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 ...
Are PCBS in phytoplankton and zooplankton at equilibrium with the water in which they live?
(Massachusetts Institute of Technology, 2019)
Food chain bioaccumulation of polychlorinated biphenyls (PCBs) can result in harmful concentrations within higher trophic level organisms such as fish and humans. It is important to consider how the concentrations of PCBs ...
Understanding the effects of functional responses in ecological dynamical systems
(Massachusetts Institute of Technology, 2019)
The main purpose of incorporating functional responses into ecological models has been to add more realism and to help us to mechanistically explain the dynamics of species abundances in nature. Yet, their effects have not ...
Standardized structural design for post-disaster modular housing units under clustered environmental loads
(Massachusetts Institute of Technology, 2019)
This thesis addresses current shortcomings in the post-disaster housing response from a structural engineering perspective, proposing a new methodology to approach a multi-design standardized solution. Known environmental ...
