[Context and motivation] Software Requirement Patterns (SRP) are a type of artifact that may be used during requirements elicitation and that also impact positively in other activities like documentation and validation. In our preliminary experiences at the CITI-CPRHT department, SRP show a great percentage of reuse for the non-functional requirements(More)
Software requirement patterns have been proposed as an artifact for fostering requirements reuse. When we define these patterns for the functional part of a software system, we realize that most of patterns are specific of a software domain. This paper presents and analyzes a catalogue of functional software requirement patterns for the domain of content(More)
The Double Chooz experiment presents an indication of reactor electron antineutrino disappearance consistent with neutrino oscillations. An observed-to-predicted ratio of events of 0.944±0.016(stat)±0.040(syst) was obtained in 101 days of running at the Chooz nuclear power plant in France, with two 4.25 GW(th) reactors. The results were obtained from a(More)
A precise measurement of the proton flux in primary cosmic rays with rigidity (momentum/charge) from 1 GV to 1.8 TV is presented based on 300 million events. Knowledge of the rigidity dependence of the proton flux is important in understanding the origin, acceleration, and propagation of cosmic rays. We present the detailed variation with rigidity of the(More)
A precision measurement by the Alpha Magnetic Spectrometer on the International Space Station of the positron fraction in primary cosmic rays in the energy range from 0.5 to 350 GeV based on 6.8 × 10(6) positron and electron events is presented. The very accurate data show that the positron fraction is steadily increasing from 10 to ∼ 250  GeV, but, from 20(More)
Software Requirement Patterns (SRP) have been proposed as an artifact for fostering requirements reuse. PABRE is a framework that promotes the use of SRP as a means for requirements elicitation, validation and documentation in the context of IT procurement projects. In this paper, we present a catalogue of non-technical SRP included in the framework and(More)
A precision measurement by AMS of the positron fraction in primary cosmic rays in the energy range from 0.5 to 500 GeV based on 10.9 million positron and electron events is presented. This measurement extends the energy range of our previous observation and increases its precision. The new results show, for the first time, that above ∼200  GeV the positron(More)
We report on measurements of hadronic and leptonic cross sections and leptonic forwardbackward asymmetries performed with the L3 detector in the years 1993–95. A total luminosity of 103 pb−1 was collected at centre-of-mass energies √ s ≈ mZ and √s ≈ mZ±1.8 GeV which corresponds to 2.5 million hadronic and 245 thousand leptonic events selected. These data(More)
