Current numerical methods have slow dynamic visualisation capability, which is usually separate from the calculation phase. This paper investigates whether an analogue virtual reality (VR) model of a structure can integrate calculation and visual representation. The paper shows how the user can interact with a VR analogue model of a cantilever beam, move a concentrated load along the length of ...

Introduction There are several reasons which cause a face to become deformed: Tumor resections, accidents, growth dysfunctions or several other causes. The reconstruction of these patients should consider functional aspects as well as aesthetical ones. Therefore, a virtual reality system which allows bone cutting, ostheotomy planning, calculation of implants for soft tissue and bones, combined ...

We overview the general status of higher order corrections to Bhabha scattering and review recent progress in the determination of the two-loop virtual corrections. Quite recently, they were derived from combining a massless calculation and contributions with electron sub-loops. For a massive calculation, the self-energy and vertex master integrals are known, while most of the two-loop boxes ar...

A design of power quality monitoring and analysis platform based on the virtual instrument technology is proposed which aims at the key issues affecting quality rural power grids. This article discusses the typical algorithm of harmonic analysis, voltage deviation calculation and unbalance in threephase calculation. Completing software design of power quality monitoring and analysis platform ba...

Abstract--The widespread application of deep sub-micron and multilayer routing techniques makes the interconnection parasitic influence become the main factor to limit the performance of VLSI circuits. Parallel direct boundary element calculation of three-dimensional (3-D) resistance and capacitance is an important method for fas...

A calculation of π → eeγ in next-to-leading order in chiral perturbation theory of two flavour case extended by virtual photons is presented. The whole kinematic sector is covered and realistic experimental situation is discussed.

We apply Bestvina’s approach of calculation of the virtual cohomological dimension of Coxeter groups. The explicit formula for vcdFΓ in terms of cohomological properties of the corresponding complex K is given.

Abstract The current built stock in Europe is large and energetically inefficient due to material decay caused by lifelong use lack of maintenance, combined. New buildings are commissioned delivered everyday with an environmental cost, calculated using the Life Cycle Assessment methodology. LCA now widely requested for new assets, while existing ones left demolition consequent carbon emissions ...

We study the virtual photon structure functions from gauge/string duality. If the Bjorken variable x is not small, supergravity approximation becomes good in dual string theory. We calculate the virtual photon structure functions at large ’t Hooft coupling in a moderate x-region and determine x-behavior of the structure functions. We also show that the Callan-Gross relation FL = 0 is satisfied ...
