Electrical Apparatus-making for Beginners

Electrical safety standards for electrocardiographic apparatus.

IN 1972, the Committee on Electrocardiography of the American Heart Association (AHA) first published recommendations dealing with electrical safety in electrocardiographic (ECG) and vectorcardiographic (VCG) instruments.' These specifications were restated in slightly altered form in 1975.2 To our knowledge, practically all manufacturers of ECG equipment sold in the United States now follow th...

Quantum computing for beginners

The paper introduces the basic concepts and principles behind quantum computing and examines in detail Shor’s quantum algorithm for factoring very large numbers. Some basic methodological principles and guidelines for constructing quantum algorithms are stated. The aim is not to provide a formal exposition of quantum computing but to identify its novelty and potential use in tackling NP-hard pr...
