Host Identification and Location Decoupling a Comparison of ApproachesAntonio Marcos Alberti
The increasing proliferation of mobile devices with Internet access contributed to clarify some important limitations of TCP/IP stack regarding mobility, multihoming, traceability and security. In its original design, Internet IP addresses were overloaded to simultaneously support host identification (ID) and location (Loc). As a consequence, application functionality can be affected when IP addresses are changed to update mobile nodes location. This dual functionality causes many problems in the current Internet, especially in supporting mobility. To deal with this limitations several solutions based on the idea of ID/Loc splitting have been proposed. In this position paper we present and compare some of them, summarizing their main features and limitations. We also identify opportunities and challenges for future research in the area as well as expected impacts/relations with other Future Internet aspects.

Presentation given at ER 2014, 33rd International Conference on Conceptual Modelling, Atlanta, USA, October, 2014
ABSTRACT: Information fragmentation is a well-known issue in personal information management (PIM). In order to overcome this problem, various PIM solutions have focussed on linking documents via semantic relationships. More recently, task-centered information management (TIM) has been introduced as an alternative PIM paradigm. While these two paradigms have their strengths and weaknesses, we aim for a new PIM system design approach to achieve better synergies with human memory. We further envision a cross-media solution where physical information is integrated with a user's digital personal information space. We present the Object-Concept-Context (OC2) conceptual framework for context-aware personal cross-media information management combining the best of the two existing PIM paradigms and integrating the most relevant features of the human memory. Further, we outline how the OC2 framework has been implemented based on a domain-specific application of the Resource-Selector-Link (RSL) hypermedia metamodel.

Paper-Digital User Interfaces - Applications, Frameworks and Future ChallengesBeat Signer
Invited talk given at the User Interface Colloquium, Otto-von-Guericke University Magdeburg, Germany, November 2, 2009
While there have been dramatic increases in the use of digital technologies for information storage, processing and delivery over the last few decades, the affordances of paper have ensured its retention as a key information medium. Despite predictions of the paperless office, paper is ever more present in our daily work. However, there is a gap between the paper and digital worlds: information present in paper documents cannot be seamlessly transferred to digital media and digital services are not easily accessible from the paper world.
ABSTRACT: In this talk I will present an information-centric approach for integrating paper with digital as well as physical media based on a general cross-media information platform (iServer). Some details about the architecture and implementation of the iServer platform as well as the underlying resource-selector-link (RSL) metamodel for cross-media linking will be highlighted. A selection of interactive paper applications that have been developed based on this platform over the past nine years will be presented, including the EdFest interactive paper guide for the Edinburgh festivals, the PaperPoint presentation tool as well as the PaperProof proof-editing solution. Challenges and solutions for novel forms of interactive paper and cross-media publishing are discussed based on the presented applications. This includes specific extensions of the iServer platform and RSL model as well as the application of our solution in new domains such as digital libraries, cross-media annotation and retrieval or personal cross-media information management that goes beyond the hierarchical information management imposed by the desktop metaphor.
Interactive Paper: Past, Present and FutureBeat Signer
Presentation given at PaperComp 2010, 1st International Workshop on Paper Computing, Copenhagen, Denmark, September 2010
ABSTRACT: Over the last few years, there has been a significant increase in the number of researchers dealing with the integration of paper and digital information or services. While recent technological developments enable new forms of paper-digital integration and interaction, some of the original research on interactive paper dates back almost twenty years. We give a brief overview of the most relevant past and current interactive paper developments. Then, based on our experience in developing a wide variety of interactive paper solutions over the last decade, as well as the results of other research groups, we outline future directions and challenges for the realisation of innovative interactive paper solutions.
Further, we propose the definition of common data formats and interactive paper design patterns to ensure future cross-application and framework interoperability.
Cross-Media Information Spaces and Architectures (CISA)Beat Signer
This document describes the research activities of Prof. Beat Signer and the Cross-Media Information Spaces and Architectures (CISA) research group at Vrije Universiteit Brussel. The group is investigating new approaches for managing mixed-media documents in open and fluid cross-media information spaces, including work on data representation, visualization and navigation, and cross-media interaction. Key projects include the RSL hypermedia metamodel, MindXpres content authoring tool, interactive paper applications, personal information management systems, and interfaces that bridge paper and digital media.
The document discusses NoSQL databases and their different classes, including column stores, document stores, and key-value stores. It provides examples of column store databases BigTable and HBase, and notes that document stores like CouchDB allow data to be stored without a predefined schema. The document also discusses object databases and their advantages over relational databases in avoiding the object-relational impedance mismatch.
The document discusses transaction management in databases. It begins with an introduction to transactions, describing them as sequences of operations that form single logical units of work. It then covers the ACID properties that transactions must satisfy: atomicity, consistency, isolation, and durability. The document concludes with descriptions of concurrency control techniques like locking and two-phase locking that allow transactions to execute concurrently while preserving the ACID properties and serializability.
Switching over to Paper: A New Web ChannelBeat Signer
Presentation given at WISE 2003, 4th International Conference on Web Information Systems Engineering, Rome, Italy, December 2003
ABSTRACT: We present a general web-based information infrastructure capable of supporting the rapid development of highlyinteractive information environments that cater for widely varying requirements across application domains and all forms of fixed and mobile client devices. In particular, we describe how this infrastructure has been extended to support digitally augmented paper through a special transformation component that can map active areas of document pages to information objects so that user- and contextdependent interaction can be supported. Our infrastructure is sufficiently general and flexible to adapt to, not only emerging and even unanticipated technologies in the area of interactive paper, but also the rapidly expanding interaction sphere of hypermedia.
The document discusses how networks and applications can become more aware of each other to improve the experience for end users. Currently, networks and applications operate independently without much visibility into each other. The document proposes that applications share information about end users and traffic with networks, and networks share information about topology, bandwidth, and resources with applications. This would allow applications to optimize content placement and resource usage, and networks to gain insights to better optimize traffic and provide new services. The document argues this type of programmable network can improve areas like security, performance, analytics and more.

Personalised Learning Environments Based on Knowledge Graphs and the Zone of ...Beat Signer
Presentation given at CSEDU 2022, Virtual Event.
The learning of new knowledge and skills often requires previous knowledge, which can lead to some frustration if a teacher does not know a learner's exact knowledge and skills and therefore confronts them with exercises that are too difficult to solve. We present a solution to address this issue when teaching techniques and skills in the domain of table tennis, based on the concrete needs of trainers that we have investigated in a survey. We present a conceptual model for the representation of knowledge graphs as well as the level at which individual players already master parts of this knowledge graph. Our fine-grained model enables the automatic suggestion of optimal exercises in a player's so-called zone of proximal development, and our domain-specific application allows table tennis trainers to schedule their training sessions and exercises based on this rich information. In an initial evaluation of the resulting solution for personalised learning environments, we received positive and promising feedback from trainers. We are currently investigating how our approach and conceptual model can be generalised to some more traditional educational settings and how the personalised learning environment might be further improved based on the expressive concepts of the presented model.

Codeschool in a Box: A Low-Barrier Approach to Packaging Programming CurriculaBeat Signer
Presentation given at CSEDU 2023, Prague, Czech Republic.
The tech industry is a fast-growing field, with many companies facing issues in finding skilled workers to fill their open vacancies. At the same time, many people have limited access to the quality education necessary to enter this job market. To address this issue, various small and often volunteer-run non-profit organisations have emerged to up-skill capable learners. However, these organisations face tight constraints and many challenges while trying to design and deliver high-quality education to their learners. In this position paper, we discuss some of these challenges and present a preliminary version of a curriculum packager addressing some of these issues. Our proposed solution, inspired by first-hand experience in these organisations as well as computing education research (CER), is based on a combination of micromaterials, study lenses and a companion mobile application. While our solution is designed for the specific context of small organisations providing vocational ICT training, it can also be applied to the broader domain of learning environments facing similar constraints.

Towards a Framework for Dynamic Data PhysicalisationBeat Signer
This document proposes a framework for dynamically physicalizing data. It describes the Tangible Hologram (TangHo) platform, which uses a 6 degree of freedom robotic arm prototype built from Lego Mindstorms. The arm can interact bidirectionally with a user through holograms displayed via HoloLens. Challenges include inverse kinematics since the final system will be body mounted.

In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
