Cyber security of vehicle CAN bus
2019
There are currently many research projects underway concerning the intelligent transport system (ITS), with the intent to develop a variety of communication solutions between vehicles, roadside stations and services. In the near future, the roll-out of 5G networks will improve short-range vehicle-to-vehicle traffic and vehicle-to-infrastructure communications. More extensive services can be introduced due to almost non-delayed response time. Cyber security is central for the usability of the services and, most importantly, for car safety. The Controller Area Network (CAN) is an automation bus that was originally designed for real-time data transfer of distributed control systems to cars. La…
Cuando el TOC es el producto y la narrativa su mejor representante
2021
Introducción: Según el modelo inferencial para el Trastorno Obsesivo-Compulsivo (TOC), la confusión inferencial da lugar a la narrativa TOC, o discurso interno que el paciente construy a través de la confusión inferencial y cuya función principal es dar credibilidad y fuerza a la duda obsesiva. Por tanto, cuanto más elaborada sea dicha narrativa, más creíble parecerá la obsesión. Las narrativas TOC y las narrativas de las intrusiones (dudas no clínicas) compartirían herramientas de razonamiento generales pero además, las narrativas que subyacen a las obsesiones presentarían unas herramientas de razonamiento específicas del TOC. Los objetivos de este estudio fueron: (1) analizar el nivel de …
¿Mis obsesiones dicen algo sobre quién soy o sobre quién temo ser?
2021
Introducción: Los modelos cognitivo-conductuales para el Trastorno Obsesivo-Compulsivo (TOC) reconocen la relevancia del sí mismo en el TOC, aunque debido a la escasa investigación que existe sobre el tema, la naturaleza específica de esta relación sigue siendo una desconocida. En este estudio nos propusimos: (1) explorar elsí mismo real y el sí mismo temidode un grupo de pacientes con TOC; (2) describir la relación entre ambos tipos de identidad y la intrusión y obsesión más molesta de cada paciente, teniendo en cuenta el contenido de las mismas (autógeno versus reactivo). Método: Un grupo de 58 pacientes con diagnóstico de TOC identificó su obsesión más molesta y una intrusión que había e…
Erosión costera y cambio ambiental en el humeral de Cabanes-Torreblanca (Castelló). Datos para una gestión sostenible
2014
A progressive increase in salinity and marine influence, related to local subsidence characterize the evolution of the lagoon of Cabanes Torreblanca. Relative sea level rise, caused saltwater intrusion and landward migration of the barrier. This barrier is recessive (60-20 m in the last 50 years) and its current processes show a sedimentary deficit that can lead to rapid and irreversible changes. The information shown by this research can help to achieve a sustainable management.
An Approach to Delineate Groundwater Bodies at Risk: Seawater Intrusion in Liepāja (Latvia)
2018
Groundwater quality in coastal areas is frequently affected by seawater intrusion as a consequence of intensive water consumption. To achieve “good chemical status” of a groundwater body according to Water Framework Directive the effects of saline or other intrusions should not be observed. Groundwater pumping in former decades has caused a significant seawater intrusion into confined aquifer in Liepāja and has led to deterioration of relatively wide coastal area of the third largest city in Latvia. However, the area affected by seawater intrusion is a small part of groundwater body F1 which overall chemical status is good. Thus, no specific management measures have been applied to explore …
Strategies for Improving Optimal Positioning of Quality Sensors in Urban Drainage Systems for Non-Conservative Contaminants
2021
In the urban drainage sector, the problem of polluting discharges in sewers may act on the proper functioning of the sewer system, on the wastewater treatment plant reliability and on the receiving water body preservation. Therefore, the implementation of a chemical monitoring network is necessary to promptly detect and contain the event of contamination. Sensor location is usually an optimization exercise that is based on probabilistic or black-box methods and their efficiency is usually dependent on the initial assumption made on possible eligibility of nodes to become a monitoring point. It is a common practice to establish an initial non-informative assumption by considering all network…
Evaluation of a lattice-Boltzmann method for mercury intrusion porosimetry simulations
2004
We have simulated intrusion of a non-wetting liquid into pores of varying shape and size. Simulations were based on the lattice-Boltzmann method and the Shan–Chen multiphase model. The liquid–solid contact angle for pores with circular cross-section was found to be equal to that for pores with square cross-section, and constant even for small pore sizes if the discretised shape of the circular cross-section was taken into account. For comparison, contact angle was also determined for a liquid column descending in a capillary tube, and the results were found to be consistent. Application of the method to mercury intrusion porosimetry is discussed.

UInDeSI4.0 : An efficient Unsupervised Intrusion Detection System for network traffic flow in Industry 4.0 ecosystem
2023
In an Industry 4.0 ecosystem, all the essential components are digitally interconnected, and automation is integrated for higher productivity. However, it invites the risk of increasing cyber-attacks amid the current cyber explosion. The identification and monitoring of these malicious cyber-attacks and intrusions need efficient threat intelligence techniques or intrusion detection systems (IDSs). Reducing the false positive rate in detecting cyber threats is an important step for a safer and reliable environment in any industrial ecosystem. Available approaches for intrusion detection often suffer from high computational costs due to large number of feature instances. Therefore, this paper…
