Abstract The matrix elements of a 2 – D electron gas restricted in GaAs cylindrical quantum wire including Rashba Spin Orbit Interaction, under simultaneous effect hydrostatic pressure and temperature is investigated. strong dependency absolute temperature, on energy band gap effective mass charge carriers the wire, have been found. Because this, linear non-linear properties also get affected. ...

Although improving electrostatic precipitator (ESP) collection of fine particles (micron and submicron sizes) remains of interest, it is not yet clear whether the turbulent flow patterns caused by the presence of electric field and charge in ESPs advance or deteriorate fine particle precipitation process. In this paper, results of the laser flow visualization and Particle Image Velocimetry (PIV...

Magnetoinductive e ects in ferromagnetic conductors can be used for various sensors. Although the principle has been known for a long time, the usefulness of these e ects for practical applications was recognized recently, and intensive investigations began. Magnetoinductive e ects are related to magnetization of a magnetic conductor (wire, strip, thin lm, etc.) by a magnetic eld, which is prod...

In the present study, the neck fracture properties of annealed wire with 1⁄4 20 mm (0.8mil) at 225 C for 1 hour and un-annealed wire were compared. In addition, the microstructural characteristics, the mechanical properties and the texture transition using EBSD methods before and after an electric flame-off (EFO) process were also studied. Experimental results indicate that the recrystallizatio...

In this work, the compound flow control method (passive and active) has been described. EHD actuators as wire-plate (active) and splitter plate (passive) were coupled and applied to control fluid flow and heat transfer around cylinder in cross flow. Investigation consists of the interaction between electric field, fluid flow and temperature field. Experimental tests included various positions o...

The low-current electric discharge from a fine wire anode to a planar cathode in atmospheric pressure air is numerically simulated from high-voltage prebreakdown through electron temperature growth, then ionization and consequent current growth to steady state, limited by a ballast resistor in the external circuit. Conservation of number ~mass! for ions and electrons, Gauss’ law for the self-co...

The spatially dependent description of the electron kinetics in nonuniform electric fields is of primary importance for the modeling of gas-filled proportional counters and other plasma devices. For a typical example, the amplification of the gain signal in the gas counters is determined by the behavior of electron ionization processes in the cylindrically or spherically symmetric electric fiel...

Power electronic modules are widely used in various industries such as aerospace, railway, automotive, alternative energy generation and distribution application for conversion and control of electrical power. An insulated gate bipolar transistor (IGBT) is a power module that is wildly used in various electric products such as power supplies, DC/DC converters and uninterruptible power systems. ...

We solve analytically the multiple-scattering equations for two-dimensional photonic crystals in the long-wavelength limit. Different approximations of the electric and magnetic susceptibilities are presented from a unified pseudopotential point of view. The nature of the so-called plasmon-polariton bands is clarified. Its frequency as a function of the wire radius is discussed. The correspondi...
