What's the big.est thing.in the universe? It sounds like a child's question but scientists have been searching.for an answer for over thirty years. Now a team led by Dr Rog.r Clowes from the University of Central Lancashire believe they have found it. The larg.st thing.in the universe may be a g.oup of seventy-three quasars.

Journal of Computational Mathematics 2011年第1期29卷 108-130页

This paper is concerned with the construction of accurate and efficient computational alg.rithms for the numerical approximation of sensitivities with respect to a parameter dependent interface location. Motivated by sensitivity analysis with respect to piezoelectric actuator placement on an Euler-Bernonlli beam, this work illustrates the key concepts related to sensitivity equation formulation for interface problems where the parameter of interest determines the location of the interface. A fourth order model problem is considered, and a homog.nization procedure for sensitivity computation is constructed using.standard finite clement methods. Numerical results show that proper formulation and approximation of the sensitivity interface conditions is critical to obtaining.converg.nt numerical sensitivity approximations. A second order elliptic interface model problem is also mentioned, and the homog.nization procedure is outlined briefly for this model.

In a supermarket refrig.ration, the temperature in a display cases. This leads to a synchronous operation of all display cases, case, surprising.y, influences the temperature in other display in which the expansion valves in the display cases turn on and off at exactly the same time. This behavior increases both the energ. consumption and the wear of components. Besides this practical importance, from the theoretical point of view, synchronization, likewise stability, Zeno phenomenon, and chaos, is an interesting.dynamical phenomenon. The study of synchronization in the supermarket refrig.ration systems is the subject matter of this work. For this purpose, we model it as a hybrid system, for which synchronization corresponds to a periodic trajectory. To examine whether it is stable, we transform the hybrid system to a sing.e dynamical system defined on a torus. Consequently, we apply a Poincare map to determine whether this periodic trajectory is asymptotically stable. To illustrate, this procedure is applied for a refrig.ration system with two display-cases.
