  • Cabernet: A Content Delivery Network for Moving Vehicles 
    Eriksson, Jakob; Balakrishnan, Hari; Madden, Sam (2008-01-17)
    This paper describes the design, implementation, and evaluation of Cabernet, a system to deliver data to and from moving vehicles using open 802.11 (WiFi) access points encountered opportunistically during travel. Network ...
  • Cache Calculus: Modeling Caches through Differential Equations 
    Beckmann, Nathan; Sanchez, Daniel (2015-12-19)
    Caches are critical to performance, yet their behavior is hard to understand and model. In particular, prior work does not provide closed-form solutions of cache performance, i.e. simple expressions for the miss rate of a ...
  • A Cache Model for Modern Processors 
    Beckmann, Nathan; Sanchez, Daniel (2015-04-09)
    Modern processors use high-performance cache replacement policies that outperform traditional alternatives like least-recently used (LRU). Unfortunately, current cache models use stack distances to predict LRU or its ...
  • CADR 
    Knight, Thomas F., Jr.; Moon, David A.; Holloway, Jack; Steele, Guy L., Jr. (1979-05-01)
    The CADR machine, a revised version of the CONS machine, is a general-purpose, 32-bit microprogrammable processor which is the basis of the Lisp-machine system, a new computer system being developed by the Laboratory ...
  • The Calcomp Plotter as an Output Device 
    Speciner, Michael (1967-07-01)
    (1)CHAR PLOT (see AI Memo 125) has been modified for TS. [It may be found on MS4 with the non-TS version]. The following changes should be noted: CRKBRK (now called PLTBRK in the non-TS CHAR PLOT), SUBPLT (which is ...
  • Calculating the Reflectance Map 
    Horn, Berthold K.P.; Sjoberg, Robert W. (1978-10-01)
    It appears that the development of machine vision may benefit from a detailed understanding of the imaging process. The reflectance map, showing scene radiance as a function of surface gradient, has proved to be helpful ...
  • Calculation of Blocking Probabilities in Multistage Interconnection Networks with Redundant Paths 
    Sobalvarro, Patrick G. (1991-12-01)
    The blocking probability of a network is a common measure of its performance. There exist means of quickly calculating the blocking probabilities of Banyan networks; however, because Banyan networks have no redundant ...
  • Can Basic ML Techniques Illuminate Rateless Erasure Codes? 
    Gupta, Anjali; Krohn, Maxwell; Walfish, Michael (2004-05-05)
    The recently developed rateless erasure codes are a near-optimal channel coding technique that guaranteeslow overhead and fast decoding. The underlying theory, and current implementations, of thesecodes assume that a network ...
  • Capacity Allocation in Wireless LANs 
    Tan, Godfrey; Guttag, John (2004-11-12)
    Today's access point based wireless LANs (WLANs) are inefficient and unfair. For many traffic loads they provide far less total throughput than they should, and do a poor job allocating what throughput they do deliver. ...
  • CAPRI: A Common Architecture for Distributed Probabilistic Internet Fault Diagnosis 
    Lee, George J. (2007-06-04)
    This thesis presents a new approach to root cause localization and fault diagnosis in the Internet based on a Common Architecture for Probabilistic Reasoning in the Internet (CAPRI) in which distributed, heterogeneous ...
  • Capture It, Name It, Own it: How to capture re-occurring patterns, name them and turn them into reusable functions via Emacs kbd-macros 
    Kozlowski, Stefan N. (MIT Artificial Intelligence Laboratory, 1992-05)
    The purpose of this talk is not to teach you about Emacs or Emacs kbd-macros, though we will use both as examples. I can teach you everything there is to know about Emacs and kbd-macros in 5 minutes. There are literally ...
  • Capturing Intuitive Knowledge in Procedural Description 
    Bamberger, Jeanne (1976-12-01)
    Trying to capture intuitive knowledge is a little like trying to capture the moment between what just happened and what is about to happen. Or to quote a famous philosopher, "You can't put your foot in the same river ...
  • CARPS: A Program which Solves Calculus Word Problems 
    Charniak, Eugene (1968-07-01)
    A program was written to solve calculus word problems. The program, CARPS (CALculus Rate Problem Solver), is restricted to rate problems. The overall plan of the program is similar to Bobrow's STUDENT, the primary ...
  • CARTOON: A Biologically Motivated Edge Detection Algorithm 
    Richards, W.; Nishihara, H.K.; Dawson, B. (1982-06-01)
    Caricatures demonstrate that only a few significant "edges" need to be captured to convey the meaning of a complex pattern of image intensities. The most important of these "edges" are image intensity changes arising ...
  • Cascading Regularized Classifiers 
    Perez-Breva, Luis (2004-04-21)
    Among the various methods to combine classifiers, Boosting was originally thought as an stratagem to cascade pairs of classifiers through their disagreement. I recover the same idea from the work of Niyogi et al. to show ...
  • The Case for a Factored Operating System (fos) 
    Agarwal, Anant; Wentzlaff, David (2008-10-08)
    The next decade will afford us computer chips with 1,000 - 10,000 cores on a single piece of silicon. Contemporary operating systems have been designed to operate on a single core or small number of cores and hence are not ...
  • A Case for Fine-Grain Adaptive Cache Coherence 
    Kurian, George; Khan, Omer; Devadas, Srinivas (2012-05-22)
    As transistor density continues to grow geometrically, processor manufacturers are already able to place a hundred cores on a chip (e.g., Tilera TILE-Gx 100), with massive multicore chips on the horizon. Programmers now ...
  • A Case Study of a Young Child Doing Turtle Graphics in LOGO 
    Solomon, Cynthia J.; Papert, Seymour A. (1976-07-01)
    This paper explores some important issues with regard to using computers in education. It probes into the question of what programming ideas and projects will engage young children. In particular, a seven year old ...
  • Categorization in IT and PFC: Model and Experiments 
    Knoblich, Ulf; Freedman, David J.; Riesenhuber, Maximilian (2002-04-18)
    In a recent experiment, Freedman et al. recorded from inferotemporal (IT) and prefrontal cortices (PFC) of monkeys performing a "cat/dog" categorization task (Freedman 2001 and Freedman, Riesenhuber, Poggio, Miller ...
  • CAULDRONS: An Abstraction for Concurrent Problem Solving 
    Haase, Ken (1986-09-01)
    This research extends a tradition of distributed theories of mind into the implementation of a distributed problem solver. In this problem solver a number of ideas from Minsky's Society of Mind are implemented and are ...
