A Contextual Approach to Privacy Online
Authors: Nissenbaum Helen
Published: February 2025

Recent media revelations have demonstrated the extent of third-party tracking and monitoring online, much of it spurred by data aggregation, profiling, and selective targeting. How to protect privacy online is a frequent question in public discourse and has reignited the interest of government actors. In the United States, notice-and-consent remains the fallback approach in online privacy policies, despite its weaknesses. This essay presents an alternative approach, rooted in the theory of contextual integrity. Proposals to improve and fortify notice-and-consent, such as clearer privacy policies and fairer information practices, will not overcome a fundamental flaw in the model, namely its assumption that individuals can understand all facts relevant to true choice at the moment of pair-wise contracting between individuals and data gatherers. Instead, we must articulate a backdrop of context-specific substantive norms that constrain what information websites can collect, with whom they can share it, and under what conditions it can be shared. In developing this approach, the paper warns that the current bias in conceiving of the Net as a predominantly commercial enterprise seriously limits the privacy agenda.
Shear-Capacity in Adhesive Glass Joints
Authors: Fröling Maria  , Persson Kent  , Larsson Oskar
Published: February 2025

The shear-capacity of adhesive glass-joints was investigated. Various stiff and soft adhesives were tested in a short-term load-case. The tests were conducted with small specimens in order to achieve a homogenous state of stress. The results of the tests were used in order to determine the material models of the adhesives. Finite element analysis of the test set-up was used for the determination of the material models. Large-scale tests were conducted to verify the material models from the tests of the small specimens. It could be concluded that with further validation, a combination of small-specimen tests and finite element simulations may allow for the determination of joint behavior for any joint size.

Authors: Rodichev Yurii  , Yevplov Yurii  , Soroka Helen  , Veer Frederic  , Tregubov Nikolay  , Polivyany Vladimir
Published: February 2025

Statistical distribution of the data on the bending strength of float glass systematically deviates from the Weibull statistic distribution [1–3]. It was shown that surface defects formed under glass processing and handing are the cause of the multi linear nature of the Weibull plots. The results of an experimental study of statistical distribution of bending strength values were obtained in view of the effect of mechanical treatment and contact loads on glass surface damaging and strength. The shapes and sizes of fracture sources – critical micro-cracks and damages were investigated. It was shown that the statistical behavior of structural glass strength may be controlled by monitoring critical surface defects, conditions of their formation in production of load carrying glass structures basing on experimental strength data.

Authors: Serafinavičius Tomas  , Šaučiuvėnas Gintas  , Hildebrand Jörg
Published: February 2025

This paper deals with the results received by carried out tensile tests of the structural glass plates supplied with three different types of stress raisors. The first type of specimens is the plate with a circular hole located in the centre of the plate, the second one is the plate with a slot hole located in the centre of the plate, and the third one is the plate with the semicircular notches located at the opposite edges. The results of test of these specimens were compared both among themselves and both with the results of the specimens without stress raisors. The specimens were made from tempered glass of 6 mm thick with the arrising edges. All tests were carried out under equal conditions; the load level has been raised within each 1.0 kN. The experiment was performed with an optical device for measurement of the stresses by birefringence. Detailed analysis of the obtained results is given in this paper.

Reinforced Glass Beams Composed of Annealed, Heat-Strengthened and Fully Tempered Glass
Authors: Louter Christian  , Belis Jan  , Bos Freek  , Veer Fred
Published: February 2025

Annealed, heat-strengthened and fully tempered SG-laminated reinforced glass beam specimens were subjected to four-point bending tests to investigate the effects of glass type on their structural response. During the test the beams showed linear elastic response until initial glass failure, followed by a significant post-breakage strength and ductility. From the results it was concluded that the application of stronger glass types in reinforced glass beams significantly enhances their initial glass breakage strength, but affects their post-breakage strength and ductility in a negative way. The annealed and heat-strengthened beams reached similar post-breakage strength levels, whereas this was reduced for the fully tempered beams. Furthermore, compared to the annealed beams the post-breakage ductility was reduced for the heat-strengthened and even further reduced for the fully tempered beams. These differences originated from differences in fragmentation of the glass.
Lincoln Center Canopies – Performance in Glass
Authors: Knippers Jan  , Riederer Jochen  , Oppe Matthias
Published: February 2025

This paper concerns two cantilevering steel-glass structures recently built in New York, USA. Each structure consists of two outward tilting primary steel beams with a length of 27m, a central column, and a glass surface providing lateral stability and weather protection. Twelve panels of four-layer laminated safety glass with dimensions of 2,3×4,4m are connected to the underside of the beams. The glass panels act as the only bracing system of the structure; no additional bracing is required. The connection between glass and steel is made by custom-built point fittings with four fittings per glass panel connected by a two-part injection mortar. At the column kink a ‘glass knee’ of two frameless four-layer laminated safety glass panels is used for even load distribution.
Layout Strategies and Optimisation of Joint Patterns in Full Glass Shells
Authors: Fildhuth Thiemo  , Lippert Sebastian  , Knippers Jan
Published: February 2025

Continuously curved, full glass shells have a large potential for application in free-form façades or roofs. Glass elements needed for such a construction can be fabricated either by heat bending or cold lamination bending. But as the curvature and size of glass laminates are limited by manufacturing restrictions, structural joining is necessary for assembling large shells. Unfortunately, such joint discontinuities conflict with the desired membrane state of the shell. The joint pattern layout has a large influence on the load bearing behaviour, stability and appearance of glass shells. Hence, computational procedures have been used to optimise the joint geometry layout by targeting either at minimising particular joint forces or by following the principal membrane force trajectories of the shell.

DELICAT – Demonstration of Lidar Based Clear Air Turbulence Detection
Authors: Barny Hervé
Published: February 2025

Atmospheric turbulence encounters are the leading cause of injuries to passengers and flight crews in non-fatal accidents. A whole class of turbulences, representing 40% of turbulence accidents and designated as Clear Air Turbulence (CAT), cannot be detected by any existing airborne equipment, even modern weather radars. The objective of the European project “DELICAT” – Demonstration of Llidar-based Air Turbulence – is to test an airborne Lidar developed to detect Clear Air Turbulence (CAT) ahead of an aircraft, thus allowing an anticipated reaction to mitigate the CAT effect.

Archives Information Publishing New Design in Post-Custodial Regime: the National Archives Experience Digital Vaults
Authors: Jorente Maria José Vicentini
Published: February 2025

The uses of Information and Communication Technologies (ICT) and Web environments for creation, treatment and availability of information have supported the emergence of new social-cultural patterns represented by convergences in textual, image and audio languages. This paper describes and analyzes the National Archives Experience Digital Vaults as a digital publishing web environment and as a cultural heritage. It is a complex system – synthesizer of information design options at information setting, provides new aesthetic aspects, but specially enlarges the cognition of the subjects who interact with the environment. It also enlarges the institutional spaces that guard the collective memory beyond its role of keeping the physical patrimony collected there. Digital Vaults lies as a mix of guide and interactive catalogue to be dealt in a ludic way. The publishing design of the information held on the Archives is meant to facilitate access to knowledge. The documents are organized in a dynamic and not chronological way. They are not divided in fonds or distinct categories, but in controlled interaction of documents previously indexed and linked by the software. The software creates information design and view of documental content that can be considered a new paradigm in Information Science and are part of post-custodial regime, independent from physical spaces and institutions. Information professionals must be prepared to understand and work with the paradigmatic changes described and represented by the new hybrid digital environments; hence the importance of this paper. Cyberspace interactivity between user and the content provided by the environment design provide cooperation, collaboration and sharing knowledge actions, all features of networks, transforming culture globally.
Social Network Analysis of Learning Teams During Emergency Events
Authors: Hamra Jafar  , Hossain Liaquat  , Owen Christine
Published: February 2025

Understanding factors that enhance or diminish learning and adaptability levels of individuals is instrumental in achieving individual and organizational performance goals. In this study, the effect of social network structure on learning attitudes of emergency personnel during an emergency event is investigated. Based on social network theories, and the social influence model of learning, a theoretical framework is proposed to investigate the effects of network structure on learning outcome of bushfire coordinating teams. To test our framework, we investigate social network data which has been extracted from the transcripts of the 2009 Victorian Bushfires Royal Commission report. Empirical results suggest that network structure of emergency personnel play a crucial role in the ability of those actors to engage in learning-related work activity. We infer that this will mean that these actors are better able to adapt and improvise in complex emergency events. We suggest that social network analysis may have a valuable part to play in the study of emergency events. By presenting a model of learning-related work activity, based on network structure, personnel within emergency services organizations can strengthen their capacity to be flexible and adaptable.

Authors: Susnjak Teo  , Barczak Andre  , Reyes Napoleon  , Hawick Ken
Published: February 2025

We propose a general method applicable to existing multiclass boosting-algorithms for creating cascaded classifiers. The motivation is to introduce more tractability to machine learning tasks which require large datasets and involve complex decision boundaries, by way of separate-and-conquer strategies that reduce both the training and detection-phase overheads. The preliminary study explored the application of our method to AdaBoost.ECC on six UCI datasets and found that a decrease in the computational training and evaluation overheads occurred without significant effects on the generalization of the classifiers.

Published: February 2025

Our main contribution is a surprising polynomial-time algorithm for weighed coalitional manipulation of four-candidate Copeland (also known as Llull) elections. On the technical side, our algorithm relies on a polynomial-time routine that solves a variant of the partition problem. We also show that there is a pseudopolynomial-time algorithm for weighted coalitional manipulation with a fixed number of candidates under any anonymous rule with a polynomial-time winner-determination procedure.
Conservative Social Laws
Authors: Ågotnes Thomas  , van der Hoek Wiebe  , Wooldridge Michael
Published: February 2025

Social laws – sets of constraints imposed on the behaviour of agents within a multi-agent system with the goal of some desirable overall behaviour resulting – are an important mechanism for coordinating multi-agent behaviour. When considering social laws in human environments, the inspiration for social laws in multiagent systems, we argue that a key design principle is least change. That is, social laws are more likely to be accepted and adopted, and hence successful, if they are conservative, in the sense that they represent the smallest change possible from the pre-existing status quo that is required to effect the desired objective. Our aim in the present paper is to introduce, formalise, and investigate the notion of a conservative social law for multi-agent systems. To make the idea of a conservative social law precise, we formalise the notion of a distance metric for social laws, and discuss a range of possible properties for such metrics. We then formulate the conservative social law problem, (i.e., the problem of constructing an effective social law that requires the least change according to this metric), discuss some possible interpretations of distance in this context, and discuss some issues surrounding conservative social laws.
Nearness Rules and Scaled Proximity
Authors: LÖzçep Özgür L.  , Grütter Rolf  , Möller Ralf
Published: February 2025

An artificial intelligence system that processes geothematic data would profit from a (semi-)formal or controlled natural language interface that incorporates concepts for nearness. Though there already exists logical-engineering approaches giving sufficient conditions for nearness relations, we show within a logical analysis that these suffer from some deficiencies. Non-engineering approaches to nearness such as the abstract mathematical approach based on proximity spaces do not deal with the implementation aspects but axiomatically formalize intuitions on nearness relations and provide insights on their nature. Combining the ideas of the engineering approach with the mathematical approach of proximity spaces, we define and analyze new nearness relations that provide a good compromise between implementation needs and the need for an appropriate approximation of the natural nearness concept.

Published: February 2025

This paper describes our ongoing work on developing a Master Orientation Tool for University College Maastricht (UCM). UCM Bachelor students use the tool to discover Master programs that fit their academic profiles. The tool includes a memory-based collaborative recommender system. The system memory contains data on academic profiles of UCM alumni students, labeled by the Master programs they have chosen. The tool operates as a collaborative system: given the academic profile of a Bachelor student, it recommends Master programs for that student based on the proximity of her profile to the profiles of the alumni. The Master Orientation Tool allows students to modify their own profiles and thus to explore alternatives in their study and how they influence their Master program possibilities. The tool is operational at UCM since September 2011 and is popular among the students.
Logical Analysis for Chance Discovery in Multi-Agents’ Environment
Authors: Rybakov Vladimir V.
Published: February 2025

Our paper studies Chance Discovery (CD) in terms of temporal multi-agent logic. Prime question is how to express most essential properties of CD in terms of temporal branching time multi-agents’ logic; how to define CD by formulas in this logical language.We, as an example, introduce several formulas in the language of temporal multi-agent logic which may express essential properties of CD. In the second part of this paper we study computational questions concerning suggested logic. Using some light modification of the standard filtration technique we show that the logic has the finite-model property with effectively computable upper bound. This proves that the logic is decidable and provides a decision algorithm. Thus, we may identify equivalence of statements about CD (in terms of suggested logic) and recognize satisfiable and contradictory statements.
Sticky Tsugoes underlying Sticky Information
Authors: Ohsawa Yukio  , Horie Kenichi  , Akimoto Masahiro
Published: February 2025

Sticky information proposed by von Hippel is known to well explain the localization of innovations, i.e., the tendency of information to be localized in the hands of either inventors in the industrial side or consumers makes it hard for information about needs and seeds meet in the market. In this paper, we break sticky information into sticky tsugoes, where a tsugo is a triple of the intention and two types of constraints behind each stakeholder’s acting/planning. We accumulated cases of Innovators Marketplace ® (IM hereafter) - a serious gaming process for innovative workshop involving multidisciplinary stakeholders, and visualized the interaction of their tsugoes by using KeyGraph. As a tentative result, the variation of human-tsugo network (HTN) explains the performance of innovations more finely than the graph visualizing the relations among participants and sheer information represented by words in the dialogues.

A Variability Model for Query Optimizers
Authors: Soffner Michael  , Siegmund Norbert  , Rosenmüller Marko  , Siegmund Janet  , Leich Thomas  , Saake Gunter
Published: February 2025

By adopting to more domains, database management systems (DBMSs) increase their functionality continously. This leads to DBMSs that often include unnecessary functionality, which decreases performance. A result of this trend is that new specialized systems arise that focus only on a certain application scenario but often reimplement already existing functionality. To avoid bloated DBMSs, we propose to introduce variability in DBMS implementations that allows users to select only needed functionality for a specific application scenario. In this paper, we focus on the query optimizer as it is a key component of DBMSs. We describe the potentials of tailoring query optimizers. Furthermore, we analyze common and differing functionality of three query optimizers of industrial DBMSs (SQLite, Oracle, and PostgreSQL) to create a variability model for query optimizers that can be used as a basis for future variability-aware implementations.
Stable Partial Information Extraction: A Self-Evolving Hybrid Mechanism
Authors: Gao Peng  , Han Hao  , Tokuda Takehiro
Published: February 2025

The Internet is providing a huge amount of information/knowledge through Web pages. For personal and effective use of such resources, the partial information extraction technology breaks a new path to enable end-users to obtain and integrate only needed information from various Web pages into original compositions. However the traditional XPath-only extraction method would fail in case Web sites use different templates to construct Web pages or change the layout of Web pages, which we call as the stability problem. In this paper, we propose a novel hybrid extraction mechanism for stably extract the partial information. We compare the original and changed Web pages to get the unchanged nodes as a stable-part list and use them to generate new paths. Since the list will be re-ranked after new stable-parts are found, the success rates of extraction can be self evolving and correspondingly reduce manual intervention. We show the usefulness of our approach by experiment on real Web sites in practice.
Combined loading of shallow foundations: Application to offshore wind turbines
Authors: Byrne B.W.
Published: February 2025

Combined loading of shallow foundations is where a horizontal and/or moment load is applied to the foundation, in addition to the vertical load. This is one of the classic problems in geotechnical engineering. For offshore engineering applications the combined loading can be particularly severe due to wind and wave forces. As well, the cyclic nature of the loading means that assessing the structural dynamics is important, particularly if the structure is quite flexible, and this requires an accurate assessment of the foundation stiffness. Therefore to model properly both the static and dynamic behaviour of the structure requires linking the structural analysis with the foundation design, and ensuring that any changes in foundation stiffness are captured. A recent application where this is important is for offshore wind turbines, which feature as a prominent part of the renewable energy policy for many countries around Europe. Whilst a number of turbines are founded on mono-piles the option of using shallow foundations, either in the form of a gravity base or the more novel, but untested, suction caissons, is also pursued. Although the standard approach of using bearing capacity theory for shallow foundations is acceptable it is incompatible with doing dynamic analyses. A more recent approach for foundation modelling based on hardening plasticity captures the non-linearity of the foundation response and is therefore preferred. This paper outlines the offshore wind turbine application and then provides an overview of modelling of shallow foundations, focussing on hardening plasticity models.
Combined loadings of shallow foundations: The case of highly eccentric and inclined loads
Authors: Papadopoulos V.
Published: February 2025

Purpose of this paper is the annotation of the admissible limits of normalized eccentricity in conjunction with the influence of high eccentricity and the inclination of resultant on the bearing capacity of shallow foundations. Representative results are presented calculating the characteristic resistance Rkofrom conventional methods compared with Rk from F.E. analyses under 2D or 3D conditions, using the ratio Rk/Rko. For some simple cases certain correction factors of the conventional methods were confirmed. On the contrary, for high eccentricity under inclined loadings, it seems that the conventional methods underestimate considerably the characteristic resistance Rk. The example of a high bridge in Crete, Greece, which is founded on footings on weak rock, indicates that the limitation of eccentricity in some cases constitutes the most substantial design criterion.
Filter design in geotechnical engineering and the FRAUENAU dam experience
Authors: Heerten G.
Published: February 2025

The use of geosynthetics as filter and drainage layer is increasing worldwide. Based on project specific requirements corresponding products have to be designed and selected, but also be installed without damage, because a potential puncture of geotextiles makes the filter design needless. Analogies for the design of grain filters and geosynthetic filters are presented as well as robustness criteria for a safe installation of geotextiles. In the 80 m high rockfill dam “Frauenau” / Germany geotextiles have been applied in a safety-relevant position in the core of the dam. The dam is in successful operation and condition since about 30 years with long-term monitoring showing very little leachate in the control gallery.
Diversification of environmental geotechnics: Opportunities for geotechnical curricula
Authors: Pantazidou M.
Published: February 2025

After attempting a coarse classification of geoenvironmental topics, this article reflects on the diversity of the geoenvironmental material from two alternate viewpoints with regards to education. One viewpoint considers the expanding theoretical background, while the other focuses on specific emerging applications, some of which can act as bridges to other geotechnical or environmental topics. The paper discusses opportunities for education offered by live links between research and instruction and concludes with some suggested considerations for the geotechnical-geoenvironmental community. These include the design of dedicated courses to teach the expanding knowledge base of environmental geotechnics at institutions leading research efforts, the enrichment of existing courses with selected geoenvironmental applications and the consolidation of the knowledge base in key textbooks in order to support both types of courses.
The soft approach to saving monuments and historic sites
Authors: Calabresi G.
Published: February 2025

The flexibility and abundance of technical means and their progressively decreasing costs are often making easier a coarse approach to the restoration of heritage buildings, which alters their original design and construction materials. When an intervention is necessary, the focus should be on reinstating the conditions that enabled them to reach us and preserve their material integrity, also in the parts that are not visible, since the ancient monuments are not mere icons, but tangible, material witnesses of the history of mankind. The geotechnical solutions and technologies developed in recent years offer new and interesting ways to a respectful restoration of heritage buildings. This approach, which can be defined as a soft approach, is gradually gaining ground, as it can be seen in some cases, but it is still not generally understood.
Wireless digital information transfer: modelling, prediction and assessment
Authors: Lager Ioan E.  , de Hoop Adrianus T.  , Kikkawa Takamaro
Published: February 2025

The loop-to-loop pulsed electromagnetic field wireless signal transfer is investigated with a view on its application in wireless digital information transfer. Closed-form expressions are derived for the emitted magnetic field and for the open-circuit voltage of the receiving loop in dependence on the mutual orientation of the loops and the characteristics of the feeding pulse. Numerical results are given for some configurations that are representative for microelectronic wireless signal transfer. In them, the transmitting loop is excited with a monocycle pulse electric current and with a propitious, causal, ultra wide-band pulse. The results are indicative for the potentialities of the pulsed-field wireless signal transfer concerning the received signal characteristics and the system's compliance with regulatory specifications on ElectroMagnetic Emission.
Array-structure theory of Maxwell wavefields in affine (3 + 1)-spacetime: An overview
Authors: de Hoop Adrianus T.
Published: February 2025

An array-structure theory of Maxwell wavefields in affine (3 + 1)-spacetime is presented. The structure is designed to supersede the conventional Gibbs vector calculus and Heaviside vectorial Maxwell equations formulations, deviates from the Einstein view on spacetime as having a metrical structure (with the, non-definite, Lorentz metric), and adheres to the Weyl view where spacetime is conceived as being affine in nature. In the theory, the electric field and source quantities are introduced as one-dimensional arrays and the magnetic field and source quantities as antisymmetrical two-dimensional arrays. Time-convolution and time-correlation field/source reciprocity are discussed, and expressions for the wavefield radiated by sources in an unbounded, homogeneous, isotropic, lossless embedding are derived. These expressions clearly exhibit their structure as convolutions in spacetime. The bookkeeping of the array structure smoothly fits the input requirements of computational software packages. An interesting result of fundamental physical importance is that the ‘magnetic charge’ appears as a completely antisymmetrical three-dimensional array rather than as a number (as in the Dirac quantum theory of the magnetic monopole). The generalization of the array structure to affine (N + 1)-spacetime with N > 3 is straightforward and is conjectured to serve a purpose in theoretical cosmology. No particular ‘orientation’ of the observer's spatial reference frame (like the ‘right-handedness’ in conventional vector calculus) is required.
A hybrid electromagnetics-circuit simulation method exploiting discontinuous Galerkin time domain finite element method
Authors: Li Ping  , Jiang Li Jun
Published: February 2025

A hybrid electromagnetics (EM)-circuit simulation method employing the discontinuous Galerkin finite element time domain method (DGFETD) is developed to model single lumped port networks comprised of both linear and non-linear elements. The whole computational domain is split into two subsystems. One is the EM subsystem that is analyzed by the DGFETDwhile another is the circuit circuit subsystem that is modeled by the Modified Nodal Analysis method (MNA) to generate a circuit subsystem. The coupling between the EM and circuit subsystems is achieved through a lumped port. Due to the local properties of DGFETD operations, only small coupling matrix equation systems are involved. To solve non-linear devices, the standard Newton-Raphson method is applied to solve the established non-linear system equations. Numerical examples are presented to validate the proposed algorithm.

This novel software architecture allows flexible coupling and implementation of existing simulation software suits.
Visual Planning and Scheduling of Industrial Projects with Spatial Factors
Authors: Semenov Vitaly  , Anichkin Anton  , Morozov Sergey  , Tarlapan Oleg  , Zolotov Vladislav
Published: February 2025

With the increasing complexity and scale of industrial projects the need of comprehensive and trustworthy methods for planning and scheduling becomes more and more apparent. Being implemented in recent project management systems, the traditional methods aid in project scheduling based on activity durations, precedence relationships, explicit timing constraints, and resource limits all assumed by Resource-Constrained Project Scheduling Problem (RCPSP). However, the methods have many shortcomings for the industrial projects where spatial factors play critically important role. The objective of this paper is to present an advanced Visual Scheduling Method (VSM) for solving Generally Constrained Project Scheduling Problem (GCPSP) that extends the classical RCPSP statement by taking into account additional spatial factors such as product element collisions, missing of supporting neighbouring elements, workspace congestion. In the paper we provide a holistic framework of the method as well as illustrate how feasible project schedules can be generated under complex spatio-temporal constraints in highly automatic and visually interpretable way. A software implementation of the method and its prospects for application in industrial practice are discussed too.

Published: February 2025

Strategic decisions in early production planning phases have a high impact on various production aspects. Decision making is often based on vague expert knowledge due to lack of a reliable knowledge base. Implications of this problem are especially observable in the field of assembly planning, which integrates results from various planning disciplines. This paper introduces a new concept and the corresponding data model for application of Data Mining (DM) methods in the field of production assembly planning and product design. The approach contains the usage of existing planning data in order to extrapolate assembly processes. Especially linked product and process data allow the innovative usage of Data Mining methods. The concept presents assistance potentials for development of new products variants along the product emergence process (PEP). With this approach an early cost estimation of assembly processes in series production can be achieved using innovative Data Mining methods. Furthermore, design and planning processes can be supported effectively.
A Framework for Completeness in Requirements Engineering: An Application in Aircraft Maintenance Scenario
Authors: Zenuna Marina M.N.  , Loureiro Geilson
Published: February 2025

This paper presents a framework for Completeness in Requirements Engineering (RE) to be used by civil aircraft industry in order to achieve a sufficient degree of completeness in requirements. In civil aircraft industry, completeness is crucial to the success of product development, where a missing requirement can mean a missing attribute. The completeness of requirements is such a need, and at the same time it is a huge challenge. In order to improve the requirements elicitation processes, in a manner that all requirements receive the same level of attention, this work proposes a framework which considers the entire system life cycle, all processes, and people involved. The proposed framework is applied in civil aircraft maintenance scenario, starting at the early stages of development, achieving a sufficient degree of completeness in civil aircraft for maintenance.

In this paper, we investigate errors in syntax annotation with the Turku Dependency Treebank, a recently published treebank of Finnish, as study material. This treebank uses the Stanford Dependency scheme as its syntax representation, and its published data contains all data created in the full double annotation as well as timing information, both of which are necessary for this study.
Architectural contextualism and emerging hybrid morphologies: the case of Olympic Sculpture Park for the Seattle Art Museum
Authors: Kömez Esin
Published: February 2025

Infrastructure networks have always been the primary feature of urbanism. As with any aspects of urban environments, the understanding of infrastructure networks and their practices have witnessed changes due to the shifts first to the modernist ideal and then to the globalised world view. In opposition to the former fragmented nature of infrastructure networks, modern urbanism proposed centralised, standardised and ordered planning of infrastructures. However, this coherent understanding is abandoned as globalisation and its economic organisation trigger liberalisation and privatisation of infrastructure, which leads to ‘splintering urbanism’, a term coined by Graham and Marvin (2001). In addition to these developments, the process of deindustrialisation converted the industrial sites of modern planning into problematic urban areas. Industries were moved away and networks that once served to integrate these areas were decayed, became obsolete and started to split urban areas. These changing urban conditions demand new spatial configurations.
DSS Professional network: A platform for Supporting coordination and social-networking in a WEB-based Decision Support System

Published: February 2025

Web 2.0 is quickly growing because contents are mostly generated by users and it represents now a wide and borderless source of information that can be used for innovation purposes. In this paper, we envisage a combination of Software agents and Web 2.0 technologies within a platform of a Web-Based Decision Support System, the coordination among the Production Agents (PA) in our approach is made possible by a dynamic agent coordination protocol in which sorting solutions are modeled and filtered by using Analytical Hierarchy Process methodology (AHP). This paper develops a simple framework to help understand the collaboration that is afforded by Web 2.0 applications. The proposed framework is used to examine how production agents can create, share and exchange experiences on diagnosis and resources failures with each other to have new ideas or useful information for the decision-making process. ALFATRON electronics industry is selected as an application domain in this study. Agents are communicating by using the JADE plate form.
The implementation of the European Commission recommendation on open access to scientific information: comparison of national policies
Authors: Lomazzi Lisiane  , Chartron Ghislaine
Published: February 2025

Two years after the publication of the European Commission recommendation on open access to scientific information, the critical threshold of accessibility to fifty percent of papers has been crossed. However, this figure is an average and the implementation of the EC recommendation varies from one country to another. The topical issue now is to observe the different steps of implementation and to wonder about the reaseons of such a disparity. In order to suggest many elements of the response, this research compares the different levels of implementation in the EU28.
From Default and Autoepistemic Logics to Disjunctive Answer Set Programs via the Logic of GK
Authors: Ji Jianmin  , Strass Hannes
Published: February 2025

We show how the pure logic of GK can be embedded into disjunctive logic programming. The translation we present is polynomial, but not modular, and introduces new variables. The result can then be used to compute the extension/expansion semantics of default and autoepistemic logics using disjunctive ASP solvers.
Modular Behavior Trees: Language for Fast AI in Open-World Video Games
Authors: Plch Tomáš  , Marko Matěj  , Ondráček Petr  , Černý Martin  , Gemrot Jakub  , Brom Cyril
Published: February 2025

As the graphical representation of computer games gradually becomes comparable to cinema, previously neglected non-graphical game aspects start to play an important role in maintaining believability of the game world. One such aspect is the behavior of non-player characters (NPCs), which should appear intelligent and purposeful in the ideal case or not completely stupid at the very least. A good and fast language to express the behaviors is vital for success. We present a visual agent language inspired by behavior trees that was approved for deployment at the core of AI system for an upcoming high-budget open world game.
Taking the Long View: Looking Ahead in Practical Reasoning
Authors: Atkinson Katie  , Bench-Capon Trevor
Published: February 2025

In this paper we extend an argumentation scheme for practical reasoning with values based on Action-based Alternating Transition Systems. While the original scheme considers only arguments arising from the immediately next state, our proposals will enable long term considerations to be taken into account. We consider the various reasons for and against performing an action that arise from these longer term considerations, and develop a new set of argumentation schemes for practical reasoning which allows a clearer separation between facts, values and preferences, and more precise targeting of attacks.
Argument Mining and Social Debates
Authors: Carstens Lucas  , Toni Francesca  , Evripidou Valentinos
Published: February 2025

With this demonstration we introduce AFAlpha, a prototype of an Argument Mining tool, working in unison with Quaestio-it, an online social debating platform. While AFAlpha extracts arguments from text, as well as attack and support relations between arguments, Quaestio-it is concerned with visualising and evaluating interactive debates. We thus use Quaestio-it to represent and visualise output from AFAlpha, with the goal of taking plain text, in our case online reviews, and representing it in the form of a debate.
OVA+: an Argument Analysis Interface

An Ontological Core for Conformance Checking in the Engineering Life-cycle
Authors: Jordan Andreas  , Selway Matt  , Mayer Wolfgang  , Grossmann Georg  , Stumptner Markus
Published: February 2025

Effective exchange of information about processes and industrial plants, their design, construction, operation, and maintenance requires sophisticated information modelling and exchange mechanisms that enable the transfer of semantically meaningful information between a vast pool of heterogeneous information systems. In order to represent entities relevant to the engineering life-cycle, social concepts, descriptions, roles, artefacts, functions, and information objects must be integrated in a coherent whole. Forming the basis of this integration in our framework is the DOLCE foundational ontology. In this paper we propose an ontologically well-founded approach to modelling artefacts, their requirement specifications and functional roles, such that consistency of their relationships in the data model can be verified. Specifically, we discuss the modelling of engineering artefacts, roles and role-filling capacity in the context of data modelling for industrial information exchange.
Using the ToBI Transcription to Analyze the Intonation of Lithuanian
Authors: Krapikaitė Neringa
Published: February 2025

The most convenient tool for prosody research can be at least minimally annotated speech corpus and properly prepared speech labelling system based on common methodology widely used by foreign researchers. One of the most popular standards for annotation and transcription of prosodic events is ToBI (an acronym for Tones and Break Indices). This paper outlines the use of ToBI transcription system for the transcription of Lithuanian intonation and the future research in the area of prosody.
