Reliability parameter

RDB, thej eliability database module, creates a user-defined database or retrieves data from the IAEA generic reliability database. The design facilitates RDB development for components, human actions, initiating events and the attributes of components. Component unavailabilities can be calculated from the database of reliability parameters using 10 types of predel mcd leliabiliiv models.

Computerized Aggregate of Reliability Parameters (CARP) A computer code developed by SAIC to aggregate data sets into a single generic set determine uncertainty bounds (5th and 95th percentiles) fit raw data to statistical distributions and print reports documenting determinations made. 

Even though the load carrying capacity and friction behavior are apparently of interest to the authors, they are not presented here because no general law can be constructed if there are no practically reliable parameters presented. This remains to be done in our further research. 

The determination of the electronic structure of lanthanide-doped materials and the prediction of the optical properties are not trivial tasks. The standard ligand field models lack predictive power and undergoes parametric uncertainty at low symmetry, while customary computation methods, such as DFT, cannot be used in a routine manner for ligand field on lanthanide accounts. The ligand field density functional theory (LFDFT) algorithm23-30 consists of a customized conduct of nonempirical DFT calculations, extracting reliable parameters that can be used in further numeric experiments, relevant for the prediction in luminescent materials science.31 These series of parameters, which have to be determined in order to analyze the problem of two-open-shell 4f and 5d electrons in lanthanide materials, are as follows. 

Lipophilicity is not a reliable parameter for classifying the CNS activity of the particular set of compounds used in the study. 

The use of enantiomers as additional markers for taxonomic characterization of aromatic plants may be very helpful. The differences in the enantiomeric distribution of trans- and cis- sabinene hydrates in two Origanum species enable the species to be distinguished in spite of their similar essential oil compositions. A further study on the natural variation of the enantiomeric composition within a wild population may be carried out in order to examine the stability in a taxon (including the possible presence of chemotypes). The enantiomeric ratio of essential oil components is a reliable parameter for assessing quality because it may be indicative of adulteration, contamination, aging, shelf life, technological process and the botanical source of a specific chiral compound. ... 

In l-chloro-l,2-dimethylcyclobutane and l-bromo-l,2-dimethylcyclobutane the H-2 and 2-methyl protons absorb at higher frequencies (larger <) values) if they are cis to the halogen atom. Analogous trends have been observed for H-3 and the 3-methyl protons in l-chloro-1,3-dimethylcyclobutane and l-bromo-l,3-dimethylcyclobutane but here the differential shifts are smaller464. Overall, H chemical shifts are not very reliable parameters for the differentiation of diastereomers. 

Several authors have pointed out that the urinary excretion of hippurate is a poor indicator of exposure to toluene at 200 ppm [760 mg/m ] or lower (Jonai Sato, 1988 Too et al., 1991 Pierce et al., 1996). Therefore, data on ethnic differences in hippurate or cresol excretion in urine at these low exposure levels (e.g., Inoue et al., 1988) are of doubtful significance. Toluene level in expired air may be a more reliable parameter (Foo et al., 1991). Although at the level of the individual, data on urinary hippurate cannot be reliably used to estimate low toluene exposures, they can be used at the group level to establish whether at a certain location the toluene exposure remained below a particular threshold (Lauwerys, 1983). 

Chung model of neuropathic pain Nerve injury in rats is induced by a tight ligation of the root of the spinal nerve at L5-L6. Animals show hyperalgesia and allodynia similar to the Bennet model. Tactile allodynia, measured with von Frey hairs, is the most reliable parameter of pain intensity in this model (Kim and Chung, Pain 1992, 50, 355-363). 

For 3-methyl- and 3-ethyltetrahydro-l,3-thiazine, reliable parameters on which to base an estimate of the position of conformation equilibria 309 310 have recently become available287 based on 13C-NMR parameters (Table XXIII). For the N-methyl derivative, the AG° for the equilibrium 309 (R = Me) 310(R = Me) of —0.7 kcal mol-1 shows a greater axial preference for the methyl group than in N-methyltetrahydro-l,3-oxazine(AG° — 0.1 kcal mol-1). The introduction of a 2-alkyl group increases significantly the predominance of the N-alkyl conformer (Table XXIII). 

It may be emphasized here that the h-factor has become the more reliable parameter in spite of a less marked effect since with the recent photon-correlation spectroscopy, translational diffusion coefficients can be measured with a high accuracy and over the whole molecular weight range, from the monomer up to the largest molecular weights. 

Protein hydrophobicity has been most frequently expressed as relative values measured by the methods used, since no standardized unit has ever been established. These relative values are incorporated directly into correlation studies with protein functions. Therefore, the correlation coefficient of a measured functionality against the counterpart predicted from the measured hydrophobicity is the most reliable parameter to use for comparing different methods for hydrophobicity measurement. 

In order to solve these problems, it is very important and useful to clarify band structures of group-III nitrides and their QW structures and also to obtain their band structure parameters. In this Datareview, definitions of band structure parameters and available data on them for GaN and AIN are given. The data are mainly about theoretical results with first-principles band structure calculations within the local density functional approximation (LDA). They are compared with currently available experimental results. Note that the LDA calculation grossly underestimates a bandgap and that it gives almost zero bandgap for InN. Such a calculation is unlikely to yield reliable parameters for InN, especially effective masses. Therefore, the band structure parameters of InN are not given in this Datareview. 

The specific surface areas, 5bet, as estimated from the BET theory for the pure materials and for each mixture are given in Table 1. This method consists in determining the specific surface area from the monomolecular layer volume of the adsorbed nitrogen. It is clearly seen on Figure 2a that the specific surface area, 5 bet, is a linear function of the mixing proportions. As discussed in the introduction this observation suggests that the BET surface is a reliable parameter.

The icteric phase lasts for some 2 to 6 weeks. Laboratory parameters become completely normalized after 4 to 6 months. Normalization of the serum bile acid is also deemed to be a reliable parameter of recovery. The regression phase is often characterized by pronounced diuresis. (56, 76, 113)... 

In summary, the literature data suggests that the hydrogen bond basicity is still the most reliable parameter to which reaction outcomes can be correlated. The effect of the cation is often not easily predicted, due to a delicate interplay specific to each anion and cation combination in the pure ionic liquid, which exhibits unique interactions when a solute is added. 

The gas exposure slightly affects the sp component of the carbon network. Since these changes are not relevant as for the C band, can be considered a reliable parameter when following the sp component evolution.
