Eurobalise-Train communication modelling to assess interferences in railway control signalling systems
(Macrothink Institute, 2016-05-10)
The evolution of the railway sector depends, to a great extent, on the deployment of advanced railway signalling systems. These signalling systems are based on communication architectures that must cope with complex ...
Sustainable Cultural Tourism in Urban Destinations: Does Space Matter?
(MDPI, 2016-07)
Policy makers and tourism developers must understand visitors' mobility behavior and how they consume space and tourism resources in order to set up sustainable cultural tourism destinations. With this in mind, it should ...
Aerogels of 1D Coordination Polymers: From a Non-Porous Metal-Organic Crystal Structure to a Highly Porous Material
(MDPI, 2016-01-15)
The processing of an originally non- porous 1D coordination polymer as monolithic gel, xerogel and aerogel is reported as an alternative method to obtain novel metal- organic porous materials, conceptually different to ...
Monetary Diet Cost, Diet Quality, and Parental Socioeconomic Status in Spanish Youth
(Public Library Science, 2016-09-13)
Background
Using a food-based analysis, healthy dietary patterns in adults are more expensive than less healthy ones; studies are needed in youth. Therefore, the objective of the present study was to determine relationships ...
Opposite Cannabis-Cognition Associations in Psychotic Patients Depending on Family History
(Public Library Science, 2016-08-11)
The objective of this study is to investigate cognitive performance in a first-episode psychosis sample, when stratifying the interaction by cannabis use and familial or non-familial psychosis. Hierarchical-regression ...

Review of dynamic line rating systems for wind power integration
(Elsevier, 2016-01)
When a wind power system is connected to a network point there is a limit of power generation based on the characteristics of the network and the loads connected to it. Traditionally, transmission line limits are estimated ...
On the influence of conformity on wheel–rail rolling contact mechanics
(Elsevier, 2016-07)
The aim of this work is to assess the effects of conformity on local contact related quantities at the wheel–rail interface such as traction distributions, subsurface stresses and frictional work distributions.
For this ...
Characterisation of Exposure to Non-Ionising Electromagnetic Fields in the Spanish INMA Birth Cohort: Study Protocol
(Biomed Central, 2016-02-18)
Background: Analysis of the association between exposure to electromagnetic fields of non-ionising radiation (EMF-NIR) and health in children and adolescents is hindered by the limited availability of data, mainly due to ...
An architecture for dynamic QoS management at Layer 2 for DOCSIS access networks using OpenFlow
(Elsevier, 2016-01-15)
Over the last few years, Software-Defined Networking (SDN) has emerged as one of the most disruptive and profitable novelties in networking. SDN was originally conceived to improve performance and reduce costs in Ethernet-based ...
