WATERFLOODING FRONT MOVING TASK IN DUAL PERIODICAL AREA: PISTON-LIKE DISPLACEMENT CASE

An Ironless Large Displacement Flat Piston Loudspeaker

This paper presents a small wide-band loudspeaker. Particular efforts have been made to reduce the nonlinearities of the loudspeaker as much as possible. The motor structure is completely ironless, the elastomer suspensions are replaced by ferrofluid seals and a monobloc carbon foam piston substitutes the traditional conic membrane. The circular radiating surface, which is flat, has a diameter ...

Keratoplasty: Moving to the Front

Penetrating keratoplasty (PKP) has a long track record of high success rates compared to other tissue and organ transplantations. Despite the immunologic privilege of the cornea, the issue of immunological rejection cannot be overlooked and endothelial rejection is observed in up to 20% of eyes undergoing PKP. 1 Repeat keratoplasties after rejection are increasingly more prone to rejection and ...

Viscous stabilization of the invasion front in drainage displacement

We investigate the stabilization mechanisms due to viscous forces of the invasion front in drainage displacement in two dimensional porous media using a network simulator. We find that in horizontal displacement the capillary pressure difference between two different points along the front vary linearly as function of height separation in the direction of the displacement. We conclude that exis...

Running head : DUAL - TASK INTERFERENCE WITH EQUAL TASK EMPHASIS Dual

Most studies using the Psychological Refractory Period (PRP) design suggest that dual-task performance is limited by a central bottleneck. Because subjects are usually told to emphasize Task 1, however, the bottleneck might reflect a strategic choice rather than a structural limitation. To address the possibility that central operations can proceed in parallel, albeit with capacity limitations,...
