High temperature superconductors (HTS) are promising candidates for electrical power applications. The electrical devices using HTS conductors or tapes with high critical temperature (Tc) and high current carrying capability operate with more efficiency and higher power density compared to the conventional one. But the superconductor exhibits energy loss known as AC loss when exposed to time va...

An earthquake detection and recording system known as EARSS has been developed for permanent seismograph stations and temporary field installations. It records three components of ground motion with a dynamic range of 120 dB. A frequency-domain algorithm detects earthquakes and initiates the recording of data on magnetic tape. Alternatively, EARSS can record data continuously, for preselected p...

In order to investigate the influence of mechanical strain on the intrinsic critical current density, a tape conductor is selected as a simple two-dimensional model. In a tape geometry a homogeneous strain distribution can be generated with an external load. A new experimental setup is designed to maintain two different components of the strain tensor (transverse and axial) in a superconducting...

A newly devised instrument is described which permits recording of cardiovascular sound and electrocardiogram during exercise in man. It consists of a handy magnetic casette tape recorder and a modulator. This assembly is connected to a phonocardiographic microphone which is attached to the thorax with sticky tape. The voice of patient is also recordable, if necessary. Biological transducer wil...
