Flexure based mounts for sensitive payloads : a management and engineering study
(Massachusetts Institute of Technology, 2001)
With the cooperation of the Los Alamos National Laboratory and the Massachusetts Institute of Technology, an investigative and design study was performed to examine the history of the W80- 0 Area Aft Mount, understand its ...
Strain based preload measurement in drive axle pinion bearings
(Massachusetts Institute of Technology, 2005)
Bearing setting has a significant impact on bearing life and system performance. A strain based load measurement technique that has been previously developed and patented will be used to measure preload in automotive drive ...
Magnetic levitation for down-hole submersible pumps
(Massachusetts Institute of Technology, 2002)
The feasibility of a magnetic levitation pump for oil well down-hole use is investigated. The design, development, and testing of a closed-loop magnetic levitation pump is presented. This includes the design of the maglev ...
Effects of mechanical coupling on oscillator frequency in a micromechanical accelerometer
(Massachusetts Institute of Technology, 2001)
This thesis presents an analysis of the effect of mechanical coupling on the frequency behavior of the two oscillators in the SOA-3 micromechanical accelerometer. It also investigates the possible effect of the input ...
Modulation of African lightning and rainfall by the global five day wave
(Massachusetts Institute of Technology, 2001)
Using a field station in Rhode Island, we record electromagnetic transients caused by global mesoscale lightning activity in the Schumann resonance band (3Hz-50Hz). For this thesis, mesoscale lightning flashes originating ...
Viscoelastic polymer analysis : experimental, data analysis, and modeling techniques applied to cellular silicone foam
(Massachusetts Institute of Technology, 2002)
Design of a piezoelectric impact mechanism for tap centering
(Massachusetts Institute of Technology, 2003)
Thermal model of an annular fuel cell
(Massachusetts Institute of Technology, 2003)
The feasibility of using viscometers and flowmeters in an oilwell environment
(Massachusetts Institute of Technology, 2001)
Injection compression modeling of non-linear positive temperature coefficient circuit protection devices
(Massachusetts Institute of Technology, 2005)
Polymeric self-resettable circuit protection devices have been manufactured for many years with an extrusion based process. These devices add negligible resistance to a circuit at normal power operating conditions but ...
