The problem of path planning for a robotic system is considered, under the conditions in which both the target to be reached and the obstacles with which collision must be avoided are moving in a way not known in advance. ...

Thin films of lithium niobate on various oriented sapphire substrates were fabricated by the rf sputtering method. Polarized He-Ne laser light with a wavelength of 6328 A was successfully coupled into the optical waveguides ...

Characteristics of an injection-controlled electron-beam pumped XeF(C $\to$ A) excimer laser have been investigated with emphasis on efficient wideband tuning and scaling issues. Using a quasi-cw dye laser as an injection ...

In this study we examine the effects of implementing the Radix 2, the Radix 4 and the Prime Factor Fast Fourier Transform algorithms on two instances of message-based multiprocessor architectures. The machines we use are ...

In this work, we are concerned with power efficient communication techniques for wireless mobile devices. In this direction the effects of nonlinear amplifiers in communications systems are first studied, as they tend to ...

A comprehensive theory of conduction in polycrystalline silicon is presented. The present approach fundamentally differs from previous theories in its treatment of the grain boundary. This theory regards the grain boundary ...

Magnetic Resonance (MR) imaging is a 3-D, multi-slice, radiological technique that acquires multiple intensities corresponding to each voxel. The transverse relaxation time, T$\sb1$, and the axial relaxation time, T$\sb2$, ...

Time series are often modeled as filtered versions of white noise, the filter being linear. We study non-Gaussian processes by modeling them similarly, but allowing the possibility of the filter being non-linear. These ...

The task of stabilizing communication networks sharing a spread spectrum channel is addressed. A slotted system is considered and the stabilization is achieved by controlling the number of packets that are transmitted in ...
