Voltage Collapse and ODE Approach to Power Flows: Analysis of a Feeder Line with Static Disorder in Consumption/Production
Voltage Collapse Consumption/Production Feeder Line Static Disorder
2011/9/15
We consider a model of a distribution feeder connecting multiple loads to the sub-station. Voltage is controlled directly at the head of the line (sub-station), however,voltage anywhere further down t...
Clustering with Prototype Extraction for Census Data Analysis
Prototype Extraction Clustering Census Data Analysis
2011/9/15
Not long ago primary census data became available to publicity. It opened qualitatively new perspectives not only for researchers in demography and sociology, but also for those people, who somehow fa...
Analysis and Optimisation of Pulse Dynamics for Magnetic Stimulation
Magnetic stimulation, TMS, inductive stimulation, waveform optimization,neuron model, loss power.
2011/9/2
Magnetic stimulation is a standard tool in brain research and many elds of neurology, as well as psychiatry. From a physical perspective, one key aspect of this method is the ineciency of available ...
A Large-Scale Community Structure Analysis In Facebook
Community Structure Analysis Facebook
2011/9/13
In this work we present a large-scale community structure detection and analysis applied to the largest Online Social Network actually existing, namely Facebook. This network gathers more than 500 mil...
Harmonic analysis of spherical sampling in diffusion MRI
Harmonic analysis spherical sampling diffusion MRI
2011/9/9
In the last decade diffusion MRI has become a powerful tool to non-invasively study white-matter integrity in the brain. Recently many research groups have focused their attention on multi-shell spher...
Novel analysis of the decays psi' -> h_c pi^0 and eta_c'-> chi_{c0} pi^0
decays psi' charmonium decays
2010/3/16
We show that in the transitions \psi^\prime \to h_c \pi^0 and \eta_c'\to \chi_{c0} \pi^0 the contributions from charmed meson loops are highly suppressed, in contrast to various other charmonium decay...
A causality analysis of the linearized relativistic Navier-Stokes equations
transport equations Navier-Stokes equations
2010/3/18
It is shown by means of a simple analysis that the linearized system of transport equations for a relativistic, single component ideal gas at rest obeys the \textit{antecedence principle}, which is of...
Phenomenological analysis of elastic scattering reactions using different models
Heavy-ion scattering Regge pole analysis Strong absorption models

Phenomenological analysis of elastic scattering reactions using different models.
Analysis of instabilities and pattern formation in time fractional reaction-diffusion systems
instabilities pattern formation time fractional reaction-diffusion systems
2010/4/6
We analyzed conditions for Hopf and Turing instabilities to occur in two-component fractional reaction-diffusion systems. We showed that the eigenvalue spectrum and fractional derivative order mainly ...
A 3-D four-wing attractor and its analysis
Chaos four-wing attractor Lyapunov exponents bifurcation
2010/7/8
In this paper, several three dimensional (3-D) four-wing smooth quadratic autonomous chaotic systems are analyzed. It is shown that these systems have a number of similar features. A new 3-D continuou...
Theoretical Analysis of Formation and Sustainment Methods for Compact Toroids
Theoretical Analysis Formation and Sustainment Methods Compact Toroids
2010/10/27
Recent theoretical studies on the use of neutral beams (NB), rotating magnetic fields (RMF) and helicity injection (HI) to form and sustain compact toroids are reported. A Monte Carlo code was employe...
Two-Parameter Analysis of the Temporal Behaviour of Resistive Detectors
Two-Parameter Analysis the Temporal Behaviour of Resistive Detectors
2010/10/26
The biggest constraint in the RPCs operation is the drop of their efficiency with the counting rate, consequence of charge gain decrease. This effect is normally attributed to the voltage drop on the ...
Analysis of Concrete Material through Gamma Ray Computerized Tomography
Concrete Material Gamma Ray Computerized Tomography
2010/10/26
Computerized Tomography (CT) refers to the cross sectional imaging of an object from both transmission or reflection data collected by illuminating the object from many different directions. The most ...
Analysis on the 2-Dim Quantum Poincare Group at Roots of Unity
2-Dim Quantum Poincare Group homogeneous spaces
2010/4/15
2--Dim quantum Poincar\'e Group Eq(1,1) at roots of unity, its dual Uq(e(1,1)) and some of its homogeneous spaces are introduced. Invariant integrals on Eq(1,1) and its invariant discrete subgroup E(1...
