An Energy-Efficient MAC Protocol for Wireless Sensor Networks
, 2002
"... This paper proposes S-MAC, a medium-access control (MAC) protocol designed for wireless sensor networks. Wireless sensor networks use battery-operated computing and sensing devices. A network of these devices will collaborate for a common application such as environmental monitoring. We expect senso ..."

Neuronal Synchrony: A Versatile Code for the Definition of Relations?

Image denoising by sparse 3D transform-domain collaborative filtering
- IEEE TRANS. IMAGE PROCESS
, 2007
"... We propose a novel image denoising strategy based on an enhanced sparse representation in transform domain. The enhancement of the sparsity is achieved by grouping similar 2-D image fragments (e.g., blocks) into 3-D data arrays which we call “groups.” Collaborative filtering is a special procedure d ..."

, the collaborative filtering reveals even the finest details shared by grouped blocks and, at the same time, it preserves the essential unique features of each individual block. The filtered blocks are then returned to their original positions. Because these blocks are overlapping, for each pixel, we obtain many
Ratio-Based Decisions and the Quantitative Analysis of cDNA Microarray Images
, 1997
"... Gene expression can be quantitatively analyzed by hybridizing fluor-tagged mRNA to targets on a cDNA microarray. Comparison of gene expression levels arising from cohybridized samples is achieved by taking ratios of average expression levels for individual genes. A novel method of image segmentation ..."

Lossy Compression Of Individual Signals Based On String Matching And One Pass Codebook Design
- In Proceedings ICASSP
"... This paper describes an effort to extend the LempelZiv algorithm to a practical universal lossy compression algorithm. It is based on the idea of approximate string matching with a rate-distortion (R \Gamma D) criterion, and is addressed within the framework of vector quantization (VQ) [4]. A practi ..."

practical one pass algorithm for VQ codebook construction and adaptation for individual signals is developed which assumes no prior knowledge of the source statistics and involves no iteration. We call this technique rate-distortion Lempel-Ziv (RDLZ). As in the case of the Lempel-Ziv algorithm, the encoded
Failure trends in a large disk drive population
- In Proceedings of the 5th USENIX Conference on File and Storage Technologies
, 2007
"... It is estimated that over 90 % of all new information produced in the world is being stored on magnetic media, most of it on hard disk drives. Despite their importance, there is relatively little published work on the failure patterns of disk drives, and the key factors that affect their lifetime. M ..."

. Most available data are either based on extrapolation from accelerated aging experiments or from relatively modest sized field studies. Moreover, larger population studies rarely have the infrastructure in place to collect health signals from components in operation, which is critical information
Successive refinement of information
- Applications
, 1989
"... Abstrocr-The successive refinement of information consists of first approximating data using a few bits of information, then iteratively improving the approximation as more and more information is supplied. The god is to achieve an optimal description at each stage. In general an ongoing description ..."

description is sought which is rate-distortion optimal whenever it is interrupted. It is shown that a rate distortion problem is successively refinable if and only if the individual solutions of the rate distortion problems can be written as a Markov chain. This implies in particular that tree structured
Costly signalling and cooperation
- Journal of Theoretical Biology
, 2001
"... We propose an explanation of cooperation among unrelated members of a social group, in which providing group benefits evolves because it constitutes an honest signal of the member’s quality as a mate, coalition partner or competitor, and therefore results in advantageous alliances for those signalin ..."

Our signaling model is distinctive in applying to group rather than dyadic interactions and in determining endogenously the fraction of the group that signals high
Compulsory averaging of crowded orientation signals in human vision
- Nature Neuroscience
, 2001
"... A shape can be more difficult to identify when other shapes are near it. For example, when several grating patches (see Fig. 1) are viewed parafoveally, observers are unable to report the orientation of the central patch. This phenomenon, known as ‘crowding, ’ has historically been confused with lat ..."

Here we show that despite their inability to report the orientation of an individual patch, observers can reliably estimate the average orientation, demonstrating that the local orientation signals are combined rather
