    Double Blinding-Attack on Entanglement-Based Quantum Key Distribution Protocols2012In: AIP Conference Proceedings, ISSN 0094-243X, E-ISSN 1551-7616, Vol. 1424, no 1, p. 9-16Article in journal (Refereed)
    Abstract [en]

    We propose a double blinding-attack on entangled-based quantum key distribution protocols. The principle of the attack is the same as in existing blinding attack except that instead of blinding the detectors on one side only, Eve is blinding the detectors of both Alice and Bob. In the BBM92 protocol, the attack allows Eve to get a full knowledge of the key and remain undetected even if Alice and Bob are using 100% efficient detectors. The attack can be easily extended to Ekert protocol, with an efficiency as high as 85.3%.

    Multiple-photon absorption attack on entanglement-based quantum key distribution protocols2013In: Quantum Bio-Informatics V: Proceedings of the Quantum Bio-Informatics 2011 : Tokyo University of Science, Japan, 7 – 12 March 2011 / [ed] Luigi Accardi, Wolfgang Freudenberg, Masanori Ohya, Singapore: World Scientific, 2013, vol. 30, p. 171-180Conference paper (Refereed)
    Abstract [en]

    We propose a multiple-photon absorption attack on Quantum Key Distribution protocols. In this attack, the eavesdropper (Eve) is in control of the source and sends pulses correlated in polarization (but not entangled) containing several photons at frequencies for which only multiple-photon absorptions are possible in Alice's and Bob's detectors. Whenever the number of photons from one pulse are dispatched in insufficient number to trigger a multiple-photon absorption in either channel, the pulse remains undetected. We show that this simple feature is enough to reproduce the type of statistics on the detected pulses that are considered as indicating a secure quantum key distribution in entangled-based protocols, even though the source is controlled by Eve, and we discuss possible countermeasures.

    Investigations on baryonium and other rare pmacrp annihilation modes using high resolution pi0 spectrometers (PS 182)1985In: Antiproton 1984. Proceedings of the VII European Symposium on Antiproton Interactions, Institution of Electrical Engineers (IEE), 1985, p. 297-304Conference paper (Refereed)
    Abstract [en]

    In the search for heavy, narrow exotic states such as baryonium or glueballs, carried out so far, various methods of high- and low-energy production, low-energy formation, and e+e- reactions were used. In particular, a search for baryonium states below threshold (mxlsimmppmacr) has shown some evidence [Richter et al., 1983, Brando et al., 1984] for a few states. However, the results of these measurements suffer from poor statistics. Among the possible methods which can be applied in the baryonium bound state research at LEAR, the authors consider the study of the reaction ppmacrrarrX+pi0 as the most promising. They have performed an experiment to study this reaction by means of an experimental set-up especially tailored for measuring monoenergetic pi0,s, allowing for both angular distribution measurements and high-resolution spectroscopy. They report on the preliminary results from our actual measurements of the inclusive pi0 and eta spectra following the antiproton annihilation at rest.

    A π0 and η spectrometer of lead glass and BGO for momenta up to 1 GeV/c1986In: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, ISSN 0168-9002, E-ISSN 1872-9576, Vol. 244, no 3, p. 380-390Article in journal (Refereed)
    Abstract [en]

    A spectrometer consisting of two sets of bismuth germanium oxide (BGO) crystals and a lead-glass array has been used to measure the π0 and η momentum spectra produced from proton-antiproton annihilations at rest. We describe the test of the BGO sets in electron beams of energies from 50 to 450 MeV. We discuss the method of construction and calibration of the lead-glass array, as well as procedures to extract the energy and position resolutions for detected photons. A momentum resolution (σ) for π0's and η's of 4% and 3%, respectively has been achieved at momenta below 1 GeV/c. © 1986.

    Experimental study of the inclusive η-spectrum from p {Mathematical expression} annihilations at rest in liquid hydrogen1989In: Zeitschrift für Physik C Particles and Fields, ISSN 0170-9739, E-ISSN 1431-5858, Vol. 42, no 1, p. 49-58Article in journal (Refereed)
    Abstract [en]

    The inclusive η-momentum spectrum from {Mathematical expression} annihilations at rest in liquid hydrogen was measured at LEAR. Branching ratios were obtained for {Mathematical expression}, and ηη(8.1±3.1)×10 -5. An upper limit for {Mathematical expression} of 1.8×10 -4 at 95% CL was found. The ratio of the branching ratios is BR(ηρ{variant})/BR(ηω)=0.51 -0.06 +0.20. For the ratio of branching ratios into two pseudoscalar mesons, we have BR(ηπ 0)/BR(π 0π 0)=0.65±0.14, BR(ηη)/BR(π 0π 0), BR(ηη ′)/BR(π 0π 0) at 95% CL, and BR(ηη)/BR(ηπ 0). © 1989 Springer-Verlag.

    Är det säkert att byta från originalläkemedlet för inflixmab, Remicade®, till CT-P13 och är CT-P13 ekvivalent med Remicade® med avseende på effekt, säkerhet, immunogenicitet och farmakokinetik?2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Biologic drugs are effective against numerous diseases but they are very expensive. The European Medicines Agency approved sales of biosimilars in 2006. Biosimilars are copies of already approved biologic drugs, but they are not considered to be exact copies like generic drugs are. Only living organisms can produce substances with the complexity of biologic drugs. Differences in pH, enviroment, and the purification process during the production of biologic drugs can affect the structure of the final product. Differences in the production processes can affect properties like the glycosylation pattern of the molecules which in turn can influence the effect of the drug. This is the reason biosimilars are not considered as exact copies of the original drug. The patent for Remicade® a TNF inhibitor expired in 2015 which led to the introduction of the first biosimilar for monoclonal antibodies (CT-P13) on the European market. The aim of this study was to investigate the efficacy, safety profile, immunogenicity and pharmacokinetics equivalence between CT-P13 and the original drug for infliximab, Remicade®. And to investigate if it was safe to switch from Remicade to CT-P13.

     

    The articles for the study were collected from PubMed, a medical and bioscientific database, and five studies were chosen for further analysis. The articles were not limited to a specific indication for infliximab, so the studies included patients with rhematoid arthritis (RA), ankylosing spondylitis (AS) and inflammatory bowel disease (IBD). The short-term equivalence between Remicade® and CT-P13 was analysed in the studies but more studies including long-term equivalence are needed. Based on the primary endpoints in the studies it seems to be safe to switch from Remicade® to CT-P13 and short-term equivalence seems to exist between CT-P13 and Remicade® considering the efficacy, safety profile, immunogenicity and pharmacokinetics equivalence in patients with RA, AS and IBD.

    Sustainable Development in Swedish Municipalities: To know, to be able, to want and to do2001Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    A process of change like the building-up of sustainable societies can be visualised as four steps: to know, to be able, to want and to do. To pay attention to the appropriate measures and the best solutions implies a wide range of knowledge of natural and societal conditions. But to make it possible to realize them, there has to be space of action including physical tools (technique, money etc.), as well as desire and courage among the participants and decision-makers to act towards sustainability. The most important prerequisites for sustainable development are considered to be appropriate natural resources management and public participation. In this thesis I concentrate on the possibilities of modifying administration at local levels in order to economise resources in durable ways, locally as well as globally. In some case studies I examine to what extent local Agenda 21 (LA21) processes can facilitate this realization.

    In developing more sustainable societies I emphasise the following aspects to be among the most relevant: Society has to prepare for unexpected outcomes, thus the apparent unpredictability of the behaviour of ecosystems and their response to impacts have to be taken into account in planning and in making decisions. Moreover, it has to be discussed what to do if aims are reached without obtaining the expected recovery in the ecosystems and in the natural situation. Environmental space and function should more often be used as a basis when managing natural resource. Finally, the interplay beween the central and the local levels should be enhanced in order to choose the most relevant measures and to strive in the same direction: towards creating more flexible societies.

    The LA21 processes can very well be excellent tools in this work because they provide platforms for better understanding and exchange of knowledge and experience among different levels of society. These discussions can make the participants more willing to take actions as well as to find new solutions and new ways acting.

    The case studies show that the first steps towards more sustainable societies are taken. The support for LA21 given by the local governments has been and is absolutely vital to the progress and results of the processes. The most progressive results are found in the municipalities of the case study where top-level politicians have been most interested and have taken on the responsibility of LA21. My main conclusions of how the LA21 processes and the striving towards sustainability could be improved are that goals and visions should be discussed more thoroughly involving many parts of society. More and more these visions and objectives should observe the connections between environmental, economic and social issues. Furthermore, measures and actions should be diversified and flexible, and co-operation across administrative borders should be developed. It is also essential to formulate strategies of how to deal with up-coming ideas and proposals as well as how to increase the level of influence of all participants. In order to improve the handling of natural resources the kind of resource and the functions making it one has to be identified. To choose the most appropriate measures it is important to know if the resource is vital and scarce, scarce, or poisonous and/or if its use may cause pollution.

    Paper I comprises the frame of and the tools for developing the local system in Sweden in the direction of global sustainability. Swedish municipalities have taken the first steps towards sustainability mainly through local Agenda 21 processes. Environmental issues have a prominent role in the decision-making of the local governments, but social and economic topics are not connected to decisions on sustainable development to the same extent. How to proceed at the local level is discussed in this paper as is the national frame and local prerequisities for achieving sustainable development. This article states that most important factors, when creating sustainable societies, are active, high-level politicians and officials, a structured process with co-operation aiming at including all stakeholders' real influence, increased knowledge among all participants, positive thinking, feedback and information, money and much time. To use limited projects as one of the first steps of a more comprehensive process may attract more inhabitants to take part. Their results can be shown quite rapidly, further encouraging actions and involvement in other areas of interest.

    The papers II and III are based on a five-year study of the LA21 processes in four Swedish municipalities. In Paper II the LA21 of two of the chosen municipalities are analysed. Comparisons between attitudes among local politicians and officials and LA21 documents and projects indicate that the most important issues, to protect clean air and to co-operate with the inhabitants in LA21, are followed up in plans, actions and projects connected to LA21. The local governments have made efforts to improve the natural resources management, to prolong the views of planning in the local government, but they have difficulties in interpreting visions and long-term goals in their daily decisions. It is still too early to discern whether or not the two municipalities have moved towards sustainability.

    Paper III includes results from all four municipalities. This study shows that the LA21 processes have aroused many new thoughts, brought fields together and introduced new subjects into the municipal world. In the decisions of the local govemments' environmental considerations are treated seriously. There are signs of an increased dialogue and of public influence, especially within fields where the inhabitants are users. It is indicated that LA21 does not seem to have great influence on which natural resources are dealt with, but on how. New stakeholders within and outside the municipal organization have been identified through the LA21 processes, and more comprehensive ways of solving problems and a positive climate of testing new ideas have been created. In these respects LA21 has been and will be a significant support to the development of appropriate natural resources management at the local level.

    In Paper IV a part of a local Agenda 21 project aiming at reducing the nutrient supply into a Swedish Baltic Sea fjord is analysed. The reduction is to be carried out in way that permits and facilitates the re-use of the nutrients as fertilizers. This article is focused on how to implement the project and on how to increase public participation, especially that of farmers and owners of houses of single sewage treatment systems. Increased public participation needs continuous efforts by the project leaders. Indivdual as well as group actions, forming of small groups, information, feedback and continous encouragement are crucial. The homogenous group of farmers considers the management of natural resources very important. They have voluntarily formed five watercourse groups where community management is developed. The owners of houses of single sewage treatment systems form a heterogeneous group. They are mostly interested in individual measures. Constant changes of the prerequisites of sewage systems and lack of knowledge are other obstacles against carrying out voluntary measure.

    Kommunal verksamhetsprocess efter införandet av en e-tjänst: Informationsflöde och informationshantering sett ur ett Lean-perspektiv2011Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Trots de svenska medborgarnas ökande krav på digital självservice via e-tjänster, går införande trögt hos kommunerna. En anledning är den relativt låga kunskap som finns i området. Främst vad gäller avancerade e-tjänster som förutom att öka medborgarnas tillgänglighet, insyn och delaktighet i sina offentliga ärenden, även ska minska den administrativa hanteringen för att istället låta mer av resurserna gå till kärnverksamheten. I den här kvalitativa fallstudien studerades hur en kommunal verksamhetsprocess utvecklas vid införandet av en e-tjänst. Hur slöseri kan identifieras i processen informationshantering och informationsflöde och hur dessa förändrats efter att e-tjänsten införts. Resultatet baserades på material från intervjuer och analyserades utifrån Leans kategorier av slöseri och teorin om Microsystem. Resultatet visade att slöseri som uppstår i informationshantering och informationsflöde mellan enheter eller microsystem kunde identifieras om alla microsystem kartlägger processen tillsammans. Mycket slöseri hade tagits bort i utvecklingsarbetet och lett till en smidigare och troligtvis mer effektiv process. Ett antagande men som även bekräftades av personalens upplevelser från testförsöken. Processutvecklingen tillsammans med e-tjänsten har säkerställt delar av processflödet där antalet informationsöverföringar blivit färre och på så sätt troligtvis även minskat risken för att missförstånd och felhantering ska uppstå av informationshanteringen.

    Complement Component C3 and Butyrylcholinesterase Activity Are Associated with Neurodegeneration and Clinical Disability in Multiple Sclerosis2015In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 10, no 4, article id e0122048Article in journal (Refereed)
    Abstract [en]

    Dysregulation of the complement system is evident in many CNS diseases but mechanisms regulating complement activation in the CNS remain unclear. In a recent large rat genomewide expression profiling and linkage analysis we found co-regulation of complement C3 immediately downstream of butyrylcholinesterase (BuChE), an enzyme hydrolyzing acetylcholine (ACh), a classical neurotransmitter with immunoregulatory effects. We here determined levels of neurofilament-light (NFL), a marker for ongoing nerve injury, C3 and activity of the two main ACh hydrolyzing enzymes, acetylcholinesterase (AChE) and BuChE, in cerebrospinal fluid (CSF) from patients with MS (n = 48) and non-inflammatory controls (n = 18). C3 levels were elevated in MS patients compared to controls and correlated both to disability and NFL. C3 levels were not induced by relapses, but were increased in patients with >= 9 cerebral lesions on magnetic resonance imaging and in patients with progressive disease. BuChE activity did not differ at the group level, but was correlated to both C3 and NFL levels in individual samples. In conclusion, we show that CSF C3 correlates both to a marker for ongoing nerve injury and degree of disease disability. Moreover, our results also suggest a potential link between intrathecal cholinergic activity and complement activation. These results motivate further efforts directed at elucidating the regulation and effector functions of the complement system in MS, and its relation to cholinergic tone.

    Information and Communication Technologies in Support of Remembering: A Postphenomenological Study2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis aimed to study the everyday use of ICT-enabled memory aids in order to understand and to describe the technological mediations that are brought by them (i.e. how they shape/mediate experiences and actions of their users). To do this, a post-phenomenological approach was appropriated. Postphenomenology is a modified, hybrid phenomenology that tries to overcome the limitations of phenomenology. As for theoretical framework, ‘Technological Mediation’ was adopted to conduct the study. Technological Mediation as a theory provides concepts suitable for explorations of the phenomenon of human-technology relation.

    It was believed that this specific choice of approach and theoretical framework would provide a new way of exploring the use of concrete technologies in everyday life of human beings and the implications that this use might have on humans’ lives. The study was conducted in the city of Växjö, Sweden. Data was collected by conducting twelve face-to-face semi-structured interviews. Collected data was, then, analyzed by applying the concepts within the theoretical framework – Technological Mediation - to them.

    The results of this study provided a list of ICT-enabled devices and services that participants were using in their everyday life in order to support their memory such as: calendars, alarms, notes, bookmarks, etc. Furthermore, this study resulted in a detailed description of how these devices and services shaped/mediated the experiences and the actions of their users.

    Att fånga en oskuld: En undersökning kring ungdomars intresse för ekonomisk information online2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Att vid 18 års ålder tvingas ansvara för sina handlingar är för många ett stort steg, inte minst då en del av ansvaret är ekonomi. Ungdomarna vänder sig ofta till föräldrarna med frågor, men var ska de vända sig när föräldrarna inte har svaret? Bankerna har börjat söka sig lägre ner i åldrarna med sin marknadsföring för att fånga kunden innan denne blir myndig, men fortfarande är det många frågetecken kring informationen ungdomarna behöver.

    Uppdraget var att undersöka vad ungdomar behöver för information i en webbplats riktad mot ungdomar från banken. En undersökning genomfördes med en enkätundersökning med 100respondenter och tre olika fokusgrupper som genererade att ungdomarna känner att banker är alldeles för avlägsna. En minskad distans skulle medföra att ungdomarna lättare vänder sig till banken vid frågor kring sin ekonomi vilket i sin tur medför att deras intresse kring privatekonomiska frågor ökar.

    Designförslaget som presenteras fokuserar mycket på en funktion med textbaserad personlig service med co-browsingfunktioner som tillåter en bankman guida den unga kunden genom webbplatsen. Strävan är att ungdomarna ska känna en samhörighet till banken och lättare kan få alla typer av frågor besvarade då de var osäkra på vilken information de behöver. Om man inför en sådan tjänst bör användbarhetstest och utvärderingar på designförslaget genomföras för att kontrollera om distansen mellan bank och ungdom minskar.

    Effect of Antibacterial Mouthwash on Basal Metabolic Rate in Humans: A Randomized, Double-blinded, Cross-over Study2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The use of mouthwash is a common complement to oral care. However, the physiological implication of this use, besides of effects on oral hygiene, is poorly known. The research of the gut micro flora and its implications on the host is a very active area of research today. Many important connections between the gut micro flora and obesity and diabetes have been found. These billions of bacteria are part of the immune system, they produce essential vitamins and they make inaccessible polysaccharides more digestible to the host, just to mention a few of their symbiotic roles for the host.

    A less explored area is the micro flora in the oral cavity. On the back of the tongue, anaerobic bacteria can reduce dietary nitrate to nitrite which then further can be reduced to nitric oxide, NO. NO is important in several important biological functions, e.g. as a signal substance, vasoregulation, mucus production and antibacterial effects. Vegetables as beetroot and spinach are dietary sources with a high nitrate content. Also drinking water and processed meats can be of relevance. Nitrite is added to processed meat for the prevention of botulism but also adds taste and color.  

    Experiments on humans indicate that mitochondrial efficiency increases after nitrate load, manifested as a decreased oxygen demand during physical exercise. This can also be relevant under conditions where the mitochondrial function is impaired, such as in diabetes and cardiovascular diseases.

    First a pilot study was made to evaluate the nitrate reducing effect from the antibacterial mouthwash. The mouthwash proved very effective. The concentrations of nitrate and nitrite in saliva was analyzed by HPLC and saliva from the antibacterial treatment showed greatly reduced concentrations of nitrite and high concentrations of nitrate. Saliva from placebo mouthwash showed high concentrations of nitrite and low concentrations of nitrate as expected.

    To study the importance of oral bacteria on metabolism, we performed a randomized, cross-over double-blinded study with 19 healthy males between 22-43 years. During two separate three-day periods they used an antibacterial and placebo mouthwash, respectively. On the fourth day their basal metabolic rate (BMR) was measured with an indirect calorimetric system. Moreover, samples from saliva, urine and blood were collected but these results are not included in this thesis. An earlier, unpublished study has demonstrated that nitrate administration reduces the basal metabolic rate. Accordingly, our aim was to study potential effects on the basal metabolic rate following reduction of the number of oral bacteria by aid of antibacterial mouthwash. Our hypothesis was that the reduced availability of nitrite would decrease the availability of NO in the body and manifest as an increased basal metabolic rate.

    The results from indirect calorimetry measurements showed no significant difference between placebo and antibacterial mouthwash, but there may be confounding factors. Further study is needed to assess the potential effects on host metabolism by these bacteria.

    Studies of a full-scale mechanical prototype line for the ANTARES neutrino telescope and tests of a prototype instrument for deep-sea acoustic measurements2007In: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, ISSN 0168-9002, E-ISSN 1872-9576, Vol. 581, no 3, p. 695-708Article in journal (Refereed)
    Abstract [en]

    full-scale mechanical prototype line was deployed to a depth of 2500 m to test the leak tightness of the electronics containers and the pressure-resistant properties of an electromechanical cable under evaluation for use in the ANTARES deep-sea neutrino telescope. During a month-long immersion study, line parameter data were taken using miniature autonomous data loggers and shore-based optical time domain reflectometry. Details of the mechanical prototype line, the electromechanical cable and data acquisition are presented. Data taken during the immersion study revealed deficiencies in the pressure resistance of the electromechanical cable terminations at the entry points to the electronics containers. The improvements to the termination, which have been integrated into subsequent detection lines, are discussed. The line also allowed deep-sea acoustic measurements with a prototype hydrophone system. The technical setup of this system is described, and the first results of the data analysis are presented.

    The ANTARES optical beacon system2007In: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, ISSN 0168-9002, E-ISSN 1872-9576, Vol. 578, no 3, p. 498-509Article in journal (Refereed)
    Abstract [en]

    ANTARES is a neutrino telescope being deployed in the Mediterranean Sea. It consists of a three-dimensional array of photomultiplier tubes that can detect the Cherenkov light induced by charged particles produced in the interactions of neutrinos with the surrounding medium. High angular resolution can be achieved, in particular, when a muon is produced, provided that the Cherenkov photons are detected with sufficient timing precision. Considerations of the intrinsic time uncertainties stemming from the transit time spread in the photomultiplier tubes and the mechanism of transmission of light in sea water lead to the conclusion that a relative time accuracy of the order of 0.5 ns is desirable. Accordingly, different time calibration systems have been developed for the ANTARES telescope. In this article, a system based on Optical Beacons, a set of external and well-controlled pulsed light sources located throughout the detector, is described. This calibration system takes into account the optical properties of sea water, which is used as the detection volume of the ANTARES telescope. The design, tests, construction and first results of the two types of beacons, LED and laser-based, are presented. (C) 2007 Elsevier B.V. All rights reserved.

    Performance of the first ANTARES detector line2009In: Astroparticle physics, ISSN 0927-6505, E-ISSN 1873-2852, Vol. 31, no 4, p. 277-283Article in journal (Refereed)
    Abstract [en]

    In this paper we report on the data recorded with the first Antares detector line. The line was deployed on the 14th of February 2006 and was connected to the readout 2 weeks later. Environmental data for one and a half years of running are shown. Measurements of atmospheric muons from data taken from selected runs during the first 6 months of operation are presented. Performance figures in terms of time residuals and angular resolution are given. Finally the angular distribution of atmospheric muons is presented and from this the depth profile of the muon intensity is derived. (C) 2009 Elsevier B.V. All rights reserved.

    Extremal dependency:The GARCH(1,1) model and an Agent based model2013Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis focuses on stochastic processes and some of their properties are investigated which are necessary to determine the tools, the extremal index and the extremogram. Both mathematical tools measure extremal dependency within random time series. Two different models are introduced and related properties are discussed. The probability function of the Agent based model is surveyed explicitly and strong stationarity is proven. Data sets for both processes are simulated and clustering of the data is investigated with two different methods. Finally an estimation of the extremogram is used to interpret dependency of extremes within the data.

    Random Stream Cipher2007Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Stream ciphers are counted as an important part of symmetric encryption method. Their basic idea comes from One-Time-Pad cipher using XOR operator on the plain text and the key to generate the cipher. The present work brings a new idea in symmetric encryption method, which inherits stream key generation idea from synchronous stream cipher and uses division instead of xoring. The Usage of division to combine the plain text with stream key gives numerous abilities to this method that the most important one is using random factors to produce the ciphers.

    ICTs use in the public Greek Primary Schools: the teachers' experiences2017Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    Education is a sector that has the potential to become a critical area of action for the full exploitation of ICT. Educational systems of developed and developing countries have an ever-increasing tendency to apply ICT to education, in an attempt to prepare their students for the future's society. This thesis attempted to explore what kind of ICT is used in the Greek Primary Schools and develop an understanding on the relationship between the ICT and the teachers. The philosophical background is post-phenomenology and the methods chosen for collecting data for this research are policy document analysis and interviews. The empirical findings show that various ICT are being used in the classrooms of the Greek Primary Schools,  others widely and others occasionally. The research compares the legal framework revolving around ICT in Primary Schools in Greece, with the teachers' own experiences and shows that the guidelines suggested by the Greek Ministry of Education cannot be followed easily, due to economical and pedagogical reasons. It also investigates the ICT's effects on the teachers and the students through the teachers' own words and perceptions. The effects are mostly positive, there are mentioned however, some negative ones to take into consideration. Finally, the research presents a number of sectors where the participant teachers suggested there is room for improvement. By comparing the legal framework with the situation in the Primary Schools, this research adds a new perspective to the previous literature. The findings show that the current situation can be improved and the teachers' statements may trigger further research.

    Digital Wall: The University’s learning and information space2017Student paper other, 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A North American university is engaged in a large transformation project involving the wholeorganisation. Students, Lecturers, departments and additional questions from the shared leadership team are engaging in defining the services offered, in particular from the university library and its associated sub-services. It is an exciting time for the University as it seeks to not only define its services but also how these can be created and consumed.There are many aspects to this re-organisation and many items to be addressed. In this report,we look at the current situation at the University, as well as taking into account the aspirations of the stakeholders. We start by drawing out a Rich Picture, part of Soft System Methodology (SSM) (Checkland, 1981) which we use in order to spot opportunities that are available for further exploration. Much of the information that we use comes from material supplied by the University itself as well as interviews with the Head of Library services and Head of Library IT. We look indepth at how SSM assists in this process of evaluation through its focus on participation and how it may assist us to understand the many different perspectives collected in our research. SSM consequently assists in defining problems with solutions to any areas that have drawn our attention. Following the evaluation of collected data, discussions and our own observations, we identify that a digital wall that is being proposed for the redesigned library presents an opportunity to explore possibilities for exploitation of this technology. Further research on other digital walls such as Brisbane’s Cube (Abdi et al, 2014), and Auraria Library’s Discovery Wall(Burch, 2016) shows some of the uses that these walls have been put to and how the Institutions use them. We then use a number of models to evaluate the data that we collected on digital walls and from the North American University and analyse it in order to inform our thinking. These models can be used independently or collectively to evaluate data from different perspectives. As such we were able to look at problems and solutions from the perspective of many of the actors involved in shaping the future library services. These models and results are discussed in the report. Finally, we take our results and make a number of proposals for the North American University digital wall along with the relevant justifications at the end of this report.

    The cosmic ray proton, helium and CNO fluxes in the 100 TeV energy region from TeV muons and EAS atmospheric Cherenkov light observations of MACRO and EAS-TOP2004In: Astroparticle physics, ISSN 0927-6505, E-ISSN 1873-2852, Vol. 21, no 3, p. 223-240Article in journal (Refereed)
    Abstract [en]

    The primary cosmic ray (CR) proton, helium and CNO fluxes in the energy range 80-300 TeV are studied at the National Gran Sasso Laboratories by means of EAS-TOP (Campo Imperatore, 2005 m a.s.l.) and MACRO (deep underground, 3100 m w.e., the surface energy threshold for a muon reaching the detector being E-mu(th) approximate to 1.3 TeV). The measurement is based on: (a) the selection of primaries based on their energy/nucleon (i.e., with energy/nucleon sufficient to produce a muon with energy larger than 1.3 TeV) and the reconstruction of the shower geometry by means of the muons recorded by MACRO in the deep underground laboratories; (b) the detection of the associated atmospheric Cherenkov light (C.l.) signals by means of the C.l. detector of EAS-TOP. The C.l. density at core distance r > 100 m is directly related to the total primary energy E-0. Proton and helium ("p + He") and proton, helium and CNO ("p + He + CNO") primaries are thus selected at E-0 approximate to 80 TeV, and at E-0 similar or equal to 250 TeV, respectively. Their flux is measured: J(p+He)(80 TeV) = (1.8 +/- 0.4) x 10(-6) m(-1)-s(-1) sr(-1) TeV-1, and J(p+He+CNO)(250 TeV) = (1.1 +/- 0.3) x 10(-7) m(-2)-s(-1) sr(-1) TeV-1, their relative weights being J(p+He)(J(p+He+CNO)) over bar (250 TeV) = 0.78 +/- 0.17. By using the measurements of the proton spectrum obtained from the direct experiments and hadron flux data in the atmosphere, we obtain for the relative weights of the three components at 250 TeV: J(p) : J(He) : J(CNO) = (0.20 +/- 0.08) : (0.58 +/- 0.19) : (0.22 +/- 0.17). This corresponds to the dominance of helium over proton primaries at 100-1000 TeV, and a possible non-negligible contribution from CNO. The lateral distribution of Cherenkov light in Extensive Air Showers (EASs), which is related to the rate of energy deposit of the primary in the atmosphere, is measured for a selected proton and helium primary beam, and good agreement is found when compared with the one calculated with the CORSIKA/QGSJET simulation model.

    The cosmic ray primary composition between 10(15) and 10(16) eV from Extensive Air Showers electromagnetic and TeV muon data2004In: Astroparticle physics, ISSN 0927-6505, E-ISSN 1873-2852, Vol. 20, no 6, p. 641-652Article in journal (Refereed)
    Abstract [en]

    The cosmic ray primary composition in the energy range between 10(15) and 10(16) eV, i.e., around the "knee" of the primary spectrum, has been studied through the combined measurements of the EAS-TOP air shower array (2005 m a. s.l., 10(5) m(2) collecting area) and the MACRO underground detector (963 m.a.s.l., 3100 m w.e. of minimum rock overburden, 920 m(2) effective area) at the National Gran Sasso Laboratories. The used observables are the air shower size (N-c) measured by EAS-TOP and the muon number (N-mu) recorded by MACRO. The two detectors are separated on average by 1200 m of rock, and located at a respective zenith angle of about 30degrees. The energy threshold at the surface for muons reaching the MACRO depth is approximately 1.3 TeV. Such muons are produced in the early stages of the shower development and in a kinematic region quite different from the one relevant for the usual N-mu - N-e studies. The measurement leads to a primary composition becoming heavier at the knee of the primary spectrum, the knee itself resulting from the steepening of the spectrum of a primary light component (p, He) of Deltay = 0.7 +/- 0.4 at E-0 similar to 4 x 10(15) eV. The result confirms the ones reported from the observation of the low energy muons at the surface (typically in the GeV energy range), showing that the conclusions do not depend on the production region kinematics. Thus, the hadronic interaction model used (CORSIKA/QGSJET) provides consistent composition results from data related to secondaries produced in a rapidity region exceeding the central one. Such an evolution of the composition in the knee region supports the "standard" galactic acceleration/propagation models that imply rigidity dependent breaks of the different components.. and therefore breaks occurring at lower energies in the spectra of the light nuclei.

    Dynamic risk measure for BSVIE with jumps and semimartingale issues2019In: Stochastic Analysis and Applications, ISSN 0736-2994, E-ISSN 1532-9356, Vol. 37, no 3, p. 361-376Article in journal (Refereed)
    Abstract [en]

    Risk measure is a fundamental concept in finance and in the insuranceindustry. It is used to adjust life insurance rates. In this article,we will study dynamic risk measures by means of backward stochasticVolterra integral equations (BSVIEs) with jumps. We prove a comparisontheorem for such a type of equations. Since the solution of aBSVIEs is not a semimartingale in general, we will discuss some particularsemimartingale issues.

    Stochastic optimal control of McKean-Vlasov equations with anticipating law2019In: Afrika Matematika, ISSN 1012-9405, E-ISSN 2190-7668, Vol. 30, no 5-6, p. 879-901Article in journal (Refereed)
    Abstract [en]

    We are interested in Pontryagin’s stochastic maximum principle of controlled McKean–Vlasov stochastic differential equations. We allow the law to be anticipating, in the sense that, the coefficients (the drift and the diffusion coefficients) depend not only of the solution at the current time t, but also on the law of the future values of the solution PX(t+δ)" role="presentation">PX(t+δ), for a given positive constant δ" role="presentation">δ. We emphasise that being anticipating w.r.t. the law of the solution process does not mean being anticipative in the sense that it anticipates the driving Brownian motion. As an adjoint equation, a new type of delayed backward stochastic differential equations (BSDE) with implicit terminal condition is obtained. By using that the expectation of any random variable is a function of its law, our BSDE can be written in a simple form. Then, we prove existence and uniqueness of the solution of the delayed BSDE with implicit terminal value, i.e. with terminal value being a function of the law of the solution itself.

    Abstract [en]

    The purpose of this paper is to study the following topics and the relation between them: (i) Optimal singular control of mean-field stochastic differential equations with memory; (ii) reflected advanced mean-field backward stochastic differential equations; and (iii) optimal stopping of mean-field stochastic differential equations. More specifically, we do the following: (1) We prove the existence and uniqueness of the solutions of some reflected advanced memory backward stochastic differential equations; (2) we give sufficient and necessary conditions for an optimal singular control of a memory mean-field stochastic differential equation (MMSDE) with partial information; and (3) we deduce a relation between the optimal singular control of an MMSDE and the optimal stopping of such processes.

    Optimal stopping, randomized stopping and singular control with partial information flowIn: Article in journal (Refereed)
    Abstract [en]

    The purpose of this paper is two-fold: We extend the well-known relation between optimal stopping and randomized stopping of a given stochastic process to a situation where the available information flow is a sub-filtration of the filtration of the process. We call these problems optimal stopping and randomized stopping with partial information. Following an idea of Krylov [K] we introduce a special singular stochastic control problem with partial information and show that this is also equivalent to the partial information optimal stopping and randomized stopping problems. Then we show that the solution of this singular control problem can be expressed in terms of (partial information) variational inequalities, which in turn can be rewritten as a reflected backward stochastic differential equation (RBSDE) with partial information.

    Singular control of SPDEs with space-mean dynamicsIn: Article in journal (Refereed)
    Abstract [en]

    We consider the problem of optimal singular control of a stochastic partial differential equation (SPDE) with space-mean dependence. Such systems are proposed as models for population growth in a random environment. We obtain sufficient and necessary maximum principles for such control problems. The corresponding adjoint equation is a reflected backward stochastic partial differential equation (BSPDE) with space-mean dependence. We prove existence and uniqueness results for such equations. As an application we study optimal harvesting from a population modelled as an SPDE with space-mean dependence.

    Mean-field backward stochastic differential equations and applicationsIn: Article in journal (Refereed)
    Abstract

    In this paper we study the mean-field backward stochastic differential equations (mean-field bsde) of the form

    dY (t) = −f(t, Y (t), Z(t), K(t, ·), E[ϕ(Y (t), Z(t), K(t, ·))])dt + Z(t)dB(t) + R R0 K(t, ζ)N˜(dt, dζ),

    where B is a Brownian motion, N˜ is the compensated Poisson random measure. Under some mild conditions, we prove the existence and uniqueness of the solution triplet (Y, Z, K). It is commonly believed that there is no comparison theorem for general mean-field bsde. However, we prove a comparison theorem for a subclass of these equations.When the mean-field bsde is linear, we give an explicit formula for the first component Y (t) of the solution triplet. Our results are applied to solve a mean-field recursive utility optimization problem in finance.

    Mean-field stochastic control with elephant memory in finite and infinite time horizon2019In: Stochastics: An International Journal of Probablitiy and Stochastic Processes, ISSN 1744-2508, E-ISSN 1744-2516Article in journal (Refereed)
    Abstract [en]

    Our purpose of this paper is to study stochastic control problems for systems driven by mean-field stochastic differential equations with elephant memory, in the sense that the system (like the elephants) never forgets its history. We study both the finite horizon case and the infinite time horizon case. In the finite horizon case, results about existence and uniqueness of solutions of such a system are given. Moreover, we prove sufficient as well as necessary stochastic maximum principles for the optimal control of such systems. We apply our results to solve a mean-field linear quadratic control problem. For infinite horizon, we derive sufficient and necessary maximum principles. As an illustration, we solve an optimal consumption problem from a cash flow modelled by an elephant memory mean-field system.

    Model uncertainty stochastic mean-field control2019In: Stochastic Analysis and Applications, ISSN 0736-2994, E-ISSN 1532-9356, Vol. 37, no 1, p. 36-56Article in journal (Refereed)
    Abstract [en]

    We consider the problem of optimal control of a mean-field stochasticdifferential equation (SDE) under model uncertainty. The model uncertaintyis represented by ambiguity about the law LðXðtÞÞ of the stateX(t) at time t. For example, it could be the law LPðXðtÞÞ of X(t) withrespect to the given, underlying probability measure P. This is the classicalcase when there is no model uncertainty. But it could also be thelaw LQðXðtÞÞ with respect to some other probability measure Q or,more generally, any random measure lðtÞ on R with total mass 1. Werepresent this model uncertainty control problem as a stochastic differentialgame of a mean-field related type SDE with two players. Thecontrol of one of the players, representing the uncertainty of the lawof the state, is a measure-valued stochastic process lðtÞ and the controlof the other player is a classical real-valued stochastic process u(t).This optimal control problem with respect to random probability processeslðtÞ in a non-Markovian setting is a new type of stochastic controlproblems that has not been studied before. By constructing a newHilbert space M of measures, we obtain a sufficient and a necessarymaximum principles for Nash equilibria for such games in the generalnonzero-sum case, and for saddle points in zero-sum games. As anapplication we find an explicit solution of the problem of optimal consumptionunder model uncertainty of a cash flow described by amean-field related type SDE.

    A Hida-Malliavin white noise calculus approach to optimal control2018In: Infinite Dimensional Analysis Quantum Probability and Related Topics, ISSN 0219-0257, Vol. 21, no 3, article id 1850014Article in journal (Refereed)
    Abstract [en]

    The classical maximum principle for optimal stochastic control states that if a control û is optimal, then the corresponding Hamiltonian has a maximum at u = û. The first proofs for this result assumed that the control did not enter the diffusion coefficient. Moreover, it was assumed that there were no jumps in the system. Subsequently, it was discovered by Shige Peng (still assuming no jumps) that one could also allow the diffusion coefficient to depend on the control, provided that the corresponding adjoint backward stochastic differential equation (BSDE) for the first-order derivative was extended to include an extra BSDE for the second-order derivatives. In this paper, we present an alternative approach based on Hida-Malliavin calculus and white noise theory. This enables us to handle the general case with jumps, allowing both the diffusion coefficient and the jump coefficient to depend on the control, and we do not need the extra BSDE with second-order derivatives. The result is illustrated by an example of a constrained linear-quadratic optimal control.

    We consider a problem of optimal control of an infinite horizon system governed by forward–backward stochastic differential equations with delay. Sufficient and necessary maximum principles for optimal control under partial information in infinite horizon are derived. We illustrate our results by an application to a problem of optimal consumption with respect to recursive utility from a cash flow with delay.

    Malliavin calculus and optimal control of stochastic Volterra equations2015In: Journal of Optimization Theory and Applications, ISSN 0022-3239, E-ISSN 1573-2878, Vol. 167, no 3, p. 1070-1094Article in journal (Refereed)
    Abstract [en]

    Solutions of stochastic Volterra (integral) equations are not Markov processes, and therefore, classical methods, such as dynamic programming, cannot be used to study optimal control problems for such equations. However, we show that using Malliavin calculus, it is possible to formulate modified functional types of maximum principle suitable for such systems. This principle also applies to situations where the controller has only partial information available to base her decisions upon. We present both a Mangasarian sufficient condition and a Pontryagin-type maximum principle of this type, and then, we use the results to study some specific examples. In particular, we solve an optimal portfolio problem in a financial market model with memory.

    Study of large hemispherical photomultiplier tubes for the ANTARES neutrino telescope2005In: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, ISSN 0168-9002, E-ISSN 1872-9576, Vol. 555, no 1-2, p. 132-141Article in journal (Refereed)
    Abstract [en]

    The ANTARES neutrino telescope, to be immersed depth in the Mediterranean Sea, will consist of a three-dimensional matrix of 900 large area photomultiplier tubes housed in pressure-resistant glass spheres. The selection of the optimal photomultiplier was a critical step for the project and required an intensive phase of tests and developments carried out in close collaboration with the main manufacturers worldwide. This paper provides an overview of the tests performed by the collaboration and describes in detail the features of the photomultiplier tube chosen for ANTARES. (c) 2005 Elsevier B.V.

    The data acquisition system for the ANTARES neutrino telescope2007In: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, ISSN 0168-9002, E-ISSN 1872-9576, Vol. 570, no 1, p. 107-116Article in journal (Refereed)
    Abstract [en]

    The ANTARES neutrino telescope is being constructed in the Mediterranean Sea. It consists of a large three-dimensional array of photo-multiplier tubes. The data acquisition system of the detector takes care of the digitisation of the photo-multiplier tube signals, data transport, data filtering, and data storage. The detector is operated using a control program interfaced with all elements. The design and the implementation of the data acquisition system are described. (c) 2006 Elsevier B.V.
