We have used automatic decomposition electromyography (ADEMG) to measure the configurational and firing properties of 13,206 motor unit action potentials (MUAPs) in the brachial biceps, brachial triceps and anterior tibial muscles of 30 healthy adults (22 men, 8 women; mean age 48.6 +/- 16.9 years, range 20-76) at three levels of isometric contractile force: threshold, 10% of maximum voluntary ...

The process of communication jamming can be modeled as a two-person zero-sum noncooperative dynamic game played between a communicator (a transmitter-receiver pair) and a jammer. We consider a one-way time-slotted packet radio communication link in the presence of a jammer, where the data rate is fixed and 1) in each slot, the communicator and jammer choose their respective power levels in a ra...

Little is known about the mechanism that regulates the sensitivity of rod system at its normal operating light levels. Two experiments are reported in this paper. First, we searched for nonlinear distortion products in rod vision that could be generated from any local adaptation process, using a sensitive experimental procedure that has demonstrated local adaptation in cone vision. No local ada...

A threshold counter is a shared data structure that assumes integer values It provides two operations Increment changes the current counter value from v to v while Read returns the value bv wc where v is the current counter value and w is a xed constant Thus the Read operation returns the approximate value of the counter to within the constant w Threshold counters have many potential uses inclu...

This paper describes a real time feature extraction for real-time surveillance system. We use incremental KPCA method in order to represent images in a low-dimensional subspace for real-time surveillance in the traditional approach to calculate these eigen space models, known as batch PCA method, model must capture all the images needed to build the internal representation. Updating of the exis...

The anomalies of the temperature dependences of the logarithmic decrement and eigen frequency of the free damped vibrations for Fe-Co-Ni-Ti shape memory alloys were first found in the vicinity of the reverse ay martensitic transformation. It was shown the damping capacity in the alloys investigated is comparable with that for TiNi based alloys.

This paper presents a fast incremental algorithm for low rank approximations or dimensionality reduction of matrices. Assuming that matrices have double-sided type of decomposition, we can set up an incremental solution that constitutes two coupled eigenmodels and thus a two-step updating procedure. At each step, we first represent row-row or column-column covariance matrix as the form of eigen...
