy recommendations in the EMU context depend on the particular characteristics...

A snap-stabilizing protocol, starting from any arbitrary initial configuration, always behaves according to its specification. In [10], Cournier and al. present the first snap-stabilizing Propagation of Information with Feedback (PIF) protocol in arbitrary networks. But, in order to achieve the desirable property of snap-stabilization, the algorithm needs the knowledge of the exact size of the ...
