Code based (“white box”) approach to testing can be divided into two main types: control flow coverage and data flow coverage methods. Dataflow testing was introduced for structural programming languages and later adopted for object languages. Among many tools supporting code based testing of object programs, only JaBUTi and DFC (Data Flow Coverage) support dataflow testing of Java programs. DF...

This paper deals with studying and modeling static friction coefficient (SFC) and dynamic friction coefficient (DFC) of wheat grain as affected by several treatments. Significance of single effect (SE) and dual interaction effect (DIE) of treatments (moisture content and contact surface) on SFC and, SE, DIE, and triple interaction effect (TIE) of treatments (moisture content, contact surface an...

We study direct product representations of algebras in varieties. We collect several conditions expressing that these representations are definable in a first-orderlogic sense, among them the concept of Definable Factor Congruences (DFC). The main results are that DFC is a Mal’cev property and that it is equivalent to all other conditions formulated; in particular we prove that V has DFC if and...

Estimation of functional connectivity (FC) has become an increasingly powerful tool for investigating healthy and abnormal brain function. Static connectivity, in particular, has played a large part in guiding conclusions from the majority of resting-state functional MRI studies. However, accumulating evidence points to the presence of temporal fluctuations in FC, leading to increasing interest...

This paper presents an accumulator-based digital-to-frequency (DFC) converter employing redundant signed binary addition (RSBA). RSBA is advantageous in that no carry propagation occurs resulting in constant delay regardless of operand word size. Utilizing RSBA in the proposed DFC resolves the performance bottleneck in the DFC's conventional implementation and achieves extremely high frequency ...

This document reports an update of DFC. We answer to a question about the rationale for the CP Confusion Permutation. We give new implementation results for DFC. In particular we present an impressively fast implementation which takes 323 cycles on Compaq's 21164 Alpha microprocessor. On the new 21264 we expect to reach software encryption rates over 500 Mbps. We also discuss making DFC scalabl...

PURPOSE To compare the effects of conventional amplification (CA) and digital frequency compression (DFC) amplification on the speech recognition abilities of candidates for a partial-insertion cochlear implant, that is, candidates for combined electric and acoustic stimulation (EAS). METHOD The participants were 6 patients whose audiometric thresholds at 500 Hz and below were <or=60 dB HL an...

The aim of this study was to compare the effect of ferric sulfate (FS) to that of dilute formocresol (DFC) as pulp dressing agents in pulpotomized primary molars. Ninety-six primary molars in 72 children were treated by a conventional pulpotomy technique. Fifty-eight teeth were treated by a FS solution for 15 sec, rinsed, and covered by zinc oxide-eugenol paste (ZOE). In another 38 teeth, a cot...

During the last several years, the focus of research on resting-state functional magnetic resonance imaging (fMRI) has shifted from the analysis of functional connectivity averaged over the duration of scanning sessions to the analysis of changes of functional connectivity within sessions. Although several studies have reported the presence of dynamic functional connectivity (dFC), statistical ...

Several important computer vision tasks have recently been formulated as lowrank problems, with the Low-Rank Representation method (LRR) being one recent and prominent formulation. Although the method is framed as a convex program, available solutions to this program are inherently sequential and costly, thus limiting its scalability. In this work, we explore the effectiveness of a recently int...
