This thesis takes on a broader perspective of the modern age phenomenon we call spam. One of the aims of this thesis is to present and to compare the variety of methods used in the day-to-day fight against spam, as far they have evolved today, but also to present and discuss some alternative methods for suggested future use. The properties of a common e-mail spam are analyzed to show how the components that make up the structure in an e-mail can be used to classify spam. Furthermore I explain the naïve Bayesian classification methods, the signature-based method, the commonly used rule-based method and the challenge and response method and discuss these. The widespread use of blacklists is also explained and a close new variant to blacklisting, Turntide is presented and discussed.

The construction industries are relatively conservative type of business that takes a longtime to adjust for new methods and embrace new ideas. It dose not matter if the newmethod seems to be an improved method as long as it is new and untried. Constructioncompanies are reluctant to change form a longtime working method to a relativelyunknown method.The purpose with our report is to perform an evaluation of BeWi construction method.Our goal are to present the generally opinion about BeWi from the contractors that hasbeen in contact/worked with the method. We also want to know from the contractor?spoint of view if BeWi and the method measure up to the standards that are presented byBeWi and if they believe that improvements need to be done.Our progress up to the final report has consisted of three parts[1]Field studies[2]Interviews[3]Literary studiesWe started out with field studies where we took notes and observed all the includedworking phases on the construction site when using the BeWi method.

The present study examines six young men?s, born in the 1980?s, experiences of their relationships with their fathers. The focus of the study lies on the son?s evaluations of their fathers? influence on them, the men?s emotional language and the experience of the fathers? presence versus absence. The relationship with the fathers and the fathers? emotionality are also being discussed.

One of the most commonly used methods for analysis of polyphenols is the Folin-Ciocalteu (FC) method, where the FC reagent has been reported to interfere with some substances in fruit juices. The interfering substance that is present in the highest amount in most fruit juices is ascorbic acid. In this study, the total phenolic content (TPC) of three fruit juices was analysed by the FC method as well as with an enzymatic method with hydrogen peroxide oxidoreductase type II (HRP) for comparison. To investigate how the interfering ascorbic acid affects the TPC, juice samples were analysed after removal and addition, respectively, of ascorbic acid. The samples were analysed with HPLC both before and after the extraction phase of the FC method.

Background: Oil is the most dominating source of energy of today, it constitutes for more than 40 per cent of the worlds total energy consumption. This together with the fact that stock in oil companies has soared on the stock exchanges around the world makes oil a very interesting topic to write within. In order to gain knowledge in how to value oil companies, the authors will collect information from theory and through a questionnaire. By applying the information gathered to three companies listed on the Stockholm Stock Exchange the authors will reach an objective picture of valuation of oil companies.Purpose: To investigate how shares of stock are valuated in the oil exploring and producing industry, and what specific measures and metrics that are used in the valuation of stocks in Exploring and Producing (E&P) companies.Method: By using a qualitative approach for this thesis, the authors will investigate how the valuation of oil companies works and what measures that should be applied. The authors will use a part descriptive and part explorative study.

In this thesis, the conditions of using the maintenance method live work at the Swedish TSO, Svenska Kraftnät has been analyzed. The study is limited to only include live work on 220 and 400 kV. The live work method is a type of maintenance that can be done, on lines or stations, even though they are still energized. The purpose of this thesis has been to map the present live work situation at these levels in Sweden. The study is based mostly on interviews with people who have specific field competence with in live work but also with personnel at Svenska Kraftnät.

This report presents an investment calculation based on an assumed initial investment of a new saw line to an existing sawmill. In order to get as close to reality as possible, we have received data material from northern forest owners who recently made an initial investment in their sawmill in Kåge. In order to calculate and evaluate investments are several different methods, but we, we have chosen to use the discounted cash flow method. The method sums up with the help of a fixed cost of capital together with any future costs and revenues, thereby giving a present value of the investment. We also do a sensitivity analysis to examine how selected factors affect the investment research they change. The study is carried out to a fictitious investment, and therefore the result should not only be studied as a result of the figures. The purpose of this study was that with the help of an investment calculation studying the profitability of a hypothetical investment, and by means of a sensitivity analysis to study the sensitivity of investment to changes. The result demonstrates that the calculations according to the present value method requires a lot of information of the prospective investment.

This article is about Abrahams Children foundation and its teaching method called IE- method. It?s about how a teacher can use the IE- method in the religion lesson. There were some questions in this article that had to be answered and the questions are:- How is the form of the religion classes when a teacher uses the IE- method?- What happens in the class when you study the interaction and the communication?- Does the student?s participation increase when they work with the IE- method?- What are the advantage and the disadvantage with the IE- method?- Can the teacher use the IE- method in other classes?To get to the ?correct? answer I used many methods like, observation in the class, qualitative interview with the teacher (Lisa Andersson) and with four students (Kim, Erik, Amanda, Patrik) and I also used questionnaire.

Background: Budgets has always been a main factor for the management of organisations. Yet, lately has the role of budgets been increasingly questioned. But how is an organisation managed without budgets and what other alternatives can be used? And can these instruments work more effective?Purpose: The purpose of this essay is to describe how non-budget management distinguish compare to traditional management and how to design an effective non-budget system of management. Furthermore we intend to explain the reasons to such management and to present a model for how such a management can be performed.Research method: Empirical material has been performed based on seven interviews with persons within Svenska Handelsbanken.

Traditionally, rolling mills use emulsions based on a mixture of oil and water for lubrication. Since two years ago SAPA has been using (instead of oil) a synthetic lubricant so called conditional emulsion for hot-rolling of aluminum. This lubricant is water based and homogenous at ambient temperature, but switches to a two-phase system at heating above the cloud point.This project aims to validate and if necessary modify an existing HPLC method for quantifying two out of three key components (A, B and C) in the conditional emulsion. Attempts to develop a method to quantify the pH adjusting components, X and Y were also made. These two methods are required to optimize the lubricant.Due to the complexity of the components, it has been difficult to present a method for quantification, and HPLC with ELS detection was chosen after a long series of trials.

As the number of people owning a smartphone rapidly increases so too does the opportunity for various researchers to exploit this technology. The possibility to recruit people to participate in research studies improves and with it the chance to get more diversified target groups in terms of age, socio-economic status, geographical location, etc.In this essay, I argue that the opportunities smartphones offer in terms of collecting research material is vastly underestimated in several areas, bearing in mind the advantages they present. In order to support my argument, I shall present a case study carried out in the research area of happiness ? an area where the use of smartphones has provided significant opportunities for research.In order to gather the advantages and disadvantages of this method of study from the participants? perspective, I have followed a happiness research study which is a collaboration between Umeå University and The University of Stockholm. I have interviewed the participants of this study in order to assess the advantages and opportunities that smartphones offer in research programs.Overall, the participants? opinion of this research method was generally positive and it was considered to be quite easy to participate in the study and respond to the questions asked.

The projects objective is to find an alternative method of heating (the current method being via electric heating) the sewage treatment plant on the island Utö in Stockholm?s archipelago in order to reduce the energy consumption and ultimately the cost for heating the plant. The project is given by ?Skärgårdsstiftelsen? (The Archipelago Foundation) and is a part of the larger EU-project ?Green Islands?.A model for the plants total heating demand is established in order to get a good perception of how much money can be saved using alternative heating methods. The heating demand model gives an annual heating demand of approximately 32 500 kWh and a maximum heating power demand of around 24,7 kW.

This thesis is an investigation of Iranian immigrants and their use of libraries in Sweden. It isbased on a combination of a qualitative and a·quantitative method.Using a qualitative method, I give an outline of the history of lran from ancient times up to the present, as well as the different ethnological groups in Iran and their cultures. The main objective of this part is to clarify the contrasts between Iranian and Swedish cultural, social, linguistic and family structures, and also the characteristics of the crisis that most immigrants go through on their arrival in the new country. The qualitative method also involves structured telephone interviews with eight highly educated Iranians.This method was supplemented by a quantitative study through questionnaires of the attitudes· of lranian immigrants to libraries and reading. Iranians in Sweden turned out to be frequent Iibrary users.
