organic manure plays an important role in the improvement of soil structure by decreasing bulk density and increasing porosity. however, the method of manure spreading influences its beneficial impact on soil structure. in this study, a novel helical manure distributor machine capable of spreading manure with different moisture contents at maximum distribution width was developed and the machin...

2 I. INTRODUCTION Power system economics procedure includes of two aspects: active power regulation and reactive power dispatch. This forms a global optimization problem of a large-scale industrial system.The reactive power problem is less manageable to solve than the active power problem due to its more complicated relationship between variables. The reactive power problem is largelyassociated...

The following presents a review of power laws in financial economics. It is a chapter from a preliminary draft of a very long review article called “Beyond equilibrium and efficiency”. While some of the discussion is specific to economics, most of it applies to power laws in general – the nouns may change, but the underlying questions are similar in many fields. This draft is still highly preli...

Previous approximate qua...

This project will develop (a) design theory and method for planning hybrid (discrete, continuous) power system controllers, and (b) economic systems, applicable to power system energy markets, for recovering and allocating costs of design and installation of such controllers. Discrete-event system theory and integer programming optimization methods will be used in the control design. The econom...

We construct a theory of distributions in the setting of analysis on post-critically finite self-similar fractals, and on fractafolds and products based on such fractals. The results include basic properties of test functions and distributions, a structure theorem showing that distributions are locally-finite sums of powers of the Laplacian applied to continuous functions, and an analysis of th...

We describe an exchange market consisting of many agents with stochastic preferences for two goods. When individuals are indifferent between goods, statistical mechanics predicts that goods and wealth will have steady state gamma distributions. Simulation studies show that gamma distributions arise for a broader class of preference distributions. We demonstrate this mathematically in the limit ...

With the development of critical loads, power quality problem has become particularly important and poor power quality will be cause many adverse effects and the cost of many deaths will follow. To improve power quality and protection of sensitive loads against grid disturbances have been used new equipment based on power electronics similar FACTs devices, they are Custom Power. One of the most...
