Methodology evolved

Digital control methodologies similar to the Elliott Digital System program evolved from successful and proven reliable high-speed air compressor management and control approaches. [Pg.196]

Functional analysis. The methodology enables eaeh part to be elassified as essential A parts or non-essential B parts. Given this awareness, redesigns ean be evolved around the essential eomponents, from whieh redueed part eount normally results. [Pg.305]

A discussion of this polymerization method would not be complete without mention of the development of specialized glassware utilized over the years. It has evolved from very elaborate, sophisticated, and specially designed glassware to fairly simple setups. Initially, elaborate break-seal technology was used to complete the entire polymerization process,143 similar to anionic polymerization methodology.17 Break-seal techniques were employed to fully understand many monomer structure-reactivity relationships these techniques are no longer needed. [Pg.439]

The methodology described In this paper has evolved over the past ten years but still remains very elementary It was developed to minimize the exceptional hazards associated with the design and Implementation of accelerated life tests Many accelerated life tests can be characterized as expensive failures, due to the use of poor experimental designs. Inadequate scientific and statistical expertise, and Insufficient peer review prior to Implementation The methodology outlined below Is Intended to reduce such failures ... [Pg.68]

This analytical methodology deduces the four photooxidative processes. The data on the total CO2 evolved from the samples were measured by gas chromatography and the isotopic C02 ( 6C02 and 4°C02) data by GC/mass spectroscopy. The rate constants of the two major photooxidative degradation processes at 25°C were deduced from h 18o2 per -(C H NO)- (i.e., to produce C02 product, t = 42 hr) at 196°C and the other from 02 per -(C H NO)- (i.e., to 2produce C02 product, t = 8 min) at 196°C. The rate constants of the former process was estimated as 1.10 x 10- 1 mole sec-- - and the latter as 1.03 x lO-- - 1 mole-- - sec-- -. The activation energies of these two processes were deduced as 10.8 kcal/mole for the former and 15.7 kcal/mole for the latter. [Pg.341]

Since the seminal contributions by Nugent and RajanBabu the field of reductive C - C bond formation after epoxide opening via electron transfer has developed at a rapid pace. Novel catalytic methodology, enantio- and stereoselective synthesis and numerous applications in the preparation of biologically active substances and natural products have evolved. In brief, a large repertoire of useful and original reactions is available. These reactions are waiting to be applied in a complex context ... [Pg.58]

Acids were an early exception to the no water rule. It was recognized that aqueous solutions of acids would inhibit swelling of clays and shales as well as dissolve any acid-soluble minerals contained in a formation. By 1933 commercial well stimulation with hydrochloric acid was of great interest. A whole separate methodology and treatment chemistry has since evolved around acidizing and fracture acidizing(54). Water emulsions, mainly emulsified acids, and gelled acids thickened with polymeric additives were applied early in the history of well treatment. [Pg.69]

Keeping the lesson of the above example in mind, we will explore three different dynamical possibilities below isolated evolution, where the system evolves without any coupling to the external world, unconditioned open ev olution, where the system evolves coupled to an external environment but where no information regarding the system is extracted from the environment, and conditioned open evolution where such information is extracted. In the third case, the evolution of the physical state is driven by the system evolution, the coupling to the external world, and by the fact that observational information regarding the state has been obtained. This last aspect - system evolution conditioned on the measurement results via Bayesian inference - leads to an intrinsically nonlinear evolution for the system state. The conditioned evolution provides, in principle, the most realistic possible description of an experiment. To the extent that quantum and classical mechanics are eventually just methodological tools to explain and predict the results of experiments, this is the proper context in which to compare them. [Pg.54]
