The most common computer authentication method is to use alphanumerical usernames and passwords. This method has been shown to have significant drawbacks. For example, users tend to pick passwords that can be easily guessed. On the other hand, if a password is hard to guess, then it is often hard to remember. To address this problem, some researchers have… (More)
We have exploited the complementary arrangement of afferents in a coronal slice (300-400 microm) of the rat olfactory tubercle (OT) maintained in vitro to investigate transmission in two separate synaptic pathways. We recorded extracellular responses within the OT dense cell layer in slices and stimulated either the outermost layer to activate primary… (More)
The most exciting recent advance in computer graphics has been the development of programmable Graphics Processing Units (GPUs). We discuss different approaches to and some of the issues involved in teaching the use of GPUs.
Molecular modeling is an important research area, helping scientists develop new drugs against diseases such as AIDS and cancer. Prior studies have demonstrated that immersive virtual environments have unique advantages over desktop systems in visualizing molecular models. However, exploration and interaction in existing molecular modeling virtual… (More)
Over the past decade, there have been major advances in the computer graphics field: in computer graphics techniques, the trend towards object-oriented programming, and availability of relatively inexpensive, high-resolution graphics hardware and sophisticated rendering packages. This suggests that a reevaluation of the traditional computer graphics… (More)
panelists will discuss various approaches to teaching an introductory computer graphics course. They represent a wide spectrum of the discipline, offering courses emphasizing systems, engineering, mathematics, science, art design and animation. Sample course syllabi, textbook recommendations, software packages and suggested projects will be available. This… (More)
In the past few years there have been significant advances in both the computational and graphics capabilities of micro-computers. In graphics the standard (for the IBM compatible world) has advanced from the Computer Graphics Adapter (CGA) through the Enhanced Graphics Adapter (EGA) to the present Video Graphics Array (VGA). With the multiple color… (More)
A computer graphics course is extremely hardware system dependent, even more than most computer science courses. To produce high quality graphics images requires a high resolution system with extensive color capability and a fast cpu. Fortunately, the computer graphics capabilities of inexpensive systems have continued to increase. As this trend continues… (More)
