    Sveriges Optiska Fibernät -systemutveckling2001Självständigt arbete på grundnivå (kandidatexamen)Studentuppsats (Examensarbete)
    Abstract [sv]
    In association with Svenska Kraftnät, a large Swedish owner of fiber optical net, our bachelor thesis has been formed. To achieve a good error remedy, a thorough plan is necessary. Today, this is not to be found in all cases. Our assignment have been to present a specification for a central helpdesk for the fiber optical net. A database belonging to the helpdesk shall contain maps and fiber information. To reach a good result, we have compared the different systems that today exist among the big operators in Sweden. Along with our own ideas we have reached a result, wich we choose to present in a demonstration database. Fundamental facts about fiber optics are also included in the thesis. To achieve a common Swedish infrastructure we consider that a co-ordination of the error remedy for the different operators is essential. The helpdesk would function as a central part of the business and provide the fiber optical net good structure. The main task for this helpdesk should be to receive error reports, to give priority to errors and handle documentation along with co-ordination of the communication with contractors.

    Comparative analysis of the SVJJ and the Hyperbolic models on the Swedish market2008Självständigt arbete på avancerad nivå (magisterexamen), 40 poäng / 60 hpStudentuppsats (Examensarbete)
    Abstract [en]

    In this thesis we investigate and compare two recently developed models of the option valuation according to the Swedish market. The first model is the Stochastic Volatility model with jumps in the stock price and the volatility (SVJJ) and the second is the Hyperbolic model. First of all we make brief introduction about the valuation of derivatives and considered models. Then we introduce methods for the estimation of parameters for each model. To solve this problem for the SVJJ model we use the Empirical Characteristic Function Estimation and for the Hyperbolic we use the Maximum Likelihood Method. Before explicit calculations (with estimated parameters) we describe the derivation of the pricing formula which is based on characteristic functions and densities. In conclusion we made numerical valuations of the call option prices for the OMXS30 index on the Swedish Stock Exchange. The main idea of this thesis is to compare 2 different models using numerical methods and the real data sets. To achieve this goal we firstly, compare the empirical characteristic function obtained from the market and the analytical ones for estimated parameters in case of both models. Secondly, we make a comparison of calculated call option prices and produce the summary.

    Investigation of Metal-assisted Si Etching for Fabrication of Nanoimprint Lithography Stamps2010Självständigt arbete på avancerad nivå (magisterexamen), 15 poäng / 22,5 hpStudentuppsats (Examensarbete)
    Abstract [en]

    This diploma thesis deals with the investigation of the metal-assisted catalytic etching (MaCE) of Si. One of the main goals is to study fabrication of stamps for nanoimprint lithography using MaCE.

    Formation of nanoporous silicon (PSi), Si nanowires (SiNWs) and three-dimensional nanostructures in Si by MaCE is demonstrated. For this purpose optical lithography, electron beam lithography (EBL), shadow mask evaporation and aerosol nanoparticles deposition techniques have been utilized. The etching rate and surface morphology of Si (with Au lift-off films as a catalyst) as functions of time and concentrations of chemicals are measured in the current diploma work using optical microscope and scanning electron microscopy (SEM). In the current thesis it is shown that Si structures with sub-150 nm lateral sizes, high aspect ratio (up to 1:21), well-defined shapes, and various complexity can easily be fabricated by means of MaCE process.

    Medverka eller inte medverka: en studie av användarmedverkan inom ITiS-projektet2001Självständigt arbete på grundnivå (kandidatexamen)Studentuppsats (Examensarbete)
    Abstract [sv]
    Undersökning handlar om varför användare väljer att medverka eller inte medverka i ITiS-projekt samt om användarens identitet i organisationen påverkar medverkandet. Studien har genomförts på två skolor inom Vabergs kommun. Slutsatser som har dragits är att det inte finns några samband om användaren har medverkat i ITiS eller inte och vad personen har för ålder, kön eller vad respondenten arbetar som. Det finns en indikation att arbetslagets önskningar har en stor betydelse, men även att det till viss del kan vara frustrerande för den enskilde individen som önskar att få medverka. Postmoderna influenser som bl.a. handlar om förändringar avseende identitet och gränser, förändringar i förhållande till traditioner och vanor kan skönjas. Huruvida användaren är influerad, omedvetet, av postmodernismen eller inte mäts inte i denna studie.

    Grafiskt Programmeringsverktyg för DSP-robot2003Självständigt arbete på grundnivå (kandidatexamen)Studentuppsats (Examensarbete)
    Abstract [sv]
    Today Halmstad University is using six robots that are based on a digital signal processor (DSP) from Texas Instrument and an external I/O-card. These robots can today only be programmed by means of conventional programming, i.e. some kind of high level language as for example ANSI-C, which can be difficult for people with less programming skills. The idea of the robots is that they should be used to introduce and get high school students interested in this kind of technique, and that’s why it has to be easier and more intuitive to program them. This report explains how to construct a graphical programming tool, i.e. a tool that involves that the user can place a number of happenings on the screen that he/she wants the robot to perform. The user then links them together in what order he/she wants them to happen. After this the necessary code in ANSI-C is generated by the tool itself, i.e. the user can actually program the robot without really having any programming skill. The tool also automatically compiles, links the generated code, and creates a binary file, which later can be downloaded to the robot. The user can within the tool add, delete and move different objects (happenings), e.g. run engine 1 with a certain speed, read the value of digital and analog inputs etc. It is also possible to dynamically increase the functionality of the tool by simply adding new features, which is powerful if you for example want to use the tool on different robot platforms. The functionality is tested on a real robot equipped with two DC-engines and two digital sensors. The result shows that both the code generated by the program is correct as well as the generated binary file, i.e. the compiling, linking and downloading stages work correctly.

    Industrisymaskin med webbserver2003Självständigt arbete på grundnivå (kandidatexamen)Studentuppsats (Examensarbete)
    Abstract [sv]
    Today’s modern industry of machine production gets more and more spread worldwide. At the same time so are the products/machines. This could lead to problems when/if a product/machine stop working (for some reason). Then the producer has to send a technician to the customer for problem solving. For the producer this is both expensive and time consuming. If the producer had used (connected their products to the Internet) the Internet for their products, they could have used other methods for the problem solving. When you connect the product to the Internet you get the opportunity to talk to the machines all over the world. In that way you can supervise and steer machines around the world from one place. You can collect statistics from your machine and through that information develope better machine. You get better service for less cost. This degree project is made for Styrteknik Europe AB in Helsingborg who develops and manufactures industrial sewing machines and automatic systems, for sewing circles and cross seams in cushions, mattresses, pads, other filled materials and products. Their machines are sold worldwide. Our project has therefore focused on solutions to their products. The machines PLC are made by Beckhoff or Hitachi. Together with the company management we have chosen to concentrate on supervision of the PLC from Beckhoff. This degree rapport purpose is to show how we have developed a system for Styrteknik, whose task is to supervise a machine. The system contains one application who supervises the machine and this information is transferred over Internet to a database. Finally a homepage publishes the information from the machine.

    Combining the Good Things from Vehicle Networks and High-Performance Networks2007Självständigt arbete på avancerad nivå (magisterexamen)Studentuppsats (Examensarbete)
    Abstract [en]

    The aim of this Master’s thesis is to develop a solution for combining speed and performance of switched Ethernet with the real time capability and determinism of sophisticated in- vehicle networks. After thorough research in vehicle network standards, their demands and features, the

    Flexible Time Division Multiple Access (FTDMA) protocol of FlexRay was chosen to be applied on a switched Ethernet architecture since it can accommodate both hard real time tasks and soft real time tasks. To provide hard real time capability, what this paper focuses on, a media access method was developed by creating static TDMA schedules for each node’s sending and receiving

    port according to a certain traffic assumption. To validate the developed media access algorithm several examples with different traffic assumptions and architectures were generated and

    investigated based on their sending and receiving utilization. A second method for validating and thus proving the functionality of the algorithm was by simulation. Therefore the Matlab Simulink

    media library extension TRUE TIME was used to simulate a simple example with 100% sending and receiving utilization for each node.

    Design of a Software Application for Visualization of GPS and Vehicle Data2009Självständigt arbete på grundnivå (kandidatexamen)Studentuppsats (Examensarbete)
    Abstract [en]

    I present an application to visualization of GPS data and Linear Correlations and models. A collection of data for each vehicle is used to compute correlations. Deviating correlations can be indicative of a faulty vehicle.

    The correlation values for each vehicle are computed with use linear regression algorithms using up to 4 signals in the data (with varied time window), and display the model parameters in a window next to the GPS map. Multiple measurements (multiple drive routes and multiple model parameters) are displayed at the same time, allowing tracking over time and comparison of different vehicles.

    The whole technique is demonstrated on three data which is set on first frame by user. The results are displayed with a java application and Google Map.

    An Empirical Study to Observe Route Recoverability Performance of Routing Protocols in Real-Time Communication2009Självständigt arbete på avancerad nivå (magisterexamen)Studentuppsats (Examensarbete)
    Abstract [en]

    This thesis is an experimental study to evaluate the performance of different routing protocols in commonly deployed scenarios. This study mainly focuses on how much time each protocol consumes while recovering from a link-loss. It provides a guide line for the best routing solutions for ISPs, individual organizations or other types of providers which are engaged in providing reliable real-time communications to their subscribers. Such communications may include vehicle trafficking data, online TV programs (IPTV), voice over IP telephony (VoIP), weather forecasts, tracking systems and many other services which totally depend upon the reliability of real-time data streams, where any major loss in received data may bring significant negative results in the integrity of the entire application.

    This work experimentally observes and tracks the loss of UDP packets when changes in the network topology occur. In order to make this observation in real network topologies, a custom-designed software tool has been developed. The tool is capable of delivering enough resources to a tester in evaluating the performance of routing protocols. All the test results derived from the software tool are statistically evaluated and on the basis of the outcome a better proposition can be provided to network administrators which face inconsistent topological issues.

    Abstract [en]

    Wireless sensor networks offer easy implementation, flexibility and mobility of hand held

    devices. Sensors consist of an internal power source, which is the great limitation for

    the life time and the usage of sensor networks. To increase the life time, sensors should

    stay in energy saving sleep mode as long as possible, because in sleep mode the radio is

    either shut down or working with less energy. Better energy handling is implemented in

    different power saving mechanism of common Medium Access Control protocols, which are

    evaluated and analyzed and further extensions and ideas to improve the energy efficiency

    are presented. Slotted PSM is simulated with the NS2 and compared to the WLAN 802.11

    PSM technology and the results show that energy efficiency and power consumption are

    much better implemented and life time increases with the use of Slotted PSM.

    Nya lagar och avtal: Hur kan de komma att förändra svenskarnas fildelningsvanor?2012Självständigt arbete på grundnivå (högskoleexamen), 5 poäng / 7,5 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    I många år nu har det varit vanligt förekommande att människor suttit hemma vid sin dator och med några få klick laddat ner filmer, musik och programvaror, till en början helt lagligt, men med åren har lagar kommit till som har gjort det mer och mer olagligt.Oavsett om det har varit lagligt eller inte, så är det troligt att många artister, filmmakare och liknande gått miste om stora summor pengar i förlorade inkomster på grund av att folk inte har betalat för att ta del av deras verk, utan istället valt att ladda ner dem över Internet.

    Det faktum att fildelning har blivit så pass vanligt och att folk inte har sett det som ett särskilt allvarligt brott, har lett till att fildelning länge har varit ett hett omdiskuterat ämne i media, bland upphovsrättsinnehavare och bland folk i allmänhet. Upphovsmän och upphovsrättsinnehavare, såsom filmbolag, författare och artister har legat på och debatterat för att försöka få till en hårdare lagstiftning för att försvåra fildelning och kopiering av upphovsrättsskyddat material, samt för att få till hårdare straff mot fildelning.

    Flera försök från beslutsfattare har gjorts för att råda bot på problemet, nya lagar har stiftats och avtal har skrivits under. Frågan är om de nya lagarna och avtalen gör någon nytta? Blir folk avskräckta från att fildela eller fortsätter de som förut? Många har säkert under många år blivit bortskämda med att kunna sitta hemma vid datorn och på några minuter få hem de senaste filmerna och den nyaste musiken helt gratis, vilket säkert gör det svårt att helt plötsligt sluta fildela och börja betala för film och musik igen.

    PICKO, Friktionsfri principlösning för Pick and Place robot2004Självständigt arbete på grundnivå (kandidatexamen)Studentuppsats (Examensarbete)
    Abstract [sv]
    Picko is a project based on frictionless linear motors from LinMot, which have become less expensive over the last few years. To make them even more lucrative, the automation company SDT wants to bring the level of programming to the customer’s level. This will be done by adapting the current software from LinMot according to the PLCopen standard for controlled motions. To be able to demonstrate the possibilities with this kind of adaptation, SDT also requires a robot to be built. A function library was constructed in CodeSys according to the PLCopen standard. With this library, the customer only needs to write parameters in order to control the motors. A robot was also calculated and built with concentration on design The result is an application with two axes, which with the use of our function library, could easily be programmed to perform motions with high accelerations and velocities.

    Wireless Low Power Data Acquisition Device: Embedded design and application2012Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Embedded systems are utilized in various modern-day applications in order to ease routine tasks that are otherwise demanding in manpower; an example of which is data sensing and acquisition. Modern sensor applications usually involve one or more embedded microcomputer systems with inputs from various sensors and a means of connection to transmit the acquitted data to its point of interest. While many sensor and acquisition applications and standards exist for industrial use, the consumer/small business markets for such devices seem to be fairly bleak in comparison. In this project, various data communication standards for transmitting information between sensors and acquisition devices are investigated. Wired, such as RS232, I²C, SPI and 1-Wire, as well as wireless protocols like Wi-Fi and ZigBee were studied. Then, a generic wireless data acquisition platform is designed and realized. The reference implementation connects to a wireless LAN network over Wi-Fi, starts a web server and serves HTML5 web pages and a CSS3 style sheet from SPI flash memory. The sensor data is collected from integrated sensor circuits over an I²C link. Device can run on 3 AA batteries for a combined uptime of at least 3 weeks. Lastly, possible expansion options for the implemented device are discussed and supplemented with real-world examples where possible. Feasible consumer applications for such a platform are then given to conclude.

    ARQ PROTOCOLS SUPPORTING QOS IN EMBEDDED SYSTEMS2008Självständigt arbete på avancerad nivå (magisterexamen)Studentuppsats (Examensarbete)
    Abstract [en]

    Many efforts have been carried out to provide transmission reliability in the history of communication systems. As the demand for real-time applications increased, providing a reliable communication in a timely manner for such applications is strongly desired. Considering timing constraints makes the issue of achieving reliability more difficult. This thesis concentrates on providing reliability for real-time communication in embedded networks by achieving a timing analysis and using the ARQ concept. What is carried out in this thesis is providing retransmission in a real-time manner for embedded networks according to application request. The thesis work focuses on one packet retransmission over a point to point link, but the concept is rich and can be extended to cover application request in real-time embedded networks. Two methods have been fulfilled, and a simulation has been done on the timing analysis focusing on the performance in accepting real-time traffic in the form of separate channels for each application request. The protocol combines ARQ and a scheduling algorithm as a base to support retransmission for hard real-time applications in embedded networks.

    Mobile One Time Passwords and RC4 Encryption for Cloud Computing2011Självständigt arbete på avancerad nivå (magisterexamen), 15 poäng / 22,5 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Cloud services have grown very quickly over the past couple of years, giving consumers and companies the chance to put services, resources and infrastructures in the hands of a provider. Therefore removing the need of providing these services themselves. This can for example lead to cost savings, better resource utilization and removing the need of technical expertise for the customers.

    There is big security concerns when using cloud services. Security is very important in cloud computing since people and companies store confidential data in the cloud. It must also be easy to use the services provided, since cloud services have so many users with different technical background. Since the control of services and data needed for the everyday-run of a corporation is being handled by another company, further issues needs to be concerned. The consumer needs to trust the provider, and know that they handle their data in a correct manner, and that resources can be accessed when needed.

    This thesis focuses on authentication and transmission encryption in cloud services. The current solutions used today to login to cloud services have been investigated and concluded that they don't satisfy the needs for cloud services. They are either insecure, complex or costly. It can also be concluded that the best encryption algorithm to use in a cloud environment is RC4, which is secure and at the same time a fast algorithm. Compared to AES, which together with RC4, are the most common encryption methods used over the Internet today, RC4 is the better choice.

    This thesis have resulted in an authentication and registration method that is both secure and easy to use, therefore fulfilling the needs of cloud service authentication. The method have been implemented in a fully working finished solution, that use a regular mobile phone to generate one time passwords that is used to login to cloud services. All of the data transmissions between the client and the server have been configured to use RC4 encryption.

    The conclusions that can be drawn is that the security proposal implemented in this thesis work functions very well, and provide good security together with an ease of use for clients that don't have so much technical knowledge.

    LTE UPLINK MODELLING AND ANALYSIS OF CARRIER FREQUENCY OFFSET ON UPLINK TRANSMISSION INTERFERENCE2013Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    This master thesis analyzes the effect of Carrier Frequency Offsets (CFO) on LTEuplink transmission, which is the main cause of ICI (Inter Carrier Interference) andMAI (Multiuser Access Interference). A model of the LTE uplink is required toconduct the study and is implemented in MATLAB, in compliance with 3GPPspecifications. The model can generate uplink signal as generated by the UE, (UserEquipment) and it supports multiple channel bandwidths described by the 3GPP.The channel estimation is done with the help of block type pilots. The model is usedto simulate the experimental conditions. The presence of CFO results in poor systemperformance. Therefore, many algorithms have been proposed for the CFOcancellation such as Successive Interference Cancellation (SIC), Parallel InterferenceCancellation (PIC) and Inverse Interference Matrix Cancellation. As the topic is verybroad, I investigate the performance of Inverse Interference Matrix Cancellationalgorithm. Compared with the other CFO cancellation algorithms this algorithm candirectly estimate the interference components from the inverse pilot matrix, thusthere is no need for CFO estimation. Simulation results show that the algorithm isvery effective in the presence of CFO. The channel estimation technique used is theLeast Square (LS) method and frequency selective channel is used for simulation.Performance graphs are plotted in terms of BER (Bit Error Rate) against differentvalues of SNR (Signal to Noise Ratio).

    Abstract [sv]

    Det trådbundna telefonnätet har blivit för dyrt att underhålla och utveckla. Därför håller Telia nu på att ta ner delar av det. För de abonnenter som berörs av detta har Telia en lösning som de kallar fast mobil. Istället för att abonnenterna ringer via det trådbundna nätet ringer de via GSM-nätet istället.Målet med detta examensarbete är att skapa en alternativ lösning till Telias. Vi börjar med att undersöka hur det analoga nätet fungerar. Därefter bygger vi ett eget analogt gränssnitt som kommunicerar med vanliga hemtelefoner. En mikroprocessor kommer att styra en GSM-modul och tolka signaler från det analoga gränssnittet.Resultatet av detta arbete är en apparatur som vi kallar Teletrix – en fast mobil. Med en Teletrix kan vanliga hemtelefoner ringa via GSM-nätet med god samtalskvalitet och med grundläggande funktioner som kopplingston och ringsignal.

    Performance Evaluation of SCTP as a Transport Layer Protocol2011Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    TCP and UDP are the most popular transport protocols used for end-end data transmission. The rapid growth of internet leads to development of many innovative applications in the current environment. Depending on the functionality of these applications, requirements of transport protocols are changing. TCP is known for its problems with Head Of Line blocking (HOL) and SYN attacks which gives reduced performance, and also doesn’t support Multi-Homing. SCTP is another transport layer protocol similar to TCP which provides end-end communication. It has some unique features like support for Multi-homing and multi-streaming. It also protects better from SYN attacks by using four-way hand shake mechanism during association establishment. As an extension to SCTP, CMT-SCTP was proposed to take full advantage of a multi-homed host by doing load sharing over multiple paths. SCTP is believed to be a next generation transport protocol.

    This thesis gives an overview of the SCTP protocol and its features focusing on analysing and testing of failover mechanisms provided by SCTP in multi-homed host, evaluating the transmission performance of SCTP vs TCP in a real network environment. This report also gives a theoretical analysis on how SCTP can mitigate SYN attacks by using four-way handshake mechanism and the state of art of CMT-SCTP.

    High Speed Communication with FPGA2003Självständigt arbete på grundnivå (kandidatexamen)Studentuppsats (Examensarbete)
    Abstract [en]
    This Bachelor of Science degree project called High speed communication with FPGA started January 2003. It is a FPGA related project that was given out by HMS Industrial Networks AB. This project is a part of a research project that is called FASE- FPGA-based Application-Specific Embedded processing, which is a cooperation between HMS, Innovation Team AB and Halmstad University. The ASIC that is in focus in this project, handles the communication on an industrial network. ASIC technology is expensive to develop for small volumes, and gives no room for reconfigurations. This limits HMS, if they want their products to become adaptable for different customers, do they have to change technology. This is where this project starts. This project main purpose is to evaluate if a FPGA based design is competitive compared with an ASIC. This product may be more flexible because it is changeable after development. A FPGA will also be designed to handle a communication to an industrial network and to communicate with a microprocessor. The results of the design were successful.

    EXTREME PROCESSORS FOR EXTREME PROCESSING: STUDY OF MODERATELY PARALLEL PROCESSORS2005Självständigt arbete på avancerad nivå (magisterexamen)Studentuppsats (Examensarbete)
    Abstract [en]

    Future radars require more flexible and faster radar signal processing chain than commercial radars of today. This means that the demands on the processors in a radar signal system, and the desire to be able to compute larger amount of data in lesser time, is constantly increasing. This thesis focuses on commercial micro-processors of today that can be used for Active Electronically Scanned Array Antenna (AESA) based radar, their physical size, power consumption and performance must to be taken into consideration. The evaluation is based on theoretical comparisons among some of the latest processors provided by PACT, PicoChip, Intrinsity, Clearspeed and IBM. The project also includes a benchmark made on PowerPC G5 from IBM, which shows the calculation time for different Fast Fourier Transforms (FFTs). The benchmark on the PowerPC G5 shows that it is up to 5 times faster than its predecessor PowerPC G4 when it comes to calculate FFTs, but it only consumes twice the power. This is due to the fact that PowerPC G5 has a double word length and almost twice the frequency. Even if this seems as a good result, all the PowerPC´s that are needed to reach the performance for an AESA radar chain would consume too much power. The thesis ends up with a discussion about the traditional architectures and the new multi-core architectures. The future belongs with almost certainty to some kind of multicore processor concept, because of its higher performance per watt. But the traditional single core processor is probably the best choice for more moderate-performance systems of today, if you as developer looking for a traditional way of programing processors.

    Abstract [sv]
    A digital fitting-room for frames would facilitate both for customers and staff. Money and time can be saved. To realize the system you have to consider how people interact with the program since it is very important that all target-groups can use it. After interviewing staff and customers, the database was designed. The program was implemented to communicate with the database. A program-shell was created with empty functions that were implemented as the project went on. This was done to simplify the testing. When all functions were ready, there was a system with functions that made it possible to administrate user-accounts and frames. Users could easily try frames digitally by searching among frames and click on the search-results to see them on their faces. The chosen frame could be adjusted by dragging the frame-picture with the mouse to the right position. The result was a prototype of a digital fitting-room.

    The American option pricing problem can be described mathematically bythe well-known Black-Scholes equation with a free boundary. It is difficult to solvethis problem since the free boundary is unknown.To accomplish that, we make use of the Implicit Finite-difference Method and Penalty Method which means to add a continuous penalty term with a small parameter 2 into the Black-Scholes equation,to transform the original free boundary problem into a nonlinear partial differential equation with a fixed boundary.

    Detektering av krypterade filer2011Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    In contemporary encryption the vast amount of text subject to cracking has brought about the demand for methods distinguish files more likely to be encrypted. The encryption software Truecrypt can encrypt files that are not possible to identify with a file signature. To solve the detection problem, an algorithm sensitive to the absence of structure in the very code of files was developed. The program was written in the programming language EnScript which is built into the forensic software suite EnCase. The essential part of the algorithm therefore deployes the statistic of a chi-square test for deviance from a uniform distribution to distinguish files with contents that appear to be random. The program managed to detect encrypted files that were created with Truecrypt. Test results indicate that the newly developed program is nearly double as fast and has at least the same accuracy in the detection as other pro- grams. The software is licensed under open source standard GNU GPL. The procedure developed will drastically facilitate for computer forensic experts to detect if any existing encrypted file is located on the hard drive.

    Forensisk  analys av smartphones: - fokus på sociala medier2013Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    I dagens samhälle är trenden att fler och fler människor införskaffar smartphones för att när som helst kunna vara uppkopplade mot internet. Detta gör att informationen en smartphone hanterar och sparar är viktigare och mer intressant för båda sidorna av lagen. Med denna ökning av smartphones har användandet av applikationer till sociala medier så som facebook ökat.I denna rapport utreds det vad en facebookapplikation lagrar för typ av information efter den har använts och hur pass noga det går att kartlägga vart applikationen har används. För att kunna göra detta krävs först en utredning på vilka sätt de går att hämta ut information ifrån en smartphone. I denna rapport har det alltså utretts huruvida de går att utvinna samma information med hjälp av flera metoder och om de går att uppnå samma resultat med hjälp av en utvinning med de olika metoderna. Vid analys av den utvunna datan visar det sig att applikationen lagrade den intressanta datan i databasfiler. Allt från meddelanden och statusuppdateringar till platsdata sparades i dessa databasfiler, vilket gjorde att enheten gick att kartlägga.

    Abstract [sv]
    We have constructed a model that presents communication by radio and Bluetooth. TetraPak manufacture different machines that rotates and you can´t connect cords during driving, this leads to large restriction of the computer comunication. Our task was to produce a model, that rotates and shows the advantage of bluetooth. TetraPak had some demands of the model. These were that the model should be build in a attractive way, convince the final user about the distribute of using radio waves, some disturbance could be simulated and it will still work normally at last it should show the pretty fast time of response by using bluetooth. Our own ideas and thoughts solved this problems, independent of TetraPak. The model will be used in different exhibtions and demonstrate, by TetraPak, the advantage of wireless communication. We also did an investigation that describes bluetooth, IR and swivel in a fair way, both advantage and disadvantage.

    Noise measurements of a low power detector for RFID applications2012Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    In this work we provide measurements on low power envelope detector and compare them with results predicted by theory. This envelope detector is supposed to be used as a part of low power Wake-up radio for RFID applications. In the work we were mostly interested in noise parameters and blocker effect verification.

    The detector we use is based on CMOS transistors biased in subthreshold region. It gives us low power consumption and high sensitivity. For power consumption about 10 uA and signal to noise ratio equals to 10, the achieved sensitivity is 1.8 mV.

    The results of the work can be used to build low power envelope detector for specific requirements.

    Meshfree methods in option pricing2011Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    A meshfree approximation scheme based on the radial basis function methods is presented for the numerical solution of the options pricing model. This thesis deals with the valuation of the European, Barrier, Asian, American options of a single asset and American options of multi assets. The option prices are modeled by the Black-Scholes equation. The θ-method is used to discretize the equation with respect to time. By the next step, the option price is approximated in space with radial basis functions (RBF) with unknown parameters, in particular, we con- sider multiquadric radial basis functions (MQ-RBF). In case of Ameri- can options a penalty method is used, i.e. removing the free boundary is achieved by adding a small and continuous penalty term to the Black- Scholes equation. Finally, a comparison of analytical and finite difference solutions and numerical results from the literature is included.
