The ANTARES telescope neutrino alert system
No full textThe ANTARES telescope has the capability to detect neutrinos produced in astrophysical transient sources. Potential sources include gamma-ray bursts, core collapse supernovae, and flaring active galactic nuclei. To enhance the sensitivity of ANTARES to such sources, a new detection method based on coincident observations of neutrinos and optical signals has been developed. A fast online muon track reconstruction is used to trigger a network of small automatic optical telescopes. Such alerts are generated for special events, such as two or more neutrinos, coincident in time and direction, or single neutrinos of very high energy.This work has been financially supported by the GdR PCHE in France. We want to thank M. Kowalski for discussions on the neutrino triggers and the organization of the optical follow-up.Ageron, M.; Aguilar, J.; Al Samarai, I.; Albert, A.; Andre, M.; Anghinolfi, M.; Anton, G.... (2012).

Svart arbetskraft inom byggbranschen : En studie av små byggföretag
No full textThe construction industry has for several decades demonstrated a problem with financial crime black labour, while the state loses tens of billions of SEK each year due to tax cuts. The government has been fighting undeclared work for several years, and the construction industry is also working to support healthy competition and remove the unequal working conditions that this entails. The purpose of the study is to examine black labour in small companies in the construction industry, the problems that workers are exposed to and why they choose to work in this way. The study was limited to examining small construction companies and the collection of empirical material took place in the Stockholm region. The work is based on previous findings regarding undeclared work as well as semi-structured anonymous interviews conducted with employers and employees working in two small construction companies in the Stockholm region. Both companies make use of illegal workforce and all respondents who lined up admit that they either work illegally full time or alongside their regular jobs. The results show that the undeclared work does not contain any directly bad or unequal working conditions per se which has been the result in some previous studies. The problem is rather that there is no protection if events occur at work and that the state is withheld tax for work done. Furthermore, the study shows that it is a direct desire of the private individuals who are customers to have the work done as undeclared work.

A fast algorithm for muon track reconstruction and its application to the ANTARES neutrino telescope
No full textAn algorithm is presented, that provides a fast and robust reconstruction of neutrino induced upward-going muons and a discrimination of these events from downward-going atmospheric muon background in data collected by the ANTARES neutrino telescope. The algorithm consists of a hit merging and hit selection procedure followed by fitting steps for a track hypothesis and a point-like light source. It is particularly well-suited for real time applications such as online monitoring and fast triggering of optical follow-up observations for multi-messenger studies. The performance of the algorithm is evaluated with Monte Carlo simulations and various distributions are compared with that obtained in ANTARES data.The authors acknowledge the financial support of the funding agencies: Centre National de la Recherche Scientifique (CNRS), Commissariat a l'Energie Atomique et aux Energies Alternatives (CEA), Agence National de la Recherche (ANR), Commission Europenne (FEDER fund and Marie Curie Program), Region Alsace (contrat CPER), Region Provence-Alpes-Cte d'Azur, Departement du Var and Ville de La Seyne-sur-Mer, France; Bundesministerium fur Bildung und Forschung (BMBF), Germany; Istituto Nazionale di Fisica Nucleare (INFN), Italy; Stichting voor Fundamenteel Onderzoek der Materie (FOM), Nederlandse organisatie voor Wetenschappelijk Onderzoek (NWO), the Netherlands; Council of the President of the Russian Federation for young scientists and leading scientific schools supporting grants, Russia; National Authority for Scientific Research (ANCS), Romania; Ministerio de Ciencia e Innovacion (MICINN), Prometeo of Generalitat Valenciana and MultiDark, Spain.
