We present a new, doubly fast algorithm for Recursive Least-Squares (RLS) adaptive ltering that uses displacement structure and subsampled-updating. The Fast Subsampled-Updating Stabilized Fast Transversal Filter (FSU SFTF) algorithm is mathematically equivalent to the classical Fast Transversal Filter (FTF) algorithm. The FTF algorithm exploits the shift invariance that is present in the RLS a...

An experiment compared dyadic performance in a radio communication and a more sophisticated communication environment to face-to-face (FtF) meetings. Thirty-six dyads, working under low or high time-pressure conditions, needed to combine information and to produce a written plan. Teams working in the sophisticated communication environment collaborated from separate locations over a networked c...

While much research has shown that ALNs can produce learning equivalent to FTF classrooms, there has been little empirical research that explicitly and rigorously explores similarities and differences between the learning processes that occur in ALN and FTF activities. Transcripts from eight case study discussions, 4 FTF, 4 ALN, were content analyzed. The study used a content analytic framework...

OBJECTIVES To compare the clinical and cost-effectiveness of face-to-face (FTF) with over-the-telephone (OTT) delivery of low intensity cognitive behavioural therapy. DESIGN Observational study following SROBE guidelines. Selection effects were controlled using propensity scores. Non-inferiority comparisons assessed effectiveness. SETTING IAPT (improving access to psychological therapies) s...

OBJECTIVE The Family-to-Family Education Program (FTF) is a 12-week course offered by the National Alliance on Mental Illness (NAMI) for family members of adults with mental illness. This study evaluated the course's effectiveness. METHODS A total of 318 consenting participants in five Maryland counties were randomly assigned to take FTF immediately or to wait at least three months for the ne...

Abstract The flame transfer function (FTF) and dynamics of a highly swirled, closely confined, premixed is studied over wide range equivalence ratios bulk velocities at fixed perturbation level the dump plane. operating conditions are varied to examine ratio height velocity in scaling FTF. enclosure geometry kept constant, resulting strong flame-wall interactions for some due varying height. ef...

Dental diseases are among the most prevalent afflictions of humankind. These diseases are associated with the formation of biofilms harboring pathogenic bacteria. Fructosyltransferases (FTF) are extra cellular enzymes of several oral bacteria. FTF are associated with the formation of extracellular polysaccharide matrix (fructans) which play a role in biofilm formation and oral bacteria physiolo...

The ability of Actinomyces naeslundii to convert sucrose to extracellular homopolymers of fructose and to catabolize these types of polymers is suspected to be a virulence trait that contributes to the initiation and progression of dental caries and periodontal diseases. Previously, we reported on the isolation and characterization of the gene, ftf, encoding the fructosyltransferase (FTF) of A....
