Data systems, high-speed

A review of the data and high-speed movies taken of the tests indicated that smoke may have prevented IR detectors from seeing the fire soon enough to prevent flame propagation. A detector was added within the hopper, and this sprinkler system arrangement effectively prevented propagation in three consecutive trials. 

The entire reconstruction in 3D of an object is quite time consuming at present. Techniques are being developed, howevei to speed up the measurement process, combining fast detector systems, high-speed data networks, and parallel computing systems. 

Transamination between oxo- and amino-acids is one of the enzymatic reactions that can be duplicated in metal ion model systems (1-4). The reactive intermediates appear to be "mixed complexes in which it is thought the ligands are condensed as Schiff bases. Recently, ways of applying pH-titration techniques to these systems and analyzing the data using high speed computers have been proposed (5). This earlier study (5) which concerned the Ni(II)-pyruvate-glycinate system has been extended to an examination of the Ca(II), Mn(II) and Zn(II) systems at 25 . An attempt was also made to obtain the heats and entropies of formation of the Mn(II), Ni(Il) and Zn(II) complexes from additional titrimetric data at 10 and 40 . 

A total analysis of high-speed rotating equipment requires a eomplex blend of performanee and vibration data. The trend toward total analysis is growing with the problems of an energy shortage and the need for maximum plant utilization. Performanee analysis is essential in the effieient utilization of turbomaehinery and, when eoupled with vibration analysis, is an unbeatable tool as a total diagnostie system. 

In quadrupole-based SIMS instruments, mass separation is achieved by passing the secondary ions down a path surrounded by four rods excited with various AC and DC voltages. Different sets of AC and DC conditions are used to direct the flight path of the selected secondary ions into the detector. The primary advantage of this kind of spectrometer is the high speed at which they can switch from peak to peak and their ability to perform analysis of dielectric thin films and bulk insulators. The ability of the quadrupole to switch rapidly between mass peaks enables acquisition of depth profiles with more data points per depth, which improves depth resolution. Additionally, most quadrupole-based SIMS instruments are equipped with enhanced vacuum systems, reducing the detrimental contribution of residual atmospheric species to the mass spectrum. 

Finally, in this Introduction, it is worthwhile to reproduce one of the several current definitions, in the Oxford English Dictionary, of the word simulate To imitate the conditions or behaviour of (a situation or process) by means of a model, especially for the purpose of study or training specifically, to produce a computer model of (a process) . The Dictionary quotes this early (1958) passage from a text on high-speed data processing A computer can simulate a warehouse, a factory, an oil refinery, or a river system, and if due regard is paid to detail the imitation can be very exact . Clearly, in 1958 the scientific uses of computer simulation were not yet thought worthy of mention, or perhaps the authors did not know about them. 

This method is also being used at the Hines VA CSPCC for a number of trials. It appears to be superior to the paper data collection with centralized interactive data entry. It is not time consuming because data are entered with high-speed double-key data entry, which expedites processing of received forms and thus the accumulation of the master database. Another major advantage is that only one person is needed to run the system. 

However, flow generated by a cylinder rotating at high speed was subsequently used by others, and in particular by King and co-workers (K3, K4a), to demonstrate that dissolution and electrochemical corrosion may both be transport limited. The dependence of the mass-transfer coefficient on the rotation rate and on the diffusivity of the dissolving species was established by correlation of experimental data (see Table VII, System 43). 

Another data acquisition consideration is data file size. A high speed LC/MS data file can easily reach dimensions of 20 MB/min if maximal information is required and the detectors are set to broadest scan ranges and highest sampling rates without data reduction. LC/MS systems capable...
