Documentation abstracts, useful as they are, may also prove inadequate for final decisions, which would make it necessary for the searcher to obtain and examine copies of full patent specifications. Although the increasing availabihty of sets of full specifications on CD-ROM at modest cost is making it easier for searchers to have in their collections copies of those specifications they might need to consult, the necessity to go beyond computer output, whether to abstracts or full specifications, is stiU one of the bottlenecks of computer searching, and therefore an area in which significant new developments are hoped for. 

It is now possible to "see" the spatial nature of molecular orbitals (10). This information has always been available in the voluminous output from quantum mechanics programs, but it can be discerned much more rapidly when presented in visual form. Chemical reactivity is often governed by the nature of the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO). Spectroscopic phenomena usually depend on the HOMO and higher energy unoccupied states, all of which can be displayed and examined in detail. 

An example of an elementary voltage feedbaek applieation is the nonisolated, single-output switehing power supply. If we negleet the error amplifier eompensation, then the design is quite simple. Tet us examine a situation where a 5 V output is regulated and a 2.5 V referenee is provided within the eontrol IC. This ean be seen in Figure 3-43. 

Let us again examine the power supply with +5 V, +f2 V, and -12 V outputs. Sinee +/-12V loads usually provide power to op amplifiers that are relatively immune to variations on their Vee and VEE supply lines, their voltage regulation ean be looser. Using the same situation as the first example in this seetion, Ri is 2.49 K and a sense eurrent of 1.004 mA. 

Let us examine how one determines the values of the inductor and capacitor. Several assumptions have to be made at the beginning of the design process since several of the tank circuit s characteristics are variable within the application. The first is to assume a value for the Q of the tank circuit. In the application, the Q varies greatly with the amount of load placed on the output of the supply. So, a good value to start with is... 

Subcontractor/supplier performance will be evident from audit reports, surveillance visit reports, and receipt inspections carried out by you or the third party if one has been employed. You need to examine these documents for evidence that the subcontractor s quality system is controlling the quality of the products and services supplied. You can determine the effectiveness of these controls by periodic review of the subcontractor s performance what some firms call vendor rating . By collecting data on the performance of subcontractors/suppliers over a long period you can measure their effectiveness and rate them on a scale from excellent to poor. In such cases you should measure at least three characteristics quality, delivery, and service. Quality would be measured by the ratio of defective conforming products received delivery would be measured by the number of days early or late and service would be measured by the responsiveness to actions requested by you on scale of excellent to poor. The output of these reviews should be in the form of updates to the list of assessed subcontractors/suppliers. 

During the PHEA stage, the analyst has to identify likely human errors and possible ways of error detection and recovery. The PHEA prompts the analyst to examine the main performance-influencing factors (PIFs) (see Chapter 3) which can contribute to critical errors. All the task steps at the bottom level of the HTA are analyzed in turn to identify likely error modes, their potential for recovery, their safety or quality consequences, and the main performance-influencing factors (PIFs) which can give rise to these errors. In this case study, credible errors were found for the majority of the task steps and each error had multiple causes. An analysis of two operations from the HTA is presented to illustrate the outputs of the PHEA. Figure 7.12 shows a PHEA of the two following tasks Receive instructions to pump and Reset system. 

The RR and SS forms both have a dipole moment of 2.8 debye along the negative Z-axis. To locate this within the molecule, we need to examine the standard orientation. Here is the output for the RR form ... 

If an optimization tuns out of steps, do not blindly assume that increasing the number of steps will fix the problem. Examine the output and determine whether the optimization was making progress or not. For example this command will provide a quick summary of an optimization s progress on a UNIX system (blank lines ate added for readability) ... 

This becomes even clearer when we examine the alternate version gf this normal mode included later in the output, labeled as the eigenvector of the Hessian ... 

Run a single-point energy calculation on methanol using the HF/6-31++G(d,p) model chemistry, including the GFPrint and GFinput keywords in the route section which request that the basis set information be included in the output file (in tabular and input format, respectively). Examine the basis set output and identify its main components. 

The job s output goes to the file h2o.log. We ll look at the output in more detail later. For now, we ll examine it only briefly. 

This concludes the UNIX and VMS-specific portion of the tutorial. Turn to page xlix to continue learning about Gaussian, where we examine Gaussian output. 

Output is added to the output display area as it is produced by the program. This area is horizontally and vertically scrollable and may be examined at any point throughout job execution. 

Examine the job output, and locate the following lines near the end of the output window ... 

In determining the area required for increased production the relationship between the output and the area may not be linear, and needs to be examined in some detail. When the output required exceeds the maximum output of a process line then increased shift working may be considered. Alternatively, a second process line may be needed. 

The model for the maintenance requirements of a large metallurgical plant was recently constructed by relating the man-hours to the production output, but the relationship was not linear, and a more sophisticated model was needed to examine the site requirements for different output tonnage.
