ShelXleis a graphical user interface forSHELXL[Sheldrick, G. M. (2008).Acta Cryst.A64, 112–122], currently the most widely used program for small-molecule structure refinement. It combines an editor with syntax highlighting for theSHELXL-associated .ins (input) and .res (output) files with an interactive graphical display for visualization of a three-dimensional structure including the electron density (Fo) and difference density (Fo–Fc) maps. Special features ofShelXleinclude intuitive atom (re-)naming, a strongly coupled editor, structure visualization in various mono and stereo modes, and a novel way of displaying disorder extending over special positions.ShelXleis completely compatible with all features ofSHELXLand is written entirely in C++ using the Qt4 and FFTW libraries. It is available at no cost for Windows, Linux and Mac-OS X and as source code.

ABSTRACT A comprehensive model of the dynamic, three-dimensional physical fates of contaminants in the marine environment has been developed. For oil spills, dissolution of aromatics from surface slicks and entrained oil droplets are the source of potential effects for biota in the water column. Oil on the surface and along shorelines provides the basis for evaluation of impacts on birds, marine mammals, and recreational activities. A graphical user interface couples the model to a variety of environmental databases and tools to facilitate specific applications and viewing of simulation results.

3D Graphical User Interface

A microwave tip clearance sensor capable of measuring the hottest stages of industrial and aero gas turbines has been developed. This new microwave sensor has been integrated into a commercial package for online real-time monitoring of machine data. However, data analysis of large numbers of tip clearance probes makes standard industry graphic techniques cluttered. A method has been developed to reduce this data and visualize it in order to provide intuitive representations of the data from which a user can quickly draw the right conclusions about machine behavior. The main motivation for the development of a 3D graphical user interface is the density of information that can be shown to the user at one time. Tip clearance measurement is very data-rich, as every individual blade for each sensor mounted around the engine case is available. The result is that it may be difficult to find slight changes within hundreds of clearance trends. Only specialists with long experience in tip clearance measurement can synthesize all the data quickly enough using standard 2D plots. The 3D graphical user interface brings all of this data together to calculate the aggregated blade pattern, rotor positioning, and estimated case shape. All of these measurements are available to the user in a single visualization. Colors indicating alarm or clearance scale quickly draw attention to the most important data such as the minimum clearance point around the engine case where a rub may be likely to occur. This method is based about a case shape fitting algorithm that combines data from multiple sensors to make a case shape estimate based on fitting of a non-uniform rational B-spline (NURB). The scaling is also distorted in order to accentuate the graphics in a way that provides an intuitive understanding of the machine state. The method of applying this data accentuation is important so as to not be misleading. This innovative navigation interface presented in this paper capitalizes on modern advances in computer graphics to aid engineers and operators in understanding, access, monitoring, and analysis of tip clearance and air-gap measurements.

In design, manufacturing and usage of technical products uncertainty arises according to process properties and results in influence of products properties. In current CAD-systems, where products and product properties are presented, uncertainty is not considered yet. In this paper, we propose a new enhanced concept for the visualization of information about uncertainty in CAD-systems. The presentation of uncertainty is realized on basis of three-dimensional parametric models in a CAD-system and an implemented uncertainty-browser. The uncertainty-browser acts as a graphical user interface to categorize information about uncertainty, the processes and product properties. Beyond that, information about uncertainty will be visualized as annotations referring to chosen properties. Being aware of information about uncertainty during product design, the engineer is able to improve his product. The representation of uncertainty is based on an ontology based information system for supporting the collection and categorization of information about processes, products and uncertainty.

In this paper a Graphical User Interface (GUI) platform to supplement teaching and learning in Engineering Mechanics — Statics course is developed. The package encompasses several interrelated modules of the concepts introduced in a typical Statics class. The GUI provides a user-friendly interactive approach to solving problems and displaying the results both numerically and graphically in two- and three-dimensional spaces. In addition to visualization, GUI approach allows users to modify input data and observe the effect on the solution, thus providing students with additional insight to predict the behavior of structures under different loading scenarios.
