Smarta Hus: Nya behov och lösningar med participativ design
In this Bachelor Thesis (20 p.), we present the history and development of
"Intelligent Houses", and most important- explore some of the future
possibilities in this area.
The project has been carried out through an interdisciplinary cooperation
between three different educations at the Blekinge Institute of Technology.
By conducting a dialogue with various actors with different professions, we
have been trying to identify needs within the concept of "Intelligent Houses",
were the end user is not only the tenant or homeowner.
Through Participatory Design methods, such as a Future Workshop, we have
brought the users together to discuss their own and each others needs and
hindrances in their respective work practice, and how intelligent house
technology could improve their work conditions.
We have also been testing a highly sophisticated
CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally
developed for regulating indoor climate systems.
Based on the needs we have found in our fieldwork, we have been looking at
possibilities to make multi user solutions with the sensor..
Vad är ?rätt? gjutkvalitet? Hur uppnås det?
Ever since ABB has begun diecasting their rotors instead of permanent mold casting it,variation in the quality of the cast has arisen. Diecasting is performed in three differentmachines, M1, M2, M3 with 400, 660 respectively 800 tons of die locking pressures.The aim of this thesis is to answer the following questions:What is the ?right? cast quality? How is the right quality achieved?For sizes 160-180 solutions will be proposed that consider eccentricity between thelaminate and the short circuit ring as well as elimination of the thin Al film that appearson the outer periphery of the rotors.Through considering the statistic material the most often diverging rotor type has beenidentified and one of the actual rotors has been sent to a laboratory to be analyzed inorder to establish the current defects. The result of the analysis shows that there areplenty of gas- and oxide-porosity.It has been proved that every time the dies temperature decreased below 120°C thecontent of gas porosity increased. It is due to rapid solidification of metal that flowsthrough the ?cold? laminate.It has confirmed that enhanced porosity in squirrel cage causes high impedance in therotors.
Musik som kommunikation
Music affects us humans. Marketing has long made use of music as a means to enable customers to identify with a brand, and thus increase sales. The Influence of music is obvious, but can you use this on students, and how effective is it to use in a classroom?I will answer the question: how does soft music provide reassurance/create a harmoniums learning environment at the beginning of a lesson?By observing how students react and behave to the playing of soft music. My aim is to create different strategies that teachers can effectively use to get students to ?jump in? to their lessons without wasting 5-15 minutes of class time.Professor Lennart Grosin conducts research into what is in Sweden called PESKO.
Hållbar utveckling och CSR inom foderindustrin för hund och katt : Med fokus på det ekologiska perspektivet
Pets like dogs and cats have a considerable importance for humans and research demonstrate a variety of positive economic and social effects in society due to our pet companions. The presences of pets are increasing on a global scale with correlation to economic development in low- and middle income countries. For example dogs have doubled in India over a five year period. The feed industry for dogs and cats is also the fastest growing sector in the food industry and certain pets have a significant animal protein intake which, depending on the choice of resources may provide a high ecological footprint. Examples of environmental effects with distribution and manufacturing of pet food are increased greenhouse gas emissions, waste, use of water and energy.
Bioenergi från röjningsgallringar : en jämförande studie av fyra flödeskedjor från avlägg till förbrukare
When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.

Pellets - en framtidsmarknad?
With higher prices for oil and increased focus on fossil fuels impact on the environment the heating sector are searching for alternative fuels. Pellets are a quite new product whose production has risen exponential in recent years. Today there are small-, medium-and large-scale users, where the large-scale consumers are the heating sector. The heating sector is mainly using oil to cover the increased demand during cold periods.
The purpose of this study is to analyze the potential of pellets if it would replace thermal power plants oil and coal. The study will also analyze the economic impact a conversion would mean for a heating plant and if the pellet is a reasonable substitute.
2008 statistics from the Swedish district heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil.
Ä lskade Patient - En studie av Public Service Motivations roll för motivationen hos vårdanställda
A tough working climate and the lack of extrinsic motivation at workplaces within health care raise the question of what instead drives employees within this industry. A possible answer to this is Public Service Motivation (PSM) - a type of motivation that is based on the desire to do good for society and its individuals. In order to investigate this further we have performed a qualitative study consisting of ten interviews with people working with institutional care, where the purpose has been to identify the sources of motivation and determine the impact of PSM. The results show that the compassion dimension of PSM appears to be one of the most salient motivational factors. While the rest of the PSM dimensions fail to explain the level of motivation to the same extent as compassion, other factors are recognized, such as relatedness and aspects of the nature of the work itself.
Profileringsarbete för jämställdhet inom IT-organisationer
During our formative years, technology has always had a natural part of everyday life, and for us technology has never been particularly gendered. If this depends on the climate and the attitude of our homes, ourselves, the combination of both or something completely different is a question we have asked ourselves at times. But our approach to technology does not seem as obvious to all women, and today the IT industry is heavily dominated by men. This has meant that we have asked the question whether there is any underlying reason why so few women opt for IT courses? Is there a link between how different IT organizations profiles and the prevailing gender ratio? The purpose of this study is to investigate whether there is any connections between how IT organizations are related to gender issues and how the structures, attitudes and gender actually looks like in the IT industry today, and how this can be seen in their branding efforts.
Ökad kollagring i boreal skog : Kan blädningsbrukad skog lagra mer kol än trakthyggesbrukad skog?
This study was conducted to test the hypotheses that a forest managed by selective cutting can store more carbon than a forest managed by clearcutting. The study was carried out as a meta-analysis. The data that was found was analyzed by performing t-tests on the proportional effect that the two silvicultural methods had on the driving factors of CO2-efflux and carbon stores in coniferous boreal forest. In all areas tested, an effect in favor of selective cutting was found, but not all of them significant however. The soil respiration following selective cutting was significantly lower than that of clearcutting, and the primary production of a clearcut area cannot according to reason exceed that of an area post-selective cutting.
Möte i månsken : ett belysningsförslag för Fyristorg
The object of the thesis is to propose a new lighting plan
for the square Fyristorg in Uppsala, and to describe the
process which have led to it.
It all started when I choosed the place together with the
municipality of Uppsala.
I have been doing research and analyzed how the place
and it´s existing lighting works both during different times
of the day and also in the evening.
After researching the place and it´s existing lighting I´ve
decided to put up the following goals fot the new lighting
design.
1. The general light level of the place shall be experienced
as higher than today.
2. The light level of the place shall be adapted to the light
levels of surrounding places.
3. The lighting shall be free from glare.
4. The lighting shall be adapted to people passing by.
5.The lighting shall be adapted to the surrounding
architecture.
6.
Utformning av förslag till privatträdgård på Stavstensudde :
In the west part of Trelleborg, on previous farmland a new society is under construction. It is situated right next to the ocean and close to the European freeway. Eight types of villages, all with different kind of architecture will be built in the area, one of them is Torns Village built by Skanska and Ikea. A concept called BoKlok.
This specific village consists of twelve houses and five apartment buildings. They are all somewhat classical in their appearance with wooden panel, but at the same time they have a modern touch.
Organisationskultur och kommunikation vid en fusion av myndigheter
Denna studie ämnade ta reda på hur organisationskulturen påverkades och hur kommunikationen förmedlades vid en fusion av fem myndigheter till en övergripande myndighet. Tillvägagångssättet var kvalitativt med semistrukturerade intervjuer som datainsamlingsmetod. Sexton mellanchefer från fem olika avdelningar intervjuades om hur de uppfattade sammanslagningen och hur de upplevde kommunikationen inför, under och efter denna fusion samt hur de upplevde att organisationskulturen hade påverkats. Vidare undersöktes huruvida de upplevt att regeringens mål och vision för fusionen framgått tydligt. Analysprocessen genomfördes genom att meningskoncentrera transkriberingarna från intervjuerna och dela in dessa i huvudteman med subkategorier i två matriser och sedan analysera och sammanfatta dessa under respektive huvudtema.
Har analytikernas roll på aktiemarknaden blivit mindre relevant: En studie av analytikernas påverkan på aktiers avkastning
The purpose of this thesis is to investigate if the stock market reacts differently to accounting information, depending on the stock market climate. The study focuses solely on stocks listed on the OMX Stockholm 30 during each year from 2005 to 2009. By applying the concept of Earnings Response Coefficient we can estimate how the market reacts to accounting information. The dependent variable in the equation is the market reaction on unexpected earnings, in the study described as the abnormal return on stock. For quality purposes we measure this on a ±1,5,10 and 20 days basis.
Omklädningsrummens psykiska och fysiska miljö : Niondeklassares upplevelser av miljön, trygghet och kränkningar i omklädningsrummen
Several studies has identified the locker room experience as a potential deterrent for participation in physical education. Both psychological and physical issues arise due to several factors. Psychological issues include different kinds of verbal and physical violations, comparisons between pupils, feeling of vulnerability along with a stressful schedule. The physical environment can contribute to negative experience for pupils in terms of filthy premises and cold showers. These factors may contribute to higher absentee rates in physical education.
