Range sensing for 3D object reconstruction and visualization
(Massachusetts Institute of Technology, 2003)
Toward improved transit station access in pedestrian-unfriendly environments
(Massachusetts Institute of Technology, 2001)
The resurgence of rail transit in the United States has introduced transit stations into environments of dispersed development oriented primarily to automobile travel. In addition, alignments for new transit lines have ...
Outsourcing transportation infrastructure maintenance : a theoretical approach with application to JR East
(Massachusetts Institute of Technology, 2004)
In transportation agencies, how to reduce maintenance and operation cost is one of the biggest and most common concerns, because their revenue is not expected to increase drastically in the future. One of the solutions ...
The significance of specimen end restraint in high pressure triaxial testing of cohesive soil
(Massachusetts Institute of Technology, 2011)
This thesis investigates the mechanical behaviour of cohesive soil at relatively high stresses with a particular emphasis on the significance of specimen end restraint on the interpretation of triaxial test results. Undrained ...
The elastic properties of calcium leached cement pastes and mortars : a multi-scale investigation
(Massachusetts Institute of Technology, 2002)
Calcium leaching induced aging in concrete creates a new material with degraded macroscopic mechanical properties. Although the degradation of strength has been elaborately studied in the last decade, the degradation of ...
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 ...
Development of software architecture for environmental monitoring using wireless sensor networks
(Massachusetts Institute of Technology, 2006)
In this thesis, I describe the development of the software architecture for temperature monitoring using Wireless Sensor Networks (WSN). The goal of the software is to provide a means to remotely monitor and analyze ...
Numerical simulation of the response of sandy soils treated with pre-fabricated vertical drains
(Massachusetts Institute of Technology, 2009)
This research is part of the ongoing effort of the Seismic Risk Mitigation for Port Systems Grand Challenge. It addresses the problem of numerically simulating the response of sandy soils treated with earthquake drains, ...
Improving on-time delivery performance through the implementation of lean supply chain management
(Massachusetts Institute of Technology, 2002)
Computer-supported virtual collaborative learning and assessment framework for distributed learning environment
(Massachusetts Institute of Technology, 2002)
