Review of Trackside Monitoring Solutions: From Strain Gages to Optical Fibre Sensors.

Abstract: A review of recent research on structural monitoring in railway industry is proposed in this paper, with a special focus on stress-based solutions. After a brief analysis of the mechanical behaviour of ballasted railway tracks, an overview of the most common monitoring techniques is presented. A special attention is paid on strain gages and accelerometers for which the accurate mounting position on the track is requisite. These types of solution are then compared to another modern approach based on the use of optical fibres. Besides, an in-depth discussion is made on the evolution of numerical models that investigate the interaction between railway vehicles and tracks. These models are used to validate experimental devices and to predict the best location(s) of the sensors. It is hoped that this review article will stimulate further research activities in this continuously expanding field.

A dual detector single readout system for simultaneous small (SAXS) and wide-angle X-ray (WAXS) scattering

Abstract: A data acquisition system is described which allows to simultaneously record X-ray scattering patterns in different angular regimes both with high spatial and temporal resolution. It consists of two linear detectors with delay-line readout connected in series. A few examples illustrate its application in the study of the polymorphism of lipid systems and their phase transitions as well as of synthetic polymers.

Comparison of forward hadrons produced in muon interactions on nuclear targets and deuterium

Abstract: Differential multiplicities of forward produced hadrons in deep inelastic muon scattering on nuclear targets have been compared with those from deuterium. The ratios are observed to increase towards unity as the virtual photon energy increases with no significant dependence on the other muon kinematic variables. The hadron transverse momentum distribution is observed to be broadened in nuclear targets. The dependence on the remaining hadron variables is investigated and the results are discussed in the framework of intranuclear interaction models and in the context of the EMC effect.

Measurement of the transverse momentum spectra of weak vector bosons produced in proton-proton collisions at √s=8 TeV

Abstract: The transverse momentum spectra of weak vector bosons are measured in the CMS experiment at the LHC. The measurement uses a sample of proton-proton collisions at sqrt(s) = 8 TeV, collected during a special low-luminosity running that corresponds to an integrated luminosity of 18.4 inverse-picobarns. The production of W bosons is studied in both electron and muon decay modes, while the production of Z bosons is studied using only the dimuon decay channel. The ratios of W- to W+ and Z to W differential cross sections are also measured. The measured differential cross sections and ratios are compared with theoretical predictions up to next-to-next leading order in QCD.
