Surface Accuracy Measurement Sensor for Deployable Reflector Antennas (SAMS DRA)

Specifications, system configurations, and concept tests for surface measurement sensors for deployable reflector antennas are presented. Two approaches toward the optical measurement of remote target displacements are discussed: optical ranging, in which the basic measurement is target-to-sensor range; and in particular, optical angular sensing, in which the principle measurements are of target angular displacements lateral to the line of sight. Four representative space antennas are examined

A Duet between the Head and the Heart: the Effect of Love on the Brain

What happens to us when we fall in love? Aside from the symptoms that are normally portrayed in rom-coms and cheesy TV shows, there is so much that happens inside that we are not aware of. For my research project, I want to delve into the scientific and chemical reactions that occur inside the brain and respective systems throughout different phases of love: from the honeymoon phrase to dying of a broken heart . This paper will provide explanations for why we feel or act the way we do, and allow some light to be shed on a subject that some know all too well, and some not at all. To accompany this research paper is a dance work that will have a similar structure. Within multiple sections, dancers will convey the ideas and results presented in my research, and embody the ups and downs of love as a whole. Contrary to popular belief, there is a connection between the head and the heart, and I want to share that information with both romantics and cynics alike

A pilot study of human response to general aviation aircraft noise

A pilot study, conducted to evaluate procedures for measuring the noise impact and community response to general aviation aircraft around Torrance Municipal Airport, a typical large GA airport, employed Torrance Airport's computer-based aircraft noise monitoring system, which includes nine permanent monitor stations surrounding the airport. Some 18 residences near these monitor stations were equipped with digital noise level recorders to measure indoor noise levels. Residents were instructed to fill out annoyance diaries for periods of 5-6 days, logging the time of each annoying aircraft overflight noise event and judging its degree of annoyance on a seven-point scale. Among the noise metrics studied, the differential between outdoor maximum A-weighted noise level of the aircraft and the outdoor background level showed the best correlation with annoyance; this correlation was clearly seen at only high noise levels, And was only slightly better than that using outdoor aircraft noise level alone. The results indicate that, on a national basis, a telephone survey coupled with outdoor noise measurements would provide an efficient and practical means of assessing the noise impact of general aviation aircraft
