Alpha/beta value

Later we will see that the nonlinearity is not a problem in use. It is not possible here to go into all the details of NTC theory for temperature coefficient alpha, beta value, self-heating effects, thermal time constant, thermal dissipation constant, stability, and reliability. Good information can be found elsewhere [1, 2] and in NTC manufacturers handbooks, catalogs, or web pages [3-10]. 

N with mixed nitric-sulfuric acid. It has been suggested that isotrotyl consists of addition compounds of the isomers instead of free isomers. Since the alpha, beta and gamma compounds are practically of the same value as explosives, this low-melting explosive (isotrotyl) was found to be useful as a constituent of blasting explosives, such as Roburite, Bellite etc. It was also used to lower the melting points of other explosives, eg TNX or PA... 

The order of sensitivity of the polymorphs of HMX may be summarized as follows delta >gamma > alpha >beta. The range of values obtd using an Explosives Research Laboratory, Bruceton,... 

From the information values in figure 1 it is possible to observe that in general the prediction in all alpha and alpha+beta classes has a greater success than for all beta and alpha/beta classes. Also it shows a greater variability between predictive accuracies of the methods among each other as well as between the fold classes individually. 

The alpha-beta transition is ill-defined. There are many conflicting studies as to the value of the transition temperature and the value and sign of the derivative (dT/dP) for this transition. We adopt = 1527 25 K based on the...

Pleuro-pulmonary solitary fibrous tumors A clinicopathologic, immunohistochemical, and molecular study of 88 cases confirming the prognostic value of de Perrot staging system and p53 expression, and evaluating the role of c-kit, BRAF, PDCFRs (alpha/beta), c-met, and ECFR.

The results showed that the participants became less vigilant and reported more TUITs over the course of the session. The measures of absolute power in the alpha, beta, and theta frequency bands did not show any differences across the pre-TUIT and post-TUTT intervals. However, significant increases fiom pre-to post-TUIT in the value of two of the power band ratios, beta/(alpha +theta) and beta/alpha, were observed for all parietal lobe sites (Pz, P3, and P4). Cunningham etal. (in press) concluded power band ratios may provide a more sensitive measure of fluctuations in attention than more Iradilional measures of absolute power within any individual frequency band. 

The traditional methods of CCF modeling when probability of CCF events is derived from the component failure probability by the means of specific factors (ALPHA, BETA, MGL, etc.) could hardly work as the biggest problem is to establish the basic software fault probability. Moreover values of parameters for particular combinations (couples, triples, etc.) would be significantly different from. .traditional" ones (Mosleh, A., 1993) as the portion of CCF prob-abihty on the single train software probability would be much higher. 

Whereas Hunter derived his alpha, beta chromaticity directly from C.I.E. quantities, Adams (1942, 1943) developed a chromatic value space and subsequently derived from it a chromatic valence space. He first modified the tristimulus values so that for illuminant C... 

In the quantitative approach, alpha and beta values representing failure mode ratio and failure effect probability, respectively, are necessary. Alpha represents the probability, expressed as a decimal fraction, that the given part or item will fail in the identified mode. Beta represents the conditional probability that the failure effect will result in the identified criticality classification, given that the failure mode occurs. In the quantitative approach the value of each failure mode criticality number is defined as ... 

Exceeding Composition Limits. As for all alpha-beta alloys, excessive amoimts of aluminum, oxygen, and nitrogen can decrease ductilily andfi acture tou mess. Excessive amounts of beta stabilizers (molybdenum and vanadium) affect the stability of the alloy and increase its heat treatability, therefore making control of properties more difficult. Excessive impiuity levels may raise yield strength above maximum permitted values or decrease elongation or reduction in area below minimum values. 

Gr. aktis, aktinos, beam or ray). Discovered by Andre Debierne in 1899 and independently by F. Giesel in 1902. Occurs naturally in association with uranium minerals. Actinium-227, a decay product of uranium-235, is a beta emitter with a 21.6-year half-life. Its principal decay products are thorium-227 (18.5-day half-life), radium-223 (11.4-day half-life), and a number of short-lived products including radon, bismuth, polonium, and lead isotopes. In equilibrium with its decay products, it is a powerful source of alpha rays. Actinium metal has been prepared by the reduction of actinium fluoride with lithium vapor at about 1100 to 1300-degrees G. The chemical behavior of actinium is similar to that of the rare earths, particularly lanthanum. Purified actinium comes into equilibrium with its decay products at the end of 185 days, and then decays according to its 21.6-year half-life. It is about 150 times as active as radium, making it of value in the production of neutrons. 

Half-life is the time taken to decrease the concentration of a drug to one-half its original value. There may be several phases in the elimination, and the most common is the so-called beta-phase. Alpha-phase is a distribution phase and gamma-phase is the terminal phase when the drug is finally leaving the tissues.
