We investigate a one dimensional chain of 2N harmonic oscillators in which neighboring sites have their energies redistributed randomly. The sites −N and N are in contact with thermal reservoirs at different temperature τ− and τ+. Kipnis, Marchioro, and Presutti [18] proved that this model satisfies Fourier’s law and that in the hydrodynamical scaling limit, when N → ∞, the stationary state has...

We calculate structure functions at small x both under the assumption of a hard singularity (essentially, a power behaviour for x → 0), and that of a soft-Pomeron dominated behaviour (also called double scaling limit). A full next to leading order (NLO) analysis is carried for the functions F2, F Glue and the longitudinal one FL in ep scattering, and for xF3 in neutrino scattering. The results ...

This paper presents a new control architecture for fast, accurate force control of antagonistic pairs of shape memory alloy wires. The main components are: a differential-mode controller, which controls the output force, an anti-slack mechanism, a rapid-heating mechanism and an anti-overload mechanism. The closed-loop response is fast and accurate, even in the presence of large external motion ...

We find a new Penrose limit of AdS5 × S5 that gives the maximally symmetric pp-wave background of Type IIB string theory in a coordinate system that has a manifest space-like isometry. This induces a new pp-wave/gauge-theory duality which on the gauge theory side involves a novel scaling limit of N = 4 SYM theory. The new Penrose limit, when applied to AdS5×S/ZM , yields a pp-wave with a space-...

A switched sliding mode control strategy for a class of nonlinear uncertain systems is presented in this paper. It is characterized by an event– driven gain reduction mechanism which relies on a decomposition of the system state into regions. By enforcing sliding mode behaviors on a suitable set of sliding manifolds, while avoiding the generation of limit cycles, the proposed strategy proves to...

The N-System with independent Poisson arrivals and exponential server-dependent service times under first come first served and assign to longest idle server policy has explicit steady state distribution. We scale the arrival and the number of servers simultaneously, and obtain the fluid and central limit approximation for the steady state. This is the first step towards exploring the many serv...

2014 The longitudinal magnetoresistance is calculated in the quantum limit in the case of a point like interaction between electrons and donors. We account for the influence of the bound states on 03C3zz The position and width of donor states are derived, and the effects of collision broadening are discussed.

This paper presents an approach to estimate probabilities of failure in cases where the random variables are correlated. An explicit limit state function is constructed in the uncorrelated standard normal space using the Nataf transformation and a support vector machine (SVM). The method of explicitly constructing the limit state function is referred to as explicit design space decomposition (E...

The assessment of the reliability of concrete structures during fire is becoming increasingly important due to the emergence of performance based design codes, the increased interest in decision making with respect to life time optimization of infrastructure, and the direct applicability of reliability calculations for insurance purposes. Most recent studies on the topic of the probabilistic ca...

Placing column lap-splice in the locations of possible nonlinear deformation may adversely affect the structures response to strong ground motions. Localization of damage in splice zone may change the structural response and prevent the load redistribution and development of a uniform pattern of nonlinear excursions among the various members. Validated by existing laboratory experiments, this s...
