Jamming transition and emergence of fracturing in wet granular media
(Massachusetts Institute of Technology, 2020)
The interplay between multiphase flow in a granular medium and the displacement of the grain particles generates a wide range of patterns, including fractures, desiccation cracks, and labyrinth structures. There are several ...
Tracking engagement : a machine learning framework for estimating affective engagement
(Massachusetts Institute of Technology, 2020)
Globally, construction fatality counts remain among the highest of all industries. As part of efforts to improve workers occupational health and safety, most companies provide workers with ongoing safety training. Yet ...
Resilience of rapid transit networks in the context of climate change
(Massachusetts Institute of Technology, 2020)
Climate change and projected rises in sea level will pose increasing flood risks to coastal cities and infrastructure. This thesis proposes a general framework of engineering resilience for infrastructure systems in the ...
Reducing inventory through supply chain coordination and improved lead times
(Massachusetts Institute of Technology, 2020)
In supply chain management, it is commonly held that reducing lead times and minimum order quantities (MOQs) from suppliers can drive down the customer's inventory levels substantially. Customers providing a consumption ...
A data-driven approach to continuous improvement in reverse logistics
(Massachusetts Institute of Technology, 2020)
Verizon may rely on third-party logistics providers (3PLs) to manage some aspects of the reverse supply chain of Fios equipment. As a result, it depends on the 3PL to continually strive for increased quality, reliability, ...
Standardization of new product introductions to achieve zero defect lines
(Massachusetts Institute of Technology, 2020)
Consistently high quality is important to any manufacturing environment, and especially so when operating in the highly regulated medical space, which typically targets zero defects in products serving patients. The New ...
A computational study of flexible routing strategies for the VRP with stochastic demands
(Massachusetts Institute of Technology, 2021)
We develop and numerically test a new strategy for the vehicle routing problem with stochastic customer demands. In our proposed approach, drivers are assigned to predetermined delivery routes in which adjacent routes share ...
Is embedding the reactor building below grade a cost-effective proposition?
(Massachusetts Institute of Technology, 2020)
The construction cost of reactor buildings has escalated substantially over time primarily for three reasons. First, new safety requirements, such as the post-9/11 airplane crash measures, have been imposed. Second, labor ...
Effect of nano Cellulose and nano carbon black on cement paste microstructure
(Massachusetts Institute of Technology, 2020)
Over the last few years, nanotechnology has emerged as a breakthrough in concrete technology exploring new frontiers for engineering multi functional properties towards higher eco-efficiency. Researchers incorporated both ...
Improving South Boston rail corridor
(Massachusetts Institute of Technology, 2020)
Rail services in older cities such as Boston include an urban metro system with a mixture of light rail/trolley and heavy rail lines, and a network of commuter services emanating from termini in the city center. These ...
