Single-snapshot file system analysis
- in Proc. of MASCOTS 2013
, 2013
"... Abstract—Metadata snapshots are a common method for gaining insight into filesystems due to their small size and relative ease of acquisition. Since they are static, most researchers have used them for relatively simple analyses such as file size distributions and age of files. We hypothesize that i ..."

into metadata snap-shots, and show a small proof of concept using data from Los Alamos National Laboratories. In our initial work, we see evidence that it is possible to identify user locality information, traditionally the purview of dynamic traces, using a single static snapshot. I.
Single snapshot signal subspace method for target location
- Proc. International URSI/IEEE APS Annual Meeting
, 2005
"... Abstract A signal subspace approach is developed for the passive sensing proW lem of locating radiation-emitting point sources from a single statistical realization or snapshot of the superposed radiation as detected at a receiving antenna array, and for the active sensing problem of locating point ..."

Advances in Radio Science Single snapshot DOA estimation
"... Abstract. In array signal processing, direction of arrival (DOA) estimation has been studied for decades. Many algo-rithms have been proposed and their performance has been studied thoroughly. Yet, most of these works are focused on the asymptotic case of a large number of snapshots. In automotive r ..."

radar applications like driver assistance systems, however, only a small number of snapshots of the radar sen-sor array or, in the worst case, a single snapshot is available for DOA estimation. In this paper, we investigate and compare different DOA estimators with respect to their single snapshot
A framework for modeling positive class expansion with single snapshot
- In PAKDD 2008
"... Abstract. In many real-world data mining tasks, the coverage of the target con-cept may change as the time changes. For example,the coverage of “learned knowledge ” of a student today may be different from his/er “learned knowledge” tomorrow, since the “learned knowledge ” of the student is in expan ..."

High-Resolution Single-Snapshot DOA Estimation in MIMO Radar with Colocated Antennas
"... Abstract—In this paper, a high-resolution subspace-based method is proposed for single-snapshot direction-of-arrival (DOA) estimation in multiple-input multiple-output (MIMO) radar. First, a ‘principal ’ weight vector is designed for transmit beam-forming to achieve a desired transmit power distribu ..."

Capon-Based Single-Snapshot DOA Estimation in Monostatic MIMO Radar
"... We consider the problem of single snapshot direction-of-arrival (DOA) estimation of multiple targets in monos-tatic multiple-input multiple-output (MIMO) radar. When only a single snapshot is used, the sample covariance matrix of the data becomes non-invertible and, therefore, does not permit applic ..."

MUSIC for Single-Snapshot Spectral Estimation: Stability and Super-resolution
, 2014
"... This paper studies the problem of line spectral estimation in the continuum of a bounded interval with one snapshot of array measurement. The single-snapshot measurement data is turned into a Hankel data matrix which admits the Vandermonde decomposition and is suitable for the MUSIC algorithm. The M ..."

Graphs over Time: Densification Laws, Shrinking Diameters and Possible Explanations
, 2005
"... How do real graphs evolve over time? What are “normal” growth patterns in social, technological, and information networks? Many studies have discovered patterns in static graphs, identifying properties in a single snapshot of a large network, or in a very small number of snapshots; these include hea ..."

CC-MUSIC: An Optimization Estimator for Mutual Coupling Correction of L-Shaped Nonuniform Array with Single Snapshot
"... For the case of the single snapshot, the integrated SNR gain could not be obtained without the multiple snapshots, which degrades the mutual coupling correction performance under the lower SNR case. In this paper, a Convex Chain MUSIC (CC-MUSIC) algorithm is proposed for the mutual coupling correct ..."
