Hästhållningen i Sverige 2009 : intervjuer med 52 hästhållare i 5 kommuner

The purpose of this degree project is to investigate how horse keepers reasons about horse keeping and how the horse keeping looks like today. It is interesting to compare modern horse keeping with ancien recommendations and how the horses were kept then to understand how much in the horse keeping today that is based on traditions instead of research and science. The degree project was based on data from interviews of 52 horse keepers in five different municipalities. All interviews have been based from the same questionaire about how there horses are kept today, what they think about different housing systems, how they think horses will be housed in the future and what problems they think are the biggest in horse keeping today. The results shows that single boxes indoors are the most frequently used housing system today.

Analys av användning av Intelligent Power Modules för motorstyrning

Det här arbetet utfördes på ABB Corporate Research, och innefattar en studie av motorstyrning i allmänhet, och hur man med hjälp av en Intelligent Power Module kan effektivisera motorstyrning genom att ersätta separata kraft- och styrmoduler med en kombinerad modul. En IPM från International Rectifier har modifierats och testats genom att under en längre tid låta den styra en permanentmagnetmotor under normala förhållanden. Resultatet från testkörningen visar att en IPM är ett bra alternativ i framtiden, såväl i fråga om effektivitet, som kostnad och utrymme. Efter en undersökning av marknaden visar det sig att det är långt ifrån säkert att modulen från International Rectifier är den bästa som finns att tillgå, och det skulle förmodligen löna sig att testköra IPM:er av andra tillverkare i mån av tid och pengar..

Drömjournalen : En studie av vårdmedarbetares upplevelser av samtida och framtida vårdkommunikation

The effectiveness of communication in the Swedish healthcare system context has long been the subject of debate. Issues stemming from usability, accessability and interpretation affect the lives of patients, and yet the vocal groups in the healthcare communication debate are patients and administrators, not healthcare professionals. With the advent of eHealth services and new demands being put forth on the ability of healthcare professionals' to handle increasingly numerous and innovative systems, it is of more importance than ever to understand the healthcare professionals' work context. This article is based on interviews with five healthcare professionals concerning their views on electronic health records (EHR), eHealth services, trends in healthcare services development in Sweden, as well as their views on the future of eHealth solutions and health information technology (HIT). Analysis of collected information shows an apprehension among healthcare professionals towards electronic communication, as well as a dissatisfaction with the usability of modern healthcare systems.

En utredning av Rom I-förordningens artikel 4.1(h)

Article 4.1(h) in the Rome I regulation establishes which law that will be applicable on contracts concerning financial instruments concluded in multilateral systems. The main problem is that most contracts concluded within these systems have standard clauses which contain a clause on the applicable law. If this is the case, Article 3.1 in the Rome I Regulation is applicable instead. This problem makes it difficult to find a need for article 4.1(h) if it will only be applicable in exceptional cases. However, the legal position on this matter is still unclear since the Rome I Regulation has just been put into force.

Air power och asymmetri ur ett högteknologiskt perspektiv : en fallstudie av Operation Desert Storm, Deliberate/Allied Force och Enduring Freedom

Uppsatsen syftar till att bidra mot ökad förståelse för användandet av Air Power i olika miljöer.Uppsatsen strävar efter att belysa på vilket sätt man har nyttjat högteknologisk Air Power för atterhålla optimalt operativt övertag samt att undersöka vilka risker det eventuellt har inneburit.Detta uppnås genom att studera tre konflikter under 1990-talet och se hur man har använt sig avAir Power och titta på vilken effekt detta har haft. Det primära syftet är alltså att undersöka omhögteknologi är fördelaktigt att använda i olika nivåer av konflikter, eller om avsevärda nackdelarvisar sig.Uppsatsen syfte har också varit att identifiera hur de insatser som genomförts med dominerandeAir Power har påverkat och påverkas av teknologiska utvecklingsskillnader mellan länder.Då all krigskonst handlar om hur man nyttjar sina förutsättningar på bästa sätt blir det logiskasteget att en mindre teknologiskt utvecklad fiende kan göra högteknologisk krigföring ineffektiv.Följande hypotes prövas under arbetet: Högteknologisk Air Power är effektivt även vidasymmetrisk krigföring och vid lågintensiva konflikter.Resultatet ur studien visar att det finns både positiva och negativa effekter. De mest framträdandefördelarna är att teknologin medger flexibelt nyttjande och korta omloppstider, underlättarsamarbete och innebär vidare att ett högt tempo kan hållas genom operationen.Och nackdelarna är att det visar sig vara relativt enkelt att försvara sig under lång tid med småenkla resurser, detta kan visa sig svårhanterat för den politiska nivån. Resultatvärderingen avinsatta medel sker änsålänge alldeles för långsamt.En högteknologisk angripare gör fienden rörligare vilket i längden innebär svårigheter för denegna beslutshanteringen..

Analys och organisering av ö-drift för en samförbränningsstation vid Åmotsfors bruk

Åmotfors Bruk AB (ÅBAB) has today an inefficient production of steam for the manufacturing of paper. Unpredictable energy prices and modernisation of the current equipment has been the underlying factors to invest in a thermal power plant, mainly driven by garbage. This facility will not only use the steam for paper production, it will also generate electricity through a steam turbine. Today, when a fault on the supplying line occurs which leads to disconnection of the external grid, all the support of electricity to Åmotfors Bruk (ÅB) will disappear. This will lead to major interruptions in the paper production, which will cause severe economical losses.
