To improve the water application uniformity for sprinkler irrigation on sloping land, indoor tests were conducted on an artificial slope (slopes of 0, 0.05, 0.10 and 0.15) to evaluate the effects of two riser orientations, vertical (VO) and ...

Technical Evaluation of Classic Stationary Sprinkler Irrigation Systems with Travelling Sprinklers in Eghlid, Fars Province [PDF]
Due to the climatic conditions of Iran, the limitations of irrigation resources, and low irrigation efficiency in traditional methods, on the one hand, and the existence of arenas for the development of blue land and the increasing need for food, on the ...

Tax uniformity as a requirement of justice [PDF]
Barbara Fried takes the view that uniform taxation-that is, a single rate applicable to all income levels-cannot be defended on any grounds of justice. She goes further by saying that, of all possible rate structures, it might be "the hardest one"?

Testing multivariate uniformity and its applications [PDF]
Some new statistics are proposed to test the uniformity of random samples in the multidimensional unit cube[0,1]d (d≥2).[0,1]^d\ (d\ge 2).These statistics are derived from number-theoretic or quasi-Monte Carlo methods for measuring the discrepancy of points in[0,1]d[0,1]^d.

Uniformity seminorms on $\ell^\infty$ and applications [PDF]
A key tool in recent advances in understanding arithmetic progressions and other patterns in subsets of the integers is certain norms or seminorms. One example is the norms on $\Z/N\Z$ introduced by Gowers in his proof of Szemer di's Theorem, used to detect uniformity of subsets of the integers. Another example is the seminorms on bounded functions in

EFFICIENCY AND UNIFORMITY OF AN SUBSURFACE DRIP IRRIGATION SYSTEM IN SUGARCANE CROP
Agricultural productivity in irrigated areas depends on several factors, including the design and maintenance of irrigation systems. Excessive or insufficient applications of water affect plant growth and development, hence agricultural productivity ...

Uniformization: Basics, extensions and applications
Uniformization, also referred to as randomization, is a well-known performance evaluation technique to model and analyse continuous-time Markov chains via an easier to performance measures via iteration of the one-step transition matrix of the discrete-time Markov chain.
