Trycksättning och dimensionering av brandhiss för berganläggning
This thesis deals with the design of a combinated rescue-, personal-, and firefighting elevator for a nuclear waste storage facility to be constructed by the client SKB, Svensk Kärnbränslehantering AB. SKB:s mission is to dispose of all nuclear waste from all swedish nuclear power plants. The storage facility will be built in the rock 450 m under the surface and will consist of several kilometers of tunnel where capsules containing the nuclear waste will be placed. It will also hold a central area which contains spaces necessary for the operation and construction of the facility, such as elevator hall, storage hall etc. The facility will have two ways of access: a vehicle ramp and an elevator shaft.
[Men det är ju så det borde vara...] : en kvalitativ studie om sex unga kvinnors förhållande till kvinnlighet
The aim of this study was to try to identify what young women see as typically female and how this affects them as individuals, focusing on the female body. How free or limited do they consider themselves to respond to prevailing ideals of beauty, to men and other women. Our questions are how young women construct femininity through the body and why? We do this by using a holistic gender perspective and with the help of key theoretical concepts; gender, normative femininity, heteronormativity, performance, freedom/power and the female body,. We have had a qualitative approach and we have done interviews with six girls in secondary school age.
Dimensionering av vägens bärlager : Hur påverkar asfaltbetongblandningen och hur effektiv är svensk dimensioneringsmetod?
Det här arbetet handlar om asfaltbetongblandningar och hur variationen av dessa vid projektering påverkar vägarnas dimensionering i överbyggnaden mer specifikt bärlagret. Arbetet är baserat på litteraturstudier av den senaste teorin kring dimensionering av asfaltbetongblandningar i väglager samt tillhörande kravskrifter både från svenska och amerikanska myndigheter. Den inledande delen i examensarbetet omfattar bakgrunden till vägdimensionering. Inledningsvis behandlas materialet asfaltbetong och derss egenskaper för att sedan gå vidare till allmänt om vägar, hur de utformas, vägens funktionella egenskaper och skador som kan uppstå. Detta ska ge läsaren tillräckligt med bakgrund för att följa med i resten av arbetet där man kan läsa mer ingående om deformationsskador och vilka parametrar som är till stor vikt när man studerar skador som uppstår i asfaltbetongen samt relationen till dem egenskaper bitumen har. Rapporten avslutas med att resonera kring eventuella problem kring dimensioneringsmetoder samt betydelsen av blandningens hållfasthetsegenskaper och hur de påverkar vägarnas tjocklek. Slutsatsen i rapporten är att asfaltbetongblandningen har en betydelse för dimensionering av bärlager och att det kan vara någonting att beakta oftare vid vägdimensionering speciellt vid blandningar som skiljer sig mycket från standardvarianterna..

Pig behaviour during crowding : a study in organic and conventional herds
Rearing in organic pig production differs from conventional rearing; pigs have outdoor access and larger space allowances. Regardless of production system all pigs are transported before slaughter and during transport pigs are crowded together in a new environment and in a space smaller than they are used to. As pigs in organic herds are reared at even larger space allowances than conventional pigs, such crowding could possibly have a stronger impact on pig behaviour and well-being. Six pig producing herds, three conventional and three organic, were visited and pigs from each herd were enclosed during 12 minutes in a test area corresponding to the crowding on a transport vehicle. During the crowding, pigs? behaviour was observed, before and after enclosure in the test area skin lesion scores were recorded, and also measures of heart girth (for weight estimation) was done.

TOMO Hugglink
Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.
Markstation : koncept för en användarvänlig markstation i ett UAV-system
Syftet med det här projektet var att utforma en användarvänlig markstation till ett UAV-system.UAV står för Unmanned Aerial Vehicle och är benämningen på den obemannade luftfarkosten i ett UAV-system. Det aktuella UAV-systemet i det här projektet består av en UAV, eller drönare som den även kallas, och en markstation. Markstationen innehåller en R/C (Radio Control, styrenhet för manuell radiostyrning), en laptop och en antenn för videonerladdning. Drönaren styrs från marken av enoperatör via R/C:n men kan även flyga autonomt vilket innebär att operatören iförväg programmerat in en rutt med GPS-punkter som drönaren självständigt kanflyga efter. Drönaren kan utrustas med olika former av sensorer som laddar ner sina bilder kontinuerligt under flighten till operatörens laptop i markstationen.Uppdragsgivarna till projektet var de norska UAV-systemleverantörerna Scandicraft AS.
Usability för svenska folkbibliotek : En undersökning av svenska folkbiblioteks datorsystem med hänsyn till användarvänlighet.
The aim of this essay is to examine three separate Swedish public libraries and their respective websites on the grounds of the usability sciences. I firstly had to summarize the main properties of the usability-field in order to gain an extended knowledge of its purposes and possible usage for today?s library systems. I was then able to apply the extended knowledge in the examination of the three library websites and the purpose of determining whether or not they were designed according to the standards set by the usability-sciences.Usability is a rather new science that deals with the dissection and examination of computer-based systems, in order to find the key components that make systems user-friendlier. With user needs being the main focus of its research, usability tries to meet all the different needs of the modern user and construct systems that are less system-centered and more user-centered.
Utveckling av yteffektivt elfordon för hyrsystem
Dagens bilar är gjorda för långa resor med högt ställda krav på bekvämlighet och komfort. Studier har visat att de flesta resor som görs i Storstockholm är korta, och därför är kravet på prestanda och komfort minimalt.Syftet med detta projekt var att ta fram ett enkelt pendlingsfordon som del av ett hyrsystem. Användaren hyr fordonet vid en station och lämnar av den vid en annan.Fokus har legat på att utveckla en parkeringslösning som spar plats. Att bygga parkeringsstationer i förbindelse med befintlig kollektivtrafik är svårt, och marken i Stockholm är både begränsad och dyr.Efter en omfattande förstudie fastställdes en kravspecifikation som låg till grund för den fortsatta konceptutvecklingen.Det slutgiltiga konceptet blev Electric Commute Vehicle, ett elfordon avsett för personlig transport och pendlingstrafik. Fordonet döptes till X-traffic (Cross-traffic) och har utrustats med en unik parkeringslösning där fordonen packas likt kundvagnar.
Att minska alkohol och droger i trafiken : Erfarenheter av modellen SMADIT Västmanland
Varje år omkommer cirka 500 personer i trafiken och runt 20 000 personer skadas. Betydande riskfaktorer till trafikolyckor är alkohol och droger som blivit allt vanligare förekommande. Det uppskattas att mellan 12 500 ? 15 000 personer kör onyktra på landets vägar dagligen. Rattfylleristerna domineras av yngre och medelålders män och ungefär två tredjedelar av rattfylleristerna har ett alkoholproblem.

???????????? ???? ??som?leder oss i triumf?? En exegetisk studie gällande vad Paulus avser för betydelse och funktion med sin metafor i 2 Korintierbrevet 2:14a.
AbstractIn this essay I examine the exegetical problems concerning the interpretation of the metaphor ???????????????? in 2 Corinthians 2:14.The regular idea of the metaphor is that the apostle Paul is using the picture of a Roman triumph to describe the apostle?s and his co-worker?s service for God. This includes that God is leading them into many sufferings finished off with a martyr death as the triumph was very painful for its prisoners and mostly ended with an execution. But since A.D 300 such an interpretation has been questioned. Scholars react primarily to the cruelty of it and ask if that really was Paul?s meaning.
Arbetet med iPad i förskolan : En undersökning om hur man arbetar med iPads i en mellanstor kommun
Researchers, planners, and government agencies agree that road safety for children must be a priority and in particular that children should have a safe and secure way to travel to and from school regardless of age or the distance travelled. In Sweden, child traffic safety is a key part of the country?s Nollvision, a long-term traffic policy goal of ?no deaths or serious injuries?. Unfortunately, many countries have recorded increases in child traffic accidents as the percentage of parents who drive their children to school and thus congestion around schools has increased. Common strategies include traffic safety education for children, the redesign and improvement of traffic infrastructure, bicycle training, and carpooling.This thesis assesses the traffic problem around Ludvigsberg School in the district Valbo in Gävle, Sweden.
Virkesgripen, ett geometriskt verktyg :
The aim of this study was to investigate and describe conceptions that been used when people talks about grapples and to put together parameters that the customers sees as important when they chose a grapple from Hultdins.
Every year Hultdins manufacturer and sells about 3500 grapples around the world. With so many users its difficult to oblige everyone. To get an apprehension of what kind of grapple the operators wanted a formula with 18 questions was made. For the interviews 20 forestmachineoperators were choicest who had experience from Hultdins grapples, a lot of them also had experience from other grappleproducers and constructions.
The study showed that it is the durability the users give priority to.
