Detta examensarbete är en utvärdering av nätverkssäkerheten hos J BiL AB, både på social och teknisk nivå. Företaget är beroende av säkra Internet-anslutningar för att nå externa tjänster och interna servrar lokaliserade på olika geografiska platser. Företaget har ingen IT-ansvarig som aktivt underhåller och övervakar nätverket, utan konsulterar ett externt dataföretag. Syftet med examensarbetet är att utvärdera säkerheten, upptäcka brister, ge förbättringsförslag och till viss del implementera lösningar. För att undersöka säkerheten har observationer och intervjuer med personalen gjorts och ett flertal attacker mot nätverket har utförts.

I Estland 2007 utbröt vad som kommit att kallas ?Cyberwar I?, vari ett stort antal centrala myndigheters, tillika finansiella institutioners servrar attackerades av massiva så kallade Computer Network Attacks (CNA), utfört av framförallt ryska aktörer. Estland protesterade högljutt, men frågan huruvida CNA är att beteckna som olovligt är allt annat än klar. Prövningen sker mot den folkrättsliga regimen Jus ad Bellum, och huruvida metoden uppfyller vissa centrala begrepp. Men hur skall denna regim appliceras CNA?De frågeställningar som avses besvaras är: hur kan CNA utgöra våld eller hot om våld i enlighet med FN-stadgans artikel 2(4) samt hur kan CNA utgöra väpnat angrepp i enlighet med FN-stadgans artikel 51? Detta avses göras genom en studie inbegripande flertalet folkrättsliga experters teorier på området CNA och våldsanvändning, samt applicering av desamma på en fallstudie av händelserna i Estland 2007.Sammanfattningsvis konstateras att flertalet variabler har bärighet i hur CNA kan uppfylla artiklarnas centrala begrepp, vari frågan om association, effekt, aktör och mål tydligast faller ut.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

Making decisions have always been part of human life. Political decisions consist of many participants with both formal and informal ways to highlight problems and reach the political agenda. Processes difficult for an individual to distinguish and understand surround political decision-making. The purpose of this study is to investigate the decision process for a specific political issue, Swedish wine producers' desire to be able to sell their own wine at their vineyard; gårdsförsäljning. This is currently prohibited in the Swedish model due to an alcohol monopoly.

Syftet med denna studie var att beskriva hur fysiskt aktiva personer som fått diagnosen TIA var. Frågeställningarna rörde vilka aktiviteter studiedeltagarna ägnade sig åt, hur de upplevde sin hälsa, begränsande faktorer, eventuell förändring av aktivitetsvanor, samt om deltagarna fått råd om fysisk aktivitet. Som metod valdes enkätundersökning och 195 enkäter skickades till personer som sökt Universitetssjukhuset Örebro 2007 och fått diagnosen TIA. Resultat: Svarsfrekvensen, efter externt och internt bortfall, blev 74 %. Mer än hälften av de 144 studiedeltagarna var fysiskt aktiva mindre än 30 minuter/dag.

The aim of the study is to investigate what pupils in grade 1 think about reading aloud, reading alone, the selection of books, and the significance of reading. A subsidiary aimwas to examine the relation between the pupils? experiences of reading in the home andtheir ability to discuss a text they have read. A sidetrack in the study aimed to see whether the pupils? experiences of reading in the home affected their outlook on readingin general.

Investment costs for eight different type housing systems for dairy cows has been calculated in order to compare the building costs as a function of herd size, shelter type and automatization. A commercial calculation programme for building was used and complemented with prices of equipments specific for dairy cow building. Herd sizes were 120, 250 and 400 cows. The milking equipments were automatic milking system (AMS), parallel parlour with 32 stalls (2x16) and rotary parlour with 24 stalls. Shelter was either insulated equipped with automatic cable driven scrapers on solid alleys, automatic feed wagon on rails, or uninsulated with manual manure handling and a tractor driven mobile mixer wagon on a drive-through feeding table. Building cost per cow or per kg milk was calculated using an average life time and 6 % interest rate and annual milk yield is 9 500 kg/cow and year. Structure effect 3-4 % higher for an insulated structure than in an uninsulated for 400 and 120 herd respectively. This is much lower compared to what is normally argued.
