In photorealistic rendering, one often wants to work with functions defined over a hemisphere (one-half of a sphere), centered around a surface point. A hemisphere consists of all the directions in ...
The robot uses a single motor to drive its hemispherical omnidirectional gimbaled wheel, propelling it across the floor at amazing speeds with uncanny agility. The robot uses a simple two axis ...
A focused x-ray spot on the sample increases the sensitivity on small samples. The HR-XPS in our lab is equipped with a twin anode (Al K α at 1486.6 or Ag L α at 2984.3 eV) FOCUS 500 monochromator and ...
These methods enable three-dimensional orientation data to be displayed in two dimensions and manipulated graphically. One way to form a two-dimensional plot associated with vectors on the lower ...
