Verktyg för mätning av tjänstekvalitet på bredbandsnät
Operators and Internet service providers invest in broadband to be able to deliver new services that require higher data transmission rate. A way to make this possible is to use ADSL, Asymmetric Digital Subscriber Line, as the access technology. To be able to handle this technology, the service providers should do a pre-qualification. Methods and tools are needed to analyze the local copper lines and decide if these qualify for ADSL with respect to service availability and possible bandwidth through the lines. This report brings up some methods for pre-qualification of ADSL, the important quality parameters and how to gather them from the available services today.
Binär matchning av bilder med hjälp av vektorer från deneuklidiska avståndstransformen
This thesis shows the result from investigations of methods that use distance vectors when matching pictures. The distance vectors are available in a distance map made by the Euclidean Distance Transform. The investigated methods use the two characteristic features of the distance vector when matching pictures, length and direction. The length of the vector is used to calculate a value of how good a match is and the direction of the vector is used to predict a transformation to get a better match. The results shows that the number of calculation steps that are used during a search can be reduced compared to matching methods that only uses the distance during the matching..
Validation of realtime-PCR of Fusarium avenaceum for detection in wheat
Mould is a common contamination in cereals. The growth of mould can stimulate mycotoxins production andsome of which at critical concentrations cause health problems in humans and animals. Fusarium is one of thefungus species that has been found in crops and can cause major problems for farmers such as reduced harvestand economic losses. A group of Fusarium species, Fusarium avenaceum, Fusarium poae and Fusariumtricinctum express a mycotoxin, enniatin. The limited information available today about enniatin-forming fungiis that they grow out on fields of wheat in colder climates.
Kundrelationer och kundlönsamhet: En fallstudie av ett modeföretag
This thesis studies the customer relationships and customer accounting methods used by a Swedish fashion company. The aim is to test the empirical applicability of the relationship based framework developed by Lind and Strömsten and to explain potential differences between empirical observations and theory. The framework is based on the categorization of four customer relationship groups and the appropriate customer accounting methods to be used for each relationship. The fashion company, that recently assessed the profitability of its customer base in an aim to implement a new customer strategy, is the object of the qualitative case study. The case study reveals that all customer relationships are to be found at Whyred, except the connective customer relationship.
Total organic carbon (TOC) and chemical oxygen demand (COD) - Monitoring of organic pollutants in wastewater
Total organic carbon (TOC) and chemical oxygen demand (COD) are two methods used for measuring organic pollutants in wastewater. Both methods are widely used but the COD method results in production of hazardous wastes, including mercury.The purpose of this study was to validate the method TOC that will replace COD and find a factor to convert TOC to COD. In this study 26 samples were analyzed from four sewage treatment plant in the municipality of Enköping.The results show that the COD method could be replaced by the TOC method.The factor for COD/TOC was between 3.1 - 3.3. Both methods will be used in parallel until 2013 when it will be forbidden to use the COD analysis..
Hur man genom kreativt arbetssätt kan gynna barn med läs- och skrivsvårigheter.
Abstract People who have problems with the written language will face serious difficulties in todays society. Our social structur is based on the criterium that every individual has to be able to read and write, and for this reason it is important that pupils with learning difficulties receive help. The purpose of my investigation is to examine how children with reading- and writing difficulties can benefit throught creative methods. Children with reading- and writing difficulties are in need of these creative methods that exist today. Amongst all of our public healht issues, dyslexia is one of the biggest problem we have today and children are therefor in need of these creative methods. Through qualitative interviews with two educationalists there has been established thad the creative way of working benefits children in many ways if it is preformed correctly.
IT-konsultens konsultationsprocess
How does IT-consultants reason in their consulting process regarding the
development of a clients IT-based internal recruitment system?
The purpose with this paper is to investigate how an IT-consultant is reasoning
in a consulting process and investigate whether consultants are using
established models and methods in their work.
We have chosen to work with a qualitative examination to attain our purpose. In
our work gathering the empirical facts we have been working with a case study,
an observation and a simulation exercise. The combination of these has made it
possible to carry out the paper and produce the most correct data possible.
Conclusion: We state that IT-consultants do not use any theory-based methods,
they use process methods created by themselves and their company.
Evaluation of ELISA and rapid test for the analysis of fecal Calprotectin
ABSTRACTBackground Calprotectin is a protein found in the cytoplasm of neutrophile granulocytes. In the course of inflammatory bowel disease (IBD), calprotectin is released during chronic inflammation in the gut. Activation of neutrophils during the inflammation is followed by activation and secretion of pro-inflammatory molecules such as calprotectin. Calprotectin is stable in stool up to 7 days and can therefore be used as a non-invasive marker for diagnosis, treatment and measurement of the disease activity in patients with IBD. The most common method for analysis of calprotectin concentration is ELISA.
A targeted evaluation of OpenEye?s methods for virtual ligand screens and docking
The process of drug discovery is very slow and expensive. There is a need for reliable in silico methods; however the performance of these methods differs.This work presents a targeted study on how the drug discovery methods used in OpenEye?s tools ROCS, EON and FRED perform on targets with small ligands. It was examined if 12 compounds (markers) somewhat similar to AMP could be detected by ROCS in a random data set comprised of 1000 compounds. It was also examined if EON could find any electrostatic similarities between the queries and the markers.
Undersökning av mätsystem och regulatorstrukturer för industriella tillämpningar
This thesis is divided in to two different parts. The first part includes examination of the measurementsystem of an industrial robot using a resolver sensor. The main focus is on methods for suppressing noise in the angularvelocity signal without increasing timedelay. Five different methods are investigated. Three of these are based on oversampling: burstsamplingmethod, meanvaluemethod and correlationmethod.
Flödesmätning i vattenkraftverk : Studie av alternativa mätmetoder
Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.
Utvärdering av digital flygbildstolkning & automatisk beståndsindelning för det praktiska skogsbruket :
To be able to plan different treatments, accurate data is required. The collection of data is often expensive and that?s why the aim is to lower the inventory costs without loosing the accuracy of the data. Holmen Skog has in its strive to lower the costs, decided to evaluate two different methods for forest delineation, computer aided forest delineation and digital stereo view. This study?s purpose is to evaluate these two methods in regard to usability for a beginner and how good the delineation gets.
En analys av Hosni Mubaraks sista tal som Egyptens president
On the 10th of February 2011 Hosni Mubarak gave his last speech as the president of Egypt, on the following day he resigned the presidency after more then two weeks of violent protests against his rule, and with that his 30-year long rule over Egypt had come to an end. This bachelor thesis aims towards examining this speech using both qualitative and quantitative research methods in order to reach a useful analysis of the speech. The conclusions of this thesis is that several methods were used in the speech in order to win the listeners acceptance and approval for the speaker, and then to use these in order to soothe, or preferably to completely stop, the current revolution. The methods that have been found to play major roles in achieving this are; portraying the speaker, defining the listener, promises of improvements and of justice/revenge, and nationalism. This thesis is written in Swedish with Arabic excerpts..
