The research objective of this thesis was to conduct a holistic evaluation of an operational information system. By holistic evaluation we mean that an equal focus was placed on both the system system perspective and its users user perspective, in the actual environment where the system and its users function contextuality. In addition, the methodological objective of the study was to test a new research approach in a real life setting. The participants of the study were twenty newspaper journalists employed at Göteborgs-Posten GP. The information system NewsLink is a manually indexed full-text database containing all articles published in GP since 1994.

A key part in the development and verification of digital systems is simulation. But hardware simulators are expensive, and software simulation is not fast enough for designs with a large number of gates. As today?s digital zesigns constantly grow in size (number of gates), and that trend shows no signs to end, faster simulators handling millions of gates are needed. We investigate how to create a software gate-level simulator able to simulate a high number of gates fast.

Tractors of today come equipped with a CAN-system. A CAN-system sends information from sensors to electronic control units who process the signals. The sensors measure several interesting parameters such as force, pressure and speed for various components of the tractor. This thesis discuss a force sensor which is placed in the pivot of the tractors three point linkage, the sensor measure the horizontal reaction force from the load that the tractor is exposed to. Signals from this sensor can be used to measure the force from any implement that the tractor is exposed to during an operation.

ESAB is a world leader in production of welding consumables and equipment. The company manufactures, among other things, welding electrodes. A roller straightening unit is used in the cutting process to straighten the wire, which the welding electrode consists of, by adjusting some of the rollers during operation. According to ESAB?s standard and the European machinery directives, moving parts of machinery, such as rollers of the roller straightening unit, must be out of the operator?s reach.

Under en operation behöver patienter tillföras vätska. Det finns en pågående diskussion om vilken sorts vätsketillförsel som har fördelar för patienterna. Framförallt diskussionen om glukos ska tillföras eller inte. Förhöjda blodsockervärden under och efter operation har visat sig ha negativa konsekvenser för morbiditet, mortalitet och vårdtid. Det finns inga entydiga riktlinjer kring peroperativ vätsketillförsel.SyfteAtt se hur plasmaglukosvärdet hos patienter som tillfördes eller inte tillfördes glukosinfusion vid planerad kolorektal kirurgi förändrades över tid, per- och postoperativt, och hur detta påverkade diures och illamående de första fyra timmarna postoperativt.

En viktig del av en nations säkerhetspolitiska ambition handlar om att skaffa sig handlingsutrymme. Detta görs genomen orkestrering av nationens olika maktmedel. På militärstrategisk nivå skapar en samordning av politisk målsättning,doktriner och resurser en samlad nettoeffekt, vilken utgör nationens möjliga militära strategi.Efter att det kalla kriget upphört har stora förändringar i den säkerhetspolitiska miljön för bland annat Sverige ägtrum. Sverige har därför förändrat sin säkerhetspolitiska utformning och Försvarsmakten och dess luftstridskrafter harföljt efter. Det svenska flygsystemet skall idag exempelvis kunna användas i av NATO eller EU ledda fredsframtvingandeoperationer.

Syfte ? Syftet med denna uppsats är att få ökad förståelse över varför kunder väljer att använda självbetjäningstjänster (SBTs) och vilken påverkan detta har på kundens roll i användandet.Design/metod/tillvägagångssätt ? Studien har en kvalitativ ansats och genomfördes med semistrukturerade intervjuer. Totalt har 31 kunder intervjuats på IKEA i Kungens Kurva, Stockholm angående deras användning och upplevelse av SBTs.Slutsats ? Studien visar flera olika faktorer som påverkar kundernas användning av SBTs till exempel dess tillgänglighet och enkelhet. Kunderna upplever deras förändrade kundroll som tyngre än tidigare och deras inställning till företaget förändras på grund av SBTs.Studiens begränsningar ? Studien har för få antal respondenter för att generalisera resultaten och vi har enbart studerat en bransch och ett företag.

Logistic Culmination ? One or Two Sides of the Coin?An Observation From a Different Point of View Logistic culmination can be compared to a stretched rubber band. If combat units moves in direction away from the supplies the rubber band will gradually stretch. The rubber band will eventually burst and at that point the logistic culmination will be a fact. But if the rubber band was to be let go before bursting, it will instead be contracted.

Bakgrund: I Sverige opereras 24% av de extremt för tidigt födda barn (EPT) för öppetstående ductus arteriosus (PDA). EPT barn som behandlas med ductuskirurgi riskerar få i sig för lite energi och makronutrienter på grund av volymrestriktioner och rädsla för att påbörja enteral nutrition efter genomförd operation och därigenom utveckla nekrotiserande enterokolit (NEC). NEC är ett ischemiskt och inflammatoriskt tillstånd hos prematura barn i vilket delar av tarmen nekrotiseras (vävnadsdöd).Syfte: Att beskriva tillförsel av energi, makronutrienter och vätska inför, under och strax efter ductuskirurgi hos EPT barn.Metod: En svensk populationsbaserad kohortstudie av EPT barn födda mellan åren 2004-2007 och som opererats för PDA (n=140, 83 pojkar, genomsnittlig födelsevikt 723 g). Utförlig information avseende perioperativ nutrition inhämtades retrospektivt från sjukhusjournaler. Det dagliga intaget av enteral- och parenteral nutrition samt blodprodukter användes för beräkning av intaget av energi, makronutrienter och vätskevolymer tre dagar före fram till och med tre dagar efter operation.

This thesis was commissioned by Tekniska verken, Energy Division with the overall aim to investigate the concept of environmental debt and what it means for a business. Furthermore, a sustainable risk and responsibility investigation shall be carried out on the concerned areas. Finally, the priority areas shall be highlighted and proposed actions presented. The Swedish Environmental debt concept was presented in 1992 by Arne Jarnelöv. Environmental debt is defined as restoration costs for environmental damage. In the early days the concept did not take into account who was responsible, but the environmental debts was regarded as a humanity debt to future generations.

Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.

During 2009-2010 Sweden participated in an international military operation whose intention, according to the Swedish news media, was to fight Somali pirates. The purpose of this thesis is to study various decisions and documents behind the Swedish efforts, both military and foreign aid, regarding the matter of Somali pirates during the years 2009-2010 and analyze the results using an interpretation of the security-development-nexus-theory. The method used is text analysis based on the hermeneutic idea of understanding and interpretation.The thesis studies the international resolutions and national decisions that lead to the military operations in the Gulf of Aden and also the international strategies and national approaches regarding Sweden's assistance in the development of Somalia. The theoretical section contains an interpretation of the vast security-development-nexus-theory. The concepts of security and development are first presented separately and then collectively in terms of military security, societal security, economic security, regime security and human security.

The purpose of this paper was to analyse ?Identity- about trademarks, signs and symbols?. The project was a co-operation between the National museum of Art and Stockholm School of Economics in the spring of 2002, which consisted of an exhibition, a book and a series of seminars. The goal was to illustrate how the trademark had developed through history, which role it has in the modern society and how the trademark serves as a creator of identities. The project, mostly the exhibition, was exposed to criticism, which was directed towards the sponsorship deals between The National Museum of Art and five companies..
