Orthogonal Array and Virtualization as a Method for Configuration Testing Improvement
2009 First IEEE Eastern European Conference on the Engineering of Computer Based Systems, 2009Combinatorial testing methods are often applied in cases of configuration testing. Good practice points to the simultaneous application of combinatorial testing and virtualization. Virtualization, in the process of testing, is based on setting the necessary environment to multiple virtual machines, which run on one computer or in smaller groups of ...

Orthogonal Frontiers and Alternative Mean‐Variance Efficiency Tests
The Journal of Finance, 1987ABSTRACTThis paper catalogues properties of minimum norm orthogonal portfolios: portfolios which minimize a quadratic objective function and have returns uncorrelated with those of a candidate portfolio that is not mean‐variance efficient. The analysis shows that the dollar versions of these portfolios correspond to estimators of zero beta rates based ...

A new method testing the orthogonality of different protecting groups
Carbohydrate Research, 2015A new test was elaborated to identify a new set of orthogonal protecting groups. With the developed method eight different protecting groups were tested under various deprotection conditions and the complex reaction mixtures were analysed by HPLC. The developed method allows for quick identification of orthogonality using simple model structures.

Orthogonal exploration of the search space in evolutionary test case generation
Proceedings of the 2013 International Symposium on Software Testing and Analysis, 2013The effectiveness of evolutionary test case generation based on Genetic Algorithms (GAs) can be seriously impacted by genetic drift, a phenomenon that inhibits the ability of such algorithms to effectively diversify the search and look for alternative potential solutions. In such cases, the search becomes dominated by a small set of similar individuals

Manufacturing Process of Packaging Products by Orthogonal Test
Applied Mechanics and Materials, 2013For most plastic packaging products, injection molding is the most convenient, simple, widely applicable, especially for those thin, complex structure, smooth surface, and small moulds. Overdependence on experience, it is difficult to quickly design excellent products with short production cycle.

On Dependent Tests from a Non-Orthogonal Design
Journal of the American Statistical Association, 1966Abstract This paper illustrates, through a special case, an effect of non-independent numerators on F-test's in an analysis of variance. Symmetrical balanced incomplete block designs are considered with “blocks” a random effect and no interaction. The joint density of the adjusted sums of squares is determined under the null hypothesis of no treatment ...

Generalized orthogonal contrast tests for homogeneity of ordered means
Canadian Journal of Statistics, 1999AbstractSeveral procedures have been proposed for testing equality of ordered means. The best‐known of these is the likelihood‐ratio test introduced by Bartholomew, which possesses generally superior power characteristics to those of its competitors. Difficulties in implementing this test have led to the development of alternative approaches, such as ...

Well Test Simulation using Orthogonal Collocation
SPE Middle East Oil and Gas Show and Conference, 2009Abstract Welltesting is a flow of slightly compressible fluids in a porous media which is characterized by a set of nonlinear partial differential equations. Their solution is normally achieved analytically using Laplace transform or numerically through the use of numerical inverting methods of the Laplcace transform like Stehfest and ...

Orthogonal test for preparing genipin with enzymolyzed geniposide
China Journal of Chinese Materia Medica, 2012OBJECTIVE To optimize the process for preparing genipin with enzymolyzed geniposide by an orthogonal experiment. METHOD The optimal enzymolysis process was selected by an orthogonal experiment, with the concentration of geniposide as the index as well as enzyme quantity, pH of enzymolysis solution, enzymolysis time and enzymolysis temperature as ...
