Den här rapporten beskriver arbetet och utförda studier inom området kryptering och VPN. Fokus ligger på hur väl krypteringsalgoritmerna Triple Data Encryption Standard (3DES) och Advanced Encryption Standard (AES) skalar i en förutbestämd miljö. Huvudfokus har varit att svara på frågan: Vilken av krypteringsalgoritmerna AES och 3DES kräver minst systemresurser? Under utbildningstiden har det flera gånger framförts att 3DES-algoritmen skulle vara mer krävande för krypteringsenheterna att utföra jämfört med AES. Denna rapport söker finna om det är så det förhåller sig och i så fall hur stor skillnaden är mellan algoritmerna.

Många utav de krav som idag utformas uppfyller inte kriterierna för att vara högkvalitativa. Denna undersökning behandlar hur användbarhetskrav formuleras i kravspecifikationer. Vi har i vår undersökning utgått ifrån en internationell standard (ISO/IEC/IEEE-29148), som innehåller kriterier för hur både individuella och uppsättningar av krav ska formuleras, som teoretisk modell. Dessa kriterier har vi forskningsförankrat genom att studera vad andra forskare sagt om dessa och därefter har vi använt modellen för att genomföra en dokumentanalys av fem olika kravspecifikationer för fem olika informationssystem. Våra slutsatser påvisar att det kan finnas en brist på kunskap kring hur krav bör formuleras i en kravspecifikation och vi belyser även de samband som finns mellan olika grader av uppfyllelse för kriterier hämtade från ISO/IEC/IEEE-standarden och praktiken.

Examensarbetet har utförts på Trätrappor Norsjö AB under månaderna april ? juni 2013. Trätrappor Norsjö AB har under senaste två åren arbetat målmedvetet med att effektivisera tillverkningsprocessen för att uppnå en effektivare tillverkningsprocess och minskade kostnader. Vi valde att examensarbetet skulle omfatta kvalitén då den är en stor och viktig del i arbetet mot en förbättrad totalproduktivitet. Vid arbetet med OEE har kvalitén en stor inverkar på de två andra delarna, nyttjandegrad och tillgänglighet.För att undersöka vilka kvalitetsavvikelser som upptäcks i samband med paketering upprättades ett protokoll som har fylls i av operatörerna vid paketeringsstationerna, när avvikelser upptäckts.

Modelling of pollutants is commonly used in research and at departments working with environmental issues. The need to use large amounts of data when modelling creates the opportunity for more generalised models with lower data demands. Aggregating functions into coarser elements is a sort of generalisation of actual features in nature.A development of a method and a modelling tool called ?KadmiumKalkylatorn? has been performed to model cadmium pollution in rivers in Skåne, Sweden. The water runoff has been multiplied with cadmium standard concentrations based on membership in landuse classes.

The goal of this project was to make the requirement process at the Swedish Coastguard more effective. The first step to achieve this was done by locating bottle necks in the process with value stream mapping method. The result of this study showed that the biggest restriction in the requirement process was while examining older requirement documents to understand what elements were suitable for the particular project. This was followed by a study of literature, interviews and theory of Lean Production with the ambition to investigate how the requirement process was handled on other companies and how to improve the process on the Swedish coast guard. This led to a number of potential enhancements of the process which later was evaluated.

This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods.

The purpose of this report is to simplify the process of designing carbon fiber strengthening for existing concrete constructions, specifically beams. The intention has been to establish a flow chart containing information on the necessary testing and calculations for the design, to as far degree it is possible satisfy the requirements stipulated by Swedish and by extension, European authorities.To do this the report will examine a parking garage situated underground by Akademiska Sjukhuset, Uppsala. The parking garage was built in the mid-seventies, and has in recent years been subjected to a greater load than designed for by the construction of a road on top of it. FEM-Design has been used to obtain the internalforces of the beams and thereby determine whether they are in need of strengthening or not and thereafter design the strengthening according to Täljsten (2006) with some corrections from Täljsten (2011) due to new regulations.The result of this report is that the flow chart used is viable to design carbon fiber strengthening, atleast with the conditions met in our reference project.The conclusion drawn after working with this report is that there is a need for a clear standard for carbon fiber strengthening , preferably a standard that can be used throughout Europe..

In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely. The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished the result is graded in the following categories: economy, environment and quality. To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.

Scania CV is one of the world's largest truck manufacturer. It is not only the directproduction of vehicles and methods that are important for Scania but also the servicemarket handling spare parts, repairs and workshops. The department Vehicle ServiceInformation construct standard times through work measurement for particularworks in the workshops. The software application STAM is used in the servicemarket to create and store standard times which then are exported to theworkshops' own systems.The purpose of this master thesis is to analyse and evaluate the internal workmeasurement system that includes standard times and the software STAM. Also,based on external analysis and benchmarking of other systems suggest appropriatefuture development within the area for Scania Vehicle Service Information.In order to perform the investigation, interviews and studies have been doneinternally at the departments that are involved in work measurement as well asexternally at Scania workshops.

Föreliggande studie är en komparativ fallstudie där Antoine de Saint-Exupérys LePetit Prince och dess svenska översättning analyseras enligt Juliane Houses analysmodellför översättningskritik. Som jämförelsematerial till den svenska måltextenhar de två engelska översättningarna av verket använts. Syftet med undersökningenär att analysera effekterna av eventuella skillnader mellan den aktuella källtextenoch dess svenska måltext samt att genomföra och redovisa en fallstudie som eventuelltskulle kunna ingå i en mer omfattande studie av exempelvis barnboksöversättningarfrån franska till svenska. Originaltexten är avsedd för både barn ochvuxna och kan, om läsaren vill, på olika sätt tolkas symboliskt eller allegoriskt.Texten visar sig också ha en synnerligen välplanerad och koherent komposition,vilken till största delen har bevarats i den svenska måltexten, men några avvikelsersom påverkar kompositionen har dock påträffats. Även avvikelser som kan påverkamålspråksläsarnas förutsättningar att tolka en del av de symbolladdade orden harnoterats, liksom avvikelser som påverkar uppfattningen av relationen mellanförfattaren och läsarna samt mellan de fiktiva personerna i texten.

Abstract The IT- business is a fast growing business trade. This expansive line of business continuously demands flexibility both economically and legally. It is, today, of great importance to have knowledge about your own trade especially when it comes to new agreements. Laws and regulations are seldom flexible and adaptable tools, this is due to the fact it takes time to create new laws and, above all, it takes time to create laws with the right effect. This is where standard agreements enter the scene.

This report describes an bachelor thesis work which is performed in cooperation with SVIA that develops and sells automation solutions for the manufacturing industry. The thesis purpose was to evaluate the machine FeedLine to find opportunities for improvement in the product?s design that could lead to more standardization and thus improving the efficiency of manufacturing and assembly.Based on these basic issues suggestions for improvements were developed:How can the design of FeedLine be improved to facilitate the assembly?Can more standardization be imposed on FeedLine?s design to enable more stocking of standard components?An initial pre-study was conducted to evaluate FeedLine?s to find opportunities for improvement in its overall design. During the pre-study staff at SVIA and two of its clients was interviewed. Based on information gathered during the interviews and observations by the authors improvements was amendments.

As break downs of production transformers are costly and often result in long outages it is essential for reliability of operation that the transformers are manufactured to be robust. The aim of this M.Sc. thesis is to investigate if deviations should be made from the standard IEC 60076 ? Power Transformers in order to describe a robust large power transformer for procurement.The investigation has been conducted in three stages. In the first stage a definition of the term robust was developed in consultation with the client Vattenfall Vattenkraft.
