Array number

For a given type of x-values distribution, the size of the x-values array (number of blocks ra, ) plays approximately the same role as the number of scans N. Theoretically, the relative precision of any relaxation rate estimate is proportional to the square root of both and N. This, of course, presumes that Ub is anyway large enough to carry out the analysis. For example, values as small as 4 may be sufficient in mono-exponential cases, while continuous distributions spreading over several orders of magnitude require a logarithmic distribution of x-values and Ub values of over 100.

Inside the array, numbers 1 and 2 label the low and high levels of the factors. However, each of the rows indicates the factor-level combination to be applied to the specific experimental unit. Note that in each column, both levels 1 and 2 appear an equal number of times. It is also true for rdl combinations (1,1), (1,2), (2,1) (2,2) appearing in any two columns. Hence the name orthogonrd array. ... 

Let us now consider a finite x infinite array as shown in Fig. D.2 consisting of 2Q + stick arrays. The current in the reference elements are denoted Iq. Writing Ohm s Law for the reference element in stick array number 0 yields... 

Values for sYiribl and AA will be read into the computer, each one subscripted with an array number I. Note that the variables symbl and aa had to have been put into the file using a write l statement having exactly the same format as the read 1 statement. When the file runs out of variables, the last array number will be designated N. Now it will be known how many values of symbl and aa were in the file. 

Other limitation for the spatial resolution can be found in the detector. A limited number of pixels in the camera array can be a reason for pure resolution in the case of a big field of view. For example, if field of view should be 10 by 10 nun with camera division 512x512 pixels the pixel size will be approximately 20 microns. To improve the relation of the field of view and the spatial resolution a mega-pixel sensor can be used. One more limitation for the spatial resolution is in mechanical movement (rotation) of the object, camera and source. In the case of a mechanical movement all displacements and rotations should be done with accuracy better than the spatial resolution in any tested place of the object. In the case of big-size assemblies and PCB s it is difficult to avoid vibrations, axle play and object non-planarity during testing.

Often a seven-segment array is sufficient for TN devices where numbers are displayed 11131. The limited number c switched means that each can be addressed directly. However, dot matrix or VGA displays with large numbers of p to create alphabetical characters (not just in the Roman alphabet, but also more complex symbols such as those in C...

A column matrix is an ordered set of numbers therefore, it satisfies the definition of a vector. The 2x1 array... 

The periodic table is the most important chemistry reference there is. It arranges all the known elements in an informative array. Elements are arranged left to right and top to bottom in order of increasing atomic number.. This order generally coincides with increasing atomic mass... 

The array detector (collector) consists of a number of ion-collection elements arranged in a line each element of the array is an electron multiplier. Another type of array detector, the time-to-digital converter, is discussed in Chapter 31. 

The major advantage of array detectors over point ion detectors lies in their ability to measure a range of m/z values and the corresponding ion abundances all at one time, rather than sequentially. For example, suppose it takes 10 msec to measure one m/z value and the associated number of ions (abundance). To measure 100 such ions sequentially with a point ion detector would necessitate 1000 msec (1 sec) for the array detector, the time is still 10 msec because all ions arrive at the same time. Therefore, when it is important to be able to measure a range of ion m/z values in a short space of time, the array detector is advantageous. 

An array ion collector (detector) consists of a large number of miniature electron multiplier elements arranged side by side along a plane. Point ion collectors gather and detect ions sequentially (all ions are focused at one point one after another), but array collectors gather and detect all ions simultaneously (all ions are focused onto the array elements at the same time). Array detectors are particularly useful for situations in which ionization occurs within a very short space of time, as with some ionization sources, or in which only trace quantities of a substance are available. For these very short time scales, only the array collector can measure a whole spectrum or part of a spectrum satisfactorily in the time available.
