Parallel algorithms for proximity problems
(1990)
Proximity problems deal with "closeness" of points in a finite set in k-dimensional space under some distance metric L (subscript p). These problems arise in many applications such as pattern recognition, wire routing, and ...
The effect of teacher written positive comments on the locus of control of fourth and fifth grade spelling students
(1990)
This purpose of this study was to examine the effects of teacher written comments of encouragement and praise on the locus of control of fourth and fifth grade spelling students. Two hundred and twenty-eight students from ...
Enzymes in organic synthesis : aldolase-catalyzed reactions for the synthesis of unusual sugars
(1990)
Several aspects of the use of enzymes in organic synthesis have been explored. Fructose-1,6-diphosphate aldolase (FDP aldolase) is available commercially and has been cloned and overexpressed in E. coli. Both aldolases ...
Investment and expectations in the U.S. farm sector
(1990)
The objective of this study was to analyze the interrelationship between expectations patterns and investment behavior of producers in the U.S. farm sector. A major problem confronting U.S. farm sector is overinvestment ...
Macroeconomic implications of the government budget identity : the case of a predetermined fiscal deficit and a pure nominal interest rate peg
(1990)
We consider the restrictions that the government budget identity places in an economy with rational expectations and, in particular, the case in which the fiscal authorities predetermine the conventional government deficit ...
Modeling the effects of refrigerant charging on air conditioner performance characteristics for three expansion devices
(1990)
An experimental and analytical study concerned with the off-design refrigerant charging of air conditioners is presented. A series of experiments were conducted to characterize the effects of refrigerant charge and type ...
Norm closed bimodules of nest algebras
(1990)
Let N be a complete nest in a separable Hilbert space H, and let algN be the nest algebra related to N. We obtain necessary and sufficient conditions for B(H) to be principally generated as a norm-closed bimodule of algN. ...
A three-dimensional viscous flow model of stator/rotor interaction in turbomachines
(1990)
The current numerical model takes into account the full three-dimensionality and cyclic fluctuations of the flow variables in a turbomachinery stage. The cyclic fluctuations are the result of circumferential irregularities ...
An investigation into the effects of damage on the stresses in a composite laminate
(1990)
A general constitutive framework based on continuum damage mechanics with constraints imposed by thermodynamics for composite laminates is presented. Several methods for the calculation of matrix crack and delamination ...
Dietary mineral requirements of Penaeus vannamei : evaluation of the essentiality for thirteen minerals and the requirements for calcium, phosphorus, copper, iron, zinc, and selenium
(1990)
The dietary requirements for calcium, phosphorus, Ca:P ration, copper, iron, zinc and selenium as well as the effects of phytate on zinc bioavailability to juvenile P. vannamei were evaluated utilizing a casein/gelatin ...
