RingScalar: A Complexity-Effective Out-of-Order Superscalar Microarchitecture
(2006-09-18)RingScalar is a complexity-effective microarchitecture for out-of-order superscalar processors, that reduces the area, latency, and power of all major structures in the instruction flow. The design divides an N-way ... -
Risk Allocation for Multi-agent Systems using Tatonnement
(2009-04-22)This paper proposes a new market-based distributed planning algorithm for multi-agent systems under uncertainty, called MIRA (Market-based Iterative Risk Allocation). In large coordination problems, from power grid management ... -
Risk Allocation for Temporal Risk Assessment
(2013-01-31)Temporal uncertainty arises when performing any activity in the natural world. When activities are composed into temporal plans, then, there is a risk of not meeting the plan requirements. Currently, we do not have ... -
Risk Bounds for Mixture Density Estimation
(2004-01-27)In this paper we focus on the problem of estimating a boundeddensity using a finite combination of densities from a givenclass. We consider the Maximum Likelihood Procedure (MLE) and the greedy procedure described by Li ... -
Risk Bounds for Regularized Least-squares Algorithm with Operator-valued kernels
(2005-05-16)We show that recent results in [3] on risk bounds for regularized least-squares on reproducing kernel Hilbert spaces can be straightforwardly extended to the vector-valued regression setting. We first briefly introduce ... -
Risk-minimizing program execution in robotic domains
(2012-02-02)In this thesis, we argue that autonomous robots operating in hostile and uncertain environments can improve robustness by computing and reasoning explicitly about risk. Autonomous robots with a keen sensitivity to risk can ... -
Robot Manipulation in Human Environments
(2007-01-16)Human environments present special challenges for robot manipulation. They are often dynamic, difficult to predict, and beyond the control of a robot engineer. Fortunately, many characteristics of these settings can be ... -
Robust Execution of Bipedal Walking Tasks From Biomechanical Principles
(2006-04-28)Effective use of robots in unstructured environments requires that they have sufficient autonomy and agility to execute task-level commands successfully. A challenging example of such a robot is a bipedal walking machine. ... -
Robust Tracking for Real-Time Dense RGB-D Mapping with Kintinuous
(2012-09-17)This paper describes extensions to the Kintinuous algorithm for spatially extended KinectFusion, incorporating the following additions: (i) the integration of multiple 6DOF camera odometry estimation methods for robust ... -
Robust, Goal-directed Plan Execution with Bounded Risk
(2012-02-02)There is an increasing need for robust optimal plan execution for multi-agent systems in uncertain environments, while guaranteeing an acceptable probability of success. For ex- ample, a fleet of unmanned aerial vehicles ... -
Rosebud: A Scalable Byzantine-Fault-Tolerant Storage Architecture
(2003-12-17)This paper presents Rosebud, a new Byzantine faulttolerantstorage architecture designed to be highly scalableand deployable in the wide-area. To support massiveamounts of data, we need to partition the data among thenodes. ... -
Rotation Invariant Object Recognition from One Training Example
(2004-04-27)Local descriptors are increasingly used for the task of object recognition because of their perceived robustness with respect to occlusions and to global geometrical deformations. Such a descriptor--based on a set of ... -
Safe Open-Nested Transactions Through Ownership
(2008-02-20)Researchers in transactional memory (TM) have proposed open nesting asa methodology for increasing the concurrency of a program. The ideais to ignore certain "low-level" memory operations of anopen-nested transaction when ... -
Scalable directoryless shared memory coherence using execution migration
(2010-11-22)We introduce the concept of deadlock-free migration-based coherent shared memory to the NUCA family of architectures. Migration-based architectures move threads among cores to guarantee sequential semantics in large ... -
A Scalable Information Theoretic Approach to Distributed Robot Coordination
(2011-09-25)This paper presents a scalable information theoretic approach to infer the state of an environment by distributively controlling robots equipped with sensors. The robots iteratively estimate the environment state using a ... -
Scalable Information-Sharing Network Management
(2011-06-07)This thesis analyzes scalable information-sharing network management. It looks into one of the large problems in network management today: finding information across different network domains. Information-sharing network ... -
Scalable Internet Routing on Topology-Independent Node Identities
(2003-10-31)Unmanaged Internet Protocol (UIP) is a fully selforganizingnetwork-layer protocol that implements scalableidentity-based routing. In contrast with addressbasedrouting protocols, which depend for scalability oncentralized ... -
Scalar Operand Networks: Design, Implementation, and Analysis
(2004-06-08)The bypass paths and multiported register files in microprocessors serve as an implicit interconnect tocommunicate operand values among pipeline stages and multiple ALUs. Previous superscalar designs implementedthis ... -
Scale Control Processor Test-Chip
(2007-01-12)We are investigating vector-thread architectures which provide competitive performance and efficiency across a broad class of application domains. Vector-thread architectures unify data-level, thread-level, and instruction-level ... -
Scene Classification with a Biologically Inspired Method
(2009-05-10)We present a biologically motivated method for scene image classification. The core of the method is to use shape based image property that is provided by a hierarchical feedforward model of the visual cortex [18]. Edge ...
