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.

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.

Opartiskt berättande : En ny mall för dokumentärfilm

Det är mycket svårt, om inte omöjligt att göra en opartisk dokumentärfilm. I minundersökning skapade jag en särskild mall som jag sedan följde då jag genomförde endokumentärproduktion. Mallens innehåll är baserat på teoretisk forskning jag gjortinom dokumentärteori och hade som mål att eliminera de största faktorerna sombidrar till det till synes omöjliggörandet av opartiskhet. En viktig del av den teoretiskaforskning jag gjort är de teorier Stella Bruzzi ställer angående performance. Jag valdepolitik som ämne för min produktion i hopp om att få två polariserade åsikter om ettämne för att därmed utmana regissörens opartiskhet så mycket som möjligt.

Värmeöverföring i bergvärmesystem : En numerisk analys av den ringformade koaxiala borrhålsvärmeväxlaren

The borehole heat exchangers of today suffer from poor thermal and hydrodynamic performance. The purpose of this thesis is to improve the performance of ground source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal and hydrodynamic performance. A model has been set up in the program Comsol Multiphysics in order to investigate the heat transfer characteristics along the borehole.

Från elev till student : En jämförelse av tre högskolors studentrekrytering och gymnasieelevers perspektiv

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.

Personlig_Bankman - En kvantitativ undersökning om bankers kommunikation på Twitter

Banks and their products are traditionally characterized as high involvement, informational purchases and as such there is a need to shape the market communication to be logical and catering to the need for information that customers are bound to have. With the advent of social media and web 2.0 a company can no longer opt out of the online discourse regarding their company. As social medias are characterized by being an active media, tailored to personal exchanges and opinions, the match with the high involvement approach that banks usually have to employ is not always ideal. We have examined what happens when banks use different degrees of personal message content and sender profiles on Twitter. Our findings suggest that while some strategies generate higher WOM intentions, others may provide a greater level of sender credibility..

Investeringssparkontot : För schablonbeskattning ? i tiden

Title: The Investment Savings Account ? Standard Taxation ? Right in TimeAuthors: Gustav Mårtensson and Erica Nordström LöfSupervisor: Göran HäggBackground: In order to facilitate and stimulate financial investments among privateinvestors the organization Aktiespararna made a proposal for a standard-taxed account. As aresult of this, the Swedish government decided to implement the Investment Savings Accountin January of 2012. The introduction of the Investment Savings Account implies that there arenow three different types of accounts for financial investments that are differently taxed onthe Swedish Market. Private investors can improve their after-tax results by combining AssetAllocation and Asset Location, according to earlier studies.

Samband mellan hög incidens ämnesomsättningssjukdomar och klövhälsa hos svenska mjölkkobesättningar :

Metabolic diseases in dairy cows are considered to increase the risk for claw lesions, most of all laminitis, sole haemorrhages and sole ulcers, but also to increase the risk for environmental claw lesions. The aim of this study was to compare claw health in 27 Swedish dairy farms, 18 with high incidence of metabolic diseases and 9 with low incidence. Data on claw health status was retrieved from recordings at routine claw trimmings and analysed on herd level regarding the prevalence of: any lesion, interdigital dermatitis, heel-horn erosion, sole haemorrhages, sole ulcer, lameness, abnormal claw shape, and other diseases (abscess in the white line, limb disorders, double sole, laminitic groove, white line disease, interdigital phlegmon, interdigital hyperplasia, toe abscess and verucose dermatitis). Mean prevalence of any lesion for herds with low incidence of metabolic diseases was 48 % and in herds with high incidence 41 %, and there was no statistical difference between the two groups. Mean prevalence for interdigital dermatitis was 2,0 % and 6.4 % in the low and high incidence groups, respectively (p.
