Sobol’ sequence generators are used actively in financial applications. In this paper, we explore the effect of the uniformity Properties A and A’ on the generator performance in high-dimensional problems. It is shown that these properties provide an additional guarantee of uniformity for highdimensional problems even at a small number of sampled points. By imposing additional uniformity proper...

The present objectives of the Drive Uniformity Program at the University of Rochester are (a) to determine the radiation and drive uniformity requirementsfordirectly driven targets, and(b)toachieve the required degree of uniformity with multiple beam irradiation of spherical targets using overlapping beams. This integrated program, which began almost two years ago, has made steady progress in m...

This paper discusses the fundamental hypothesis of policy uniformity under centralized decision making underlying Oates’ famous decentralization theorem. The theorem has come under pressure by the prediction that local public goods are provided to minimum winning coalitions rather than uniformly. The focus of this paper is on the impact of uniformity rules on political accountability. Using the...

We investigate the problem of detecting a point set’s deviation from uniformity in the unit hypercube. High uniformity is for example desirable in Monte Carlo methods for numerical integration, but also for obtaining a good worst-case bound in global optimization. In high dimensions, many points are required to get reliable results, so the point sets are preferably generated by fast methods suc...

Irrigation has become commonplace for residential homeowners desiring high quality landscapes in Florida. The goal of this project was to document irrigation system uniformity in Central Florida and to quantify distribution uniformity of residential sprinkler equipment under controlled conditions. The catch-can testing procedure used was a modified version of both the American Society of Agricu...

This paper concerns some notes about the inequality index based on the ratios between lower and upper arithmetic means recently proposed by Zenga [2006]. Beside some definitions and notation given in section 2, we show (section 3) that the inequality measure proposed fulfills the population replication principle. In the remainder of the paper our purpose is to consider a population partitioned ...

In pointfree topology, the notion of uniformity in the form of a system of covers was introduced by J. Isbell in [11], and later developed by A. Pultr in [14] and [15]. Another equivalent notion of locale uniformity was given by P. Fletcher and W. Hunsaker in [6], which they called “entourage uniformity”. The purpose of this paper is to formulate and investigate an alternative definition of ent...

Infrared focal plane arrays (IRFPA) sensors, due to their high sensitivity, high frame frequency and simple structure, have become the most prominently used detectors in military applications. However, they suffer from a common problem called the fixed pattern noise (FPN), which severely degrades image quality and limits the infrared imaging applications. Therefore, it is necessary to perform n...

The reactions were performed to synthesize carbon materials using wheat straw powder as raw material. The wheat straw powder was first hydrolyzed at the absence of a catalyst at 190 °C for 1 h, then the hydrolyzate solution was used as carbon source to prepare carbon materials via hydrothermal carbonization at 180 °C in the absence of a catalyst for 8 h. The influence of solid-liquid-ratio of w...
