Background: Requirements management is considered one of the activities responsible for system failures. The difficulty regarding to requirements trace ability makes the system changes hard to be managed. Objective: This paper presents two approaches that allow the automated generation of the Requirements Trace ability Matrix (RTM): the RTM-E approach, which is based on the requirement input data,...
The Silicon Photomultiplier (SiPM) is a silicon device capable of single photon detection that was developed in the late '90s. It is very promising for High Energy Physics and Medical applications. In order to simplify the operation of such a device for the R&D of small detector prototypes in laboratory and test beams, we developed a versatile readout and control system. It is based on a custom...
A new heavy gauge boson, W′, decaying to a muon and a neutrino, is searched for in pp collisions at a centre-of-mass energy of 7 TeV. The data, collected with the CMS detector at the LHC, correspond to an integrated luminosity of 36 pb−1. No significant excess of events above the standard model expectation is found in the transverse mass distribution of the muon–neutrino system. Masses below 1.40...
A measurement of W+W− production in pp collisions at s=7 TeV and a search for the Higgs boson are reported. The W+W− candidates are selected in events with two leptons, either electrons or muons. The measurement is performed using LHC data recorded with the CMS detector, corresponding to an integrated luminosity of 36 pb−1. The pp → W+W− cross section is measured to be 41.1±15.3(stat)±5.8(syst)±4...
Cardiac allograft vasculopathy (CAV) is the major cause limiting long term graft survival after heart transplantation (HT), and is characterized by changes in coronary artery geometry, such as intimal thickening and vessel remodeling. Given the limited strategies available to reduce its impact on outcome, early diagnosis of CAV - for which intravascular ultrasound (IVUS) is the gold standard - is...
