Data organization

After the software installation two new directories will have been created in the root directory of the local PC. Assuming that the default pathway was used in the installation the program directory C Teach. .. has the directory structure shown in Fig. 1.2. The second directory C NMRSIM SESSION created contains all the pulse programs, spin systems and experimental set-ups files in the subdirectories C . .. CONFIG configuration files, C . .. HAM spin system files, C . .. PP pulse program files, C . .. WAVE pulse shape files, C . .. LIST lists files and C . .. JOB job files. Table 

1 lists the different file extensions that might be helpful for identification and working with external text editors. The full version of NMR-SIM also creates two additional subdirectories C . .. PP.AMX and C . .. PP.DMX containing the different pulse programming language versions of the pulse programs for BRUKER AM/AMX and DMX/DRX spectrometers. 

In the following discussion it is assumed that the default pathways have been used during the installation process. If different pathways have been selected during the installation this must be taken into account when using the Check its and other references in this book.

Off-line analysis of stored data review of the stored data, organize data in different presentation windows, plot AE and plant parameters data so as to enable comparison and coirelation with the possibility to present data (histogram of AE events vs position, plant parameters and/or AE parameters vs time) conditioned in terms of time interval (initial time, final time) and/or position interval (defined portion of the component = initial coordinate, final coordinate) and/or plant parameters intervals (one or more plant parameters = initial value, final value).

The Centralized Reliability Data Organization (CREDO) is maintained at ORNL to provide a central computer-based source of accurate, timely data and information for use in reliability, availability and maintainability analyses of liquid metal reactors (LMRs). CREDO is a component-based system, that addresses a comprehensive list of 45 genetic components that are representative of all components found at LMRs. 

The first thing we have to decide is whether these matrices should be organized column-wise or row-wise. The spectrum of a single sample consists of the individual absorbance values for each wavelength at which the sample was measured. Should we place this set of absorbance values into the absorbance matrix so that they comprise a column in the matrix, or should we place them into the absorbance matrix so that they comprise a row We have to make the same decision for the concentration matrix. Should the concentration values of the components of each sample be placed into the concentration matrix as a row or as a column in the matrix The decision is totally arbitrary, because we can formulate the various mathematical operations for either row-wise or column-wise data organization. But we do have to choose one or the other. Since Murphy established his laws long before chemometricians came on the scene, it should be no surprise that both conventions are commonly employed throughout the literature ...

Unifying disparate information sources into a single data model is an intrinsically difficult process. Even when the same kinds of information are collected in different places, it is done so for different reasons, which are reflected in data organization. A common example is extraction of information from scientific literature, where the goal is to make a collection of a particular kind of data. Since the origins of the data are research papers, such efforts often result in document databases where the article is the primary entity and the content is represented by various attributes (e.g., lists of referenced molecules). However, a document-oriented database is rarely suitable for the specific requirements of most scientific investigations. Such efforts often invert ...
