The Low Line : ett gestaltningsförslag med inspiration från The High Line
In the summer of 2009 the High Line opened in New York, a park built on an out-of use elevated rail viaduct. The park meanders its way through the buildings and allows the visitor to see the city from a totally different perspecive than we are used to.I have made a Design proposal in Eriksdalslunden, Stockholm, with inspiration from the High Line. The proposal is based on design ideas of a park I logically call the Low Line, as the place isn't elevated as in New York, but lowered. The two places have some similarities, mainly the strong urban identity and the tracks crossing both areas. They also have very obvious differences, above all the fact that Eriksdalslunden is situated in a swale and is defined in a third dimension by the high bridges that crosses the area.The High Line is designed by James Corner Field Operations, and they have been working using their motto 'Keep it Simple, Keep it Wild, Keep it Quiet and Keep it Slow' during the whole process, words that normally aren't associated to Manhattan.
Miljöledningssystem i små företag : vilka hinder finns och hur kan förenklade miljöledningssystem överkomma dessa?
Humanity?s increasing consumption has resulted in an increasing use of resources and thus an increasing environmental impact. Hence, the environment has become an important political issue. The increasing demands from stakeholders on companies to "green" their products and work internally with environmental issues makes it more and more important for enterprises to address these issues. Small enterprises constitute the majority of all enterprises and therefore they have a significant impact on environmental problems.
De behöver...mer från grunden : En kvalitativ studie om hur lärare arbetar med språklig medvetenhet i en klass med svenska som andraspråk
Background: The competition is getting harder between the universities. To reach the high school students and discover which means of contact they prefer and how they perceive student recruitment are important issues in order to succeed in marketing strategies.Purpose: The purpose with our report is to investigate, analyze and compare the student recruitment in three universities and investigate how the high school students want to be contacted. Then we compare to see if they think alike.Method: We have done a qualitative study and chosen to use focus group interviews for the high school students and interviews for the universities to collect our empirical data. We have compared the empirical data and analyzed it with communication processes and marketing communication as theoretical grounds.Result: All of the universities work approximately the same way with their student recruitment. They put a large effort in the Internet and social networks as well as the personal contact.
Heel Me
High heels ? a fashion that has not gone out of style after hundreds of years. Despite their esthetic advantages, high heels become uncomfortable and harmful after repetitive and long term use. With this as a starting point, Huyen Nguyen ? a student at the Innovation Engineering Program at the University of Halmstad ? decided to make a final thesis project.
The project goal has been to combine the esthetic advantages of high heels and bring a comfortable solution to the equation.

TILLFÄLLIGA EFFEKTTOPPAR I FJÄRRVÄRMEN : Kan man med hjälp av lagrad värme undvika att de uppstår i betonghus?
Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.
Oljetemperaturens inverkan på motoroljans degradering i lastbil
The market for heavy duty engines is constantly requiring engines that should be more andmore powerful, while still maintaining low fuel consumption. As a result of increasing enginepower, the engine and coolant temperature increases as well due to insufficient coolingperformance (because of design issues, cost etc.).Also, emission legislations, both current and future, require more and more measures to betaken by engine manufacturers. One way of meeting the legislations is the use of cooled EGR(Exhaust Gas Recirculation), which also lead to increased coolant temperatures.Both these factors also naturally lead to increased engine oil temperatures, the consequencesof which are not thoroughly investigated.This thesis project aims to investigate effects of high temperatures on engine oil degradation,with focus on the greatest degradation process: oxidation. To do this several engine runs havebeen performed on a 310 hp engine with EGR to see what happens to the engine oil in a realengine when exposed to high temperatures. During the tests oil samples have been taken andanalysed for important parameters.As a complement to these engine tests some laboratory oxidation testing have also beenperformed, to be able to compare engine test data with laboratory tests.One goal of the project was to try to formulate an empirical oxidation model, which would beable to predict oil oxidation levels in an engine, given any running parameters.
Automatisk bedömning av reglerkretsarsprestanda
In this thesis, a computer program that in a simple way can calculate the performance of control loops at the refinery Preemraff Lysekil has been created. The computer program has been adapted to the environment at Preemraff Lysekil. Theories for evaluation has been studied in aspect of reliability and of automatic implementation. The evaluation has been carried out from data collected directly from control loops at the refinery and from simulated control loops with implemented errors. Among the studied methods are Harris index and Stattin´s oscillation index.
Belöningssystem? hjälpande eller stjälpande? : En fallstudie om karriärreformen förstelärare på en gymnasieskola i Gävle
SAMMANFATTNINGTitel: Belöningssystem - hjälpande eller stjälpande? En fallstudie om karriärreformen förstelärare på en gymnasieskola i Gävle.Nivå: C-uppsats i ämnet företagsekonomiFörfattare: Alice Viklund & Erika LundströmHandledare: Monika Wallmon & Lars EkstrandDatum: 2015 ? januariSyfte: Syftet med studien är att med avseende på prestation och motivation skapa förståelse för hur de anställda upplever implementeringen av performance management i form av monetära incitament.Metod: Syftet med uppsatsen var att skapa förståelse för det rådande belöningssystemet och studien har utförts genom en kvalitativ metod. Data har samlats in genom semistrukturerade intervjuer med tio lärare på en gymnasieskola i Gävle. Därefter har vi genom tematisk analys presenterat materialet och resultaten i en slutsats.Resultat & slutsats: Slutsatsen vi kom fram till i vår studie var att karriärsreformen på kort sikt har skapat en något försämrad kollegial atmosfär och en känsla av orättvisa. Detta tror vi är mycket på grund av att belöningssystemet fortfarande är i en initieringsfas och att dessa reaktioner kommer att avta.
"Jag brukar jämföra källor med varandra." : En studie i gymnasieelevers kritiska tänkande
The main purpose of this bachelor thesis is to examine the existence of criteria and to what extent high school students use these criteria when they are collecting information for a school assignment. I also compare students attending different high school programmes with each other and compare students on different levels of education.I have done a quantitative study with 284 students in which the students have filled out questionnaires.The result shows that the most common way to evaluate information is to compare sources with each other. Students also look at how the information is written, and they want the information to be detailed and easily available. More seldom used criteria include consideration of the authority of the writer, determination of how up to date the information is, and gauging the perspective of the information.The result also shows that students attending a high school programme that prepares them for higher education are better at evaluating information than students attending a high school programme of vocational preparation. Students at a higher level of education are also better at evaluating information than students at a lower level of education. .

"Du pratar som dom i Sommarpratarna" : Om gymnasieelevers respons på argumenterande tal och attityder till respons
The aim of this study is to investigate oral peer review on argumentative speech and to study the attitudes towards this peer review. The investigation was performed in an up-per secondary school class, and it focused on the different types of oral responses students give each other. In addition, the study investigated in what way the students experience this type of peer review. The results show that students reflect on form and performance as well as content, but they place more emphasis on form and performance than content. Students are positive about peer review and its importance for their progress.
Elever och självreglerat lärande. : En studie om grundskoleelevers uppfattning om inlärningsstrategier.
Scientists and educational psychologists research have seen on self-regulated learning as learningconstruction. Every scientists have developed their own terms and concepts in the events of explaining how self-regulation affects students learning-process. Keyprocesses in previous studies is the importance of the active choice, to be goal-oriented,and awareness is what students need to self-regulate their own learning. The purpose of this study is to examine how students use different educational learning strategies based on the principles for self-regulated learning (SRL). From the process of the previous research, different concepts and terms have been divided into three key concepts titled:Active choices and actions, Goal-orientation and goal setting, as well as consciousness and self-awareness.
