Klassifikation och definition av socialantropologi En jämförande studie ur ett hermeneutiskt perspektiv

The purpose of this thesis is to study the relationship between the definition and bibliographical classification of a certain academic subject; social anthropology. The theoretical framework consists of views held in Information Science regarding the definition and classification of subjects. The methodological onset is based on hermeneutical concepts that allow an extended analysis of abstract structures of thought. This analysis comprises of two parts; a descriptive analysis and a comparative analysis. The result of the descriptive analysis, whose aim is to describe the academic subject social anthropology, shows that this is not easy to define, instead it is nowadays almost the same as cultural anthropology.

Tredimensionell sensorscanner

This report is a bachelor thesis presented at the department of Computer Science andEngineering at Chalmers University of Technology. The aim for the project is to find a simplemethod to measure and display physical quantities in a three dimensional room.The report describes a method to construct a system for measuring differentphysical quantities via sensors. The system must be built in a modular and expandable way tobe adaptable to different tasks.The system explained in the report consists of two parts;A physical scanner with moveable probes for carrying sensors and a microcontroller forcontrolling the probes and communicating with the next part.An application written in Java for storing the measured values and presenting them in a lucidperspective.It is possible to construct the scanner with different designs and circuitry, with multiplexers andflip-flops, to ensure that an unspecified number of probes can be added to the system and thatthey can be operated simultaneously.The Java application is written in a modular way, using a design pattern that separates eachindividual part of the application. It contains exceptions and interfaces that ensure a safe andexpandable application..

Webbsystem för matprisjämförelser

This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.

Det Intelligenta Huset : - En studie i hemautomation

Today all buildings contain some form of home automation. It might be heating controlled by athermostat or motion detectors controlling outdoor lighting.This paper,The Intelligent House, deals with the planning of a house in Kiruna, in the north ofSweden and further immerses itself in home automation or intelligent control in single-familyhomes. The house has been entirely planned, from layout to structural design and plumbing.The purpose of the paper has been to investigate the possibilities in home automation in singlefamilyhomes and to choose a suitable home automation system for the house being planned.The system has been designed and the costs and energy savings have been calculated.The system chosen for the house is called KNX and is the largest system for home automation inSweden. It is used to control heating, ventilation, lighting and alarm systems in the house. Is hasbeen found that KNX is very expensive and that the amount of energy, possible to save in thehouse, using the system, is relatively small.

Förstudie kring ledningssystem vid reklambyrån Confetti

The aim of the project is to develop a tool for a management system at the advertising agency ofConfetti. The company has during a longer period of time felt a need of introducing a quality and environmentalsystem but have a lack in resources of knowledge, time and money. Their goal is to have aconcrete documentation which describes their quality policy and the function of the activity.The work has been performed by mapping and analyzing the processes of the company according tothe process model with focus on one pilot process. New routines have been developed and documentedin a management system.Confetti would like their management system to fulfil the ISO-standard so that they eventually inthe future can be certified. Therefore a literature study has been done according to management systemsand standards.

Ledarskap inom ramen för ett systemutvecklingsprojekt - fokus på en arbetsprocess med stöd i Vattenfallsmodellen

Many research reports mention the fact that a huge number of all system development projects never reach a successful ending; with other words never fulfil formulated goals. By identifying and forming success factors (and in some aspect risk factors) that the project manager in practice can use, this study may be seen as a step in the direction towards minimising the high number of failed system development projects. The purpose of this research report is to investigate how a system development project, where the development process is based on a specific development or process model (in this case the Waterfall model), can and should be driven. I aim to clarify what is demanded of a project leader for the specific development process and give an account for which eventual leadership qualities that can be well suited for given situation in relation to the need for technical competence. Among other things the project manager should inspire confidence, drive, be a decision maker, engage and own some form of basic knowledge in the field of system development.

Pedalkraft system : Stödsystem för elproduktion i småskalighet

Detta examensarbete vänder sig till personer som är intresserade att använda nya miljövänligametoderna för elproduktion eller personer som redan använder små vindkraftverk ochsolpaneler med behovet av en extra energikälla i små stugor eller avlägsna platser där tillgångentill elnät är omöjligt. Syften i detta arbete är först och främst att bygga ett system förelproduktion med hjälp av en cykel. Sedan bestämma mängden av elektrisk energi en personkan alstra med systemet. Slutligen svara om detta system skulle kunna använda som ettstödsystem för elproduktion i småskalighet.Den första målsättningen är att utforma ett system med användning av kraftelektronik där denkraften som genereras matar lasterna. Den mekaniska delen kommer att konstrueras som en delav energikällan, därefter kommer det att utformas en kontroll för att styra effekten viaelektroniska komponenter, de elektriska belastningarna matas av systemet, kommer attsimuleras.

Can increased activity recorded with help of activity monitoring sensor indicate an upcoming calving?

The purpose of this study was to find out if motion movements, e.g. number of lying bouts and lying time with a registered activity monitoring sensor can detect an impending calving and thereby be used as a measure and an indicator for an upcoming calving. For this, automatically step sensors were used and were attached to one of the cows? hind leg. The sensor registered the individual step and movement activity of the cow.

Lera för livet i lek & utforskande : en studie om pedagogers syn på estetiskt arbete i förskolan

This study intends to examine teacher´s thoughts and perception of esthetic activities at preschools. I have chosen to restrict the esthetic area to the significance and function of clay to the teachers and children. On the basis of the belief that children can, and need access to a variety of ways to express themselves, we used the interviews to take part of teachers work and thoughts concerning clay, and the esthetic work. I have in this qualitative study addressed four questions: How do the teachers use clay in preschool activities? What do the teachers think about clay as a tool in the educational work at the preschool? Are the teachers working from the perception of children?s rights to express themselves in different ways and with the help of different tools? What function does clay fill for the children?I have interviewed eight teachers and taken part of both older and more recent theories around children and the creativity in esthetic contexts.

Landscape? Urbanism : om semantik och språkets betydelse

I och med Landscape Urbanism har landskapsbegreppet sedan en tid upplevt en hausse inom arkitektur- och stadsbyggnadsdiskurs. I och med denna nya uppmärksamhet för landskapet har ett nytt behov uppstått: att diskutera vad som egentligen menas när man använder detta mångtydiga begrepp. Med detta fokus behandlar denna uppsats komplikationerna som uppstår när ordet landskap och dess ofta motstridiga betydelser används utan att kommunicera vad som avses. Med utgångspunkt i lingvistiska teorier hävdar jag därför att språket och således semantiken, ordens innebörd, är av yttersta vikt för att formulera och konstruera nya stadsbyggnadsteorier såsom Landscape Urbanism. För vad betyder egentligen Landscape inom Landscape Urbanism? Hur kommer det sig att ordet dels används för att referera till ytorna ?mellan husen?, men även används som ett begrepp som beskriver hela stadens dynamik? Hur kan dessa mycket olika tolkningar av ordet landskap existera under en och samma paroll ? Landscape Urbanism? Denna uppsats behandlar dessa olika tolkningar, men presenterar även ett sätt att hantera detta till synes alldagliga men mångfacetterade ord. Due to Landscape Urbanism the term landscape has experienced a recent hausse within architecture and urban design discourse.

Bibliotek och ungdomar med annan språklig bakgrund än svenska ? en enkätundersökning

This thesis examines what and in which language young people in Sweden with other linguistic backgrounds than Swedish read, as well as if they have access to the literature that they demand, how they use the library and what kind of role the library plays to them. The chosen method was quantitative and it consisted of a questionnaire as this method is useful in quantifying phenomena, which is the purpose of this thesis. The investigation shows that the studied population is bilingual. I hope that the thesis points out the range of the problems and that these issues need to be solved within the society and not the within the family. We need to make use of the resources of the young immigrants, as their cultural competence, in some cases even bi-cultural competence, can be useful for the Swedish society.

Uppvärmningssystem - En analys av valmöjligheter för småhus

When constructing a new house many questions appear, from architecture to decisions regarding installations. Sweden is situated in a cold part of the planet and questions regarding which heating system to install face everyone who decides to build a new house. This thesis describes a construction solution of a villa in Kiruna. The extended essay analyzes which heating system is most suitable for the construction. The options are geothermal, district and pellet heating systems.

Transtaggning och ämnesordsaktivism : Indexering i händerna på Den Andra

This thesis emanates from the understanding that it is of importance that transgender-themed literature is indexed in accordance with how people who identify as trans name themselves and interpret the concept of trans. Based on interviews with representatives from controlled vocabularies and LibraryThing users who tag transgender-themed material, existing attitudes towards user influence in controlled vocabularies are described and the significance of tagging for transgender-themed material is looked into. With queer theory and postcolonial theory as its main framework the analysis looks at what possibilities there are for users to influence controlled vocabularies and explores possible strategies for a future library catalog that includes the voice of the Other. The study lands in the understanding that many of the resisting attitudes towards user influence within the systems for subject headings in fact lie in the systems? limitations.
