Continuous numerical data

Some of the subgroups which are of special interest are the Office of Scientific Personnel the Office of Documentation the Nuclear Data Project which publishes Nuclear Data Tables, Nuclear Reaction Graphs, and Nuclear Theory Cards Office of Critical Tables, which publishes the Directory of Continuing Numerical Data Projects and the Prevention of Deterioration Center which publishes Prevention of Deterioration Ahstracts, Environmental Effects on Materials and Equipment Abstracts, and PDC Newsletter. The Cardiovascular Literature Project which recently left NAS-NRC is now operating as the Washington office of the Institute for Advancement of Medical Communications. 

All the preceding discussion has concerned continuous numerical data. Not all data is of this form, and we now discuss the encoding of nonnumerical data. Logical variables have one of two values that are encoded as zero and one. An example is the presence or absence (a yes or no) of a feature. Typically the presence (yes) is encoded as a 1 and the absence (no) as a 0. Categorical data should be encoded in some variation of a one-of-N code (N equals the number of categories) or a thermometer code. 

That measurement may be numerical and continuous, as in determining the concentration of cocaine, or categorical (yes/no green/orange/blue, and so on). We will focus attention on continuous numerical data. 

Two publications of the National Bureau of Standards are useful for their thermodynamic data. Circular 500, Selected Values of Chemical Thermodynamic Properties, 1952, is a vast compilation of very useful physical data, though it is not so up to date as Landolt-BSrnstein. Circular 510 and its supplements, Tables of Chemical Kinetics, Homogeneous Reactions (1951) is a critical compilation of data on rates and rate constants of homogeneous chemical reactions with evaluations and literature references. The Directory of Continuing Numerical Data Projects is a survey and analysis by the Office of Critical Tables (National Research Council Publ. 837, 1961) which reviews the American Petroleum Research Project on hydrocarbons, the Chemical Kinetics Data Project, Selected values for the thermodynamic properties of metals and alloys, and Selected values of chemical thermodynamic properties and other projects. 

Prout s hypothesis that the atoms of all elements were composites of hydrogen. Further, Mendeleev was particularly fond of emphasizing that smooth curves should not be drawn through the points representing numerical data on the elements, since such curves would imply continuity instead of strict individuality. 

Figure 1 graphically depicts the numerical data relevant to our application listed by Lundberg et al. Different sets of curves off vs. X are provided for individual values of d /d0. Discrete data were provided in the numerical tables of the original work to produce the continuous traces in Figure 1, a cubic spline fitting was used. 

Fig. 14. (Continued).The localized EDM for the M = toluene-[V205] system, numbered in accordance with the isolated reactant IDM they resemble the most (see Figs. 2 and 8a). The usual phase convention (pjEDM = dN/dpa > 0 has been adopted. Part a groups the EDM associated with the (V2Os) cluster, X = A, and Part b corresponds to toluene, X = B. The numerical data above each diagram report the number of IDM giving the maximum projection on the EDM in question, M iE0M), followed by its resolution into reactant contributions w (EDM) and w (EDM), in parentheses. The bottom numbers include t ).,., w.CT, ngTjEDM) (second row, in parentheses), and fJT(EDM)...

Fig. 31. (Continued). The complementary reactive (delocalized) IRM for the molecular adsorption (Part A) and transition-state (Part B) chemisorption complexes of Fig. 30. The numerical data are reported in the same order as in Fig. 21. The CT parameters have been calculated for the assumed water (base, B) - rutile (acid, A) electron transfer...

The plant is controlled by a process computer (ABB-Hartmann and Braun) and equipped with numerous data-collecting instruments. Surveillance is carried out by continuous analysis of the room air as well as by explosion-limit controls. The pyrolysis gas is analyzed automatically by a gas chromatograph. All data obtained are registered to enable calculation of energy and mass balances. Some basic components are continuously monitored by infrared spectroscopy, i.e. ethylene in the pyrolysis gas, sulphur dioxide and oxygen in the exhaust gas. 

The expression you just typed is called a formula. In Excel, formulas begin with an equals sign [ = ] followed by the desired numerical expression. Notice that the difference between the contents of cell B3 and cell B4 is displayed in cell B5. Now continue entering data until your spreadsheet looks like the one in Figure 3-4.

The evaluation, maintenance and manipulative functions discussed above are peculiar to numeric data. Continuous updating, in particular, is very easy to carry out on computer files but is very difficult with the conventional printed data handbooks. We can therefore expect the former to gradually replace the latter over the next few years, provided only that access to computerised data banks can be made as readily and cheaply available. 

The benefits that have been realized transcend the results of geographic exploration of the continent and the acquisition of a large body of numerical data on subjects that range across the entire spectrum of science. The most far-reaching consequence of the IGY and its aftermath is the harmonious working relationship that has developed among the nations that continue to participate in Antarctic research in accordance... 

The quantitative experiment results in numerical data consisting of measurements related to the characteristics of product or process under consideration. The variables associated with these characteristics are quantitative variables. The measured property may be continuous, which may take any value limited only by the precision of the measuring device, or discrete, in which case it takes only integer values resulting from counting. 

It is very difficult for human to memorize the numerical data points but tries to memorize the general behavior fxmction of data pxrints. In addition, for modeling, the human converts a MIMO (Multi Inputs - Multi Outputs) system to some SISO (Single Input - Single Output) systems and then human tries to find the general behavior function in each SISO system and the effects of other inputs are considered as the deviation of data pwints around of the general behavior function. In addition, human can save the data points on a continuous path... 

Raster Data Digital information stored on a grid of pixels assigned a particular value. These data sets create numeric data well suited for the storage of continuous data collected over large regions.
