Sistema multifunción programable para uso en agricultura.

Número de publicación: 2 338 628 Número de solicitud: 201030144El sistema permite, respecto al resto de programadores de riego del mercado, que se puede utilizar un mismo hardware para realizar multitud de configuraciones diferentes con tan solo cambiar el software, todo ello con un bajo coste. Para ello, incorpora una interfaz software/ hardware consistente en una tarjeta de adquisición de datos DAQ (1) y una placa de adaptación sobre la que se sitúa un convertidor de potencia asociada a las distintas entradas y salidas digitales del sistema, contando con medios de operación manual, paralelos a los medios de operación automáticos constituidos por un software de programación asociado a un ordenador o PC al que se conecta la citada tarjeta de datos, de manera que éste puede integrarse en dicho equipo o constituir un elemento externo y conectado al mismo, indistintamente.Universidad Politécnica de CartagenaUniversidad Miguel Hernández de Elch

Corrosion Propagation Monitoring Using Galvanostatic Pulse on Reinforced Concrete Legacy Samples

This study is aimed to better understand how corrosion propagates on rebars embedded on concrete with supplementary cementitious materials, via legacy samples. Legacy samples were monitored as part of this project. There are indoor and outdoor exposed legacy samples. The outdoor exposed samples were prepared in 1994 with low w/cm and there are both OPC samples and binary mixes (see description in the experimental section). These samples were monitored several times using galvanostatic pulse measurements. The Icorr vs. time during the monitored period are reported in the results section. Several samples either had cracks or developed cracks during the monitored period

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
