Airline fleet assignment and schedule design : integrated models and algorithms
(Massachusetts Institute of Technology, 2002)
In scheduled passenger air transportation, airline profitability is critically influenced by the airline's ability to construct flight schedules containing flights at desirable times in profitable markets. In this dissertation, ...
Team interaction space effectiveness for globally dispersed teams : theory and case studies
(Massachusetts Institute of Technology, 2001)
Groups of geographically and/or organizationally dispersed members are increasingly being assembled to accomplish a wide range of organizational tasks using a combination of telecommunication and information technologies. ...
Gravity, capillary and dilational wave mode resonance at a visco-elastic two-fluid interface
(Massachusetts Institute of Technology, 2005)
(cont.) space corresponding to experimental conditions to thereby interpret the experimental results. We tested this method on noisy simulated data sets and then applied it to published experimental data sets. We designed ...
Earth pressure balance (EPB) shield tunneling in Bangkok : ground response and prediction of surface settlements using artificial neural networks
(Massachusetts Institute of Technology, 2002)
Although Earth Pressure Balance (EPB) shields have been used for several decades, very little information exists about the actual mechanisms of shield-ground interaction. The ground response mechanism induced by EPB tunneling ...
Turbulent fluid jet excavation in cohesive soil : with particular application to jet grouting
(Massachusetts Institute of Technology, 2005)
This thesis reviews the jet grouting methodology, and the current state of practice and research. Current methods of prediction of jet grout diameters are highly empirical and site specific, and do not take into account ...
A numerical framework for the direct simulation of solid-fluid systems
(Massachusetts Institute of Technology, 2001)
Our understanding of solid-fluid dynamics has been severely limited by the nonexistence of a high-fidelity modeling capability for these multiphase systems. Continuum modeling approaches overlook the microscale solid-fluid ...
A constitutive model for the compression behavior of Old Alluvium
(Massachusetts Institute of Technology, 2008)
Old Alluvium is classified as a transported, in-situ weathered tropical soil, and represents a class of geomaterials that have a complex microstructure, including cemented aggregates at the meso-scale and groups of clay ...
Topography effects in the 1999 Athens earthquake : engineering issues in seismology
(Massachusetts Institute of Technology, 2004)
It is well known that irregular topography can substantially affect the amplitude and frequency characteristics of seismic motion. Macroseismic observations of destructive earthquakes often show higher damage intensity at ...
Ductility enhancement of high performance cementitious composites and structures
(Massachusetts Institute of Technology, 2002)
High performance cementitious composites (HP2C) are a new generation of fiber reinforced cementitious composites (FRCC) with substantial improvements in mechanical behavior. The most important development in these HP2C ...
Moisture degradation in FRP bonded concrete systems : an interface fracture approach
(Massachusetts Institute of Technology, 2005)
(cont.) characterization, and kink criterion implementation, form a synergistic analysis of the mechanistic debonding behavior affected by moisture. Results have shown that moisture affected debonding is a highly complex ...
