A DC power flow extension

Maher Kayal, Theodoros Kyriakidis

In this work an extension of the well-known DC power flow method is presented. A normal DC power flow of the system is executed to determine voltage angles and a novel derivation of voltage amplitudes is devised. The latter is rigorously formulated and eig ...

A DC Power Flow Extension

Ieee2013

, ,

Even though it oversimplifies reality, the dam-break problem for frictionless fluids provides predictions relevant to various manmade and natural dam-break floods. The exact solution can also be used to test numerical schemes. However, as far as we are awa ...

A printed transition is proposed to overcome problems limiting the performances of SIW horn antennas when built in thin substrates (thickness <λ 0/10). An analytical model to analyze its behavior is given along with design guidelines. The development of ...

2012

A recent method based on a specific power-law relationship between the matric potential head and the Boltzmann variable was presented by Prevedello et. al. (2008). Here, this relationship was generalized to a range of powers, and the solution extended to i ...

Extended Navigability of Small World Networks: Exact Results and New Insights

Paolo De Los Rios, Cécile Caretta Cartozo

Navigability of networks, that is, the ability to find any given destination vertex starting from any other vertex, is crucial to their usefulness. In 2000 Kleinberg showed that optimal navigability could be achieved in small world networks provided that a ...

An axisymmetric stress analysis in a single fibre composite of finite length under a thermal expansion mismatch

John Botsis, Laurent Humbert, Fabiano Colpo

In this paper, an exact solution is derived for the characterization of thermal stresses in a single-fibre composite of finite length. All the required boundary and interfacial conditions of the thermo-elastic problem are thus satisfied exactly. The propos ...

Generalized from of Telegrapher’s Equations for the Electromagnetic Field Coupling to Buried Wires of Finite Length

In this paper, a generalized form of telegrapher's equations for electromagnetic field coupling to buried wires is derived. The presented approach is based on thin-wire antenna theory. The effect of a dissipative half-space is taken into account via the re ...

Exact and Efficient Signal Reconstruction in Frequency-Domain Optical-Coherence Tomography

Michaël Unser, Rainer Leitgeb, Chandra Sekhar Seelamantula

We address the problem of tomogram reconstruction in frequency-domain optical-coherence tomography. We propose a new technique for suppressing the autocorrelation artifacts that are commonly encountered with the conventional Fourier-transform-based approac ...

Graft of the boundary integral method onto the image-source method for vehicle acoustics

Thomas Guignard, Vincent Martin

The solution obtained with the acoustical image sources method was shown to be the contribution of terms issued from a series development of the integral method (believed to be the exact solution). Missing terms in the geometrical method represent, among o ...
