Detta examensarbete har gått ut på att finna en ny konstruktionslösning på uttlopps-diffusorns inloppsrör på gasturbin SGT-800. Arbetet har utförts på Siemens Industrial Turbomachinery AB i Finspång på avdelning RCTD (gasturbinkonstruktion).Målet med projektet har varit att ta fram en konstruktionslösning som underlättar för svetsmontörerna på site när det gäller installation av inloppsrören, samt reducerar monteringstiden. Målet har även varit att ta fram en kostnadsjämförelse för totalkostnaden mellan den nya och originalkonstruktionen.Den metodik som har använts till detta arbete är Voice of the customer samt Systematisk konceptutveckling som baseras på bl.a. Vladimir Hubkas princip. Även original-konstruktionen har undersökts via ritningar och bilder tagna från tidigare sitemontage.Originalkonstruktionen skickas idag till site omonterad tillsammans med utlopps-diffusorn direkt från SIT AB:s underleverantör KSG AB i Surte för att sedan monteras och svetsas fast på site.

Huvudsyftet med denna uppsats är att undersöka effekterna av aggressionsersättningsträning (ART) program på tre kriminalvårdsanstalter och två frivårdskontor. Huvudfrågeställningen som belyses i studien är: förändras deltagarna i ART-program med avseende på empati och attityder till kriminalitet? För att besvara dessa frågor har vi utfört för- och eftertester på tre kriminalvårdsanstalter och två frivårdskontor. Instrumenten som användes i testerna är Davis Interpersonal Reactivity Index (IRI) och Mill's Measures of Criminal Attitudes and Associates (MCAA).Slutsatserna som kan dras utifrån denna studie är att den emotionella empati-komponenten "personal distress" visar en minskning som kan förklaras av interaktionen med ART.The aim of this study is to investigate the effects of Aggression Replacement Training (ART) program in some of the prisons and probation authorities of the Swedish correctional system. The specific questions we are trying to answer are: (1) does ART-program change the clients' empathic concern and (2) does ART-program help in changing participants' attitudes towards criminality? This investigation is based on a quantitative inquiry consisting of Interpersonal Reactivity Index (IRI) and Measures of Criminal Attitudes and Associates (MCAA) tests.The overall results of this study indicate that the emotional empathy-component "personal distress" shows a statistically significant reduction, which can be explained by the interaction with ART..

The aim of this thesis is to examine the possibilities and challenges facing an archive, Svenskt barnbildarkiv (SBBA), if to publish its material online. Our context for this study is image indexing. Our main questions are: How can SBBA index their pictures for a possible publication on the Internet? Are there any pros or cons in the determination of topics in children?s images, and in that case, which? What search paths are important when indexing children?s pictures, and why are they important? To answer these questions, the thesis is built on a wide study of interdisciplinary literature. But also on SBBA: s own handbook for image ?registration?, and on interviews with the persons working at the archive SBBA, in Eskilstuna.

Image indexing research today is either conducted on a visual attribute level or on a higher semantic level, forming a semantic gap between the two. There is much to gain if research progress from the two fields is combined. Image retrieval using access points in both visual and semantic significations could improve retrieval and bridge the gap. In social media today, images are often the primary communication agent and the number of images on the web is increasing in an uncontrolled way. New and efficient ways to index and retrieve the images are needed.The purpose of this study is to examine if emotions could be a semantic access point for image retrieval and if folksonomy indexing is useful when searching for images that represent emotions.

Övervikt och fetma är ett snabbt växande folkhälsoproblem som medför ökad risk för psykosocialt lidande och många allvarliga sjukdomar. Särskilt oroande är att övervikt och fetma allt oftare drabbar barn och ungdomar. Syftet med denna studie är att undersöka om det finns ett samband mellan Body Mass Index (BMI) och Känsla Av SAMmanhang (KASAM) hos elever i skolår 9, samt att analysera kön och psykosociala faktorers (familje- och kamratrelationer) eventuella inverkan på relationen BMI och KASAM.Det statistiska materialet är hämtat från undersökningen ?Liv och hälsa - Ung 2004 Västmanland? där KASAM- skalan med 13 frågor används. Analysmetoden är en multipel regression.Resultaten indikerar svaga samband mellan variablerna.

Interest for Mutual funds has been enormous in Sweden and since 1970 has savings increased from 300 million SEK to about 900 billion SEK. An important reason for this increasing is the strong development of the stock markets has got and, the impairment of the public pension and the increasing of necessity of the private saving..

Today´s roofing of dwelling houses is a very time consuming procedure, which includes a lot of different steps on the construction site. Not only does it cost a lot of money, but often do problems with rot and mold occur in the attics of houses today. The use of prefabricated modules has seen a great breakthrough in the field of construction of dwelling houses; at least when it comes to foundations and walls, where this type of approach makes the construction process way more efficient. What no one previous has succeeded to develop is a corresponding system for roofs that meets the demands of a dwelling house. Accordingly the goal of PlusTak has been to come up with a proper module system for roofing of dwelling houses, where the roofing is completed to meet the demands of the Scandinavian market. During the project a lot of effort has been put into customer contacts and the usability of the product, as well in the manufacturing process as on the construction site. This development has gone hand in hand with several practical tests and tryouts.

The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.

To investigate effects of nitrogen on in-lake CO2 and CH4 production during winter, three pair of lakes was subject for a fertilizing experiment in which one lake in each pair was fertilized with nitric acid (HNO3) directly into the water column in the summer of 2012. The lakes in each pair are assumed to be morphologically, hydrologically and biologically similar, that is, the non-fertilized lakes are considered references. The pairs do differ in one major way by being progressively less humic, going from around 25 mg/l to 10 mg/l DOC. Sampling and analysis was carried out at the end of the frozen period in 2013. Results show a significantly higher concentration of both CO2 (p<0,001) and CH4 (?=0,1, p=0,053) between impact and reference sites in the two less humic pairs.

I Västerbotten täcks den produktiva skogsmarken till 44 % av tall. Tallar bildar kärnved, men anledningen till detta är fortfarande oklar. Det antas dock innebära fördelar att bilda denna typ av ved. Kärnved består av döda parenkym och epitelceller, medan splintveden innehåller levande celler. Kärnveden innehåller även olika typer av extraktivämnen samt fenoler.

This study was carried out at the request of the Swedish forest company Sveaskog which is an important producer of logging residues (branches and tops) intended for energy production. The company wanted to increase the average dry content to 60 percent in their delivered logging residues. At the time when this study was initiated, the dry content in the chipped logging residues originating from the Bergslagen district was at 52 percent. The aim of the study was to find out how windrows of logging residues could be arranged in order to help obtain desired properties such as increased dry content. Sveaskog had developed a system for evaluation of windrows and a standardized form was utilized to describe different properties of the windrows.

Effects of climate change, urbanization and global homogenization are resulted in the degradation of land and losses of natural habitats. Ecological design integrates nature into urban environment by respecting natural ecological principles and processes and creating resilient urban biotopes which also can be used by local urban communities. The aim of the thesis is to answer the research questions: How ecological design principles can be applied for re-design of Toledo Riverfront (with requirements of the design competition)? and What is the ecological design in landscape architecture? I participated in the USA design competition with the aim to create a vision and redesign of Toledo Riverfront in Ohio State, USA. The site is located in the south point of Lake Erie. As a result of a long industrial activity, riverfront of Toledo had been transformed into inaccessible and abandoned brownfields. In my proposal I applied ecological design principles on three scales: the city of Toledo by reinforcing of ecological connection and creating green corridors along the river; the intermediate scale by suggesting public parks along the river front and on the fine level by proposing detailed design including remediation of the site and use of dredged material.

Institutionen för datavetenskap (IDA) vid Linköpings universitet har tillsammans med försvarsmakten, polisväsendet och räddningsverket i Östergötland startat en projektstudie för att utröna huruvida augmented reality-teknik (AR) kan användas för att förbättra koordinationen mellan civila och militära organisationer, och på sikt även militära och civila organisationers gemensamma stabsarbete mellan nationer. Kunskap om hur militära och civila organisationer - som har ett tätt samarbete vid olika former av samhälleliga kriser - ser på sin organisationsspecifika teckenanvändning kan vara relevant vid införandet av ny teknik. Detta i synnerhet om det går att finna skillnader i de olika organisationernas syn på och användning av tecken.Denna studie har gjorts i anslutning till ovanstående projektstudie och fokuserar på hur företrädare från försvarsmakten, polisen och räddningstjänsten, utifrån en semiotisk inramning, ser på sin teckenanvändning. Syftet är att undersöka ifall betydande skillnader i teckenbruk finns hos dessa organisationer. För att nå en större inblick i hur företrädare för de tre organisationerna ställer sig till den egna teckenanvändningen har utdrag ur ljudinspelat material från två olika sessioner analyserats.

On-site sewage systems are common on the countryside of Sweden with approximately one million on-site systems installed. Due to insufficient function, these contribute significantly to the total discharge of phosphorus to rivers and lakes, causing eutrophication. In order to reduce eutrophication and to fulfil one of the environmental quality objectives, the decision was taken by the Swedish Government in 2005 that 60 % of phosphorous in sewage sludge is to be recycled to arable land before 2015. To make recycling a reality, new solutions have to be found. Federation of Swedish Farmers (LRF) takes an active interest in this issue and has initiated this study. One problem is that the food industry is sceptical towards recirculation due to the risks that products from sewage systems may contain pathogens, heavy metals and unwanted chemical compounds, e.g.
