Relative Efficiency of External Prestressing
Journal of Structural Engineering, 1995In this paper, the efficiency of tendon profiles is examined for the internal and external prestressing of statically indeterminate structures. The statically indeterminate component of the total prestressing moment is shown to be significant for both parabolic and linear tendon profiles.

Asymptotic Relative Efficiency
1981In any given inference situation, many statistical procedures may be available, both parametric and nonparametric. Some measure of their relative merits is needed, especially as regards their performance or operating characteristics. For instance, a comparison of the power functions of various tests of the same (or essentially the same) hypotheses ...

Relative efficiency in survival analysis
Journal of Chronic Diseases, 1983The relative efficiency of analyzing the times to death vs the proportion surviving a fixed period when comparing the survival experience of two groups is examined. The two methods are compared with respect to trial duration for either fixed patient entry or cost and with respect to cost for fixed duration. When the ratio of median survival is equal to

Relative Packing Efficiency in Hydrates
Journal of Chemical & Engineering Data, 2009We define two parameters, Πice and Πparent, estimated from hydrate and parent volumes, to be a measure of the efficiency of the packing of molecules in a hydrate compared on the one hand to that of idealized solid ice and on the other to the parent molecule from which the hydrate is derived.

Relative Efficiency of Voting Systems
SIAM Journal on Applied Mathematics, 1983Most comparisons of voting systems have focused on the outcomes of the elections and on the propensity of the systems to elect Condorcet winners. In this analysis, the emphasis is on the voters and the effectiveness of sincere voting on their part. The relative efficiency of sincere voting is defined to be the ratio of the maximum expected “gain” (in ...

Relativity and Efficient Taxation
Southern Economic Journal, 1987Research by Frank [3; 4; 5], Van de Stadt, Kapteyn and Van de Geer [7], Layard [6], and Easterlin [2] suggests that the tax consequences of Duesenberry's relative income hypothesis [1] deserve investigation. The "relativity" hypothesis contends that when one person increases his income, he imposes utility losses on others. If the hypothesis is correct,

Unions, Relative Wages, and Economic Efficiency
Journal of Labor Economics, 1983The ability of unions to raise the wages of their members above the wages of similar but nonunionized workers is well documented. This paper examines empirically the implications of that wage differential for resource allocation and economic efficiency.

Relative Efficiency of International Airlines
Anais do(a) 3rd Eu International Conference on Industrial Engineering and Operations Management, 2019In this paper the results are published of a post-doctorate research done at the Brazilian Aeronautics Technological Institute (ITA) in 2006. The purpose of this paper is to evaluate and to discuss the relative efficiency of the main Brazilian carriers in the period from 2000-2006 by comparing their operational and relative efficiency with ...

Relative Efficiency of Intermunicipal Provision
1998The intermunicipal arrangement is one of the opportunities municipalities can use to redece their budget problems. Intermunicipal arrangements, privatizing activities, such as contracting out, and straightforward budget cuts were popular instruments used in response to the fiscal squeeze during the ‘eighties. It is conceivable that the establishment of

Relative efficiency of radiation sources for photopolymerization
Odontology, 2009The aim of this study was to evaluate the characteristics of new-generation light-emitting diode (LED) units in comparison with the conventional tungsten-halogen, plasma arc, and first-generation LED units reported in our previous study. The irradiance of light from new-generation LED units, the temperature rise of the bovine enamel surface, and the ...
