Understanding human mobility patterns through mobile phone records : a cross-cultural study
(Massachusetts Institute of Technology, 2011)
In this thesis, I present a cross-cultural study on human's trip length distribution and how it might be influenced by regional socio-economic factors, such as population density, income and unemployment rate. Mobile phone ...
Seismic response of wharf structures supported in liquefiable soil
(Massachusetts Institute of Technology, 2013)
This research analyzes the vulnerability of wharf structures supported on loose granular waterfront fills that are susceptible to liquefaction during seismic events and considers the effectiveness of pre-fabricated Vertical ...
Critical enhancements of a dynamic traffic assignment model for highly congested, complex urban network
(Massachusetts Institute of Technology, 2010)
To accurately replicate the highly congested traffic situation of a complex urban network, significant challenges are posed to current simulation-based dynamic traffic assignment (DTA) models. This thesis discusses these ...
Bursting bubbles and water-to-air-transfer : interplay between underlying physics and microbial contamination
(Massachusetts Institute of Technology, 2019)
Surface bubbles are very efficient at transporting microorganisms and chemicals from water bodies to the atmosphere: upon burst, they release a multitude of droplets known to shape climate and to participate to airborne ...
Laboratory study of the atmospheric heterogeneous oxidation of benzo[a]pyrene
(Massachusetts Institute of Technology, 2019)
Polycyclic aromatic hydrocarbons (PAHs) are a class of chemical pollutants found ubiquitously in the environment. PAHs are carcinogenic and mutagenic, and the reaction of PAHs in the atmosphere can significantly alter their ...
Characterization, prediction, and mitigation of Code Help events at Massachusetts General Hospital
(Massachusetts Institute of Technology, 2019)
This thesis suggests a method to characterize congestion alarms triggered by the Emergency Department (ED) at Massachusetts General Hospital, attempts to predict the incidence of these alarms using logistic regression, and ...
Designing internal logistics processes for new manufacturing site
(Massachusetts Institute of Technology, 2019)
The Boeing Company is the world's largest aerospace company and is constantly evaluating improvement opportunities to the production system. It is of ongoing interest to the company to have to tools to assess new manufacturing ...
Evaluating the impact of critical product quality attributes on patient outcomes in biologics
(Massachusetts Institute of Technology, 2019)
The primary goal of this project is to link critical product quality attributes in biological medicines with patient outcomes as evidenced by clinical trial data. This project adopts a novel methodology of applying statistical ...
Predicting solder defects in printed circuit board assembly (PCBA) process
(Massachusetts Institute of Technology, 2019)
Printed circuit boards (PCBs) are core components of virtually every modern electronic device, from smartphones to servers. Accordingly, printed circuit board assembly (PCBA) has become core to Flex, a leading electronics ...
Improving order prioritization for the allocation of constrained supply
(Massachusetts Institute of Technology, 2019)
For top wholesale retail companies, the demand for products from US-based customers (wholesale, digital, and direct to consumer) is extremely high. However, the available supply of a product is contingent upon the success ...
