Sio2-Si Film-Substrate Single-Reflection Retarders For Different Mercury Spectral Lines, A.R.M. Zaghloul, R.M.A Azzam

Department of Electrical and Computer Engineering: Faculty Publications

Design parameters for SiO₂- Si film-substrate single reflection retarders for several mercury spectral lines are presented. An example of an angle-of-incidence tunable retarder (AITR) capable of multiple wavelength operation (MWO) is reported Simple, approximate formulae for calculating film-substrate retarder design parameters (least film thickness d' and incidence angle) are presented.

Electronic Color Scanners, Kenneth Francis Hird

Graduate Research Papers

Process color photography has been continually developing for many years. In fact, color printing techniques are still benefiting, through additional sophisticated requirements, and from a discovery made about 300 years ago. At that time Sir Isaac Newton, British scientist, mathematician • and philosopher, placed a glass prism in the path of a narrow beam of sunlight entering his room through a pinhole in an opaque window shade. He determined that ordinary white light is a mixture of colored lights.

Unfortunately, in practice, ideal pigments for three-color inks do not exist and this impasse greatly complicates the job for the photo-processor. …

Hall Effect Magnetometer, John A. Woollam, Harry A. Beale, Ian L. Spain

Department of Electrical and Computer Engineering: Faculty Publications

A magnetometer utilizing a single crystal of Bi²Se³ having a rhombohedral crystal structure is described along with a method for making such a device. The Bi²Se³ has a positive or negative Hall coefficient and a carrier concentration of about 10¹⁸to10²⁰ per cubic centimeter.

Digital Video Display System Using Cathode-Ray Tube, George M. Low, Arthur I. Zygielbaum, Warren L. Martin, Alexander Engel

School of Natural Resources: Faculty Publications

A digital video display system (DWDS) is disclosed for display of image, alphanumeric and other data on a cathode-ray tube (CRT) with sequential raster scan and two, four or eight gray shades. The DVDS includes a central processing unit for ac tivating the system, selecting the X (horizontal axis) and Z (in tensity modulation) modes, and designating the starting loca tion of two successive rasters of data from a memory accessed by a data multiplexer subsystem (DMS). At the end of each raster, the DMS interrupts the computer for a new starting lo cation of a raster of data to …

Systems Reliability Using The Flow Graph, Kenneth Edward Farrier

Dissertations and Theses

The problem of calculating the reliability of a complex system of interacting elements is delineated to a linear system, no element of the system having a reliability distribution in terms of any other e1ement of the system, where only one path is taken through the system at a time. A precise definition is then developed to specify the reliability of the linear, single path at a time, system. A precise and concise generating function is found that effortlessly produces the reliability of the linear, single path at a time, system directly from the reliability flew graph of the system.
