Bedömning av utländsk brytning och förståelighet hos personer med svenska som andraspråk före och efter en kurs i svenskt uttal
There is a lot of research made on second language (L2) learning (Jesney, 2004). However the relationship between foreign accent, intelligibility and acoustics within pronunciation tutoring is quite an unresearched area (Thorén, 2008). The aim of the study was to analyze how a course in Swedish pronunciation affected foreign accent, intelligibility and acoustics among L2-learners of Swedish. A total of 41 people participated in the study: 16 L2-learners, 4 native Swedish speakers consisting a control group and 21 perceptual assessors with Swedish as native language. The L2-learners foreign accent and intelligibility were rated by the listeners before and after a course in Swedish pronunciation on an eight-point Likert-scale.
Kapacitetsinvestering i kopplingsaxeltillverkningen på Volvo
CE
Examensarbetet har utförts på Volvo Construction Equipment AB Component Division i Eskilstuna. Företaget tillverkar drilvlinekomponenter till bland annat hjullastare och ramstyrda dumpers. Företaget befinner sig i en expanderande fas med ökande volymer och på vissa håll har taket för bearbetningen nåtts. Kopplingsaxeltillverkningen är en flaskhals i företaget och behöver ses över för att möta de ökande volymerna. Uppgiften har bestått av att utforma en ny layout till bearbetningsgruppen för kopplingsaxlar.
Noggrannhetsanalys hos mätmetoderna; RTK-mätningmed SWEPOS tjänst, GNSS-mätning med egenbasstation, laserskanning samt mätning medtotalstation.

Validering av Casmo-5M / Simulate-3
The objective of this M. Eng. Diploma work was to validate the new version, CASMO-5M, and compare the results with CASMO-4E, by using the same input in both programs. The tasks that were included in this work was to compare TIP-measures, k-effective curves (warm), k-effective curves (cold), the effect of void on k-effective, the isothermal temperature coefficient (ITC), the moderator temperature coefficient (MTC), damping ratio calculations, internal effect in a fuel bundle of a BA-rod, the speed of BA-out burn, impact of xenon, falling control rod, margins and isotopes.The TIP-measures showed that the differences were small for all reactors, at most, 6% nodal improvement by C5M (Casmo-5M) for Oskarshamn 3. The warm measurements of k-effective showed that C5M had a higher value for all cycles of Oskarshamn 1, 2 and 3 in comparison to C4E (Casmo-4E).
Automatisk detektering av akustiska resonansfrekvenser i trästockar
In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.
Svinnoptimering VTIS1
The goals of this Bachelors? Thesis were to establish the production loss through the VTIS1 Pasteur at Arla Foods Linköping dairy and then suggest simple but effective solutions to minimize the losses for each production run. If the timeframe allowed it, some of the solutions would be implemented and tested in full production to determine their impact on economic and environmental savings.The very first step of this project was to establish the statistics over what losses there is in the production pipeline through VTIS1, from milk and powders in mixer tanks to finished and packed products in cold storage. Then, when knowing how much product was actually lost and where, those bottlenecks could be pinpointed and examined more closely. At this stage the focus was switched, from the otherwise complicated and broad manufacturing process, to the VTIS1-aggregate, since early data indicated there were quite substantial losses there.In conjunction with this project Arla Foods purchased an absorption photometer-measuring device (OPTEK AS16) that could be inserted straight into the product stream out of VTIS1, allowing real time measurements of its optical density.
Kan omega-3 förebygga uppkomsten av allergi?
Sahlgrenska Academy at University of GothenburgDepartment of Internal medicine and Clinical nutritionAbstractTitel: Can omega-3 prevent the emergence of allergy?? A systematic reviewAuthor: Karin Andersson and Cecilia BjörertzSupervisor: Henriette PhilipsonExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 hpType of paper: Examination paper, 15 hpDate: 2012-05-23Background Today allergy is a major public health issue and one of our most common chronic diseases. It would be most profitable if there was a way to prevent the emergence of allergies, both regarding the community and the individual. The antiinflammatory property of omega-3 influences the immune system and is thought to have a preventive effect on allergic symptoms. To investigate whether the mothers intake of omega-3 during pregnancy and lactation affects the child?s future development of allergy is therefore of high interest.Objective To examine if omega-3 supplement given to mothers during pregnancy, or pregnancy and lactation, is shown to be beneficial in children with heredity to develop allergy.Search strategy Articles were collected from the data bases PubMed, Cochrane and Scopus.
Implementation av ett interface till Emotiv Epoc
The eld of Brain-computer interfaces (BCI) concerns linking together an external device with the brain of a human or an animal. By doing this the conventional use of a mouse or keyboard can be circumvented, which can greatly benefit people with different types of diseases that cause paralysis or other loss of motor control, such as Amyotrophic lateral sclerosis (ALS). A BCI can also be used for cognitive training of either healthy or mentally impaired subjects to increase cognitive capabilities.In this thesis an implementation of an interface is made against such a device, the Emotiv EPOC Headset. The result is meant to be a stable basis for further study using the device. An in-depth study of the history of EEG and its current use in clinical work and research in the topics of BCI as well as Human-computer interaction (HCI) is presented.

Validering av RAADS: ett självskattningsinstrument för vuxna med misstänkt autismspektrumtillstånd
Trots vetskap om att den kliniska bilden vid autismspektrumtillstånd (AST) förändras med åldern råder det brist på diagnostiska instrument som är specifikt designade för vuxna. Ritvo Autism and Asperger Diagnostic Scale (RAADS) är en självskattningsskala utvecklad för detta syfte. Den svenska versionen av RAADS utvärderades i föreliggande studie med avseende på intern konsistens, diagnostisk validitet och samtidig validitet. Undersökningsgruppen bestod av 75 individer med högfungerande AST samt 200 kontroller utan AST. Därtill utfördes en preliminär analys av resultatens stabilitet över tid.
Miljöanpassad offentlig upphandling : en komparativ flerfallstudie av regionala handlingsprogram för miljöupphandling i Spanien
In Europe, the central governments are the ones to coordinate the international standards and strategies regarding GPP; Green Public Procurement. However in Spain a GPP program was introduced late and only applied to the Central Government Institutions, (AGEA) (BOE nr. 027, 2008). These means that smaller administrations, such as, Autonomous Regions, Municipalities and Town Councils were not included in the program. The absence of a national program which excludes those governments made them introduce their own criteria for GPP, and the difference in criteria varies from one government to the other.
Annonsmediers miljöpåverkan : när ska miljön få en reklampaus?
The aim of the thesis was to investigate energy consumption and carbon dioxide emissions from an advertisement broadcasted on the radio or the television or
distributed through press. The object was to calculate the amount of carbon dioxide emissions per individual receiver of an advertisement in Sweden. There was no room
for a deeper investigation into editorial work within the framework of the thesis.
Consequently, main focus of the radio and television study was on broadcasting itself and the components involved. Focus for the press study was on paper production,
printing and distribution. Production and discarding of media equipment was not taken into account.
Mobilapplikationer - Framtidens väg till kundlojalitet?
Utvecklingen på den teknologiska marknaden har kommit att påverka företag i en allt större utsträckning då marknadsföring på Internet blivit allt viktigare. Den ökade använd-ningen av smartphones har bidragit till att fler och fler människor ständigt är uppkopp-lade vilket i sin tur har öppnat upp för nya sätt för företag att skapa relationer och att inte-ragera med sina kunder. En bidragande faktor är sociala medier som har öppnat upp för interaktion där företag och kunder kan kommunicera med varandra. De har även öppnat upp för kommunikation kunder emellan, vilket både skapar positiv och negativ word of mouth. I takt med utvecklingen av den nya telefonin, har mobilapplikationer kommit att få en allt större betydelse som marknadsföringskanal.
Facilea : hjälpmedel för hemtjänsten
With help from Hälsoteknikcentrum the need for storage of medical items in the home care section has come to our attention by an investigation that Hälsoteknikcentrum did. Facilea and the nursing stuff at Eketånga home care have developed a product specified to improve the work situation for both the nursing staffs and the patients.The trolley is equipped with a special module to make the trolley more adjustable for the recipients and the nursing staffs needs and desires. The product also collect all the care items in one place. Which gives the care patient and its relatives a possibility to gather all the medical items in one place and don?t have to put these in bookshelves etcetera.After surveys, interviews and home visits a prototype was built.
Algoritm för automatiserad generering av metadata
Sveriges Radio stores their data in large archives which makes it hard to retrieve specific information. The sheer size of the archives makes retrieving information about a specific event difficult and causes a big problem. To solve this problem a more consistent use of metadata is needed. This resulted in an investigation about metadata and keyword genera-tion.The appointed task was to automatically generate keywords from transcribed radio shows. This included an investigation of which systems and algorithms that can be used to generate keywords, based on previous works.
