With the technological development of the last decades, an increasing number of genealogists are carrying out their research online. The purpose of this master?s thesis is to examine how and why genealogists' information behavior has been influenced by the use of online services for genealogy. Using a conceptual model of genealogists' information behavior as theoretical basis for the study, I examine how the use of online services affect genealogists? search process, what information they are looking for and what information resources they use.

This essay explores to what extent the Swedish language version of Google Images meets the usability requirements of average everyday users. Previously published studies on user behaviour and users? interface and search option preferences define the usability requirements, which are matched against Google Images? actual interface and search options. The retrieval method of Google Images is also briefly discussed, and users? opinions about Google Images too, as they come across in the previously published user studies.The findings are that Google Images lack some of the things that users ask for, but it still seems to be the most used image search engine among average internet users and more appreciated than other search engines.

This paper is a literature study on search engine optimization (SEO) considering the leader of the search engine market: Google. There´s an introductory background description of Google and its methods of  crawling the Internet and indexing the web pages, along with a brief review of the famous PageRank algorithm. The purpose of this paper is to describe the major important methods for improved rankings on Google´s result lists. These methods could be categorized as on-page methods tied to the website to be optimized or off-page methods that are external to the website such as link development. Furthermore the most common unethical methods are described, known as ?black hat?, which is the secondary purpose of the text.

A webpage can be perfectly usable but if users are unable to find the webpage it will remain unused. Nine out of ten Swedes use a search engine and the most popular one is Google, amongst other search engines. In this report I seek to answer which ranking factors that should be included in an SEO-audit of an existing webpage and also how to optimize a webpage for search engines. Applying the method heuristic evaluation normally used to discover usability issues in an existing interface, on TT News Agency?s campaign site I found issues having a negative impact on the visibility in Search Engines Page Results.

Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

The aim of this Masters thesis is to understand how librarians develop their reference service. The purpose was to find patterns in how librarians work with reference questions. As a theoretical framework we have used research in the reference field. Where do the skills of the search process come from: education or experience? Answers were sought to the following questions: - How different are the search process in practice compared to theory? - Which similarities and differences are there among the informants? - How important was the education in comparison to the knowledge about the libraries collections? - How did the changes in the school system in 1993 influence reference education and what could the consequences be to the reference knowledge among librarians? We sent out a question form and a search question which was answered by 12 librarians in university and university college libraries.

The aim of this thesis is to contribute to increased knowledge concerning students? information seeking in an electronic environment. Using a qualitative approach; focus groups interviews, a total of nine nursing students were interviewed in two groups. The interviews were transcribed and analyzed with an analysis tool based upon Lucy Kuntz?s, Gary Marchionini?s and Carol C Kuhlthau?s models of the information seeking process.

The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.

The purpose of this MSc thesis is to examine the retrieval effectiveness of two Web search engines with queries from the academic discipline of Classical Studies. The two search engines are chosen to represent two different types Google as a broad general search engine and Argos as a specialised search engine for the subject of Classical Studies. The search engines are compared for precision among the first twenty results returned for thirty queries. In order to avoid bias in the study, the queries are based on real users' information needs. Due to the subjective character of the concept of relevance, the study is performed with five different experiments with five different definitions of relevance.

This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.

iProspect is a global digital marketing agency and work primarily with search marketing. They were the first search engine marketing agency in the world when the company started up 1996 in Boston, Massachusetts, and the first in Sweden to offer services in search marketing after establishing themselves on the Swedish market the following year. iProspect can be found in the södermalm office in south central Stockholm. They are a comprehensive agency within search and offer everything from search engine optimization and sponsored links to advertising on social media. They?re goal is to lead developments in search marketing and to keep ahead of competition.

The theses discuss information seeking with a focus on Google and social networks. Students attending the librarian program in Lund have been examined by means of two methods; diaries and information horizons, where they had to solve a specific assignment. The information horizon as a method contributes to getting a structural perspective on the information search process instead of viewing information search as a procedure. Information horizons use social network analysis.The aim of the theses is to investigate the importance of the social network in information search, with a particular focus on Google as a search tool. Our hypothesis is that Google acts as a compensator to the social network when the students search for information and in the educational program.The research indicates that there is no direct correlation between usage of the social network and usage of Google.

The purpose of this report is to find a model of statistics for construction and demolition waste, which makes it useful for the local manager at the building site. The intention with the model is that it will be used as a support of the local manager, to direct his project towards reduced strain of the environment. The model will also be used to make it easier to control that the claims from authority and aims for the environment are achieved. To familiarise with the subject waste handling within the building and construction sectorI have done a literature search. I have also been studying rules and regulations regarding the waste handling.

The United Nations has, during many years, developed a model for a globally harmonized system for classification and labeling of chemicals, with the aim of it becoming a global standard. This system is implemented in the European Union through the CLP-regulation and is now working parallel to the existing directives until 1st of June 2015, when all the new classifications of substances and mixtures must be completed. The aim of this project was to adjust the laboratory to the new legislation, through inventory of stored chemicals, update the list of chemicals and perform self-classifications of mixtures. The work included handling of about 650 different chemicals with varying hazard classifications and search for information in corporate websites and chemical databases. This resulted in a new and complete list of chemicals stored and used in the laboratory and, in addition, an example of how to make a self classification of a mixture.
