Tests of a third generation multianode phototube

We report on results of tests of the 16-channel Hamamatsu R5900-M16 photomultiplier tube for gain uniformity and stability, pixel uniformity, linearity, cross-talk, and quantum efficiency. These parameters are essential to our application; i.e., the read...

DCT-based a new approach of improving image coder performance using the spatial reconstructing noise shaping

A modification of the DCT based coding system is proposed that allows to suppress the reconstruction noise in the frequency bands where it is less visible. The modified coder is compatible with the standard DCT system. A 1-D noise feedback filter is proposed...

Prediction of stresses in hydrocarbon bearing structures using seismics

If we have data about the rock density, velocities of P- and S-waves and the configuration of layers interfaces, we can formulate a problem of stress-strain aituation in any point of the seismic geological section.

Design and construction of a small-scale model of a high-temperature superconducting magnetically levitated vehicle

The design of a small-scale model of a magnetically levitated vehicle is presented in the paper. The model has been constructed on the basis of the calculation of the magnetic field and forces between permanent magnets and high temperature superconducting...

Low-complexity symbol clock recovery and segment synchronization algorithm for the grand alliance VSB HDTV system

A simple full-digital synchronization scheme is proposed for baseband G-A VSB HDTV signals, where segment synchronization is performed prior to symbol clock recovery using the segment synchronization symbol in the received signal. Modifications significantly...

Vowel environments in minimal pair sequences

An earlier study replicated the global fundamental frequency declination effect over the minimal pair sentences used here. In order to test for local influences near word boundaries, three classes of measurements (duration, mean fundamental frequency,...
