... Direct study of magnetic flux penetration and trapping in HTSC. Abstract: . A method for visualization of the magnetic flux penetration and trapping in high-temperature superconductors (HTSC) using magneto-uniaxial ferrimagnetic films is described. The difference in the character of these processes in a number of materials (HTSC single crystals, films and ceramics) is studied. ... Temperature dependences of the local magnetic susceptibility are measured in different sites of the samples. ...

An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . THE PROCESS OF SCIENCE: HOW DO WE KNOW? The nature of the universe, its age, its birth and life story, have been deduced through the process of science. ... In the case of astronomy, it usually starts with making careful observations and measurements -- something your students can begin to do through inspection of astronomical images, and observation of the real sky. ...

Radio Interferometry Principles . Radio Interferometry Signal Processing . ... A radio interferometer consists of a pair of directional antennas that are tuned to receive radio emissions from a source in a desired RF band. ... The antennas are pointed at the radio source of interest and are set up to receive the signal and process it into a form suitable for transmission to the correlator. ... In connected element interferometry, the digital signal goes directly to the correlator. ...

Next: Description of algorithm Up: A Method of Integrating Previous: A Method of Integrating . The fast real-time processing of radiometer signals can be successfully implemented because of the existence of modern high performance ADC and data acquisition systems. ... On the other, hand the median-like rank estimation are very robust to spike type contamination (up to 50%), but there is loss in efficiency in case of normally distributed, spike-free signal. ...

When you enter a command it invokes a program. While this program is running it is called a process . It is important to grasp that although there is only one copy of a program held in the file system , any number of processes can be invoked which run this program. When the operating system is started after a boot , a single process is started. ... Any processes that are started from within your shell - such as entering a command - are the children of this process. ...
