Fields, in user interfaces

Realistic treatment of most crystallizers requires modeling turbulent high concentration two phase flow, which is at the cutting edge of CFD development. Recent advances both in constitutive relations and computer processor speed have advanced this field, but there are still significant limitations. New developments in user interfaces and the general decrease in cost of computational... 

Many tools that could prove to be extremely useful for your particular field of research are being developed in bioinformatics groups all over the world. These programs are typically just a couple of mouse clicks away and can be downloaded and used free of charge. In most cases, however, these tools are rarely converted into webtools and usually don t come with a fancy graphical user interface. 

The field was comprehensively reviewed by Duff (25) in 1977. The design features of sparse matrix codes are discussed by Duff and Reid (26) and the need for suitable user interfaces is the subject of a paper by George and Liu (27). Generally the goal of the... 

GAMMA is a good example of many of the benefits and compromises listed previously. The bulk of the library was the doctoral work of Dr. Scott Smith at the Eidgenoessische Technische Hochschule (ETH) in Zurich, Switzerland. Subsequently, Dr. Smith took a job at the National High Field Magnetic Laboratory in Florida. Both sites shared in hosting a web site to provide open access to the source code, examples, documentation and compiled binaries for many platforms and compilers. As a code library, many of the obstacles to cross-platform support go away, especially the need to support an application across different graphical user interfaces. 

Conformity with user expectations describes the uniformity and consistency of a dialogue system. Consistency means the rule observance of the design of the user interface and the dialogue steps, so that similar user inputs lead to similar reactions of the system in related situations. Conformity with user expectations also includes the adaptation of the dialogue system to the user s characteristics. It includes understanding the state of knowledge of the user in his field of work, his education and experience, as well as the generally accepted conventions. 

Many of the topics treated in Volumes 1-4 are still of interest to a small band of professional theoretical chemists. Twenty years ago, Molecular Mechanics was in its infancy. A number of calculations had been reported for hydrocarbons, but force fields were rather primitive, as was the graphical user interface. In my opinion, it was the GUI that was responsible for the exponential growth of Molecular Mechanics and Molecular Dynamics. Many... 

The boxes in the network are called modules, and the lines connecting them are called datapipes. The point of attachment, where a datapipe attaches to a module, is called a datapoit, the dataports on the tops of the modules are input ports, and the ports on the bottoms of the modules are output ports. In SClRun, the dataports are color-coded to indicate the type of the data. For example, the blue datapipes are for Matrices, and the yellow datapipes are for Fields. Fields are used to represent 3D geometry, as well as the data values that are defined over that geometry. Taken as a whole, the collection of modules and datapipes in a dataflow apphcation is called a network, or net Each module can have an optional user-interface (Ul) button on its module if the user presses the U1 button, a separate window appears, with controls for viewing and modifying the state of the module s parameters. 

The user interface is designed using a menu technique the implementation today is in DEC S Forms Management System (FMS). It consists of a sequence of menus which allows the user to select different input and query functions. A function is selected by hitting only one key. Pre-selections on each level are available as well as a header line, providing information on the position of the current screen in the menu hierarchy. Another feature to facilitate usage of the system is the help facility for menu screens, where some fields have to be entered to specify query parameters, help is available for each field.
