The Central Component of a Triangulation

by Alon Regev , 2013
"... We define the central component of a triangulation of a regular convex polygon as the diameter or triangle containing its geometric center. This definition yields a new recursion relation for Catalan numbers, which can be used to derive congruence relations. We generalize this idea to k-angulations, ..."

Kernel-Based Object Tracking

by Dorin Comaniciu, Visvanathan Ramesh, Peter Meer , 2003
"... A new approach toward target representation and localization, the central component in visual tracking of non-rigid objects, is proposed. The feature histogram based target representations are regularized by spatial masking with an isotropic kernel. The masking induces spatially-smooth similarity fu ..."

Tapestry: An infrastructure for fault-tolerant wide-area location and routing

by Ben Y. Zhao, John Kubiatowicz, Anthony D. Joseph , 2001
"... In today’s chaotic network, data and services are mobile and replicated widely for availability, durability, and locality. Components within this infrastructure interact in rich and complex ways, greatly stressing traditional approaches to name service and routing. This paper explores an alternative ..."

The Cricket Location-Support System

by Nissanka B. Priyantha, Anit Chakraborty, Hari Balakrishnan , 2000
"... This paper presents the design, implementation, and evaluation of Cricket, a location-support system for in-building, mobile, locationdependent applications. It allows applications running on mobile and static nodes to learn their physical location by using listeners that hear and analyze informatio ..."

to advertise this information to; it does not rely on any centralized management or control and there is no explicit coordination between beacons; it provides information to devices regardless of their type of network connectivity; and each Cricket device is made from off-the-shelf components and costs less

Serverless Network File Systems

by Thomas E. Anderson, Michael D. Dahlin, Jeanna M. Neefe, David A. Patterson, Drew S. Roselli, Randolph Y. Wang - ACM TRANSACTIONS ON COMPUTER SYSTEMS , 1995
"... In this paper, we propose a new paradigm for network file system design, serverless network file systems. While traditional network file systems rely on a central server machine, a serverless system utilizes workstations cooperating as peers to provide all file system services. Any machine in the sy ..."

Specifying Distributed Software Architectures

by Jeff Magee, Naranker Dulay, Susan Eisenbach, Jeff Kramer , 1995
"... There is a real need for clear and sound design specifications of distributed systems at the architectural level. This is the level of the design which deals with the high-level organisation of computational elements and the interactions between those elements. The paper presents the Darwin notation ..."
Abstract - Cited by 426 (24 self) - Add to MetaCart
structures and dynamic structures which may evolve during execution. The central abstractions managed by Darwin are components and services. Services are the means by which components interact. In addition to its use in specifying the architecture of a distributed system, Darwin has an operational semantics

Arb: A software environment for sequence data

by Wolfgang Ludwig, Oliver Strunk, Ralf Westram, Lothar Richter, Harald Meier, Arno Buchner, Tina Lai, Wolfram Foè Rster, Igor Brettske, Stefan Gerber, Anton W. Ginhart, Oliver Gross, Silke Grumann, Stefan Hermann, Ralf Jost, Andreas Koè Nig, Thomas Liss, Ralph Luè Ûmann, Michael May, Bjoè Rn Nonhoff, Boris Reichel, Robert Strehlow, Ros Stamatakis, Norbert Stuckmann, Er Vilbig, Michael Lenke, Thomas Ludwig, Arndt Bode - Nucleic Acids Res , 2004
"... The ARB (from Latin arbor, tree) project was initiated almost 10 years ago. The ARB program package comprises a variety of directly interacting software tools for sequence database maintenance and analysis which are controlled by a common graphical user interface. Although it was initially designed ..."

for ribosomal RNA data, it can be used for any nucleic and amino acid sequence data as well. A central database contains processed (aligned) primary structure data. Any additional descriptive data can be stored in database ®elds assigned to the individual sequences or linked via local or worldwide networks. A

The curvelet transform for image denoising

by Jean-Luc Starck, Emmanuel J. Candes, David L. Donoho - IEEE TRANS. IMAGE PROCESS , 2002
"... We describe approximate digital implementations of two new mathematical transforms, namely, the ridgelet transform [2] and the curvelet transform [6], [5]. Our implementations offer exact reconstruction, stability against perturbations, ease of implementation, and low computational complexity. A cen ..."
Abstract - Cited by 404 (40 self) - Add to MetaCart
central tool is Fourier-domain computation of an approximate digital Radon transform. We introduce a very simple interpolation in Fourier space which takes Cartesian samples and yields samples on a rectopolar grid, which is a pseudo-polar sampling set based on a concentric squares geometry.

Human DNA methylomes at base resolution show widespread epigenomic differences.

"... DNA cytosine methylation is a central epigenetic modification that has essential roles in cellular processes including genome regulation, development and disease. Here we present the first genome-wide, single-base-resolution maps of methylated cytosines in a mammalian genome, from both human embryo ..."

Health complaints, stress and distress: exploring the central role of negative affectivity

by David Watson, James W. Pennebaker - Psychological Review , 1989
"... Most current models in health psychology assume that stress adversely affects physical health. We re-examined this assumption by reviewing extensive data from the literature and from six samples of our own, in which we collected measures of personality, health and fitness, stress, and current emotio ..."

emotional functioning. Results indicate that self-report health measures reflect a pervasive mood disposition of negative affectivity (NA); self-report stress scales also contain a substantial NA component. However, although NA is correlated with health complaint scales, it is not strongly or consistently
