The role of organizational culture in creating secure and resilient supply chains
(Massachusetts Institute of Technology, 2005)
This thesis aims to understand the role that organizational culture plays in creating secure and resilient supply chains. The terrorist attacks of September 11, 2001, and the government's subsequent response, propelled ...
The evaluation of regional water balances using different hydrometeorological datasets
(Massachusetts Institute of Technology, 2003)
The iLab service broker : a software infrastructure providing common services in support of Internet accessible laboratories
(Massachusetts Institute of Technology, 2004)
Remote laboratories that are accessible via the Internet are becoming a common phenomenon in higher education institutions. This thesis describes the iLab Service Broker architecture, a software infrastructure that supports ...
A multiple secretary problem with switch costs
(Massachusetts Institute of Technology, 2007)
In this thesis, we utilize probabilistic reasoning and simulation methods to determine the optimal selection rule for the secretary problem with switch costs, in which a known number of applicants appear sequentially in a ...
Capacity provisioning, failure recovery and throughput analysis for low earth orbit satellite constellations
(Massachusetts Institute of Technology, 2002)
We investigate the capacity needed to build a restorable satellite network and design routing schemes to achieve high throughput. Specifically, the first part of this thesis considers the link capacity requirement for a ...
Establishing a positional information assay for brain ventricle mutants and investigating the choroid plexuses in zebrafish
(Massachusetts Institute of Technology, 2004)
The process by which the neural tube expands into three brain ventricles can be understood through genetic mutant analysis. Within the framework of a characterization of zebrafish mutants with brain ventricle phenotypes, ...
Inventory planning for low demand items in online retailing
(Massachusetts Institute of Technology, 2007)
A large online retailer strategically stocks inventory for SKUs with low demand. The motivations are to provide a wide range of selections and faster customer fulfillment service. We assume the online retailer has the ...
High-speed modulation of resonant CMOS photonic modulators in deep-submicron bulk-CMOS
(Massachusetts Institute of Technology, 2009)
Processor manufacturers have turned to parallelism to continue to improve processor performance, and the bandwidth demands of these systems have risen. Silicon photonics can lower the energy-per-bit of core-to-core and ...
Faster generation of random spanning trees
(Massachusetts Institute of Technology, 2009)
In this thesis, we set forth a new algorithm for generating approximately uniformly random spanning trees in undirected graphs. We show how to sample from a distribution that is within a multiplicative (1+6) of uniform in ...
An optical data receiver for integrated photonic interconnects
(Massachusetts Institute of Technology, 2009)
The throughput bounds of traditional interconnect networks in microprocessors are being pushed to their limits. In past single-core processors, the number of long global wires constituted only a small fraction of the total. ...
