Abs-t-We study the problem of running full binary tree based algorithms on a hypercube with faulty nodes. The key to this problem is to devise a method for embedding a full binary tree into the faulty hypercube. Based on a novel embedding strategy, we present two results for embedding an (n-1)-tree (a full binary tree with 2"-l-1 nodes) into an n-cube (a hypercube with 2" nodes) with unit dilat...

We present a method which extends the range of applicability of the domain decomposition approach to tunneling transport. Thereby we gain the ability to simulate e.g. structures with geometrically confined semiconductor quantum dots surrounded by very thin layers of dielectric or quantum dots that are defined through a combination of electrostatic forces and geometric confinement. Recently, exp...

Gyrokinetic particle-in-cell simulation on a transport and microinstability time scale is performed with the ELMFIRE code for a small tokamak FT-2 with kinetic electrons. Turbulent modes are characterized based on their poloidal phase velocity, and tentative comparison with the Doppler reflectometric measurement is done for the poloidal mode rotation. Cyclone base case comparison with adiabatic...

Parametric design optimization of an automotive body crashworthiness improvement is presented. The thicknesses of parts are employed as design variables for optimization whose objective is to increase the maximum deceleration value of the vehicle center of gravity during an impact. Using the Taguchi method, this study analyzes the optimum conditions for design objectives and the impact factors ...

UNLABELLED Over the past decade, medical simulation has developed to a point where it now is poised to become ubiquitous in teaching curricula. Despite this experience, there is little up-to-date information to help new instructors and operators learn the general principles of simulation. The purpose of this article is to provide prospective simulation instructors with basic concepts and a prac...

Change of globe surface height is an important factor to study human living environment. The Geoscience Laser Altimeter System (GLAS) on ICESat is the first laser-ranging instrument for continuous global observations of the Earth. In order to have a comprehensive understanding of full-waveform laser altimeter, this study simulated the operating mode of ICESat and modeled different terrains’ (pl...

Future detection of Extensive Air Showers (EAS) produced by Ultra High Energy Cosmic Particles (UHECP) by means of space based uorescence telescopes will open a new window on the universe and allow cosmic ray and neutrino astronomy at a level that is virtually impossible for ground based detectors. In this paper we summarize the results obtained in the context of the EUSO project by means of a ...

A simple upwind discretization of the highly coupled non-linear differential equations which define the hydrodynamic model for semiconductors is given in full detail. The hydrodynamic model is able to describe inertia effects which play an increasing role in different fields of optoand microelectronics. A silicon n −n−n-structure is simulated, using the energy-balance model and the full hydrody...

The envelope simulation method, developed earlier for large signal simulation (time domain, TRAN), is extended to include small signal envelope simulation (AC) and DC Sweep simulation (steady state for a range of carrier frequencies). The model is derived for AM, FM and PM modulation schemes and is demonstrated on a piezoelectric transformer circuit. The analytical derivations of the model were...
