Meta Index / Home Page / Description Boolean subexpressions may also be formed from character string constants, identifiers that refer to text columns, and a limited set of associated operators and functions. As in C/C++ a string constant is a list of characters enclosed in double quotes ( " ). ... Examples of valid string constants are: "XMM" , "" , "The double quote: "" , 'A single-quoted string with a double quote (")' . ... upper / lower . ... ascii . ...

Project p2160 is looking at giant pulses from the crab pulsar with high time resolution using a fancy oscilloscope. On previous days an oscillation was seen in the total power output while tracking the source (which includes the nebula). ... While the crab was tracked, a separate total power time series was taken with a 500 Mhz bandwidth centered at 7000 Mhz and a 1 millisecond time constant to check out the oscillations. ... An image was made of the oscillation frequency versus hour angle. ...

... Starting from a grid of theoretical population synthesis models we constructed a set of model galaxies with a distribution of ages, metallicities and intrinsic reddening. ... We propose an optimization technique that combines active learning with an instance-based machine learning algorithm. ... In order to solve the problem more efficiently, we pose it as a learning problem, where a learning algorithm learns the reddening parameters , and with a forward model we compute . ... Let be the test set. ...

The Archeops experiment aimed at measuring the cosmic background emitted just after the Big Bang. The study of this radiation is essential to obtain precise information on the evolution of the Universe: density, Hubble constant, age of the Universe.. To achieve this goal, measurements have been done with devices cooled down at 100mK temperature placed at the focus of a warm telescope. ... 28960 visitors . ...
