Mobile health is gradually taking more importance in our society and the need of new power efficient devices acquiring biosignals for long periods of time is becoming substantial. In this thesis, we study the power reduction we could achieve on ECG sensing devices. Emphasis is made on reducing the number of samples both during the sensing phase and the compression phase. To that end, a new sche...

Fuzzy Relational Inference (FRI) systems form an important part of approximate reasoning schemes using fuzzy sets. Especially, the compositional rule of inference (CRI) introduced by Zadeh has attracted the most attention so far. In this work we show that the FRI scheme based on the BandlerKohout subproduct along with a suitable realisation of the fuzzy rules, does possess all the important pro...

BACKGROUND Quantification of renal fluid conservation is possible by urine analysis, and the results can indicate dehydration. The present report sought to determine whether this fluid retention correlates with fluid requirements during major abdominal surgeries that have estimated operating times ≥ 2 h. METHODS Urine colour, specific weight, osmolality and creatinine concentration were used ...

Current means of measuring disease in preclinical models of atherosclerosis include ex vivo assessment of disease tissues post-mortem and non-invasive imaging primarily of structural and anatomic features of lesions, in vivo. A non-invasive, quantitative means of imaging known biologic profiles associated with atherosclerotic disease, in vivo, would enable a robust additional understanding and ...

We address a problem of sampling and reconstructing periodic piecewise polynomials based on the theory for signals with a finite rate of innovation (FRI signals) from samples acquired by a sinc kernel. This problem was discussed in a previous paper. There was, however, an error in a condition about the sinc kernel. Further, even though the signal is represented by parameters, these explicit val...

The MADS domain--containing transcription factor FLOWERING LOCUS C (FLC) acts as an inhibitor of flowering and is a convergence point for several pathways that regulate flowering time in Arabidopsis. In naturally occurring late-flowering ecotypes, the FRIGIDA (FRI) gene acts to increase FLC levels, whereas the autonomous floral promotion pathway and vernalization act to reduce FLC expression. P...

In the winter-annual accessions of Arabidopsis thaliana, presence of an active allele of FRIGIDA (FRI) elevates expression of FLOWERING LOCUS C (FLC), a repressor of flowering, and thus confers a vernalization requirement. FLC activation by FRI involves methylation of Lys 4 of histone H3 (H3K4) at FLC chromatin. Many multicellular organisms that have been examined contain two classes of H3K4 me...

IM-2 [(2R,3R,1'R)-2-1'-hydroxybutyl-3-hydroxymethyl gamma-butanolide] is a gamma-butyrolactone autoregulator which, in Streptomyces lavendulae FRI-5, switches off the production of D-cycloserine but switches on the production of a blue pigment and several nucleoside antibiotics. To clarify the in vivo function of an IM-2-specific receptor (FarA) in the IM-2 signaling cascade of S. lavendulae FR...

This paper introduces a novel detection method for phishing website attacks while avoiding the issues associated with deficiencies of knowledge-based representation and binary decision. The suggested was performed using Fuzzy Rule Interpolation (FRI). FRI reasoning methods added benefit enhancing robustness fuzzy systems effectively reducing system’s complexity. These benefits help Intrusion De...
