Kartläggning av barn och ungdomar med cochleaimplantat (CI) med avseende på kombinerad syn ? hörselskada eller dövblindhet, diagnos rörande deras syn- hörselnedsättning samt frekvensen för uni- respektive bilateralt CI hos dessa barn och ungdomar
BackgroundThe opportunity for cochlear implantation has now extended beyond children who are only deaf or hard of hearing. Children who are deaf blind from birth or early in life are receiving implants, but very limited research has been done for this population, and this raises important issues. AimThe aim of this study was to estimate the prevalence of hearing and vision impairment or deaf blindness in children with Cochlear Implants in Sweden and to investigate the diagnoses issues among these groups of subjects. Material and MethodSubjects with an age between 1-18 years were ascertained through multiple sources and almost complete ascertainment was achieved.ResultsA total of 77 subjects with a referring diagnosis of combined hearing and vision disorder or deaf blindness were ascertained. Out of those, 30 subjects were excluded.
Power supply monitoring for wireless sensor platforms
Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.
OMBYGGNAD AV TRAFIKPLATS : Ekhagsmotet i Jönköping
We have the tradition in Sweden to build villas and houses with a wooden framework. It has become natural for us because we have so much forest in our country. Building with wood has advantages, it is easy to process, but also disadvantages, as it is sensitive to moisture.Finland has long made use of the thermal blocks to build villas. It is a type of bricks that are a bit like a sandwich element, with a core of EPS and concrete on both sides of the core material. The concrete is hollow, so that after the walls has been bricked up you pour concrete into the hollow bricks.The issue of this report is to find out if concrete can be an alternative to wood as framework material in villas.

Påverkan på elektronik och sensorer i radiologisk miljö
The objective of this thesis is to make a training material for KSU, which shows how radiation affects the different electronic components in a radiological environment.All electronic systems in the presence of high ionizing radiation can experience difficulties and be destroyed.This influence may compromise the control system and thus the safety of a nuclear reactor plant.To achieve this objective requires a description of electronic components and sensors, to better understand its function.This thesis will also show the possible solutions available that the author found interesting.Organizations such as NASA, CERN and ESA have worked to develop electronic components immune to radiation. Those organizations have also developed a test protocol that guarantees to a certain extent the security of electronic components in a radiological environment.Since we know how the material reacts with the radiation, it could develop a material that can be resistant to radiation or like CMOS technology has proposed, to reduce the component to avoid the storage of charge in the oxide.Another solution can be the GRAPHENE. Its features will revolutionize the electronics and provide answer to the radiation problems, Graphene will replace Silicium and the electronic components will only have a few nanometers dimensions so the oxide area also reduces, and in this way avoid the known problem of storage of charge..
Automatisk rengöring av Primary Charge Roller : Invegon Equip AB
Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.
Gynnar eller motverkar kommunerna kostnadseffektiv miljöstyrning : en studie av kommunala taxor och avgifter
Local charges may induce people to change their pattern of consumption by influencing investments and acts in certain directions. Some charges could for example give people incentives to use less natural resources. This study investigates four different local charges and whether they benefit an economical management with natural resources or not. This is carried out by investigating whether there is a polarity between local charges that may influence environmental actions or goods, and effective pollution control set to achieve certain nationally determined environmental goals.
The study includes two economic perspectives and investigates on the one hand whether local charges counteract governmental subsidies and on the other hand whether the charges vary between the different municipalities since large differences may lead to cost inefficiency.
Jag vill förstå dig. En studie om att använda bilder som ett alternativt och kompletterande verktyg i kommunikationen
Syfte: Syftet med denna studie är att undersöka bildens betydelse som ett verktyg, en artefakt, för att utveckla kommunikationen tillsammans med två elever som har diagnosen Charge. Syftet är också att personalen runt eleverna ska öka sin förmåga att se kommunikationen som redan finns och fungerar.Teori: Kommunikation, samspel och språk påverkar oss mycket i vår vardag. Grundsärskolans kursplan betonar att människan genom kommunikationen utvecklar sin identitet. Charge syndrom innebär för individen en svårighet i att samordna sina sinnen. Här talar man också om det proprioceptiska och det vestibulära sinnet vilka har stor inverkan på hur individen upplever sin egen kropp.
Att tala om Leviathan : Yttrandefrihet i konflikt med statens behov av skydd ? En fallstudie av åtalet mot Bradley E. Manning
This paper is a case study on Bradley E. Manning, famous for leaking classified intelligence to media, or in the charge sheet?s words: ?knowingly give intelligence to the enemy, through indirect means.? My opinion is that this sort of dilemma is a question of values, how you view the world and, most important of all, human rights and the philosophy of rights. Therefore I decided to sort out the arguments regarding the issue of freedom of speech versus the state?s need for protection.
PARS PRO TOTO? Tillgång till Internet som en del av tillgängligheten på sex folkbibliotek
Internet access has been a part of the range in public libraries for approximately a decade. The Swedish municipals, in charge of the public libraries, and the libraries themselves, have a great deal of saying in how they should be run, what to offer the public, how many hours they have to stay open etcetera. The Library law is very vague on many things, including public Internet access. Even though Sweden is ranked as first runner up worldwide when it comes to Internet penetration among the population (Internet World Stats 2007), approximately twenty percent in the 16-74 age group does not have Internet access at home, at work or at school (SCB 2006a). In this master thesis we try to determine, through personal interviews, how six of those in charge feel about Internet at their libraries, all located in medium-sized municipals (20 000 ? 40 000 inhabitants), why they have chosen the rules and regulations they have and their thoughts about what they consider to be the most important assignment of public libraries.
Optisk undersökning av dieselsprayer från en höghastighetsroterande insprutare
There have been changes in Earth?s climate system on both global and regional scale since the pre-industrial era and some of these changes are due to human activities such as the combustion of fossil fuels. This calls for the development of engines with a higher efficiency and less harmful emissions. One interesting concept is the Homogeneous Charge Compression Ignition (HCCI) engine, which has the advantages of potentially low emissions combined with high efficiency. However, HCCI with diesel fuel requires a relatively long fuel/air mixing time to ensure a "homogenous" charge.
Gratis i princip : Gratisprincipen och avgifter på svenska folkbibliotek : en enkätundersökning utförd på Norrköpings Stadsbibliotek och Eskilstuna Stads- och Länsbibliotek
The theme of this essay is the principle of free access to the Swedish Public Libraries, and its aim is to fmd out the opinion of adult visitors of such libraries as regards the introduction of fees on the borrowing of books, already existing fees such as reservation fees, charges for interlibrary loans and charges for the late return of books.The main part of our survey comprises questionnaires that were handed out to 100 visitors at the Norrkoping City Library and 100 visitors at the Eskilstuna City and Provincial Library. In order to illustrate the fee problem from another angle, interviews with staff people from the two libraries were carried out A large part of the essay consists of material aiming to give a general picture of the subject, e.g. how the "free of charge principle" is tied to the Swedish library system, what arguments have been presented to maintain or reverse this principle, and a comparison of the relative situation in other countries. As the conception of popular education is so basic for the "free of charge principle", we also account for the idea of popular education.The result of our questionnaire shows, among other things, that 60,9% cannot consider paying for any of the free services offer by the libraries today, 21,3% answered that they could possibly consider paying for some of the services and 17,8% answered that they didn't know. 76% would rather pay for a library card than stop borrowing books altogether..
Miljöarbete inom den civila luftfarten
The main environmental problem for aviation is the great amount of exhaust gases, mainly nitrogen oxides, carbon monoxide, carbon dioxide and hydrocarbons - mostly "greenhouse gases" leading to climate changes. I decided to sort out what is being done to decrease these problems and what regulations there are concerning air pollution by the means of searching the internet and using publications from aviation authorities for current figures. I chose to scrutinize authorities on political, authority and company level, resulting in summarizing the work of UN and EU respectively, ICAO (International Civil Aviation Organization), JAA (Joint Aviation Authorities) and LFV (Swedish Civil Aviation Authority), and finally SAS, representing the airline companies. Conclusion that I have drawn are thatthere are regulations for air pollution, written down in ICAO's Annex 16, that are to be followed. Secondly, LFV are environmentally controlling their nineteen airports and since economy is an important reason for not giving priority to environmental issues in aviation emission charge and noise charge are added to the landing fees.
När ett vallöfte blir verklighet : Analys av DN:s rapportering om fastighetsskatten innan och efter valet 2006
Did the mass media report in a different way about the real estate tax before the Swedish national election 2006 than they did after the election? If there were differences, what could be the cause?This study aims to answer these questions by using a quantitative analysis of articles about the real estate tax published in the Dagens Nyheter (DN), the biggest morning daily. The summer before the election, the ?Alliance?, (the non-socialist coalition, launched an election promise to abolish the real estate tax. Instead they planned to introduce a low community charge.The Alliance won the election and formed a government to implement their election promise. The analysis was made on all the published articles in DN that covered the real estate tax issue. In total there were 43 such articles. These where all published between the launch of the campaign promise until the electionday and a month before the proposal was launched 19/9 2007, until the proposal was implemented in 2008. The study results in three interesting conclusions.
Besökattraktionsutveckling i Fisksätra : En studie av intresset för ett nytt kulturhistoriskt besöksmål
Fisksätra has a historical background that goes back to the battle between Russia and Sweden that took place in 1719. This battle is known as "Slaget vid Stäket". Today there are plans to develop Fisksätra as a tourist destination where focus lays on the historic factor of the battlefield that took place there. As of this a project called the HAMN project has started to try to develop a new experience park at this destination unlike any other.The aim of this essay has been to study how much potential this experience park has to become a popular tourist destination in the future, while looking at the potential interest of the foreign tourists. This essay is written as an assignment for Göran Andersson, who is in charge of the tourism department at Södertörns Högskola.
