Premature Ventricular Contraction (PVC) is one of the most common cardiac arrhythmias. PVC can occur in healthy people, but for those with frequent occurrence of PVCs, this can often be linked to pathological disorders of the heart. PVC detection allows the physician to diagnose heart disease accurately and also helps cardiac patients to be monitored effectively. This paper presents a novel algorithm...
Holter recording of electrocardiographic signal (ECG) is usually disturbed by noise added to measured useful signal due to e. g. worse contact skin-electrode, body movements, etc. Our general goal is to find at least some piece of information from ECG (in our case - positions of QRS complexes) in corrupted signal, on which common preprocessing methods fail. The main purpose of the article is description...
This paper deals with a scheduling problem with alternative process plans that was motivated by a production of wire harnesses where certain parts can be processed manually or automatically by different types of machines. Only a subset of all the given activities will form the solution, so the decision whether the activity will appear in the schedule has to be made during the scheduling process. The...
Passive optical networks (PONs) represent one of the most attractive access network solutions. TDM and WDM techniques are employed in the PON for higher resource efficiency and capacity, which results in TDM PON and WDM PON respectively. Hybrid WDM-TDM PON combines the advanced features of both TDM PON and WDM PON, and provides a more flexible and cost-effective access network solution. We review...
