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.

Mozzarella : En djupdykning i ostmassan

Worldwide consumption of cheese has increased over the years. The average Swede consumes somewhere around 20 kilograms of cheese per year, which is an increase of a 100 % over the past 50 years.

Arbete med läs- och skrivutveckling i grundskolans tidigare skolår : Två pedagoger berättar om sina arbetssätt

The purpose of this paper is to examine how teachers choose to work with the teaching of reading and writing skills, how teachers justify their choice of teaching method and how the documentation of student development is being used. This paper also discusses the definition of reading and writing, phonological awareness and how different reading- and writing educational methods can be combined. The gathering of information has been done through a literature review in which I have looked at past research on reading and writing. I have also conducted qualitative interviews with teachers involved in literacy learning. The result of my research shows that it is not possible to determine which literacy learning methods that are most effective.

Evaluation of Xilinx System Generator

This Master?s Thesis is an evaluation of the software Xilinx System Generator (XSG) and blockset for Matlab. XSG is a module to simulink developed by Xilinx in order to generate VHDL code directly from functions implemented in Matlab. The evaluation was made at Saab Avionics AB in Järfälla, north of Stockholm. In order to investigate the performance of this new module XSG to simulink, a model of a frequency estimator often used in digital radar receivers were implemented in Matlab using XSG.

Hälsoekonomiska utvärderingar - En litteraturöversikt om använding av konstnadseffektivitetsanalys inom folkhälsoområdet

Introduction/Background: Economic evaluations help decision-makers to make informed decisions regarding resource allocation. Information generated from CEA can support evaluations of a new intervention with current praxis. The evaluations also provide information as to whether an intervention is cost-effective, both in economic terms and in health gains. Objective: The aim of this thesis is to investigate the use of economic evaluations in public health, with a focus on CEA. Use of economic evaluations is regarded as both a method for evaluation and as support for informed decisions.

Lingvistik och användbarhet i sökmotorer

This is a master thesis from Uppsala University in collaboration with B Locket AB (more known as www.blocket.se). B Locket AB is a large ad-company from Sweden, located in Stockholm.Search engines on the market today are becoming more and more complex. When they were first introduced, they only had one function and that was to produce search results containing the string that the user had typed. Today, users want it to be able to spellcheck, produce more results and sort search results on specific fields as well. Preferably, all these features should not affect the performance as a whole.The reason to why these demands have come up is that users are getting more and more used to internet services as a whole and they want everything to be as easy as possible.The user ability has become a substantially more important area in the computer industry and this needs to be taken into account when it comes to B Locket AB and its search engine.

Life Cycle Cost : Studie om LCC som verktyg att utva?rdera geoenergianla?ggningar

Life Cycle Cost, often abbreviated as LCC, is a common tool for comparing the total cost of different alternatives, such as heating and cooling methods. Common heating and cooling methods in Sweden are geothermal energy, district heating and district cooling. This report aims to evaluate how different heating and cooling methods differ from each other while being applied on three different types of buildings, using selected LCC-models. Information about the selected LCC-models wasretrieved from each separate model and its website. Reports and agencies were used as sources for information about the heating and cooling methods.

OLED : Evaluation and clarification of the new Organic Light Emitting Display technology

Organic Light Emitting Displays (OLEDs) are a new type of thin emissive displays predicted to possess superior properties to existing techniques e.g. Liquid Crystal Display (LCD). The main advantages are low power consumption and a thin display structure. This report contains an explanation of the emissive OLED technology, its functionality and the physics of the organic layer structure in an OLED. The technology is described with respect to the two classes of organic materials used in displays, small molecules and conjugated polymers.

Odlingsmetodernas påverkan på vitaliteten hos Prunus avium :

The objective of this study was to get a better understanding of how the cultivation methods influence the vitality in Prunus avium. The purpose was also to examine if there was any differences in shoot growth and trunk expansion depending on the method of cultivation. To find the answer to this question a literature study and a case study has been done. The literature study concerns the concepts vitality and stress. Different definitions of these concepts are shown and their connection whit establishment is explained. In the background the species Prunus avium, and the four method of cultivation that are included in this case study are described. Measurements of the shoot growth and trunk expansion were made in this study, and as a complement to these methods, a visual estimate of the vitality was made.

Triage - hälsoekonomi : resursallokering och kostnadsberäkning för olika proriteringsnivåer inom akutsjukvård

When a person arrives at the emergency ward at the Uppsala University Hospital with his or her symptoms he or she explains the problems and then a priority process starts. The staff evaluate at which emergency level the patient is located in a model called Triage. The Triage model helps to decide the priority need and is based upon templates which point out in which of the 5 categories a patient is to be placed, to eliminate any future risk regarding his or her health. A lower triage level means lower priority but implies better health when the evaluation takes place. To obtain optimal effect of the Triage model the evaluation of symptoms must be reproducible so that patients with the same symptoms are placed at the same triage level regardless of whom among the staff conducts the evaluation. The purpose of the study was to see if the resources are allocated based on priority level of the patients.

Rysk vilseledning - ett gammalt koncept i ny uniform?

The Russian operation on the Crimean peninsula has been referred to as a victory enabled by the operationalization of the concept of New Generation Warfare. According to some military theorists, this concept and its operationalization cannot be characterized in terms of the traditional wars waged up to this point. It is, however, also argued that this new generation of warfare is primarily a new approach to strategy, a new way of applying traditional methods to achieve political goals. The purpose of this study is to discern whether Russia employed strategic deception in its operation in Crimea and if this is the case; what methods and principles were used and if these can be explained using a traditional view of deception. The application of theories on deception by Michael Dewar and Barton S.
