We conducted an exploratory study of the detection of a sudden change of the field time series based on the numerical solution of the Lorenz system. First, the time when the Lorenz path jumped between the regions on the left and right of the equilibrium point of the Lorenz system was quantitatively marked and the sudden change time of the Lorenz system was obtained. Second, the numerical soluti...

The purposes of this study were 1) to establish the concurrent validity of the universal goniometer and the fluid-based goniometer and 2) to determine the intertester reliability of these two instruments. A correlational study was performed in which two testers used the universal goniometer and the fluid-based goniometer in measuring elbow range of motion in 30 healthy subjects. The fluid-based...

We analyzed the differences, by Student's t-test and ANOVA, between nurses and physicians from Portugal, Poland, Spain, and United Kingdom regarding their relationship with their work and organization. In total, 1,401 professionals answered the HSA-QHPR questionnaire. There are different levels of connection between physicians and nurses. The United Kingdom has the lowest levels of connection w...

METHOD: In the present study 18 Indian district level soccer players age between 18-25 years were conveniently selected from Birbhum district of West Bengal as subjects. To measure aerobic fitness, two different indirect methods of measuring VO2max were employed; these were Queens College test and 12 minutes Run-Walk test (Cooper Test). The data were analyzed by applying independent t-test to d...

There are few studies conducted on the short-term effects of land leveling on soil water holding capacity. The objectives of this study were to analyze the short-term effects of land leveling on the magnitudes, variances, spatial variability, and distributions of surface (0-20 cm) and subsurface (20-40 cm) soil properties of bulk density, field capacity, permanent wilting point, water holding c...

The two-sided Simes test is known to control the type I error rate with bivariate normal test statistics. For one-sided hypotheses, control of the type I error rate requires that the correlation between the bivariate normal test statistics is non-negative. In this article, we introduce a trimmed version of the one-sided weighted Simes test for two hypotheses which rejects if (i) the one-sided w...

Efficient crossover designs for comparing t test treatments to one control treatment with three periods is considered. Through this investigation and the characterization obtained for the A-optimal/efficient designs in the nearly entire class, the efficiency of a given design is evaluated and guidance for constructing highly efficient designs is provided.
