Fracture and hydraulic fracture initiation, propagation and coalescence in shale
(Massachusetts Institute of Technology, 2017)
Even though hydraulic fracturing has been in use for more than six decades to extract oil and natural gas, the fundamental mechanism to initiate and propagate these fractures remains unclear. Moreover, it is unknown how ...
Market characteristics of future oil tanker operations
(Massachusetts Institute of Technology, 2014)
This work analyzes the market characteristics of future oil tanker operations with a particular emphasis on those aspects which will have a potential impact on the design of future vessels. The market analysis model used ...
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 ...
A nanomechanical investigation of the crack tip process zone of marble
(Massachusetts Institute of Technology, 2010)
This study explores the interaction between crack initiation and nanomechanical properties in the crack tip process zone (zone of microcracking at the tip of a propagating crack) of a brittle geomaterial. Samples of Carrara ...
Simulation of hydrology and population dynamics of Anopheles mosquitoes around the Koka Reservoir in Ethiopia
(Massachusetts Institute of Technology, 2014)
This thesis applies the HYDRology, Entomology and MAlaria Transmission Simulator (HYDREMATS) to the environment around a water resources reservoir in Ethiopia. HYDREMATS was modified to simulate the local hydrology and the ...
The mechanical behavior of heavily overconsolidated resedimented Boston Blue Clay
(Massachusetts Institute of Technology, 2013)
Geotechnical engineers encounter some of the most challenging problems in heavily overconsolidated soils. Clays under this condition originated in nature or man-made construction. This thesis investigates the mechanical ...
Reagent usage optimization In high volume diagnostics testing
(Massachusetts Institute of Technology, 2018)
Company X provides healthcare diagnostics testing services. The company competes in the market by providing cost effective, short turn-around-time (TAT) solutions and a large variety of test selections. Reducing operating ...
Automated structural damage detection using one class machine learning
(Massachusetts Institute of Technology, 2014)
Measuring and analysing the vibration of structures using sensors can help identify and detect damage, potentially prolonging the life of structures and preventing disasters. Wireless sensor systems promise to make this ...
The study of shear and longitudinal velocity measurements of sands and cohesive soils
(Massachusetts Institute of Technology, 2012)
This thesis evaluates some methods for the measurement of stiffness parameters of soils, with an emphasis on the use of bender element technology in obtaining the shear modulus. The experimental program consisted two primary ...
Piecewise truckload network procurement
(Massachusetts Institute of Technology, 2011)
Faced with procuring transportation over its freight network, a shipper can either bid out all of its lanes at once, or somehow divide up the network and bid it out in pieces. For large shippers, practical concerns such ...
