    Odour classification system for continuous monitoring applications2009Inngår i: Sensors and actuators. B, Chemical, ISSN 0925-4005, E-ISSN 1873-3077, Vol. 58, nr 2, s. 265-273Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this paper, we investigate the classification performance of an electronic nose system, based on tin dioxide gas sensors. In contrast to previous studies, the electronic nose is mounted on a mobile platform and samples are analyzed using only transient information in the signals. The motivation behind this work is to explore the feasibility of using electronic nose devices for odour classification in a number of future application domains which require fast and possibly real-time odour identification. To perform transient based analysis of the signals, a comparative study of different methods for feature extraction was performed. Additionally, the application of a relevance vector machine classifier is explored to further analyze the classification performance based on quality of the obtained samples. The results presented in this study can be used for the development of electronic nose devices particularly suitable for environmental monitoring applications.

    Online classification of gases for environmental exploration2009Inngår i: IEEE/RSJ international conference on intelligent robots and systems, IROS 2009, New York: IEEE, 2009, s. 3311-3316Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In this paper we investigate how a mobile robot equipped with tin dioxide gas sensors and an anemometer can use an online classification algorithm in order to improve the exploration strategy. The purpose of the platform is to establish the character of a gas source with accuracy while minimizing the time required for exploration. For this to be possible, the output of the classification algorithm is probabilistic, feeding in a sequence of posterior probabilities to a path planner. To further assist path planning, a 3d-ultrasonic anemometer is available which give indication on the average wind speed and direction. In addition to evaluating different olfaction driven path planning strategies, experimental validations also evaluate the classification algorithms and its application to different environments with varying characteristics.

    Direct identification of bacteria in blood culture samples using an electronic nose2010Inngår i: IEEE Transactions on Biomedical Engineering, ISSN 0018-9294, E-ISSN 1558-2531, Vol. 57, nr 12, s. 2884-2890Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this paper, we introduce a method for identification of bacteria in human blood culture samples using an electronic nose. The method uses features, which capture the static (steady state) and dynamic (transient) properties of the signal from the gas sensor array and proposes a means to ensemble results from consecutive samples. The underlying mechanism for ensembling is based on an estimation of posterior probability, which is extracted from a support vector machine classifier. A large dataset representing ten different bacteria cultures has been used to validate the presented methods. The results detail the performance of the proposed algorithm and show that through ensembling decisions on consecutive samples, significant reliability in classification accuracy can be achieved.

    A Least Squares approach for learning gas distribution maps from a set of integral gas concentration measurements obtained with a TDLAS sensor2012Inngår i: Proceedings of the IEEE Sensors Conference, 2012, IEEE Sensors Council, 2012, s. 550-553Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Applications related to industrial plant surveillance and environmental monitoring often require the creation of gas distribution maps (GDM). In this paper an approach for creating a gas distribution map using a Tunable Diode Laser Absorption Spectroscopy (TDLAS) sensor and a laser range scanner mounted on a pan tilt unit is presented. The TDLAS sensor can remotely sense the target gas, in this case methane, requiring novel GDM algorithms compared to the ones developed for traditional in-situ chemical sensors. The presented setup makes it possible to create a 3D model of the environment and to calculate the path travelled by the TDLAS beam. The knowledge of the beam path is of crucial importance since a TDLAS sensor provides an integral measurement of the gas concentration over that path. An efficient GDM algorithm based on a quadratic programming formulation is proposed. The approach is tested in an indoor scenario where transparent bottles filled with methane are successfully localized.

    An inspection of signal dynamics using an open sampling system for gas identification2010Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Odour discrimination with a sensor array directly exposed to the environment is of great interest in many applications ranging from environmental monitoring to search and rescue and exploration of hazardous areas. Metal oxide based sensors are typically used in such applications for gas detection as they are compact, low costing and exhibit fast response time to an analyte. Given the characteristics of the metal oxide sensors as well as the chaotic nature of the airflow in a natural environment, it has been assumed that a reliable odour discrimination system working in this condition has to work with features that capture the transient characteristics of the signal. In this work we present an experimental setup that enables a deeper insight into transient-based analysis for open sampling systems. Observations on the  properties of the signal collected under a controlled experimental condition using an open sampling system are presented. These observations suggest that in a scenario in which the sensors are exposed to different compounds without the possibility to recover the baseline value in between a gas identification, a model of the dynamics of the system is needed and a notion of the sensor state should be maintained that captures the past history of the sensor response.

    Feature selection for gas identification with a mobile robot2010Inngår i: 2010 IEEE International Conference on Robotics and Automation (ICRA), IEEE conference proceedings, 2010, s. 2852-2857Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    In this paper we analyze the problem of discrimination of gases with mobile robots. Previously, it has been shown that the conditions in which data is collected heavily influence the characteristics of the signal to be identified. As a result, the already difficult task of selecting features which characterize a gas is made more challenging by the absence of a steady state response. This is often due to the movement of the robot, and/or the physical properties of the environment, e. g., turbulent airflow creating patches and eddies in the plume. In this work we compare two approaches for feature selection which are able to consider explicitly the information on the experimental setup and optimize the subset of features used in the recognition process. The approaches are tested on a large data set collected with a mobile robot moving in different environments (outdoors and indoors). The results show that the classification performance is improved resulting in a higher average accuracy and lower variance in the accuracy across the different experimental setups.

    Towards environmental monitoring with mobile robots2008Inngår i: 2008 IEEE/RSJ International Conference on Intelligent Robots and Systems, New York, NY, USA: IEEE, 2008, s. 2210-2215, artikkel-id 4650755Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In this paper we present initial experiments towards environmental monitoring with a mobile platform. A prototype of a pollution monitoring robot was set up which measures the gas distribution using an “electronic nose” and provides three dimensional wind measurements using an ultrasonic anemometer. We describe the design of the robot and the experimental setup used to run trials under varying environmental conditions. We then present the results of the gas distribution mapping. The trials which were carried out in three uncontrolled environments with very different properties:

    an enclosed indoor area, a part of a long corridor with open ends and a high ceiling, and an outdoor scenario are presented and discussed.

    Optimizing the operating temperature for an array of MOX sensors on an open sampling system2011Inngår i: Olfaction and electronic nose: Proceedings of the 14th international symposium on olfaction and electonic nose, 2011, s. 225-227Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Chemo-resistive transduction is essential for capturing the spatio-temporal structure of chemical compounds dispersed in different environments. Due to gas dispersion mechanisms, namely diffusion, turbulence and advection, the sensors in an open sampling system, i.e. directly exposed to the environment to be monitored, are exposed to low concentrations of gases with many fluctuations making, as a consequence, the identification and monitoring of the gases even more complicated and challenging than in a controlled laboratory setting. Therefore, tuning the value of the operating temperature becomes crucial for successfully identifying and monitoring the pollutant gases, particularly in applications such as exploration of hazardous areas, air pollution monitoring, and search and rescue I. In this study we demonstrate the benefit of optimizing the sensor's operating temperature when the sensors are deployed in an open sampling system, i.e. directly exposed to the environment to be monitored.

    An anatomy of requirements engineering in software startups using multi-vocal literature and case survey2018Inngår i: Journal of Systems and Software, ISSN 0164-1212, E-ISSN 1873-1228, Vol. 146, s. 130-151Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Context: Software startups aim to develop innovative products, grow rapidly, and thus become important in the development of economy and jobs. Requirements engineering (RE) is a key process area in software development, but its effects on software startups are unclear. Objective: The main objective of this study was to explore how RE (elicitation, documentation, prioritization and validation) is used in software startups. Method: A multi-vocal literature review (MLR) was used to find scientific and gray literature. In addition, a case survey was employed to gather empirical data to reach this study's objective. Results: In the MLR, 36 primary articles were selected out of 28,643 articles. In the case survey, 80 respondents provided information about software startup cases across the globe. Data analysis revealed that during RE processes, internal sources (e.g., for source), analyses of similar products (e.g., elicitation), uses of informal notes (e.g., for documentation), values to customers, products and stakeholders (e.g., for prioritization) and internal reviews/prototypes (e.g., for validation) were the most used techniques. Conclusion: After an analysis of primary literature, it was concluded that research on this topic is still in early stages and more systematic research is needed. Furthermore, few topics were suggested for future research. © 2018 Elsevier Inc.

    Monitoring quality of service at Australian airports: A critical analysis2018Inngår i: Journal of Air Transport Management, ISSN 0969-6997, E-ISSN 1873-2089, Vol. 67, s. 63-71Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The quality of service monitoring forms a key element of the current light-handed regulation at Australian airports. The ACCC (Australian Competition and Consumer Commission) evaluates and publicly reports the quality of service levels of the four largest airports on a yearly basis to pressure airports to maintain an acceptable service performance. This article aims to provide an in-depth analysis of the methodology used by the ACCC. This analysis includes a critical review of the methodology based on secondary information in combination with primary research (i.e., data from 21 semi-structured interviews) that considers the current perception of the methodology among key stakeholder groups. The research finds that the methodology used by the ACCC is underpinned by some limitations, putting in question its effectiveness, reliability and validity. Particularly, its weak design does not allow for a comprehensive interpretation of the reported results or a reliable comparison across monitored airports, thus reduces transparency. Stakeholders pointed out that it is not possible to evaluate whether an airport undertakes infrastructure investments that ensure both the efficiency of ongoing airport operations and appropriate levels of service quality. These limitations add to the perception that the ACCC in its current function is not a ‘credible threat’ to airports with market power. Recommendations and future research directions are provided to address the identified limitations.

    Prerequisites for data sharing in emergency management: joint analysis using a real-time role-playing exercise approach2007Licentiatavhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    This thesis explains how semi-coordinated or separated utilization of information and communication technologies may affect collaborative work between different emergency management organizations, and their capabilities to perform joint tasks during emergency responses. Another aim is to explore the modeling of emergency management and data collection methods with respect to utilization of these technologies.

    The theoretical basis for the thesis consists of system science, cognitive system engineering, communication, informatics, simulation, emergency management, and command and control. Important notions are the joint cognitive systems concept and the communication infrastructure concept. The case study method and the real-time role-playing exercise approach are the main methodological approaches.

    On the basis of two main studies, geospatial data and related systems are studied as an example. Study I focuses on emergency management organizations' abilities to collaborate effectively by assessing their communication infrastructure. Study II, on the other hand, highlights the emerging effects in use of data in collaborative work when responding to a forest fire scenario.

    The results from the studies, and from the general work conducted and presented here, show that the semi-coordinated or separated utilization of the technologies affects (a) how well the organizations can collaborate, (b) the capabilities to carry out collaborative tasks during crises and disasters, and (c) to what extent the technology can be used in real-life situations. The results also show that the joint cognitive system notion and the real-time role-playing exercise approach provided new ways to conceptualize and study the emergency management and the command and control system.

    Using Low-Fidelity Simulations to Support Design of Decision-Support Systems for Command and Control Applications2008Inngår i: Distributed Multimedia Systems,2008, Skokie, IL, USA: Knowledge Systems Institute , 2008, s. 158-Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Modern decision-support systems for command and control may lead to radical organizational and technological changes. This paper describes a methodology to support designers and developers of such system in order to identify this type of changes in the design process. The methodology is based on a shorter series of low-fidelity simulations. The analyses do not focus on individual actions of the decision-support system operators, but instead on impacts of the systems on situated and joint actions of the command and control teams in terms of communication and coordination. The simulation series presented in the paper shows how the use of a decision-support system combining real-time data from various sensors led to changes in the content and structure of the communication as well as the resource coordination. Findings from the discussed simulations suggest that more attention should be given to possible impacts of decision-support systems on the joint actions of the command and control teams, as well as how these teams- actions are situated within the larger command and control system.

    Abstract [en]

    In this paper, methodological issues in research and training of complex command and control structures in emergency management are addressed. In particular, a methodological approach combining real-time role-playing exercise, after action review and observations is presented. An explorative study - ALFA-05 - utilizing this approach is described. A brief overview of methodological aspects of preparation and execution is given. Further, experience gained and methodological lessons learned are also discussed. Finally, real-time role-playing exercise in combination with other methods is suggested as a feasible method for researchers and exercise managers to tackle present and future command and control in complex settings, where interaction and communication are in focus. In addition, areas for further development of the real-time role-playing exercises as a research method are suggested.

    Information Support in Collaborative Command and Control Work - An Empirical Research Using a Role-Playing Exercise Approach2006Inngår i: International Command and Control Research and Technology Symposium,2006, 2006Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This research aims at improving knowledge on design of computer-supported command and control systems. In particular, aspects of communication and information seeking are investigated. The method of role-playing exercises is presented and some empirical data from a study using that method is presented. A role-playing exercise is a real-time approach where participants act in their professional roles to manage various situations in a collaborative matter. In this case, a forest-fire together with additional incidents was used in order to study collaborative command and control work between commanding officers from different organizations, such as police, fire & rescue and emergency call-centers. Commanders- local knowledge and experience from similar events are factors influencing information seeking. Other types of information are seen as additional, and further information seeking depends on the dynamics of the events and the workload. The essential contribution of the role-playing exercise approach lays in its possibilities to document and identify differences between planned and intended command and control processes and real command and control work.

    Inter-organizational Issues in ICT, GIS and GSD - Mapping Swedish Emergency Management at the Local and Regional Level2005Inngår i: Proceedings of the 2nd International Conference on Information Systems for Crisis Response and Management (ISCRAM) / [ed] Van de Walle, B. & Carlé, B., Tilburg, Netherlands: Tilburg University , 2005, s. 75-82Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Inter-organizational issues are very challenging in emergency management (EM). In this paper, aspects of information and communication technologies (ICT), geographical information systems (GIS) and geospatial data (GSD) in the Swedish EM system, an EM system involving a large number of EM organizations, are reported based on a case study. The issues concerned include separated ICT & GIS development between organizations and formation of technological coalitions, problems of identification and access of GSD, located through the large number organizations, as well as uncoordinated launching of web-based GIS service. Possible implications of this situation for command and control are discussed. Additionally, areas for further research are suggested.

    Utilization and Exchange of Geospatial Data in Swedish Emergency Management2005Inngår i: ScanGIS' 2005: proceedings of the 10th Scandinavian Research Conference on Geographical Information Sciences / [ed] H. Hauska & H. Tveite, Stockholm, Sweden: Universitetsservice US AB , 2005, s. 53-62Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In this paper, research investigating the current situation with respect to geospatial data (GSD) access and integration at the interorganizational level in Swedish local and regional emergency management (EM) is presented. The performed analysis resulted in a range of conceptual, organizational, administrative and ontological problems, recognized by the international research community and also identified among the studied Swedish EM organizations. Additionally, close interconnection between particular problems or groups of problems was observed in several cases. The documented findings can be seen as hindering the sharing of GSD. Moreover, development of useful GIS-based analytical and decision-support applications for day-to-day use in EM is becoming difficult without effectively sharing GSD. It is suggested to promote further research in an integrated way to understand the full complexity of the problems. Moreover, involving both the research and EM communities is seen as essential.

    Framtida Ledningscentraler: Slutrapport2011Rapport (Annet vitenskapelig)
    Abstract [sv]

    Denna rapport redovisar projektet "FM framtida ledningscentraler". Syftet med rapporten är att skapa ett underlag för att stödja utformning av FM ledningscentraler genom att kartlägga aktuell forskning och sammanställa erfarenheter inom området ledningscentraler samt att ta fram de faktorer som kan påverka utformning av ledningscentraler på medellång till lång sikt. Resultatet från arbetet baseras på en övergripande analytisk strategi, bestående av litteraturstudie, kartläggning av militära FoU-projekt, workshop med inriktning på ledningscentraler i Sverige, analys av utvalda ledningscentraler i Sverige och utomlands samt intervjuer med fokus på FM ledningscentraler. Denna rapport omfattar inte ledningsmetodik, annat än i den omfattningen att det direkt påverkar utformning av ledningscentraler. De identifierade påverkansfaktorerna beskrivs och diskuteras inom fyra temaområden: utformning av flerrumslösningar, arbetsmiljö och ergonomi, tekniska hjälpmedel och förändringshantering. Utifrån resultatet görs en reflektion kring den genomförda analysen och de identifierade påverkansfaktorerna som skapar en grund för FM att ta fram beslutsunderlag för att utforma framtida FM ledningscentraler.

    Nedskalad truminspelning med ett stort sound: Om Kevin Parker och hans sätt att producera trummor2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Producenten Kevin Parker har onekligen fått igenkänning för sitt trumsound. Som

    huvudsaklig låtskrivare och producent i rockbandet Tame Impala har han skapat sig ett

    ”signature sound”. Eftersom många gillar hur Parkers trummor låter har det förts långa

    diskussioner angående produktionsprocessen. Uppsatsen ämnade att ta reda på hur

    Parkers produktion sett ut och vilka ljudliga artefakter det är som utgör hans sound.

    Resultatet visar på en väldigt nedskalad inspelning. Ofta med ett enkelt vintage-trumkit

    och tre till fyra mikrofoner, dämpade skinn samt en hel del kompression och distorsion.

    Soundet kan beskrivas som väldigt energiskt, mycket tack vare just hård kompression

    och distorsion. Parkers sound känns igen även utanför Tame Impala. Trummorna

    upplevs i många fall som mycket mer än bara ett rytminstrument. Uppsatsen förklarar

    hur okonventionella produktionsprocesser kan ge upphov till originella ljudliga

    karaktärer, vilket i slutändan kan anses en positiv konsekvens.

    Positioning of Nuclear Fuel Assemblies by Means of Image Analysis on Tomographic Data2004Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    A tomographic measurement technique for nuclear fuel assemblies has been developed at the Department of Radiation Sciences at Uppsala University [1]. The technique requires highly accurate information about the position of the measured nuclear fuel assembly relative to the measurement equipment. In experimental campaigns performed earlier, separate positioning measurements have therefore been performed in connection to the tomographic measurements.

    In this work, another positioning approach has been investigated, which requires only the collection of tomographic data. Here, a simplified tomographic reconstruction is performed, whereby an image is obtained. By performing image analysis on this image, the lateral and angular position of the fuel assembly can be determined. The position information can then be used to perform a more accurate tomographic reconstruction involving detailed physical modeling.

    Two image analysis techniques have been developed in this work. The stability of the two techniques with respect to some central parameters has been studied. The agreement between these image analysis techniques and the previously used positioning technique was found to meet the desired requirements. Furthermore, it has been shown that the image analysis techniques offer more detailed information than the previous technique. In addition, its off-line analysis properties reduce the need for valuable measurement time.

    When utilizing the positions obtained from the image analysis techniques in tomographic reconstructions of the rod-by-rod power distribution, the repeatability of the reconstructed values was improved. Furthermore, the reconstructions resulted in better agreement to theoretical data.

    Experimental multipartner quantum communication complexity employing just one qubit2013Inngår i: Natural Computing, ISSN 1567-7818, E-ISSN 1572-9796, Vol. 12, nr 1, s. 19-26Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Most proposals for quantum solutions of information-theoretic problems rely on the usage of multi-partite entangled states which are still difficult to produce experimentally with current state-of-the-art technology. Here, we analyze a scheme to simplify a particular kind of multiparty communication protocols for the experiment. We prove that the fidelity of two communication complexity protocols, allowing for an N - 1 bit communication, can be exponentially improved by N - 1 (unentangled) qubit communication. Taking into account, for a fair comparison, all inefficiencies of state-of-the-art set-up, the experimental implementation for N = 5 outperforms the best classical protocol, making it the candidate for multi-party quantum communication applications.

    A universally composable scheme for electronic cash2005Inngår i: PROGRESS IN CRYPTOLOGY: INDOCRYPT 2005, PROCEEDINGS / [ed] aitra, S; Madhavan, CEV; Venkatesan, R, 2005, Vol. 3797, s. 347-360Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We propose a scheme for electronic cash based on symmetric primitives. The scheme is secure in the framework for universal composability assuming the existence of a symmetric CCA2-secure encryption scheme, a CMA-secure signature scheme, and a family of one-way, collision-free hash functions. In particular, the security proof is not in the random-oracle model. Due to its high efficiency, the scheme is well-suited for devices such as smart-cards and mobile phones. We also show how the proposed scheme can be used as a group signature scheme with one-time keys.

    Electronic Cash and Hierarchical Group Signatures2006Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [sv]

    I denna avhandling presenteras resultat inom två områden – elektroniska betalningar och hierarkiska gruppsignaturer.

    • En starkare säkerhetsdefinition för digitala pengar presenteras med syfte att användare inte ska behöva lita på banken i samma utsträckning som för äldre definitioner. Denna starkare definition ges dels som en experimentbaserad definition och dels som en definition i ramverket för universell sammansättning (UC). Det visas att säkerhet enligt den experimentbaserade definitionen implicerar UC-säkerhet. Dessutom beskrivs en konstruktion med allmänna metoder som är säker enligt den nya definitionen i modellen med gemensam referenssträng (CRS) om den baseras på en familj lönndörrspermutationer.

    I samband med konstruktionen definieras extraherbara, simuleringssunda, icke-interaktiva kunskapslösa bevis. Existensen av sådana bevis i CRS-modellen bevisas under antagandet att det existerar en familj lönndörrspermutationer.

    • Ett system för digitala pengar beskrivs. Systemet bygger på symmetriska primitiv och är säkert i UC-ramverket under antagandet att ett symmetriskt CCA2-säkert kryptosystem, ett CMA-säkert signaturssystem och en familj enkelriktade kollisionsfria hashfunktioner används. Beviset är inte i slumporakel-modellen. Tack vare sin höga effektivitet är system väl lämpat för exempelvis smartkort och mobiltelefoner. Det beskrivs vidare hur systemet kan användas som ett system för gruppsignaturer med engångsnycklar.

    • Begreppet hierarkiska gruppsignaturer introduceras. Detta är en äkta generalisering av gruppsignaturer som tillåter flera gruppchefer organiserade i ett träd med signatörerna som löv. Om en signatör är löv i ett delträd under en gruppchef får denne gruppchef reda på till vilket delträd signatören hör. Definitioner och tre olika konstruktioner ges.

    Den första konstruktionen använder allmänna metoder och är säker om den baseras på en familj lönndörrspermutationer. Denna konstruktion är inte avsedd för praktisk använding, utan ska ses som ett bevis att definitionen är rimlig. Den andra definitionen är nästan praktisk, och dess säkerhet bevisas i slumporakelmodellen under starka RSA-antagandet och DDH-antagandet. Den tredje konstruktionen är praktisk och säker under starka RSA-antagandet och DDH-antagandet. Denna konstruktion är optimistisk i den meningen att en gruppchef kan behöva interagera med andra parter för att öppna en signatur.

    Slutligen bevisas att om ett system för hierarkiska gruppsignaturer är säkert så realiserar det en ideal funktionalitet i UC-ramverket.

    Abstract [en]

    We give a method for approximating any n-dimensional lattice with a lattice A whose factor group Z(n)/Lambda has n - 1 cycles of equal length with arbitrary precision. We also show that a direct consequence of this is that the Shortest Vector Problem and the Closest Vector Problem cannot be easier for this type of lattices than for general lattices.

    Two topics in cryptography: lattice problems and the security of protocols2005Licentiatavhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    In this thesis we present new results in two areas – cryptographic protocols and lattice problems.

    • We present a new protocol for electronic cash which is designed to function on hardware with limited computing power. The scheme has provable security properties and low computational requirements, but it still gives a fair amount of privacy. Another feature of the system is that there is no master secret that could be used for counterfeiting money if stolen.

    • We introduce the notion of hierarchical group signatures. This is a proper generalization of group signatures, which allows multiple group managers organized in a tree with the signers as leaves. For a signer that is a leaf of the subtree of a group manager, the group manager learns which of its children that (perhaps indirectly) manages the signer. We provide definitions for the new notion and construct a scheme that is provably secure given the existence of a family of trapdoor permutations. We also present a construction which is relatively practical, and prove its security in the random oracle model under the strong RSA assumption and the DDH assumption.

    • We show a weakness in the specification for offline capable EMV payment cards. The weakness, which applies to cards without RSA capability, enables an attacker to duplicate a card and make transactions that cannot be tied to the original card.

    • We give a method for approximating any n-dimensional lattice with a lattice Λ whose factor group Zn/Λ has n - 1 cycles of equal length with arbitrary precision. We also show that a direct consequence of this is that the Shortest Vector Problem and the Closest Vector Problem cannot be easier for this type of lattices than for general lattices.

    We introduce the notion of hierarchical group signatures. This is a proper generalization of group signatures, which allows multiple group managers organized in a tree with the signers as leaves. When opening a signature a group manager only learns to which of its subtrees, if any, the signer belongs. We provide definitions for the new notion and construct a scheme that is provably secure given the existence of a family of trapdoor permutations. We also present a construction which is relatively practical, and prove its security in the random oracle model under the strong RSA assumption and the DDH assumption.

    Flyt tillsammans: Emotionell gemenskap i kooperativa spel2011Independent thesis Basic level (degree of Bachelor), 20 poäng / 30 hpOppgave
    Abstract [sv]

    Studien undersöker känslomässiga reaktioner vid kooperativt spelande, vilka som är gemensamma för båda spelarna och hur de påverkas av hur svårt spelet är. Arbetet utgick från studier av spelares emotionella reaktioner på spel och teorierna om Flow. Spelet Sanctum användes i en serie tester där mätningar utfördes på två spelare med hjälp av rapportformulär, pulsmätare och hjärna-till-datorgränssnittet Emotiv EPOC. Studien fann att spelarna ibland upplevde samma känslor när de spelade tillsammans och att den ökade svårighetsgradens huvudsakliga effekt var att förändringarna i känslorna blev skarpare och större. Det tycktes huvudsakligen vara motgångar som splittrade spelarnas upplevelser. Resultaten ansågs tyda på att Flow är det optimala tillståndet för känslorna att växa i, och att ohanterbara situationer desynkroniserar dem. Undersökningen omfattade tio personer och åtta tester.

    Abstract [en]

    Humans are social animals. They realize their dreams and ambitions in relation to other humans, within a context of symphonic diversity. They feel good or bad, mainly in relation to other people. And by doing it, we – the sensual humans – feel with the others, we feel for the others. I believe that the role of Design is to offer tools and ways to learn to deal in a creative, constructive way, how to be together, how to weave these relationships among people, how to play with and transform towards the resistance and the ambiguity that the environment and the people within this environment create, in their constant dynamism. By leveraging on people’s skills, and therefore on their sensitivity, and their urge of transformation, Design can concur in creating and consolidating practices, able to elicit ethical behaviors, building new foundations of social health. Design can elicit health by Making: less noise and more deeds, for a new craftsmanship.

    Designing in Skills - Nurturing Personal Engagement in Design2013Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Potentialities of skills in design are intriguing. Skills open up new perceptions of the world, transform human understanding and engagement with the world itself. Our explorations suggest that leveraging existing designer's skills and training for new skills might remarkably contribute in designing for richness of meaning. We developed several skills-based techniques and validated them through a number of workshops. These techniques encourage participants to make before thinking, to reflect on the outcomes of making, and proceed by iterations of reflection-on-action. Also developed are techniques to increase the frequency of such iterations to minimize loss of meaning by abstraction, and techniques to foster depth of reflection. We organised these techniques into a framework, Designing in Skills (DiS). DiS nurtures personal engagement of designers, compelling a sense of responsibility; it supports designers toward what we call the "first-person perspective", enabling application of individual sensitivities. This paper presents firstly the motivation of our work and the surrounding theory. Subsequently, it introduces the framework and its development, using design cases that have led to its consolidation. It illustrates how DiS prepares for design practice and reflects on the theme of experiential richness.

    Ballade of Women: embodiment to trigger active knowledge2013Inngår i: Proceedings of NODEM, 2013Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Ballade of Women is an interactive exhibition that aims at exploring human rights from a female perspective.

    It leverages on the concept of engagement through embodiment. Visitors of the exhibition are actors of the dynamic landscape that shapes around them and because of them. Visitors, through their sensitivity, interact with the installation, in a continuous dynamic, meaningful dialogue. They learn, grow and form a stance, because they are actively engaged in what they experience, in the dynamic space.

    In one space, the three original paintings are presented and, in another, an interactive installation that plays and elaborates on the themes of each of the three paintings is located. In the installation, representations of these three painting are fragmented, and float in the space, much as the information we have about their subjects has been fragmented by history and politics and the speed of our world. Set on rotating spindles, these fragments resist attempts by the viewer to capture them as a whole. The screens only provide a complete view of the paintings at selected times and from specific view-points in the room. When the screens are positioned in a fragmented way, they display media coming from online groups, discussing issues addressed in the exhibition. The screens’ movement is influenced by the physical presence of observers and by the online discussions.  Software continuously monitors news related to the treated themes and how these are addressed through posts and online discussions. The number of threads created from the internet is an input for the installation and influences the speed of movements and informative content. The soundscape allows the viewer to pick up fragments of the play of a selection of poems, related to the three themes. Verses are whispered and vanish, immediately after being heard.

    This dynamic experience suggests that each of us can contribute to compose a harmonious picture of the complex and controversial world of women's rights, by approaching it, and by being confronted with points of view of other people, facing the same topics from different perspectives all over the world.

    MoCap Tango: Materialising Movement Qualities2016Inngår i: Proceedings of the 2016 CHI Conference Extended Abstracts on Human Factors in Computing Systems (CHI EA '16), 2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This video shows the ongoing design research project MoCap Tango. The project highlights the subtle qualities embedded in the physical dialogue between two tango dancers from a design perspective. Using custom-made wearables fitted with passive markers, in an optical Motion Capture System, the movements of two world-class tango dancers are captured. This data is used to experiment with real-time visualisations and 3D printed materialisations of the movements. The video presents the current state of the project, showing public performances in which the system was used as well as current work to use the data to create animations and 3D printed sculptures. Interviews with part of the design team highlight motivations for the project and discuss its relevance for embodied interaction design.

    Musical Viruses for graceful seduction2012Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The +++ Wearable Player is a result of the application of the Rights through Making approach in designing wearables. This approach aims at designing systems, whose use empowers people towards the materialization of values (e.g. human rights). The +++ Wearable Player system elaborates on the previous project Sound Experience, and introduces the concept of viral music exchange as a motivating factor in the context of social health. This paper describes the morphological genesis, the functional aspects and how they have been implemented in a fully working experienceable prototype. The design process and its outcomes are illustrated, in the framework of the “changing behaviour” design trend.

    Spreading Activation Methods2009Inngår i: Dynamic and Advanced Data Mining for Progressing Technological Development / [ed] Shawkat A, Xiang Y, IGI Global, 2009Kapittel i bok, del av antologi (Fagfellevurdert)
    Abstract [en]

    Spreading activation (also known as spread of activation) is a method for searching associative networks, neural networks or semantic networks. The method is based on the idea of quickly spreading an associative relevancy measure over the network. The goal is to give an expanded introduction to the method. The authors will demonstrate and describe in sufficient detail that this method can be applied to very diverse problems and applications. They present the method as a general framework. First they will present this method as a very general class of algorithms on large (or very large) so-called multidimensional networks which will serve a mathematical model. Then they will define so-called micro-applications of the method including local search, relationship/association search, polycentric queries, computing of dynamic local ranking, etc. Finally they will present different applications of the method including ontology-based text processing, unsupervised document clustering, collaborative tagging systems, etc.
