  • Fairness and optimality in trading 
    Nguyen, Van Vinh, S.M. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2010)
    This thesis proposes a novel approach to address the issues of efficiency and fairness when multiple portfolios are rebalanced simultaneously. A fund manager who rebalances multiple portfolios needs to not only optimize ...
  • A fast 3D full-wave solver for nanophotonics 
    Zhang, Lei, Ph. D. Massachusetts Institute of Technology. Department of Electrical Engineering and Computer Science. (Massachusetts Institute of Technology, 2007)
    Conventional fast integral equation solvers seem to be ideal approaches for simulating 3-D nanophotonic devices, as these devices are considered to be open structures, generating fields in both an interior channel and in ...
  • A fast enriched FEM for Poisson equations involving interfaces 
    Huynh, Thanh Le Ngoc (Massachusetts Institute of Technology, 2008)
    We develop a fast enriched finite element method for solving Poisson equations involving complex geometry interfaces by using regular Cartesian grids. The presence of interfaces is accounted for by developing suitable jump ...
  • Fully-kinetic PIC simulations for Hall-effect thrusters 
    Fox, Justin M., 1981- (Massachusetts Institute of Technology, 2007)
    In recent years, many groups have numerically modeled the near-anode region of a Hall thruster in attempts to better understand the associated physics of thruster operation. Originally, simulations assumed a continuum ...
  • Future characteristics of Offshore Support Vessels 
    Rose, Robin Sebastian Koske (Massachusetts Institute of Technology, 2011)
    The objective of this thesis is to examine trends in Offshore Support Vessel (OSV) design and determine the future characteristics of OSVs based on industry insight and supply chain models. Specifically, this thesis focuses ...
  • A generalized precorrected-FFT method for electromagnetic analysis 
    Leibman, Stephen Gerald (Massachusetts Institute of Technology, 2008)
    Boundary Element Methods (BEM) can be ideal approaches for simulating the behavior of physical systems in which the volumes have homogeneous properties. These, especially the so-called "fast" or "accelerated" BEM approaches ...
  • Graduate school introductory computational simulation course pedagogy 
    Proctor, Laura L. (Laura Lynne), 1975- (Massachusetts Institute of Technology, 2009)
    Numerical methods and algorithms have developed and matured vastly over the past three decades now that computational analysis can be performed on almost any personal computer. There is a need to be able to teach and present ...
  • High-dimensional design space visualization for conceptual structural design 
    Mueller, Caitlin T (Massachusetts Institute of Technology, 2014)
    This thesis focuses on visualizing high-dimensional design spaces for early-stage design problems in structural engineering and related disciplines. The design space, which is defined as the n + 1-dimensional surface that ...
  • Impact of carbon emission regulatory policies on the electricity market : a simulation study 
    Tiwari, Sandeep, S.M. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2010)
    With ever rising concerns regarding global warming and other dangerous effects of CO2 , there had been efforts to reduce CO2 emissions all around the world by adopting more efficient technologies and alternate green or ...
  • Impact of triangle shapes using high-order discretizations and direct mesh adaptation for output error 
    Sun, Huafei (Massachusetts Institute of Technology, 2009)
    The impact of triangle shapes, including angle sizes and aspect ratios, on accuracy and stiffness is investigated for simulations of highly anisotropic problems. The results indicate that for high-order discretizations, ...
  • Impacts of revenue management on estimates of spilled passenger demand 
    Abramovich, Michael (Massachusetts Institute of Technology, 2013)
    In the airline industry, spill refers to passenger demand turned away from a flight because demand has exceeded capacity. The accurate estimation of spill and the lost revenue it implies is an important parameter in airline ...
  • Improving the efficiency of an automated manufacturing system through a tri-part approach 
    Song, Chen, S.M. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2013)
    This research investigates a complex automated manufacturing system at three levels to improve its efficiency. In the system there are parallel loops of stations connected by a single closed conveyor. In each loop there ...
  • An investigation of the perfectly matched layer for inhomogeneous media 
    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 ...
  • Iterative algorithms for a joint pricing and inventory control problem with nonlinear demand functions 
    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 ...
  • Iterative uncertainty reduction via Monte Carlo simulation : a streamlined life cycle assessment case study 
    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 ...
  • Lagrangian methods for ballistic impact simulations/ 
    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 ...
  • A linear multigrid preconditioner for the solution of the Navier-Stokes equations using a discontinuous Galerkin discretization 
    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 ...
  • Logistic regression for a better matching of buyers and suppliers in e-procurement 
    Tian, Shuo, S.M. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2010)
