    Microsoft Windows Server 2008 Terminal Services vs. Citrix XenApp2008Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den här rapporten undersöker om gränsen mellan Terminal Services och Citrix XenApp har börjat suddas ut eller om man ännu kan dra en tydlig linje mellan dessa. Detta för att avgöra om organisationer som idag kör Windows Server 2003 med Citrix XenApp enbart klarar sig med de nya funktionerna i Windows Server 2008 Terminal Services och ändå uppfylla de krav och behov en organisation har. Arbetet genomfördes rent teoretiskt. För att avgöra likheter och skillnader mellan applikationerna, så användes till största delen ett ramverk. För att kunna få en bild av hur applikationerna tillämpas rent praktiskt, användes tidigare testar samt analyser. Resultatet visar att Terminal Services tagit ett större steg inom marknaden för applikationsvirtualisering. Slutsatsen antyder att Windows Server 2008 Terminal Services är lämplig för organisationer utan komplexa behov.

    WBD – Web Based Diagnostics: Identifierande av parametrar på CAN-bussen2007Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This abstract describes the bachelor degree thesis in computer technology at Växjö University written by Philip Albertson during the spring term of 2007. At the company BSR in Växjö, Sweden there is a new project under development called WBD – Web based diagnostics. The aim of the project is to make car diagnostics available to ordinary people at a decent cost. The system consists of three parts; a module to plug in the car, a server to handle the information and a client to allow the customers to reach the information about their car. My part in this project was to specify how to reach certain parameters on the CAN-bus in cars from VAG (Volkswagen Auto Group) and Saab. The company was satisfied with the results since they provided a good basis to further develop the module prototype built by the company EDAB (Elektronik Design AB) in Sundsvall, Sweden.

    Displayintegrering2010Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This abstract describes the Bachelor of Science in engineering thesis for computer science at Linnaeus University. Arcoma AB in Växjö is a company that constructs and develops complete x-ray systems. The goal of the company is to improve the usability of the system with the help of a LED display. Arcoma can improve the system by exchange the unit that controls the x-ray generator with the LED display instead. This will give the user the ability to have better overview and control of the system, while treating the patient.

    This report describes the implementation of both the software and the hardware for the display, but also the technical background for some standards like HDMI and the LED technologic. The software has been tested directly to the display, and therefore made the testing interesting. We have used the Arcoma system and the development tools to solve the problem. The programming language that was used to solve the problem was mainly C++.

    The result was a system that is build up by the Arcoma hardware platform, our surrounding electronics and the display where the last ones were built in a box. Aside the display a demo application was developed for controlling the generator. This applications is controlled by a USB mouse. Arcoma is pleased with the result of the main problem with the display, and they are also pleased with us solving the additional problems that existed. Arcoma wants to create a demand of this solution in their new products.

    A Matrix-Vector Operation-Based Numerical Solution Method for Linear m-th Order Ordinary Differential Equations: Application to Engineering Problems2013In: Advances in Applied Mathematics and Mechanics, ISSN 2070-0733, E-ISSN 2075-1354, Vol. 5, no 3, p. 269-308Article in journal (Refereed)
    Abstract [en]

    Many problems in engineering sciences can be described by linear, inhomogeneous, m-th order ordinary differential equations (ODEs) with variable coefficients. For this wide class of problems, we here present a new, simple, flexible, and robust solution method, based on piecewise exact integration of local approximation polynomials as well as on averaging local integrals. The method is designed for modern mathematical software providing efficient environments for numerical matrix-vector operation-based calculus. Based on cubic approximation polynomials, the presented method can be expected to perform (i) similar to the Runge-Kutta method, when applied to stiff initial value problems, and (ii) significantly better than the finite difference method, when applied to boundary value problems. Therefore, we use the presented method for the analysis of engineering problems including the oscillation of a modulated torsional spring pendulum, steady-state heat transfer through a cooling web, and the structural analysis of a slender tower based on second-order beam theory. Related convergence studies provide insight into the satisfying characteristics of the proposed solution scheme.

    Piqtura – Interaktiv bildvisning2008Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [en]

    The underlying question for this project was, how do you create a solid platform for art on the internet and how do you visualize the art in a good way?

    The technology used during the project was ASP.NET 3.5 with the programming language C#. To handle the datastorage MsSql Server 2005 was choosen. Plenty of time and effort was spent around AJAX and the creation of own AJAX Extenders, mainly for the imageviewing part.

    ImageGallery is a AJAX Extender that works like a simplyfied imagegallery, its used to visualize the artworks in a interactive way.

    The project resulted in a ready to use application targeted for artists that want to publish their works online. Visitors can affect the imageviewing in a interactive way. Other functions that are available to them are the possiblity to comment, rate and filter artworks. The administrators for the website can handle news, users, categories and techniques.

    Licenshantering: - Är företag medvetna om sin licenshanteringssituation?2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In a community where copyright and intellectual property law is getting more attention in the media, it is important for companies to be aware of their possession of software licenses. In this thesis we are going to investigate the awareness of the software licensing situation in some companies. To collect data that can be analyzed, we are interviewing companies. The interviews are performed by phone or e-mail. A similar report hasn’t been done before therefore it’s an interesting subject to look at.

    The interviews resulted in answers from 11 companies. The answers showed that the awareness about software licensing among the companies had big variations. Some other things that varied among the companies were the size of the companies and the usage of software licensing policy within the companies. The way and method of handling software licensing also varied among the companies.

    A lot of software programs, along with folders and Excel-lists dominated the method of handling software licenses among the companies. Software developing companies together with their interest organization for example BSA has demands on companies using their software to have a foreseeable documentation for the software licenses. They gladly see that the companies uses a best practice method to manage their license possessions, one best practice method is Software Asset Management, SAM.

    It is hard to recommend a method for software license management to a non-specific company, because every company has a unique organization and computer network structure. Most of the big license management software is following a best practice method for software license management.

    Abstract [en]

    Electrolux Laundry Systems in Ljungby gave us the commission to develop an embedded control system for functional adaptation. In that moment when the task was assigned there already was a fully functional system, but it was developed in such haste with the fact that it was not completely reliable. The system consisted of an ordinary desktop PC along with Windows XP as operating system and a program for functional adaptations written in Delphi. The problem of using this solution was principally the need of constant reboots, as a result of the operating system collecting rubbish values. Electrolux Laundry Systems desire was to replace their control system with a more industrial solution to improve stability.

    Abstract [en]

    In this project we examine the possibility to create a machine activity sensor by

    a one-chip computer that measures a machines vibrations through an

    accelerometer. The sensor shall generate a status signal. The accelerometer is

    used to give a measurable signal of a machines vibrations. The one-chip

    computer is used to sampel, transform and analyze this signal and generate a

    status signal. With LabView we can save, study and analyze different signals

    and their different transforms. By studying machine vibrations in LabView we

    decide that sampling at 5 kHz is sufficient. By comparing different

    transformations in regards to performance and calculation needs we choose

    Fast Fourier Transform as analyzing tool. We calculate that a ARM

    SAM7S256 can manage the task and implement an interrupt based sampling,

    frequency analysis and decision making routine which results in a status signal.

    Single Shot Shape Evaluation Using Dual-Wavelength Holographic Reconstructions and Regularization2013In: Fringe 2013: 7th International Workshop on Advanced Optical Imaging and Metrology / [ed] Wolfgang Osten, Springer, 2013, p. 103-108Conference paper (Refereed)
    Abstract [en]

    The aim of this work is to evaluate the shape of a free form object using single shot digital holography. The digital holography results in a gradient field and wrapped phase maps representing the shape of the object. The task is then to find a surface representation from this data which is an inverse problem. To solve this inverse problem we are using regularization with additional shape information from the CAD-model of the measured object.

    Time series analysis and forecasting: Application to the Swedish Power Grid2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    n the electrical power grid, the power load is not constant but continuouslychanging. This depends on many different factors, among which the habits of theconsumers, the yearly seasons and the hour of the day. The continuous change inenergy consumption requires the power grid to be flexible. If the energy provided bygenerators is lower than the demand, this is usually compensated by using renewablepower sources or stored energy until the power generators have adapted to the newdemand. However, if buffers are depleted the output may not meet the demandedpower and could cause power outages. The currently adopted practice in the indus-try is based on configuring the grid depending on some expected power draw. Thisanalysis is usually performed at a high level and provide only some basic load aggre-gate as an output. In this thesis, we aim at investigating techniques that are able topredict the behaviour of loads with fine-grained precision. These techniques couldbe used as predictors to dynamically adapt the grid at run time. We have investigatedthe field of time series forecasting and evaluated and compared different techniquesusing a real data set of the load of the Swedish power grid recorded hourly throughyears. In particular, we have compared the traditional ARIMA models to a neuralnetwork and a long short-term memory (LSTM) model to see which of these tech-niques had the lowest forecasting error in our scenario. Our results show that theLSTM model outperformed the other tested models with an average error of 6,1%.

    REGTEST - an Automatic & Adaptive GUI Regression Testing Tool.2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Software testing is something that is very common and is done to increase the quality of and confidence in a software. In this report, an idea is proposed to create a software for GUI regression testing which uses image recognition to perform steps from test cases. The problem that exists with such a solution is that if a GUI has had changes made to it, then many test cases might break. For this reason, REGTEST was created which is a GUI regression testing tool that is able to handle one type of change that has been made to the GUI component, such as a change in color, shape, location or text. This type of solution is interesting because setting up tests with such a tool can be very fast and easy, but one previously big drawback of using image recognition for GUI testing is that it has not been able to handle changes well. It can be compared to tools that use IDs to perform a test where the actual visualization of a GUI component does not matter; It only matters that the ID stays the same; however, when using such tools, it either requires underlying knowledge of the GUI component naming conventions or the use of tools which automatically constructs XPath queries for the components. To verify that REGTEST can work as well as existing tools a comparison was made against two professional tools called Ranorex and Kantu. In those tests, REGTEST proved very successful and performed close to, or better than the other software.

    Grön IT: Energibesparingar i datacenters med fokus på bladteknik, virtualisering och kylning2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [sv]

    Rapporten syftar till att titta på lösningar som kan ge minskade energikostnader i datacenters, med fokus på bladservrar, virtualisering och kylning. Vi undersöker hur man skulle kunna spara in på energin genom användandet av de olika teknikerna. Resultaten pekar på att bladservrar minskar strömförbrukningen jämfört med en motsvarande rackserver, samtidigt som virtualisering radikalt kan minska strömförbrukningen då man får ner antalet fysiska servrar. Även kylningen spelar stor roll när man ser till vad som förbrukar mest energi i datacentret. En hel del åtgärder finns att vidta för att effektivisera kylningen för att både få ner strömförbrukningen men även för att bättre kunna kyla alla servrar. Genomförda tester både vad gäller bladservrar och virtualisering visar på att det finns fördelar att vinna med användandet av dessa båda tekniker.

    Generation, evaluation, and optimisation of procedural 2D tile-based maps in turn-based tactical video games2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In modern times, procedural content generation sees frequent use in video games, producing anything from graphics to maps and quests. This study focuses on how these techniques can be used to produce forest maps for tactical role-playing games, and how this is applied in particular to Starshard, one such game. The main points addressed are how well the forestry growth simulation algorithm previously implemented in Starshard compares to algorithms based on other popular techniques, how to utilise evaluation and optimisation to produce correct and strategically interesting maps without human interference, and whether or not players can easily perceive a difference between procedural maps and maps designed by humans. With high demand for new algorithms to automate content generation in order to help smaller teams of developers and maintain interest in content post release, there is much value in delving further into less frequently explored aspects such as tile-based maps or player perception of procedural content. In order to answer the research problems, a controlled experiment comparing four forestry generation algorithms was performed, in addition to a study of literature to implement evaluation and optimisation algorithms, and a survey to gauge player reactions to the produced maps. Ultimately, the growth simulation proves to be more successful than alternative algorithms in reducing number of errors in maps. In addition, the results of the survey showed that while players are capable of reliably picking out human created maps, their ratings for procedurally generated maps were not much lower than these and they could frequently mistake procedural maps as being produced by humans.

    Implementering av dubbla CANbus i CANopen2008Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Hydroware Elevation Technology AB är ett företag som utvecklar styrsystem till hydrauliska hissar. Hårdvaran i detta system börjar bli gammal och går troligen ur produktion inom en snar framtid. EU har dessutom upprättat nya säkerhetsföreskrifter för installation av hissar där styrsystemet omnämns. I en grupp av hissar skall hisskorgarna isoleras från eventuella fel i övriga hissar. Med detta i åtanke har man inlett en förstudie där man tittar på ny hårdvara. Den nya hårdvaran har bland annat stöd för dubbla kommunikationsbussar, de bussar som styrsystemet använder för att kommunicera med samtlig styrelektronik.

    Detta examensarbete går djupare in på teorin bakom kommunikationsbussen CANbus och kommunikationsprotokollet CANopen. En idé för hur styrprotokollet kan modifieras för att stödja de dubbla bussarna presenteras. Presentationen följs av en beskrivning av implementeringen och testningen av modifikationen.

    This essay is about the networkfilesystem protocols SMB/CIFS, SMB2 and NFSv3. The work is based on the article ”A New Network File System is Born: Comparison of SMB2, CIFS, and NFS” which is written by Steven M. French at IBM, Samba Team. In the article there are no performance tests, we found it relevant to do performance tests to see which networkfilesystem protocol was the fastest with different filesizes in a Windows client environment. These tests were performed between two Dell PowerEdge 2900 servers where one of them was acting client and the other one fileserver. The tests were done once without network latency and once with. This resulted in that we got differences in how fast the protocols were with and without network latency.

    PeopleFinder - En Silverlight webbapplikation2010Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This abstract describes the Bachelor of Science in engineering thesis for computer science at Linnaeus University. Växjö municipality are at the moment in the middle of a new project where they are trying to gather the entire IT-organization into one to make the service for the employees and the citizens better. This project is called “one IT” and will gather the IT-organization into four main departments; Servicedesk, Service, System and Development.

    Because of these changes there has been a request for an easier way to search for information about people within the IT-organization. Today you can find information about the employees in several different programs and the goal is to create an application where you can find all the wanted information like phone number, area of competence, status (at a meeting, at vacation) etc. at one place.

    The result of our examination thesis is a working application which we call PeopleFinder and are created in Silverlight where you can search for people, see a picture, name, contacts, location (geographically and where their office is in the building) and some other information that might be of interest. This has been developed after the requests of the IT-manager and other involved from the IT-organization, and was finally presented to the entire IT-organization.

The work is performed with literature studies and a survey of a dozen smaller companies, and also a laboratory environment where properties of the different remote access solutions are performed.

    This area was chosen because the subject of remote access scarcely was treated during our education, and become engrossed in this area.

    The result shows what the companies consider to be the most important properties with a remote access and also the products results from the tests. Also the values that occurred during testing in a laboratory environment will be presented in the results. The combined results will then show which software-based solution that is best suited for a small company.

    Inter-organisatorisk kommunikationssäkerhet: En fallstudie av informationssäkerhetsarbetet runt e-recept2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [sv]

    Samtidigt som användandet av e-recept ökar i Sverige har Datainspektionen vid en tillsyn hos Apoteket AB konstaterat att det, i samband med överföringen av e-recept från vissa vårdgivare till Apoteket, finns brister i personuppgiftshanteringen. Hur uppstod dessa brister och finns det något de inblandade organisationerna kan göra för att undvika att liknande situationer uppstår i framtiden?

    Arbetet behandlar hanteringen av kommunikationssäkerhetsproblematik i ett inter-organisatoriskt perspektiv och beskriver hur det övergripande informationssäkerhetsarbetet påverkats av olika aktörers syn på ansvarsfrågor. Arbetet har sin utgångspunkt i en kvalitativ fallstudie där hanteringen av e-recept mellan Kalmar läns landsting och Apoteket AB står i fokus. Representanter från Apoteket AB, Kalmar läns landsting, Datainspektionen och Sjukvårdsrådgivningen SVR AB intervjuats i ett försök att beskriva, förstå och förklara de olika organisationernas syn på e-recept, dess kommunikationskanaler och kommunikationssäkerhetsansvaret vid överföring av elektroniska förskrivningar. Målet är att med hjälp av denna kunskap skapa ny förståelse för hur kommunikationssäkerhetsbrister kan uppstå i inter-organisatoriska sammanhang. 

    Som grund för diskussionen presenteras teoretiska aspekter på det svenska systemet för e-recept, följt av en vårdjuridisk översikt samt teorier inom informationssäkerhetsområdet. Studien visar att de grundläggande förutsättningarna för en fungerande inter-organisatorisk kommunikation finns men att aktörerna haft svårt att hitta lämpliga verktyg för att koordinera ansvarsfrågor. 

    Nyckelord: kommunikationssäkerhet, inter-organisatorisk samverkan, e-recept, informationssäkerhet, hälsoinformatik.

    Model Driven Architecture in Adaptive Library Generation2008Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This master thesis is about building an adaptive library based on a platform independent model, which represents a conceptual design realizing the functional requirements being independent of the technologies and software architectures changes.

    This adaptive library is a model, which has a higher level of abstraction than the code that we will generate afterwards, generalizes the solution of those problems that can be resolved using different implementations that uses different kinds of data structures.

    In addition the higher level of abstraction that this adaptive library is having will give a speed up in developing the application and higher quality solution because of the maintainability and reusability. This solution is going to have the propriety to be changed easily in order to solve different concrete problems.

    Separation and Extraction of Valuable Information From Digital Receipts Using Google Cloud Vision OCR.2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Automatization is a desirable feature in many business areas. Manually extracting information from a physical object such as a receipt is something that can be automated to save resources for a company or a private person. In this paper the process will be described of combining an already existing OCR engine with a developed python script to achieve data extraction of valuable information from a digital image of a receipt. Values such as VAT, VAT%, date, total-, gross-, and net-cost; will be considered as valuable information. This is a feature that has already been implemented in existing applications. However, the company that I have done this project for are interested in creating their own version. This project is an experiment to see if it is possible to implement such an application using restricted resources. To develop a program that can extract the information mentioned above. In this paper you will be guided though the process of the development of the program. As well as indulging in the mindset, findings and the steps taken to overcome the problems encountered along the way. The program achieved a success rate of 86.6% in extracting the most valuable information: total cost, VAT% and date from a set of 53 receipts originated from 34 separate establishments.

    Utveckling av e-handel med ASP.NET AJAX2008Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Tekniknummer_579

    This report discusses the development of a web-based e-commerce solution where new technologies for development are applied. Different techniques for creating a richer and more interactive user interface are applied.

    How do you develop an e-commerce website with today’s modern techniques? Which technologies are best suited? Questions like these are the basis for this graduation work and we have been given an assignment by a company called Mil Tech situated in Västerås, to develop an e-commerce website with card-payment and also with an administration interface.

    The purpose with this graduation work is in part to find out how you develop an e-commerce website with today’s modern technologies, which technologies are best suited for the task and to adapt the site according to the customers wishes and demands. This will be done by developing an application where the customer can handle products and update the websites information and appearance. A user shall be able to register and carry out a purchase.

    The application is developed in ASP.NET 2.0 with the developing language C-Sharp (C#). This is a relatively new technique with high security and performance, and also that it has good compatibility with the powerful database-handler MS SQL Server 2005. In addition to C# the application also uses ASP.NET AJAX Extensions.

    Our developing environment is made up of Visual Studio 2005 Professional with version handling through Subversion and database handling through MS SQL Server 2005 Express and MS SQL Server Management studio Express.

    To get the information we need for the project, the main source will be the Internet, because we need current information and today literature isn’t always up to date.

    Preparations we did before developing were to gather information about e-commerce with card-payment, and going through the customers wishes and demands.

    The entire website except the administration is language-dependent and can be viewed in three different languages, Swedish, English and German.

    Kamerakalibrering2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Saab has developed a product, Remote Tower, which is designed to remotely control an airport that is monitored and controlled from a location other than the air traffic control tower. At the airport you want to control the cameras mounted in a manner such that a 360 degree view is given and the image of those sent to the place from which to control the airport. When a re-installation of one or many cameras is needed there is today required two people. These may have to work in different places because the server does not need to be located in the vicinity of the airport itself. This is both time consuming and costly, which has led to a need for a versatile installation of the cameras. A server application has been developed which can communicate with the cameras and control their functions such as zoom, focus and iris, but also make image comparison calculations. An Android application was also developed to access the server. It is this that the installer will use when he is up in the camera tower and adjusts the cameras. This application has access to the current view, the camera's features and also the possibility to run guides created to facilitate calibration.

    BSR Diagnosverktyg – Kommunikation över CAN och K-line bussen2008Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This abstract describes the bachelor degree thesis in computer technology at Växjö University. At the company BSR in Växjö, Sweden there is a new project under development called BSR Diagnostic Tool. The main idea is to use a hardware class for communication instead of the diagnostic tools that are provided by the car manufactures. In object-oriented programming, a class is a programming language construct that is used as a blueprint to create objects. The task was to implement this hardware class which will handle the communication between a computer and the control units in the vehicles. The report also includes a big theoretical part about the communication bus that is used, CAN. The objective was to create the class and make it communicate successfully with a Saab. The testing of the class was done with a simple program. The program can send a question to the vehicle and retrieve an answer with help of the hardware class. BSR provided a diagram with functions that should be present. The development of the system was done using C# and .NET Environment. The company was satisfied with the results since they provided a good basis to further development of BSR Diagnostic Tool.

    Visualization of spiral drawing data of patients with Parkinson's disease2014In: Information Visualisation (IV), 2014 18th International Conference on 16-18 July 2014, IEEE conference proceedings, 2014, p. 346-350Conference paper (Refereed)
    Abstract [en]

    Patients with Parkinson's disease (PD) need to be frequently monitored in order to assess their individual symptoms and treatment-related complications. Advances in technology have introduced telemedicine for patients in remote locations. However, data produced in such settings lack much information and are not easy to analyze or interpret compared to traditional, direct contact between the patient and clinician. Therefore, there is a need to present the data using visualization techniques in order to communicate in an understandable and objective manner to the clinician. This paper presents interaction and visualization approaches used to aid clinicians in the analysis of repeated measures of spirography of PD patients gathered by means of a telemetry touch screen device. The proposed approach enables clinicians to observe fine motor impairments and identify motor fluctuations of their patients while they perform the tests from their homes using the telemetry device.

    Abstract [sv]

    Detta arbete har genom experiment och tester undersökt förbättringspotentialen för en halvautomatisk grundtillsyn av Ra180. Eftersom att denna grundtillsyn tar lång tid är det högst relevant att försöka korta ner den. Genom noggranna mätningar som har testats har det tagits fram lämpliga lösningar för en påtaglig förbättring. I linje med detta har även en undersökning gjorts av huruvida en helautomatisk grundtillsyn är möjlig. Genom dessa undersökningar har också en hårdvaruprototyp till denna metod tagits fram och implementerats.

    Lokal Nätverkssäkerhet - experimentell studie av Microsoft Network Access Protection2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [sv]

    Den här rapporten beskriver en experimentell studie av Microsoft Network Protection (NAP) och är ämnad för att utvärdera hur mogen tekniken är för att implementeras i en aktiv nätverksmiljö. För att göra studien tog vi hjälp av gymnasieskolan John Bauer i Kalmar. Tester har utförts med DHCP-framtvingning och 802. 1x-framtvingning, dessa är två av NAPs fyra olika framtvingande funktioner. En mindre analys av skolans switchkonfigurationer och interna säkerhet har även gjorts på John Bauers begäran. Testerna har visat att DHCP-framtvingning är en bra och enkel lösning för John Bauers trådade klienter. NAP-funktionen 802. 1x- framtvingning var en större utmaning dock, och blev inte lyckad. Utbudet av information om NAP är än för knapphändig och vi anser därför att inte bara 802.1x framtvingning inte är redo för implementation, utan även framtvingning med DHCP.

    Möjligheterna med Jailbreak2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Detta arbete är en undersökning om vad en Jailbreaking av iPhone OS kan tillföra för en vanlig användare och även de utökade möjligheterna för utvecklare. Det syftar till att ge en lätt överskådlig förklaring om hur jailbreaking fungerar och vilka fördelar och nackdelar som följer med det valet.

    Det var ett personligt intresse för modifikation av operativsystem som gav grunden för valet av denna undersökning. Efter det egna införskaffandet av en iPhone 3Gs i slutet av 2009 utvecklades intresset för jailbreaking, något som successivt byggdes upp till en passion att vilja undersöka en iPhones fulla potential.

    I rapporten kommer ett antal jämförelser att göras mellan ett native iPhone OS och ett Jailbreakat iPhone OS. Versionen är 3.1.3, vilken är den senaste stabila. Det presenteras viktiga paket som bevis för vad de extra funktioner som kan uppnås genom användandet av jailbreak. Det kommer även att beskrivas hur Jailbreak utförs. De paket som presenteras i arbetet kommer att vara de mest populära, funktionsrika och pålitliga utav de som finns tillgängliga inom jailbreak communityn.

    Detta arbete resulterade i en redan förväntad bekräftelse att jailbreak har mycket att tillföra både normalanvändare för att utnyttja sin enhet med iPhone OS till sin fulla potential, men även för utvecklare som blivit nekade av Apple att få sälja sina produkter på AppStore eller helt enkelt bara vill utveckla utan Apples restriktioner och regler. Pengar finns absolut att tjäna genom Cydia Store eller liknade, vilket bevisas genom statistik och estimeringar.

    API development to improve integration and resource efficiency.: Decreasing user interactions and automating verification processes of information between applications.2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Companies today often have a variety of applications used in the daily work. The problem that companies face with these applications is that they often are brought in to deal with a specific task, and they are often brought in at different times by different third-party developers. This results in the applications being independent units and integrates poor with each other, making work and maintenance with the applications inefficient. To improve efficiency the applications need better integration with each other. Better integration can be achieved by either replacing the current applications with a new software or develop a software that helps the applications communicate.

    This project covers the development of the later, an API to improve the efficiency at Volvo Construction Equipment in Braa ̊s. The API is developed with the Enterprise Service Bus (ESB) as inspiration. The purpose of the ESB is to act as a middleware for the applications. Due to time limitations for the project integration between the applications wasn’t achieved. Instead, the focus was set on improving one of the moments in the work process at Volvo, that is verifying information between applications. The verification is today done manually which makes it time-consuming and this is the API set out to deal with. The API results in a reduction and improvement regarding the verification. The API still needs a manual input of data from the applications, but the API has automated the verification of the information between the applications resulting in hours of reduced work for the staff at Volvo.

    Abstract [en]

    Svenskt Rockarkiv is an organization located in Hultsfred, Sweden. Its goal is to collect and document the history of Swedish rock music. The archive contains several types of documentation, such as audio recordings, photographs, posters, video recordings and books representing Swedish rock music history. In order to store information about the audio recordings in the archive, Svenskt Rockarkiv uses a SQL Server 2000 database and a client application written in Microsoft.NET C# and Windows Forms. The purpose of this degree project is to audit the database and windows client, since the organization has needs of new functionality. There are also some bugs in the system that needs to be corrected. The result of the audit states that the database needs to be extended with additional tables and some structural changes to handle the new demands of the system. The poorly designed architecture of the windows client causes performance issues, and these issues are believed to increase with the size of the database. Based on the audit a suggestion of changes to the system is presented, with emphasis on overall performance, usability and preparations for future development. Structural changes to the database are presented as well as a new distributed client-server solution. By using the .NET Remoting technique the business logic is placed in a separate physical layer increasing performance and scalability, and making the system easy to extend with future functionality. Finally the outcome of the system development is presented with a database model and an implementation of the new client.

    Hoppsan! Gick det lite fort?: En studie om lärares förutsättningar vid införandet av programmering i läroplanen.2019Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I det här arbetet har en enkätundersökning genomförts för att undersöka de förutsättningar lärare haft vid införandet av programmering i läroplanen samt hur lärare upplevt förberedelserna inför förändringen. Enkäten besvarades av verksamma mellanstadielärare i en medelstor stad i södra Sverige. Datamaterialet analyserades därefter med utgångspunkt från tidigare forskning. Studiens resultat visar att den största andelen lärare som utbildat sig inom programmering har gjort det på eget initiativ. Det framgår att vissa lärare har fått möjligheten att utbilda sig genom sina arbetsplatser, medan andra fått göra det på sin egen fritid. Studien synliggör även lärares uppfattningar om det stöd de fått under införandet av programmering, vilket talar för att majoriteten av lärarna inte varit nöjda. Resultatet visar att lärarnas kunskaper om programmering hindrar dem från att bedriva en undervisning för alla elevers olika kunskapsnivåer.Studien bidrar således till att uppmärksamma lärares egna uppfattningar om deras kunskaper och undervisning om programmering. Rektorer och lärare kan därför, genom denna studie, bedöma om det behöver läggas mer fokus eller resurser på kompetensutveckling av lärare.

    Betalsystem för Inteli3 GSM roaming plattform2007Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Vår uppgift är att sammansätta en produkt som skall sänka de så kallade ”Roaming”

    avgifterna som uppkommer då ett telefonsamtal måste resa eller ”roama” genom flera olika

    operatörers mobilnät. För att sänka denna kostnad har ett företag vid namn ”CallKey Group

    Ltd” tagit fram en produkt, ”CallKeyOne” som är en lösning baserat på GSM SIM-kort.

    CallKeyOne kommer att reducera kostnaden för utgående samtal radikalt och att motta samtal

    blir gratis i de flesta länder. Detta leder ofta till en reducerad kostnad med upp till 70 %.

    Uppgiften för författarna av denna rapport var att integrera CallKey: s API med en

    webbaserad betalsida vid namn PayNova. Den färdiga produkten ska bli en fullt fungerande

    produkt som tillåter kunderna att fylla på sitt SIM-kort med förbetald kredit för internationella

    samtal. Till uppgiften hör även att skapa en databas där information om överföringar och

    kunder skall lagras. Kunden ska kunna betala via kreditkort och pengarna ska sedan överföras

    till uppdragsgivarna. Uppgiften har utförts med hjälp av ByAir AB som är ett svenskt företag

    med kontor i Göteborg som har licensen för CallKeyOne i Sverige.

    Comparison between Native and Cross-Platform Apps2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The primary purpose of this study is to determine in which technology we have to

    develop an application depending on the features that we would like to include, in order

    to deliver the best value for a good price to the customers. Consequently, in this

    research we have described the capabilities, performance and limitations that we have

    found while using the different technologies. The empirical part of this study was

    conducted in the first semester of 2014/2015 at the Linnaeus University in Växjö

    (Sweden), supported by Softwerk Company.

    In conclusion, the thesis shows that the user experience with native apps is always better

    than using the web-based technologies, especially using maps, although the time and

    effort spent to develop them is higher. Cross-platform solutions can be very useful for

    simple apps, and also if the developer does not have a lot of time to develop them. The

    problem with this last kind of applications is that the performance is less than the native

    ones.

    Autostereoskopiska skärmar i moderna spel2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    3d-skärmar är en spännande teknik som har fått en ny vind på senaste tiden med artiklar som 3DeeShell till iPhone och Wazabees 3d-lösningar till PC.

    När dessa 3d-skärmar används till att visa spel i 3d så stöter spelutvecklare på problem när de ska utveckla visuella effekter såsom anti-aliasing och billboarding, då dessa tekniker kanske inte är anpassade till 3d-skärmens funktionalitet.

    Undersökningen i detta arbete söker att finna några svar på hur dessa tekniker fungerar tillsammans med dessa 3d-skärmar och det kommer att redogöras för några åtgärder för att förbättra kvalitéen på dessa visuella tekniker.

    Evaluation and Analysis of Hardware Sizing for a Mission Critical Enterprise Application2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Hardware sizing has come to play an important role when designing and implementing business critical applications because it is crucial that the existing or defined business and application requirements are interpreted into an appropriate hardware configuration. If it is not done correctly, it may destabilize the environment which means interruptions and unplanned downtimes that in turn will cause business loosing not only vital revenue but also customer confidence in the process. This is one of the reasons for why hardware sizing has become a discipline of its own and as such, each combination of workload and hardware configuration is treated differently. Many application vendors have their own set of tools and recommendations to perform the sizing. Once the sizing is performed, the results can be mapped to hardware that is already benchmarked. This also means the hardware can be configured specially to support the application workload in question. It also implies that sizing is one of the major activities when creating a technical architecture where it is used to select the right hardware.  

    The purpose of this document is to perform a complete sizing exercise based on the requirements for a mission critical business application and then translate them into an appropriate hardware configuration. Furthermore, a set of sizing methodologies and tools are analyzed in detail as well in order to give an as vendor neutral view as possible. Specific requirements such as high availability, scalability and other important areas are also taken into consideration when designing and creating the hardware architecture.

    Webbbaserad Givarservice Myrorna2008Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpStudent thesis
    Abstract [sv]

    Examensarbetet, 15 poäng har utförts på högskolan i Kalmar. Input Soft AB är ett företag som är beläget i Strängnäs. Uppdraget för projektarbetet bestod av att utforma en webbbaserad givarservice till Myrorna. Myrorna använder idag fleetIT som är ett program utvecklat av Input Soft AB för registrering/hämtning av gåvor till Myrorna. Denna webbaserade givarservice förenklar och effektiviserar arbetet för Myrorna genom att användarna själva går in via Internet och registrerar sina gåvor istället för som idag då registreringen sköts helt av personalen i Sätra. Teknikerna som använts är ASP-dotnet och en nexus databas som är integrerad med fleetIT Systemet. Server Applikationen kommer att ligga på Myrornas egen server och vara kopplat till fleetIT systemet.
