Solar cooking : the development of a thermal battery
(Massachusetts Institute of Technology, 2007)
There are many rural area in the world where cooking fuel is very scarce. One solution to this problem is to use solar energy to cook food. However most people around the world like to cook large meals at night, when the ...
Design of an STM and EPL control system and linear actuator preload diaphragm
(Massachusetts Institute of Technology, 2007)
Increasing demand for nano-scale machining processes in the semiconductor industry necessitates new mechanisms for nano-machining. A system capable of nano-scale machining of conductive material via Electronic Pen Lithography ...
Design and process/measurement for immersed element control in a reconfigurable vertically falling soap film
(Massachusetts Institute of Technology, 2007)
Reinforcement learning has proven successful at harnessing the passive dynamics of underactuated systems to achieve least energy solutions. However, coupled fluid-structural models are too computationally intensive for ...
The behavior of rotator cuff tendon cells in three-dimensional culture
(Massachusetts Institute of Technology, 2007)
The rotator cuff is composed of the supraspinatus, infraspinatus, subcapularis, and teres minor tendons. Rotator cuff injuries are common athletic and occupational injuries that surgery cannot fully repair. Therefore tendon ...
Valuing project financing using Monte Carlo simulation, with application to the expansion of a chemical company
(Massachusetts Institute of Technology, 2005)
The purpose of this thesis is to analyze the specific project value of a chemical company that undertook a major expansion in the late 1990s. The actual details of the investment were unique and conditional on the level ...
Redesign of the double hand rim modification of the "Whirlwind" Wheelchair for manufacture in developing nations
(Massachusetts Institute of Technology, 2004)
In this thesis, I investigate possible improvements to the design of a wheelchair for manufacture in a developing nation, specifically one designed for use by persons with hemiplegia. Ralf Hotchkiss's "Whirlwind" Wheelchair ...
Experimental simulation of wind driven cross-ventilation in a naturally ventilated building
(Massachusetts Institute of Technology, 2004)
A device was designed and constructed to simulate cross-ventilation through a building due to natural wind. The wind driver device was designed for use with a one tenth scale model of an open floor plan office building in ...
A low-cost defocus blur module for video rate quantified 3D imaging
(Massachusetts Institute of Technology, 2004)
Existing three-dimensional surface imaging systems are expensive, difficult to use, time consuming, and do not always provide the best accuracy or resolution. By using an offset aperture on a rotating disc, the 3D Monocular ...
Implementation of finite element analysis into the athletic shoe design process
(Massachusetts Institute of Technology, 2004)
Finite element analysis is used by companies throughout the world as a substitution for manually testing prototypes. With the assistance of finite element analysis many companies and industries have decreased the time and ...
Design and characterization of a gel loading mechanism for an ultra-high throughput mutational spectrometer
(Massachusetts Institute of Technology, 2005)
A process known as Constant Denaturant Capillary Electrophoresis is used to separate mutant from wild-type DNA at fractions down to 10-7. A device known as an Ultra-high Throughput Mutational Spectrometer is being created ...
