Isobaths.zip contains ASCII files of isobath polygons in form of blank files (.bln) for the depths of 10,20,30,40,50,60,70,80,90,100,120,140,160,180,200,250,300, and 400 m compiled from the digital bottom topography of Seifert et al, (2001 Section 20.2,5), Each file contains several polygons, starting with the particular number of polygon vertices, followed by its sequence of (Ion, lat) coordinate pairs. 

The surface area of the inner Baltic Sea, bordered at the bottlenecks of the Danish Straits, amounts toA = 382 486 km if computed using RANGS shorelines on the WGS-84 ellipsoid (Hagen and Feistel, 2001), Equation 20.10. The absolute maximum uncertainty of the sea surface is about 10%, while the likely uncertainty lies in the range between 0.1% and 1 %. The length of the border line enclosing this surface area computed at the RANGS resolution of about 100 m is about L = 70 000 km. 

In WGS-84, the World Geodetic System 1984 (NIMA, 2000), the earth model is given by a rotational ellipsoid with the (equatorial) semimajor axis, a = 6 378.137 km, and the (polar) semiminor axis, b = 6 356.752 3142 km, corresponding to anumerical eccentricity, e, given bye = —b ia = 6.694 379 990 14x 10 . At the longitude 2 and the latitude p, the zonal distance element, AL, on the terrestrial surface is

Accuracy, however, in biomolecular trajectories, must be defined somewhat subjectively. In the absence of exact reference data (from experiment or from an analytical solution), the convention has been to measure accuracy with respect to reference trajectories by a Verlet-like integrator [18, 19] at a timestep of 1 or 0.5 fs (about one tenth or one twentieth the period, respectively, of the fastest period an 0-H or N-H stretch). As pointed out by Deufihard et al. [20], these values are still larger than those needed to...

The thermocouple reference data in Tables 11.55 to 11.63 give the thermoelectric voltage in millivolts with the reference junction at 0°C. Note that the temperature for a given entry is obtained by adding the corresponding temperature in the top row to that in the left-hand column, regardless of whether the latter is positive or negative. 

Interestingly, if the original comparison of the spectrum from the reference compound with stored m/z data for that compound reveals discrepancies, the stored reference data are updated before the computer goes on to acquire data from the unknown compound. In this mode, the computer is not used simply to acquire and manipulate data but is also used to make decisions...

Since IR spectra are essentially due to vibrational transitions, many substituents with single bonds or isolated double bonds give rise to characteristic absorption bands within a limited frequency range in contrast, the absorption due to conjugated multiple bonds is usually not characteristic and cannot be ascribed to any particular grouping. Thus IR spectra afford reference data for identification of pyrimidines, for the identification of certain attached groups and as an aid in studying qualitatively the tautomerism (if any) of pyrimidinones, pyrimidinethiones and pyrimidinamines in the solid state or in non-protic solvents (see Section 2.13.1.8). 

The tests for insulation resistance and dielectric loss factor should, however, be carried out on a completed machine also with formed coils to establish reference data for field tests, as noted in Section 9.6. However, these tests on a completed machine with formed coils do not monitor the process quality of insulation.

Fragility testing This is a proprietory test to provide future reference data about an object, on its worthiness to operate under certain seismic conditions. When no seismic requirements are defined by the manufacturer the object is tested for its optimum capability. 

Information about this splendid compilation came to me from a chemist, Robert Weast (1985), who was editor from 1952 until 1988... 37 years He also informed me that the creation (jointly by the American Chemical Society and the American Institute of Physics) of the Journal of Physical and Chemical Reference Data, which began publication in 1972, was encouraged by the results of a survey which indicated how widely the Rubber Bible was used. Weast describes this journal as a truly outstanding source of critically evaluated data . In saying this, he underlined the crucial role of editors and contributors critical judgment in selecting data for such compilations. David Tide, the editor of the journal, in 1989 succeeded Robert... 

Once the question of assigning weights for the reference data has been decided, the fitting process can begin. It may be formulated in terais of an error function. 

Validation of a force field is typically done by showing how accurately it reproduces reference data, which may or may not have been used in the actual parameterization. Since different force fields employ different sets of reference data, it is difficult to compare their accuracy directly. Indeed there is no single best force field, each has its advantages and disadvantages. They perform best for the type of compounds used in the parameterization, but may give questionable results for other systems. Table 2.6 gives some typical accuracies for AH( that can be obtained with the MM2 force field.

Gradient corrected methods usually perform much better than LSDA. For the G2-1 data set (see Section 5.5), omitting electron affinities, the mean absolute deviations shown in Table 6.1 are obtained. The improvement achieved by adding gradient terms is impressive, and hybrid methods (like B3PW91) perform almost as well as the elaborate G2 model for these test cases. For a somewhat larger set of reference data, called the G2-2 set, the data shown in Table 6.2 are obtained. 

The schedule sheet which summarizes the key reference data for a particular class of equipment such as pumps, but contains no process data. The latter type is prepared for job coordination with and in the various departments, i.e., engineering, construction, purchasing, production. It primarily serves for the construction period but, of course, does have lasting cross-reference value. 

Comparative analysis directly compares two or more data sets in order to detect changes in the operating condition of mechanical or process systems. This type of analysis is limited to the direct comparison of the time-domain or frequency-domain signature generated by a machine. The method does not determine the actual dynamics of the system. Typically, the following data are used for this purpose (1) baseline data, (2) known machine condition, or (3) industrial reference data. 

The baseline data set must be updated each time the machine is repaired, rebuilt, or when major maintenance is performed. Even when best practices are used, machinery cannot be restored to as-new condition when major maintenance is performed. Therefore, a new baseline or reference data set must be established following these events. 

A series of baseline or reference data sets should be taken for each machine-train included in a predictive-maintenance program. These data sets are necessary for future use as a reference point for trends, time traces, and FFT signatures that are collected over time. Such baseline data sets must be representative of the normal...
