  • Multilevel spectral clustering : graph partitions and image segmentation 
    Kong, Tian Fook (Massachusetts Institute of Technology, 2008)
    While the spectral graph partitioning method gives high quality segmentation, segmenting large graphs by the spectral method is computationally expensive. Numerous multilevel graph partitioning algorithms are proposed to ...
  • Multi-objective constrained optimization for decision making and optimization for system architectures 
    Lin, Maokai (Massachusetts Institute of Technology, 2010)
    This thesis proposes new methods to solve three problems: 1) how to model and solve decision-making problems, 2) how to translate between a graphical representation of systems and a matrix representation of systems, and ...
  • Multi-parameter estimation in glacier models with adjoint and algorithmic differentiation 
    Davis, Andrew D. (Andrew Donaldson) (Massachusetts Institute of Technology, 2012)
    The cryosphere is comprised of about 33 million km³ of ice, which corresponds to 70 meters of global mean sea level equivalent [30]. Simulating continental ice masses, such as the Antarctic or Greenland Ice Sheets, requires ...
  • Multi-period optimal network flow and pricing strategy for commodity online retailer 
    Wang, Jie, S.M. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2009)
    This thesis aims to study the network of a nationwide distributor of a commodity product. As we cannot disclose the actual product for competitive reasons, we will present the research in terms of a similar, representative ...
  • Multi-period pricing for perishable products : uncertainty and competition 
    Zhang, Lei, Ph. D. Massachusetts Institute of Technology. Department Electrical Engineering and Computer Science. (Massachusetts Institute of Technology, 2006)
    The pricing problem in a multi-period setting is a challenging problem and has attracted much attention in recent years. In this thesis, we consider a monopoly and an oligopoly pricing problem. In the latter, several sellers ...
  • A multiple secretary problem with switch costs 
    Ding, Jiachuan (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 ...
  • Multiscale Dynamic Time and Space Warping 
    Fitriani (Massachusetts Institute of Technology, 2008)
    Dynamic Time and Space Warping (DTSW) is a technique used in video matching applications to find the optimal alignment between two videos. Because DTSW requires O(N4) time and space complexity, it is only suitable for short ...
  • A multiscale framework for Bayesian inference in elliptic problems 
    Parno, Matthew David (Massachusetts Institute of Technology, 2011)
    The Bayesian approach to inference problems provides a systematic way of updating prior knowledge with data. A likelihood function involving a forward model of the problem is used to incorporate data into a posterior ...
  • Must linear algebra be block cyclic? : and other explorations into the expressivity of data parallel and task parallel languages 
    Sundaresh, Harish Peruvamba (Massachusetts Institute of Technology, 2007)
    Prevailing Parallel Linear Algebra software block cyclically distributes data across its processors for good load balancing and communication between its nodes. The block cyclic distribution schema characterized by cyclic ...
  • Network security and min-cost max-flow problem 
    Dahan, Mathieu (Massachusetts Institute of Technology, 2016)
    Network optimization has widely been studied in the literature for a variety of design and operational problems. This has resulted in the development of computational algorithms for the study of classical operations research ...
  • A nonsmooth exclusion test for finding all solutions of nonlinear equations 
    Kumar, Vinay, S.M. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2007)
    A new approach is proposed for finding all solutions of systems of nonlinear equations with bound constraints. The zero finding problem is converted to a global optimization problem whose global minima with zero objective ...
  • Numerical approaches to optimize dispatch on microgrids with energy storage 
    Xie, Lutao (Massachusetts Institute of Technology, 2016)
    Microgrids and distributed generation are predicted to become extremely dominant in developing nations, and will be largely beneficial to both electricity suppliers and consumers. With the penetration of renewable energy ...
  • Numerical simulations of perforated plate stabilized premixed flames with detailed chemistry 
    Kedia, Kushal Sharad (Massachusetts Institute of Technology, 2010)
    The objective of this work is to develop a high efficiency two-dimensional reactive flow solver to investigate perforated-plate stabilized laminar premixed flames. The developed code is used to examine the impact of the ...
  • On the computation of probabilities and eigenvalues for random and non-random matrices 
    Peruvamba Sundaresh, Vignesh (Massachusetts Institute of Technology, 2009)
    Can you imagine doing hundreds of millions of operations on non-integers and not obtaining a single round-off error? For n < 12, the algorithm used in this thesis does exactly that. We took advantage of a floating point ...
  • On the effect and value of information in Bayesian routing games 
    Liu, Jeffrey, S.M. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2015)
    We consider the problem of estimating individual and social value of information in routing games. We propose a Bayesian congestion game that accounts for the heterogeneity in the commuters' access to information about ...
  • On the Gap-Tooth direct simulation Monte Carlo method 
    Armour, Jessica D (Massachusetts Institute of Technology, 2012)
    This thesis develops and evaluates Gap-tooth DSMC (GT-DSMC), a direct Monte Carlo simulation procedure for dilute gases combined with the Gap-tooth method of Gear, Li, and Kevrekidis. The latter was proposed as a means of ...
  • On the predictive capability and stability of rubber material models 
    Zheng, Haining (Massachusetts Institute of Technology, 2008)
    Due to the high non-linearity and incompressibility constraint of rubber materials, the predictive capability and stability of rubber material models require specific attention for practical engineering analysis. In this ...
  • Optimal approximations of coupling in multidisciplinary models 
    Santos Baptista, Ricardo Miguel (Massachusetts Institute of Technology, 2017)
    Design of complex engineering systems requires coupled analyses of the multiple disciplines affecting system performance. The coupling among disciplines typically contributes significantly to the computational cost of ...
  • Optimal Bayesian experimental design in the presence of model error 
    Feng, Chi, S.M. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2015)
