    Search for supernova neutrino bursts with the AMANDA detector2001In: Astroparticle physics, ISSN 0927-6505, E-ISSN 1873-2852, Vol. 16, no 4, p. 345-359Article in journal (Refereed)
    Abstract [en]

    The core collapse of a massive star in the Milky Way will produce a neutrino burst, intense enough to be detected by existing underground detectors. The AMANDA neutrino telescope located deep in the South Pole ice can detect MeV neutrinos by a collective rate increase in all photo-multipliers on top of dark noise. The main source of light comes from positrons produced in the CC reaction of anti-electron neutrinos on free protons ve + p → e+ + n. This paper describes the first supernova search performed on the full sets of data taken during 1997 and 1998 (215 days of live time) with 302 of the detector's optical modules. No candidate events resulted from this search. The performance of the detector is calculated, yielding a 70% coverage of the galaxy with one background fake per year with 90% efficiency for the detector configuration under study. An upper limit at the 90% c.l. on the rate of stellar collapses in the Milky Way is derived, yielding 4.3 events per year. A trigger algorithm is presented and its performance estimated. Possible improvements of the detector hardware are reviewed.

    Calibration and survey of AMANDA with the SPASE detectors2004In: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, ISSN 0168-9002, E-ISSN 1872-9576, Vol. 522, no 3, p. 347-359Article in journal (Refereed)
    Abstract [en]

    We report on the analysis of air showers observed in coincidence by the Antarctic Muon and Neutrino detector array (AMANDA-B10) and the South Pole Air Shower Experiment (SPASE-1 and SPASE-2). We discuss the use of coincident events for calibration and survey of the deep AMANDA detector as well as the response of AMANDA to muon bundles. This analysis uses data taken during 1997 when both SPASE-1 and SPASE-2 were in operation to provide a stereo view of AMANDA. © 2003 Elsevier B.V. All rights reserved.

    Limits on diffuse fluxes of high energy extraterrestrial neutrinos with the AMANDA-B10 detector2003In: Physical Review Letters, ISSN 0031-9007, E-ISSN 1079-7114, Vol. 90, no 25, p. 2511011-2511015Article in journal (Refereed)
    Abstract [en]

    A report on the limits, which could be placed on diffuse fluxes of high energy extraterrestrial neutrinos, was presented. The incorporation of neutrino oscillations was necessary for interpreting the limits in terms of the flux from a cosmological distributions of sources. The energetic accelerated environments were presented as the sources of high energy extraterrestrial neutrinos.

    Search for Extraterrestrial Point Sources of Neutrinos with AMANDA-II2004In: Physical Review Letters, ISSN 0031-9007, E-ISSN 1079-7114, Vol. 92, no 7, p. 711021-711025Article in journal (Refereed)
    Abstract [en]

    The results of a search for point sources of high energy neutrinos in the northern hemisphere were presented using AMANDA-II data collected in the year 2000. The results included the flux limits on several active-galactic-nuclei blazars, microquasars, magnetars, and other candidate neutrino sources. A search for excesses above a random background of cosmic ray induced atmospheric neutrinos and misreconstructed downgoing cosmic-rays muons, which revealed no statistically significant neutrino point sources was also presented. It was shown that AMANDA-II had achieved the sensitivity required to probe known TeV γ-ray sources such as the blazar Markarian 501 in its 1997 flaring state at a level where neutrino and γ-ray fluxes were equal.

    Results from the Antarctic muon and nuetrino detector array2003In: Nuclear physics B, Proceedings supplements, ISSN 0920-5632, E-ISSN 1873-3832, Vol. 118, p. 371-379Article in journal (Refereed)
    Abstract [en]

    We show new results from both the older and newer incarnations of AMANDA (AMANDA-B10 and AMANDA-II, respectively). These results demonstrate that AMANDA is a functioning, multipurpose detector with significant physics and astrophysics reach. They include a new higher-statistics measurement of the atmospheric muon neutrino flux and preliminary results from searches for a variety of sources of ultrahigh energy neutrinos: generic point sources, gamma-ray bursters and diffuse sources producing muons in the detector, and diffuse sources producing electromagnetic or hadronic showers in or near the detector.

    Physics and operation of the AMANDA-II high energy neutrino telescope2002In: Proceedings of the SPIE - The International Society for Optical Engineering 2003, Institution of Electrical Engineers (IEE), 2002, p. 79-91Conference paper (Refereed)
    Abstract [en]

    This paper briefly describes the principle of operation and science goals of the AMANDA high energy neutrino telescope located at the South Pole, Antarctica. Results from an earlier phase of the telescope, called AMANDA-B10, demonstrate both reliable operation and the broad astrophysical reach of this device, which includes searches for a variety of sources of ultrahigh energy neutrinos: generic point sources, Gamma-Ray Bursts and diffuse sources. The predicted sensitivity and angular resolution of the telescope were confirmed by studies of atmospheric muon and neutrino backgrounds. We also report on the status of the analysis from AMANDA-II, a larger version with far greater capabilities. At this stage of analysis, details of the ice properties and other systematic uncertainties of the AMANDA-II telescope are under study, but we have made progress toward critical science objectives. In particular, we focus on the search for continuous emission from astrophysical point sources and the search for correlated neutrino emission from Gamma Ray Bursts detected by BATSE before decommissioning in May 2000. During the next two years, we expect to exploit the full potential of AMANDA-II with the installation of a new data acquisition system that records full waveforms from the in-ice optical sensors.

    Muon track reconstruction and data selection techniques in AMANDA2004In: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, ISSN 0168-9002, E-ISSN 1872-9576, Vol. 524, no 1-3, p. 169-194Article in journal (Refereed)
    Abstract [en]

    The Antarctic Muon And Neutrino Detector Array (AMANDA) is a high-energy neutrino telescope operating at the geographic South Pole. It is a lattice of photo-multiplier tubes buried deep in the polar ice between 1500 and 2000 m. The primary goal of this detector is to discover astrophysical sources of high-energy neutrinos. A high-energy muon neutrino coming through the earth from the Northern Hemisphere can be identified by the secondary muon moving upward through the detector. The muon tracks are reconstructed with a maximum likelihood method. It models the arrival times and amplitudes of Cherenkov photons registered by the photo-multipliers. This paper describes the different methods of reconstruction, which have been successfully implemented within AMANDA. Strategies for optimizing the reconstruction performance and rejecting background are presented. For a typical analysis procedure the direction of tracks are reconstructed with about 2° accuracy. © 2004 Elsevier B.V. All rights reserved.

    Abstract [en]

    This paper discusses a social and cognitive approach to the planning and implementation of knowledge support systems in a health care organization. A case study is presented and then discussed using a broad theoretical frame of reference gathered from the knowledge management field. The discussion is an illustration of the delicate trade-off between social and cognitive perspectives of a development project. The assumption is that these two aspects must be handled in an interconnected and balanced way. The aim of the paper is to illustrate the use of multiple perspectives as a tool for understanding how this problem can be dealt with.

    Abstract [en]

    Knowledge management, as an academic area, is maturing; however, there are still problems connected with both the diversity of the theoretical base and the gap between theory and its practical application. In this paper we tackle these problems by reviewing a number of basic knowledge management theories with the intention of formulating a more integrated and at the same time practical planning framework. The focus guiding the literature selection is on basic theories about the nature of knowledge management, theories that expose the complex nature of knowledge in organizations. We examine these theories and try to understand what could be perceived as the paradoxical nature of these theories. Here we understand a paradox as something seemingly self-contradictory though perhaps actually well-founded statement. We focus on four areas or themes: 1) knowledge as the key resource of a business, 2) knowledge as a competitive force and source of growth, 3) the nature of the management of a knowledge resource, and 4) the management of knowledge workers. From a practical point of view, the conflicting arguments of these theories can be seen as possible strategic options. Based on these discussions we then formulate a framework, or what might be called a strategic option generator. As a concluding discussion we focus on the contribution of IS/IT to the realization of the different possible strategic options. This is done on a rather general level, where we examine the possibilities of IS/IT in relation to the paradoxes.

    Knowledge triangle pedagogy: a global software development project connecting university-company-students2016In: Innovative technologies and didactics in teaching / [ed] Wladimir bodrow, Yury Rogozov, Berlin: Conference Print , 2016, p. 11-18Conference paper (Refereed)
    Abstract [en]

    This paper presents the experiences of setting up a knowledge triangle project in the software development field as an approach to teaching in the area of information systems and information technologies. The case includes an international dimension of the IT industry as it interconnects several countries. The cooperation between company and university is a pedagogical tool for creating an educational situation which conveys motivation and broad perspectives to the student. However, this brings in a number of problems and a generally higher level of complexity. This paper explores a case that illustrates the complexities and presents a generic model of a setup for a knowledge-triangle-based educational situation. Its model adopts an increasingly important aspect of IT education, namely how to prepare students for the globalized nature of the IT industry. The final discussion focuses on issues concerning the use of knowledge triangle thinking, including complexity, measurements, pedagogy and organization.

    Motivation for adopting fall prevention measures: a literature review searching for technology acceptance factors2018In: CENTERIS 2018 - International Conference on ENTERprise Information Systems / ProjMAN 2018 - International Conference on Project MANagement / HCist 2018 - International Conference on Health and Social Care Information Systems and Technologies / [ed] João Eduardo Quintela Varajão, Maria Manuela Cruz-Cunha, Ricardo Martinho, Rui Rijo, Dulce Domingos, Emanuel Peres, Nederland: Elsevier, 2018, Vol. 138, p. 3-11Conference paper (Refereed)
    Abstract [en]

    This paper presents a literature review of motivating factors for taking part in fall prevention activities among the elderly. The research aim is to improve the design and development of IT-based fall prevention programs for a deeper understanding of what motivates users to take part in such programs. Making fall prevention IT-based might improve the situation but might also become an obstacle in itself. To better ground this design process, a review is made of current efforts of fall prevention and of understanding motives for participation in fall prevention programs. As a result, we present a set of driving forces for the elderly to participate in fall prevention and discuss these in the context of technology acceptance theory, giving outlines for a model of motivating factors for them to use IT-based fall preventions systems. The results show a general direction of motivational efforts used in fall prevention to consist of some form of personalization strategy where, e.g., personal goals and conditions are used to adapt prevention measures to the individual.

    Taking Adaptable Co-design Action: Flexible Learning Between Health Experts, End-Users and Technology Experts in the Early Stage of eHealth Design2019In: eTELEMED 2019: The Eleventh International Conference on eHealth, Telemedicine, and Social Medicine / [ed] Yoshitoshi Murata and Oliver Heinze, International Academy, Research and Industry Association (IARIA), 2019, p. 90-95Conference paper (Refereed)
    Abstract [en]

    Co-design, as a way of integrating users’perspectives and technical possibilities, has been subject to amultitude of interpretations. To facilitate the development ofpatient-empowerment services, co-design is a central approachneeded to ensure high acceptance among users. In thisresearch, we offer a flexible co-design approach by building onadaptive and continuous planning based on sets of co-designactions directed towards participants’ mutual learning. Theresearch is based on the experiences of a co-design processwithin the area of eHealth, specifically the fall prevention area,as a special case of self-training systems and self-managementsystems. The project team comprises a variety of membergroups, including the elderly, technical developers, businessdevelopers, methods experts and project management. The keysuccess factor was identified among the persons of the differentgroups as achieving possibilities for learning. To make learningprocesses requires adaptability and flexibility in interactingdifferent planning actions in order to balance both the need fortechnology development and the understanding of users’needs.

    The Creation of Users: A Learning Experience in Information System Development2018In: International Journal of E-Health and Medical Communications (IJEHMC), ISSN 1947-315X, E-ISSN 1947-3168, Vol. 9, no 2, p. 74-88, article id 5Article in journal (Refereed)
    Abstract [en]

    The purpose of this article is to provide a better understanding of an information systems development process from a learning theory perspective. The authors wish to investigate how learning concepts can improve the practice of developing such systems. They look closer at the activities and outcomes of a development project with the focus on the user side and how these can be understood using different theories from the field of learning. The purpose of the case project was to ensure that the intended users of the systems (in this case, heart failure patients) should be able to influence the choices made during the project so that the implemented system would benefit the whole group of patients. During this process, it became apparent that the users themselves developed and changed a great deal. In this research, the authors therefore wish to investigate the learning and change mechanism that came into play through the designed participative ISD process. As a result, they suggest that a learning mechanism should be planned for in any ISD process, regardless of what methodology is applied.

    Abstract [en]

    The quest for user friendly systems that fit into an organizational reality and yet stay competitive on a very crowded marketplace is a challenge. This report covers the setup of an eHealth project that faces challenges in all these areas, not least in the intersections between them. We discuss these challenges in the context of a research and development project, FRONT-VL, which is in its start-up phase, giving samples of problems and opportunities. The purpose of the paper is to problematize eHealth development and to provide initial insight into the planning and conduct of such projects.

    Challenges for Heart Failure Patients’ Self-Care Systems: Analysis of Patients’ Needs2014In: Centeris 2014 - Conference on Enterprise Information Systems / Projman 2014 - International Conference on Project management / HCIST 2014 - International Conference on Health and Social Care Information Systems and Technologies / [ed] Varajao, J; Cunha, M; BjornAndersen, N; Turner, R; Wijesekera, D; Martinho, R; Rijo, R, Elsevier, 2014, Vol. 16, p. 1256-1264Conference paper (Refereed)
    Abstract [en]

    Self-care is important for heart failure patients. However, what are the views of patients on their situation when it comes to realizing self-care? The aim of the paper is to investigate the self-care needs of HF patients, by understanding the issues they embrace in their self-care processes. In this paper we make a review of 17 interviews and make a classification of what the needs are for possible information technology support systems. Based on the analysis of these interviews, we identify the diversity of needs in support of activities related to different background conditions and the dynamics of change of learning and changes in the heart failure condition. The contribution of the paper is a framework for understanding the diversity of needs and the specific situations of this group of patients.

    Understanding Heart Failure Care as a Patient Learning Process2013In: HCist'2013 - International Conference on Health and Social Care Information Systems and Technologies - leveraging health and social care through people, processes and information systems, to be held in Lisbon, Portugal, from 23 to 25 October, 2013., Elsevier, 2013, Vol. 9, p. 930-939Conference paper (Refereed)
    Abstract [en]

    The paper deals with the planning of eHealth systems in the area of chronic care from a patient-centred perspective. The particular area is heart failure (HF) and systems that support patients’ possibilities to be active learners during the care processes. A better understanding of this process is hoped to create a basis for the development of appropriate information systems or information technology (IS/IT) support of learning processes. The objective of this paper is the development of a better understanding of the challenges of chronic illness with special focus on HF. The results are presented as a planning framework that guides the choice and design of ICT-based support systems.

    User Involvement in the Co-design of Self-care Support Systems for Heart Failure Patients2015In: Conference on Enterprise Information Systems/International Conference on Project Management/Conference on Health and Social Care Information Systems and Technologies, CENTERIS/ProjMAN / HCist 2015, Elsevier, 2015, Vol. 64, p. 118-124Conference paper (Refereed)
    Abstract [en]

    In this paper the nature of user involvement in a co-design process will be explored. The outlines of a research project aiming at developing support systems for self-care inpatients suffering from chronic heart failure will be presented. The project is planned to perform a co-design effort where users (patients and healthcare professionals) will be given the opportunity to influence the development of support systems. We will discuss a number of possibilities and challenges that lie in the design of this kind of project and also some findings from its early stages. This report presents the experiences of users’ input, which are discussed in the context of previous research on benefits of user contributions in systems development.

    An Evaluation of a KM Diagnostic Instrument2007In: Proceedings of the 6th International Conference on Perspectives in Business Information Research - BIR'2007 / [ed] Nummenmaa, J., & Söderström, E., Tampere, Finland: Department of Computer Sciences, University of Tampere , 2007, p. 7-21Conference paper (Refereed)
    Abstract [en]

    Knowledge management is today an established approach to improve and renew organizations. The right use of information systems are often essential element in a successful KM strategy, however creating the right mix of KM activities and system is difficult and failures are frequent. Getting a good grip of the current situation and the special condition of the organization is therefore essential. In this paper we study an initiating questionnaire, taken from the KM literature, with a background in US management consulting industry. The aim of the paper is to evaluate the questionnaire, from a Swedish perspective. This is done with the aim to search for more general advice for anyone wanting to adapt and use such a questionnaire in their own situation. For this purpose, a number of applications of the questionnaire is presented and investigated. The outcome of the study is an initial assessment of the usefulness of the questionnaire and some recommendations for further use and research into the questionnaire. The usefulness seems to depend on the situation of persons that the questionnaire is given to. The analysis shows that the questionnaire seems to fit rather well to companies that were included in the study, especially on a management level. However, some possible problem areas were also discovered, the background, motivation and work situation of some personnel group could interfere with the effectiveness of the questionnaire.

    Effects of electron-electron interaction in pristine and doped graphene2014Independent thesis Advanced level (degree of Master (Two Years)), 30 credits / 45 HE creditsStudent thesis
    Abstract [en]

    The goal of this master thesis is to investigate the eect of electron-electron interaction on electronic properties of graphene that can be measured experimentally. A tight-binding model, which includes up to next-nearest-neighbor hopping, with parameters tted to density functional theory calculations, has been used to describe the electronic structure of graphene. The electron-electron interaction is described by the Hubbard model using a mean- eld approximation. Based on the analysis of dierent tight-binding models available in the literature, we conclude that a next-nearest-neighbor tight-binding model is in better agreement with density functional theory calculations, especially for the linear dispersion around the Dirac point. The Fermi velocity in this case is very close to the experimental value, which was measured by using a variety of techniques. Interaction-induced modi cations of the linear dispersion around the Dirac point have been obtained. Unlike the non-local Hartree-Fock calculations, which take into account the long-range electron-electron interaction and yield logarithmic corrections, in agreement with experiment, we found only linear modi cations of the Fermi velocity. The reasons why one cannot obtain logarithmic corrections using the mean- eld Hubbard model have been discussed in detail. The remaining part of the thesis is focused on calculations of the local density of states around a single substitutional impurity in graphene. This quantity can be directly compared to the results of the scanning tunneling microscopy in doped graphene. We compare explicitly non-interacting and interacting cases. In the latter case, we performed self-consistent calculations, and found that electron-electron interaction has a signi cant eect on the local density of states. Furthermore, the band gap at high-symmetry points of the Brillouin zone of a supercell, triggered by the impurity, is modi ed by interactions. We use a perturbative model to explain this eect and quantitative agreement with numerical results. In conclusion, it is expected that the long-range electron-electron nteraction is extremely strong and important in graphene. However, as this thesis has shown, interactions at the level of the Hubbard model and mean- eld approximation also introduce corrections to the electronic properties of graphene.

    Effects of short-range electron-electron interactions in doped graphene2015In: Physical Review B. Condensed Matter and Materials Physics, ISSN 1098-0121, E-ISSN 1550-235X, Vol. 92, no 15, article id 155420Article in journal (Refereed)
    Abstract [en]

    We study theoretically the effects of short-range electron-electron interactions on the electronic structure of graphene, in the presence of substitutional impurities. Our computational approach is based on the π orbital tight-binding model for graphene, with the electron-electron interactions treated self-consistently at the level of the mean-field Hubbard model. The finite impurity concentration is modeled using the supercell approach. We compare explicitly noninteracting and interacting cases with varying interaction strength and impurity potential strength. We focus in particular on the interaction-induced modifications in the local density of states around the impurity, which is a quantity that can be directly probed by scanning tunneling spectroscopy of doped graphene. We find that the resonant character of the impurity states near the Fermi level is enhanced by the interactions. Furthermore, the size of the energy gap, which opens up at high-symmetry points of the Brillouin zone of the supercell upon doping, is significantly affected by the interactions. The details of this effect depend subtly on the supercell geometry. We use a perturbative model to explain these features and find quantitative agreement with numerical results.

    That's Funny! The humorous effect of misappropriating disciplinary-specific semiotic resources2014In: The first Conference of the International Association for Cognitive Semiotics, Lund, Sweden, 25-27 Sept 2014, 2014, p. 50-51Conference paper (Refereed)
    Abstract [en]

    The socialization of disciplinary outsiders into an academic discipline has been described both in terms of becoming fluent in a disciplinary discourse (Airey, 2009; Airey & Linder, 2009; Northedge, 2002) and achieving disciplinary literacy (Airey, 2011, 2013; Geisler, 1994). In this paper we investigate disciplinary boundaries by documenting the responses of academics to a semiotic disciplinary hybrid. The hybrid we use is the Physikalisches Lied, a bogus piece of sheet music into which disciplinary-specific semiotic resources from the realm of physics have been incorporated to humorous effect.

    The piece is presented to three distinct disciplinary focus groups: physicists, musicians and a group of academics who have had little contact with either discipline. In order to elicit disciplinary responses that are free from researcher prompts, each focus group is first asked the simple, open-ended question What do you see here? Once discussion of this question is exhausted the focus groups are asked to identify as many puns as they can—essentially all the disciplinary items that they feel have been misappropriated—and to attempt to explain what this means from a disciplinary standpoint. The differences in the responses of the three groups are presented and analysed.

    We argue that semiotic material focused on by each of the three groups and the nature of the explanation offered, provide evidence of the degree of integration into the disciplines of physics and music. Our findings shed light on the process of becoming a disciplinary insider and the semiotic work involved in this process.

    What Knowledge Do Trainee Physics Teachers Need to Learn?: Differences in the Views of Training Staff2014In: International Science Education Conference ISEC 2014, National Institute of Education, Singapore, 25-27 November, 2014, Singapore: Ministry of Education, National Institute of Education , 2014, p. 62-Conference paper (Refereed)
    Abstract [en]

    Although the impact of disciplinary differences on teaching and learning has been extensively discussed in the literature (e.g. Becher 1989; Becher and Trowler 2001; Lindblom-Ylännea et al. 2006; Neumann 2001; Neumann and Becher 2002), little research has explored this issue in relation to teacher training. In particular, we know of no work that examines differing views about the knowledge that trainee teachers need to learn across different settings. In this paper we analyse differences in the expressed views of staff involved in the training of prospective physics teachers in three environments: the education department, the physics department and schools. We analyse these differences in terms of two constructs: disciplinary literacy goals (Airey 2011, 2013) and disciplinary knowledge structures (Bernstein 1999).

    In terms of disciplinary literacy we find a stronger emphasis on learning goals for the academy expressed by informants from the physics and education departments. This can be contrasted with the view that the needs of the workplace are paramount expressed by school practitioners.

    Then, using Bernstein’s knowledge structures, we also identify clear differences in views about the nature of knowledge itself with a more hierarchical view of knowledge prevalent in the physics department and the more horizontal view of knowledge prevalent in the education department.

    The study highlights the often-conflicting signals about what constitutes useful knowledge that prospective physics teachers need to negotiate during their training. We tentatively suggest that more attention should be paid to both the theory/practice divide and potential epistemological differences in the training of prospective teachers.

    Social semiotics in university physics education: Leveraging critical constellations of disciplinary representations2015In: Science Education Research: Engaging learners for a sustainable future / [ed] Jari Lavonen, Kalle Juuti, Jarkko Lampiselkä, Anna Uitto, Kaisa Hahl, European Science Education Research Association , 2015Conference paper (Refereed)
    Abstract [en]

    Social semiotics is a broad construct where all communication is viewed as being realized through signs and their signification. In physics education we usually refer to these signs as disciplinary representations. These disciplinary representations are the semiotic resources used in physics communication, such as written and oral languages, diagrams, graphs, mathematics, apparatus and simulations. This alternative depiction of representations is used to build theory with respect to the construction and sharing of disciplinary knowledge in the teaching and learning of university physics. Based on empirical studies of physics students cooperating to explain the refraction of light, a number of theoretical constructs were developed. In this presentation we describe these constructs and examine their usefulness for problematizing teaching and learning in university physics. The theoretical constructs are: fluency in semiotic resources, disciplinary affordance and critical constellations.

    The conclusion formulates a proposal that has these constructs provide university physics teachers with a new set of meaningfully and practical tools, which will enable them to re-conceptualize their practice in ways that have the distinct potential to optimally enhance student learning.

    A Semiotic Analysis of the Disciplinary Affordances of the Hertzsprung-Russell Diagram in Astronomy2014In: The 5th International 360 Conference, Encompassing the multimodality of knowledge, May 8-10 2014, Aarhus University, Denmark, Aarhus: Aarhus University , 2014, p. 22-Conference paper (Refereed)
    Abstract [en]

    One of the central characteristics of disciplines is that they create their own particular ways of knowing the world through their discourse (Airey & Linder 2009). This process is facilitated by the specialization and refinement of disciplinary-specific semiotic resources over time. Nowhere is this truer than in the sciences, where it is the norm that disciplinary-specific representations have been introduced and then refined by a number of different actors (Airey 2009). As a consequence, many of the semiotic resources used in the sciences today still retain some traces of their historical roots. This makes the aquisition of disciplinary literacy (Airey, 2013) particularly problematic (see Eriksson et al. 2014 for an example from astronomy).

     In this paper we analyse one such disciplinary-specific semiotic resource from the field of Astronomy—the Hertzsprung-Russell diagram. We audit the potential of this semiotic resource to provide access to disciplinary knowledge—what Fredlund et al (2012) have termed its disciplinary affordances. Our analysis includes consideration of the use of scales, labels, symbols, sizes and colour. We show how, for historical reasons, the use of these aspects in the resource may differ from what might be expected by a newcomer to the discipline.

    We suggest that some of the issues we highlight in our analysis may, in fact, be contributors to alternative conceptions and therefore propose that lecturers pay particular attention to the disambiguation of these features for their students.

    Piratkopiering - en oändlig historia?2006Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Abstract (English)

    Background: Illegal copying increases rapidly. Software-, game- and music industry are experiencing troubled times at the moment. Today, a practically ignorant person would have no problems to get hold of a newly published record before it reaches the stores because of the

    illegal copying. This problem is made possible due to that no good solution exists. Copy protection isn’t good enough and peer-to-peer-networks are bigger than ever. In this work we will examine specifically the music industry.

    Purpose: We will specialize in the term of illegal copying. Further we want to enlight and inform the music industry as well as the users of the problem and it´s future. We hope the result we will achieve can be a foundation for further research.

    Realization: We have gathered our information from articles on the Internet and also from updated literature. Interviews were made over the phone with Magnus Mårtensson, IFPI (International Federation of the Phonographic Industry), Anna Burén, lawyer of copyright at

    Swedish Radio, Per Sandin, General manager EMI marketing and also a lot of Internetsuppliers. We have also compilated an inquiry which has been replied to by many people.

    Conclusion: Many of the buyers from the past consider the cost of a CD far too high. Instead they have discovered the illegal copying and its unlimited functions. They have also realized how easy you can get new music without reprisals, which mostly depends on the vague and

    not to scary laws. Music companies are losing money and therefore they raise the prize of a single CD, simultaneously as they work to find the perfect copy protection. The future looks uncertain and for the moment, those who are copying along with peer-to-peer-networks have

    all the trumps.

    Keywords: mp3, CD, copy-protection, peer-to-peer-networks, copyright, illegal copying, music companies.

    Time performance comparison in determining the weak parts in wooden logs2009Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The steadily increasing demand of wood forces sawmills to increase the efficiency and effectiveness of their equipments. The weak parts and the twist in wooden logs have been documented as the most common and crucial defect in sawn lumber.

    In this thesis we are going to implement a program which is able to determine the weak parts in wooden logs. The implementation will be in two languages C++ and Matlab. Parts of the program are going to be implemented sometimes by C++ and sometimes by Matlab therefore different designs are going to be tested. The aim of this thesis is to check whether these designs will meet the real time bound of 10 m/s.

    The result shows that there is a huge difference in time performance for the different designs. Therefore, different discretization levels were used in order to meet the deadline of 10m/s. We found that in order to get better speed one should calculate the matrix for the function F and the Jacobian function J by using C++ not by Matlab. Also we found that when we called functions from one language to another an extra time is added.

    User Adoption of Big Data Analyticsin the Public Sector2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The goal of this thesis was to investigate the factors that influence the adoption of big data analytics by public sector employees based on the adapted Unified Theory of Acceptance and Use of Technology (UTAUT) model. A mixed method of survey and interviews were used to collect data from employees of a Canadian provincial government ministry. The results show that performance expectancy and facilitating conditions have significant positive effects on the adoption intention of big data analytics, while effort expectancy has a significant negative effect on the adoption intention of big data analytics. The result shows that social influence does not have a significant effect on adoption intention. In terms of moderating variables, the results show that gender moderates the effects of effort expectancy, social influence and facilitating condition; data experience moderates the effects of performance expectancy, effort expectancy and facilitating condition; and leadership moderates the effect of social influence. The moderation effects of age on performance expectancy, effort expectancy is significant for only employees in the 40 to 49 age group while the moderation effects of age on social influence is significant for employees that are 40 years and more. Based on the results, implications for public sector organizations planning to implement big data analytics were discussed and suggestions for further research were made. This research contributes to existing studies on the user adoption of big data analytics.

    Honeypots in network security2010Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Day by day, more and more people are using internet all over the world. It is becoming apart of everyone’s life. People are checking their e-mails, surfing over internet, purchasinggoods, playing online games, paying bills on the internet etc. However, while performingall these things, how many people know about security? Do they know the risk of beingattacked, infecting by malicious software? Even some of the malicious software arespreading over network to create more threats by users. How many users are aware of thattheir computer may be used as zombie computers to target other victim systems? Astechnology is growing rapidly, newer attacks are appearing. Security is a key point to getover all these problems. In this thesis, we will make a real life scenario, using honeypots.Honeypot is a well designed system that attracts hackers into it. By luring the hackerinto the system, it is possible to monitor the processes that are started and running on thesystem by hacker. In other words, honeypot is a trap machine which looks like a realsystem in order to attract the attacker. The aim of the honeypot is analyzing, understanding,watching and tracking hacker’s behaviours in order to create more secure systems.Honeypot is great way to improve network security administrators’ knowledge and learnhow to get information from a victim system using forensic tools. Honeypot is also veryuseful for future threats to keep track of new technology attacks.
