In this work we report on an investigation of the effect of the magnetic particles size on the effective macroscopic behavior of magnetorheological elastomers (MREs). MREs are a class of smart materials known for their tunable deformation. They are composite materials which consist of ... 詳細を見る

The impact of surface roughness on the optical transmission of light pipes has been addressed using a geometric optics approximation (GOA); however, there has not been a comparison between the GOA and a wave optics solution to evaluate the relative impact of diffraction effects on the ... 詳細を見る

Helicon Injected Inertial Plasma Electrostatic Rocket (HIIPER) [1] is a plasma thruster being researched at University of Illinois Urbana-Champaign. It has been shown in Figure 1. It involves a helicon source along with an Inertial Electrostatic Confinement (IEC) chamber. IEC is a fusion ... 詳細を見る

Electrospray Deposition (ESD) is a process used in manufacturing that utilizes a charged capillary to disperse a flowing liquid into a spray that deposits onto a grounded target substrate. The build-up of charge on the substrate can begin to deflect further spray, allowing the material ... 詳細を見る

Rich literature exists on calculation of copper loss in windings of high-frequency transformers and inductors. Most of the work was carried out in a Dowell approximation ignoring the windings aspect ratio and core presence. Calculation of losses at non-sinusoidal currents is made usually ... 詳細を見る

Devices which scavenge energy from ambient mechanical sources such as human body movement and ocean waves are undergoing rapid research and development. Both triboelectric and piezoelectric effects have been employed in the design of such devices. In this work, we use the MEMS Module in ... 詳細を見る

Magnetic Suspension and Balance Systems (MSBS) are a method of levitating an aerodynamic model in a wind tunnel. An unusual characteristic is that the electromagnet assemblies (outside the wind tunnel) are very large, but the levitated object (a permanent magnet core) is quite small and ... 詳細を見る

Levitation has found important applications in several areas of engineering, from microgravity to transportation systems. Electrodynamic levitation consists of the interaction of a varying in time magnetic field – provided by an alternating voltage supplying a coil or a moving permanent ... 詳細を見る

Introduction Electromagnetic stimulation is a common therapy to support bone healing in cases of avascular necrosis or pseudarthrosis. An electrostimulative screw implant (Asnis III s-series screw in Figure 1) is used to stimulate bone regeneration in the treatment of femoral head ... 詳細を見る

The authors are currently investigating the use of bulk high temperature superconductors as trapped field magnets (TFMs) in order to increase the electrical and magnetic loading of an axial gap, trapped flux-type superconducting electric machine. In electric machines, the use of ... 詳細を見る
