    • Mechanism and Transition-State Structures for Nickel-Catalyzed Reductive Alkyne−Aldehyde Coupling Reactions 

      McCarren, Patrick R.; Liu, Peng; Cheong, Paul Ha-Yeon; Jamison, Timothy F.; Houk, K. N. (American Chemical Society (ACS), 2009-04)
      The mechanism of nickel-catalyzed reductive alkyne−aldehyde coupling reactions has been investigated using density functional theory. The preferred mechanism involves oxidative cyclization to form the nickeladihydrofuran ...
    • Mechanism by which surfactants modify adipic acid crystal growth rate and habit 

      Tausch, Frederick W. (Frederick William), 1934- (Massachusetts Institute of Technology, 1961)
    • Mechanism design : a new algorithmic framework 

      Cai, Yang, Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2013)
      A modern engineering system, e.g. the Internet, faces challenges from both the strategic behavior of its self-interested participants and the inherent computational intractability of large systems. Responding to this ...
    • Mechanism design : from optimal transport theory to revenue maximization 

      Tzamos, Christos (Massachusetts Institute of Technology, 2017)
      A central problem in Economics and Algorithmic Game Theory is the design of auctions that maximize the auctioneer's expected revenue. While optimal selling of a single item has been well-understood since the pioneering ...
    • The Mechanism Design Approach to Student Assignment 

      Pathak, Parag (Annual Reviews, 2011-05)
      The mechanism design approach to student assignment involves the theoretical, empirical, and experimental study of systems used to allocate students into schools around the world. Recent practical experience designing ...
    • Mechanism design of a multi-motion automobile door 

      Edinger, Sarah T. (Sarah Tracy) (Massachusetts Institute of Technology, 2008)
      This thesis describes the design and prototype construction of a multi-motion automobile door. This design is intended to provide a unique option for the opening of an automobile by enabling the door to open in two separate ...
    • Mechanism Design via Optimal Transport 

      Daskalakis, Konstantinos; Deckelbaum, Alan; Tzamos, Christos (Association for Computing Machinery (ACM), 2013-06)
      Optimal mechanisms have been provided in quite general multi-item settings [Cai et al. 2012b, as long as each bidder's type distribution is given explicitly by listing every type in the support along with its associated ...
    • Mechanism Design With Approximate Player Types 

      Chiesa, Alessandro; Micali, Silvio; Zhu, Zeyuan Allen (2011-02-16)
      We investigate mechanism design when the players do not exactly know their types, but have instead only partial information about them.
    • Mechanism design with approximate types 

      Zhu, Zeyuan Allen (Massachusetts Institute of Technology, 2012)
      In mechanism design, we replace the strong assumption that each player knows his own payoff type exactly with the more realistic assumption that he knows it only approximately: each player i only knows that his true type ...
    • Mechanism Design with Approximate Valuations 

      Chiesa, Alessandro; Micali, Silvio; Zhu, Zeyuan Allen (2011-02-16)
      In mechanism design, we replace the strong assumption that each player knows his own payoff type EXACTLY with the more realistic assumption that he knows it only APPROXIMATELY. Specifically, we study the classical problem ...
    • Mechanism design with maxmin agents: Theory and an application to bilateral trade 

      Wolitzky, Alexander G. (The Econometric Society, 2016-09)
      This paper studies mechanism design when agents are maxmin expected utility maximizers. A first result gives a general necessary condition for a social choice rule to be implementable. The condition combines an inequality ...
    • Mechanism Design with Set-Theoretic Beliefs 

      Chen, Jing; Micali, Silvio (Institute of Electrical and Electronics Engineers (IEEE), 2011-12)
      In settings of incomplete information, we put forward (1) a very conservative -- indeed, purely set-theoretic -- model of the beliefs (including totally wrong ones) that each player may have about the payoff types of his ...
    • Mechanism design with set-theoretic beliefs 

      Chen, Jing, Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2012)
      In settings of incomplete information, we put forward: (1) a very conservative - indeed, purely set-theoretic- model of the beliefs (including totally wrong ones) that each player may have about the payoff types of his ...
    • Mechanism design with set-theoretic beliefs 

      Chen, Jing; Micali, Silvio (© IEEE, 2011-10-22)
      In settings of incomplete information, we put forward (1) a very conservative -- indeed, purely set-theoretic -- model of the beliefs (including totally wrong ones) that each player may have about the payoff types of his ...
    • Mechanism Dictates Mechanics: A Molecular Substituent Effect in the Macroscopic Fracture of a Covalent Polymer Network 

      Wang, Shu; Beech, Haley K; Bowser, Brandon H; Kouznetsova, Tatiana B; Olsen, Bradley D; e.a. (American Chemical Society (ACS), 2021)
      The fracture of rubbery polymer networks involves a series of molecular events, beginning with conformational changes along the polymer backbone and culminating with a chain scission reaction. Here, we report covalent ...
    • Mechanism for actuating seaweed harvesting device 

      Goul, Christopher. (Massachusetts Institute of Technology, 2019)
      Mechanical systems to automate a critical aspect of the seaweed farming process were designed and iterated to determine their feasibility as a substitute for human labor on a commercial large-scale seaweed farm. This paper ...
    • Mechanism for enhanced oxygen reduction kinetics at the (La,Sr)CoO3−δ/(La,Sr)2CoO4+δ hetero-interface 

      Han, Jeong Woo; Yildiz, Bilge (Royal Society of Chemistry, 2012-05)
      The recently reported fast oxygen reduction kinetics at the interface of (La,Sr)CoO3−δ (LSC113) and (La,Sr)2CoO4+δ (LSC214) phases opened up new questions for the potential role of dissimilar interfaces in advanced cathodes ...
