Rotary compressor model for investigating compressor performance and reliability
(Massachusetts Institute of Technology, 1998) -
Rotary fast tool servo component design
(Massachusetts Institute of Technology, 1999)This thesis covers the design and implementation of the components of a novel rotary fast tool servo (RFTS). The RFTS enables diamond turning of rotationally asymmetric optics, with an emphasis on eyeglass lenses. These ... -
A rotary fast tool servo for diamond turning of asymmetric optics
(Massachusetts Institute of Technology, 1999)This thesis presents analysis, design, and control techniques developed for machines that diamond-turn asymmetric surfaces. Examples of this type of surface include spectacle and contact lenses, human lens implants, elements ... -
A rotary shape memory alloy actuator for CubeSat deployable structures
(Massachusetts Institute of Technology, 2017)Over a decade of continuing CubeSat technology improvements are driving the wide adoption of CubeSats for research and commercial missions. Resource constraints onboard CubeSats still limit their ability to support multi-use ... -
Rotary-linear axes for high speed machining
(Massachusetts Institute of Technology, 2001)This thesis presents the design, analysis, fabrication, and control of a rotary-linear axis; this axis is a key subsystem for high speed, 5-axis machine tools intended for fabricating centimeter-scale parts. The rotary-linear ... -
Rotating convection driven by differential bottom heating and its application
(Massachusetts Institute of Technology, 1996) -
A rotating disk study of impurity segregation in aluminum alloy solidification
(Massachusetts Institute of Technology, 2019)The presence of impurities during the solidification of aluminum alloys can be detrimental to alloy properties and performance. As aluminum manufacturers aim to increase the amount of recycled scrap in direct-chill cast ... -
Rotation analysis of a microfabricated fatigue test structure
(Massachusetts Institute of Technology, 1999) -
Rotation and torsional stress sensing via coherent optics
(Massachusetts Institute of Technology, 1995) -
Rotation generation and transport in tokamak plasmas
(Massachusetts Institute of Technology, 2012)Plasma toroidal rotation is a factor important for plasma stability and transport, but it is still a fairly poorly understood area of physics. This thesis focuses on three aspects of rotation: momentum transport, Ohmic ... -
Rotation invariant real-time face detection and recognition system
(Massachusetts Institute of Technology, 2001) -
Rotation of a slender rod injected into a cylindrical constraint
(Massachusetts Institute of Technology, 2016)We investigate the buckling of a slender elastic rod injected into a cylindrical constraint while undergoing axial rotation. Particular focus is given to extension of the helical buckling length. This problem is of particular ... -
The rotation of the moon
(Massachusetts Institute of Technology, 1980) -
Rotation studies in fusion plasmas via imaging X-ray crystal spectroscopy
(Massachusetts Institute of Technology, 2008)The increase in plasma performance associated with turbulence suppression via flow shear in magnetically confined fusion plasmas has been well documented. Currently, the standard methods for both generating and measuring ... -
Rotational and vibrational energy transfer in methane
(Massachusetts Institute of Technology, 1988) -
Rotational effects on turbine blade cooling
(Massachusetts Institute of Technology, 1994) -
Rotational lightcurve analysis of binary Asteroid (22) Kalliope/Linus
(Massachusetts Institute of Technology, 2008)Binary asteroids have been insightful to scientists in recent years in their quest to better understand the Solar System in its early stage. Observing a mutual event between a primary and its moon can yield the sizes of ... -
Rotational movement of a harbor seal whisker during vortex induced vibrations
(Massachusetts Institute of Technology, 2015)Harbor seal whiskers have geometry that reduces vortex induced vibrations. Previous experiments with rigid models of the harbor seal whiskers has shown that the reduced vibration of the whisker can be used to detect the ... -
Rotational speed dependent motor properties
(Massachusetts Institute of Technology, 2018)The coils of alternating current (AC) motors experience back electromotive force (EMF) at high rotational speeds, which acts against applied voltage and drops motor efficiency steeply. By reducing the magnetic flux surrounding ... -
Rotational Transformation Methods for Radio Occultation and Passive Microwave Radiometry Colocation Analysis
(Massachusetts Institute of Technology, 2021-06)Global Navigation Satellite System Radio Occultation (GNSS-RO) and passive microwave radiometry (MWR) provide useful atmospheric profiles for inputs into Numerical Weather Prediction models. However, both remote sensing ...
