Semidenite representations with applications in estimation and inference
(Massachusetts Institute of Technology, 2015)
Semidenite optimization problems are an expressive family of convex optimization problems that can be solved eciently. We develop semidenite optimization-based formulations and approximations for a number of families of ...
On control and optimization of cascading phenomena in a class of dynamic networks
(Massachusetts Institute of Technology, 2015)
The primary goal of this thesis is to study transmission line reactance tweaking, as a mechanism for both post-disturbance control and pre-disturbance resilience enhancement in a transmission network, and develop an ...
Logical reasoning for approximate and unreliable computation
(Massachusetts Institute of Technology, 2015)
Improving program performance and resilience are long-standing goals. Traditional approaches include a variety of transformation, compilation, and runtime techniques that share the common property that the resulting program ...
Superconducting nanowire single-photon detectors : new detector architectures and integration with photonic chips
(Massachusetts Institute of Technology, 2015)
Superconducting nanowire single-photon detectors (SNSPDs) are a promising technology for long-distance optical communication and quantum information processing. Recent advances in single-photon generation, storage and ...
Power and limitations of convex formulations via linear and semidefinite programming lifts
(Massachusetts Institute of Technology, 2016)
Convex relaxation methods play an important role in mathematical optimization to tackle hard nonconvex problems, and have been applied successfully in many areas of science and engineering. At the heart of such methods ...
An integrated CRISPR-Cas toolkit for engineering human cells
(Massachusetts Institute of Technology, 2015)
Natively functioning Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-associated (Cas) system is a prokaryotic adaptive immune system that confers resistance to foreign genetic elements including plasmids ...
Discovering physics and design trends from visual temporal structures
(Massachusetts Institute of Technology, 2017)
Living in a constantly changing world, we cannot help but notice the temporal regularities of visual changes around us. These changes can be irreversible governed by physical laws, such as glass bottles broken into pieces, ...
Electronic systems for interfacing with new materials and devices
(Massachusetts Institute of Technology, 2015)
The focus of this thesis is to explore and demonstrate electronics systems utilizing new materials and devices beyond the traditional ones solely based on Si CMOS technology. The first part of this thesis is to explore the ...
Network management and control of flow-switched optical networks : joint architecture design and analysis of control plane and data plane with physical-layer impairments
(Massachusetts Institute of Technology, 2014)
Optical Flow Switching (OFS) that employs agile end-to-end lightpath switching for users with large transactions has been shown to be cost-effective and energy-efficient. However, whether it is possible to coordinate ...
Uplift modeling for randomized experiments and observational studies
(Massachusetts Institute of Technology, 2018)
Uplift modeling refers to the problem where we need to identify from a set of treatments the candidate that leads to the most desirable outcome based on subject characteristics. Most work in the last century focus on the ...
