The problem of classifying short atrial fibrillatory segments in ambulatory ECG recordings as being either paroxysmal or persistent is addressed by investigating a robust approach to signal characterization. The method comprises preprocessing, estimation of the dominant atrial frequency for the purpose of controlling the subbands of a filter bank, and computation of the relative subband (harmonics
This is the first part of a series of papers devoted to direct and inverse scattering of transient waves in lossy inhomogeneous media. The medium is assumed to be stratified, i.e., it varies only with depth. The wave propagation is modeled in an electromagnetic case with spatially varying permittivity and conductivity. The objective in this first paper is to analyze properties of the scattering op
Two circuits are proposed for double edge-triggered D flip-flops (DETDFFs). A DETDFF responds to both edges of the clock pulse. As compared with positive or negative edge-triggered flip-flops, a DETDFF has advantages in terms of power dissipation and speed. Delay figures for these circuits are measured by simulation. It is shown that these circuits are faster and have lower transistor counts than

A review of a work in Malmö by landscape architect and artist Monika Gora.
This paper describes the development of two test formats, COLLEX and COLLMATCH, measuring receptive recognition knowledge of English verb +NP collocations, and reports findings from pilots and initial test administrations involving Swedish upper-secondaryschool and university level learners. Administrations of the test formats produced highly reliable scores and the performance of native speakers
BACKGROUND: Ghana's maternal mortality ratio remains high despite efforts made to meet Millennium Development Goal 5. A number of studies have been conducted on maternal mortality in Ghana; however, little is known about how the causes of maternal mortality are distributed in different socio-demographic subgroups. Therefore the aim of this study was to assess and analyse the causes of maternal mor
