Abstract. A number of time resolved optical experiments probing and controlling the spin and charge dynamics of the high mobility two-dimensional electron gas in a GaAs/AlGaAs heterojunction are discussed. These include time resolved reflectivity, luminescence, transient grating, magneto-optical Kerr effect, and electro-optical Kerr effect experiments. The optical experiments provide informatio...

Smart Structures is a rapidly advancing field with the range of support and enabling technologies having made significant advances, notably optics and electronics. Whilst piezoelectric actuators and fiber optic sensors have been accorded the most attention, other techniques such as Shape Memory Alloys, Magneto Restrictive Materials and Electro-Rheological Fluids also have niche applications. Fu...

• Magneto-responsive rheology of highly flowable cement paste with PCE is studied. Flowable magnetic particles and can exhibit MR response. increases relative effect while slightly decreases absolute effect. Applying field plays a major role in stiffness for PCE. Magneto-rheology control, by means adding magnetizable applying field, potential approach to satisfy the contradicting requirements f...

Accurate geometrical models of the head are necessary for solving the forward and inverse problems of magneto- and electro-encephalography (MEG/EEG). Boundary element methods (BEMs) require a geometrical model describing the interfaces between different tissue types. Classically, head models with a nested volume topology have been used. In this paper, we demonstrate how this constraint can be r...

The objective of this paper is to study unsteady magneto hydrodynamic (MHD) free flow viscoelastic fluid (Walter’s B) past an infinite vertical plate through porous medium. temperature assumed be oscillating with time. solution obtained shows different profiles effects slip conditions on primary and secondary velocity. Also, the various parameters temperature, concentration, velocity were prese...
