Optimally dense packings of hyperbolic space

In previous work a probabilistic approach to controlling difficulties of density in hyperbolic space led to a workable notion of optimal density for packings of bodies. In this paper we extend an ergodic theorem of Nevo to provide an appropriate definition of optimal dense packings. Examples are given to illustrate various aspects of the density problem, in particular the shift in emphasis from the analysis of individual packings to spaces of packings.Comment: 27 pages, 11 figure

A Solidification Phenomenon in Random Packings

We prove that uniformly random packings of copies of a certain simply-connected figure in the plane exhibit global connectedness at all sufficiently high densities, but not at low densities

An Evaluation Of Georgia Southern University Public Safety Department\u27s Community Policing Program: A Residence Hall Partnership Program

The Residence Hall Partnership Program (R.H.P.P.) is the first major department wide community policing effort by the Georgia Southern police department. This study is an evaluation of that program’s first year of implementation. The evaluation process consists of a series of two mostly quantitative surveys of the residence hall students and officers of the Georgia Southern police department. The first survey was distributed at the beginning of the program during the Fall 2019 semester, the follow-up survey at the end of the Spring 2020 semester. The theories being examined are that community policing programs will improve student’s perceptions of police, reduce student’s fear of crime, improve officer’s perceptions of students, and improve officer job satisfaction. The results were mixed concerning student’s perceptions of police, and officer job satisfaction. There were positive results for this program improving officer perceptions of students and reducing student’s fear of crime

Utilization of the Space Vision System as an Augmented Reality System For Mission Operations

Augmented reality is a technique whereby computer generated images are superimposed on live images for visual enhancement. Augmented reality can also be characterized as dynamic overlays when computer generated images are registered with moving objects in a live image. This technique has been successfully implemented, with low to medium levels of registration precision, in an NRA funded project entitled, "Improving Human Task Performance with Luminance Images and Dynamic Overlays". Future research is already being planned to also utilize a laboratory-based system where more extensive subject testing can be performed. However successful this might be, the problem will still be whether such a technology can be used with flight hardware. To answer this question, the Canadian Space Vision System (SVS) will be tested as an augmented reality system capable of improving human performance where the operation requires indirect viewing. This system has already been certified for flight and is currently flown on each shuttle mission for station assembly. Successful development and utilization of this system in a ground-based experiment will expand its utilization for on-orbit mission operations. Current research and development regarding the use of augmented reality technology is being simulated using ground-based equipment. This is an appropriate approach for development of symbology (graphics and annotation) optimal for human performance and for development of optimal image registration techniques. It is anticipated that this technology will become more pervasive as it matures. Because we know what and where almost everything is on ISS, this reduces the registration problem and improves the computer model of that reality, making augmented reality an attractive tool, provided we know how to use it. This is the basis for current research in this area. However, there is a missing element to this process. It is the link from this research to the current ISS video system and to flight hardware capable of utilizing this technology. This is the basis for this proposed Space Human Factors Engineering project, the determination of the display symbology within the performance limits of the Space Vision System that will objectively improve human performance. This utilization of existing flight hardware will greatly reduce the costs of implementation for flight. Besides being used onboard shuttle and space station and as a ground-based system for mission operational support, it also has great potential for science and medical training and diagnostics, remote learning, team learning, video/media conferencing, and educational outreach

Letter from Charles R. Bowen to Hubert Creekmore

Bowen writes from New York City to Creekmore in Jackson, Mississippi. He mentions Creekmore\u27s Memphis, Tennessee, essay in Holiday magazine. He discusses his plans for New Year\u27s Eve in Memphis, Tennessee, and a past New Year\u27s Eve in New Orleans, Louisiana. He asks who David Smythe is. Bowen talks about New York during the holidays, hearing Hector Berlioz\u27s L\u27enfance du Christ at Carnegie Hall, reading Simone de Beauvoir\u27s America Day by Day.

Letter from Charles R. Bowen to Hubert Creekmore

Bowen writes from New York City to Creekmore in Jackson, Mississippi. He discusses Creekmore\u27s piece on Memphis, Tennessee, for Holiday magazine, and passes along comments by John [Valentine Schaffner?]. He is sad to hear Random House, Inc. would not consider the Natchez Trace book, but suggests seeing if the Baptist Publishing House in Nashville, Tennessee, might be interested. Bowen discusses his own writings, Elizabeth Spencer\u27s time in Rome, Dylan Thomas\u27s widow, Dr. Sitwell, and Marianne Moore. He mentions travel to Miami Beach, Florida, and Key West, Florida.

A scanning tunneling microscopy based potentiometry technique and its application to the local sensing of the spin Hall effect

A scanning tunneling microscopy based potentiometry technique for the measurements of the local surface electric potential is presented and illustrated by experiments performed on current-carrying thin tungsten films. The obtained results demonstrate a sub-millivolt resolution in the measured surface potential. The application of this potentiometry technique to the local sensing of the spin Hall effect is outlined and some experimental results are reported.Comment: 9 pages and 4 figure
