En utvärdering av två olika sa?tt att skatta fördelningen till stickprovsmedelvärden från olikfördelade data - normalapproximation kontra resampling
This report evaluates whether normal approximation or resampling is to prefer for estimating the distribution of the sample mean and functions of the sample mean. The evaluation relies on simulation studies. The observations of the sample are allowed to be differently distributed. In the case of sample means they are also allowed to be dependent.For sample means the two approximations behaves very similar. The most important component whether we have a good or a bad approximation is how good the approximations catch the variance of the true distribution.
Papperslösa barns rättigheter
This case study examines how upper secondary schools in a municipality in the northern parts of Sweden structure their special pedagogy with students who have ADHD and dyslexia, students? and parents? experiences of this, and what regulates the schools management in this particular aspect. The results show that all the schools have special pedagogues and other support staff employed, though in varied extent. Furthermore, the resources are distributed differently from school to school. The focus, however, is always around communication between the concerned parties.
Processoperatörens mobilitet -teknikstöd för mobil larmhantering
Processindustrin har möjligheten att ta steget in i en ny utvecklingsfas där
teknik kommer att spela stor roll. I och med att teknik allt mer stödjer
mobilitet öppnas möjligheten för processoperatörer att på valfri plats kunna
övervaka och styra tillverkningsprocessen. Med denna rapport presenterar
författaren sin empiriska studie på en högteknologisk fabrik. Studiens fokus
ligger i betydelsen av processoperatörernas mobilitet och hur den framträder i
deras arbete. Studien visar att mobilitet för operatörerna på fabriken är en
del av deras yrkesutövande och väsentlig för att kunna styra
tillverkningsprocessen.
Vikten av säkra nätverk
The purpose of this thesis is to show how to use vulnerability testing to identify and search for security flaws in networks of computers. The goal is partly to give a casual description of different types of methods of vulnerability testing and partly to present the method and results from a vulnerability test. A document containing the results of the vulnerability test will be handed over and a solution to the found high risk vulnerabilities. The goal is also to carry out and present this work as a form of a scholarly work.The problem was to show how to perform vulnerability tests and identify vulnerabilities in the organization's network and systems. Programs would be run under controlled circumstances in a way that they did not burden the network.
Undersökning av avfallshanteringssystem : För ett nyexploaterat område i Ekhagen, Jönköping
Outside of many Swedish households today, you will find a typical green wastecontainer. This container has not changed since its introduction, despitecomplaints about foul-smelling and its impractical system. Even if the system usedtoday, still is the most optimal choice, there is a lot of newly developedalternatives out there.Its purpose is to get a broader perspective on how a waste management systemcan be developed into a working, land efficiently and aesthetically pleasing systemof humans and the environment in a small residential area.The authors treat the residential area of Jära, Ekhagen, in Jönköping, which ismanaged by JM AB as a problem area in regards to waste management.The issues raised by the authors are the different waste management systems usedin the corresponding areas of the world, how to apply technical andenvironmental as well as the waste management facilities from financial aspects.In the process, the methods used were literature reviews, case studies and aninterview. The case study was done through a modeling of waste managementsystems in the area Jära and an interview was conducted with the company Envacworking with vacuum systems. Studies have been made by different systems n theareas around the world.The results show that using directives and guidance will reduce the environmentalimpact done without replacing the traditional system.
Optimering av reducerad bearbetning : högre skörd till lägre kostnad
Optimization of soil tillage and crop rotation is important in many aspects, but particularly in maximizing profit margins. Since the economic outcome is usually decisive, it can be interesting to study different combinations of soil tillage systems and crop rotations in order to identify the maximum economic outcome. How a crop functions in a particular tillage system determines whether it is profitable to grow that crop. Different tillage systems affect the soil and its processes in different ways. Reduced tillage often works best on weak-structured heavy clays and on silty clays.
Förslitning av fräsverktyg
Sweden is dependent on secure sea transport. Shorter disruption of imports of fuel and crude oil can be managed with an emergency stock, but a prolonged halt in imports creates problems. For industry, the vulnerability is greater. Fragmented production chains in combination with expenditure reductions in inventory causes a dependency on proper transport of intermediate goods in the manufacturing industry. A lengthy disruption thus involves disruption of production for both domestic consumption and for export goods containing imported parts.In order to secure shipping routes with a limited number of vessels, Mine Counter Measures (MCM) capacity is required, and according to the Armed Forces, developed with new sensors and autonomous vehicles.
Rektor - styrdokumentens förlängda arm i arbetet mot ?en skola för alla?
In 2005 we made a research in a Swedish community board about their view on the political and ideological intentions of ?a school for all?. The results from that study were the background to this research.The aim with this research was to find out how principles in the same community were thinking about ? a school for all? and if they were leading a development towards ?a school for all?. In that context they were given the opportunity to explain their definition and reasoning about ?inclusion? and ?integration?.

RTLS - real time location systems : an inventory study for agriculture applications and requirements
The trend towards increasingly large farming units raises questions regarding how to better monitor production. Larger units make the impact from possible errors more severe, which increases the pressure on management supervision. To cope with management issues, prevent errors and handle increased demands on traceability and documentation, the Real Time Location Systems (RTLS) concept is making its way into various parts of agriculture.
In sectors outside agriculture, RTLS are already being used successfully to track and locate items through nodes at different levels of accuracy, such as room level or the relative or absolute position. Empirical data can be received in real time from the nodes.
Genotype by environment interactions of claw health in Swedish dairy cattle in tie stalls and loose-housing
Claw diseases are common diseases in modern dairy production. They are painful for the cow and costly for the producer. Differences in the prevalence of claw disease depending on housing system have previously been observed. This raises the question if there are genotype by environment (GxE) interactions for claw diseases in different housing systems. To investigate this claw trimming records for Swedish Red dairy cattle (SR) and Swedish Holstein cows (SH) were retrieved from the Swedish Dairy Association.
Jag är ny här - får jag vara med? : En studie av nyanlända elevers sociala integration i skolan
The aim of the study was to evaluate the social integration amongst newly arrived students in the two different school systems Sweden welcomes them into. The first school system takes in newly arrived students into preparation classes whilst the other integrates the students directly into ordinary classrooms. The examination is based on qualitative observations in the classroom, canteen, and playground, and interviews with teachers and a select few students from each school system.The result of the study showed that newly arrived students in ordinary classes are socially integrated more into the school than the newly arrived students that are welcomed into a preparation class. Newly arrived students are offered a larger chance of being integrated into the school environment if they are introduced directly into an ordinary class. In preparation classes, social integration is narrowed down to between the classmates.

Information innanför murarna- en studie av fängelsebibliotekariers uppfattningar om informationsförmedling till interner
The aim of this study is to investigate variations of conceptions among prison librarians, concerning mediation of information from an ethical perspective. We have performed interviews with nine librarians and used the phenomenographic approach when analyzing the material. Sixteen categories of conceptions were found, distributed on four aspects of the phenomenon, the act of mediating information to inmates. The results show a variety of conceptions among the librarians. The four aspects cover conceptions about the inmates as users of the library services in prisons, conceptions about the information need of the inmates, conceptions concerning policies, guidelines and laws and conceptions about information access in the prisons.
