Informationssökning i tre olika hypertextstrukturer - ett experiment

The aim of this study was to find out if hypertext structure has any relevance for the efficiency of information retrieval. An experiment, in which three variants of hypertext structure were compared, was carried out in the autumn of 1998. Three websites with different structures were constructed for this purpose: a sequential version, a hierarchical version and a webcluster version. 44 subjects, all students at the University of Lund, were randomly divided into three groups. Subjects were requiered to answer a number of questions using one of the three versions.

Tidssynkroniserade mätningar i vattenkraftstationer

Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.

Säkerhet till varje pris : En jämförande studie om utvecklingen av privat säkerhet från Kuwaitkriget till Irakkriget

The purpose of this essay is to examine the development of the use of private securitycontractors in Iraq. The reason is that there has been a considerable increase of the number ofprivate security firms operating in Iraq during the last couple of years. The legislation in thefield of private military and security is indistinct and my hypothesis is that the lack of nationaland/or international legislation can be connected to the increased globalization. To come toany conclusions about this I have chosen to make a comparative study between the two casesthe Gulf War and the War in Iraq which started in 2003. In this comparison, I ask thefollowing questions: 1) Are there any signs of anarchy in the field of private security duringthe Gulf War respectively the last War in Iraq? 2) In what way has the use of private securitycontractors changed from Case 1 to Case 2 ?According to my research, there were signs of anarchy in the field of private security bothduring the Gulf War and during the latest war in Iraq.

Verktyg för lönsamhetsberäkningar vid bränslekonvertering av spetslastpannor från olja till pellets

This report summarizes the development of a calculation program estimating the profitability of converting a peak-load oil-fired boiler to pellets. To convert an oil-fired boiler to pellets a new fuel handling system must be designed. Changes also have to be made to some other components. Since there are many different techniques for transportation, storage and treatment of the fuel only the most interesting techniques from Swecos experience and interest were included in the study.The capacity of the different parts in the system was dimensioned based on the power of the boiler after conversion. To estimate prices, installed power and dimensions manufacturers and distributers were contacted.

?Läsa för livet!?: En studie rörande sambandet mellan presentation, genomförande och uppföljning av fiktionstext i gymnasieskolan

The object of this study has been to establish whether there is a correlation between a teachers efforts in presenting, working with and creating a connection to ?real life? when working with fictional texts. A further hypothesis is that presentation, realization and the follow up activities has a correspondence to how well the goals for the lesson are achieved. In order to achieve the presented objects the methods of observation and interview are chosen. Firstly classroom observations are made and subsequently interviews with teachers that struggle with these questions on a regular basis are conducted.

Mellanstatligt samarbete mot människohandel i Europa : ? en studie om mål, åtgärder och resultat

This paper provides a study about human trafficking with sexual motives performed in European states and the measures taken from national, international and Non-Governmental organizations with the purpose to oppose human trafficking. According to the UN human trafficking has increased and shows tendencies to continue escalating, regardless of the measures taken by various organisations. In this study, four countries with associations to human trafficking have been chosen and organisations related to these countries are studied. The purpose is to inquire into how these organisations work against human trafficking and which objectives and guidelines these organisations strive for together with their values. The aim is to find out which result the organizations efforts gets and if, according to my hypothesis, the efforts oppose themselves.

Det föränderliga Sovjetunionen

The objective of this essay has been to show how the image of the Soviet Union in ?Alla tiders historia? differs in the 1989 and 2004 editions of the book. To explain these differences I have used a discourse analytic perspective, mainly inspired by Michel Foucault and his philosophical theories of the constructions of objects, and also Faircloughs critical discourse analysis inspired by Gramsci.In this paper the two editions of ?Alla tiders historia? are presented with quotes which are then analysed from using my theoretical framework. In the 1989 edition three themes emerged: continuity, undecidability and ambivalence, which together present an image of a Soviet Union which is not clearly defined within the political discourse.In the 2004 edition this struggle over the discourse has been settled and the Soviet Union?s position as a dictatorship has been determined, at the same time as the Soviet Union is put in a negative relationship with Czar Russia and is connected with Nazi Germany.

Hur har Schengensamarbetet påverkat främlingsfientligheten i Europas länder? : En studie av sambandet mellan främlingsfientlighet och Schengensamarbetets institutionella förändringar.

The xenophobic attitudes in Europe are stronger than even. Never before have the member states had as many right-wing parties in action. The aim with this report is therefore to consider whether the Schengen cooperation has had an influence on the development of xenophobia in the member states of EU. The Schengen cooperation became a part of the European Union in 1997, with the aim to abolish the internal border controls for citizens and strengthen the external boarders towards non-members. The intention is furthermore to investigate whether the distance to Schengen ?s external boarder has an impact on the xenophobic attitudes.Three countries are compared: Italy, Netherlands and the United Kingdom.

Curlingföräldrar - Från Traditionella Föräldrastilar till ett Modernt Föräldraskap : Uppfostran i ett Förändrat Samhälle

A study was conducted to investigate the new and frequently discussed concept curling parents. There were no previous studies of curling parenting, and therefore traditional classifications of parenting (Baumrind, 1967, 1980; Maccoby & Martin, 1983) have been used for comparison. Parents (N=140) born between 1959 and 1981 participated. They completed questionnaires to establish their level of curling behaviour. The high Cronbach's alfa confirmed coherence in the curlingcriteria, which implied that curling parents exists as a group.The results confirmed our hypothesis that participants exhibiting high levels of curling behaviour were permissive in their parenting style, had a bad conscience concerning their parenting and wished for more time with their children.

Kväveförluster och energianvändning på mjölkgårdar i västra Sverige :

Protecting the environment has with time grown to take a more central role in the society. Agriculture plays an important role in the society since this sector produces our food. More thorough research on how agriculture affects the environment is therefore motivated. This research can be used to improve the agricultural practice from an environmental point of view. This is something that both the farmers and the consumers can profit from. This study aims to form the basis for creating environmental indicators for use of nitrogen and energy on dairy farms. Twenty-three farmers in western Sweden have been interviewed about their farms, both organic and conventional. They produce milk with different intensity, defined as the amount of milk delivered (sold) per hectare of arable land.

Design av stimuligenerator för radarmålsökare

During the development of microwave based sensors such as radar target seekers, input signals are needed to verify the performance of the system. Therefore, a channel board has been developed by previous thesis projects at Saab Bofors Dynamics. It uses a technique called Digital Radio Frequency Memory (DRFM). The purpose of this board is to sample and digitally store radio frequency signals in order to reconstruct them after a certain delay.The aim of this thesis project was to use the channel board named above to construct a portable instrument for generation of stimuli signals. This assignment has been divided into two tasks: firstly, to construct and put together the hardware components and secondly, to implement a graphical user interface for the instrument.

Mätmetoder och nyckeltal: en kvalitativ studie om hur bibliotekschefer mäter bibliotek

The aim of this master?s thesis is to examine how managers in some public libraries are using performance measurements and to what extent decision making is based on the results. The main questions posed are:??What performance measurements and indicators are used in the libraries examined???What is the attitude towards performance measurements among library managers???How and to what extent are performance measurements and indicators used in the process of decision making???What improvement would library managers wish regarding the development of performance measurements in public libraries?The theory is based on a model of evaluation of the public sector in addition to general steps of evaluation of quality and performance measurement results. The investigation is based on qualitative interviews with seven managers of public libraries in Sweden.

En kreativ romans: Konsten att flirta med omtänksamhet

Consumers today are bombarded with innumerable advertising messages. The need for companies to create advertisements that consumers find relevant is thus increasing. In order to break through the ad clutter, companies have to give something extra to their customers and show that they care about them. How a company decides to communicate might then be more important than what the company actually communicates.The purpose of this paper is to investigate whether the use of creative media choices induces signaling effects and enhances advertising value as well as perceived corporate consideration. The two last mentioned variables are explored as potential driving forces behind the signaling effects.

Rysk-georgiska kriget : Rysk maskirovka eller georgisk rundgång?

This essay aims to analyse if the Russian military operation carried out against Georgia between the 7th and 12th of august 2008 were executed with adherence to the Russian principles for military deception, maskirovka.   A superior purpose is to assess the situation according to the Swedish Armed Forces task of identifying possible needs for new or changed needs for abilities and competence.   The method used is two-alternative hypotheses which are tried by comparing actual events before and during the Russian-Georgian war with the ten methods of maskirovka, compiled from military analytical literature. Such traces of resemblance are further examined, both individually and as a part of a larger indication.   Further the essay describes the Russian art of war, the prerequisites for military surprise, information warfare in Russian doctrine, the disputed territories of South Ossetia and Abkhazia and the principles for maskirovka.   The conclusion is that the Russian operation was executed with some adherence to maskirovka, though unspecified of to what degree.   Author of this essay is Cadet Martin Svensson of the Swedish Army, currently a student at the Armed Forces Technical School in Halmstad..
