Att göra eller inte göra : Hur kontroll och nyfikenhet påverkar regelverket på Facebook
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.
Informationslogistisk modell : Hur ska tillverkande företag tillgodose informationsbehoven?
This essay answers the question: How can a manufacturing business fulfill the information demand in the processes; purchasing, production, warehousing, order and delivery?The question has been answered through different kind of studies, such as literature, documents, Internet search, interviews and observations. The essay is written from a hermeneutic point of view and by using qualitative research. The result has been validated by two different manufacturing businesses.A simple information logistic model is the result of a comparison made between theory and empery. The aim of the model is to describe how a manufacturing business can fulfill the information demand by using different methods.
Framtagande av metoder och rutiner för säkerställande av kompetens : inom miljö, arbetsmiljö och kvalitet
The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.
"Fördjuparen" och "Uppdateraren" - nya mönster för nyhetsanvändning för unga vuxna
AbstractTitle: The ?Investigator? and the ?Updater? ? new patterns of news use among young adults.Number of pages: 48Author: Anna StrinnholmTutor: Amelie HössjerCourse: Media and Communications, D- levelPeriod: Fall of 2005University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: The aim of this essay is to provide an description of how daily newspaper, TV, radio and the Internet are used by young adults in order to contribute to Lennar Weibulls model ?a typology of the Swedish mediasystem from an audience perspectiv?.Method/Material: The method of gathering of empirical material has been conducted by interviewing eight people of how they use daily newspapers, TV, radio and The internet to inform themselves of the daily news. The empirical material has then been analysed by applying a two step method, of first making a summary of the interviews and secondly making a comparison with a model of Lennart Weibull ?a typology of the Swedish mediasystem from an audience perspectiv? .Main results:Two different types of ideal media users can be drawn from the empirical research, the ?Investigator? and the ?Updater?. The updater search for news to stay updated and relies on the Internet as main source of information.
Standardisera mera? : Z39.50 mellan enighet och mångfald
Z39.50 is a standard protocol designed to create an interface between diverse computer databases for diverse information needs. Since it has to be adjustable it is also complex and demands a certain degree of expertise when being set. However, the aim of this paper is not to make a theoretical description but to examine certain conditions in practice. From the perspective of Swedish research libraries two principal hypotheses are examined: 1) the implementation of a given technology (Z39.50) is primarily influenced by social circumstances, and 2) the way in which the technology is implemented will bias the results of information retrieval. For this examination we need a framework of theories concerning the relationship between technological development and society, organisational theories and database theories.
Annonser i nättidningar ? kvalitet och placering i målorienterad sökning
This study investigated how banner ads, depending on its quality and placement,can capture a user's attention while searching for editorial content in an online newspaper. Furthermore, the user's search strategy was also studied to see whether it varied depending on the placement of an ad. An experiment was conducted where 20 subjects searched for articles in a Swedish online newspaper while their eye ovement was recorded with a headmounted eye?tracker. In each search task the online newspaper contained either a low quality ad or a high quality ad.

Komvuxstuderandes informationssökning
The purpose of this study is to examine how adult students, studying at an upper secondary school for adults, search for information for their independent tasks in different subjects. These independent tasks are frequent in most subjects and are a part of the ?investigation-work?. For most adult students this is a new way of learning. Fifteen qualitative interviews with adult students have been conducted.
Identitetssökandet hos unga flickor i 2010 års barn- och ungdomslitteratur
My ambition with his exam is to study how young girls are being depicted in swedish novels of 2010. I have analyzed how the identity and the search for identity are produced in these books. To be able to make my analysis of these books I have used Maria Nikolajeva?s book Barnbokens byggklossar. From wich I have worked out a few questions that I have used my analysis in the portrayal of these girls.
Industriforskning och informationssökning: en användarstudie av en grupp forskare vid ABB Corporate Research
The thesis aims at, from a user perspective, examining how a group of industrial researchers understand the information seeking in their every day work. A qualitative method is employed. The empirical material consists of open-ended interviews with in all ten researchers. All of them work at the Swiss-Swedish Technology Company ABB's research laboratory in Västerås. The thesis is based on the opinion that the scientific knowledge production has become commercialised and that the scientific communication is going through certain changes.

Mätning av abrasivflöde för vattenskärningsmaskiner
The content of the following report is the summarized result of three students
thesis at Blekinge Institute of Technology in co-operation with Water Jet
Sweden AB.
This report will give the reader a description of principles how to measure the
abrasive mass flow in a waterjet cutting system.
The work began with a visit to Water Jet Sweden AB to get a closer look at the
problem. When the analysis of the problem was done the criteria were defined in
the form of demands and desires. The main task of the criteria was to guide the
search for the solution. The work proceeded with an extensive search for
abrasive flow meters along with obtaining information about flow measurement in
general. When the search for abrasive flow meters resulted in nothing all the
efforts were concentrated on finding a principle of measurement that could cope
with the criteria.

Lokal sökalgoritm för initiering av den genetiska populationen i ett praktiskt "vehicle routing"-problem.
Befintliga studier har påvisat att genetiska algoritmer presterar bättre om de ges en bra startpopulation. I denna rapport presenteras en lokal sökalgoritm för att skapa en population med fokus på ?vehicle routing?-problem. Algoritmen använder sig av heuristik i en blandning av simulated annealing och tabu search för att skapa individerna till populationen. Utvärderingar av algoritmen på ett praktiskt problem visar att den ger en bra start jämfört med en slumpmässig startpopulation, vilket är vanligt att använda.
Den svenska arbetslöshetsförsäkringens effekter på långtidsarbetslösheten
This is an examination of the Swedish unemployment insurance system and the effects it has on the Swedish long-term unemployment. A search model is explained to give an understanding to the incentives of the unemployed. Different mechanisms that create unemployment and that could create long-term unemployment are investigated, but primarily the unemployment insurance is in focus.The Swedish unemployment insurance has undergone several changes the last fifteen years that have improved its efficiency. The introduction of a finite duration of unemployment insurance entitlement was an important step and so was the decrease in the replacement ratio. Even so, I assess that there is still room for improvements of the incentives to search for work among the unemployed.
