Precomputed Radiance Transfer for Real-Time Rendering in Dynamic, Low-Frequency Lighting Environments
- ACM Transactions on Graphics
, 2002
"... We present a new, real-time method for rendering diffuse and glossy objects in low-frequency lighting environments that captures soft shadows, interreflections, and caustics. As a preprocess, a novel global transport simulator creates functions over the object's surface representing transfer of ..."

GPS-Less Low Cost Outdoor Localization for Very Small Devices.
- IEEE Personal Communications Magazine,
, 2000
"... Abstract-Instrumenting the physical world through large networks of wireless sensor nodes, particularly for applications like environmental monitoring of water and soil, requires that these nodes be very small, light, untethered and unobtrusive. The problem of localization, i.e., determining where ..."

in these networks. In this paper, we review localization techniques and evaluate the effectiveness of a very simple connectivity-metric method for localization in outdoor environments that makes use of the inherent radio-frequency (RF) communications capabilities of these devices.

Sequence Logos: A New Way to Display Consensus Sequences
- Nucleic Acids Res
, 1990
"... INTRODUCTION A logo is "a single piece of type bearing two or more usually separate elements" [1]. In this paper, we use logos to display aligned sets of sequences. Sequence logos concentrate the following information into a single graphic [2]: 1. The general consensus of the sequences. ..."

An initiation point, cut point, or other significant location (if appropriate) . Any aligned set of DNA, RNA or protein sequences can be represented using
ATOMIC DECOMPOSITION BY BASIS PURSUIT
, 1995
"... The Time-Frequency and Time-Scale communities have recently developed a large number of overcomplete waveform dictionaries -- stationary wavelets, wavelet packets, cosine packets, chirplets, and warplets, to name a few. Decomposition into overcomplete systems is not unique, and several methods for d ..."

Basic Block Distribution Analysis to Find Periodic Behavior and Simulation Points in Applications
, 2001
"... Modern architecture research relies heavily on detailed pipeline simulation. Simulating the full execution of an industry standard benchmark can take weeks to months to complete. To overcome this problem researchers choose a very small portion of a program's execution to evaluate their results, ..."

Influence of the number of frequency points and resonance frequencies on model updating techniques for health condition monitoring and damage detection of flexible structures
- Proceedings of the 13-th IMAC
, 1995
"... Structure damage, in general, leads to a variation of the dynamic behaviour of the structures. This variation has been used into a number of existing Non-Destructive Evaluation tools for damage detection. This article shows the influence of the updated parameter choice, number of frequency points an ..."

"... A complete multiple reciprocity method (CMRM), usually employed for the eigenvalue analysis of Helmholtz equation, is applied to impedance calculation of 3D electric structures for multiple frequency points. Based on a recently proposed boundary integral formulations for impedance calculation, the C ..."

Theoretical basis of some empirical relations in seismology
- Bull. Seismol. Soc. Am
, 1975
"... Empirical relations involving seismic moment Mo, magnitude Ms, energy Es and fault dimension L (or area S) are discussed on the basis of an extensive set of earthquake data (M s> = 6) and simple crack and dynamic dislocation models. The relation between log S and log M o is remarkably linear (s ..."

with the dynamic dislocation model for point dis-location rise times and rupture times of most earthquakes. For very large earth-quakes M s ~ (1/3) log M o,, ~ log L ~ (1/3) log E s. For very small earthquakes M s ~ log M o, ~ 3 log L ~ log E s. Scaling rules are assumed and justified. This model predicts log E
Understanding BGP Misconfiguration
- In Proc. ACM SIGCOMM
, 2002
"... It is well-known that simple, accidental BGP configuration errors can disrupt Internet connectivity. Yet little is known about the frequency of misconfiguration or its causes, except for the few spectacular incidents of widespread outages. In this paper, we present the first quantitative study of BG ..."

Intelligent Scissors for Image Composition
- In Computer Graphics, SIGGRAPH Proceedings
, 1995
"... We present a new, interactive tool called Intelligent Scissors which we use for image segmentation and composition. Fully automated segmentation is an unsolved problem, while manual tracing is inaccurate and laboriously unacceptable. However, Intelligent Scissors allow objects within digital images ..."

, rather than simply the strongest edge in the neighborhood. Boundary cooling automatically freezes unchanging segments and automates input of additional seed points. Cooling also allows the user to be much more free with the gesture path, thereby increasing the efficiency and finesse with which boundaries
