Kinetic theory and simulation of collisionless tearing in bifurcated current sheets

Kinetic theory and simulation of collisionless tearing in bifurcated current sheets

Observations from the Earth’s geomagnetic tail have established that the current sheet is often bifurcated with two peaks in the current density. These so-called bifurcated current sheets have also been reported in a variety of simulations and often occur in conjunction with significant temperature anisotropy. In this work, a new self-consistent Vlasov equilibrium is developed that permits both...

Quasi-adiabaticity in bifurcated current sheets

Computer Simulation of the Three-dimensionsal De- Cay of Thin Collisionless Current Sheets

Recent theoretical investigations and simulations of collisionless space plasma current sheets have claimed their stabilisation against reconnection by nite cross-sheet magnetic eld components. However, all these theoretical investigations and simulations were based on two-dimensional models. Currrently we have shown that the energy variations change quite a bit as soon as one considers the pro...

the analysis of the role of the speech acts theory in translating and dubbing hollywood films

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...

Gyrokinetic df simulation of the collisionless and semicollisional tearing mode instability

The evolution of collisionless and semicollisional tearing mode instabilities is studied using an electromagnetic gyrokinetic df particle-in-cell simulation model. Drift-kinetic electrons are used. Linear eigenmode analysis is presented for the case of fixed ions and there is excellent agreement with simulation. A double peaked eigenmode structure is seen indicative of a positive D8. Nonlinear ...
