A deep learning approach towards railway safety risk assessment
Railway stations are essential aspects of railway systems, and they play a vital role in public daily life. Various types of AI technology have been utilised in many fields to ensure the safety of people and their assets. In this paper, we propose a novel framework that uses computer vision and pattern recognition to perform risk management in railway systems in which a convolutional neural network (CNN) is applied as a supervised machine learning model to identify risks. However, risk management in railway stations is challenging because stations feature dynamic and complex conditions. Despite extensive efforts by industry associations and researchers to reduce the number of accidents and injuries in this field, such incidents still occur. The proposed model offers a beneficial method for obtaining more accurate motion data, and it detects adverse conditions as soon as possible by capturing fall, slip and trip (FST) events in the stations that represent high-risk outcomes. The framework of the presented method is generalisable to a wide range of locations and to additional types of risks
Automated Level Crossing System: A Computer Vision Based Approach with Raspberry Pi Microcontroller
In a rapidly flourishing country like Bangladesh, accidents in unmanned level
crossings are increasing daily. This study presents a deep learning-based
approach for automating level crossing junctions, ensuring maximum safety.
Here, we develop a fully automated technique using computer vision on a
microcontroller that will reduce and eliminate level-crossing deaths and
accidents. A Raspberry Pi microcontroller detects impending trains using
computer vision on live video, and the intersection is closed until the
incoming train passes unimpeded. Live video activity recognition and object
detection algorithms scan the junction 24/7. Self-regulating microcontrollers
control the entire process. When persistent unauthorized activity is
identified, authorities, such as police and fire brigade, are notified via
automated messages and notifications. The microcontroller evaluates live
rail-track data, and arrival and departure times to anticipate ETAs, train
position, velocity, and track problems to avoid head-on collisions. This
proposed scheme reduces level crossing accidents and fatalities at a lower cost
than current market solutions.

Njord: a fishing trawler dataset
Fish is one of the main sources of food worldwide. The commercial
fishing industry has a lot of different aspects to consider, ranging
from sustainability to reporting. The complexity of the domain also
attracts a lot of research from different fields like marine biology,
fishery sciences, cybernetics, and computer science. In computer science, detection of fishing vessels via for example remote sensing and
classification of fish from images or videos using machine learning
or other analysis methods attracts growing attention. Surprisingly,
little work has been done that considers what is happening on
board the fishing vessels. On the deck of the boats, a lot of data and
important information are generated with potential applications,
such as automatic detection of accidents or automatic reporting of
fish caught. This paper presents Njord, a fishing trawler dataset
consisting of surveillance videos from a modern off-shore fishing
trawler at sea. The main goal of this dataset is to show the potential
and possibilities that analysis of such data can provide. In addition to the data, we provide a baseline analysis and discuss several
possible research questions this dataset could help answer
Enabling technologies and cyber-physical systems for mission-critical scenarios
Programa Oficial de Doutoramento en TecnoloxÃas da Información e Comunicacións en Redes Móbiles . 5029P01[Abstract]
Reliable transport systems, defense, public safety and quality assurance in the Industry 4.0 are essential in a modern society. In a mission-critical scenario, a mission failure would jeopardize human lives and put at risk some other assets whose impairment or loss would significantly harm society or business results. Even small degradations of the communications supporting the mission could have large and possibly dire consequences.
On the one hand, mission-critical organizations wish to utilize the most modern, disruptive and innovative communication systems and technologies, and yet, on the other hand, need to comply with strict requirements, which are very different to those of non critical scenarios. The aim of this thesis is to assess the feasibility of applying emerging technologies like Internet of Things (IoT), Cyber-Physical Systems (CPS) and 4G broadband communications in mission-critical scenarios along three key critical infrastructure sectors: transportation, defense and public safety, and shipbuilding.
Regarding the transport sector, this thesis provides an understanding of the progress of communications technologies used for railways since the implantation of Global System for Mobile communications-Railways (GSM-R). The aim of this work is to envision the potential contribution of Long Term Evolution (LTE) to provide additional features that GSM-R would never support. Furthermore, the ability of Industrial IoT for revolutionizing the railway industry and confront today's challenges is presented. Moreover, a detailed review of the most common flaws found in Radio Frequency IDentification (RFID) based IoT systems is presented, including the latest attacks described in the literature. As a result, a novel methodology for auditing security and reverse engineering RFID communications in transport applications is introduced.
The second sector selected is driven by new operational needs and the challenges that arise from modern military deployments. The strategic advantages of 4G broadband technologies massively deployed in civil scenarios are examined. Furthermore, this thesis analyzes the great potential for applying IoT technologies to revolutionize modern warfare and provide benefits similar to those in industry. It identifies scenarios where defense and public safety could leverage better commercial IoT capabilities to deliver greater survivability to the warfighter or first responders, while reducing costs and increasing operation efficiency and effectiveness.
The last part is devoted to the shipbuilding industry. After defining the novel concept of Shipyard 4.0, how a shipyard pipe workshop works and what are the requirements for building a smart pipe system are described in detail. Furthermore, the foundations for enabling an affordable CPS for Shipyards 4.0 are presented. The CPS proposed consists of a network of beacons that continuously collect information about the location of the pipes. Its design allows shipyards to obtain more information on the pipes and to make better use of it. Moreover, it is indicated how to build a positioning system from scratch in an environment as harsh in terms of communications as a shipyard, showing an example of its architecture and implementation.[Resumen]
En la sociedad moderna, los sistemas de transporte fiables, la defensa, la seguridad pública y el control de la calidad en la Industria 4.0 son esenciales. En un escenario de misión crÃtica, el fracaso de una misión pone en peligro vidas humanas y en riesgo otros activos cuyo deterioro o pérdida perjudicarÃa significativamente a la sociedad o a los resultados de una empresa. Incluso pequeñas degradaciones en las comunicaciones que apoyan la misión podrÃan tener importantes y posiblemente terribles consecuencias.
Por un lado, las organizaciones de misión crÃtica desean utilizar los sistemas y tecnologÃas de comunicación más modernos, disruptivos e innovadores y, sin embargo, deben cumplir requisitos estrictos que son muy diferentes a los relativos a escenarios no crÃticos. El objetivo principal de esta tesis es evaluar la viabilidad de aplicar tecnologÃas emergentes como Internet of Things (IoT), Cyber-Physical Systems (CPS) y comunicaciones de banda ancha 4G en escenarios de misión crÃtica en tres sectores clave de infraestructura crÃtica: transporte, defensa y seguridad pública, y construcción naval.
Respecto al sector del transporte, esta tesis permite comprender el progreso de las tecnologÃas de comunicación en el ámbito ferroviario desde la implantación de Global System for Mobile communications-Railway (GSM-R). El objetivo de este trabajo es analizar la contribución potencial de Long Term Evolution (LTE) para proporcionar caracterÃsticas adicionales que GSM-R nunca podrÃa soportar. Además, se presenta la capacidad de la IoT industrial para revolucionar la industria ferroviaria y afrontar los retos actuales. Asimismo, se estudian con detalle las vulnerabilidades más comunes de los sistemas IoT basados en Radio Frequency IDentification (RFID), incluyendo los últimos ataques descritos en la literatura. Como resultado, se presenta una metodologÃa innovadora para realizar auditorÃas de seguridad e ingenierÃa inversa de las comunicaciones RFID en aplicaciones de transporte.
El segundo sector elegido viene impulsado por las nuevas necesidades operacionales y los desafÃos que surgen de los despliegues militares modernos. Para afrontarlos, se analizan las ventajas estratégicas de las tecnologÃas de banda ancha 4G masivamente desplegadas en escenarios civiles. Asimismo, esta tesis analiza el gran potencial de aplicación de las tecnologÃas IoT para revolucionar la guerra moderna y proporcionar beneficios similares a los alcanzados por la industria. Se identifican escenarios en los que la defensa y la seguridad pública podrÃan aprovechar mejor las capacidades comerciales de IoT para ofrecer una mayor capacidad de supervivencia al combatiente o a los servicios de emergencias, a la vez que reduce los costes y aumenta la eficiencia y efectividad de las operaciones.
