We report on novel three-dimensional tunable Fabry-Perot etalons fabricated by surface micromachining technique. The Fabry-Perot etalons are tuned by rotation or translation movements. For the Fabry-Perot etalon tuned by rotational movement, the Fabry-Perot etalon is integrated with a rotational stage and the effective light path distance is adjusted by rotating the stage. The transmission peak...

This paper presents the development of an innovative motion simulator, based on the Eclipse-II mechanism, which is a redundantly actuated parallel kinematic mechanism, with a partially decoupled architecture in its rotational motion. This parallel mechanism can generate six degrees of freedom motion, including continuous rotation through 360 degrees, and translation in any direction. After all ...

This paper presents a new approach for fast and accurate generation of cubic spline trajectories for non-circular omnidirectional mobile robots and automated guided vehicles (AGVs). This method can be combined with any existing path planner or guidance system for offline calculation of trajectories with independent translational and rotational movement. In addition trough fast computation this ...

Langmuir monolayers as disordered solids: Strain-state calculations applied to stearic acid" (1997). This paper presents a calculational procedure to determine the equilibrium phase for a given surface pressure ␲. The monolayer is treated as orientationally free tails grafted to a two-dimensional net formed by the head groups of the amphiphilic molecules. The head groups form a subsystem with t...

the ground state rotational bands of some rare earth nuclei show a rather strange behaviour at large values of angular momenta. the nuclear moment of inertia teta increases smoothly with angular momentum i up to i=12. then at about i=14 there is a sudden increase in the moment of inertia. the plot of teta versus the square of the angular velocity w gives a s-shaped curve. we attempt here to rep...

in this research, the compositing of the surface of az31b magnesium alloy with cnt was studied by fsp. the parameters under study were rotational speed (500-1500 rpm), transverse speed (12-44 mm/min), number of passes (1-4), and cnt weight fraction (0-2%). microhardness testing, optical metallography, fesem, and eds analysis were employed for the characterization of the samples. the suitable li...

introduction: many factors are related to the disability of subjects with chronic low back pain. fear-avoidance of injury and movement are the most important risk factors to increase the disability followed by decreased physical activity in these patients. the aim of current study was to compare the level of disability and fear-avoidance between two groups of low back pain patients with and wit...

magnetic abrasive finishing (maf) is a micromachining process that uses magnetic field and magnetic abrasive particles to conduct the mechanism of material removal in micro-nanometer scales. in this paper, by an experimental method and statistical analysis, the effects of parameters like working gap, work-piece rotational speed and material removal mechanism (injection of abrasive slurry of al2...
