per year. T he field of medicine is a natural application for distributed, collaborative multimedia systems. The data types, manipulations, and user interactions are broad and demanding, since the medical environment involves potentially life-critical decisions and integration of a rich data set. One area where a collaborative system can substantially improve patient care is clinical neurophysi...
A new touch sensor device has been demonstrated with molybdenum disulfide (MoS2) field effect transistors stacked with a piezoelectric polymer, polyvinylidene fluoride-trifluoroethylene (PVDF-TrFE). The performance of two device stack structures, metal/PVDF-TrFE/MoS2 (MPM) and metal/PVDF-TrFE/Al2O3/MoS2 (MPAM), were compared as a function of the thickness of PVDF-TrFE and Al2O3. The sensitivity...
PUP Compensator In this paper, we consider linear time-invariant multi-input multi-output (MIMO) systems that are stabilizable by proportionalintegral (PI) compensators. Such systems are also stabilizable by a PI-type compensator to be denoted by PIP. The P I P compensator consists of a PI compensator in the feedforward loop preceding the plant to be controlled, and a proportional gain in a fee...
A pentagon in the plane with fixed side-lengths has a two-dimensional shape space. Considering the pentagon as a mechanical system with point masses at the corners we answer the question of how much the pentagon can rotate with zero angular momentum. We show that the shape space of the equilateral pentagon has genus 4 and find a fundamental region by discrete symmetry reduction with respect to ...
It is well-known that closing the loop around an exponentially stable, nite-dimensional , linear, time-invariant plant with square transfer-function matrix G(s) compensated by a controller of the form (k=s)? 0 , where k 2 R and ? 0 2 R mm , will result in an exponentially stable closed-loop system which achieves tracking of arbitrary constant reference signals, provided that (i) all the eigenva...
Autonomous Dynamical Systems (DS) has emerged as an extremely flexible and powerful method for modeling robotic tasks. Task execution of DS models is typically done in an open-loop manner in combination with standard low level controller, e.g. position controller or impedance controller. Such an arrangement has two important drawbacks 1) it is not passive and 2) the DS model can not respond to ...
