Graphical tools

In the majority of practical finite element simulations the mesh generation is conducted in conjunction with an interactive graphics tool to allow feedback and continuous monitoring of the computational grid. 

FEP, fault tree, gvent tree and piping instrumentation diagram (P ID) editor, accesses ihe package of graphical tools for risk assessment. These tools include the event tree, fault tree and P ID graphical editors. The event tree and fault tree editors are in PSAPACK the P ID editor is in FEP. The event tree editor is used for graphical construction and modification of event trees. The fault tree editor does the same for fault trees the P ID editor does the same for construction and modification of P IDs used in a PSA. 

We have seen here that these simple methods which only rely upon the optimal use of molecular graphics tools can address highly specific receptor-ligand interactions. 

Bota et al. [84] used the PCA method to select the optimum solvent system for TLC separation of seven polycyclic aromatic hydrocarbons. Each solute is treated as a point in a space defined by its retention coordinates along the different solvent composition axes. The PCA method enables the selection of a restricted set of nine available mobile phase systems, and it is a useful graphical tool because scatterplots of loading on planes described by the most important axes will have the effect of separating solvent systems from one other most efficiently. 

The concept of gain and phase margins derived from the Nyquist criterion provides a general relative stability criterion. Frequency response graphical tools such as Bode, Nyquist and Nichols plots can all be used in ensuring that a control system is stable. As in root locus plots, we can only vary one parameter at a time, and the common practice is to vary the proportional gain. 

Computing time was expensive then (about a dollar per second ). Computers filled entire rooms but were slow and incapacious by today s standards, and graphical tools for examining results almost nonexistent. A modeler sent a batch job to a central CPU and waited for the job to execute and produce a printout. If the model ran correctly, the modeler paged through the printout to plot the results by hand. But even at this pace, geochemical modeling was fun ...

A second graphic tool from project management is the Gantt chart, as illustrated in Figure 1.3. This chart allows one to visualize the efforts underway in any one area, such as safety assessment, for all projects that are currently being worked on.

The amount of energy that the steam turbine extracts from the steam depends on the enthalpy drop across the machine. The enthalpy of the steam is a function of its temperature and pressure. One can use a Mollier diagram as a graphic tool to determine the amount of energy available under a particular set of conditions. If in Figure 2.131 the inlet conditions correspond to point and the outlet conditions to point P2, a line drawn between these two points is called the "expansion line" and represents the operation of the turbine as it is extracting energy from the steam. In an ideal turbine, the steam would expand at a constant entropy (isentropically) and the condition of the exhaust steam, from an ideal machine (which has no losses), would correspond to point 3.

The goal of the RMSECV, statistic is twofold. It yields an estimate of the root mean squared prediction error E(y-y)2 when k components are used in the model, whereas the curve of RMSECV, for k = 1,. .., k,ma is a popular graphical tool to choose the optimal number of components. 

RCM is a powerful graphical tool for assessing the feasibility of separations by distillation. As a simple example, Figure 3.11 presents the generation of alternatives for separating a zeotropic mixture with A, B, C from lowest to highest boiler. The initial feed is the point F. Let us consider the segment d,b, as a representation of a simple distillation process (one feed and two products). This obeys the rules ...

A preliminary knowledge of the crystal structure is important prior to a detailed charge density analysis. Direct methods are commonly used to solve structures in the spherical atom approximation. The most popular code is the Shelx from Sheldrick [26] which provides excellent graphical tools for visualization. The refinement of the atom positional parameters and anisotropic temperature factors are carried out by applying the full-matrix least-squares method on a data corrected if found necessary, for absorption and diffuse scattering. Hydrogen atoms are either fixed at idealized positions or located using the difference Fourier technique.
