Relentless Computing: Enabling fault-tolerant, numerically intensive computation in distributed environments

by Lucas A. Wilson, John A. Lockman Iii
"... Abstract — This paper suggests a novel computational paradigm for solving numerically intensive problems on a distributed infrastructure. We detail the basic functionality of this new paradigm, its ability to recover from host loss without requiring a complete restart of the code, and how it could a ..."

A C Cross-Compiler for Numerically Intensive Computing on Scalable Parallel Architectures

by Karsten M. Decker, René M. Rehmann , 1991
"... Computational problems in natural science and engineering are characterized by the application of local functions to large and homogeneous data structures. In this paper we give a technical description of a two stage cross-compiler which supports the two major computational models of scientific comp ..."

A computational approach to edge detection

by John Canny - IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE , 1986
"... This paper describes a computational approach to edge detection. The success of the approach depends on the definition of a comprehensive set of goals for the computation of edge points. These goals must be precise enough to delimit the desired behavior of the detector while making minimal assumpti ..."

Computing Inequality: Have Computers Changed the Labor Market?

by David H. Autor, Lawrence F. Katz, Alan B. Krueger - QUARTERLY JOURNAL OF ECONOMICS , 1998
"... This paper examines the effect of skill-biased technological change as measured by computerization on the recent widening of U. S. educational wage differentials. An analysis of aggregate changes in the relative supplies and wages of workers by education from 1940 to 1996 indicates strong and persis ..."

Earthquake Shakes Twitter Users: Real-time Event Detection by Social Sensors

by Takeshi Sakaki, Makoto Okazaki, Yutaka Matsuo - In Proceedings of the Nineteenth International WWW Conference (WWW2010). ACM , 2010
"... Twitter, a popular microblogging service, has received much attention recently. An important characteristic of Twitter is its real-time nature. For example, when an earthquake occurs, people make many Twitter posts (tweets) related to the earthquake, which enables detection of earthquake occurrence ..."
Abstract - Cited by 524 (4 self) - Add to MetaCart
of the numerous earthquakes and the large number of Twitter users throughout the country, we can detect an earthquake by monitoring tweets with high probability (96 % of earthquakes of Japan Meteorological Agency (JMA) seismic intensity scale 3 or more are detected). Our system detects earthquakes promptly

A modular three-dimensional finite-difference ground-water flow model

by Model (michael Mcdonald, Arlen Harbaugh - U.S. Geological Survey Techniques of WaterResources Investigations Book 6, Chapter A1 , 1988
"... The primary objective of this course is to discuss the principals of finite difference methods and their applications in groundwater modeling. The emphasis of the class lectures is on the theoretical aspects of numerical modeling (finite difference method). Steps involved in simulation of groundwate ..."

Low-Power CMOS Digital Design

by Anantha P. Chandrakasan, Samuel Sheng, Robert W. Brodersen - JOURNAL OF SOLID-STATE CIRCUITS. VOL 27, NO 4. APRIL 1992 413 , 1992
"... Motivated by emerging battery-operated applications that demand intensive computation in portable environments, techniques are investigated which reduce power consumption in CMOS digital circuits while maintaining computational throughput. Techniques for low-power operation are shown which use the ..."

Reflectance and texture of real-world surfaces

by Kristin J. Dana, Bram van Ginneken, Shree K. Nayar, Jan J. Koenderink - ACM TRANS. GRAPHICS , 1999
"... In this work, we investigate the visual appearance of real-world surfaces and the dependence of appearance on scale, viewing direction and illumination direction. At ne scale, surface variations cause local intensity variation or image texture. The appearance of this texture depends on both illumina ..."

Edge Detection

by Ellen C. Hildreth , 1985
"... For both biological systems and machines, vision begins with a large and unwieldy array of measurements of the amount of light reflected from surfaces in the environment. The goal of vision is to recover physical properties of objects in the scene, such as the location of object boundaries and the s ..."
Abstract - Cited by 1287 (1 self) - Add to MetaCart
about the physical properties of the scene are provided by the changes of intensity in the image. The importance of intensity changes and edges in early visual processg has led to extensive research on their detection, description and .use, both in computer and biological vision systems.

Multiple sequence alignment with the Clustal series of programs

by Ramu Chenna, Hideaki Sugawara, Tadashi Koike, Rodrigo Lopez, Toby J. Gibson, Desmond G. Higgins, Julie D. Thompson - Nucleic Acids Res , 2003
"... The Clustal series of programs are widely used in molecular biology for the multiple alignment of both nucleic acid and protein sequences and for preparing phylogenetic trees. The popularity of the programs depends on a number of factors, including not only the accuracy of the results, but also the ..."
