Evaluation of the KanchanTM Arsenic Filter under various water quality conditions of the Nawalparasi District, Nepal
(Massachusetts Institute of Technology, 2011)
In 2002, the Massachusetts Institute of Technology Department of Civil and Environmental Engineering partnered with the Environment and Public Health Organization to develop and disseminate the KanchanTM Arsenic Filter ...
Limit analysis of the Great Hall of Trajan's Markets in Rome using equilibrium methods
(Massachusetts Institute of Technology, 2011)
This paper studies the Great Hall of Trajan's Markets in Rome using equilibrium analysis to determine the limits of stability of its main vault under gravity loading. In particular, the capacities of three structural ...
Friction-based control system for seismic energy dissipation with isolated stories
(Massachusetts Institute of Technology, 2011)
The implementation of various structural control systems, such as passive, semi-active or active is not a new concept. They are incorporated in structures to increase the performance under seismic and/or wind loading either ...
Improving the estimation of platform wait time at the London Underground
(Massachusetts Institute of Technology, 2011)
In recent years, the proliferation of automatically collected data has allowed many transit agencies to complete more frequent and thorough analyses of service quality. However, while the types and quality of automatically ...
Assessing the impact of recent fare policy changes on public transport demand in London
(Massachusetts Institute of Technology, 2011)
Public transit agencies across the world have been moving towards electronic ticketing technology and to take advantage of the greater flexibility, have made changes in fare structure. Over the last decade, Transport for ...
Tilt-up concrete panels : an investigation of flexural stresses and punching shear during lifting
(Massachusetts Institute of Technology, 2011)
Tilt-up construction is becoming more popular in the United States due to its ease of construction, reliability, and relatively low construction and maintenance costs. In its most typical form, a concrete panel is cast on ...
The development of a life cycle cost model for railroad tunnels
(Massachusetts Institute of Technology, 2011)
Today, Life Cycle Costing is one of the most popular ways of assessing a project's or an investment's worth to a company. This method of assessment is often applied to all stages of a investment's lifecycle, starting from ...
Structural dynamics of community gene expression In a freshwater cyanobacterial bloom over a day-night cycle
(Massachusetts Institute of Technology, 2011)
Studies of community gene expression, or metatranscriptomics, provide a powerful approach for quantifying changes in both the taxonomic composition (structure) and activity (function) of complex microbial systems in response ...
Laboratory evaluation of the constant rate of strain and constant head techniques for measurement of the hydraulic conductivity of fine grained soils
(Massachusetts Institute of Technology, 2011)
This thesis evaluates the constant rate of strain and constant head techniques for measurement of the hydraulic conductivity of fine grained soils. A laboratory program compares hydraulic conductivity measurements made ...
Statistical nano-chemo-mechanical assessment of shale by wave dispersive spectroscopy and nanoindentation
(Massachusetts Institute of Technology, 2011)
Shale is a common type of sedimentary rock formed by clay particles and silt inclusions, and, in some cases, organic matter. Typically, shale formations serve as geological caps for hydrocarbon reservoirs. More recently, ...
