This paper describes progress in the design and testing of the log-ratio-based beamposition/intensity measurement module being built for the Low Energy Demonstration Accelerator (LEDA) and Accelerator Production of Tritium (APT) projects at Los Alamos National Laboratory. The VU-based module uses four, 2 MHz if inputs to perform two-axis position measurements and one intensity measurement. To c...

introduction: application of light transmitting posts to restore greatly damaged endodontically treated teeth has been increased. it is suspected that light intensity decreases as it passes throughout different materials. this can reduce the degree of conversion required for adequate bond strength throughout the length of these posts. the objective of this study was to evaluate the amount of li...

A new full-field 3-D micro surface profilometer using digital micromirror device (DMD)-based fringe projection strategy and confocal principle is presented in the article. In viewing the fact that conventional laser confocal measurement method not only easily encounters undesired irregular scattering problems, but also lack scanning efficiency due to its single-point type measurement, the newly...

Commonly accepted intensity-dependent normalization in spotted microarray studies takes account of measurement errors in the differential expression ratio but ignores measurement errors in the total intensity, although the definitions imply the same measurement error components are involved in both statistics. Furthermore, identification of differentially expressed genes is usually considered s...

Previous studies on the question of noise in hospitals have been based on the replies of patients to questionnaires. This paper records what is to our knowledge the first attempt to determine sound levels in a hospital by direct measurement; the work was carried out in the Bristol Royal Infirmary. Some justification is needed for the use of objective sound measurement. Admittedly the intensity ...

Facial expression is an essential and impressive means of human contact. This is important connection of information for knowing emotional case and motive. A facial expression pursues not only emotions, but other creative action, social cooperation and psychological characteristics. Appearance based facial expression recognition systems are analyzed and have pulled widen application. A new stud...
