Cyber Security of Critical Infrastructures

Critical infrastructures are vital assets for public safety, economic welfare, and the national security of countries. The vulnerabilities of critical infrastructures have increased with the widespread use of information technologies. As Critical National Infrastructures are becoming more vulnerable to cyber-attacks, their protection becomes a significant issue for organizations as well as nations. The risks to continued operations, from failing to upgrade aging infrastructure or not meeting mandated regulatory regimes, are considered highly significant, given the demonstrable impact of such circumstances. Due to the rapid increase of sophisticated cyber threats targeting critical infrastructures with significant destructive effects, the cybersecurity of critical infrastructures has become an agenda item for academics, practitioners, and policy makers. A holistic view which covers technical, policy, human, and behavioural aspects is essential to handle cyber security of critical infrastructures effectively. Moreover, the ability to attribute crimes to criminals is a vital element of avoiding impunity in cyberspace. In this book, both research and practical aspects of cyber security considerations in critical infrastructures are presented. Aligned with the interdisciplinary nature of cyber security, authors from academia, government, and industry have contributed 13 chapters. The issues that are discussed and analysed include cybersecurity training, maturity assessment frameworks, malware analysis techniques, ransomware attacks, security solutions for industrial control systems, and privacy preservation methods

Data Technology in Materials Modelling

This open access book discusses advances in semantic interoperability for materials modelling, aiming at integrating data obtained from different methods and sources into common frameworks, and facilitating the development of platforms where simulation services in computational molecular engineering can be provided as well as coupled and linked to each other in a standardized and reliable way. The Virtual Materials Marketplace (VIMMP), which is open to all service providers and clients, provides a framework for offering and accessing such services, assisting the uptake of novel modelling and simulation approaches by SMEs, consultants, and industrial R&D end users. Semantic assets presented include the EngMeta metadata schema for research data infrastructures in simulation-based engineering and the collection of ontologies from VIMMP, including the ontology for simulation, modelling, and optimization (OSMO) and the VIMMP software ontology (VISO)

The Big Five:Addressing Recurrent Multimodal Learning Data Challenges

The analysis of multimodal data in learning is a growing field of research, which has led to the development of different analytics solutions. However, there is no standardised approach to handle multimodal data. In this paper, we describe and outline a solution for five recurrent challenges in the analysis of multimodal data: the data collection, storing, annotation, processing and exploitation. For each of these challenges, we envision possible solutions. The prototypes for some of the proposed solutions will be discussed during the Multimodal Challenge of the fourth Learning Analytics & Knowledge Hackathon, a two-day hands-on workshop in which the authors will open up the prototypes for trials, validation and feedback

Multimodal Challenge: Analytics Beyond User-computer Interaction Data

This contribution describes one the challenges explored in the Fourth LAK Hackathon. This challenge aims at shifting the focus from learning situations which can be easily traced through user-computer interactions data and concentrate more on user-world interactions events, typical of co-located and practice-based learning experiences. This mission, pursued by the multimodal learning analytics (MMLA) community, seeks to bridge the gap between digital and physical learning spaces. The “multimodal” approach consists in combining learners’ motoric actions with physiological responses and data about the learning contexts. These data can be collected through multiple wearable sensors and Internet of Things (IoT) devices. This Hackathon table will confront with three main challenges arising from the analysis and valorisation of multimodal datasets: 1) the data collection and storing, 2) the data annotation, 3) the data processing and exploitation. Some research questions which will be considered in this Hackathon challenge are the following: how to process the raw sensor data streams and extract relevant features? which data mining and machine learning techniques can be applied? how can we compare two action recordings? How to combine sensor data with Experience API (xAPI)? what are meaningful visualisations for these data

Collaborative Game-based Learning - Automatized Adaptation Mechanics for Game-based Collaborative Learning using Game Mastering Concepts

Learning and playing represent two core aspects of the information and communication society nowadays. Both issues are subsumed in Digital Education Games, one major field of Serious Games. Serious Games combine concepts of gaming with a broad range of application fields: among others, educational sectors and training or health and sports, but also marketing, advertisement, political education, and other societally relevant areas such as climate, energy, and safety. This work focuses on collaborative learning games, which are Digital Educational Games that combine concepts from collaborative learning with game concepts and technology. Although Digital Educational Games represent a promising addition to existing learning and teaching methods, there are different challenges opposing their application. The tension between a game that is supposed to be fun and the facilitation of serious content constitutes a central challenge to game design. The often high technical complexity and especially the instructors' lack of control over the game represent further challenges. Beyond that, the distinct heterogeneity of learners who often have different play styles, states of knowledge, learning speed, and soft skills, such as teamwork or communication skills, forms a pivotal problem. Apart from that, the vital role of the instructor needs to be taken into account. Within the scope of this dissertation, the problems mentioned above are analyzed, concepts to solve them introduced, and methods developed to address them. The first major contribution contains the conceptualization of a framework for adaptation of collaborative multiplayer games as well as for the control of those games at run-time through an instructor using the Game Master principle. The core concept hereby addresses the design of a model to represent heterogeneous groups and to represent collaborative Serious Games. Based on that, a novel concept for adaptation of collaborative multiplayer games is developed, implemented, and evaluated. Automatic recognition and interpretation of game situations, as well as determination of the most well suited adaptation based on the recognized situations, is a major challenge here. Further, a concept is developed to integrate an instructor in a meaningful way into the course of the game, giving him/her the necessary resources to recognize problems and to intervene and adapt the game at run-time. Therefore, it will be taken into account that the elaborated concepts are applicable in a generic way independent of the underlying game. The second major contribution of this work is the conceptualization and design of a simulation of players and learners in a collaborative multiplayer game that behave realistically based on a player, learner, and interaction model. This is supposed to enable an evaluation of the adaptation and Game Mastering concepts using freely configurable player and learner types. The concepts introduced and developed within this thesis have been thoroughly evaluated using a twofold approach. As a test environment, a collaborative multiplayer Serious Game was designed and implemented. Within that simulation environment, the developed Game Mastering and adaptation concepts were assessed and tested with large sets of virtual learners. Additionally, the concepts were evaluated with real users. Therefore, two different evaluation studies with a total of 60 participants were conducted. The results of the conducted evaluations help to broaden the areas of application of Serious Games as well as to improve their applicability, hence raising acceptance among instructors. The models, architectures, and software solutions developed within this thesis thus build a foundation for further research of multiplayer Serious Games

End-userApplication for Early Forest Fire Detection and Prevention

n this paper, we describe a Web application that has been designed and implemented by Fulda University of Applied Sciences in the context of the ASPires project. The application extends the functionality available to Crisis Management Centers (CMC). Actual readings from sensors installed in the test areas, for example national parks, are made available to CMC personnel, as well as pictures from cameras that are either mounted on stationary observation towers or taken by Unmanned Aerial Vehicles (UAVs) in the area of an actual of supposed forest fire. Data are transmitted to the Aspires cloud and delivered swiftly to the Web application via an open interface. Furthermore, fire alarms raised by novel detection algorithms are forwarded automatically to the application. This clearly improves the potential for the early detection of forest fires in rural areas

We first present the advanced design and structural model of an advanced system for monitoring of forest area. This model integrate sensor networks and mobile (drone) technologies for data collection and acquisition of those data at existing Crisis Management Information Systems (CMIS). Then we demonstrate the possibility to map different technological solutions and the main result was the definition of the set of standard interfaces and protocols for network interoperability

Premodern Experience of the Natural World in Translation

This innovative collection showcases the importance of the relationship between translation and experience in premodern science, bringing together an interdisciplinary group of scholars to offer a nuanced understanding of knowledge transfer across premodern time and space. The volume considers experience as a tool and object of science in the premodern world, using this idea as a jumping-off point from which to view translation as a process of interaction between diff erent epistemic domains. The book is structured around four dimensions of translation—between terms within and across languages; across sciences and scientific norms; between verbal and visual systems; and through the expertise of practitioners and translators—which raise key questions on what constituted experience of the natural world in the premodern area and the impact of translation processes and agents in shaping experience. Providing a wide-ranging global account of historical studies on the travel and translation of experience in the premodern world, this book will be of interest to scholars in history, the history of translation, and the history and philosophy of science
