Complex networks: Structure and dynamics

by S. Boccaletti , V. Latora , Y. Moreno , M. Chavez , D.-U. Hwang , 2006
"... Coupled biological and chemical systems, neural networks, social interacting species, the Internet and the World Wide Web, are only a few examples of systems composed by a large number of highly interconnected dynamical units. The first approach to capture the global properties of such systems is t ..."

Multiscalar Processors

by Gurindar S. Sohi, Scott E. Breach, T. N. Vijaykumar - In Proceedings of the 22nd Annual International Symposium on Computer Architecture , 1995
"... Multiscalar processors use a new, aggressive implementation paradigm for extracting large quantities of instruction level parallelism from ordinary high level language programs. A single program is divided into a collection of tasks by a combination of software and hardware. The tasks are distribute ..."

are dynamically routed among the many parallel pro-cessing units with the help of compiler-generated masks. Memory accesses may occur speculatively without knowledge of preceding loads or stores. Addresses are disambiguated dynamically, many in parallel, and processing waits only for true data dependence

DART: Directed automated random testing

by Patrice Godefroid, Nils Klarlund, Koushik Sen - In Programming Language Design and Implementation (PLDI , 2005
"... We present a new tool, named DART, for automatically testing software that combines three main techniques: (1) automated extraction of the interface of a program with its external environment using static source-code parsing; (2) automatic generation of a test driver for this interface that performs ..."

that performs random testing to simulate the most general environment the program can operate in; and (3) dynamic analysis of how the program behaves under random testing and automatic generation of new test inputs to direct systematically the execution along alternative program paths. Together, these three

Finding structure in time

by Jeffrey L. Elman - COGNITIVE SCIENCE , 1990
"... Time underlies many interesting human behaviors. Thus, the question of how to represent time in connectionist models is very important. One approach is to represent time implicitly by its effects on processing rather than explicitly (as in a spatial representation). The current report develops a pro ..."

proposal along these lines first described by Jordan (1986) which involves the use of recurrent links in order to provide networks with a dynamic memory. In this approach, hidden unit patterns are fed back to themselves; the internal representations which develop thus reflect task demands in the context

Temperature-aware microarchitecture

by Kevin Skadron, Mircea R. Stan, Wei Huang, Sivakumar Velusamy, Karthik Sankaranarayanan, David Tarjan - In Proceedings of the 30th Annual International Symposium on Computer Architecture , 2003
"... With power density and hence cooling costs rising exponentially, processor packaging can no longer be designed for the worst case, and there is an urgent need for runtime processor-level techniques that can regulate operating temperature when the package’s capacity is exceeded. Evaluating such techn ..."

. Validation was performed using finiteelement simulation. The paper also introduces several effective methods for dynamic thermal management (DTM): “temperaturetracking” frequency scaling, localized toggling, and migrating computation to spare hardware units. Modeling temperature at the microarchitecture

Dynamic Units of Visual Speech

by Sarah L. Taylor, Moshe Mahler, Barry-john Theobald, Iain Matthews , 2012
"... We present a new method for generating a dynamic, concatenative, unit of visual speech that can generate realistic visual speech animation. We redefine visemes as temporal units that describe distinctive speech movements of the visual speech articulators. Traditionally visemes have been surmized as ..."

Unsupervised segmentation with dynamical units

by A. Ravishankar Rao, Senior Member, Guillermo A. Cecchi, Charles C. Peck, James R. Kozloski - IEEE Trans Neural Netw , 1999
"... Abstract—In this paper, we present a novel network to separate mixtures of inputs that have been previously learned. A significant capability of the network is that it segments the components of each input object that most contribute to its classification. The network consists of amplitude-phase uni ..."

-phase units that can synchronize their dynamics, so that separation is determined by the amplitude of units in an output layer, and segmentation by phase similarity between input and output layer units. Learning is unsupervised and based on a Hebbian update, and the architecture is very simple. Moreover

Prices and unit labor costs: A new test of price stickiness

by Argia M. Sbordone , 1999
"... This paper investigates the predictions of a simple optimizing model of nominal price rigidity for the aggregate price level and the dynamics of inflation. I compare the model’s predictions with those of a perfectly competitive, flexible price ‘benchmark’ model (corresponding to the model of pricing ..."

DIVA: A Reliable Substrate for Deep Submicron Microarchitecture Design

by Todd M. Austin - In Proc. 32nd Annual Intl. Symp. on Microarchitecture , 1999
"... Building a high-petformance microprocessor presents many reliability challenges. Designers must verify the correctness of large complex systems and construct implementations that work reliably in varied (and occasionally adverse) operating conditions. To&rther complicate this task, deep submicro ..."
Abstract - Cited by 374 (15 self) - Add to MetaCart
submicron fabrication technologies present new reliability challenges in the form of degraded signal quality and logic failures caused by natural radiation interference. In this paper; we introduce dynamic verification, a novel microarchitectural technique that can significantly reduce the burden
