Säkerhetsutvärdering certifikatserver i stället för aktiva kort
Business and organizations use computer network in a greater extension than ever before, especially for business-critical use. That increase the demand of security for all systems, both against internal and external threats. The demand on the authentication method used today increases. Today they normally uses password or some kind of smart card. I will performa literature study that will investigate the possibility to increase the security in authentication of users without the use of extra hardware.
Design and Implementation of an Application. Programming Interface for Volume Rendering
To efficiently examine volumetric data sets from CT or MRI scans good volume rendering applications are needed. This thesis describes the design and implementation of an application programming interface (API) to be used when developing volume-rendering applications. A complete application programming interface has been designed. The interface is designed so that it makes writing application programs containing volume rendering fast and easy. The interface also makes created application programs hardware independent.
NOVA : Funderingar kring ett shoppingcenter med utgångspunkt i fenomenologin
This thesis deals with a Swedish shopping centre, NOVA, from a phenomenological point of view. Starting in my own experience of the architecture I discuss issues such as gender, consumerism and the image of the ideal society, the Heterotopia, as they appear to me in my studies of the building.Divided into three different themes I then discuss the aspects I?ve found through my meeting with the architecture in comparison to a number of texts on the subject.My phenomenological analysis, combined with earlier research, presents to me a number of aspects more evident than others, as I do my own interpretation of the building and its architecture..
Modellering och simulering av hydraulik för användning i hardware-in-the-loop
Modeling and simulation is growing ever more important in the development of new products. This thesis describes the use of Hopsan for hydraulic modeling and its use in conjunction with Simulink with the intent of using the model in a hardware-in-the-loop setup. A sensor layer has been created in Simulink to emulate all the internal sensors in a modern forklift. The details of using legacy C-code instead of a hardware MCU for a fully simulated environment, software-in-the-loop has been outlined. There are two major routes one can follow implementing software-in-the-loop, exporting the C-functions to CAPL via a export layer or creating an s-function in Simulink.
Utvärdering av produkter för säker autentisering i Windowsmiljö
In this report hardware based alternatives to password authentication in a Windows domain are evaluated for the needs of a certain company. In order to investigate the demands on such alternatives interviews with people concerned have been carried out. The demands which resulted from the interviews have been used to select types of hardware tokens for evaluation. Two products which offer authentication with smart cards and USB tokens have been selected and closer evaluated. These are RSA Passage which offers both hardware options and Rainbow iKey which uses USB tokens.
Värdet av Enterprise Arkitektur i en verksamhet. En kvalitativ studie av hur man förklarar värdet av att använda Enterprise Arkitektur i en verksamhet i olika mognadssteg
The purpose with this report is to highlight the value which Enterprise Architecture (EA) can bring,including the effects that can emerge, for a business. In the report we also study how Enterprise Architecturemay serve as basis for generating even more business value. The study is based on a theoretical frameworkwhich covers the following perspectives; architecture design, strategy development, management of changeand evaluation of IT-investments. Gathering and analysis of empirical data has been performed using acustom-developed model which is based on a model from Sogeti called Dynamic Architecture (van DenBerg and van Steenbergen, 2006) and Innovation Value Institute?s maturity curve (Innovation ValueInstitute, 2008) for Enterprise Architecture management.Explaining the value of Enterprise Architecture is invariably an important topic since many organizationsexpect to be able to generate quick value of the investments made in Enterprise Architecture.
Godshantering med Scania Interactor
This thesis is about making a support for barcode readers and RFID readers on a computermounted in heavy vehicles. The computer has several applications designed for heavyvehicles such as an order handling application. The goal was to suggest an architecture toimplement a support for the readers. The architecture should be independent of whichmanufacturer who has made the reader hardware that was connected to the computer.At first a theoretically study was made around RFID technology and standards for thetransport and supply sector. Then the architecture was developed and a demo implementationwas made.The conclusion of this thesis is to implement support for barcode readers with a wedgeapplication.
Jämförelse av klientlösningar
In this report I have made various comparisons between different client solutions; a standard client solution (PC-server), to use as a comparison and look at various differences in costs against the other client solutions that I have compared, which is Windows Thin PC, Dell Wyse, Red Hat Enterprise Virtualization and FSData terminal server/thin clients. All these solutions require a form of server to work against, which also the standard solution uses, but the main difference is that most of the data and computing power is on the server instead of the client.Window Thin PC, Dell Wyse, Red Hat EV and FSData all use some kind of thin client as hardware. Some of the main differences is that Windows Thin PC can be installed on almost any hardware. Dell Wyse is a special hardware group from Dell, that uses its own proprietary software, and Red Hat EV which is based on linux, is the cheapest option where the only cost is for support. FSData terminal server/thin client use as the name suggest a terminal server and a form of thin client to connect to it, the solution essentially means that your rent the complete hardware from FSData.The comparisons are made with the view of different scenarios based of the number of clients, where costs and licenses, as well as time spent on installation, upgrades, monitoring and managing are some of the main points raised..
Resurseffektivt bussprotokoll o?ver RS-485
This report describes the design and implementation of a multi-master, packet based protocol for small and tiny microcontrollers where resources are limited. The protocol was named "Tiny Controller Network" or TCN for short. The protocol is meant mainly as a control bus for automation and sensor acquisition applications but due to its flexibility can also be used for other purposes as well. It borrows some of its functionality and design ideas from the well known CAN bus and Modbus but also has a number of major differences like the use of standard hardware and time synchronisation. One of the key aspects during the design was the use of very little system resources and common on-chip hardware peripherals like a UART.
Kommunikationsgränssnitt för hårdvaruinventering av IS-baserade system : Communication interface for hardware inventory of Integrated Site
The purpose of this thesis was to create a communication interface which insures that all the right hardware is in its right place in the IS-node before Ericsson AB delivers it to their customers. One of the first parts of this work was to make sure it is possible to create such an interface for IS. This thesis then explains how to construct an interface that retrieves information from the IS-node into a C#-application. One important part of this project was to collect information and transform it to an XML output with the purpose of then being used in other applications in the future. The application created within the scope of the thesis exports the information retrieved from the IS-node in an XML-file or a text-file.

Kunskapsorganisation av ämnesområdet arktektur : Klassifikation eller indexering av samlingarna på en arkitekthögskola?
This thesis analyses the problem of how to organise a multidisciplinary domain of knowledge like architecture. The study is both theoretical and empirical. The theoretical part include discussions of theories of knowledge organisation. Two different principles of classification were examined in relation to the domain itself, as well as in relation to the educational programme at the School of Architecture at Lund University and comparable schools in Sweden. The empirical part is a case study carried out at the School of Architecture at Lund University.
Att välja perspektiv : "Arkitektur i Sverige - Funktion, konstruktion och estetik genom tiderna".
This essay tries to show how The Swedish Museum of Architecture, Stockholm, with the exibition Architecture in Sweden - Function, Design and Aesthetic through the Ages, presents and represents architecture. It is stated that this is done in a multi-perspectival, multimedial fashion, with the aid of, for example, photography, models and mixed material surrounding the wide concept of ?architecture?. One chapter discusses the relationships between the exhibition on site, the exhibition catalog and the museum´s website. Another chapter argues that there can be no essential or perfect representation of architecture, although this utopian wish most certainly exists even today.
Hardware-in-the-Loop simulering av motorservon på ett inbyggt system
This report presents a master thesis project performed at Elekta AB during the fall of 2013 and early 2014. Elekta is a medical technology company and their main product in the Stockholm office is a gamma knife used for radiosurgery. The gamma knife contains a cluster of a dozen motor servos and motors used for adjusting the patient and the radiation sources over a CAN bus. A self-developed hardware-in-loop simulator running on a PC with LabVIEW is currently being used for integration level testing of the control system of the gamma knife. The simulator has some problems with it not running in real-time and having other performance issues.
Syntetiska Instrument
This thesis aims to investigate SAAB AB´s possibilities to use synthetic instruments in their test systems. The reason for this is reducing costs and the risk of obsolescence which is common when test systems operate for several decades.The market around synthetic instruments has been explored in the search for suitable hardware and software. Software has been developed in LabVIEW and synthetic instruments have been created with the help of IVI-drivers. The hardware consisted of PXI-instruments (Waveform generator and Digitizer), connected to a computer using a fiber optic link and PXI-chassi. The created instruments was then compared to common instruments used today, and the comparison turned out well.
