From grids to pseudo-grids of lines: Resolution and seminormality

On Rich Lines in Grids

From SIMD to Micro-Grids

I. COMPILING TO SIMD PARALLELISM Most commodity microprocessors now support multi-media instructions. These instruction-set extensions are typically based on the Single Instruction-stream Multiple Data-stream (SIMD) model in which a single instruction causes the same mathematical operation to be carried out on many operands, or pairs of operands at the same time. The multi-media instructions on...

Optimum Flat Grids

This paper presents the results of the analysis of 56,000 flat grids in a form suitable for minimum weight design.

the role of russia in transmission of energy from central asia and caucuses to european union

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...

Pseudo-spectral 3D simulations of streamers with adaptively refined grids

A three-dimensional code for the simulation of streamers is introduced. The code is based on a fluid model for oxygen-nitrogen mixtures that includes drift, diffusion and attachement of electrons and creation of new charge carriers through impact ionization and photo-ionization. The electric field created by the space charges is solved self-consistently. The code assumes that the streamer geome...
