We experimentally studied the magneto-photocurrents generated by direct interband transition in InAs/GaSb type II superlattice. By varying the magnetic field direction, we observed that an in-plane magnetic field induces a photocurrent linearly proportional to the magnetic field; however, a magnetic field tilted to the sample plane induces a photocurrent presenting quadratic magnetic field depe...

This paper presents the design, fabrication and evaluation of magneto-rheological damper. Semi-active control devices have received significant attention in recent years because they offer the adaptability of active control devices without requiring the associated large power sources. Magneto-Rheological (MR) dampers are semiactive control devices that use MR fluids to produce controllable damp...

We present a model for the compression and heating of the ICM by powerful radio galaxies and quasars. Based on a self-similar model of the dynamical evolution of FRII-type objects we numerically integrate the hydro-dynamic equations governing the flow of the shocked ICM in between the bow shock and the radio lobes of these sources. The resulting gas properties are presented and discussed. The X...

Failure to adequately define or understand the use of storage water in hydroelectric system has created a fragmented economic environment and schizophrenia in the industry that has the potential to limit its development as a global industry. This paper suggests that, by redefining the use of storage of water in hydroelectric system as a means of using a decision support system to obtain the eff...

The reaction turbines have application in very wide range hydro power projects. The turbines are the most important components of any hydro power plant. Its cost varies 15-35% of the total cost of hydropower project. Thus the cost effective design of the turbine is of utmost importance. It is very crucial to understand the flow behavior of the turbine under various operating conditions. The mod...

The ability to determine static and (hydro)dynamic properties of carbon nanotubes (CNTs) is crucial for many applications. While their static properties (e.g., solubility and wettability) are fairly well understood, their mechanical responses (e.g., deflection under shear) to ambient fluid flow are to a large extent unknown. We analyze the elastic response of single-walled CNT forests, attached...

Magnetic linear gear provides a new and unique opportunity for coupling mechanical impedances and optimizing vibration damping. In the present paper a new magneto-mechanical vibration damper (the so-called Z-damper) is described. Its expected theoretical dynamic behavior shows a particularly high damping capability, a low frequency, as well as an optimal behavior for high frequencies.
