En utvärdering av två pearl growing-metoder i ISI Web of Science

The purpose of this thesis is to evaluate two pearl growing methods in ISI Web of Science. The methods tested are Find Related Records FRR, an automatic service that uses bibliographic coupling, and Author Keywords AK, where searches are performed using the two first keywords from this field. Both search methods were used on twenty initial documents and the first twenty hits were evaluated for relevance using a binary scale 0,1. The relevance criteria were based on specific information needs connected to every initial document. The measures used to evaluate the effectiveness of the search methods were Precision at DCV=10, P10, and Uninterpolated Average Precision AP.

Modulär Mekanikstruktur för Nanosatelliter

The objective of this thesis was to present a design proposal on a modular mechanicalstructure for a nanosatellite. The size of the structure should follow the CubeSatstandards. This standard divides satellites in units (U), where 1U is equivalent to acube where sides measure 100 mm. 2U corresponds to the same volume and size as2 assembled 1U structures, and so on. The focus was to develop a structure in theorder of 3U and 6U.At the integration in the satellite launch rocket, there are a couple of differentinterfaces, where the structure is adapted to common ones; P-POD and CSD.

Kvalitet i brödvete :

The quality of bread wheat is a large subject to study. The quality rests on two legs. The first one is the inheritance of specific characters, which can be influenced through plant breeding and type of cultivar. The other one is the environmental influences, such as crop rotation, nutrition, harvest and storage. The latter factors are possibly to affect through cultivation practices, while other factors are not possible to influence on for the grower, such as seasonal changes of weather and the soil content.

Risk för spridning av ogräsfrö med rötrester : en litteraturstudie

With an increasing production of biogas follows an increased amount of digestate. This could potentially be a valuable source of fertiliser with the destruction of weed seeds as a possible advantage. However, there have been some concerns regarding the product still containing viable seeds of weed. In this Bsc thesis the results of previous research on the fate of weed seeds in biogas production is summarized. It is also a comparison of research on the effect of similar processes such as silage, compost or animal passage on seeds. The purpose of this is to evaluate risks of spreading viable seeds, potentially problematic species and perhaps to find out how to eliminate the risks. The literature review revealed that previous research mainly indicates low risks regarding many of the tested weed species, but not all studies show the same result, therefore extended research on the subject is desirable.

En flygande fallstudie : -om SAS använder information från sina kunder vid tjänsteutveckling

Customer information is to be seen as an essential part in service development. The company should be aware of how their customers experience their services. The company can get access to customer information through complaints from their customers. All information obtained from the customers is not possible to use when developing new and existing services. The information has to be analysed before it is possible to use it for service development.This paper describes if Scandinavian Airlines (SAS) uses their customers as a source of knowledge when developing new and existing services and in that case how.

Kommunala roller i megaprojekt - Lunds kommuns hantering av ESS-projektet

The aim of this thesis is to investigate how municipalities handle planning of megaprojects. The term megaproject here refers to a large project in terms of time, space, investments, numbers of agents etc. With an increasing importance of the phenomena the need of discussing the role local politics could take in this process is important.How do municipalities handle the difficulties that come with megaprojects and what roles do they take in their work with megaprojects? These empirical questions are tested on a case where the municipality of Lund works with the megaproject European Spallation Source (ESS). A theoretical question discusses the megaproject in the light of governance and government, and structures the analysis around these two important terms.Different parts of the municipality handle there part of the planning from there own logic.

Kravanalytikerns roll : Kommunikationsförmedlare mellan olika intressenter i ett IT-projekt

According to statistics, requirements management is identified as a major source of error to failed IT-projects. Moreover communication is identified as a factor affecting the require-ments management and can lead to deficiencies in the requirements. The requirements analyst is responsible for managing the requirements from the different stakeholders, act as a com-munication accommodator and to translate abstract requirements expressed by users to more specific requirements that developers can implement. The purpose of this thesis is to study the role of the requirements analyst to investigate the problems that may arise in working with requirements management.  To achieve the purpose we have performed a requirements management process in which we ourselves took the role as the requirements analysts. The requirements management process consisted of three phases: gather requirements, document requirements and validate require-ments.

Småhusutformning och solenergiutnyttjande

This paper goes through solar energy and what uses it has. It is also a guide in the choice of solar collectors forthe real estate that I have drawn for the thesis work.Solar energy is a renewable source of energy from the Sun's light. Energy can be used to produce both heat andelectricity through solar collectors and solar cells. Some of the benefits of solar energy is that it is completely freeto extract, environmentally friendly and virtually maintenance-free. Disadvantages are that the technology isexpensive, does not cover the entire energy needs and takes a long time until it pays.

En studie av evalueringar av webbaserade söktjänsters återvinningseffektivitet

The aim of this thesis is to describe and critically investigate eight different evaluations of the retrieval effectiveness of webbased search engines. The questions to be answered in this investigation are: - What kind of relevance judgements have been used? - Which criteria have been used when judging the relevance of a document? - Which measures have been used? - How many queries have been used? - How were the queries constructed? - What document cut-off value has been used? - Has hypothes testing been applied? - What kind of webbased search engines have been included in the evaluations? The study showed that although the evaluations investigate the same phenomena, they are very different from each other in certain aspects. Generally the study showed that precision is the preferred measure in comparison to recall in the chosen evaluation even though all the included evaluations have constructed unique formulas for calculating precision. Some attempts to measure relative recall have been performed but they all suffer from different defects.

Bloggarens val: En studie av lästips på bloggar

The aim of this master thesis is to examine readers? advice in weblogs - frequently modified web pages with a series of archived entries. We have chosen to study a specific kind of entry that contains information about a book of fiction- not for children and young adults - and the bloggers? comments regarding that same book. The entries are published in ten weblogs that all deal with literature and reading.

Fair Trade - en studie över socialt ansvarstagande investeringar i terminer

This study investigates how the concept of Social Responsible Investment (SRI) can be applied to futures trading. More specifically, this study examines the possibility of creating a SRI-product for an investor, active in futures investments within commodities, energies and stock indices, and the content of such a product is suggested. We conducted a qualitative study, based on a number of interviews. The study suggests that investments in futures of specific assets are to be equated with investments directly in the underlying assets from a SRI point of view. Therefore, we analyzed the underlying assets of futures traded commodities, energies and stock indices, and used social screening, together with specific screening criteria, for the analysis.

Äldres upplevelser av palliativ vård och omsorg : - en kunskapsöversikt

Elderly patients experiences of palliative care ? a rewireThe purpose of this paper was to study elderly patient?s experience of palliative care with present knowledge as starting point. The questions were; what criteria do the elderly, dying person think is most important to fulfill in palliative care? and how satisfied is the elderly, dying person with the palliative care that are giving to him/her? The information were collected by a data based search trough science magazines and technical literature. Four relevant studies were found; Costello (2001), Heyland (2005), Wilson (1999) and Formiga (2004).

Kvalitetsledningssystem enligt ISO 9001 : Produktionsprocessen

This report is the result of a thesis work done at the Department of Engineering Sciences, Uppsala University, and includes 15 ECTS points. The work has been performed at Företag A, a company specializing in electronics whose major product has become a sophisticated tool used by authorities across northern Europe. Företag A has initiated a quality management system according to the criteria set by ISO 9001. Following demands from customers, Company A has now decided to also start working towards a certification according to SS-EN ISO 9001:2008, this work is the foundation for the thesis work. The thesis work has been limited to the production process and the aim has been to enable this process to be certified according to ISO 9001:2008. The work has been performed by analyzing the existing quality management system and the requirements for each process included, whereby the gap between the current and the target state has been mapped. Suggestions have then been made on how this gap can be filled, some of these suggestions have also been carried out during the thesis work. The conclusions drawn are that quality management does not have to be complicated, but quickly becomes so when the complexity of the processes increases.

Småskalig säsongslagring av solenergi för uppvärmning av bostäder : Simulering av lagerutformning och konsekvensen av adderade uppvärmningsbehov motsvarande en pool och ett atrium

The sun is a huge energy source with great potential of providing energy to the heating of homes and other buildings in an environmentally sustainable manner. In order to provide buildings with energy from the sun it is necessary to transfer the energy supply over time to when the demand arises. By storing the heat in a seasonal storage, solar energy from the summer can be used in the winter when the demand for heating is greatest.Today's existing plants are mainly in Europe and particularly in Germany. These facilities are designed to supply heat demands greater than 400 MWh and covers about 40-50 % of this need which consists of energy for space heating and domestic hot water. How much of the heat demand that is covered, the solar fraction, is partly due to losses from the storage which in turn is connected to the surface area of the storage.
