Computer graphics development

One of the earliest NDT applications for laser-based profilometry systems was for the inspection of marine boiler tubes. Under funding from the U.S. Navy", several systems were developed that were capable of rapidly and accurately mapping the inside surface of 25 mm and 50 mm diameter boiler tubing. Features such as internal pitting and corrosion can be located and quantitatively assessed using computer-graphic analysis. The system employs an... 

Among the current (ca 1997) selection of software systems which together help to exemplify the promise of computer graphics. Advanced Visualization Systems (AVS), stands out as one of the more extensible and practical of them to use. The premise behind development of the system was to provide modelers with a toolkit of modules having sophisticated intrinsics that would enable even casual programmers to link together multiple simple functionahties into a complex constmct with which to accomplish exactly the types of visualization and manipulations that their work required. Researchers... 

The reaction flow-charts of Part Two, and indeed all chemical formulae which appear in this book, were generated by computer. The program used for these drawings was ChemDraw adapted for the Macintosh personal computer by Mr. Stewart Rubenstein of these Laboratories from the molecular graphics computer program developed by our group at Harvard in the 1960 s (E. J. Corey and W. T. Wipke, Science, 1969,166, 178-192) and subsequently refined. 

The opportunity for creative design by viewing many imaginative variations would be blunted if each variation introduced a new set of doubts as to its ability to withstand whatever stress might be applied. From this point of view the development of computer graphics has to be accompanied by an analysis technique capable of determining stress levels, regardless of the shape of the product. This need is met by FEA. 

Because the chemical structure of a molecule encodes its biological properties, structure has long served as the primary variable and determinant for the discovery of new drugs by medicinal chemists. For this reason, systematic structural modification has been the primary tool of choice to isolate and enhance a desired biologic activity. Moreover, with the relatively recent development of in vitro receptor-binding assays, combinatorial methods of chemical synthesis, and computer graphics, the overall approach to structural modification has become increasingly sophisticated. 

Describe the color of the reaction mixtures just before loading onto the column. Make observations about the column development process. Analyze the absorbance data by preparing an elution curve. On graph paper or a computer graphics program, plot 520 (j-axis) versus fraction number. How many peaks were obtained What are the components represented by each peak Use this elution curve to explain the action of a gel filtration column. Explain the fact that phenol red is present in both colored fractions. In what fraction is the bovine serum albumin ... 

One facet of chemistry w hich has benefited greatly from the Use of computer graphics in enhance its own development is x-ray crystallography computers are also used in x-ray structure refinement. 

Using a qualitative approach and implementation of empirical rules, a computer package program which combines computer graphics and molecular mechanics with rule-based correlations was developed to assist the prediction of CD properties from the three-dimensional structure of a molecule197.
