An analysis of the fundamental constraints on low cost passive radio-frequency identification system design
(Massachusetts Institute of Technology, 2001)
Passive radio frequency identification (RFID) systems provide an automatic means to inexpensively, accurately, and flexibly capture information. In combination with the Internet, which allows immediate accessibility and ...
Manufacturing initiatives in a decentralised company
(Massachusetts Institute of Technology, 2001)
Response surface methods applied to submarine concept exploration
(Massachusetts Institute of Technology, 2001)
It is estimated that 70 to 85 percent of a naval ship's life-cycle cost is determined during the concept exploration phase which places an importance in the methodology used by the designer to select the concept design. ...
Simulation of real-time scheduling policies in multi-product, make-to-order semiconductor fabrication facilities
(Massachusetts Institute of Technology, 2001)
Vibration-induced rotation
(Massachusetts Institute of Technology, 2001)
This thesis presents, explores, and documents the validation of a mechanical mechanism dubbed Vibration-Induced Rotation, or VIR. The tendency of threaded fasteners to move under the influence of vibrations is well known, ...
Design, fabrication, experimentation and analysis of high-speed microscale gas bearings
(Massachusetts Institute of Technology, 2001)
Microengine Program. The all-silicon device consist of a free-rotating microturbine, with 4.2 mm rotor diameter, enclosed within a five wafer fusion-bonded stack. Of note are the low aspect ratio journal bearing and large ...
Mechanics, mechanisms, and modeling of the chemical mechanical polishing process
(Massachusetts Institute of Technology, 2001)
The ever-increasing demand for high-performance microelectronic devices has motivated the semiconductor industry to design and manufacture Ultra-Large-Scale Integrated (ULSI) circuits with smaller feature size, higher ...
A novel capillary polymerase chain reaction machine
(Massachusetts Institute of Technology, 2001)
I built a novel prototype capillary polymerase chain reaction machine. The purpose was to perform a single reaction as fast as possible with a reaction volume - 100 nl. The PCR mix is in the form of a 1 /1 droplet that ...
On the development of a universal automated fixturing system through encapsulation techniques
(Massachusetts Institute of Technology, 2001)
Universal automated fixturing can transform a machine tool into a rapid prototyping machine with many advantages over current rapid prototyping methods. Using this modified machine tool, prototype parts can be manufactured ...
Development and analysis of nondestructive electrokinetic cartilage diagnostics
(Massachusetts Institute of Technology, 2001)
