Approximation Algorithms for Connected Dominating Sets
 Algorithmica
, 1996
"... The dominating set problem in graphs asks for a minimum size subset of vertices with the following property: each vertex is required to either be in the dominating set, or adjacent to some node in the dominating set. We focus on the question of finding a connected dominating set of minimum size, whe ..."

, where the graph induced by vertices in the dominating set is required to be connected as well. This problem arises in network testing, as well as in wireless communication. Two polynomial time algorithms that achieve approximation factors of O(H (\Delta)) are presented, where \Delta is the maximum
Odds ratio, delta, ETS classification, and standardization measures of DIF magnitude for binary logistic regression
 Journal of Educational and Behavioral Statistics
, 2007
"... Previous methodological and applied studies that used binary logistic regression (LR) for detection of differential item functioning (DIF) in dichotomously scored items either did not report an effect size or did not employ several useful measures of DIF magnitude derived from the LR model. Equatio ..."

. Equations are provided for these effect size indices. Using two large data sets, the authors demonstrate the usefulness of these effect sizes for judging practical importance: the LR adjusted odds ratio and its conversions to the delta metric, the Educational Testing Service (ETS) classification system

Delta Algorithms: An Empirical Analysis
, 1998
"... Delta algorithms compress data by encoding one file in terms of another. This type of compression is useful in a number of situations: storing multiple versions of data, displaying differences, merging changes, distributing updates, storing backups, transmitting video sequences, and others. This pap ..."

DELTASIGMA MODULATORS WITH LOW OVERSAMPLING RATIOS
"... This dissertation explores methods of reducing the oversampling ratio (OSR) of both deltasigma (∆Σ) modulators and incremental data converters. The first reducedOSR architecture is the highorder cascaded ∆Σ modulator. These ∆Σ modulators are shown to reduce the inband noise sufficiently at OSRs ..."

The modern compressors also correlate better with the actual difference between files; one of them is even faster than diff in both compression and decompression speed. 1 Introduction Delta algorithms, i.e., algorithms that compute differences between two files or strings, have a number of uses
Metropolized Independent Sampling with Comparisons to Rejection Sampling and Importance Sampling
, 1996

Online Interval Scheduling
 In Proceedings of the Fifth Annual ACMSIAM Symposium on Discrete Algorithms
, 1994
"... We introduce the online interval scheduling problem, in which a set of intervals of the positive real line is presented to a scheduling algorithm in order of start time. Upon seeing each interval, the algorithm must decide whether or not to "schedule " it. Overlapping intervals may not be ..."

For the general case in which intervals may have arbitrary lengths, \Delta, the ratio of longest to shortest interval, is the important parameter. We
