A preliminary experiment definition for video landmark acquisition and tracking

Six scientific objectives/experiments were derived which consisted of agriculture/forestry/range resources, land use, geology/mineral resources, water resources, marine resources and environmental surveys. Computer calculations were then made of the spectral radiance signature of each of 25 candidate targets as seen by a satellite sensor system. An imaging system capable of recognizing, acquiring and tracking specific generic type surface features was defined. A preliminary experiment definition and design of a video Landmark Acquisition and Tracking system is given. This device will search a 10-mile swath while orbiting the earth, looking for land/water interfaces such as coastlines and rivers

Transplantation and the Trauma Surgeon

The number of satisfactory vascular organs suitable for organ transplantation can be increased appreciably by a close working relationship between traumatologists and transplant surgeons. Benefits will derive from more precise and rapid field management of braininjured patients, with subsequent appropriate stabilization. If brain death is declared, prompt referral for organ donation with optimal management should result in well-functioning organs for transplantation. A defined team approach with well-defined protocols could solve most of the medical and moral dilemmas. Compassionate emotional support should be provided for families, particularly minorities, and should extend to inexperienced staff. Underlying these goals are a strong institutional commitment to staff education and an understanding of the lifesaving role that organ transplantation can play. suitable for organ transplantation can be increased appreciably by a close working relationship between traumatologists and transplant surgeons.

A Coordinated Radio Afterglow Program

We describe a ground-based effort to find and study afterglows at centimeter and millimeter wavelengths. We have observed all well-localized gamma-ray bursts in the Northern and Southern sky since BeppoSAX first started providing rapid positions in early 1997. Of the 23 GRBs for which X-ray afterglows have been detected, 10 have optical afterglows and 9 have radio afterglows. A growing number of GRBs have both X-ray and radio afterglows but lack a corresponding optical afterglow.Comment: To appear in Proc. of the 5th Huntsville Gamma-Ray Burst Symposium, 5 pages, LaTe

Exploring the networks of government scientists using Social Network Analysis: a scoping study

Scientists working for the New South Wales (NSW) Office of Environment and Heritage (OEH) provide rigorous evidence and advice to support government priorities which include protecting the natural environment. They also collaborate with and attract non-government researchers to work on government priorities. In this scoping study, we used Social Network Analysis (SNA) to visualise the ego networks of six government scientists from OEH who work on biodiversity conservation and landscape management. This allowed us to explore the potential reach of their advice and information within OEH and beyond; and examine gaps and redundancy in the stacked ego networks

An Interactive Tool for Bayesian Interference

The Bayes Inference Engine (BIE) is a flexible software tool that allows one to interactively define models of radiographic measurement systems and geometric models of experimental objects so that the geometric properties of the objects being radiographed can be inferred from a limited amount of data. The BIE also allows a user to investigate confidence intervals on the estimated object geometry and compare the likelihoods of competing hypotheses

The primary cosmic ray spectrum above 10 to the 19th power eV

Progress on a re-evaluation of the spectrum of cosmic rays determined with the Haverah Park shower array is described. Particular attention is paid to the reality of some giant showers
