  • Fowlie, Meredith; Knittel, Christopher Roland; Wolfram, Catherine (American Economic Association, 2012-02)
    For political and practical reasons, environmental regulations sometimes treat point-source polluters, such as power plants, differently from mobile-source polluters, such as vehicles. This paper measures the extent of ...
  • Palde, Prakash B.; Jamison, Timothy F. (Wiley Blackwell, 2011-03)
    Safer flow: The synthesis of 5-substituted tetrazoles in flow (see scheme) is safe, efficient, scalable, requires no metal promoter, and uses a near-equimolar amount of NaN[subscript 3], yet nonetheless displays a broad ...
  • Yun, Seung-kook; Goswami, Ambarish; Sakagami, Yoshiaki (Institute of Electrical and Electronics Engineers (IEEE), 2009-08)
    Although fall is a rare event in the life of a humanoid robot, we must be prepared for it because its consequences are serious. In this paper we present a fall strategy which rapidly modifies the robot's fall direction in ...
  • Verma, Rajeev; Del Vecchio, Domitilla (Institute of Electrical and Electronics Engineers, 2011-12)
    In this paper, we consider the safety control problem for hidden mode hybrid systems (HMHSs), which are a special class of hybrid automata in which the mode is not available for control. For these systems, safety control ...
  • Ghaemi, Reza; Del Vecchio, Domitilla (Institute of Electrical and Electronics Engineers, 2011-12)
    This paper is concerned with safety control of systems with imperfect state information and disturbance input. Specifically, we consider the class of systems whose dynamics preserve a partial ordering. We provide necessary ...
  • Stringfellow, Margaret V.; Leveson, Nancy G.; Owens, Brandon D. (Institute of Electrical and Electronics Engineers, 2010-03)
    Too often, systems are designed and then an attempt is made to add safety features or to prove that the design is safe after the fact. Safety has to be designed into a system from the start-it cannot be effectively added ...
  • Markovits, Julia (Springer Science + Business Media B.V., 2012-03)
    This essay explores the question of how to be good. My starting point is a thesis about moral worth that I’ve defended in the past: roughly, that an action is morally worthy if and only it is performed for the reasons ...
  • Richmond, Christ D.; Movassagh, Ramis; Movassagh, Ramis; Edelman, Alan (Institute of Electrical and Electronics Engineers (IEEE), 2011-04)
    The method of interval estimation (MIE) provides a strategy for mean squared error (MSE) prediction of algorithm performance at low signal-to-noise ratios (SNR) below estimation threshold where asymptotic predictions fail. ...
  • Frazzoli, Emilio; Karaman, Sertac (Institute of Electrical and Electronics Engineers, 2010-01)
    In this paper, we propose algorithms for the on-line computation of control programs for dynamical systems that provably satisfy a class of temporal logic specifications. Such specifications have recently been proposed in ...

  • Aoude, Georges; How, Jonathan P.; Luders, Brandon Douglas; Pilutti, Tom E. (2010-09)
    This paper considers the decision-making problem for a vehicle crossing a road intersection in the presence of other, potentially errant, drivers. This problem is considered in a game-theoretic framework, where the errant ...
  • Chen, Meng; Wan, Yehong; Ade, Kristen; Ting, Jonathan; Feng, Guoping; Calakos, Nicole (Society for Neuroscience, 2011-06)
    Retrograde synaptic signaling by endocannabinoids (eCBs) is a widespread mechanism for activity-dependent inhibition of synaptic strength in the brain. Although prevalent, the conditions for eliciting eCB-mediated synaptic ...
  • Surussavadee, Chinnawat; Staelin, David H. (Institute of Electrical and Electronics Engineers, 2009-10)
    A new global precipitation retrieval algorithm for the millimeter-wave Advanced Microwave Sounding Unit is presented that also retrieves Arctic precipitation rates over surface snow and ice. This algorithm improves upon ...
  • Bühler, Oliver; Muller, Caroline (American Meteorological Society, 2009-01)
    As part of an ongoing effort to develop a parameterization of wave-induced abyssal mixing, the authors derive an heuristic model for nonlinear wave breaking and energy dissipation associated with internal tides. Then the ...
  • Amsden, Alice H. (Routledge, 2010-02)
  • Thomson, Ty M.; Benjamin, Kirsten R.; Bush, Alan; Love, Tonya; Pincus, David; Resnekov, Orna; Yu, Richard C.; Gordon, Andrew; Colman-Lerner, Alejandro; Endy, Drew; Brent, Roger (National Academy of Sciences, 2011-12)
    Although the proteins comprising many signaling systems are known, less is known about their numbers per cell. Existing measurements often vary by more than 10-fold. Here, we devised improved quantification methods to ...
  • Kim, Dae-Hyun; del Alamo, Jesus A. (Institute of Electrical and Electronics Engineers (IEEE), 2010-06)
    We have experimentally studied the scaling behavior of sub-100-nm InAs high-electron mobility transistors (HEMTs) on InP substrate from the logic operation point of view. These devices have been designed for scalability ...
  • del Alamo, Jesus A.; Kim, Dae-Hyun (Institute of Electrical and Electronics Engineers, 2009-05)
    We have experimentally investigated the role of thinning down the channel thickness and using high InAs composition as a channel material, which aims to improve the electrostatic integrity of the device as well as high ...
  • Lis, Mieszko; Ren, Pengju; Cho, Myong Hyo; Shim, Keun Sup; Fletcher, Christopher Wardlaw; Khan, Omer; Devadas, Srinivas (Institute of Electrical and Electronics Engineers (IEEE), 2011-05)
    We present HORNET, a parallel, highly configurable, cycle-level multicore simulator based on an ingress-queued worm-hole router NoC architecture. The parallel simulation engine offers cycle-accurate as well as periodic ...
  • Clements, Austin T.; Kaashoek, M. Frans; Zeldovich, Nickolai (Association for Computing Machinery (ACM), 2012-03)
    Software developers commonly exploit multicore processors by building multithreaded software in which all threads of an application share a single address space. This shared address space has a cost: kernel virtual memory ...
