  • The Halphen Family of Distributions for Modeling Maximum
    Transactions on Ecology and the Environment vol 6, © 1994 WIT Press, www.witpress.com, ISSN 1743-3541 The Halphen family of distributions for modeling maximum annual flood series: New developments L. Perreault, V. Fortin & B. Bobee Chair on Statistical Hydrology, 2800 rue Einstein, Sainte-Foy, Quebec, Canada, G1V 4C7 Abstract Design of hydraulic structures, optimal operation of reservoirs, and flood forecasting involve estimation of flood flows x^,, with given specified return period T. This estimation is generally achieved by fitting a probability distribution to observed data. In this paper, we briefly present some recent theoretical results of a study on Halphen distributions which were developed in the early forties but have been little used due to the computational complexity. This family of three distributions was motivated by Halphen's desire to construct probability models which met specific requirements of fitting hydrological variables. Halphen probability models have great potential applicability in statistical flood analysis but are not yet familiar to hydrologists. 1 Introduction Engineering activities such as the design of hydraulic structures, the management of water resources systems, and the prevention of flood damage, all require an estimation of flood characteristics. The objective of flood frequency analysis FFA is to estimate the flood x^ exceeded in average once every T year, which may be used to design, for example, spillways or as prior information in real- time flood forcasting models. At gauged locations, x? may be estimated by fitting a parametric distribution F(x; 0) to observed maximum annual floods, where x refer to an observation and 0 to a vector of parameters.

E. Crooks – Field Guide to Probability Distributions Preface: The search for GUD A common problem is that of describing the probability distribution of a single, continuous variable. A few distributions, such as the normal and exponential, were discovered in the 1800’s or earlier. But about a century ago the great statistician, Karl Pearson, realized that the known probabil- ity distributions were not sufficient to handle all of the phenomena then under investigation, and set out to create new distributions with useful properties. During the 20th century this process continued with abandon and a vast menagerie of distinct mathematical forms were discovered and invented, investigated, analyzed, rediscovered and renamed, all for the purpose of de- scribing the probability of some interesting variable. There are hundreds of named distributions and synonyms in current usage. The apparent diver- sity is unending and disorienting. Fortunately, the situation is less confused than it might at first appear. Most common, continuous, univariate, unimodal distributions can be orga- nized into a small number of distinct families, which are all special cases of a single Grand Unified Distribution. This compendium details these hun- dred or so simple distributions, their properties and their interrelations.

In the work presented both deterministic and statistical approaches for harmonic analysis have been used. Investigations have been made both in Time and Frequency Domains. An already available computer simulation program in Time Domain has been used to derive frequency domain models of distribution feeders with composite loads. A Frequency Domain computer program has been modified to give the statistical data of harmonic voltage distortion levels of a large power system. The thesis examines some of the fundamental assumptions used in harmonic analysis with the aid of a Time Domain simulation program. In harmonic analysis two of the commonly made assumptions are: (i) harmonic sources are represented with ideal ac current sources having equal phase angles, (ii) non-distorting loads are represented with constant impedances.

Wideband harmonics from modern wind turbines (WTs) are observed to be stochastic, associated with real power production, and they may adversely interact with the grid impedance and cause unexpected harmonic resonance, if not comprehensively addressed in the planning and commissioning of the WPPs. These issues should become more critical as wind penetration levels increase. We thus propose a planning study framework comprising the following functional steps: First, the best fitted probability density functions (PDFs) of the harmonic components of interest in the frequency domain are determined. In operations planning, maximum likelihood estimations (MLEs) followed by a chi-square test are used once field measurements or manufacturers’ data are available.

  • Exact Solution for the Singlet Density Distributions and Second-Order Correlations of Normal-Mode Coordinates for Hard Rods in One Dimension C
    JOURNAL OF CHEMICAL PHYSICS VOLUME 110, NUMBER 23 15 JUNE 1999 Exact solution for the singlet density distributions and second-order correlations of normal-mode coordinates for hard rods in one dimension C. Daniel Barnes and David A. Kofke Department of Chemical Engineering, State University of New York at Buffalo, Buffalo, New York 14260-4200 ~Received 8 December 1998; accepted 25 March 1999! We examine the distribution of normal-mode coordinates ~defined via the eigenvectors of a chain of harmonic oscillators! for a system of purely repulsive hard rods in one dimension. We obtain an exact solution for the singlet density distribution, and separately for the covariances of the normal-mode coordinates. The hard-rod behavior is examined in terms of its deviation from the corresponding distributions for the system of harmonic oscillators. All off-diagonal covariances are zero in the hard-rod system, and the ~on-diagonal! variances vary with the normal-mode wave number exactly as in the harmonic system. The detailed singlet normal-mode density distributions are very smooth but nonanalytic, and they differ from the ~Gaussian! distributions of the corresponding harmonic system. However, all of the normal-mode coordinate distributions differ in roughly the same way when properly scaled by the distribution variance, and the differences vanish as 1/N in the thermodynamic limit of an infinite number of particles N.©1999 American Institute of Physics. @S0021-9606~99!51523-7# I.

Kerestes 2014 iii ESTIMATION OF HARMONICS, INTERHARMONICS AND SUB-HARMONICS IN MOTOR DRIVE SYSTEMS Robert Kerestes, Ph.D. University of Pittsburgh, 2014 Harmonic analysis in power systems is a challenge that is always evolving due to a constantly changing power grid. Advances in power electronics have led to the installation of many new non-linear power loads, such as power converters, arc furnaces and motor drive systems, which in turn change the existing infrastructure and inject new types of harmonics. This study analyzes a static Kramer drive system for its harmonic behavior. The system is broken down component- by-component and analyzed. The analysis includes classical harmonics of integer multiple of the fundamental frequency as well as sub-harmonics and interharmonics. This paper shows that there are significant harmonic issues in a static Kramer drive that are likely to be present in similar drive systems.

Starting with a perturbative approach, we show that it is possible to achieve a number of analytic results, ranging from the up-conversion probability to the statistical properties of the generated light. In particular, the moments and the correlations of the photon-number distribution of the second-harmonic light generated by any initial state are retrieved. When possible, a comparison with the results achieved with the classical regime is successfully provided. The nonclassicality of some benchmark states is investigated by inspecting the corresponding autocorrelation function. Keywords: second-harmonic generation; quantum description of interaction of light and matter; photon statistics and coherence theory 1. Introduction Following the first observation of second-harmonic generation (SHG) by Franken et al.

Sub- sequently, we show that the corrected Bessel-Gaussian distribution can fit the simulated data better than the Bessel-Gaussian distribution in the more peripheral collisions. Inspired by Gram-Charlier A series, we introduce a new set of cumulants qnf2kg that are more natural to study distributions near Bessel-Gaussian. These new cumulants are obtained from cnf2kg where the collision geometry effect is extracted from it. By exploiting q2f2kg, we introduce a new set of estimators for averaged ellipticityv ¯2 which are more accurate compared to v2f2kg for k > 1. As another application of q2f2kg, we show we are able to restrict the phase space of v2f4g, v2f6g and v2f8g by demanding the consistency ofv ¯2 and v2f2kg with q2f2kg equation. The allowed phase space is a region such that v2f4g − v2f6g & 0 and 12v2f6g − 11v2f8g − v2f4g & 0, which is compatible with the experimental observations.
