Determination of the Sun's Seismic Radius from SOHO/MDI
Dopplergrams from the Michelson Doppler Imager (MDI) instrument on board the SOHO spacecraft have been used to accurately measure frequencies of the Sun's fundamental (f) mode in the medium angular degree range, l = 88 ? 250. The comparison of these frequencies with the corresponding frequencies of the standard solar models suggests that the apparent photospheric solar radius (695.99 Mm) used t...
متن کاملOn the covering radius of some binary cyclic codes
We compute the covering radius of some families of binary cyclic codes. In particular, we compute the covering radius of cyclic codes with two zeros and minimum distance greater than 3. We compute the covering radius of some binary primitive BCH codes over F2f , where f = 7, 8.
متن کاملSupramolecular NanoStamping (SuNS)
When a useful device is developed, it always requires a mass-production technique to industrialize it. In the era of nano/biotechnology, the development of printing techniques has not followed the speed of the inventions of novel devices. One of the main challenges is handling at the same time the resolution and the chemical complexity of these nano/biodevices. Here a new stamping technique, Su...
متن کاملStudying Changes of the Effective Radius in Blood Vessels after Exposure of Lower Extremities to Periodical Mechanical Vibrations
Background: Previous studies demonstrated a health improving effect in patients underwent an automatic vibratory massage taking 10 minutes. One of reasons that may explain a healing effect of the automatic massage is a stimulated increase in both blood circulation through vascular system and effective size of blood vessels. Objective: This paper aims to quantify a contribution of the auto...
متن کاملMonitoring temporal changes of seismic properties
Temporal changes of seismic properties, such as velocity, attenuation, anisotropy, and scattering properties, have been inferred by active methods for decades and more recently by passive methods. In particular, passive methods are capable of monitoring seismic properties because they do not require earthquakes but rely on continuously excited signals in the ocean, for example, a collection of ...
