Supported by U.S. Army under USAMRAA Grant W81XWH-08-1-0422. Abstract—We provide a preliminary report on work to relate the EMG activity from forearm flexors and extensors to the flexionextension forces generated at the finger tips during constantposture, slowly force-varying contractions. EMG electrode arrays (up to 64 channels) were applied over the(More)
The success of an object-oriented software development project highly depends on how well the designers can capture the Hot Spots of the application domain, that is, those aspects that should be kept flexible to accommodate reuse and change. Yet, all too often, Hot Spots are hardly documented, and over years of software evolution, the source code that(More)
Electromyogram (EMG)-torque modeling is of value to many different application areas, including ergonomics, clinical biomechanics and prosthesis control. One important aspect of EMG-torque modeling is the ability to account for the joint angle influence. This manuscript describes an experimental study which relates the biceps/triceps surface EMG of 12(More)
We have developed a mission concept that uses 3-unit cubesats to perform new measurements of lunar magnetic fields, less than 100 meters above the Moon’s surface. The mission calls for sending the cubesats on impact trajectories to strongly magnetic regions on the surface, and transmitting measurements in real-time to a nearby spacecraft, or directly to the(More)
Numerical simulation of soft tissue mechanical properties is a critical step in developing valuable biomechanical models of live organisms. A cubic Hermitian spline optimization routine is proposed in this paper to model nonlinear experimental force-elongation curves of soft tissues, in particular when modeled as lumped elements. Boundary conditions are(More)

This paper describes an experimental study which relates the simultaneous biceps/triceps surface electromyogram (EMG) of 12 subjects to elbow torque at seven joint angles during constant-posture, quasi-constant-torque contractions. Advanced EMG amplitude (EMGσ) estimation processors were investigated, and an EMG-torque model considering agonist and(More)
Existing commercial hand prostheses can be controlled from the electrical activity (electromyogram or EMG) of remnant muscle tissue within the forearm, but are limited in function to one degree of freedom of proportional control. In a pilot study (N=3 subjects), we used least squares estimation to identify a model between forearm electrical activity(More)
The best solution to making tactical and strategic decisions at a coalition level would be to completely integrate information systems in a seamless manner without considering the various participating countries. Various technological solutions offer the required functionality to accomplish this. Unfortunately, even though considerable efforts are currently(More)
