    • A tactical planning model for a serial flow manufacturing system 

      Huang, Bin, S.M. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2010)
      This project aims to improve the operation and planning of a specific type of manufacturing system, a serial flow line that entails a sequence of process stages. The objective is to investigate inventory policy, raw material ...
    • Tensor decomposition and parallelization of Markov Decision Processes 

      Smart, David P. (David Paul) (Massachusetts Institute of Technology, 2016)
      Markov Decision Processes (MDPs) with large state spaces arise frequently when applied to real world problems. Optimal solutions to such problems exist, but may not be computationally tractable, as the required processing ...
    • Testing for jumps and cojumps in financial markets 

      Ju, Cheng, S.M. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2010)
      In this thesis, we introduce a new testing methodology to detect cojumps in multi-asset returns. We define a cojump as a jump in at least one dimension of the return processes. For a multivariate process that follows a ...
    • A thread-based parallel programming library for numerical algorithms 

      Alhubail, Maitham Makki (Maitham Makki Hussain) (Massachusetts Institute of Technology, 2014)
      This thesis presents a new simple lightweight C++ thread based parallelization library, intended for use in numerical algorithms. It provides simple multitasking and task synchronization functions. The library hides all ...
    • The (travel) times they are a changing : a computational framework for the diagnosis of non-alcoholic fatty liver disease (NAFLD) 

      Benjamin, Alex (Alex Robert) (Massachusetts Institute of Technology, 2017)
      We propose and validate a non-invasive method to diagnose Non-Alcoholic Fatty Liver Disease (NAFLD). The proposed method is based on two fundamental concepts: 1) the speed of sound in a fatty liver is lower than that in a ...
    • Understanding and modeling human movement in cities using phone data 

      Alhasoun, Fahad (Massachusetts Institute of Technology, 2016)
      Cities today are strained by the exponential growth in population where they are homes to the majority of world's population. Understanding the complexities underlying the emerging behaviors of human travel patterns on the ...
    • An unstructured finite volume simulator for multiphase flow through fractured-porous media 

      Bajaj, Reena (Massachusetts Institute of Technology, 2009)
      Modeling of multiphase flow in fractured media plays an integral role in management and performance prediction of oil and gas reserves. Geological characterization and nmultiphase flow simulations in fractured media are ...
    • Untangling the effects of residential segregation on individual mobility 

      Desu, Suma (Massachusetts Institute of Technology, 2015)
      More than half of today's world population lives in cities and that fraction is steadily growing. Models that accurately capture all segments of the population are necessary in order to design effective policies and new ...
    • Value of heterogeneous information in stochastically congestible facilities 

      Khan, Zaid S. (Zaid Saeed) (Massachusetts Institute of Technology, 2017)
      This thesis studies the effects of heterogeneous information on traffic equilibria and the resulting travel costs (both individual and social) when commuters make departure time choices to cross an unreliable bottleneck ...
    • Variational constitutive updates for strain gradient isotropic plasticity 

      Qiao, Lei, Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2009)
      In the past decades, various strain gradient isotropic plasticity theories have been developed to describe the size-dependence plastic deformation mechanisms observed experimentally in micron-indentation, torsion, bending ...
