system evaluations were performed on 48 center pivots in different parts of saudi arabia. these systems, located on different farms in four different regions of the country, namely: riyadh, jouf, qassim and eastern regions, were evaluated to study the effect of lateral configuration on water application uniformity as regards the original vs. modified laterals. lateral configuration modification...

We propose a way to construct consistent generalizations of the Cram er-von Mises test on the line, and the Watson U 2 n test on the circle, based on classes of partitions invariant under various group actions. The framework developed extends our earlier work generalizing the Kolmogorov-Smirnov and Kuiper goodness-oft tests, and provides a conceptually unifying description. Many goodness-oft te...

Classes of coordinate-invariant omnibus goodness-of-fit tests on compact Riemannian manifolds are proposed. The tests are based on Giné's Sobolev tests of uniformity. A condition for consistency is given. The tests are illustrated by an example on the rotation group SO(3). 1. Introduction. Although many tests of goodness of fit are available for distributions on the circle, comparatively little...

A simple scheme is presented to enable coding of toxicologic data by medical examiners or coroners who can design or direct the structure of their computer databases. Based on the English language, BLURBs are created, which consist of a prefix describing the specimen, a root word indicating the substance analyzed, and a suffix indicating the test results. BLURBs are easily interpretable and can...

This paper describes an industrial magnetic resonance multiple imaging (MRMI) system that measures nuclear magnetic resonance of several kinds of nuclei simultaneously. We use a new principle of X-ray CT. Then we reconstruct distribution images of nuclear magnetic resonance (NMR) without using usual gradient coils. We propose the construction of hardware with un-uniformity magnetic field, and a...

In this study a new passive, large particle impactor (PLPI) (PM<10) was developed and evaluated in a wind tunnel. The PLPI is designed to be isoaxial and isokinetic to enable large particles sampling without bias. The PLPI can provide representative sampling without requiring a mass flowmeter controller or pump. The PLPI is especially useful for aerosol wind tunnel studies to evaluate particle ...

We postulate a future for optical networks where data is more susceptible to errors than has been the case to date. This paper builds upon a previous study that highlighted content-dependent error in Gigabit Ethernet. In this paper we explain our previous non-uniformity results in terms of interactions between the coding scheme and observed physical layer characteristics. We also present a tool...

In this paper we propose and examine gap statistics for assessing uniform distribution hypotheses. We provide examples relevant to data integrity testing for which max-gap statistics provide greater sensitivity than chi-square (χ), thus allowing the new test to be used in place of or as a complement to χ testing for purposes of distinguishing a larger class of deviations from uniformity. We est...

Determining and understanding contributions to a shared code base can be helpful for monitoring developer efficiency, allocating work items and understanding how and why changes were made. To support this task, we introduce a method for deriving contribution using test execution results and code coverage reports. Our visualization tool, Teamline, then presents these metrics in two different vie...
