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.

Experimentellt vidareutvecklad modell för dimensionering av skadebegränsandeåtgärder mot RSV-penetration vid ammunitionsröjning

Vid röjning av RSV-ammunition saknas idag adekvat beslutstöd för att dimensionera skadebegränsande åtgärder mot jetstrålens verkan. I uppsatsen vidareutvecklas en beräkningsmodell som författaren tidigare föreslagit. Syftet är att skapa ett verktyg som kan införas i ammunitionsröjningsverksamheten.Fullskaliga skjutförsök har genomförts för att klarlägga inverkan av förhållanden som är typiska vid ammunitionsröjning; en skyddskonstruktion byggd av sandsäckar och med ett långt detonationsavstånd till röjningsobjektet. Försöksresultatet visar att den grundläggande hydrodynamiska penetrationsteorin inte är användbar för dessa förhållanden. Vidare ger sandsäckskonstruktionen signifikant bättre skydd mot jetstrålen än en homogen grusbädd.Genom störningsanalys har känsligheten hos de enskilda parametrarna i beräkningsmodellen för verksamhetstypiska fel utretts.

Finkalibriga projektiler, RSV och penetrerande stridsvagnsminor : vad krävs av ett ballistiskt skydd för att undvika penetration från dessa stridsdelar?

Detta arbete syftar till att undersöka vilket konventionellt ballistiskt skydd som krävs för att undvika penetration från finkalibriga projektiler, RSV-stridsdelar samt penetrerande stridsvagnsmina. Arbetet tar sitt ursprung i en handbok utgiven av FMV där stridsdelar som kan förekomma i Afghanistan behandlas. Handboken anger data och prestanda för dessa stridsdelar och det är därifrån arbetet tar uppgifter om genomslagsförmåga för stridsdelen. Skyddsprinciper och verkansprinciper för stridsdelar hämtas i huvudsak från rapporter utgivna av FOI samt från litteratur utgiven av FHS. Arbetets beskrivande delar inleds med en redogörelse för homogena ballistiska skyddsmaterial av metall samt keramer.

The Relationship between Internationalization and Firm Performance

Title: The Relationship between Internationalization and Firm Performance Seminar date: 5 June, 2008 Course: Masters thesis in Business Administration, Programme for Managing People, Knowledge and Change, 15 University Credit Points (15 ECTS). Authors: Cheng Hsun Chiang and Márton Pap Advisor: Dan Kärreman Key words: Internationalization, Performance, Multinationality, Degree of Internationalization (DOI), Country of Origin Purpose: To illuminate various crucial aspects of internationalization by systematically contrasting the different models of the multinationality-performance relationship and searching for underlying reasons. Methodology: Meta-analysis on previous theoretical and empirical research. Our emphasis in this paper has been put on the qualitative aspects of the previous research unlike many other conventional meta-analyses that focus on the comparison of the empirical data. Theoretical perspectives: Five main models have been developed by earlier studies to describe the relationship between internationalization and performance: positive linear, no or ambiguous relation, inverted U-shaped, standard U-shaped and S-shaped curve.

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.

Den avgränsade krisen : En gränsdragningsanalys av Lindbeckkommissionens rapport Nya villkor för ekonomi och politik (SOU 1993:16)

During Sweden's economic crisis in the early 1990s a governmental committe of prominent economic and political experts were gathered to produce an analysis of and suggestions to the solution of that crisis. The committe produced a report that became widely commented in the media and in parliment. The report anc the reception of it gives us insights in how the boundaries between social science and politics are created an how new fields of expertise is added to a science. This thesis uses a constructivist approach to explore how the techniques of the economic science were made into credible means of knowöedge production outside of the field where it traditionally holds epistemological authority. Working from the assumption that language does things to the objects that it describes I claim that the episode investigated in this thesis was shaped by the committee's ability to define the economic crissi and thus making it into a knowable object.

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.

Yttre gestaltning för upplevelse inifrån

The report aims to show how outdoor environments have been shaped with the purpose of experiencing them from the inside of buildings, through an overview perspective. Two Danish gardens are used as examples. One is the Baroque garden in the garden of Frederiksborg castle in Hillerød. The Baroque garden is thus a part of a larger garden. The second garden is the Charlotte Garden, a relatively newly constructed garden within a housing complex in Østerbro in Copenhagen. Both gardens are analyzed on the basis of visual expression and structure. In the report, it is also discussed how the contemporary society have evoked the different ways of shaping the gardens.

Socionomprogrammet- en praktik inom forskningsyrket?

Social work has gone from being a primarily philanthropic issue to becoming an academic discipline at university level. To ensure its legitimacy social work must be founded on, and developed through scientific research and documented experience. The purpose of this essay is to review the various arguments on social work in order to evaluate their impact on education, which in turn affects students. In addition, it will demonstrate how different forms of knowledge are valued depending on the contexts. As a means of reaching this objective, the following questions are addressed: ?What are the requirements and recommendations on how the education of social work should be structured, and why are these requirements and recommendations important??, ?How has the education of social work been influenced by the perception of valuable knowledge?? and ?How does the education of social work affect students?? The collected material consists of various arguments concerning the development of social work and the education of social work's formation.

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.
