Galoppträning och körning med två travare
The aim of this study was to evaluate whether gallop training, rather than regular drive training, is worthwhile for trotters race performance. Another aim of the study was to expand the author?s riding- and driving capacity, and get more practical experience on the impact of interval training on trotters. The sample population in the study was two trotters, one Standardbred, and one cold-blood. Given the small sample population, the results of the study is only indicative on the effects of gallop training on trotters, and not conclusive.
Koffeinets inverkan på prestationsförmågan vid styrketräning ? En systematisk översiktsartikel
AbstractTitle: The effect of caffeine on performance during resistance training ?A systematic overviewAuthor: Amanda Jonsson and Erica BenderSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2015-03-31Background: Products with high content of caffeine has in recent years become popular for optimizing physical performance.

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.
Diversifieringsmöjligheter och deras effekt på avkastning : en jämförande studie av etiska och traditionella fonder
Aim: Based on portfolio theory, which highlights diversification, and CSR, which describes the value of social and ethical responsibility of corporations, this study examines whether there is a difference in risk-adjusted performance between ethical and traditional mutual funds. Ethical funds are limited in their opportunities of diversification and should therefore be limited in their potential perfomance. On the other hand, a focus on social and ethical responsibility can be profitable.Method: The study uses a quantitative approach where we used 25 mutual fund in each category, ethical and conventional mutual funds. The mutual funds and their data has been obtained from www.morningstar.se and www.pensionmyndigheten.se. Historical performance between 2009-2013 were processed to obtain the Sharpe ratio and M2.
Skogsbruksplanen - ett hjälpmedel i vattenförvaltningsfrågor? : en intervjustudie
After the mandatory rules for clearing was removed in 1994, the clearing area has increased in Sweden. After the storms Gudrun and Per, the areas became planted with new plants, mainly spruce, but also other tree species. Storm areas are now being invaded by naturally rejuvenated birch in the tilling tracks. Since the birch often is initially growing faster than the spruce it is inhibiting the growth and is also damaging the spruce.
The purpose of this thesis is to study the new brush saw with chain and compare it with the conventional clearing saw, mainly in terms of performance and ergonomics. The results show that the new brush saw with chain is very good in almost all clearing operations compared to the conventional clearing saw.
Konstruktion av testrigg för moderna ångexpandrar
This report summarize what have been done during the Master of Science Thesis that Klas Schjelderup has written for the company RANOTOR Utvecklings AB. The company is developing modern steam engines and this work should develop a machine to perform tests on a new type of piston seal that hopefully could be used in the future. The steam engines will be both volumetric and energy compact, around 1600hp/literof cylinder volume, and it will have a lot of practical applications.The new type of piston seal is hydrostatic lubricated which means that a fluid is separating two faces that normally is in contact. In this case pressurized water is used to separate the piston seal from the cylinder wall. RANOTOR have earlier formulated that at least the expander in the modern steam engine have to be oil-free, due to other components functionality in the closed water system.

Lärarrollen i förändring : En intervjustudie om lärares inställning till en förändrad lärarroll
During the past twenty years, the Swedish school systems have slowly changed to becomemore and more performance-driven. Private schools have been growing in general and, likeindependent schools and schools managed by municipalities, they profile themselves. Schoolsare becoming more performance and result-oriented, which has changed the roles of teachersin a dramatic way and is in general, still changing.By profiling students based on theirindividual performance, schools are able to help students identify themselves and their owngoals. The process of profiling is a slow one in which some teachers adapt more quickly thanothers, and one that is critical for other teachers to learn in order to keep up with the demandsof society.Schools, like ordinary businesses, are in constant competition with each other to keep up withthe newest and greatest models of teaching and to rank among the best in high achievements.Perhaps the downside of this modern school structure is that it is often difficult to have aschool where both school management and teachers see eye to eye. School management must heavily focus on the school?s results as a whole.
Implementering av Patientsimulator för Anestesimaskiner
In order to facilitate testing of anesthesia machines a patient simulator has been required by Maquet Critical Care AB. A patient simulator has been developed to reduce expensive and time consuming animal experiments and temporary lab arrangements. The patient simulator has been developed and designed to simulate human lungs with regards to anesthetic uptake, production of carbon dioxide and heating and moisturizing exhaled air.The system comprises a container and a test lung to simulate the volume and the dynamic of the human lung. The simulation of uptake of anesthetics has been implemented by pumping a fraction of the gas from the container through a bypass circuit with an active charcoal filter that adsorbs volatile anesthetics. The flow through the bypass circuit is generated by a pump and is controlled by a linear valve.The resulting performance of the patient simulator has fulfilled the requirements.

Effekten av avståndsoperatorer samt expansion med synonymer med avseende på återvinningseffektiviteten
This thesis examines the effects of proximity operators and query expansion with synonyms on retrieval performance. The queries were expanded with synonyms and structured with proximity operators where the permitted distance between terms varied from 1 to 3. The expansion terms were selected from the online lexical reference system WordNet. Initial query terms were selected from 28 topics that contained compound words and were chosen on the basis of their expandibility. The English morphological analyser ENGTWOL was used for normalization of query terms.
Miljövärdeflödesanalys av Risifruttiproduktionen : En utvärdering av värdeflödesanalys och miljövärdeflödesanalys
This report is the result of a thesis work carried out on the Risifrutti production at the company Procordia Food AB. The thesis is at a master level and is the final work for the author to receive a Master of Science in Innovative production at Mälardalen University. The thesis comprises 30 credits and has lasted for 18 weeks. The thesis is mainly a research on whether it is possible to perform an Environmental Value Stream Map (E-VSM) in a food processing industry and an evaluation if the tools E-VSM and Green Performance Map (GPM) are useful in this type of industry. An extra part to this research is to use the results from the E-VSM and give Procordia Food AB information on improvement potentials in the Risifrutti production. The author has found it difficult to collect some of the quantitative data to the E-VSM, mainly regarding energy, but by using the Value Stream Mapping (VSM) tool and other Lean tools the author was able to identify and quantify several wastes in the Risifrutti production. Recommendations for improvements based on these wastes have been given to the company. In the research part of this report the utility of the Value Stream Map, Environmental Value Stream Map and Green Performance Map in a food processing industry have been analyzed. The author has found that the Value Stream Map has been a useful tool since waste and unevenness in the tact of the production has been identified. The Environmental Value Stream Map and the Green Performance Map are also great tools when a company wants to analyze their environmental impact and then invest in environmental improvements. However, no profound energy analyzes has been done in the Risifrutti production because of the lack of energy meters for steam, electricity and compressed air in the production lines..
Avståndet mellan styrande och styrda i EU
Performance Management är en process som syftar till att säkerställa att alla inom en organisation arbetar i samma riktning. Detta uppnås genom att öka tydligheten kring organisationens strategiska mål samt koppla dessa till medarbetarens individuella mål. Vidare är det viktigt att kommunicera vad som förväntas av medarbetarna i termer av arbetsprestationer samt hur detta skall uppnås för att lyckas med uppdraget att minska gapet mellan medarbetares arbetsprestationer och ledningens ambitioner (Armstrong & Baron, 2005).Uppsatsens övergripande syfte är att undersöka vilka erfarenheter ledare inom det multinationella telekom- och IT-företaget Logica har av att arbeta med Performance Management samt vilka delar av implementeringen som har varit lätta respektive svåra att genomföra. Vidare vill jag undersöka hur organisationen ytterligare kan förstärka arbetet med Performance Management-processen baserat på ovanstående.Den empiriska undersökningen har genomförts med kvalitativ metod i form av tre stycken fokusgruppintervjuer med ansatsen Experiential Focus Group. Som komplement till fokusgruppintervjuerna har analys av interna dokument som beskriver Performance Management-processen inom Logica, genomförts.Resultatet av undersökningen visar att ledarnas upplevelser av Performance Management-processen varierar beroende på vilken typ av arbetsgrupp man är ledare för.
