Topological complexity of motion planning in projective product spaces
Topological complexity product projective spaces Euclidean immersions of manifolds generalized axial maps
<
2012/6/14
We study Farber's topological complexity (TC) of Davis' projective product spaces (PPS's). We show that, in many non-trivial instances, the TC of PPS's coming from at least two sphere factors is (much...
First Passage Times for a Tracer Particle in Single File Diffusion and Fractional Brownian Motion
First Passage Times Tracer Particle Single File Diffusion Fractional Brownian Motion Biological Physics
<
2012/5/29
We investigate the full functional form of the first passage time density (FPTD) of a tracer particle in a single-file diffusion (SFD) system whose population is: (i) homogeneous, i.e., all particles ...
Hydrostatic Level Sensors as High Precision Ground Motion Instrumentation for Tevatron and Other Energy Frontier Accelerators
Accelerator applications Accelerator modeling and simulations Instrumentation for particle accelerators and storage rings
<

We have studied long period, 206 and 412 day, variations in tidal sea level corresponding to various moon phases collected from five observatories in the Northern and Southern hemispheres. Variations ...
A spatio-temporal Gaussian-Conical wavelet with high aperture selectivity for motion and speed analysis
Extraction of motion parameters speed tuning continuous wavelet transform directional and conical wavelets
<
2012/5/25
The construction of a spatio-temporal wavelet and its tuning to speed was first realized in the 90s on the Morlet wavelet by M. Duval-Destin \cite{Duval-Destin91a,Duval-Destin92}. This enabled to demo...

Motion by Volume Mean Curvature Flow Cylinders Analysis of PDEs
<
2012/5/24
Center manifold analysis can be used in order to investigate the stability of the stationary solutions of various PDEs. This can be done by considering the PDE as an ODE between certain Banach spaces ...
Active Brownian motion of an asymmetric rigid particle

2012/5/17
Individual movements of a rod-like self-propelled particle on a flat substrate are quantified. Biological systems that fit into this description may be the Gram-negative delta-proteobacterium Myxococc...
Does Lorentz Force Law Contradict the Principle and Theories of Relativity for Uniform Linear Motion?
Lorentz Force Law Principle and Theories of Relativity Uniform Linear Motion Classical Physics
<
2012/5/29
I show that no force or torque is generated in cases involving a charge and a magnet with their relative velocity zero, in any inertial frame of reference. A recent suspicion of an anomalous torque an...
Doubting, Testing, and Confirming Galileo: A translation of Giovanni Battista Riccioli's experiments regarding the motion of a falling body, as reported in his 1651 Almagestum Novum
Doubting Testing Confirming Galileo translation of Giovanni Battista Riccioli's experiments motion of a falling body History and Philosophy of Physics
<

2012/4/23
This paper is devoted to the construction of a solution for the "Inhomogenous skew Brownian motion" equation, which first appeared in a seminal paper by Sophie Weinryb, and recently, studied by \'{E}t...
Is the aether entrained by the motion of celestial bodies? What do the experiments tell us?
aether the motion of celestial bodies experiments General Physics
<
2012/4/20
Even though the concept has evolved and if the designation as aether is improperly regarded as outdated, nobody today considers that the vacuum is empty. However, the nature and the properties of the ...
Ambient beam motion and its excitation by ghost lines in the Tevatron

<
2012/2/28
Transverse betatron motion of the Tevatron proton beam is measured and analyzed. It is shown that the motion is coherent and excited by external sources of unknown origins. Observations of the time-va...
