En jämförelse av krypteringsalgoritmer
Today the Internet is used more and more as a transportation for information.
Much of the information is confidential and should not be read by those not
privileged. To protect the information from unauthorized access cryptography
can be applied. The cryptography algorithms in use today all have their pros
and cons. They are therefore suited for different applications.
Traditional milk production in cattle in a semi-arid area in Kenya
Livestock of pastoralists provide meat, milk, blood, dung and are useful for transportation purposes. In semi-arid and arid areas with very low precipitation the herder must often walk far distances to feed the livestock. This affects the animals? production, especially of milk. Previous studies have investigated how to improve milk production in terms of milking strategies in cattle.
Implementering av tablets inom drift och underhåll av vägar : En utvärdering med förbättringsförlag
Implementeringen av tablets ämnade för inspektioner inom drift och underhåll av vägar har studerats och utvärderats med målet att fördjupa kunskaperna inom drift- och underhållsbranschen och skapa effektivare arbetsmetoder som gynnar alla byggprocessens parter. Examensarbetet är utfört hos Peab på deras anläggningskontor i Sundsvall och implementeringen har ägt rum på deras driftområde Sundsvall som består av cirka 122 mil statlig väg där Trafikverket är beställare. Genom litteraturstudier, tester av tableten och deltagande observationer så har tabletens användbarhet och utvecklingspotential analyserats och slutsatser har dragits för att ge Peab feedback på deras innovation med ett antal förbättringsförslag. Utvärderingen blev ej fullständig då Peab inte hann införa tabletsen inom vägdriften innan de 10 veckorna för examensarbetet var avslutade. Att använda tabletsen inom vägdriften kommer att effektivisera inspektionerna med dels digital dokumenthantering och det viktiga införande av GPS positionering i de fordon som utför inspektionerna. Detta kommer bli mycket smidigare än den tidigare arbetsmetodiken där i stort sett alla processer innefattande mycket onödigt pappersarbete. Peab rekommenderas fortsätta att se utvecklingsmöjligheter med tabletsen inom andra områden av vägdriften samt fullfölja utvecklingen av tableten för att få en användbar produkt. .
Att köra eller inte köra : En studie av miljömedvetna bilisters dissonansreducerande- och identitetsupprätthållande strategier
Att köra eller inte köra is a qualitative study aiming to show how environmentally conscious people who utilizes cars deal with their dissonant behavior, but at the sametime maintain an identity as environmentally conscious. The study is based on the fact that a third of those who drive cars in the municipality of Växjö would like to decrease their use of cars while at the same time having the infrastructural conditions to utilize other means of transportation. The study investigates inner obstacles in the form of habits and lifestyle, but also the different strategies the motorists use to reduce their cognitive dissonance and maintain a green identity. The indicators show that the reason the majority of the motorists continue to utilize cars is part due to inner obstacles (it's adeeply rooted habit, but also a big part of their lifestyles), part due to that the individuals have defenses for their use of their cars, defenses designed to have a dissonance reducing effect. The indicators also show that the motorists value their family higher than the environment, and in this way they can legitimize many of their car uses.
Säkrare arbetsmiljö med traktorer i vårbruket :
By doing this thesis I want to open up farmers and tractor drivers mind to see that there is
several risks with their work. There is a number of risks that everybody probably already
know about, and hopefully I will, with this work, help them to see a lot more risks, to make
them be more careful in the future. I?ve interviewed seventeen farmers in middle and south of
Sweden. I?ve also asked them for their opinion and what kind of changes they looking forward
to.

Optimerad lagerhantering
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.
Att göra en livsstilsförändring : Från kriminell till icke kriminell
The aim of this study was to investigate factors that ex-criminals believe have been of importance to them when they decided to leave a lifestyle of criminality behind. The study was based on eight semi-structured interviews with informants who had committed various forms of crime. Common to all informants is that they are now members in the Swedish association KRIS (In English: CRIS, Criminals Return Into Society), living a life without crime. The stories of the informants have been analyzed on the theoretical basis of social ties, the exit process, role loss, motivation and the life course perspective. Our study showed that the informants have been affected and motivated by various life events that could be identified and pin-pointed during the interviews.
Tillverkning av mikronålar för medicinsk tillämpning
Transdermal drug delivery, besides painfulinjections with syringes, has long been associatedwith small size particle pharmaceuticals, which candiffuse through the skin. This method of drugadministration has only been applicable on a smallnumber of drugs, where active molecules are smalland delivery time should or can be long.Other drug delivery options are oral administrationand injection with hypodermic needles (ordinaryhospital syringes). In oral administration thestomach and liver tend to dissolve the drug and theeffect becomes more difficult to anticipate, anddrug delivery rates difficult to control. Hypodermicneedles are used as a mean of drug injectiondirectly into the bloodstream. This method ispainful and risks infection due to tissue damageand skin penetration.One way to get a painless non-damaging techniquewith high delivery rate that still can delivery largemolecules is to manufacture an array of microscopichollow needles and equip them with a pumping unitthat delivers the correct amount of drugs.This thesis shows the technique and possibility ofmanufacture micromachined needles using low costtechniques of Ion Track Technology (radiation ofheavy ions creates porous materials), electrolessdeposition (non-current activated wet chemistrymethod of depositing metal) and electroplating.
Helandet av Stockholms sår : En analys av projektet Västra City
Over the years, what people have considered as the center of Stockholm City has gone from the medieval Stortorget in Old Town to the contemporary Sergels Torg. But more recently it has become unclear how the area really works. It is difficult to say where the actual central part of Stockholm lies, because while the Central Station is where the majority of people arrive into town, it is not necessarily close to Sergelstorg (considered the center of town) or other attractive commercial areas. There's also another issue with where the center of Stockholm is located. The railways and roads running along Klarabergs Viaduct acts as a divide between the areas of Kungsholmen and Norrmalm; these rails, roads and water separate the two areas from each other. In response to this problem of area division, a plan is being made to construct a new district near the center to mend the gap between the districts. The idea is that the center of Stockholm city will become more lively and attractive. The plan includes building new housing, commercial areas and a larger terrace called Mälarterrassen. In addition, improved mobility within the area is being planned by having better public transportation lines like City banan and tram named Spårväg City construction, as well as more pedestrian areas shall make the area become a district to thrive in.How the area will actually operate in the future is still unclear and many questions still exist about how the area will be able to compete and, above all, integrate with the other districts. The parts considered to be most important for the area is the scale of residential property and an attractive area that keeps people in the area and to encourages them to pass through the area. Perhaps the best solution would be to have something special planned in this area that can attract people in the community ? a city park, for example?.
Platsrelaterat själv och autobiografiska minnnen hos svenskar boende i Schweiz
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.
Vederlagsgrundande mätning med skördare
This study was performed in collaboration with Moelven Skog AB, Örebro district. The purpose of the study was to review existing literature in order to describe the current status of harvester based measurement technology as the way to provide information for calculating payment to the forest owners. In addition to this, a short survey was conducted to find out how a switch to harvester based measurement would affect the administrative workload on timber purchasers working for the district.
The literature study shows that the harvester measurement technology is ready to use if it is combined with well-established routines for control of the harvesters, methods for automatic quality indexing of the timber and ways of creating pricelists specially adapted for harvester measurement. Pricing each stem seems to be the most promising method. Stem pricing has several benefits.
[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.
