The global attention on refugees and internally displaced persons is reflected in the SDP sector’s variegated attempts to engage and support this target population through its programs. This chapter critically examines contemporary SDP programs and research in this area.

Interface Instability under Forced Displacements
Annales Henri Poincaré, 2006By applying linear response theory and the Onsager principle, the power (per unit area) needed to make a planar interface move with velocity V is found to be equal to V2/ μ, μ a mobility coefficient. To verify such a law, we study a one dimensional model where the interface is the stationary solution of a non local evolution equation, called an ...

Forces and displacements in colon surgery
Surgical Endoscopy, 2002This study aims to find criteria for designing safer laparoscopic graspers for manipulation of delicate tissues. Since the experiment was performed in an open-surgery setup without any movement restrictions, the results are relevant to general surgery as well as laparoscopic.Four surgeons were asked to apply via two clamps enough force to a pig's colon

Displacements that null forces
Proceedings of the 1991 IEEE International Symposium on Intelligent Control, 2002Experimental results indicate that the inner product defined by stiffness does in fact provide the correct force-error nulling directions along which to move a robotic end-effector. These directions, which are defined as the twists of compliance, form the (K)-orthogonal complement to the twists of freedom of a partially constrained gripper (where the ...

New force-displacement metrology for keyboards
Computer Standards & Interfaces, 1997The ergonomic design of computer keyboards has been a popular topic of research during the past decade. Much work has focused on assessing design attributes of keyboards that affect their subjective “feel” during typing tasks. One common measure used for this purpose has been the force-displacement function, which characterizes the force required to ...

Measured forces and displacements of integrated force arrays
SPIE Proceedings, 1995IFAs are MEMS actuators which are powered by the electrostatic forces between the plates of many microscopic deformable capacitors arranged in monolithic arrays. IFAs are fabricated using standard techniques of VLSI electronics. The IFAs reported here resemble thin, flexible plastic membranes 10 mm long and either 1 or 3 mm wide, which contain from 75 ...

Force, Displacement, and Acceleration Sensors
1995This chapter discusses fiber optic and integrated optic sensor concepts. Force, displacement, and acceleration sensors are closely related. A displacement sensor may be used as a force sensor if we know precisely the mechanical constants of the sensor.
