Array address computation

At present, two problems persist for the clinical application of IR spectral imaging methods. One of them is the enormous size of the datasets. In order to image an entire lymph node section, about 5x5 mm2 in size, on the order of 200 x 200, or 40000, individual spectra are collected. Although the data acquisition presents little problem and could be performed with existing array detector-based spectrometers within a few minutes, the data reduction by HCA takes over a day, even when using powerful personal computers such as the 64 bit AMD processor in our laboratory. The situation will undoubtedly improve tremendously when true 64 bit, WINDOWS-based operating system will be available to address the enormous... [Pg.196]

It is more reliable to calculate the time-delays between the IP-packets during open session between AC and VC. In this case after session closing we will get two arrays of time-delays values time-delays between AC and VC (Mi) in forward direction and time-delays between VC and AC (M2) in back direction. Thus VC can receive the information about AC address or the address of the last intermediate computer. If the attack is carried out with direct connection to VC (Figure 1) then the values of time delays between the packets which goes from AC to VC will be approximately equal to the values of time delays between the packets that goes from VC to AC. [Pg.196]

An additional economical aspect is that, as the intermediate sums are generated, they replace the original data values (which are no longer required), thus restricting the computer-memory requirement to the N addresses needed for the data array plus approximately 4,000 other addresses for storage of the f.f.t. program. [Pg.53]

Knowles and Handy present an explicit formula for computing a string s address from a list of its occupied orbitals.109 They employ an auxiliary array defined according to... [Pg.229]

One of the more pressing questions that is asked of the proponents of the molecular computer has been and still is how to organize inherently disordered molecules into potentially useful arrays. It is obvious that solution-based systems - although very satisfying intellectually - are doomed to the realm of scientific curiosity unless they can be incorporated into useful, practical devices in which single, or collections of, molecules can be addressed without influencing each other. One route by which this objective can be achieved, and which corresponds to conventional silicon devices - at least at a conceptual level - is to immobilize the pertinent molecules onto a solid support and then to build up a framework around which the molecules can be addressed. [Pg.222]

Test this macro on an array of formulas, numbers, or text (i.e., one or more letters, words, or sentences). Observe thatitwill return the address range whether the cells involved are empty or not. It will return no information for the value or formula of an empty cell (but that it comes up empty-handed will stop neither the program nor the computer), and it obviously will not be able to distinguish between a value and a formula when a cell merely contains a number, or text. Still, where there is valid information to be had, the macro will read it properly, and the message boxes will report it. [Pg.383]
