Orthogonal Test Algorithm on TD-SCDMA Network Optimization
2011 Seventh International Conference on Computational Intelligence and Security, 2011The Network optimization is one of the most important link during the TD-SCDMA network construction and maintenance. This paper is used orthogonal test algorithm to adjust the system constantly in order to ameliorate the operate quality of network, and improve the ability of absorbing telephone traffic.

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

Calculating cross-orthogonality with expanded test data
AIAA Journal, 1982Compatibility In general, math model dynamic degrees-of-freedom (DOF) will not be uniquely one-for-one with accelerometers placed upon the prototypes. Consequently, reduction of the math model will be required. If all accelerometers do not lie directly at math model DOF, this reduction will require more than one step.

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.

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 ...

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 ...

PLA test pattern generation with orthogonal transform
Records of the 1993 IEEE International Workshop on Memory Testing, 2002It is known that test pattern generation even for fixed structured realizations of digital circuits, i.e. PLAs is a NP-complete problem. With respect to the growing complexity of integrated circuits, this process has to be optimized to avoid large development and production cycles.

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 ...

Test for dispersion effects from orthogonal arrays
Computational Statistics & Data Analysis, 1989Abstract Location and dispersion effects from factors have been considered in the industrial experiments set up through orthogonal arrays for the purpose of improving industrial processes. Most procedure in the literature concentrate on identifying location effects.
