ABSTRACTSolar ultraviolet erythemal irradiance (UVER) has been studied on inclined planes with different orientations in Valencia, Spain. To do this a platform was designed that could turn through 90° on its own axis. The radiometers were inclined at an angle close to the latitude of Valencia (39.5° N).

Spatial coherence profilometry on tilted surfaces
Applied Optics, 2009The influence of tilted surfaces on the measurement of shape by spatial coherence profilometry is investigated. Based on theoretical analysis and experimental results, the systematic measurement error caused by surface tilt is determined. The systematic measurement error depends not only on the tilt angle but also on the parameters of the experimental ...

Optimizing the parameters of tilting surfaces in robotic workcells
2015 IEEE International Conference on Automation Science and Engineering (CASE), 2015Pick-and-place regrasp is an important grasp and manipulation skill for a robot to rearrange the world around it. This paper discusses how to design a tilted work surface for robotic workcells so that the robot inside the cell can improve its pick-and-place regrasps.

Surface tilt perception with a biomimetic tactile sensor
2016 6th IEEE International Conference on Biomedical Robotics and Biomechatronics (BioRob), 2016Humans are known to be good at manipulating tools. To cope with disturbances and uncertainties from the external environment during such tasks, they must be able to perceive small changes in orientation or tilt of the tool using mechanoreceptors in the glabrous skin of the fingertips. We hypothesize that the most sensitive part of human fingers, a flat

Proceedings of the 14th international conference on Human-computer interaction with mobile devices and services companion, 2012
This demonstration accompanies a full paper accepted into MobileHCI '12 [1]. We demonstrate a new type of actuatable display, called a Tilt Display, that provides visual feedback combined with multi-axis tilting and vertical actuation. Its ability to physically mutate provides users with an additional information channel that facilitates a range of new

The Effect of Surface Tilt on Nanoindentation Results
Volume 10: Mechanics of Solids and Structures, Parts A and B, 2007The effect of surface tilt on results of nanoindentation tests is studied for Berkovich, cube corner and conical indenters. The true projected areas are calculated as a function of tilt angle and orientation using the exact three dimensional geometry of each indenter. The true area is compared with the area when there is no tilt and the resulting error

Tilt of the Electron Fermi Surface in Bi
Physical Review, 1968Many experiments show that the long axes of the three extremely prolate ellipsoids which represent the electron Fermi surface in bismuth are tilted \ensuremath{\sim}6\ifmmode^\circ\else\textdegree\fi{} from the trigonal plane of the Brillouin zone; however, the sign of this tilt angle cannot be unambiguously obtained from the literature.

Tilt angle effects in surface grinding with mounted points
Production Engineering, 2014Modern 5-axis machining centers enable the development and use of new machining kinematics and grinding strategies to grind workpieces with superabrasives mounted points. One of these technologies is the oscillating surface grinding (OSG), which can improve the surface characteristics and the tribological properties of machined surfaces. In the current

Low-energy electron diffraction (LEED) is a widely employed technique for the structural characterization of crystalline surfaces and epitaxial adsorbates. For technical reasons the accessible reciprocal space is limited at a given primary electron energy E.
