Två metoder av finutsättning och dess noggrannheter
This report describes a study of two different methods to achive the best possible result in setting out apartment details. These two methods are the setting out of details with a measuring tape from baselines and the setting out procedure with an instrument (totalstation).Through our knowledge in surveying and mapping technology and help from a carpenter, this investigation has been implemented. The setting out using a tape has been performed by letting the carpenter to set out windows, bathroom and water- and drain-details from baselines and drawing. The setting out using a surveying instrument was carried out by means of a Trimble Total Station. These two methods have been compared in order to detect and show the difference that occurs.The report shows the investigation background story from the practice of Swedish Mätcenter in Karlstad.A result of differences in accuracy and time is described in the report, as well as their theoretical consequences.
Tillståndsskattning i robotmodell med accelerometrar
The purpose of this report is to evaluate different methods for identifying states in robot models. Both linear and non-linear filters exist among these methods and are compared to each other. Advantages, disadvantages and problems that can occur during tuning and running are presented. Additional measurements from accelerometers are added and their use with above mentioned methods for state estimation is evaluated. The evaluation of methods in this report is mainly based on simulations in Matlab, even though some experiments have been performed on laboratory equipment.The conclusion indicates that simple non-linear models with few states can be more accurately estimated with a Kalman filter than with an extended Kalman filter, as long as only linear measurements are used.
Jämförelse av olika metoder att generera Bernoullifördelade slumptal givet deras summa
In this master?s thesis the problem of simulating conditional Bernoulli distributed stochastic variables, given the sum, is considered. Three simulation methods are considered, namely the acceptance/rejection technique, Bondesson?s method and the Markov chain Monte Carlo method.To compare the three methods the bias and the standard deviations of the simulated variables are evaluated. The results of the simulation study shows that the Markov chain Monte Carlo method is not the best method for this type of simulation.
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.
Familjelycka? : En litteraturstudie om föräldrars upplevelser av Postnatal depression.
Postnatal depression (PND) is a condition which affects about 8-15% of recent parents. The cause of PND is unknown but several underlying factors have been purposed through different studies. This descriptive literature review aims to illuminate the parent?s situation when the mother is affected with PND. In search of literature, the databases Medline (via PubMed), Academic Search Elite, Cinahl, PsycINFO, PsycARTICLES and SweMed+ were used.
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.
Bemötande av självskadebeteende ur omvårdnadspersonalens perspektiv : En litteraturstudie.
Background: Patients with self-harm seek hospital care when something traumatic occurred. Self-harm was a way to cure pain and was expressed overdose, cutting, or by swallowing objects. They described that the staff were derisive, didn?t show empathy and engagement. Aim: The aim was to describe factors that effects staffs answer to self-harm behaviour through their perspective.
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..
Vem är du? : En studie om etnicitet och positionering på den svenska arbetsmarknaden.
Research shows that non-european academics are discriminated in the labor market. The purpose of this study is to examine non- European academics narratives about their Job search process. By applying an intersectional approach, this study aims to demonstrate how the interplay of different aspects such as gender, class and etnicity shape the interviewees experience in swedish labour market. A postcolonial perspective is applied in order to contribute to deeper understanding of the discriminating structures that the interviewees deal with.The analysis shows that colonial conceptions are embedded in the validation system and institutions such as employment service. This mechanism affects the interviewees negatively in their Job search process.
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.
Odour-mediated behaviour in codling moth, Cydia pomonella : do fermentation odours affect the attraction and oviposition behaviour in codling moth?
The codling moth, Cydia pomonella is a common pest in apple orchards and can be found worldwide. Feeding by codling moth larvae can cause a substantial decrease in apple yield. Control methods comprise for example the use of pesticides, viruses and pheromones. As a sustainable control method, pheromones have been successfully applied to disrupt moth mating behaviour. Other behaviours like foraging, search for mating sites or host finding could be potential targets for additional odour-mediated behavioural manipulation but need further investigations of the underlying odour stimuli and behavioural plasticity.
Many insects are attracted to the smell of fermenting fruit and associated microorganisms.
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.
En undersökning av Libra IIIs OPAC utifrån två perspektiv
This master thesis is an attempt to study the interface in itself, where the human meets the machine and the problems that can arise. I study a particular interface, namely the OPAC of Libra III. In 1999 IFLA presented recommendations for what an OPAC shall contain, and in one part of my master thesis I compare Libra III with these recommendations from my opinion. In another part of my master thesis I make an investigation where I let five by me chosen persons answer some questions from me, both by doing and verbally. I draw the conclusion that Libra III follows most of the recommendations of IFLA in a sufficient way.
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.
