  • Oskooi, Ardavan F (Massachusetts Institute of Technology, 2008)
    Although perfectly matched layers (PMLs) have been widely used to truncate numerical simulations of electromagnetism and other wave equations, we point out important cases in which a PML fails to be reflectionless even in ...
  • Mazumdar, Anupam, S.M. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2009)
    Price management, production planning and inventory control are important determinants of a firm's profitability. The intense competition brought about by rapid innovation, lean manufacturing time and the internet revolution ...
  • Bolin, Christopher E. (Christopher Eric) (Massachusetts Institute of Technology, 2013)
    Life cycle assessment (LCA) is one methodology for assessing a product's impact on the environment. LCA has grown in popularity recently as consumers and governments request more information concerning the environmental ...
  • Tupek, Michael Ronne (Massachusetts Institute of Technology, 2010)
    This thesis explores various Lagrangian methods for simulating ballistic impact with the ultimate goal of finding a universal, robust and scalable computational framework to assist in the design of armor systems. An overview ...
  • Diosady, Laslo Tibor (Massachusetts Institute of Technology, 2007)
    A Newton-Krylov method is developed for the solution of the steady compressible Navier-Stokes equations using a Discontinuous Galerkin (DG) discretization on unstructured meshes. An element Line-Jacobi preconditioner is ...
  • Tian, Shuo, S.M. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2010)
    The thesis aims to provide a way to identify better matches between buyers and suppliers who are using an e-procurement platform provided by a US based worldwide online market company. The goal is to enhance the shopping ...
  • Teo, Koon Soon (Massachusetts Institute of Technology, 2009)
    The loss of coordination in supply chains quantifies the inefficiency (i.e. the loss of total profit) due to the presence of competition in the supply chain. In this thesis, we discuss four models: one model with multiple ...
  • Sun, Jia Li, S.M. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2006)
    In this thesis, we investigate theoretical and numerical advantages of a novel representation for Sum of Squares (SOS) decomposition of univariate and multivariate polynomials. This representation formulates a SOS problem ...
  • Nan, Feng, S.M. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2009)
    We consider the problem of recovering a low rank matrix given a sampling of its entries. Such problems are of considerable interest in a diverse set of fields including control, system identification, statistics and signal ...
  • Rao, Tingting (Massachusetts Institute of Technology, 2008)
    It is important for companies to manage their revenues and -reduce their costs efficiently. These goals can be achieved through effective pricing and inventory control strategies. This thesis studies a joint multi-period ...
  • Ustun, Berk (Tevfik Berk) (Massachusetts Institute of Technology, 2012)
    Stochastic programming models are large-scale optimization problems that are used to facilitate decision-making under uncertainty. Optimization algorithms for such problems need to evaluate the expected future costs of ...
  • Yano, Masayuki, Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2009)
    A high-order Galerkin Least-Squares (GLS) finite element discretization is combined with massively parallel implicit solvers. The stabilization parameter of the GLS discretization is modified to improve the resolution ...
  • Biddle, Jason Charles (Massachusetts Institute of Technology, 2010)
    In this thesis, we summarize our work on applications and methods for computational protein design. First, we apply computational protein design to address the problem of degradation in stored proteins. Specifically, we ...
  • Wu, Kailiang (Massachusetts Institute of Technology, 2008)
    The semiconductor industry is an exciting and challenging industry. Strong demand at the application end, plus the high capital intensity and rapid technological innovation in manufacturing, makes it difficult to manage ...
  • Chen, Daizhuo (Massachusetts Institute of Technology, 2010)
    Uncertainty in travel time is one of the key factors that could allow us to understand and manage congestion in transportation networks. Models that incorporate uncertainty in travel time need to specify two mechanisms: ...
  • Zhang, Hui, S.M. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2009)
    The purpose of this project is to incorporate a Poisson disease model into the Spatiotemporal Epidemiological Modeler (STEM) and visualize the disease spread on Google Earth. It is done through developing a Poisson disease ...
  • Wogrin, Sonja (Massachusetts Institute of Technology, 2008)
    In many settings, distributed sensors provide dynamic measurements over a specified time horizon that can be used to reconstruct information such as parameters, states or initial conditions. This estimation task can be ...
  • Coles, Thomas Michael Kyte (Massachusetts Institute of Technology, 2011)
    This thesis investigates the impact of uncertainty on the reduction and simplification of chemical kinetics mechanisms. Chemical kinetics simulations of complex fuels are very computationally expensive, especially when ...
  • Ni, Yuzhao (Massachusetts Institute of Technology, 2013)
    In this thesis, we designed and implemented a crowdsourcing system to annotate mouse behaviors in videos; this involves the development of a novel clip-based video labeling tools, that is more efficient than traditional ...
  • 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 ...
