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...

center pivot irrigation system is used as a modern irrigation method in different parts of iran. unfortunately due to lack of proper design and hydraulic shortcomings of the system in several agricultural lands in iran, the efficiency of the center pivot irrigation system is low or unacceptable. low system efficiency results in non-uniformity of water distribution along the lateral and on the c...

Circular data are measured in angles or directions, which occur a wide variety of scientific fields. An often investigated hypothesis is that circular uniformity, isotropy. Frequentist methods for assessing the uniformity null exist, but do not allow user faced with an insignificant result to distinguish lack power from support hypothesis. Bayesian tests, solve this issue and several others, de...
