However, because the samples selected did not account for the large mechanical variation that may occur in orientation of collagen fibres within different parts of the animal hide and randomly sampled from parchment artefacts the variance in the data was too large to support strong conclusions.
In the 3 August Physical Review Letters, researchers report that they have devised a sensitive new scheme for mapping these variations that relies on the quantum mechanical nature of atoms.
It was his variations that helped him.
Within those two basic categories of snow throwers, also known as snow blowers, however, are scores of mechanical variations, engines, snow-clearing capabilities and combinations of features that result in price tags that range from under $100 to $2,400 or even more.
You can just crack on with it, if that's your flavour; or, you can tinker with a myriad of mechanical variations within each set of wheels, personalising the experience to suit your own racing style.
The trick, in Mr. Tilden's view, is to equip simple-minded but physically robust robots with mechanical variations on animal nervous systems.
This study analyzed variations in mechanical properties that depend on the injection molding process during the blending of short glass fiber (SGF) and polytetrafluoroethylene (PTFE) reinforced polycarbonate (PC) composites.
Our goal was to understand whether or not this shape variation could produce variation in mechanical energy expenditure that was of similar magnitude to the variation among individuals in metabolic cost of transport that has been previously documented empirically.
To determine whether or not shape matters at the intraspecific level, we used a mechanical model that had properties that mimic human variation in shape.
The articular cartilage and subchondral bone plate exhibit considerable topographical variations in thickness, density, biochemical composition and vascularity as a consequence of the different mechanical loads that exist within the same joint.
