A simplified software architecture for self-updating Building Information Models (BIM)
(Massachusetts Institute of Technology, 2009)
Building Information Modeling (BIM) is an emerging software technology that is revolutionizing the architecture, engineering, and construction (A/E/C) industry. BIM technology employs "object-based 3D models-containing the ...
Application of a gradient-based algorithm to structural optimization
(Massachusetts Institute of Technology, 2009)
Optimization methods have shown to be efficient at improving structural design, but their use is limited in the engineering practice by the difficulty of adapting state-of-the-art algorithms to particular engineering ...
Numerical simulation of the response of sandy soils treated with pre-fabricated vertical drains
(Massachusetts Institute of Technology, 2009)
This research is part of the ongoing effort of the Seismic Risk Mitigation for Port Systems Grand Challenge. It addresses the problem of numerically simulating the response of sandy soils treated with earthquake drains, ...
Preferential mode of gas invasion in sediments : grain-scale model of coupled multiphase fluid flow and sediment mechanics
(Massachusetts Institute of Technology, 2009)
We present a discrete element model for simulating, at the grain scale, gas migration in brine-saturated deformable media. We rigorously account for the presence of two fluids in the pore space by incorporating forces on ...
Introducing the starlet sea anemone Nematostella vectensis as a model for investigating microbial mediation of health and disease in hexacorals
(Massachusetts Institute of Technology, 2009)
All animals in their natural state harbor complex communities of microbes including those that are beneficial (symbionts), neutral, or harmful (pathogens). The dynamic interactions between animals and their microbiota often ...
Ground source heat storage and thermo-physical response of soft clay
(Massachusetts Institute of Technology, 2009)
Ground source heat storage can condition buildings with reduced consumption of fossil fuels, an important issue in modem building design. However, seasonal heat storage can cause soil temperature fluctuations and possibly ...
Evaluating airline delays : the role of airline networks, schedules, and passenger demands
(Massachusetts Institute of Technology, 2009)
In this thesis, we develop a framework for analyzing airlines' operational performances under different strategic decisions. A detailed study is conducted to compare differences between a major U.S. legacy carrier and a ...
Development and test of dynamic congestion pricing model
(Massachusetts Institute of Technology, 2009)
Dynamic congestion pricing is an approach to control the traffic flow on the network by setting variable tolls that are adjusted with time based on the traffic condition. Different models have been developed and tested in ...
Use of advanced composite materials for innovative building design solutions/
(Massachusetts Institute of Technology, 2009)
Advanced composite materials become popular in construction industry for the innovative building design solutions including strengthening and retrofitting of existing structures. The interface between different materials ...
Anomalous Eurasian snow extent and the wintertime AO
(Massachusetts Institute of Technology, 2009)
The winter mode of the Arctic Oscillation (AO) is the dominating influence on extratropical winter climate variability in the Northern Hemisphere (NH) . The phase of the Arctic Oscillation is characterized by trends in ...
