This paper presents a simple three phase power flow method for solution of three-phase unbalanced radial distribution system (RDN) with voltage dependent loads. It solves a simple algebraic recursive expression of voltage magnitude, and all the data are stored in vector form. The algorithm uses basic principles of circuit theory and can be easily understood. Mutual coupling between the phases h...

This paper presents a simple three phase load flow method to solve three-phase unbalanced radial distribution system (RDS). It solves a simple algebraic recursive expression of voltage magnitude, and all the data are stored in vector form. The algorithm uses basic principles of circuit theory and can be easily understood. Mutual coupling between the phases has been included in the mathematical ...

Abstract—This paper explain the primary balancing of single cylinder engine and optimizing the counter balancing mass to reduce the unbalanced forces coming on the crankshaft. After optimizing, the effect of primary balancing is validated. After primary balancing, the vibration is measured on the engine at various locations. Balancer shaft is designed for the unbalanced forces exist after prima...

Modeling land-use change is a prerequisite to understanding the complexity of land-usechange patterns. This paper presents a novel method to model urban land-use change using support-vector machines (SVMs), a new generation of machine learning algorithms used in classification and regression domains. An SVM modeling framework has been developed to analyze land-use change in relation to various ...

Recently, since single phase loads and dispersed generators become widespread, unbalanced voltage in distribution line become an important problem for voltage management. One of them is that the control of a conventional voltage regulation device become difficult because of the difference of the magnitude of the line voltages, the other one is increase of 3rd harmonic voltages. The authors prop...

The yield was measured after the harvest. Because the 3 rd method was not tested on the 4 th type of field (because of a lack of seeds), and the 2 nd method on the 4 th type of field (because of a hail storm), the experiment is a typical example of an unbalanced ANOVA. We have performed an ANOVA with interactions in order to determine the interactions between the types of methods used and the t...

In this paper, the author puts forward a variation of Feige’s Hypothesis, which claims that it is hard on average refuting Unbalanced Max 3-XOR against biased assignments on a natural distribution. Under this hypothesis, the author strengthens the previous known hardness for approximating Minimum Unique Game, 5/4 − ǫ, by proving that Min 2-Lin-2 is hard to within 3/2 − ǫ and strengthens the pre...

Abstract: This is a trial-use standard for definitions used for measurement of electric power quantities under sinusoidal, nonsinusoidal, balanced, or unbalanced conditions. It lists the mathematical expressions that were used in the past, as well as new expressions, and explains the features of the new definitions.

Previous work on the production and comprehension of focus-to-prosody mapping make different claims on the existence of a production-precedingcomprehension asymmetry in acquisition, whereby children pass through a stage of producing the right prosodic pattern but not using the focus-to-prosody mapping to the fullest extent in their comprehension, before reaching adult-like behaviour in both. Th...
