TL;DR: An integrated molecular graphics and computational chemistry framework is described which has been designed primarily to handle small molecules of up to 300 atoms and provides a means of integrating software from any source into a single framework.
Abstract: An integrated molecular graphics and computational chemistry framework is described which has been designed primarily to handle small molecules of up to 300 atoms. The system provides a means of integrating software from any source into a single framework. It is split into two functional subsystems. The first subsystem, called COSMIC. runs on low-cost, serial-linked colour graphics terminals and allows the user to prepare and examine structural data and to submit them for extensive computational chemistry. Links also allow access to databases, other modelling systems and user-written modules. Much of the output from COSMIC cannot be examined with low level graphics. A second subsystem, called ASTRAL, has been developed for the high-resolution Evans & Sutherland PS300 colour graphics terminal and is designed to manipulate complex display structures. The COSMIC minimisers, geometry investigators, molecular orbital displays, electrostatic isopotential generators and various interfaces and utilities are described.

TL;DR: In this paper, a television receiver is equipped with a graphics generator which is capable of generating a single or multiple graphic images from data representing commercial advertisements stored in a memory device, and the images corresponding to the commercial advertisements are displayed to the consumer when a control function of the TV receiver is activated.
Abstract: A television receiver is equipped with a graphics generator which is capable of generating a single or multiple graphic images from data representing commercial advertisements stored in a memory device. The elements of this arrangement include a micro-controller, a memory device, a graphics and memory controller, a pallet controller and a video switch. The images corresponding to the commercial advertisements are displayed to the consumer when a control function of the television receiver is activated. Alternatively, the images may be displayed in response to an internal clock. The images presented may be static or animated and may occupy a small portion of the screen or the full screen.

TL;DR: This paper shows how the new floating point GPUs can be exploited to perform both analytical and iterative reconstruction from X-ray and functional imaging data, and decompose three popular three-dimensional (3D) reconstruction algorithms into a common set of base modules.
Abstract: The task of reconstructing an object from its projections via tomographic methods is a time-consuming process due to the vast complexity of the data. For this reason, manufacturers of equipment for medical computed tomography (CT) rely mostly on special application specified integrated circuits (ASICs) to obtain the fast reconstruction times required in clinical settings. Although modern CPUs have gained sufficient power in recent years to be competitive for two-dimensional (2D) reconstruction, this is not the case for three-dimensional (3D) reconstructions, especially not when iterative algorithms must be applied. The recent evolution of commodity PC computer graphics boards (GPUs) has the potential to change this picture in a very dramatic way. In this paper we will show how the new floating point GPUs can be exploited to perform both analytical and iterative reconstruction from X-ray and functional imaging data. For this purpose, we decompose three popular three-dimensional (3D) reconstruction algorithms (Feldkamp filtered backprojection, the simultaneous algebraic reconstruction technique, and expectation maximization) into a common set of base modules, which all can be executed on the GPU and their output linked internally. Visualization of the reconstructed object is easily achieved since the object already resides in the graphics hardware, allowing one to run a visualization module at any time to view the reconstruction results. Our implementation allows speedups of over an order of magnitude with respect to CPU implementations, at comparable image quality.

TL;DR: In this article, an enhanced operating environment for an Interactive Real-Time Distributed Navigation System (Figs. 1 and 2) is disclosed, which is provided by improving input and output techniques in a navigation system.
Abstract: An enhanced operating environment for an Interactive Real-Time Distributed Navigation System (Figs. 1 and 2) is disclosed. The environment is provided by improving input and otput techniques (via 218) in a navigation system. Methods for reducing the number of inputs to the navigational system are carried through a wireless device (202). Improved input methods include entering non-deterministic information to retrieve deterministic information. Output techniques include methods for pacing navigational prompts provided by the navigation system.The system is applicable to text, graphics, or audible systems.
