Based on a general methodology using natural coordinates , a three-dimensional whole body response model for the articulated human body is presented in this paper. The joints between biomechanical segments are defined by forcing adjacent bodies to share common points and vectors that are used in their definition. A realistic relative range of motion for the(More)
A fully integrated switchable dual-band low-noise amplifier (DB-LNA) for 802.11b/g and WiMAX applications is presented. By using switch effective inductance technique for the input matching network (IMN) and a switched LC tank to tune the amplifier gain, dual-band operation for 2.4 GHz and 3.5 GHz bands is achieved. Using a standard 0.18um CMOS process, a(More)
We measure and model the steady transport of specific conductivity and dissolved oxygen through a groundwater plume from a highway infiltration basin in southeastern Massachusetts. Specific conductivity is treated as a conservative surrogate for runoff contamination , and the data calibrate a 0.27-m vertical dispersivity ␣ of the aquifer and the bottom(More)
