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 ...
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 ...
The nanogranular origin of concrete creep : a nanoindentation investigation of microstructure and fundamental properties of calcium-silicate-hydrates
(Massachusetts Institute of Technology, 2008)
With an annual per capita consumption of one cubic meter, concrete is the most manufactured material on Earth. But concrete subject to sustained load creeps, like chewing gum, at a rate that deteriorates the durability and ...
Optimizing flow rate and bacterial removal performance of ceramic pot filters in Tamale, Ghana
(Massachusetts Institute of Technology, 2015)
Pure Home Water (PHW) is an organization that seeks to improve the drinking water quality for those who do not have access to clean water in Northern Ghana. This study focuses on the further optimization of ceramic pot ...
Understanding bus passenger crowding through origin destination inference
(Massachusetts Institute of Technology, 2016)
Comfort is an important aspect of the transit passenger experience. Crowding can significantly decrease passenger comfort and disrupt service delivery, causing passenger travel times to increase and even resulting in ...
Urban physics : molecular approach to city texture analysis for controlling Urban Heat Island
(Massachusetts Institute of Technology, 2016)
Defined as intensification of urban air temperatures when compared to their rural surroundings common to cause negative externalities ranging from imperiling human health and comfort to amplifying energy costs and air ...
Understanding the evolution of transportation pricing and commuting at MIT : a study of historical commuting data
(Massachusetts Institute of Technology, 2016)
In summer of 2016, the Massachusetts Institute of Technology will introduce Access MIT, a new commuter benefits program aimed at reducing employee single occupancy vehicle (SOV) commuting. This initiative is the latest in ...
Overdue invoice forecasting and data mining
(Massachusetts Institute of Technology, 2016)
The account receivable is one of the main challenges in the business operation. With poor management of invoice to cash collection process, the over due invoice may pile up, and the increasing amount of unpaid invoice may ...
The use of a distributed hydrologic model to predict dynamic landslide susceptibility for a humid basin in Puerto Rico
(Massachusetts Institute of Technology, 2009)
This thesis describes the use of a distributed hydrology model in conjunction with a Factor of Safety (FS) algorithm to predict dynamic landslide susceptibility for a humid basin in Puerto Rico. The Mameyes basin, located ...
A simplified software architecture for self-updating Building Information Models (BIM)
(Massachusetts Institute of Technology, 2009)
Building Information Modeling (BIM) is an emerging software technology that is revolutionizing the architecture, engineering, and construction (A/E/C) industry. BIM technology employs "object-based 3D models-containing the ...
