in isobaric models for inertial confinement fusion it is assumed that the target configurationat stagnation time (maximum compression) consists of two regions, hot spark and cold fuel, respectively.here the conditions of spark formation and ignition in hydrogen equimolar isotopes in central sparkignition are investigated and permissible values of hs and ts are evaluated numerically. by introduc...

The subpulse drifting phenomenon in pulsar radio emission is considered within the partially screened inner gap model, in which the sub-GoldreichJulian thermionic flow of iron ions or electrons coexists with the spark-associated electron-positron plasma flow. We derive a simple formula that relates the thermal X-ray luminosity Lx from the spark-heated polar cap and the E×B subpulse periodicity ...

gas motion within the cylinder is one of the major factors that control the combustion process in spark ignition engine. it also has significant impact on heat transfer. both the bulk gas motion and the turbulence characteristics of the flow are important and governing the overall behavior of the flow. an arrangement for obtaining a stratified charge, using port injection, is proposed for a cur...

Introduction: One of the most important human senses is vision, which its loss is causing many primary and secondary complications for physical and psychological health such as difficulties in static and dynamic balance. This study aimed to compare the effect of 8 weeks of Spark and Frenkel exercises training on the static and dynamic balance in blind people. ...

The article discusses the issues that arise when determining temperature in region of cathode spot miniature protective spark gaps. modeling principle is used to study field on gap electrode. A mathematical model process compiled basis balance power entering and its removal inside due thermal conductivity. numerical solution obtained nonlinear heat equation with inhomogeneous boundary condition...
