  • Stochastic Digital Circuits for Probabilistic Inference 

    Unknown author (2008-11-24)
    We introduce combinational stochastic logic, an abstraction that generalizes deterministic digital circuit design (based on Boolean logic gates) to the probabilistic setting. We show how this logic can be combined with ...

  • Modeling Computational Security in Long-Lived Systems, Version 2 

    Unknown author (2008-11-22)
    For many cryptographic protocols, security relies on the assumption that adversarial entities have limited computational power. This type of security degrades progressively over the lifetime of a protocol. However, some ...

  • Resilient Mechanisms For Truly Combinatorial Auctions 

    Unknown author (2008-11-13)
    Dominant-strategy truthfulness is traditionally considered the best possible solution concept in mechanism design, as it enables one to predict with confidence which strategies INDEPENDENT players will actually choose. ...

  • MOOS-IvP Autonomy Tools Users Manual 

    Unknown author (2008-11-11)
    This document describes seven common MOOS-IvP autonomy tools. The uHelmScope application provides a run-time scoping window into the state of an active IvP Helm executing its mission. The pMarineViewer application is a ...

  • Energy Scalability of On-Chip Interconnection Networks in Multicore Architectures 

    Unknown author (2008-11-11)
    On-chip interconnection networks (OCNs) such as point-to-point networks and buses form the communication backbone in systems-on-a-chip, multicore processors, and tiled processors. OCNs can consume significant portions of ...

  • Recursively invoking Linnaeus: A Taxonomy for Naming Systems 

    Unknown author (2002-03-01)
    Naming is a central element of a distributed or network system design. Appropriate design choices are central. This paper explores a taxonomy of naming systems, and engineering tradeoffs as an aid to the namespace designer. ...

  • One Video Stream to Serve Diverse Receivers 

    Unknown author (2008-10-18)
    The fundamental problem of wireless video multicast is to scalably serve multiple receivers which may have very different channel characteristics. Ideally, one would like to broadcast a single stream that allows each ...

  • Adaptive Kernel Methods Using the Balancing Principle 

    Unknown author (2008-10-16)
    The regularization parameter choice is a fundamental problem in supervised learning since the performance of most algorithms crucially depends on the choice of one or more of such parameters. In particular a main theoretical ...

  • Modular Generation and Customization 

    Unknown author (2008-10-10)
    Modularity and flexibility can conflict in multi-language systems. For example, the templates commonly used to generate web pages must be manually updated when the database schema changes. Modularity can be improved by ...

  • The Case for a Factored Operating System (fos) 

    Unknown author (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 ...

  • New Resiliency in Truly Combinatorial Auctions (and Implementation in Surviving Strategies) 

    Unknown author (2008-10-08)
    Following Micali and Valiant [MV07.a], a mechanism is resilient if it achieves its objective without any problem of (1) equilibrium selection and (2) player collusion. To advance resilient mechanism design,We put forward ...

  • ZigZag Decoding: Combating Hidden Terminals In Wireless Networks 

    Unknown author (2008-10-01)
    This paper presents ZigZag, an 802.11 receiver design that combats hidden terminals. ZigZag's core contribution is a new form of interference cancellation that exploits asynchrony across successive collisions. Specifically, ...

  • Refactoring Sequential Java Code for Concurrency via Concurrent Libraries 

    Unknown author (2008-09-30)
    Parallelizing existing sequential programs to run efficiently on multicores is hard. The Java 5 packagejava.util.concurrent (j.u.c.) supports writing concurrent programs: much of the complexity of writing threads-safe and ...

  • Rank Priors for Continuous Non-Linear Dimensionality Reduction 

    Unknown author (2008-09-26)
    Non-linear dimensionality reduction methods are powerful techniques to deal with high-dimensional datasets. However, they often are susceptible to local minima and perform poorly when initialized far from the global optimum, ...

  • Stochastic Combinatorial Optimization with Risk 

    Unknown author (2008-09-13)
    We consider general combinatorial optimization problems that can be formulated as minimizing the weight of a feasible solution wT x over an arbitrary feasible set. For these problems we describe a broad class of corresponding ...

  • Automatic Creation of SQL Injection and Cross-Site Scripting Attacks 

    Michael Ernst; Program Analysis (2008-09-10)
    We present a technique for finding security vulnerabilitiesin Web applications. SQL Injection (SQLI) and cross-sitescripting (XSS) attacks are widespread forms of attackin which the attacker crafts the input to the application ...

  • How do programs become more concurrent? A story of program transformations 

    Michael Ernst; Program Analysis (2008-09-05)
    For several decades, programmers have relied onMooreâ s Law to improve the performance of their softwareapplications. From now on, programmers need to programthe multi-cores if they want to deliver efficient code. Inthe ...

  • Style Translation for Human Motion (Supplemental Material) 

    Jovan Popovic; Computer Graphics (2005-08-01)
    Style translation is the process of transforming an input motion into a new style while preserving its original content. This problem is motivated by the needs of interactive applications, which require rapid processing ...

  • Interactive Simulation of Stylized Human Locomotion 

    Jovan Popovic; Computer Graphics (2008-08-01)
    Animating natural human motion in dynamic environments is difficult because of complex geometric and physical interactions. Simulation provides an automatic solution to parts of this problem, but it needs control systems ...
