High density polyethylene (HDPE) containers as an alternative to polyethylene terephthalate (PET) bottles for solar disinfection of drinking water in northern region, Ghana
(Massachusetts Institute of Technology, 2007)
The purpose of this study is to investigate the technical feasibility of high density polyethylene (HDPE) containers as an alternative to polyethylene terephthalate (PET) bottles for the solar disinfection of drinking water ...
Matching of lowest fare seat availability in airline revenue management systems
(Massachusetts Institute of Technology, 2007)
By enabling passengers to compare easily and book directly from airline inventories, Internetbased ticket distribution has forced airlines to compete for the lowest price level and more importantly, to ensure seat availability ...
Low cost monitoring system to diagnose problematic rail bed : case study of Mud Pumping Site
(Massachusetts Institute of Technology, 2007)
This thesis describes the development of low cost sensors and wireless sensor network (WSN) platform aimed at characterizing problematic rail beds (subgrade). The instrumentations are installed at a busy high-speed Northeast ...
Comparison of three widely-used aerodynamic modifications that minimize the impact of wind loads on tall buildings
(Massachusetts Institute of Technology, 2007)
For tall buildings, motion caused by wind is usually the most damaging to the lateral support system. As a result, engineers have invented many different methods to limit the motion of the buildings, for example dampers, ...
Fair adjustment strategies for airline revenue management and reservation systems
(Massachusetts Institute of Technology, 2007)
With the growth of Low Cost Carriers (LCC) and their use of simplified fare structures, the airline industry has seen an increased removal of many fare restrictions, especially in markets with intense LCC presence. This ...
Nanomechanical properties of hydrated organic thin films
(Massachusetts Institute of Technology, 2007)
Hydrated organic thin films are biological or synthetic molecularly thin coatings which impart a particular functionality to an underlying substrate and which have discrete water molecules associated with them. Such films ...
Seismic design of a current woodframe structure and study of innovative products and damping systems in wood construction
(Massachusetts Institute of Technology, 2007)
Wood structures have seen resurgence in popularity over the past several decades, especially in Western States of America, such as California. The industry keeps creating new structural wood products of exceptional strength, ...
Conceptual design of a building with movable parts
(Massachusetts Institute of Technology, 2007)
Although we live in a Dynamic Universe filled with movement, the design methodology that has been given to Architecture is clearly static: buildings look the same all the time. As an approach to "Dynamic Architecture", the ...
Effects of water on chemomechanical instabilities in amorphous silica : nanoscale experiments and molecular simulation
(Massachusetts Institute of Technology, 2007)
We elucidate the tensile failure mechanism of amorphous silica and the effects of water on the process, combining: (a) atomic force microscope (AFM) bending tests, (b) molecular dynamics (MD) simulation and (c) molecular ...
