Momentum and scalar transport in vegetated shear flows
(Massachusetts Institute of Technology, 2005)
Environmental aquatic flows are seldom free of vegetative influence. However, the impact of submerged vegetation on the hydrodynamics and mixing processes in aquatic flows remains poorly understood. In this thesis, I present ...
Generation of sand bars under surface waves
(Massachusetts Institute of Technology, 2005)
(cont.) Experiments were performed in a large wave flume to validate the theory and to study additional aspects of sand bar evolution. The wave envelope and bar profile were recorded for low and high beach reflection, ...
Household adoption of ecological sanitation : an assessment of agricultural value and user perspectives in Nyanza Province, Kenya
(Massachusetts Institute of Technology, 2005)
Ecological sanitation, or ecosan, refers to a range of sanitation technologies in which human excreta is recovered and retained on-site, and eventually reused. However, when a culture does not have a tradition of reusing ...
Innovation in the AEC industry through wireless sensor networks
(Massachusetts Institute of Technology, 2005)
I came to the Massachusetts Institute of Technology (MIT) to learn about technological innovation and entrepreneurship. More precisely, I wanted to know more about how to leverage Information Technology (IT) in the ...
A transit route simulator for the evaluation of control strategies using automatically collected data
(Massachusetts Institute of Technology, 2005)
This thesis develops and tests an extensible simulation model that uses automatically collected transit data to simulate transit route operations, demand, and control mechanisms. This model is motivated by the increasing ...
Appropriate water treatment for the Nyanza Province of Kenya
(Massachusetts Institute of Technology, 2005)
In 2000 the Centers for Disease Control and Prevention (CDC) in conjunction with CARE International began working with several local non-governmental organizations (NGOs) in the Nyanza Province of Kenya to reduce the rate ...
Structural feasibility of a medium-rise timber office building
(Massachusetts Institute of Technology, 2005)
Using timber as a structural material for commercial projects will certainly gain importance and popularity in the coming decades as more focus is placed on reducing environmental effects created by a dependence on steel ...
Discrete particle transport in porous media : discrete observations of physical mechanisms influencing particle behavior
(Massachusetts Institute of Technology, 2005)
An understanding of how discrete particles in the micron to submicron range behave in porous media is important to a number of environmental problems. Discrete particle behavior in the interior of a porous medium is complex ...
Regional earthquake loss estimation : role of transportation network, sensitivity and uncertainty, and risk mitigation
(Massachusetts Institute of Technology, 2005)
Large earthquakes near densely populated areas such as the 1994 Northridge and 1995 Kobe events have caused extensive damage to the physical infrastructure and losses to the regional and national economies. Economic losses ...
Material invariant properties of shales : nanoindentation and microporoelastic analysis
(Massachusetts Institute of Technology, 2005)
Shales compose the major part of sedimentary rocks and cover most of hydrocarbon bearing reservoirs. Shale materials are probably one of the most complex natural composites, and their mechanical properties are still an ...
