The day activity schedule approach to travel demand analysis
(Massachusetts Institute of Technology, 1998)
This study develops a model of a person's day activity schedule that can be used to forecast urban travel demand. It is motivated by the notion that travel outcomes are part of an activity scheduling decision, and uses ...
Effect of polysulfides on cinnabar solubility, partitioning, and methylation by Desulfovibrio desufuricans
(Massachusetts Institute of Technology, 1999)
Sulfate reducing bacteria are believed to be the most important methylators of mercury in aquatic systems. Methylation may be controlled by the availability of mercury to these bacteria and therefore may depend on mercury ...
Analyis [sic] and design of drilled shafts in rock
(Massachusetts Institute of Technology, 1999)
Drilled shafts are widely used to transfer heavy structural loads (both axial and lateral) through the overburden soil to the underlying rock mass. It is important to consider the effect of discontinuities when designing ...
The chemistry of chlorine in combustion systems and the gas-phase formation of chlorinated and oxygenated pollutants
(Massachusetts Institute of Technology, 1999)
A major concern during the combustion of chlorinated fuels is the formation of chlorinated organic pollutants, which are potentially dangerous to human health and to the environment. Observed combustion byproducts include ...
Natural abundance of ¹⁵N as a tool for assessing patterns of nitrogen loss from forest ecosystems
(Massachusetts Institute of Technology, 1999)
Stable isotopes provide an integrated measure of the nitrogen cycling history of a site. Among ecosystems with contrasting nitrate loss patterns, the [delta]15 N of soil and plant material should be higher at sites with ...
Size distributions, population dynamics, and single-cell properties of marine plankton in diverse nutrient environments
(Massachusetts Institute of Technology, 1999)
The goal of this thesis is to study the relationship between the community structure of marine microorganisms and nutrient availability. To this end, size spectra of microbes were studied over a range of nutrient regimes, ...
A simulation laboratory for evaluation of dynamic traffic management system
(Massachusetts Institute of Technology, 1997)
Laboratory measurements of three-dimensional breaking waves
(Massachusetts Institute of Technology, 1999)
