Att tänka om angående personligt riktad reklam i en kluttrig miljö
Previous research does not show a clear picture of the perception of personalized advertising as studies give different results - there are both positive and negative aspects. The purpose of this study is to improve the knowledge and understanding of the impact of personalized advertising in the new Internet era. The aim is to answer whether personalized advertising has more positive than negative effects on Facebook or if marketers today should rethink regarding this issue. An experiment with three advertisements was defined where one ad was with no personal targeted content and the other two included personally targeted content. These ads were analysed with the theories word of mouth, information overload and psychological ownership to see if interesting results could be found regarding ad attitude, click intention and purchase intention as well as to investigate if the attitude to Facebook could have an impact on the results.
Vilka attityder unga män och kvinnor på gym har till dopning och kosttillskott : En enkätundersökning i Gästrikland
The aim of this study was to investigate which attitudes young men and women at gym have to doping and supplements in Gästrikland. Method: This study is based on a cross sectional study design where a quantitative approach was used by 60 questionnaires which were distributed at different gyms in Gästrikland. Result: It was found that the majority had a relative negative attitude to doping, those who used supplements had a slightly more positive attitude to some of the statements compared with those who did not use supplements. Overall, the results showed a positive attitude to supplements. Compared with previous studies, it was found in the study that a smaller proportion didn?t agree that it is up to each one to use doping substances.
Sensorfusion för undervattensrobot i kärnteknisk miljö med Kalman filtrering
WesDyne TRC AB is a fully owned subsidiary of the global WestinghouseElectric Corporation. WesDyne is a world leader in non-invasive methods for theinspection of nuclear power plants. One of the inspection platforms used to scanfor defects in and around the welds in the reactor vessel is called the T-crawler.The T-crawler operates under water in a radioactive environment by stepping onthe vessel (reactor tank) inner wall using suction cups. The environment is harshand many traditional positioning sensors are not suitable for implementation. Thisthesis investigates the possibility to use a gyroscope and a pressure sensor tocreate an alternative and independent positioning system.
Naturljud inomhus - En pilotstudie i tre fall
It's an everyday experience shared by many that nature can be of help in relieving pain, reducing stress, support mental recovery etc. In the last three decades or so this experience has also found support in a large number of scientific investigations. Among other things the experience of nature has been shown to reduce stress and pain in patients and to boost concentration and reduce impulsive behavior in children. Most of this research however has mainly been concerned with the visual modality. In this thesis the aim has been to focus on the auditory modality in this context by trying to reveal some effects on people from the exposure of nature sounds played indoors in three different environments: a grammar school class room, a kindergarten play room and a post-surgery wake up room at an intensive care unit.
Användandet av samlingsprover för att bestämma besättningsstatus för smitta med Dictyocaulus viviparus hos förstagångsbetande nötkreatur :
Infection with the bovine lungworm - Dictyocaulus viviparus - is occasionally a problem in Swedish cattle herds. The infection could act in synergism with other infections such as Corona virus to create a poorer welfare and productivity in cattle. Studies have shown that a diagnosis can be made with both the Baermann method and with an ELISA. In Norway diagnosis of BVDV on a herd level is attained through pooled serum samples. The question was raised whether pooled serum samples could be used in a similar fashion to attain status on a herd level for lungworm.
EU:s klimatpolitik - förhandlingsvägen till framgång
Eleven years after broking the Kyoto-protocol, the European Union still stands in the front line, combating climate change. How come the EU, with 27 diversified states, is able to integrate its members to what is widely considered the most progressive climate policy in the world? This thesis takes a closer look at the negotiations that have shaped EU climate policy. Using negotiation-models to categorize different aspects of EU climatenegotiations, several key-findings are presented. The thesis concludes that while EU entered the Kyoto-protocol with little to lose because of external factors like previous energy-reforms in key member countries, it had plenty to win in global influence and the satisfaction of an overwhelmingly Kyoto-positive public.
Energiutredning av kvarteret Masten
I detta arbeta har en energiutredning av fastigheten Kvarteret Masten gjorts. Kvarteret Masten ligger på Nygatan 43 och Centralgatan 9 i Gävle. Fastigheten består av 30 hyreslägenheter och 3 butiker. En energiutredning innebär att energianvändningen delas upp i två delar, en tillförd och en bortförd. I den tillförda energin ingår den köpta energin i form av fjärrvärme samt gratisenergin som kommer från personer, solen, belysning och elektrisk utrustning. Bortförda energin består av transmissioner, ventilation, tappvarmvatten samt en ofrivilig ventilation. Transmissioner är förluster genom byggnadens konstruktionsdelar som väggar, tak, golv, fönster och dörrar.
Hokus Fokus - gestaltning och utformning av rum för barn i sjukhusmiljö
In this project I have worked with creating a new kind of room in a hospital enviroment for children. The main purpose of the project has been to form a secure and positive experience for the patient while visiting a specific room at the department of childrens physiologi, at Drottning Silvias Children- and youth hospital in Gothenburg.The project was based on questions like how it is possible to move the focus from the unsecure and scary, to something secure and positive, when the patient is going through an testing situation.The target gruop included a wide age span (0-16 years old), therefore I have worked with a theme, H2O, that works for diffrent ages. In the room, I have applicated the theme in different levels that is changeable depending on the age of the patient.During the project I have presented my ideas for the staff at the hospital. We have discussed their problems, what they wish in their working enviroment and how they experience the situation for the patients. I have also asked the patients how they experience the specific room today.The result of the project is a visual idea of how you can create a room, that you don?t exepect to find in a hospital..
Småskalig elproduktion i Arvika
Arvika Fjärrvärme AB, a district heating company from Arvika, today cover 74 % of their total energy production with biofuel wich runs a 16 MW bioler giving process water at saturated liquid state.In recent years Vaporel AB has introduced a new tecnique that gives an external generation of steam after boilers. The concept is built on an adiabatic pressure drop of the saturated liquid in a so called Flashbox which makes a small part of the liquid to evaporate. The generated steam is lead into a turbine where electricity is in a conventional manner.The purpose with this rapport was to do a basic study for the specific system at Arvika where it?s possible to see the potential production of electricity that follows an installation of a flasbox.The final goal was to introduce an economic analysis of a flashox installation at given conditions.To reach our goals we have created a model in Excel where we used the given conditions at Arvika Fjärrvärme to do our calculations. The model has been tested at three different states, of process water returning to potboiler, to be able to decide the optimal operation for the system at present.The studies have resulted in a pressure of the processwater at 14,5 bar (at) and a pressuredrop to 9,5 bar (at) in the flashbox.
Simulering av inomhusklimat i lågenergihus
Värmeförbrukningen för småhus minskar varje år genom att hus med allt tätare och bättre klimatskal byggs. Vid en lägre värmeförbrukning är frågan om de traditionella metoderna för värme och ventilation är ett bra alternativ för att upprätthålla ett bra inomhusklimat eller kan nya effektivare metoder erhålla ett liknande inomhusklimat med mindre investeringskostnader.Detta examensarbete är en förstudie där inomhus klimatet studerats genom datorbaserade flödessimuleringar. I studien har en modell för att på ett enkelt sätt använda CFD simuleringar (datorstödda flödessimuleringar) för att studera inomhusklimatet genom att en modell har byggs upp i tre steg för att erhålla stabila resultat av ett lågenergihus framtaget av Glommershus med avseende på konvergens krav och turbulensmodell.Studier på olika lösningar för distribution av värme har undersökts genom att resultat från modeller med radiatorer, golvvärme samt en luftvärmepump för tre olika fall på utomhus temperatur. Resultatet betraktas med hänsyn till boverkets regler för nybyggnationer av småhus.I resultatet framkom att bygga upp modellen i tresteg är att föredra vid CFD-simuleringar för ett lågenergihus genom att en rad tidsbesparande detaljer görs. Även att CFD som simulerings verktyg kan användas för att utvärdera olika lösningar för värme och ventilation på ett smidigt sätt.Vid radiatorer och golvvärme visar resultatet på att temperatur gradienterna horisontellt varierar mycket lite.
Bio min bio: En fördjupning kring kunders reaktioner till ett erbjudande ur ett upplevelseperspektiv
In the end of the 20th century, there was an increased interest in creating customer experiences, especially in the service sector. At the same time, the number of visits to the Swedish cinemas is decreasing due to new distribution channels on the market. This study aims to deepen the knowledge of customer reactions towards offerings with an experience approach, by studying similar reactions in cinema visitors. Furthermore, the study examines the contagiousness of the emotions elicited by the experience. The study approaches the problem by using a quantitative method by conducting a survey of cinema visitors.
Predation som selektiv kraft bakom differentiering av populationer av sötvattensgråsugga, Asellus aquaticus
Predation is a strong dective force on invertebrate prey. Asellus aquaticus differs in pigmentation reed and submerged vegetation habitats in lakes. Light pigmented individuals al vegetation dominated by Chara sp. while dark pigmented individuals dominate in the reeds. These differences have been hypothesized to result from background matching.

Konstens roll i rummet - Om konstens inverkan på uppfattningen av en arbetsmiljö
The concept of art infusion has become more and more used in the field of marketing and product advertising, and the phenomenon has been subject to research. The purpose of this paper is to study how the perception of an office environment is influenced by different kinds of art settings. The study is made as a survey in which the respondents have been exposed to working environments, only differentiated by the existence of different kinds of art or non-existence of art in the presentation. There are many conclusions to draw from the study, the most important is that the presence of art gives positive spillover effects on the surrounding environment..
Tvåspråkiga pedagoger i flerspråkig miljö : En- och tvåspråkiga perspektiv på tvåspråkiga pedagogers roll i den mångkulturella förskolan
The purpose of the study is to investigate into professional knowledge of the bilingual teachers, compared to monolingual, and what benefits they give to pre-school. Qualitative method was used to get an understanding of informant´s perspective on bilingual teachers. The informants believe that bilingual teachers are able to understand all the children. A bilingual teacher can make the children feel secure. If one has a positive attitude toward bilingualism, the bilingual children also show a positive attitude that in turn contributes to learning and development of the language..
