CVT for a Small Electric Vehicle Using Centrifugal Belt Pulley

open access: yesEnergies, 2022
In a conventional continuously variable transmission (CVT), the belt slides up and down along the slope of the pulley to shift gears. Efficiency is reduced because of slippage from the shifting of the belt.

Vortex equilibria in flow past a plate [PDF]

open access: yes, 2008
Families of vortex equilibria, with constant vorticity, in steady flow past a flat plate are computed numerically. An equilibrium configuration, which can be thought of as a desingularized point vortex, involves a single symmetric vortex patch located ...

Inevitability of Plate Tectonics on Super-Earths [PDF]

open access: yes, 2007
The recent discovery of super-Earths (masses less or equal to 10 earth-masses) has initiated a discussion about conditions for habitable worlds. Among these is the mode of convection, which influences a planet's thermal evolution and surface conditions ...

Dietary cyclic fatty acids derived from linolenic acid do not exhibit intrinsic toxicity in the rat during gestation

open access: yesAnimal, 2008
Heating oils and fats may lead to cyclization of polyunsaturated fatty acids, especially those showing multiple double bonds like linolenic acid. Cyclohexenyl and cyclopentenyl fatty acids are subsequently present in some edible oils and these were ...

Mechanical and finite element models of corneal keratoprostheses

open access: yesAdvanced Engineering Research, 2020
Introduction. When developing ocular prostheses, a number of problems arise, one of which is the construction of the connection between the hard optical part and the soft corneal tissue. Their Young's modules can differ by three orders of magnitude.
