Value-Deviation-Bounded Serial Data Encoding for Energy-Efficient Approximate Communication
(2015-06-04)Transferring data between ICs accounts for a growing proportion of system power in wearable and mobile systems. Reducing signal transitions reduces the dynamic power dissipated in this data transfer, but traditional ... -
Verifiably Secure Devices
(2007-12-05)We put forward the notion of a verifiably secure device, in essence a stronger notion of secure computation, and achieve it in the ballot-box model. Verifiably secure devices1. Provide a perfect solution to the problem of ... -
Verification of Semantic Commutativity Conditions and Inverse Operations on Linked Data Structures
(2010-12-03)Commuting operations play a critical role in many parallel computing systems. We present a new technique for verifying commutativity conditions, which are logical formulas that characterize when operations commute. Because ... -
Verifying Quantitative Reliability of Programs That Execute on Unreliable Hardware
(2013-06-19)Emerging high-performance architectures are anticipated to contain unreliable components that may exhibit soft errors, which silently corrupt the results of computations. Full detection and recovery from soft errors is ... -
Verifying the Correctness of Wide-Area Internet Routing
(2004-05-17)Several studies have shown that wide-area Internet routing is fragile, with failures occurring for a variety of reasons. Routing fragility is largely due to the flexible and powerful ways in which BGP can be configured to ... -
Versatility and VersaBench: A New Metric and a Benchmark Suite for Flexible Architectures
(2004-06-14)For the last several decades, computer architecture research has largely benefited from, and continues to be driven by ad-hoc benchmarking. Often the benchmarks are selected to represent workloads that architects believe ... -
Victim Migration: Dynamically Adapting Between Private and Shared CMP Caches
(2005-10-10)Future CMPs will have more cores and greater onchip cache capacity. The on-chip cache can either be divided into separate private L2 caches for each core, or treated as a large shared L2 cache. Private caches provide low ... -
Video Matching
(2004-05-11)This paper describes a method for bringing two videos (recorded at different times) into spatiotemporal alignment, then comparing and combining corresponding pixels for applications such as background subtraction, compositing, ... -
The Video Mesh: A Data Structure for Image-based Video Editing
(2009-12-16)This paper introduces the video mesh, a data structure for representing video as 2.5D "paper cutouts." The video mesh allows interactive editing of moving objects and modeling of depth, which enables 3D effects and ... -
Viewstamped Replication Revisited
(2012-07-23)This paper presents an updated version of Viewstamped Replication, a replication technique that handles failures in which nodes crash. It describes how client requests are handled, how the group reorganizes when a replica ... -
Virtual Mobile Nodes for Mobile Ad Hoc Networks
(2004-02-26)One of the most significant challenges introduced by mobile networks is the difficulty in coping withthe unpredictable movement of mobile nodes. If, instead, the mobile nodes could be programmed totravel through the world ... -
Virtual Monotonic Counters and Count-Limited Objects using a TPM without a Trusted OS (Extended Version)
(2006-09-11)A trusted monotonic counter is a valuable primitive thatenables a wide variety of highly scalable offlineand decentralized applications that would otherwise be prone to replay attacks, including offline payment, e-wallets, ... -
Virtual Stationary Automata for Mobile Networks
(2005-01-21)We define a programming abstraction formobile networks called the Virtual Stationary Automataprogramming layer, consisting of real mobile clients, virtualtimed I/O automata called virtual stationary automata(VSAs), and a ... -
Virtual Visual Hulls: Example-Based 3D Shape Estimation from a Single Silhouette
(2004-01-28)Recovering a volumetric model of a person, car, or other objectof interest from a single snapshot would be useful for many computergraphics applications. 3D model estimation in general is hard, andcurrently requires active ... -
Vote the OS off your Core
(2011-07-27)Recent trends in OS research have shown evidence that there are performance benefits to running OS services on different cores than the user applications that rely on them. We quantitatively evaluate this claim in terms ... -
Wait-free Regular Storage from Byzantine Components
(2005-04-05)We present a simple, efficient, and self-contained construction of a wait-free regular register from Byzantine storage components. Our construction utilizes a novel building block, called 1-regular register, which can be ... -
Was the Patient Cured? Understanding Semantic Categories and Their Relationships in Patient Records
(2006-06-28)In this thesis, we detail an approach to extracting key information in medical discharge summaries. Starting with a narrative patient report, we first identify and remove information that compromises privacy (de-identifi ... -
WaveScript: A Case-Study in Applying a Distributed Stream-Processing Language
(2008-01-31)Applications that combine live data streams with embedded, parallel,and distributed processing are becoming more commonplace. WaveScriptis a domain-specific language that brings high-level, type-safe,garbage-collected ... -
Werner Reichardt: the man and his scientific legacy
(2011-03-04)Excerpts from a talk given by Tomaso Poggio in Tübingen on the opening ofthe Werner Reichardt Centrun für Integrative Neurowissenschaften, December 8, 2008. -
Whanaungatanga: Sybil-proof routing with social networks
(2009-09-24)Decentralized systems, such as distributed hash tables, are subject to the Sybil attack, in which an adversary creates many false identities to increase its influence. This paper proposes a routing protocol for a distributed ...
