    Optimal randomness certification from one entangled bit2016In: Physical Review A. Atomic, Molecular, and Optical Physics, ISSN 1050-2947, E-ISSN 1094-1622, Vol. 93, no 4Article in journal (Refereed)
    Abstract [en]

    By performing local projective measurements on a two-qubit entangled state one can certify in a device-independent way up to one bit of randomness. We show here that general measurements, defined by positive-operator-valued measures, can certify up to two bits of randomness, which is the optimal amount of randomness that can be certified from an entangled bit. General measurements thus provide an advantage over projective ones for device-independent randomness certification.

    Impact and flexural properties of flax fabrics and Lyocell fiber-reinforced bio-based thermoset2011In: Journal of reinforced plastics and composites (Print), ISSN 0731-6844, E-ISSN 1530-7964, Vol. 30, no 8, 685-697 p.Article in journal (Refereed)
    Abstract [en]

    A bio-based thermoset resin was reinforced with flax fabrics and Lyocell fiber. The effect of different weave architectures was studied with four flax fabrics with different architectures: plain, twill (two different types), and dobby. The effect of the outer ply thickness was studied and characterized with flexural and impact testing. Composites manufactured with plain weave reinforcement had the best mechanical properties. The tensile strength, tensile modulus, flexural strength, flexural modulus, and impact strength were 280 MPa, 32 GPa, 250 MPa, 25 GPa, and 75 kJ/m2, respectively. Reinforcements with twill-weave architecture did not impart appreciable flexural strength or flexural modulus even when the outer thickness was increased. Plain- and dobby (basket woven style)-weave architectures gave better reinforcing effects and the flexural properties increased with an increase in outer thickness.Water absorption properties of the composites were studied and it was observed that the hybridization with Lyocell fiber reduced the water uptake. Fieldemission scanning electron microscopy was used to study the micro-structural properties of the composites.

    Biobased Composites Prepared by Compression Molding with a Novel Thermoset Resin from Soybean Oil and a Natural-Fiber Reinforcement2010In: Journal of Applied Polymer Science, ISSN 0021-8995, E-ISSN 1097-4628, Vol. 116, no 3, 1759-1765 p.Article in journal (Refereed)
    Abstract [en]

    Biobased composites were manufactured with a compression-molding technique. Novel thermoset resins from soybean oil were used as a matrix, and flax fibers were used as reinforcements. The air-laid fibers were stacked randomly, the woven fabrics were stacked crosswise (0/90 ), and impregnation was performed manually. The fiber/resin ratio was 60 : 40. The prepared biobased composites were characterized by impact and flexural testing. Scanning electron microscopy of knife-cut cross sections of the specimens was also done to investigate the fiber–matrix interface. Thermogravimetric analysis of the composites was carried out to provide indications of thermal stability. Three resins from soybean oil [methacrylated soybean oil, methacrylic anhydride modified soybean oil (MMSO), and acetic anhydride modified soybean oil] were used as matrices. The impact strength of the composites with MMSO resin reinforced with air-laid flax fibers was 24 kJ/m2, whereas that of the MMSO resin reinforced with woven flax fabric was between 24 and 29 kJ/m2. The flexural strength of the MMSO resin reinforced with air-laid flax fibers was between 83 and 118 MPa, and the flexural modulus was between 4 and 6 GPa, whereas the flexural strength of the MMSO resin reinforced with woven fabric was between 90 and 110 MPa, and the flexural modulus was between 4.87 and 6.1 GPa.

    Preparation of biobased composites using novel thermoset polymers from soybean oil and a natural fibre reinforcement2009Conference paper (Other academic)
    Abstract [en]

    Health related issues, stringent environmental protection policies, search for cost effective and alternative materials, crave for renewability and sustainability and quest for high performance materials for structural applications give the motivation for research in polymer composites and material science. Due to the health, safety and environmental concerns over the conventional synthetic materials and the legislation against their usage both in domestic and industrial applications, alternatives sources that will be comparable in properties are being sought. There is an emerging market for biodegradable polymers which is expected to increase substantially in the coming years.[1] Preparation of Composites Airlaid and woven flax fibre mats were first treated with 4% sodium hydroxide solution for one hour and then washed with plenty of water. This was done in order to remove any residual impurities. The fibres were dried at room temperature for 24 hr and then dried in a vacuum oven for 1hr at a temperature of 105°С. The 8 sheets of the fibre were hand laid cross- wisely and the impregnation was done manually. The fibre/ resin ratio was about 60% to 40%. Methacrylated soybean oil, methacrylic anhydride and acetic anhydride modified soybean oil were the synthesized matrices used. The compression moulding was done at a temperature of 170°С for 5 min at 40bar. Characterisations The tensile testing was performed based on an ISO-test method for tensile tests on plastic materials. The Charpy impact strength of unnotched specimens was evaluated in accordance with ISO 179 using a Zwick test instrument and scanning electron microscopy analysis was done on the fractured specimens. The composites showed various mechanical properties, having impact strengths between 24 and 63 kJ/m² and tensile strength up to 51MPa.

    Kravställning på Incidenthanteringssystem2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The use of IT-related services has increased massively over the past years and it shows no signs to stop. But alongside the usage increasing the risks also increases, because what will happen when the IT-services that so many rely upon suddenly cease to function, or in other ways become inaccessible? To protect against such scenarios it is increasingly more common for IT-service businesses to use incident management, whose purpose is to recover IT-services to their functional state, using predefined processes, should an event occur. It is common for IT-service businesses when implementing an incident management process to use some kind of framework or method to facilitate and streamline its work process, and as of writing this paper, the most used frameworks are ITIL and COBIT.

    It is very common for an IT-service business that in the incident management process develop a system or application whose purpose is to facilitate and streamline the incident management, and these are commonly referred to as Incident Management Systems. Even though ITIL and COBIT being widely used worldwide, there are some weaknesses in them, regarding Incident Management Systems, since both of the frameworks lack focus and depth of what an Incident Management System should manage. Such lack of focus and depth of a vital and central part of the Incident Management process, may prove expensive to IT-service businesses since the business needs to investigate what the system needs to manage, and how to manage it.

    This paper address the problem with ITIL and COBIT lack of focus and depth regarding the central part of the incident management process, the Incident Management System by investigating and reciprocate the following questions.

    Which implied and explicit requirements should an Incident Management System meet?

    Which Incident Management System requirements can be found from the most used frameworks regarding Incident Management?

    How well does the identified requirements match those requirements made by a real world company?

    The target audience for this paper is mainly IT-service business or individuals that considers themselves in need of a compilation of requirements that an Incident Management System should meet and can be used as a supporting tool when implementing or purchasing a new Incident Management System. By identifying requirements that an Incident Management Systems should meet from the most used framework regarding Incident Management, this paper will contribute with means for the implementation of the Incident Management System, reducing the costs for the investigation of demands of such a system. It will also present interested parties with a concrete example, the single case study, to compare with the requirements from the frameworks, contributing with a benchmark for IT-service business to start from when implementing or purchasing an Incident Management System.

    Water absorption in polymers2010Conference paper (Other academic)
    Abstract [en]

    In this work two different examples of water absorbtion in polymers are studied by Monte Carlo simulations. Both of them are of large technical and commercial impotance. The first example is the water absorption in polyethylene cables where the water absorption plays a crucial role in the degradation of the cable insulation and thus should be as low as possible. The second example is bio-based superabsorbents made from denatured protein where water absorption capability is the prime desired property. Methods Gibbs Ensemble Monte Carlo simulations [1] were used to study the hydration of polymers. All simulations are performed with two boxes, one of which is filled with water at the start of the simulation, whereas the other contains polymer molecules and possible ions. The polymer molecules are not allowed to swap boxes whereas the water molecules are allowed to do so thus constituting an osmotic Gibbs ensemble [2]. For the polyethylene a connectivity-altering algorithm was used whereas the protein molecules were simulated using a side-chain regrowth model in addition to traditional Monte Carlo moves. For the polyethylene, the TraPPE [3] force field was used and the protein molecules, the Amber force field [4] was used. Water was modelled using simple point charge models [5]. Electrostatic interactions are treated using Ewald summation methods. The protein molecules were of different amino acid compositions and in different conformations, e.g., β-turns and random coils obtained using the amorphous cell method[6]. Studies were made with different degrees of charging on, e.g., lysine side chains mimicking different ionization states. Results The studies of polyethylene revealed the importance of ions left from the polymerisation catalyst for the absorbtion of water and the concomitant degradation of polyethylene cable insulation. Also the absorption properties of the protein molecules is strongly related to the presence of charged groups and fully charged protein molecules absorb large amounts of water. However, neither native nor denatured protein molecules show superabsorbing properties (i.e. absorbing hundreds of times their own mass) as they show in experimental studies and the reasons for this discrepancy will be discussed.

    Development and dissemination strategies for accelerating biogas production in Nigeria2014In: BioResources, ISSN 1930-2126, E-ISSN 1930-2126, Vol. 9, no 3, 5707-5737 p.Article in journal (Refereed)
    Abstract [en]

    Following the worsening energy crisis of unreliable electricity and unaffordable petroleum products coupled with the increase number of poverty-stricken people in Nigeria, the populace is desperately in need of cheap alternative energy supplies that will replace or complement the existing energy sources. Previous efforts by the government in tackling the challenge by citizenship sensitization of the need for introduction of biofuel into the country’s energy mix have not yielded the expected results because of a lack of sustained government effort. In light of the shortcomings, this study assesses the current potential of available biomass feedstock for biogas production in Nigeria, and further proposes appropriate biogas plants, depending on feedstock type and quantity, for the six geopolitical zones in Nigeria. Besides, the study proposes government-driven biogas development systems that could be effectively used to harness, using biogas technology, the estimated 270 TWh of potential electrical energy from 181 million tonnes of available biomass, in the advancement of electricity generation and consequent improvement of welfare in Nigeria.

    Creating and sustaining successful knowledge management in purposeful communities: summary of key experiences from pioneers2008In: Systems research and behavioral science, ISSN 1092-7026, E-ISSN 1099-1743, Vol. 25, no 5, 615-626 p.Article in journal (Refereed)
    Abstract [en]

    Based on research organized as a number of workshops, case studies and interviews with experienced practitioners as well as academics, we present in this report the most important findings on how to create and sustain successful knowledge management in a community environment. The cases, workshops and interviews deal specifically with the Microsoft Solutions Sharing Network (SSN) program, but the findings, conclusions and preliminary recommendations can be applied more generally to the development of any knowledge management community. A key conclusion is that the bulk of efforts toward creating successful knowledge management communities focus oil less technical, or softer aspects like leadership, culture, social settings and value of participation. However, these are essential, but not sufficient, ingredients for success. Technical issues, issues regarding development and customization of the tools used to facilitate knowledge management (for example, the SSN web portal), and emerging legal issues surrounding the sharing of intellectual property UP) may be perceived as somewhat less important to the participants, but are nevertheless key factors in the long term success of these communities. It is also concluded that the foundation for successful collaboration is primarily laid in the initial phases of community development. A community must make a positive impression oil its participants from the very beginning because most people will not give it a second chance. In this report we have highlighted three important areas to consider when establishing portals for knowledge management: Leadership, Purpose and Process/Infrastructure. A leadership with high credibility in the subject is needed to lead the participants in the right direction, manage the cultural processes and to make sure that relevant content can be found. Initially it is the content that brings people to a specific community. Thus, there has to be some common purpose that not only needs to be in congruence with the professional role of the participants but also be inspiring for them as well. Additionally, the community should have some sort of process that the participants can understand and suits the way they would like to interact. Face-to-face meetings and networking activities create trust which is important to get the process started. Language, IT platform, support and rules governing the contribution, creation and sharing of 'knowledge' for the community are other concerns that need to be considered within the process.

    Turning the Internet Around: e-Me: The Students Ideal e-Service2006Conference paper (Refereed)
    Abstract [en]

    Today students, as many other groups of citizens, are offered, indeed required to use, a rapidly increasing number of e-Services. They range from school and course sites to interactions with authorities as well as companies offering student discounts. This paper reports on a pioneering project in Sweden with a radical approach to this, namely to issue the student with a electronic assistant, an e-Me, that schools, authorities and companies are required to address when interacting with the student. A larger number of students and partners, universities, companies and authorities, have been engaged in the design of such an e-Me. It might be thought of as turning the internet around – rather than having students keep track of sites, they will have to come to the students and interact with them in the way specified by them.

    Abstract [en]

    Electro active textile fibers are key components in smart and interactive textile applications. In our previous study, we produced poly(3,4-ethylenedioxythiophene) (PEDOT) coat edviscose fibers by using oxidative chemical vapordeposition (OCVD) technique. We tried FeCl3 as oxidant and found optimum reaction conditions at which better electrical as well as mechanical properties of conductive fibers could be achieved.

    Work on Spoken (Multimodal) Language Corpora in South Africa2010Conference paper (Refereed)
    Abstract [en]

    This paper describes past, ongoing and planned work on the collection and transcription of spoken language samples for all the South African official languages and as part of this the training of researchers in corpus linguistic research skills. More specifically the work has involved (and still involves) establishing an international corpus linguistic network linked to a network hub at a UNISA website and the development of research tools, a corpus research guide and workbook for multimodal communication and spoken language corpus research. As an example of the work we are doing and hope to do more of in the future, we present a small pilot study of the influence of English and Afrikaans on the 100 most frequent words in spoken Xhosa as this is evidenced in the corpus of spoken interaction we have gathered so far. Other planned work, besides work on spoken language phenomena, involves comparison of spoken and written language and work on communicative body movements (gestures) and their relation to speech.

    Hesitation in Intercultural Communication: Some Observations and Analyses on Interpreting Shoulder Shrugging2010In: Computing and Communication: Lecture Notes in Computer Science, (LNCS) / [ed] T. Ishida, Springer , 2010, 55-70 p.Chapter in book (Other academic)
    Abstract [en]

    This paper concerns the different ways in which hesitation, and hesitation related phenomena like uncertainty, doubt and other phenomena where lack of knowledge is involved are expressed in different cultures. The paper focuses especially on shoulder shrugging as a signal of hesitation or uncertainty, and starts from the observation that shoulder shrugging has different interpretations depending on the interlocutor’s cultural background. It is not commonly used in Eastern cultures while in Western cultures it is a sign of uncertainty and ignorance. The paper reports a small study on the differences in interpretation of a particular video tape gesture, and draws some preliminary conclusions of how this affects intercultural communication between human interlocutors and between humans and conversational agents.

    The analysis of embodied communicative feedback in multimodal corpora: a prerequisite for behavior simulation2008In: Language resources and evaluation, ISSN 1574-020X, E-ISSN 1574-0218, Vol. 41, no 3-4, 255-272 p.Article in journal (Refereed)
    Abstract [en]

    Communicative feedback refers to unobtrusive (usually short) vocal or bodily expressions whereby a recipient of information can inform a contributor of information about whether he/she is able and willing to communicate, perceive the information, and understand the information. This paper provides a theory for embodied communicative feedback, describing the different dimensions and features involved. It also provides a corpus analysis part, describing a first data coding and analysis method geared to find the features postulated by the theory. The corpus analysis part describes different methods and statistical procedures and discusses their applicability and the possible insights gained with these methods.

    Construction and annotation of a corpus of contemporary Nepali2008In: Corpora, ISSN 1749-5032, E-ISSN 1755-1676, Vol. 3, no 2, 213-225 p.Article in journal (Refereed)
    Abstract [en]

    In this paper, we describe the construction of the 14-million-word Nepali National Corpus (NNC). This corpus includes both spoken and written data, the latter incorporating a Nepali match for FLOB and a broader collection of text. Additional resources within the NNC include parallel data (English–Nepali and Nepali–English) and a speech corpus. The NNC is encoded as Unicode text and marked up in CES-compatible XML. The whole corpus is also annotated with part-of-speech tags. We describe the process of devising a tagset and retraining tagger software for the Nepali language, for which there were no existing corpus resources. Finally, we explore some present and future applications of the corpus, including lexicography, NLP, and grammatical research.

    Self Services and Disservices: Improving Avatars with Co-Design2014Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Corporations and government agencies that use Avatars claim there are substantial benefits for using them in their respective organizations; including 24/7 service availability, quick answers without a phone queue, and improved consistency in the responses provided. “There are also potential cost savings by having an Avatar answering questions compared to using personnel” (Lind and Salomonson, 2006). However, these benefits may not be great enough as the lack of possible human communication may lead to alienation between individuals and organisations. Furthermore, a robot may “miss out” on business opportunities that a human would act on. A robot will not hear and understand nuances in speech, with the risk that a potentially problematic situation may not be adequately resolved, leading to dissatisfaction with products and services delivered. Many companies measure the satisfaction with Avatars by analysing question and answer logs to see if the Avatar appears to give satisfactory answers. Few of these companies have actually asked their customers (e.g. IKEA and SAS until recently) what they really feel about the quality of the answers they receive. User Centered Design, Participatory Design and other methods are the preferred ways of developing such systems, but these do not include all stakeholders. This thesis addresses this exclusion of all stakeholders by applying a co-design research approach for developing avatars for e-Services. Case studies from Mark Municipality, Sweden and Scandinavian Airlines Systems (SAS) are presented in this thesis showing how improvements of service quality aspects with Avatars can be managed by applying a four-step Co-Design research approach. From the first step of Co-Design, through interviews, log analysis and a channel survey, findings show that the failed dialogues with Avatars Eva (SAS) and Elin (Mark) are mainly concerned with five factors: interactivity; dialogue capability; consistency; knowledge; and synonyms. In the second step of carrying out customer workshops, a number of ideal scenarios are suggested for the Avatars to perform better. In the third step, SAS decision makers decided to implement the first three scenarios: Eva’s synonyms, knowledge and consistency. Mark decision makers decided to shut down their Avatar Elin, as they did not believe they had the necessary resources. In the fourth step, another channel survey was carried out for SAS as well as a new log analysis in order to know the impact of the redevelopment of the above three scenarios. An important result of the study was that the company adopted the continuous use of Co-Design as an approach to continuous improvement of the service quality performed by the Avatar Eva. This, for example, led to an increase of 14 percentage points on the users overall satisfaction level. The results also open a new set of questions framing the relation and transformation between Co-Design as a research approach for knowledge creation and Co-Design as a method for innovation and service quality improvements. This thesis also presents an Extended Co-Design Model, which illustrates how Co-Design inspires SAS staff. In addition, the staff of the supplier of the Avatar use it for other functions within and without SAS.

    Successful use of avatar/e-services: powerful, but needs a knowledge manager with proper methods2011Conference paper (Refereed)
    Abstract [en]

    In this paper we are presenting some theoretical background, some practical applications and some future scenarios of the use of the human being as a metaphor for design and implementation of e-services/avatars. The main conclusion is that e-services/avatars technology is a powerful concept but without a new profession as knowledge manager in the background, there’s a big risk for failure. We are also presenting a co-design model as a tool for the knowledge manager.

    Abstract [en]

    The Co-design practices are carried out in different fields of studies. Some of the key advocates of Co-design originate from business. In this study the four steps of Co-design approach is applied. From the first step of Co-design, through interviews, log analysis and a channel survey, findings show that the failed dialogues with Avatar Eva are mainly concerned with five factors: interactivity; dialogue capability; consistency; knowledge; and synonyms. In the second step, carrying out customer workshops, we suggested ten ideal scenarios for Avatar Eva to perform better. In the third step, SAS decision makers decided to implement the first three scenarios: Eva’s synonyms; knowledge and Eva’s consistency. In the fourth step, another channel survey was carried out as well as a new log analysis to know the impact of the redevelopment above three scenarios. An important result of the study was that the company adopted a continuous use of Co-design as an approach of continuous improvement of the service quality performed by the Avatar Eva. It also opens a new set of questions framing the relation and transformation between Co-design as a research approach for knowledge creation and Co-design as a method for innovation and service quality improvements. The study presents an Extended Co-design Model, which illustrates how the Co-design inspires staff to use it for other functions within and without the SAS.
