    SciChallenge: A Social Media Aware Platform for Contest-Based STEM Education and Motivation of Young Students2019In: IEEE Transactions on Learning Technologies, ISSN 1939-1382, E-ISSN 1939-1382, Vol. 12, no 1, p. 98-111Article in journal (Refereed)
    Abstract [en]

    Scientific and technological innovations have become increasingly important as we face the benefits and challenges of both globalization and a knowledge-based economy. Still, enrolment rates in STEM degrees are low in many European countries and consequently there is a lack of adequately educated workforce in industries. We believe that this can be mainly attributed to pedagogical issues, such as the lack of engaging hands-on activities utilized for science and math education in middle and high schools. In this paper, we report our work in the SciChallenge European project, which aims at increasing the interest of pre-university students in STEM disciplines, through its distinguishing feature, the systematic use of social media for providing and evaluation of the student-generated content. A social media-aware contest and platform were thus developed and tested in a pan-European contest that attracted >700 participants. The statistical analysis and results revealed that the platform and contest positively influenced participants STEM learning and motivation, while only the gender factor for the younger study group appeared to affect the outcomes (confidence level – p<.05).

    Kommunikationskanaler vid intern nyhetsspridning: En fallstudie om hur kommunikationskanaler påverkar den upplevda kommunikationseffektiviteten vid nyhetsspridning2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Communication is an important function within organizations and the ways of communicating have developed rapidly due to technological development, which can make it difficult to know which communication channel that is best to use in different situations. This report is based on a case study were the perceived communication efficiency tended to vary depending on which communication channel that was used. Previous research shows how the choice of communication channels can affect the communication efficiency, however, it does not show this from the perspective of news as an information type. Therefore, it was considered interesting to study how different communication channels affect the communication efficiency in terms of news distribution.

     

    The aim of this study was to illustrate and describe how communication channels affect the perceived communication efficiency when the information that is transferred consists of news. To achieve this, the following research question would be answered:

     

    • What advantages and disadvantages do employees experience with communication channels regarding the communication efficiency for news distribution in a large national company?

     

    Theories that have been applied in the study are Media Richness Theory and Osgood and Schramms circular communication model. Theories have been used to explain how news distribution takes place in the case company and to illustrate and possibly explain the problems that the company experience with news distribution.

     

    Data was collected by applying a qualitative method in which semi-structured interviews have been used. The result shows that respondents experience both advantages and disadvantages with all the communication channels and that the perceived communication efficiency tended to vary depending on which kind of news. When the result was set against the research question and the theoretical framework, advantages and disadvantages that were experienced, turned out to be depending on if the news were routine or non-routine and how it was matched with a rich or poor communication channel, which Media Richness Theory also declare. 

     

    The conclusion of this study shows that news distribution through face to face and telephone enables direct interaction and transmission of emotions, however, emotions are not transmitted as well through telephone as face to face. The many signals can also be experienced as overwhelmingly. E-mail, intranet and signboard are effective in terms of time and are not as depending on time and space. In addition, the possibility of direct interaction and transmission of feelings is limited. The result indicates that advantages and disadvantages with the communication channels seems to be linked to whether the channel is perceived as suitable to transfer different kinds of news. Rich communication channels are perceived to be effective for transmitting non-routine news and poor channels are perceived to be effective for transmitting routine news.

    WAN-optimering för sjöfarten: En möjlighet att effektivisera datakommunikationen till sjöss2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Shipboard operations have become more reliant of data communication and many of the duties on board may be facilitated if the crew can access information stored elsewhere. The broadband connection between ship and shore is mostly done via satellite communication where long distances and limited data rate results in inefficient data communication. This study examines network optimization and the performance improvement this can have regarding slow WAN connections via satellite. The survey showed that the biggest issue with data communication via satellite is the signal delay caused by the long transmission distance which means that there will be performance degradation for data traffic and users will experience the data communication as slow. To solve this there is equipment that enhances the performance of the connection and handles the data communication by implementing various techniques. To investigate how much the performance improvement can be this study carried out a number of experiments with network optimization equipment.  The experiments evaluated file transfer with and without network optimization. The results show that the network optimization gives a major performance improvement regarding file transfer.

    Optimizing Condition Monitoring of Big Data Systems2017In: Proceedings of the 2017 International Conference on Data Mining: DMIN'17 / [ed] Robert Stahlbock, Mahmoud Abou-Nasr, Gary M. Weiss, CSREA Press, 2017, p. 127-131Conference paper (Refereed)
    Abstract [en]

    Industrial communication networks are common in a number of manufacturing organisations. The high availability of these networks is crucial for smooth plant operations. Therefore local and remote diagnostics of these networks is of primary importance in determining issues relating to plant reliability and availability. Condition Monitoring (CM) techniques when connected to a network provide a diagnostic system for remote monitoring of manufacturing equipment. The system monitors the health of the network and the equipment and is therefore able to predict performance. However, this leads to the collection, storage and analyses of large amounts of data, which must provide value. These large data sets are commonly referred to as Big Data. This paper presents a general concept of the use of condition monitoring and big data systems to show how they complement each other to provide valuable data to enhance manufacturing competiveness.

    Potential Architecture for Future Generation "Green" Wireless Base Station2009In: 2009 4th International Symposium on Wireless and Pervasive Computing, ISWPC 2009, IEEE, 2009, article id 4800602Conference paper (Refereed)
    Abstract [en]

    Current radio frequency power amplifiers (PAs) in 3G base stations have very high power consumption leading to a hefty cost and negative environmental impact. In this paper, we propose a potential architecture design for future wireless base station. Issues associated with components of the architecture are investigated. A comparison of PA with pulse width modulation drive and PA with envelope elimination and restoration (EER) drive is offered. EER-driven PA promises high efficiency over a wide dynamic range but has bandwidth expansion problems. A novel approach which reduces bandwidth expansion on the envelope by 54% is proposed. A modulator is used to convert amplitude and phase information into the edges of a pulse train. The modulator also eradicates some analog components present in traditional base station design.

    A potential transmitter architecture for future generation green wireless base station2009In: EURASIP Journal on Wireless Communications and Networking, ISSN 1687-1472, E-ISSN 1687-1499, article id 821846Article in journal (Refereed)
    Abstract [en]

    Current radio frequency power amplifiers in 3G base stations have very high power consumption leading to a hefty cost and negative environmental impact. In this paper, we propose a potential architecture design for future wireless base station. Issues associated with components of the architecture are investigated. The all-digital transmitter architecture uses a combination of envelope elimination and restoration (EER) and pulse width modulation (PWM)/pulse position modulation (PPM) modulation. The performance of this architecture is predicted from the measured output power and efficiency curves of a GaN amplifier. 57% efficiency is obtained for an OFDM signal limited to 8 dB peak to average power ratio. The PWM/PPM drive signal is generated using the improved Cartesian sigma delta techniques. It is shown that an RF oversampling by a factor of four meets the WLAN spectral mask, and WCDMA specification is met by an RF oversampling of sixteen.

    Standardsystem och användbarhet: Hur ska man som utvecklare säkra att användbarhet uppnås i små SharePoint-projekt?2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today, ICT (Information and Communication Technology) is often used to distribute and communicate information internal and external. One of the great tools for information management is the intranet. This research is focused on usability regarding small SharePoint-projects. Usability covers the factors: usefulness, customization and user acceptance. A small SharePoint-project (less than 300 working hours) has fewer resources available for focusing on usability.

    The purpose with this research is to examine developers’ attitudes regarding usability and how usability is best achieved in small projects where resources are limited. A quantitative method has been used to conduct a case study consisting of three developers in a consulting company. The interviews were semi-structured.

    The result from the research concludes that user acceptance is the key factor for an intranet to be perceived as useful by the users. Usefulness in a standard SharePoint solution is relatively defined and in place. Customization of a solution instead of using the built-in standards is often more costly and resource intensive. Developers should therefore focus on education, user involvement, communication and other factors that may increase acceptance among the end users.

    Sociala Intranät: Dess användning, möjligheter och risker2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Organizations over the world increasingly start to realize the possibilities of the use of a social intranet, also known as Enterprise 2.0. The social intranets can be used to collaborate and communicate with colleagues in the workplace. Both Cook (2008) and Coope (Barnett, 2011) say that Enterprise 2.0 is about to fundamentally change the way organizations communicate. But do companies know how these tools can be used?

    The study emanates from three questions:

    • How can social intranets be used in business?
    • How can internal communication and collaboration get easier through the use of a social intranet?
    • What are the possible risks with the use of social intranets?

    In this study we have in a qualitative manner been interviewing two companies that currently use social intranets in their daily activities – Securitas and Skåneme-jerier. The interviews where performed via telephone with two people familiar with the respective social intranets. We have also sent out a questionnaire via e-mail to a user group of each company's intranet, to gain knowledge of users' opi-nions.

    The interviews show that both companies agree that it is important for peers to communicate and exchange information and knowledge with each other. The so-cial intranets are used both for communication, collecting employees' knowledge, and to ease the employees information need by gathering all information at the same place. Respondents also pointed out the advantage of written information and knowledge. As it is written it is also searchable. It will also remain in the organiza-tion even though the creator might leave the company. The fact that all users can edit for example wikis and files on the intranet can be used to keep information up to date.

    The Open Sustainability Project: A Linked Data Approach to LCA2010In: LCA X, Bridging Science, Policy, and the Public 2-4 November 2010, Portland, Oregon, 2010Conference paper (Other academic)
    Abstract [en]

    The proprietary nature of LCA tools and information limits widespread adoption of sustainability measures. We introduce the Open Sustainability Project(OSP), a Linked Data resource for broadening access to LCA in an effort to increase the transparency and accuracy of environmental impact assessments(2, 9).The OSP applies Free and Open Source Software(FOSS) principles and Linked Data structures to LCA standards and reporting so that communities including students, SME’s and the general public can participate in the assessment and verification of sustainability practices(1,6). The highly flexible data format allows disparate data sources and assessments to be compared along an open standard compliant with ISO 14048 reporting(5, 8, 12).In addition, the OSP makes available a free database of Life Cycle Assessment data using an approach based on Linked Data and RESTful interfaces which supports the development of rich third-party applications for specific user groups and industries(7). This novel combination of linked data and web-based tools is inherently transparent so that LCA practices can be standardized, compared and verified by a broad community.The OSP is an international collaboration between academics, government and industry groups leveraging expertise in LCA, Open Data and web-based tools for sustainability(10). Our first Open Source and Open Data web sustainability tools have confirmed the potential to engage a wider audience, with over two thousand registered users, three thousand environmental assessments performed and over 330,000 page views from more than 75 countries since September 2009(3, 4, 11). The OSP aims to expand reach of LCA through a free and open Application Programming Interface(API) to support distributed development of third-party applications for sustainability assessment through the emerging metrics for social and environmental sustainability(a free LCA "App Store"). These applications are intended to disseminate LCA standards, encourage transparency in environmental reporting and leverage Collective Intelligence in the collection, publication and verification of LCA.The OSP aims to transform LCA into a collaborative process where data collection, analysis, assessment and reporting benefit from the feedback and ideas of a growing worldwide LCA community.

    The ICT Systems Developments in Maintenance: From Data Processing into Knowledge Driven Approaches2014In: Proceedings of the 15th European conference on Knowledge management, (ECKM 2014) / [ed] Carla Vivas, Pedro Sequeira, Academic Conferences Limited, 2014, Vol. 1-3, p. 182-188Conference paper (Refereed)
    Abstract [en]

    The paper goes through the developments of Information and Communication Technologies (ICTs) in the area of Condition Monitoring (CM) and Maintenance with the aim to understand the current state of the ICTs developments in the area of interest as well as their future prospects. The findings are ordered into a framework, which emphasizes the diverse maturity aspects when it comes to the use of these technologies. The results show that the researchers are working with various ICT applications that are in the different eras of the framework. There are findings that support the last era, i.e. the fourth era, but those findings are fewer. However, the applications that support this last era, even if they are at the primary stage, is the e-maintenance approach especially when the knowledge driven approaches are considered in their applications. The e-maintenance approach apart from its integration capabilities also considers other important aspects such as collaboration, cooperation, and organisational learning as well as companies' strategies such as the condition based maintenance, etc. it is, therefore, important to consider the e-maintenance approach as a facilitator for the entrance into the fourth era, which promises sustainability in the use of the ICTs for the domain of interests as well as higher organizational performance

    Mobile Information Systems in Maintenance Engineering and Asset Management2016In: Journal of Societal Studies, ISSN 2029-2236, Vol. 8, no 2, p. 180-197Article in journal (Refereed)
    Abstract [en]

    The objective of this paper is to provide a profound insight into important characteristics with regard to the integration of mobile technology into the area of industrial maintenance. The aspects highlighted in the paper uncover, for instance, acceptance models and best practices, as well as the financial impact of mobile technologies in the domain of interest. Moreover, the paper pinpoints some important characteristics that impede full integration of these technologies into this area. In addition, the economic benefits and the current situation with regard to mobile integration are highlighted. In addition, relevant literature and theories are analysed and discussed. Furthermore, the industrial integration of mobile technologies is outlined. The results indicate that there is a tendency to place an emphasis on the technical aspects of mobile devices rather than on understanding the organisational context, which affects the integration of mobile technologies into this domain.

    The work provides a thorough understanding of best practices and aspects to consider for the successful integration of mobile technologies in this area. This is because the use of mobile devices enables maintenance staff to gain access to information and services pertaining to the task in hand in real time, as long as some form of network access is provided. Users of these devices thus become mobile actors who dynamically interact with the physical environment in the workplace and support information systems, leading to a faster response to events and improved organizational performance.

    Abstract [en]

    The use of mobile devices enables maintenance staff to gain access to information and services relevant to the task in hand in near real time and wherever some form of network access is provided. Essentially, mobile device users become mobile actors who dynamically interact with the physical environment, i.e. workplace, and supporting information systems, leading to faster response to events and an increased performance. This paper provides insight into the acceptance prospects and best practices of the mobile technologies in the area of maintenance. Furthermore, the potential financial impact is discussed as a key driver for the adoption of mobile technologies in the maintenance practice.

    Abstract [en]

    Product lifecycle simulation (PLCS) has been given ever moreattention as the manufacturers are competing with the quality and lifecyclecosts of their products. Especially, the need of companies to try to get a strongposition in providing services for their products and thus to make themselvesless vulnerable to changes in the market has led to high interest in PLCS. Ashort summary of current status of PLCS is presented especially related to thepoor integration of data in product lifecycle management systems and in PLCS.The potential of applying semantic data management to solve these problems isthoroughly discussed in the light of recent development. A basic roadmap howthe above-described problems could be tackled with open software solutions ispresented. Finally, this paper reviews the emergent Web technologies such asthe Semantic Web framework and the Web services.

    In general, when working with the robot industry, there are many factors to consider. Therefore, the process from a non-existing product to an existing product involves many steps that can be time-to consume and error-prone. This thesis will examine the opportunities for automation in the industrial system and the problems that could occur. A little bit of the focus will also be put on Domain Specific Language (DSL) and the exchange of data between two DSLs.The automation of the industry is getting a big thing and there exist ways to integrate software automation within the industry. The research has been done by literature studies and experimenting with a software to exchange information between two DSL-applications. The result shows that there are some standard technologies that could be used in the integration of automation software, but also why automatization could create other problems. The result also shows that it’s possible to exchange information between two DSLs but it can be a little bit complicated.

    ICT tools usage in Virtual teams: Analysis of the correlation between the ICT Toolscapabilities & Virtual teams challenges.2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This quantitative research study focuses on the capabilities of ICT tools used by virtualteams and seeks to find out what, if any, correlation between the ICT tools capabilitiesand challenges that virtual teams face exist. The study addresses four prominent virtualteam challenges: forming trust and relationships, information overload, communicationbreakdown, lack of team synergy and cohesion. It analyses ICT tools and establishhypothesis using MST theory and the existing research in this field. The data analysis isconducted using Spearman’s Rho correlation. The findings show that the correlationbetween ICT tools usage and the challenges that virtual teams face are not statisticallysignificant to establish a link between virtual team challenges and ICT tools usage. Thiscould mean that a significantly larger sample is required to establish the link betweenthese two variables. It could also mean that the virtual team challenges need to be reevaluatedas the collected data suggests that the discussed challenges are rarelyexperienced by virtual teams. Therefore, further studies are needed in order to establishthe correlation between the virtual team challenges and ICT tools usage.

    Chirp Sounding and HF Application: SDR Technology Implementation2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    From a HF propagation point of view, the ionospheric layers act as partially conducting media (plasma) in which a transmitted radio wave can reflect upon.A way of determining whether a radio wave with a given frequency will reflect from the ionosphere or completely penetrate is to utilize special radar instruments know as ionosondes or chirp sounders. The technique is widely used by amateur enthusiasts and military radio users for monitoring available radio channel links between two remote locations and can often serve as a base for HF radio prognoses.The objective of this Bachelor’s Thesis was to explore, implement and test a single channel receiver for monitoring ionospheric sounders. The implementation is based on Software Defined Radio (SDR) technology and relies on the GNU Chirp Sounder (gcs) open source script program.

    Knowledge management practices in academic libraries: The case of NTUA Central Library2018Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    The last years, libraries and information centers, as well as other organizations are attempting to survive in a knowledge-driven society. Moreover, they are called upon to redefine their structure and management processes in order to increase their competitive advantage through their learning capability and their knowledge assets. Knowledge has become their core element that contributes to the development and improvement of their services through knowledge management (KM) initiatives, connected with knowledge assets creation, sharing, and exploitation.

    This study is a qualitative research that has been conducted in NTUA Central Library with main research object the Department of Information and Users’ Services. The study examines the knowledge management (KM) perception in the Department and by extension, the library. It aims to identify the adopted KM practices, investigate the KM process through knowledge creation and sharing, collaboration and communication among employees and external collaborators and finally, to propose new methods and techniques through a KM strategy, for improving the Department and library’s internal operation and services provision. The study’s goal is to present the current situation of one of the biggest Greek academic libraries regarding KM initiatives and to draw attention on the academic libraries’ changing role in the new digital era and the opportunities that KM provides them to participate in the knowledge-based economy and the knowledge-based society.

    The importance of this study lies on the fact that few researches have been conducted in Greek academic libraries and the results have presented that they demonstrate little attempt to adopt KM practices and rather, to establish a clear KM strategy. In this context, the study is trying to clarify the importance of focusing on people as libraries’ knowledge resource connected with their knowledge and experience, which defined as “intellectual assets” that need to be recorded, classified, updated and definitely shared, in order to become searchable and accessible.

    It is a case study, conducted through an interpretive approach, following a holistic ethnography tradition. The research methods used for the data collection were the methods of participant observation and semi-structured interviews. The data collected have been analyzed through the six (6) phases of the thematic analysis, while methods data validation have been used to ensure their reliability.

    In conclusion, the study presents results connected with the Department’s knowledge specification (tacit and explicit), the process of knowledge sharing by mentioning the people involving, the methods and tools. Furthermore, the weaknesses the Department faces are presented regarding employees’ involvement – mostly connected with communication and collaboration – and the systems and resources management. Finally, the anticipated future challenges are presented and analyzed, as defined by the library’s role, the employees’ role and the KM role.

    Viktiga faktorer för användandet av mobila betalningar2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning

    Bara de senaste åren har det lanserats ett flertal nya betalningstjänster för mobiltelefoner, men ingen har fått det genomslag som förväntades. Varför tar inte konsumenterna till sig dessa lösningar?  Denna studie lyfter fram faktorer som har direkt påverkan för användandet av dessa nya tekniker. Faktorerna har identifierats med hjälp av vår litteraturstudie på utökade TAM-modeller från tidigare forskning som försöker förklara acceptans och adoptering av mobila betalningar. Faktorerna som framkom genom litteraturstudien är grunden för vår kvantitativa undersökning, som använder enkäter för insamlandet av data. Dessa faktorer utvärderas tillsammans med två egenhändigt framtagna faktorer för att identifiera vilka faktorer som är viktigast för anammandet av mobila betalningstjänster. Målsättningen var att nå ut till en så stor målgrupp som möjligt för att resultatet skulle bli generaliserbart. Resultatet blev inte helt som vi hade förväntat oss. Faktorer som användarvänlighet, användbarhet och kompabilitet var av ytterst stor vikt, medan säkerhet som tidigare forskning lyfte fram som den viktigaste inte fick alls samma betydelse i vår undersökning.

    Context-Aware P2P Network Construction2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    With growing number of devices connected to the network, there is a greater need for use of Peer-to-Peer (P2P) networks and distributed P2P protocols.Devices participating in the P2P network do not usually need to use any central server that links up connections. It has many advantages but it needs to use so-called overlay network that consists of protocols used for traffic routing and decision making. Protocols used in today’s P2P networks are mostly not considerate of particular participating nodes and all the nodes in the network are usually equal. This can have negative impacts on network performance. In order to avoid or reduce some unwanted negative impacts, it would be advantageous if the overlay network could route traffic and make decisions according to context information like battery levels or connection speeds. This work reviews a few popular P2P overlay networks and based on that it introduces an improvement of one of them – Chord. The structure of the improved version of the Chord protocol called Context-Aware Chord is described. Then results of the evaluation are presented. With a use of the improved protocol, nodes can participate longer in the network and throughput of lookup messages is improved.

    Effekter av tillväxt genom ett informationslogistiskt perspektiv: En studie som belyser ett tillverkande företags expansiva tillväxt och transporter2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Many companies have experienced growth within their organizations over the past fewyears, which has influenced these companies’ internal and external organizational structure.Companies have been affected by globalization since the geographical boundaries have been erased, which has led to an increase in demand for products and transportationrequirements. Previous research shows that there is a significant increase in a company’stransportation costs during periods of growth, which therefore requires an improved control over these costs.

    Based on the purpose of the research was to find a suitable and theoretical framework in order to identify and visually highlight the Information logistics’ effects by growth. The purpose of this research was to investigate and explore the effects of expansive growth during a specific period of time and how that effects a manufacturing company through an Information logistics perspective, with limitation to transport.

    The research in this study has been answered with the help of a qualitative method in which semi-structured interviews have been used to collect empirical data. Then this data has been analyzed through the three different approaches which is description, systematisation and categorization and the answers are handled ethically.

    The result of the case study showed that the administrative work has not been prioritized during a period of growth. Through the developed theoretical framework TOEI, the result has been analyzed and the Information logistics’ effects could be identified in the four main categories technical, organizational, environmental and individual. The case study concluded that companies affected by rapid growth experience the following risk factors: information overflow, increasing work assignment, lack of time and uncontrolled cost support.

    Technology In Policing: An ethnographic study of the use of information and communication technology within Bedfordshire police force2018Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    Policing in The United Kingdom is an intricate business, balancing the enforcement of statute and other laws while dealing with public safety and security. Policing engages a diverse and complicated set of organisational structures and processes relying heavily on the skill and expertise of officers on the ground. Their role in preventing and or intercepting crime before, during and after it occurs is integral to sustaining peace, security, law and order in communities. The police operational and logistics staff work day to day with information and communication technologies, ranging from conventional databases and information systems to ubiquitous and specialised tools.  Understanding the use of technology and its management in policing has formed the backbone of this research conducted through a qualitative approach.

    This study adopted an interpretive paradigmic analytical lens using ethnography situated in the workplace as a methodology. The qualitative study took the form of field immersion for nine months using interviewing, and shadowing/observation to suit the complexity of the socio-technical context. Analysis was conducted using thematic analytical methods. Understanding how the police force interact with and shape the way that information and communication technologies enable them to fight crime is, then, the subject of this thesis.

    The findings highlighted the complexities and  intricacies involved in the use of technology, identifying unique differentiations in the way technology is engaged and integrated into policing including comparative understanding relative to other sectors and industries.  On the whole the central features of this work highlight understanding of the role information and communication technologies; usefulness, usage in practice and operational activity, strategic business goals, knowledge management, business intelligence and intelligence led architecture, governance and performance models in policing the county of Bedfordshire, England.

    Security in Mobile Ad-Hoc Networks2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

                                           

    Abstract

    The number of wireless networks has been growing incessantly during the recent years. Ad hoc networks transmit digital data through radio frequency or wireless communications links, which is an open medium. According to this fact it is important to gain substantial knowledge about the advantages and the drawbacks associated with them for network security purposes. According to the vulnerability of these networks (wireless Ad hoc) to malicious attacks and hackers, there seems to be a necessity to address the potential risks of using these networks.

    An Ad-Hoc is a system of wireless mobile nodes that dynamically self-organize in temporary network topologies. People and vehicles can thus be internetworked in areas without a preexisting communication infrastructure or when the use of such infrastructure requires wireless extension.  

    Therefore, one should focus on a proper Security Standards as well as solid secure construction. There are a vast variety of malicious attacks against mobile Ad hoc networks. In order to distinguish these attacks some classifications (attack models) are presented. Different malicious techniques against communications of the network are discussed in order to introduce the best practice, to set-up and maintain a secure mobile Ad hoc network. In this paper a solid intrusion detection system for MANET presented along with the best solution for creates a trust relation among nodes. Information gathering (Passive attack) is discussed from an ethical point of view.

    Kommunikation i bullrig miljö2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Kommunikation är viktigt i alla arbetssituationer som involverar mer än en individ. Vi tror teknologin hos tillverkarna av aktiva hörselkåpor har kommit ikapp med kraven som ställs på dom men helt enkelt glömts bort av industrin. Syftet med det här experimentet är att testa om de aktiva hörselkåporna kan skilja på allt bakgrundsljud som finns i ett maskinrum och samtalsljud från en annan människa. Experiementet tar plats först i ett maskinrum ombord på Calmare Nyckel för att mäta upp referensvärden sedan därefter i maskinsimulatorn. Testerna ombord på Calmare Nyckel och i simulatorn fick liknande resultat vilket bevisar att det inte spelar någon roll om ljudet kommer från en maskin eller en högtalare. Resultatet av experimentet visade att det inte spelar roll om ljudet kommer från en högtalare eller en maskin eftersom frekvensen vi pratar på var starkt representerad i båda fallen. Alla deltagare i experiment sa att dom inte kände någon märkbar förbättring av förståelsen genom medhörningen. Om något var hörselkåporna bara tyngre och större att ha på huvudet vilket uppfattas något negativt.

    Estimating the number of people in an area: Using Bluetooth and WiFi signals2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this world of the digital era, a large percentage of the world population and almost everyone in Sweden today owns a smartphone, and possibly even a smartwatch. By using this to our advantage, it would be possible to check whether an area is currently very busy or not, based on how many smartphones or other wearables technology it is possible to discover in the area. The approach chosen to dig into this problem was to research suitable hardware devices with Bluetooth and WiFi compatibility, that could detect probe requests broadcasted by smartphones or wearable devices in the area. The knowledge gained from the research in this thesis set the foundation for implementing a prototype with the desired functionality. Testing of the prototype was then conducted in a university library and analysed how it performed. Through testing the developed prototype, it revealed that it is possible to obtain an indication of whether an area is currently very crowded or not using Bluetooth and WiFi signals. A suggestion on how to proceed in creating more fine-tuned improvements is also described.

    ISIS – Information principles, skills, relations and capabilities for an inclusive learning society: -2012Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In our complex world of today we see that the leader- and followership is getting harder and harder to “command and control” our organizations and our society. The awareness of the decision makers are often too fragmented in relation to the often complex real situations out there. The information is only flowing in organizational stovepipes and not across boundaries as it should today. The patterns of mutual complex dependencies have taken over and we have difficulties in controlling the consequences of our decisions. The relations over organizational borders are often weak and fragmented and the mutual trust is low. Technology has always been a driver for the society to evolve and our idea is that technology can be the main driver for evolving cross boundary collaboration in order to meet the demands of the world. Technology can be the main driver but only if we consider all of the important dimensions when implementing Information and communication technologies (ICT)

    In order to find the right method of using technology and scientific methods for achieving better cross boundary collaboration a number of data collection activities has been performed, described and analyzed in the work with this thesis. The activities has been diverse in its nature, brainstorming activities, qualitative interviews and a small case study has been combined in order to derive the result – a path forward against further research for a better cross boundary collaboration in our western community.

    The thesis now have identified a path forward and a scientific framework for taking all of our experiences, existing capabilities, earlier performed research one step further and lift it up to the cross boundary level in organizations and in our society. We have the chance of cultivating all of the properties, relations, amounts of information, and evolve our technology. This may be all that we need in order to achieve a more socially sustainable climate in leader- and followership in our organizations and society.

    Who knows … maybe we can change the world … or at least make a real difference somewhere!

    e-Prescriptions: Privacy concerns and security risks in Greece’s e-Health care system2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The present thesis presents an informed by ethnography research that seeks to explore the privacy concerns and security risks that individuals perceive with regards to the electronic system of handling digital prescriptions. The research takes place in Athens, Greece and the participants are professionals who use daily the e-prescription platform and citizens whose data is being gathered and accessed. The paradiagm within which the research is unfolded is the interpretive one and a methodology of flexible design is followed. Thematic analysis of concepts produced by the data gathered is followed in order to offer an understanding of the concerns that the participants perceive. The methods that were used were interviews with professionals, focus groups with groups of citizens, individual interviews with citizens, observations and thinking aloud in pharmacies. The aim of the thesis is to illuminate those concerns with the aspiration that it be used as a basis for further research on the important issue of privacy of sensitive, medical data and suggest ways that could help ameliorate the identified concerns.

    Dynamic media distribution in ad-hoc social networks2012In: 2012 Second International Conference on Cloud and Green Computing (CGC), IEEE, 2012, p. 549-556Conference paper (Refereed)
    Abstract [en]

    This paper proposes a social distribution mechanism for finding, connecting and propagating contents in social networks using context and communication history of users together with meta information about the content. The proposed mechanism operates by propagating invitation messages to a prioritized group of users to build up an ad-hoc social network from the original social network while at the same time preventing spamming the users with unwanted invitation messages. The proposed mechanism makes it possible to implement and deploy a wide variety of services targeting the specific needs of a user. As a proof-of-concept, the paper shows how the proposed social distribution mechanism can be used to invite users to a shared space, which can contain various kinds of collaboration tools allowing a group of users to communicate and solve problems together. In order to investigate the efficiency of the proposed mechanism, the paper also presents result from a simulation study. The result shows that the social distribution mechanism should consider both social strength and context for propagating social media contents as some of the recipients may have equal interest of the social media but different level of trust about the originator.

    Supporting ubiquitous interaction in dynamic shared spaces through automatic group formation based on social context2012In: International Conference on Social Informatics (Social Informatics), Lausanne: IEEE, 2012, p. 121-130Conference paper (Refereed)
    Abstract [en]

    This paper investigates how the management of groups that communicate electronically, such as group formation, can be simplified based on users' context and social relations. This work builds on a framework for Aggregated Social Graphs, where each node represents the relational strength to other users. The strength of a relation is calculated by utilizing information on how we communicate using mobile phone calls, emails, and social networks in combination with additional sources of information such as from calendars. A contextual group management schema is presented where contextual parameters such as tags, locations and objects are used to prune an aggregated social graph in order to automatically form a group. The schema is implemented in a runtime environment based on the Distributed Shared Memory service available at Ericsson Labs. The feasibility of the proposed schema is then studied through a prototype implementation both in a web-browser and as a mobile app. The study shows that a group can be formed automatically and that a lightweight communication session then can be initiated for that group.

    Internal Communication: A quantitative case study at Specma Seals AB2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    BACKGROUND: Choosing the right communication strategy is essential for

    organizations in today’s business. Nowadays, all organizations

    are facing operational changes; therefore, internal

    communication is significant for all businesses. Internal

    communication focuses on information and knowledge sharing

    activities within organizations, which are led by leaders that

    have the responsibility to distribute information and knowledge

    to employees in the organization and across departments

    PURPOSE: The purpose of the study is to investigate the relationship

    between internal communication and its components and how

    it affects team performance.

    METHOD: The research was a quantitative case study where 42 out of 70

    employees at Specma Seals AB answered the questionnaire.

    The survey was sent out by email, using surveygizmo.com in

    April 2014. The response rate was 60%. A meeting with Specma

    Seals was arranged to conduct a deeper understanding of the

    company situation.

    CONCLUSION: The conclusion of this study is that two of the hypotheses were

    supported and one rejected meaning that leadership and

    information and knowledge sharing has a positive relationship

    with team performance meanwhile cross-functionality didn’t.

    User-Centric Social Interaction for Digital Cities2013In: Creating Personal, Social, and Urban Awareness through Pervasive Computing / [ed] Bin Guo, Daniele Riboni and Peizhao Hu, IGI Global, 2013, p. 318-346Chapter in book (Refereed)
    Abstract [en]

    Pervasive Computing was envisioned by pioneers like Mark Weiser, but has yet to become an everyday technology in our society. The recent advances regarding Internet of Things, social computing and mobile access technologies however converge to make pervasive computing truly ubiquitous. The key challenge is however to make simple and robust solutions for normal users, which shifts the focus from complex platforms involving machine learning and artificial intelligence to more hands on construction of services that are tailored or personalized for individual users.This chapter therefore discusses Internet of Things together with Social Computing as a basis for components that users in a ’digital city’ could utilize to make their daily life better, safer, etc. A novel environment for user-created services, such as social apps, is presented as a possible solution for this. The vision is that anyone could make simple service based on Internet-enabled devices (Internet of Things) and encapsulated digital resources such as Open Data, which also can have social aspects embedded.This chapter also aims to identify trends, challenges and recommendations in regard of Social Interaction for Digital Cities. This work will help expose future themes with high innovation and business potential based on a timeframe roughly 15 years ahead of now. The purpose is to create a common outlook on the future of information and communication technologies (ICT) based on the extrapolation of current trends and ongoing research efforts.

    Enhanced e-Learning Experience by Pushing the Limits of Semantic Web Technologies2014In: Proceedings of the 3rd International Workshop on Ordering and Reasoning Co-located with the 13th International Semantic Web Conference (ISWC 2014): Riva del Garda, Italy, October 20th, 2014 / [ed] Irene Celino, Oscar Corcho, Daniele Dell'Aglio, Emanuele Della Valle, Markus Krötzsch, Stefan Schlobach, Italy: CEUR-WS , 2014, p. 23-34Conference paper (Refereed)
    Abstract [en]

    We investigate a novel approach to e-Learning using Seman-tic Web technologies and aiming to optimise the learners’ experience incorporating pedagogical strategies into the learning process. The in-creasing availability of Semantic Web based educational resources and the establishment of open metadata standards like IEEE LOM pave the way for enhanced e-Learning systems that support personalised learning based on a reasoning framework and formal ontologies. We use ontologies to describe learning objects and the learner state, and define pedagogi-cal recommendation axioms that specify which learning objects are best suited for the learner in a specific situation. Recent pedagogical findings suggest that the individual learning can be optimised by means of guid-ance through learning pathways, i. e., a particular order in which learning objects are to be studied. To this end, we offer an OWL model for learn-ing pathways as structured sequences. We show the strengths and limits of OWL and propose a solution to overcome problems such as handling of soft constraints and ranking of result sets. The calculation for ranking is based on individual weights for specific learner-related features and considers the degree of match between learning objects and learner’s needs. The feasibility of our approach is shown by modelling real-life course material, i.e. a complete course on the Philosophy of Didactics. We implemented our approach as a prototype system and interfaced it to a standard Learning Management System.
