Hjärtfrekvens och hjärtfrekvensvariabilitet som fysiologiskt mått på mental stress hos hästar
SAMMANFATTNING
Denna litteraturstudie syftar till att utvärdera hjärtfrekvens och hjärtfrekvensvariabilitet som fysiologiska mått på mental stress hos häst. För att utvärdera detta har olika artiklar studerats. Artiklarna redovisar studier där hästar utsätts för framför allt mentala stressmoment. Under stressmomenten har antingen hjärtfrekvens (HR) eller hjärtfrekvens och hjärtfrekvensvariabilitet (HRV) registrerats. Hjärtfrekvensvariabiliteten kan omvandlas till ett antal parametrar, bland annat lågfrekvensband (LF) och högfrekvensband (HF).
"Ettan" som kom först : En kvantitativ innehållsanalys av hur en studenttidnings förstasida förändrats genom tiderna
The aim was to explore how the first page of a student newspaper has been changed over time since it was founded in the 1960´s.This thesis explores how the front page of the student newspaper Lösnummer has been changed since it was founded in 1966. It concerns the location and frequency of elements and it is based on theories of layout, the first page and visual communicationIn addition, the thesis develops a new kind of method for determining the location of elements on the type area. The method is based on the hexadecimal number system. It is formed as a grid which is placed on the first page to determine the location of the elements.It concludes that the frequency of elements had its peak during the 1970´s and has ever since decreased gradually. Image placement has gone from being scattered all over the front page to be centered and increase in size. .
Utvärdering av prototypen för ett kollaboratorium inom biblioteks- och informationsvetenskap
This study is a formative evaluation of a prototypecollaboratory for sharing data collection instruments inlibrary and information science (LIS). The aims were to findout: how the study participants, five hospital librarians,experienced the interaction with the prototype while workingwith predetermined tasks; and their views on the differentfunctions of the prototype collaboratory.Methods used for data collection was as a survey; followedby a think-aloud session where the participant verbalisedhis/her thoughts during the interaction with the prototype;and finally a semistructured interview. The survey wasanalysed with a Frequency distribution, while the data fromthe other methods were analysed qualitatively by extractingthemes from the transcribed sessions.The results show that although the librarians expresseddifferent problems while working with the interface, mainlyrelated to the language in the prototype collaboratory anddifficulties with the page for applying metadata, all of themwere confident in being able to learn the system after using itfor a while. The librarians had a positive attitude towardssharing data collection instruments as well as comments inthe prototype collaboratory. At the same time, they wereaware that students and researchers might have differentabilities or incentives to work and share information.
Modeller vid Portföljutvärdering: En fråga om fördelning
Syftet med denna uppsats är att med hjälp av exempel och illustrationer förklara och klargöra tillvägagångssättet för Amin och Kat?s version av Dybvig?s Pay-off Distribution Pricing Model samt Keating och Schadwick?s Omegafunktion. Vidare ämnas Pay-off Distribution Pricing Model, Omegafunktionen, Sharpekvoten, Jensen?s Alpha och Treynor-index beräknas på icke-normalfördelade distributioner i form av avkastningar på hedgefonder samt normalfördelade avkastnings-distributioner på aktiefonder. Resultaten från dessa beräkningar kommer att rankas och jämföras främst genom att söka observera likheter och olikheter.
Bulleremissioner från vertikalaxlade vindkraftverk
Wind power in Sweden is expanding in response to the government's decision that 49% of Sweden's power should originate from renewable energy sources by the year 2020. Problems with noise and sound emissions related to wind turbines are a constant argument against the wind power expansion and this paper means to examine if vertical axis wind turbines might be a viable alternative to the conventional horizontal design for noise sensitive areas. In order to determine factors like difference in frequency, noise propagation and noise emission level, measurements of both horizontal and vertical axis wind turbines have been completed and the data analyzed with MATLAB. It is shown that there is a difference in how the noise from the two types of turbines propagates due to avariation in the frequency spectra of the emitted sound. It is also shown that vertical axis wind turbines generate a lower sound emission with less intensity inthe lower frequencies..
Sjukdomsfrekvens och utslagningsorsaker hos kor med 12 respektive 15 månaders kalvningsintervall
The incidence of many of the most common diseases in dairy cattle has been proven to be highest during the time closest to calving. It is possible that the current breeding strategy with 12 month calving intervals increases the risk for disease in dairy cattle, which is problematic concerning both animal welfare and for economic reasons. The economic incentives behind a calving interval of 12 to 13 months have mainly been based on milk- and feed- costs and no costs due to diseases or fertility disturbances have been included.The aim of this study was to see if a lengthening of the calving interval would result in lower disease frequency. The hypothesis is that cows with a planned calving interval of 15 months have a lower disease incidence than cows with a calving interval of 12 months due to less number of calvings. Therefore the difference in disease frequency should be larger when compared over a long period of time, such as over lifetime, since cows with a longer calving interval experience fewer calvings.The study was performed between August 17th, 1994, and January 24th, 2007.
Är Grönt Skönt?: En studie om hur effekten av grön marknadsföring påverkas av förekomsten av miljöargument inom produktkategorin
Al Gore may have helped put global warming on the agenda. However, it is not a new subject. Neither is so called green marketing a new phenomenon within branding and communication. As more and more companies establish environmental strategies there exist beliefs that the environmental focus is becoming a triviality, which is the reason for this study. Implementation of words such as ?environmentally friendly?, ?green? and ?global warming? is becoming more and more widespread and frequently used within marketing communication.
Rum för musik på biblioteket: En fallstudie av Bibliotek 10 i Helsingfors
The aim of this master's thesis is to study how the design of the music library space affects how it is used and its role as an arena for culture. This is done in form of a case study of Library 10 in Helsinki, a public library branch that specializes in music and information technology. The backdrop to the study is the changing context for cultural activity in the information society and the role of public libraries as public space and meeting place. By analyzing the distribution of space in the library, the distribution of functions and artefacts and the spatial use of the room, I interpret the ways in which this distributional logic produces a unique place for music and culture. I discuss the music library design in a space and place perspective, utilizing theoretical tools from cultural geography and the space theories of Henri Lefebvre.
Distribution av digitaliserad information : en studie av musikmarknaden
Bakgrund: Från att ha förmedlats via grottmålningar, papperstidningar, böcker och skivor har distributionen av contentprodukter blivit smidigare i och med att internet har fått genomslagskraft. Denna typ av distribution är mycket snabbare och dessutom i många fall billigare än de tidigare typerna. Dessutom finns det numer möjligheter för gemene man att publicera och distribuera content. Syfte: Att undersöka hur contentdistribution i musikindustrin förändras på grund av den pågående övergången från analog till digital ljudförmedling. Dessutom undersöka vad det finns för incitament till fortsatta förändringar i framtiden.
Internetbaserade insamling och behandling av data
AbstractAim of this project was to analyse signals and try to localize the position of source of sound. It is donewith three microphones which have 90 degrees angle to each other. Each microphone detects one partof the sound wave. The microphones are connected toan ADC which turns signals from analogue todigital shape. After that the three signals are transformed to a computer.

Aktiekursförändringar och sökfrekvens på internet
The purpose of this Bachelor thesis is to analyze if there is a correlation between stock prices and the amount of searches of the companies names on Google. The theories used in the study were Capital Asset Pricing Model (CAPM) and Efficient Market Hypothesis (EMH). Regressions analysis is used as the statistical method to see if there is a significant correlation between the stock prices and the amout of searches of the company name on Google. The data used were the rate of return of three companies (ABB, Oriflame and Sandvik) on the Nasdaq OMX Nordic stock market, the rate of return of the Nasdaq OMX Nordic stock market index (OMX Stockholm_PI) and the Google search frequency from Google Trends on each company. The result showed no significance and the conclusion of the thesis is that there is no significant correlation between the three studied companies and their search frequency on the search engine Google..
Mätsystem för effektförluster i en högfrekvenstransformator
To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.
Byggnadsminnesförklaring : ett långsiktig hållbart skydd?
There are currently 2160 buildings in Sweden that are protected by law with the designation as a cultural heritage building, which is the strongest protection that can be obtained for a building of cultural historic significance. The purpose of this thesis is to research how strong and sustainable the protection of such a designation is and how you can motivate a revocation. Furthermore, this thesis aims to give an overall insight into all cases where there has been a revocation.To achieve the protection of a designation as a cultural heritage building, the object has to be of outstanding interest on account of its cultural historic value. In the first part, this thesis gives a short historic background of the cultural heritage law and its terms, like outstanding interest and cultural historic value. The County Administrative Board's documents about revocation are the main source for this research.There have been 24 cases of revocation and the frequency of such cases has increased in the past ten years.
Gränsöverskridande handel ur importörens perspektiv
Research in international trade situations has mainly focused on understanding the exporter?s actions and has showed ways on how these can be optimized. Although the importer in most cases, until this day, has been left outside this focus, it has been showed that the importer often is the active participant in an international dyad. It is the importer who is actively seeking suppliers for its production or distribution. Based on previous research in the area, the following study identifies the factors that are vital to the importer for satisfactory relations.
