Abstract: Electrorheological (ER) lubricant is applied to a rigid rotor system supported by a hydrodynamic bearing that is subjected to a sudden imbalance and a dynamic periodic rotating load. The pressure of the ER film, which ...

Abstract: Proton exchange membrane fuel cell (PEMFC)’s power conditioning system (PCS) for residential application always contains two stage converter configuration of the dc-dc converter and the power grid ...

Abstract: Presently, the “negative sequence current method” is widely used in field-testing to determine torsional vibration characteristics of steam turbine generator rotor systems. The natural frequencies ...

Abstract: A partial contact air bearing model and Archard’s wear law are used to investigate the air bearing and wear characteristics of proximity recording sliders during a take-off process. The air ...

Abstract: The revival of dynamic load/unload (L/UL) technology forces us to rethink the air bearing design philosophy, which has traditionally been established for contact start/stop applications. Reliably ...

Abstract: Exponential growth in both capacity and performance has been exhausting a lot of existing technologies in magnetic hard disk drive industry, one of them being laser zone texturing. Maintaining ...

Abstract: The pressing and challenging demand for resolving the stiction/glide-height conflict, driven by today’s ever decreasing head/disk spacing, forces us to constantly search for new technologies. One ...

Abstract: A comparative study of the nonlinear behavior of reinforced concrete (RC) multistory structures is carried out on the basis of measured response of four six-story, three-bay framed structures, namely a regular bare frame, ...

Abstract: Much attention has been given to mapping the extent of a flood by using optical, radar, digital elevation model (DEM), and river gauge data. The mapped extent is often supported and verified by ground observations. The ...
