Abstract. In this paper, we propose efficient algorithms for approximating particular solutions of second and fourth order elliptic equations. The approximation of the particular solution by a truncated series of Chebyshev polynomials and the satisfaction of the differential equation lead to upper triangular block systems, each block being an upper triangular system. These systems can be solved...

The pre-registration house officers (PRHO) is often called upon to interpret electrocardiograms ECG. We invited final-year medical students who had successfully completed their written final examinations, to interpret three rhythm-strip tracings, and three 12-lead ECG tracings. The rhythm-strips were of ventricular fibrillation (VF), ventricular tachycardia (VT), and complete heart block. Of th...

Intra-prediction is amethod for coding standalone frames in video coding. Until now, this hasmainly been done using linear formulae. Using an Artificial Neural Network (ANN)may improve the prediction accuracy, leading to improved coding efficiency. In this degree project, Fully Connected Networks (FCN) and Convolutional Neural Networks (CNN) were used for intra-prediction. Experiments were done...

Self-assembly of amphiphilic block co-polymers composed of poly(ethylene oxide) (PEO) as the hydrophilic block and poly(ether)s, poly(amino acid)s, poly(ester)s and polypropyleneoxide (PPO) as the hydrophobic block can lead to the formation of nanoscopic structures of different morphologies. These structures have been the subject of extensive research in the past decade as artificial mimics of ...

Abstract Background Mobitz type I 2nd degree atrioventricular (AV) block (Wenckebach) is usually considered benign. Guidelines recommend permanent cardiac pacing for patients with II second AV (Mobitz II), but Wenckebach, only indicated if the causes symptoms or conductions delay occurs below bundle of His. However, these guidelines are based on evidence modest quality and a consensus amongst e...

1 of 2 DESCRIPTION A 45-year-old female patient, was admitted with recurrent syncope of 1 month duration. An emergency temporary transvenous right ventricular pacing electrode was placed for complete heart block. The patient developed chest pain and giddiness the following day and electrocardiogram revealed failure to capture and undersensing, with right bundle branch block morphology ( fi gure...

BACKGROUND The addition of a mitral isthmus (MI) block line after pulmonary vein isolation could lead to a favorable outcome of catheter ablation in patients with atrial fibrillation (AF). However, it is sometimes tough to create a complete MI block line, and the cooling effect because of the local coronary flow may prevent the creation of a successful MI block line. METHODS AND RESULTS This ...
