Relationships in design build
(Massachusetts Institute of Technology, 2010)
As design build (DB) becomes more popular, different ways of writing contracts and forming relationships with the various parties are being considered. The main point of this paper is to look at the relationships between ...
A nanomechanical investigation of the crack tip process zone of marble
(Massachusetts Institute of Technology, 2010)
This study explores the interaction between crack initiation and nanomechanical properties in the crack tip process zone (zone of microcracking at the tip of a propagating crack) of a brittle geomaterial. Samples of Carrara ...
Using automatically collected data to improve the bus service planning process
(Massachusetts Institute of Technology, 2010)
Most large transit agencies have shifted from collecting transit performance data manually to using automated data systems to measure performance. These systems, which include Automatic Vehicle Location (AVL), Automatic ...
Using GPS data in route choice analysis : case study in Boston
(Massachusetts Institute of Technology, 2010)
The pervasive location-based technologies, such as GPS and cell phone, help us find the pattern of geographical information of human behavior and also help dig opportunities in real world. In transportation field, they ...
A study of the dynamics of shotcrete formwork
(Massachusetts Institute of Technology, 2010)
This study models and analyzes the dynamic behavior of shotcrete formwork during standard application procedure. Based on standard shotcrete application, a program was developed to simulate shotcrete application and the ...
Adaptation to water scarcity in glacier-dependent towns of the Indian Himalayas : impacts, adaptive responses, barriers, and solutions
(Massachusetts Institute of Technology, 2010)
Among the existing and projected impacts of climate change, impacts on water resources are expected to exacerbate the current and future threat of global water scarcity. Glacier-dependent societies are especially vulnerable ...
The effect of compositional and geometrical changes to the bending strength of the Ghanaian ceramic pot filter
(Massachusetts Institute of Technology, 2010)
Pure Home Water (PHW) is a non-profit organization with the goal of providing safe drinking water through household water treatment and storage (HWTS) to the inhabitants of Ghana, particularly in the Northern Region. To ...
Integrated transportation and energy activity-based model
(Massachusetts Institute of Technology, 2010)
There is a long history of projects and regulations that have had limited or even counterproductive results. These unforeseen effects are due to the failure of planners to capture all of the complexity inherent in urban ...
Development Impacts of high-speed rail : megalopolis formation and implications for Portugal's Lisbon-Porto High-Speed Rail Link
(Massachusetts Institute of Technology, 2010)
High-speed rail (HSR) has been gaining acceptance worldwide with development of rail technology and rising concerns over climate change and congestion in airports and on roads. The implementation of high-speed rail lines ...
Evaluating passenger delays in the US domestic air transportation system
(Massachusetts Institute of Technology, 2010)
A fundamental component of any National Airspace System (NAS) performance evaluation is the cost impact of air traffic delays, and more generally capacity limitations, on the traveling passengers. In previous research it ...
