Vidareutveckling av provplattform för mätning av kosmisk strålnings inverkan på DRAM
Sammanfattning:
SAAB Communication i Linköping sysslar med konsultverksamhet mot ett flertal
nationella och internationella företag inom både den civila och militära
sektorn. Fokus ligger på flyget med uppdrag inom telesystem, radiosystem,
signaturanpassning, EMC, atmosfärisk påverkan mm. I det sistnämnda ingår även
kosmisk strålnings inverkan på elektronik. Den fortsatta miniatyriseringen av
elektronik, speciellt minneselektronik leder till ökad känslighet mot den
kosmiska partikelstrålningen som ständigt regnar ner på jorden, därför är det
extra noga att minnen testas innan de sätts i bruk vid flygburna system.
Syftet med detta examensarbete är att konstruera en provplattform som
registrerar fel som uppkommer i ett DDR2 SDRAM minne vid påverkan av den
ovannämnda strålningen. Detta examensarbete är en vidareutveckling av en
provplattform baserad på en FPGA ? lösning.
Konstitutionell nationalism i Östeuropa : En idéanalys av postkommunistiska konstitutioner i Östeuropa
This study focuses on nationalism in Central and Eastern Europe. Anchored in theories that this region historically has been characterized by a nationalism that is based on the ethnic group rather than on liberal or civic concepts, it is the purpose of this study to explore whether these theories still apply in recent times when the region has been liberalized, for example manifested in the entry to the European Union. The research question has been tested through analysis of the constitutions of a number of Central and Eastern European countries in order to investigate what type of nationalism that the states have codified in their basic political documents. The results show that some of the states give expression to the historical ethnic nationalism in their constitutions, which indicates that the theories still are relevant..
Canine S- and M/L- cone electroretinograms
Full-field flash electroretinography is an electrodiagnostic method used to examine the function of retinal cells. Light stimulation of the eye elicits electrical potentials in the retina. By aid of a corneal electrode and a reference electrode close to the back of the eye, the electrical potentials can be recorded and presented as an electroretinogram (ERG). ERGs driven by mainly one type of cones can be used to examine the function of a single cone class. In human beings, studies have shown the cone class sensitive to light of short wavelengths, the S-cones, to be more vulnerable to acquired damage than the other cone classes (Daley et al., 1987; Gouras et al., 1993; Greenstein et al., 1989).
Dogs have two cone classes, S-cones, and M/L-cones (most sensitive to medium to long wavelengths).
Development of a method for determination of pesticide residues in honey using liquid chromatography tandem mass spectrometry
Honey is a product that may contain pesticide residues due to contamination from bees pollinating various plants as well as elimination of vermin inside the hive. Different methods are needed for analysis of pesticides, since the term includes a wide range of different substances. National Food Administration lacks a validated method for determination and quantification of pesticides in honey using liquid chromatography tandem mass spectrometry, LC-MS/MS. The technique is especially important in analysis of polar and non-volatile pesticides, where gas chromatography is not functioning optimally. After investigating what pesticides could be found in honey produced in Sweden, a number of four pesticides suitable for analysis with LC-MS/MS was compiled; boscalid, impidacloprid, tau-fluvalinate and thiacloprid.
Manliga förebilder inom socialt arbete : föreställningar, praktik och organisation
Among those who graduate from the various schools of Social work in Sweden are a great majority women. At the same time men are sought after in the work field. But not just to level up the equality between the sexes, but also to fill a gender specific niche to counter up a need for male role models. But a closer look at this need and the types of functions set to cater for it shows that male role models as a concept vary between contexts. In this study we examine the concepts and the practices of male role models in three different settings: a municipal social care center offering young boys male bonding activities; a non-profit organization warding young people from drug abuse and criminal behavior; and last, a long term residential home for young boys between the ages 13 and 19. Our research shows that the concept of the male role model vary between the organizations and less so within.
Det blänkte som av silver i jorden : En studie av den glimmermagrade keramiken i Norrland under bronsålder och äldre järnålder
As to now, no study has been made of the mica tempered pottery found along side the asbestos tempered pottery in Norrland during the Bronze Age and Early Iron Age. Its occurrence has previously only briefly been noted in a few published works and the dating and geographical distribution of mica tempered pottery in the north of Sweden has to a large extent been unknown. This paper aims to compile the available information about this type of pottery and the locations where it has been discovered in order to date and explain the occurrence of mica tempered pottery in Norrland. It's also suggested that the occurrence of mica tempered pottery is connected to the spread of the early metalwork from the east to areas that today makes up the north of Norrland..
BeAKKta - ett kommunikationshjälpmedel som möter behoven av djupare kommunikation hos personer med autism
A vulnerable group in society is people with ASD (autism spectrum disorders) or
autism. This group seems to increase, mainly due to genetic factors but also
environmental problems. Medical research has accelerated in the U.S. and
Europe. The biggest problem for people with disabilities is the inability to
communicate, both verbally and socially.
Value-at-Risk : Historisk simulering som konkurrenskraftig beräkningsmodell
Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.
Svenska fastighetsbolags resultat samt kassaflöde för och efter införandet av IAS 40
The connection between accounting and taxation goes back to the 1920s laws of the named areas. A proposal has now been brought forward, the so-called SamRoB-investigation, which means that the connection between accounting and taxations should be decoupled.The authors? aim with the study is to investigate what a possible decoupling between accounting and taxation, i.e. the formal connection and the untaxed revenues, implicates for the auditor´s work.A research has been done by interviewing two authorized auditors and one authorized consultant of accounting to get a view in how the auditor?s works could be affected.
Print quality study of a laboratory offset press
PAPRO operates within the Forest Research company and their mission is to develop value-addingindustry solutions. At present there are no good ways for mills to easily test the printing quality on newsprintpaper. There is a great need for a fast way to do this on different paper qualities; with a laboratory-offset press this can be both a time and money saving method. At PAPRO Forest Research, NewZealand, a laboratory offset press has been developed and designed, during the past seven years, concerningthis issue.

Innovation på Itkonsultföretag. En fallstudie på EVRY
Companies today are exposed to a turbulent market with fierce competition and the ability toinnovate itself becomes increasingly important. But what innovation is and how it is managed is farfrom obvious. In this case study at EVRY the research questions are: ?What is innovation in ITconsultant companies?? and ?how can innovation be managed in IT consultant companies?? ITconsultancy is a complex type of business and their focus is often to innovate the customers businessrather than their own. The study is based on a literature review, field studies, unstructuredinterviews and an interpretive analysis.
Skönlitteraturens kraft : En analys av framställningen av psykisk ohälsa i två romaner ur ett interkulturellt perspektiv och ur ett genusperspektiv
This paper is written in the field of Educational Science, and it focuses on literature that pupils read. Literature has the power to shape readers beliefs, that is why this paper aims to examine, and compare two novels that are used in Swedish schools in class settings. Both novels deal with the issue of psychiatric disorder from a woman´s perspective. Research done in the field of psychiatric disorder shows that it is an important subject that should be addressed in schools. Research done from the perspective of gender studies points out the need of representation of female perspective in literature that pupils are working with.
Spår av autism i Czeslaw Milosz Issadalen - Traces of Autism in Czeslaw Milosz Valley of Issa
The partly autobiographical book Valley of Issa, written by Czeslaw Milosz describes (among other things) the childhood of a boy, Tomasz who is the main character, and his interactions with his relatives. In this essay I will claim that these characters possess startlingly obvious autistic traits, and in relation with this I raise and discuss another question: Does the author Milosz himself express autistic traits? My essay could hardly constitute a complete analysis with definite answers, (the bachelor format of the essay and the fact that Milosz is dead limits more extensive investigations) and I do not mean to claim that Milosz was a sick person, even though I may suspect it. Let this essay be an eye-opener and a visionary foundation for new approaches to Milosz authorship. The value of it lies in its approach.
Biggi förvaring : förvaringsskåp för utomhusbruk
Manne Bouveng, CEO of Optimel AB had an idea for a new kind of storage cabinet that could be adapted especially for townhouse owners. I came in contact with Manne by a familiar friend for us; we met and decided that it would suit as my thesis.What was needed to be done was a market research that would possibly show that there was a need for a new kind of storage cabinet on the market. Because of this we continued to work on the basic idea. We came up with a solution where we developed a box that resembles Optimels known mailbox Biggi Rondo, the storage cabinet is a new solution of a storage cabinet, adapted after a market that need of a lot of new space. The solution is based on a simple construction which sits an inside hang-off device which can attach tool hooks, tool holders and shelves and so on.The purpose of the assignment was to develop a new type of storage cabinet with some kind of solution to attach tools and other garden related stuff. With this we have succeeded and the concept meets the requirements we set ourselves at the beginning of the project..
Social Demokrati : Sociala medier, Politiker och Demokrati
The aim was to explore how the first page of a student newspaper has been changed over time since it was founded in the 1960´s.This thesis explores how the front page of the student newspaper Lösnummer has been changed since it was founded in 1966. It concerns the location and frequency of elements and it is based on theories of layout, the first page and visual communicationIn addition, the thesis develops a new kind of method for determining the location of elements on the type area. The method is based on the hexadecimal number system. It is formed as a grid which is placed on the first page to determine the location of the elements.It concludes that the frequency of elements had its peak during the 1970´s and has ever since decreased gradually. Image placement has gone from being scattered all over the front page to be centered and increase in size. .
