File Problem

An example of file problem with species with multiple four-membered rings is seen in the inorganic chemical literature involving — P< in lieu of — CH<. The standard form of elemental phosphorus is P4 with 60° P—P—P angles. Trivalent phosphorus enjoys angles of somewhat over 90°. So, why is cubic Pg with P—P—P angles of 90° less stable than P4 Theorists have found this last question of considerable interest. See file nearly contemporaneous papers ... 

You can use the Windows SCANDISK utility to correct corrupt file problems or disk errors, like cross-linked files (which CHKDSK can t do). There are two ways you can use SCANDISK. First, if you suspect a particular hard disk is having... 

Symptoms of swap file problems include extremely slow system speed and a disk that is constantly being accessed, which is referred to as ...

In the previous chapter, we saw that if matter is infinitely divisible, then file problem of seepage gets even more complicated. Kim has to postulate closure oeeurring... 

In addition the fuel vendors are requested to improve the fuel assembly design to mitigate file problem. The remedies are the following ... 

All CD s are stored in a CD-jukebox (100 CD s per jukebox), and are accessible to all HP9000 workstations under HP-UX 9.05 via the fXOS software (Ixos-Jukeman VI.3b). The Ixos-Jukeinan software has a slow time response for filenames searches on the jukeboxes. This problem has been encompassed. Laborelec has developed a dedicated static database software. This database is loaded once for all after burning and verifying CD s. All CD s are read from the jukebox and all the filenames are saved in this database. One jukebox can contain more than 65.000 records. This dedicated software retrieves files from jukebox almost instantaneously. 

As this short example shows. PDB files use different syntax for different records and both writing and reading such files require much effort. Another problem is the extensibility of this format to handle new kinds of information, which further complicates the file structure. The Protein Data Bank has been faced with the consequences - the existing legacy data comply with several different PDB formats, so they are not uniform and they arc more difEcuh to handle (145, 155, 157]. As mentioned in Section 2,9.7.1, there is a much more flexible and general way of representing molecular structure codes and associated information - the STAR file format and the file formats based on it. 

The Self-defining Text Archive and Retrieval (STAR) file format addresses primarily the problem of the inflexibility of the PDB file format, its fixed sets of allowable fields, and their strong dependence on order, To overcome the problems described, both the data. structure and the actual data items within a STAR file arc self-defined, which means that they are preceeded by corresponding names (labels) which identify and describe the data. The data may be of any type and there is no predefined order of the data. STAR files, in contrast to PDB files, are easy to read and write manually. The whole syntax of STAR files is very simple and is defined by only a few rules ... 

Given the bond distances and intemuclear angle in Problem 9, what is the moment of inertia of the H2O molecule about its principal axis through the oxygen atom (the y-axis in File 4-5) ... 

At the top of File Segment 5-1 is a heat of fomiation information block. Two sums are listed One is a sum of nomial bond enthalpies for ethylene, and the other is a sum selected from a parameter set of stiainless bonds. Both sets of bond enthalpies have been empirically chosen. A group of molecules selected as nomial generates one parameter set, and a group supposed to be strainless is selected to generate a second set of str ainless bond enthalpies designated SBE in Eile Segment 5-1. The subject of parameterization has been treated in detail in Chapter 4. See Computer Projects 3-6 and 3-7 for the specific problem of bond enthalpies. 

The remainder of the input file gives the basis set. The line, 1 0, specifies the atom center 1 (the only atom in this case) and is terminated by 0. The next line contains a shell type, S for the Is orbital, tells the system that there is 1 primitive Gaussian, and gives the scale factor as 1.0 (unsealed). The next line gives Y = 0.282942 for the Gaussian function and a contiaction coefficient. This is the value of Y, the Gaussian exponential parameter that we found in Computer Project 6-1, Part B. [The precise value for y comes from the closed solution for this problem S/Oir (McWeeny, 1979).] There is only one function, so the contiaction coefficient is 1.0. The line of asterisks tells the system that the input is complete. 

In response to the first office action, the appHcant may file a series of amendments (step 6) and should provide substantial reasoning and analysis to explain the reasons that the pubHcation(s) cited by the examiner do(es) not disclose the invention as it has been claimed. The patent appHcant s response should also comply with the examiner s request for correcting formal problems in the appHcation. 

The Notice of Errors. The first mechanism for correction of errors is called a "Notice of Errors." This document may be filed by the patentee after issuance of the patent with the U.S. PTO and references the patent number, issue date, and the errors contained in the patent. The purpose of a Notice of Errors is to clarify the examination history of the patent and such notice dispositively corrects any misspellings, or typographical errors or omissions. One example of a problem which may be clarified by a Notice of Errors is an omitted chemical bond in a compound used in an exemplary embodiment of the invention. In short, the error is obvious and easily corrected. 

Most new patent cases of interest are pubHshed by at least one of the U.S., European, or Japanese patent offices, and WIPO (PCT). Japan presents problems for those not able to read Japanese, but the U.S. Official Ga tte (with representative claims) and PCT Ga tte (with English-language abstracts) can be in one s hands within a week of patent pubHcation. Similar timing is available for the European Patent Office bulletin which contains trilingual tides and the on-line EPAT file and various CD-ROM products. A highly effective alerting program can be developed from a combination of these methods. 

Image Files. Only the physical problem of moving or storing files has been discussed herein. The format in which the data is actually stored or transmitted is another part of the process. There are a number of file formats, many of which are proprietary, developed to suit the needs of a particular computer platform or software appHcation. There has been some effort to standardize to a few file types, but many others are in use. A thorough discussion of graphics file formats is available (20). 

Script file fig627.m produces the Nichols chart for Example 6.4 when K = 4, as illustrated in Figure 6.27. The command ngrid produces the closed-loop magnitude and phase contours and axis provides user-defined axes. Some versions of MATLAB appear to have problems with the nichols command.
