R&D and deployment valuation of intelligent transportation systems : a case example of the intersection collision avoidance systems
(Massachusetts Institute of Technology, 2006)Compared with investments in the conventional infrastructure, those in Intelligent Transportation Technology (ITS) include various uncertainties. Because deployment of ITS requires close public-private partnership, projects ... -
Radium cycling in groundwater : implications for bioremediation and tracer studies
(Massachusetts Institute of Technology, 2019)Radium (Ra) is a radioactive alkaline earth element and forms naturally from the decay of uranium (U) and thorium (Th), elements that are ubiquitous within most rocks, soils and sediments. Radium contamination associated ... -
Rail service design and database management for new automobile distribution
(Massachusetts Institute of Technology, 1994) -
Rail transit OD matrix estimation and journey time reliability metrics using automated fare data
(Massachusetts Institute of Technology, 2007)The availability of automatic fare collection (AFC) data greatly enhances a transit planner's ability to understand and characterize passenger travel demands which have traditionally been estimated by manual surveys handed ... -
Rail transit operations analysis : framework and applications
(Massachusetts Institute of Technology, 2001) -
Railroad marketing support system based on the freight choice model
(Massachusetts Institute of Technology, 1995) -
Rainfall-induced Landslide Hazard Rating System
(Massachusetts Institute of Technology, 2011)This research develops a Landslide Hazard Rating System for the rainfall-induced landslides in the Chenyulan River basin area in central Taiwan. This system is designed to provide a simplified and quick evaluation of the ... -
Rainfall-runoff as spatial stochastic processes : data collection and synthesis.
(Massachusetts Institute of Technology, 1975) -
Range sensing for 3D object reconstruction and visualization
(Massachusetts Institute of Technology, 2003) -
Rapid development of a wireless infrastructure monitoring system
(Massachusetts Institute of Technology, 2004)Much academic literature exists in the fields of Product Development and Project Management. This thesis uses the framework provided by the literature to analyze a case study development project which the author led from ... -
Rapid redox transformations of arsenic and characterization of the internal seiches in the Upper Mystic Lake, Medford, Massachusetts
(Massachusetts Institute of Technology, 1995) -
Rapid remote determination of hydrographic data for modified surf Index calculations and naval applications
(Massachusetts Institute of Technology, 2020)Amphibious operations present a unique set of challenges to naval personnel. Among these challenges is the need to rapidly obtain reliable real-time data for the surf zone, a high-energy environment in which beach profiles ... -
"Rapid" innovation and integration of components : comparison of user and manufacturer innovations through a study of residential construction
(Massachusetts Institute of Technology, 1991) -
A rating system to test private investment decisions in public infrastructure projects
(Massachusetts Institute of Technology, 1998)This thesis will develop a basic method to evaluate the overall quality of proposed infrastructure projects for private sector financial investment. INFRATEST is meant to aid both potential private infrastructure developers ... -
Rational interpretation of in-situ tests in cohesive soils
(Massachusetts Institute of Technology, 1992) -
Rational manipulation of substrate-supported graphene by heterogeneity of substrate surface and material composition
(Massachusetts Institute of Technology, 2017)In many graphene-based devices graphene is adhered to a substrate that influences its performance, rather than being present in a free standing form. The interaction of graphene with these substrates can lead to deformations ... -
Re-analysis of deep excavation collapse using a generalized effective stress soil model
(Massachusetts Institute of Technology, 2010)This thesis re-analyzes the well-documented failure of a 30m deep braced excavation underconsolidated marine clay. Prior analyses of the collapse of the Nicoll Highway have relied on simplified soil models with undrained ... -
