Biped robot walking control on inclined planes with fuzzy parameter adaptation [PDF]

open access: yes, 2010
The bipedal structure is suitable for a robot functioning in the human environment, and assuming assistive roles. However, the bipedal walk is a poses a difficult control problem.

Adaptive finite element simulation of three-dimensional surface tension dominated free-surface flow problems [PDF]

open access: yes, 2005
An arbitrary Lagrangian--Eulerian finite element method is described for the solution of time-dependent, three-dimensional, free-surface flow problems.

Velocity correlations in dense granular flows

open access: yes, 2004
Velocity fluctuations of grains flowing down a rough inclined plane are experimentally studied. The grains at the free surface exhibit fluctuating motions, which are correlated over few grains diameters.

Mapping Earth Analogs from Photometric Variability: Spin-Orbit Tomography for Planets in Inclined Orbits

open access: yes, 2012
Aiming at obtaining detailed information of surface environment of Earth analogs, Kawahara & Fujii (2011) proposed an inversion technique of annual scattered light curves named the spin-orbit tomography (SOT), which enables one to sketch a two ...

Shocks in sand flowing in a silo [PDF]

open access: yes, 2001
We study the formation of shocks on the surface of a granular material draining through an orifice at the bottom of a quasi-two dimensional silo. At high flow rates, the surface is observed to deviate strongly from a smooth linear inclined profile giving

Investigation of a 1-D Fluid Probe Model for Mach Probe Measurements [PDF]

open access: yes, 2004
In this paper we show how a two dimensional fluid model can be used to interpret data obtained from an inclined Mach-probe or a Gundestrup probe. We use an analytical approximation of the solution of the differential equations describing the relation ...

A thin rivulet of perfectly wetting fluid subject to a longitudinal surface shear stress [PDF]

open access: yes, 2008
The lubrication approximation is used to obtain a complete description of the steady unidirectional flow of a thin rivulet of perfectly wetting fluid on an inclined substrate subject to a prescribed uniform longitudinal surface shear stress.

Solar Radiation on Inclined Surfaces [PDF]

open access: yesNature, 1964
CALCULATION of the probable intensity of solar radiation on a surface which is inclined to the horizontal and at any attitude or azimuth relative to the Sun's meridian is frequently necessary in solar engineering research. The usual practice has been to perform such a calculation by separating the direct component of insolation and the diffuse ...

On a slender dry patch in a liquid film draining under gravity down an inclined plane [PDF]

open access: yes, 2001
In this paper two similarity solutions describing a steady, slender, symmetric dry patch in an infinitely wide liquid film draining under gravity down an inclined plane are obtained.
