Remote built heritage sites face increasingly complex threats from climate, environment, and human activity, challenging traditional preservation methods. The ARGUS EU project introduces a novel, sensor-driven strategy for preventive preservation, tailored to remote and infrastructure-poor heritage contexts. This paper presents the threat-to-sensor mapping framework developed in ARGUS, aligning sensor types with site-specific preservation risks. By combining heterogeneous sensing modalities, low-power communication protocols, and risk-informed design, the system supports actionable early warnings and long-term monitoring. Deployments across five pilot sites address key preservation threats: structural deformation, freeze–thaw cycles, environmental degradation, and biological growth. We describe the sensor selection rationale, installation strategies, and early operational insights across varied heritage contexts.

Model-based systems engineering (MBSE) is a methodology that focuses on creating and exploiting the digital system and engineering domain models as the primary means of exchange of information, feedback, and requirements, as opposed to document-centric systems engineering. The numerical model that encompasses all structural information lies at the heart of the system. Furthermore, this computational model can calculate crucial parameters such as displacements, stresses, and strains. The innovative SEC4TD project, funded by the EIT Raw Materials, proposes an integrated end-to-end (E2E) solution composed of three hardware and software innovative products for mining operators and service providers that will enable multi-scale multi-platform data collection and visualization, events prediction, effective information management, and data traceability. Within this framework, SEC4TD has commenced utilizing the MBSE approach to develop a system specifically for tailings dams. The system integrates all the data from the field, laboratory tests, and monitoring systems to assess the stability of the tailings dam. In the event of unsatisfactory results or the identification of potentially dangerous occurrences, the system immediately notifies the engineering personnel responsible for the tailings storage facility. The MBSE system for tailings dams has been tested at the two tailings storage facilities, one in Poland and another in Bosnia. The article describes the concept, architecture, and data used in the system.

The Internet of Things (IoT) represents a powerful new paradigm for connecting and communicating with the world around us. It has the potential to transform the way we live, work, and interact with our surroundings. IoT devices are transmitting information over the Internet, most of them with different data formats, despite they may be communicating similar concepts. This often leads to data incompatibilities and makes it difficult to extract the knowledge underlying that data. Because of the heterogeneity of IoT devices and data, interoperability is a challenge, and efforts are underway to overcome this through research and standardization. While data collection and monitoring in IoT systems are becoming more prevalent, contextualizing the data and taking appropriate actions to address issues in the monitored environment is still an ongoing concern. Context Awareness is a highly relevant topic in IoT, as it aims to provide a deeper understanding of the data collected and enable more informed decision-making.In this paper, we propose a semantic ontology designed to monitor global entities in the IoT. By leveraging semantic definitions, it enables end-users to model the entire process from detection to action, including context-aware rules for taking appropriate actions. The advantages of using semantic definitions include more accurate and consistent data interpretation, which improves the overall monitoring process and enables more effective decision-making based on the collected insights. Our proposal includes semantic models for defining the entities responsible for monitoring and executing actions, as well as the elements that need to be considered for an effective monitoring process. Additionally, we provide a new definition for the components known as gateways, which enable the connection and communication between devices and the Internet. Finally, we show the benefits of our ontology by applying it to a critical infrastructure domain where a rapid response is vital to prevent accidents and malfunction of the entities.

Developing and maintaining the skills of an increasingly global workforce is a challenge all governments face, particularly as the world emerges from the effects of the2020/21 pandemic. Coupled with the impact of the “Fourth Industrial Revolution” working lives are changing at an unprecedented rate. This article looks at the critical role of transversal skills in enabling ‘employability’, as traditional occupations reconfigure, shift and new roles rapidly appear. Whilst definitions and classifications vary it is agreed that transversal skills are those which an individual can apply across all work roles and life situations, - they are a platform for flexibility, adaptability, and progression. For over 70 years WorldSkills International (WSI) has been working with governments to raise the profile of technical and vocational education (TVET), principally through a biennial global skills competition focusing on excellence. In recent years WSI has been investing in a strong research base working with global partners such as the OECD, ILO and UNESCO. In 2012 it began a project to develop WorldSkills Occupational Standards (WSOS). This article plots the journey WSI has taken to strengthen and embed transversal skills within its standards to ensure the currency of the Competition and more widely drive global skills development forward.

The convergence of operational and information technologies in the industry requires a new generation of IP-compliant communication protocols that can meet the industrial performance requirements while facilitating the integration with novel web-based supervisory control and data acquisition (SCADA) systems. For more than a decade, the industry has relied on time-slotted channel hopping (TSCH) communication technology to meet these performance requirements through standards such as WirelessHART and ISA100.11a. TSCH-based networks have proven to yield over 99.999% end-to-end reliability, supporting flow isolation and QoS management while ensuring over a decade of battery lifetime. However, these technologies were designed to address the factory use cases of a decade ago, not considering IP compliance or standardized network management and resource orchestration as a must. The Internet Engineering Task Force (IETF) and the 6TiSCH working group (WG) have been actively working on this challenge by designing protocols to bridge the performance of industrial solutions with IP-compliant networks. The effort has resulted in 6TiSCH, a set of specifications that define the IPv6 control plane to manage and orchestrate a TSCH network. 6TiSCH provides the missing elements for zero-configuration TSCH network bootstrap, efficient network access authentication, and distributed and modular scheduling mechanisms. As a cross-layer effort, 6TiSCH leverages and integrates other IETF specifications and the WG has also driven the definition of novel specifications in other IETF WGs. An ultimate goal of this effort is the definition of a fully functional architecture where a combination of IETF protocols enables the envisioned convergence on top of the IEEE industrial standard. This paper introduces the work done by the 6TiSCH WG at IETF, evaluates the performance of the reference implementation, and discusses the 6TiSCH software ecosystem.

The single chip integration of a wireless sensor node would allow for cheap, low-power, dust-size devices. The key to realizing this vision is to eliminate bulky off-chip frequency references such as crystal oscillators or resonators, and their associated power-hungry circuitry. The immediate challenge of removing off-chip references is that there is no accurate on-chip frequency references, which makes it hard to tune the radio to the right frequency, and to keep an accurate sense of time. This article offers a full solution for crystal-free devices, which includes (1) initiating communication in an IEEE802.15.4 network, (2) synthesizing the 16 communication channels at startup temperature, and (3) continuously applying corrections to the inaccurate timing source to allow keeping frequency synchronization on all communication channels over a 5-55 • C temperature range. The proposed methods are accompanied by simulations and an experimental validation on the first fully-functional Single Chip Micro Mote hardware implementation. Our simulations and experimental results validate that the proposed approach achieves radio clock synchronization accuracy close to the 40 ppm limit imposed by the IEEE802.15.4 standard.

Cybercriminals use Return Oriented Programming techniques to attack systems and IoT devices. While defenses have been developed, not all of them are applicable to constrained devices. We present Shakedown, which is a compile-time randomizing build tool which creates several versions of the binary, each with a distinct memory layout. An attack developed against one device will not work on another device which has a different memory layout. We tested Shakedown on an industrial IoT device and shown that its normal functionality remained intact while an exploit was blocked.

The manufacturing industry is at the edge of the 4th industrial revolution, a paradigm of integrated architectures in which the entire production chain (composed of machines, workers and products) is intrinsically connected. Wireless technologies can add further value in this manufacturing revolution. However, we identify some signs that indicate that wireless could be left out from the next generation of smart-factory equipment. This is particularly relevant considering that the heavy machinery characteristic of this sector can last for decades. We argue that at the core of this issue there is a mismatch between industrial needs and the interests of academic and partly-academic (such as standardization bodies) sectors. We base our claims on surveys from renowned advisory firms and interviews with industrial actors, which we contrast with results from content analysis of scientific articles. Finally we propose some convergence paths that, while still retaining the degree of novelty required for academic purposes, are more aligned with industrial concerns.
