The plans are useful for incentives in life testing of these equipments against one another during their constant failure-rate period. The theory and equations for the tables are developed and the related references are included. Three test plans are summarized.

Method-One is a nonparametric binomial sequential test and consists of three plans: A, B1, B2.

The results are useful for incentive plans and are fundamental in life testing of these equipments against one another, during their constant failure-rate period. The theory and equations for the tables are developed and the related references are included. Six test planis are summarized.

The viscosity of over 300 compositions including soda-lime glasses, borosilicates, glasses with high alkaline earth content, NIST glass viscosity standards, lead silicates, fluorosilicates, and phospho-silicates have been examined. Using multiple regression modeling, linear and multiplicative relations between the chemical composition and several properties, e.g. viscosity, thermal expansion, density, refractive index, electrical conductivity were developed. In this paper the modeling of the viscosity versus composition is discussed. The described relations have been found to link data of different authors and compositions into one global equation which (a) allows validation of glass property datasets, (b) quantifies the influences of glass components and component interactions, and (c) allows some conclusions regarding the nature of glass. The analysis so far makes it possible to estimate the viscosity isokoms at log( /Pa s) = 12.0 with an error of ±7 o C, at log( /Pa s) = 6.6 with an error of ±9 o C, and at log( /Pa s) = 1.5 with an error of ±17 o C.

Data were collected from 526 small businesses in 14 major cities using the Entrepreneurial Profile Questionnaire. Factor analysis showed environmental difficulties and growth intentions to be multifactor constructs, while intensity emerged as a single factor. A canonical correlation analysis found owner intensity to be significantly related to the three growth plan factors of technology improvement, resource aggregation, and market expansion. Among the difficulty factors, only lack of know-how and financing problems showed a significant relation to growth plans. Financing difficulties hindered technological improvement and resource aggregation, while know-how negatively affected market expansion. Other difficulty factors such as entry barriers, family-business role conflict, and ethnic prejudice were not among the predictors of growth plans. The article draws out the implications of these findings for government policy and for future research.

The results are useful for incentive plans and life-cycle costing applications, and are fundamental in the life testing of equipment, whether a consumer or industrial item, during the constant failure-rate period. The theory and equations for the calculations of the tables and plans are developed and discussed and the related references are included.
