Fn this paper; two techniques to reduce the energy and the average power consumption oj the system are proposed. They are based on the fact that as lhe tesL pragresses, the detection eficiency of the pseudorundom vectocrs decreases very quickly. Many of Lhe pseudo-random vectors vi11 not detect faults in spile of consuming a signiJicant arnomt of energy(More)
The paper describes the different methods, used in the MAGIC experiment, to unfold experimental energy distributions of cosmic ray particles (g-rays). Questions and problems related to the unfolding are discussed. Various procedures are proposed which can help to make the unfolding robust and reliable. The different methods and procedures are implemented in(More)
We report on the results from the observations in the very high energy band (VHE; GeV) of the black E ≥ 100 g hole X-ray binary (BHXB) Cygnus X-1. The observations were performed with the MAGIC telescope, for a total of 40 hr during 26 nights, spanning the period between 2006 June and November. Searches for steady g-ray signals yielded no positive result,(More)
In this synopsis paper, we present the state of the DBS3 prototype. DBS3 is a parallel relational database system implemented on a shared everything architecture. The design of DBS3 is original for several reasons. First, DBS3 has a compilation approach (compiled C code) which allows a fine grain control of the execution. Second, DBS3 optimizes and(More)
We report the detection of a new source of very high energy (VHE; GeV) g-ray emission located close E ≥ 100 g to the Galactic plane, MAGIC J0616 225, which is spatially coincident with supernova remnant IC 443. The observations were carried out with the MAGIC telescope in the periods 2005 December–2006 January and 2006 December–2007 January. Here we present(More)
M87 is the only known nonblazar radio galaxy to emit very high energy (VHE) gamma rays. During a monitoring program of M87, a rapid flare in VHE gamma-rays was detected by the MAGIC telescope in early 2008. The flux was found to be variable above 350 GeV on a timescale as short as 1 day at a significance level of 5.6 j. The highest measured flux reached 15%(More)
The flat-spectrum radio quasar PKS1441+25 at a redshift of z = 0.940 is detected between 40 and 250 GeV with a significance of 25.5σ using the MAGIC telescopes. Together with the gravitationally lensed blazar QSOB0218 +357 (z = 0.944), PKS1441+25 is the most distant very high energy (VHE) blazar detected to date. The observations were triggered by an(More)
From beginning of to the end of the IRO DB ESPRIT project has developed tools for accessing relational and object oriented databases in an integrated way The sys tem is based on the ODMG standard as pivot model and language It consists of three lay ers The local layer provides for an ODMG in terface to heterogeneous DBMSs the commu nication layer implements(More)
We present a novel automated methodology to detect and classify periodic variable stars in a large data base of photometric time series. The methods are based on multivariate Bayesian statistics and use a multistage approach. We applied our method to the ground-based data of the Trans-Atlantic Exoplanet Survey (TrES) Lyr1 field, which is also observed by(More)
We present the results of stereoscopic observations of the satellite galaxy Segue 1 with the MAGIC Telescopes, carried out between 2011 and 2013. With almost 160 hours of good-quality data, this is the deepest observational campaign on any dwarf galaxy performed so far in the very high energy range of the electromagnetic spectrum. We search this large data(More)
