The authors utilized a cohort study among Seattle injection drug users (IDUs) to assess whether participation in a syringe exchange program was associated with incidence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection. Susceptible IDU subjects (187 seronegative for antibody to HCV, and 460 seronegative for core antibody to HBV) were(More)
—The use of the web for a variety of educational needs has exploded recently. It provides one approach in the increasing use of electronic media. HTML—the " Lin-gua Franca " of the internet—provides great platform independence. However, for mathematically intensive applications as seen in Engineering, HTTP and HTML are not able to compete with non-web(More)
It is well documented that there is currently an unsatisfied need in industry for more qualified engineers, and a disturbing decline in college students opting for technical degrees. Part of the problem is the high attrition rate among engineering majors, which can be attributed, in large part to problems with mathematics. In addition, the Accreditation(More)
 We are currently developing a new strategy for mathematics assessment and remediation at the University of Nevada Reno (UNR) and the South Dakota School of Mines and Technology (SDSMT). As part of this strategy, electrical engineering students take an on-line test of their ability to use mathematics to solve context-based problems. In this paper, we(More)
The topic of computer vision is of interest due to its ability to provide a great deal of information about the physical world. One problem that plagues many vision applications is that of occlusion. Occlusion is the situation where the view of an object is being blocked by one or more other objects. In this work, a multi-view approach was taken to solve(More)
In this paper, we investigate the boundary between existence and nonexistence for positive solutions of Dirichlet problem ∆u+f (u) = 0, where f has supercritical growth. Pohozaev showed that for convex or polar domains, no positive solutions may be found. Ding and others showed that for domains with non-trivial topology, there are examples of existence of(More)
Computer vision has the potential to discern a large amount of information about the environment. This intelligence can be used to make decisions on navigation and obstacle avoidance. One of the core problems in machine vision is determining the distance from the camera to different objects for a given scene. Stereo-vision is one technique for solving this(More)
The effects of apomorphine and excape learning were examined in normal developing rat pups and littermates preferentially depleted of brain dopamine by the intracisternal administration of 6-hydroxydopamine (6-OHDA) at 5 days of age, a treatment which resulted in a rapid and permanent reduction in brain dopamine to concentrations 12-29% of littermate(More)
Lighting is a constant issue for computer vision applications. The range of light in a scene typically exceeds what an image can accurately represent. Typically, multiple images are taken with each image at a different exposure level. These images are then combined together in order to display more detail than a single image at a single exposure. For(More)
