Parametric manifolds

Creator:: Boersma, Stuart F.
Abstract:: A standard tool in general relativity is the 3+1 or ADM point of view, namely slicing spacetime into spacelike hypersurfaces of constant time and then describing physics in terms of time-dependent quantities on a typical such hypersurface. Much less well-known is the 1+3 point of view, in which one foliates...

Resource Type:: Dissertation

A new look at the Ashtekar-Magnon energy condition

Creator:: Fischer, James P.
Abstract:: Quantum field theory has enjoyed much success, indeed for ordinary flat spacetime applications it has been experimentally verified to a great deal of accuracy. However on general cursed spacetime backgrounds there is no canonical method for constructing a quantum field theory. In 1975, Abhay Ashtekar and Anne Magnon made progress...

Space time coding in MIMO systems

Creator:: Xian, Liang
Abstract:: Multiple-input multiple-output (MIMO) antenna technology is promising for high-speed wireless communications without increasing the transmission band- width. Space time coding (STC) is a scheme that employs multiple antennas to increase transmission rate or to improve transmission quality. STC is used widely in mobile cellular networks, wireless local area networks (WLAN)...

Automatic time correction for interconnected power system operation

Creator:: Thurein, Ingo Paul
Abstract:: The North American interconnected power systems continuously attempt to hold power system time as close to standard time as possible. All inherent problems associated with normal power system operation make this a difficult task. System time is presently allowed to deviate from standard time by up to two seconds before...

Full Text:: . Present correction methods are manual, time consuming and add to existing operating problems which leads

The effects of computer graphics and mira on aquisition of transformation geometry concepts and development of mental rotation skills in grade eight

Creator:: Pleet, Lawrence Joseph
Abstract:: The purpose of this study was to investigate: (1) whether the use of the Motions computer program will be more effective in the acquisition of transformation geometry concepts in eighth-grade students than the use of the Mira hands-on manipulative, (2) whether the use of the Motions computer program will be...

Preliminary design and analysis of a rotating bubble membrane radiator for space-based nuclear power systems

Creator:: Webb, Brent Jonathan
Abstract:: The development of a novel high temperature space radiator is described. A Rotating Bubble Membrane Radiator (RBMR) combines the best features of heat pipes and droplet radiators while avoiding their negative attributes. The RBMR offers light weight, self deployment, ease of startup and its performance is less affected by acceleration....

Spatial visualization abilities of Central Washington State College prospective elementary and secondary teachers of mathematics

Creator:: Martin, Bernard Loyal
Abstract:: This investigation was designed to determine the extent to which students who are completing planned curricula in mathematics education are proficient in spatial visualization abilities and possess mathematical understandings. The effects of mathematics curricula upon the development of these abilities and understandings and the relationships between these abilities and understandings...

Ultralight fabric reflux tube thermal vacuum testing

Creator:: Pauley, Keith Alan
Abstract:: Five Ultra light Fabric Reflux Tubes (UFRTs) were tested in a thermal vacuum chamber at the National Aeronautics and Space Administration's Johnson Space Center in September 1994. These test articles were design and fabricated by staff at the Pacific Northwest Laboratory, operated by Battelle Memorial Institute for the United States...

Design of a Self-Regulating Deep Space Nuclear Reactor

Creator:: Robinson, Matthew Loren
Abstract:: An enabling technology for long duration, deep space missions is the availability of a high power, long-lived power supply. The goal of this work is the design of a self-regulating deep space nuclear reactor. The design objectives are to produce 250 kWth for a 25-year period using the presence of...
