Det permanenta mätfelet: En studie i förändringen av det permanenta mätfelet

This thesis studies the relationship between book values and market values in different assets and liabilities in Swedish Large Cap companies balance sheets. The aim is to find out if the relationship, the permanent measurement bias, has changed during since Mikael Runstens doctoral thesis from 1998 called The Association between Accounting Information and Stock Prices. Although some changes in the permanent measurement bias are found, this probably is due to other aspects than the introduction of IFRS..

Ström- och temperaturkontroll

Storing kinetic energy in a flywheel allows for more efficient driving of electricvehicles. Research in this area is in progress at Uppsala University, where a flywheelwith magnetic bearings encased in a vacuum chamber is being constructed. To makethis possible methods for measuring the current through the electromagnets in thebearings and temperatures in the flywheel need to be developed. This has been thepurpose of this report. The current measurement resulted in a resistive method, andthe implementation of eight measurement circuits in the system.

Value creation from a gender perspective ? a case study of Caran

Caran has a strong belief that women leaders affect the financial profitability positive. Since women leaders are intangible resources it is very difficult to calculate its exact value. The authors found that one of their measurement methods can?t be used to calculate the value of women leaders. The other measurement method can calculate significance between women and men leaders and provides an index to be compared to other groups.

Del projekt inom ClampCal - Utvärdering av mätmetoder för temperatur, viskositet och densitet samt röregenskaper

The dissertation were performed on SP, Technical Institute of Sweden. The dissertation were carried out on the measurement technical department, this dissertation is a part of a bigger project, project ClampCal. One of SP?s returning assignments are flow-measurement. When flow-measurement is performed, the flow has to be stopped so that a meter can be installed in the pipes where measurement is going to take place. At every stop there is time delay in the flow which causes the customers to loose money. This is why SP wanted to find a better solution so that measurement can be done without any stops in the flow. Usage of a so-called Clamp-on meter was considered, but since the measurement uncertainty is too large it takes some investigation on the parts where the largest uncertainties occur and thus find a solution that can diminish the uncertainty as much as possible. The parts that were considered to have an opportunity to reduce measurement uncertainties were the fluid temperature, its characteristics and the pipe geometry and its characteristics. For the fluid temperature a Pt100-sensor with four different radii for various pipes was used.

Att mäta bibliotek: en studie av två biblioteks verksamhetsberättelser.

During the late twentieth century, political and societal changes gave rise to an increased interest in performance evaluation in public organizations. This development also affected libraries in the public sector. The main concern for this master thesis is performance measurement in libraries. In this study two different types of libraries are investigated, one public and the other academic. My aim is to find out if and how performance measurement appears in the libraries annual activity reports.

Statistik, nyckeltal och mätmetoder ? Vad ger de för bild av bibliotekens verksamhet?

The aim of this Bachelor´s thesis is to investigate how library statistics, performance measurement and indicators represent the modern public library activity. During the last decades the public library has gone through a lot of changes. Information overall has increased and new technology has been introduced into the library. This new development has had effects on the library users. The statistics reported to the Statens kulturråd (National Arts Council) has not changed in the same way.

The aim of the thesis is to analyse and understand resolution, repeatability and reproducibility of the measurement system for package distance. The measurement system for package distance is already in use, no Gage R&R has been performed on the system and before spreading use of the system the quality of the system has to be understood and approved.

Prestationsmätning ur ett kostnadsledarstrategiskt perspektiv : En fallstudie på Gekås Ullared AB

Bachelor thesis, Business Administration and Economics Programme, School of Business and Economics at Linnaeus University in Va?xjo?.Spring of 2015 Title: Performance measurement from a cost leadership perspective - A case study on Gekås.Authors: Adrienn Csiszer, Hannah Lundberg & Helena WennerströmTutor: Eva GustavssonExaminer: Karin Jonnergård Keywords: Performance measurement, Performance measurement systems, Generic strategy, Cost leadership strategy, Financial and non-financial measurements. Purpose: The purpose of this study is to examine how a company with a clear cost leadership strategy chooses to work with performance measurements, with a view to comparing a practical example to theorethical approaches. Methodology: The method chosen for this paper is a case study on Gekås AB. The presented data were collected through interviews conducted with four employees on Gekås. Conclusion: The study concludes that for a business with cost leadership strategy the financial measurements are more important than non-financial meausurements. For Gekås it is important to keep the performance measurement simple and understandable for the employees. They only use three measurements (sales, hours and sales per hour) in planning and in evaluation.

Trä och fukt ? Mätmetoder för fuktrelaterade dimensionsförändringar hos trä och deras användbarhet, med två fallstudier inom konservering

This thesis deals with different methods for measuring moisture-related dimensional changes ofwood. Typically relative humidity is measured to determine if the ambient climate around anobject is harmful to it or not. Values between 40 to 65% RH are recommended for hygroscopicmaterials. To know how a wooden object actually reacts to changes in the surroundingenvironment requires methods that involve the object itself. Because of the wood anisotropy,differences in wood structure, finishes and other restraints, it is not always possible to predict themovements.This paper addresses various measurement methods, primarily methods that have been testedin the field of conservation, with examples of their use.

Faktorer som påverkar sjuksköterskans bedömning och värdering av smärta hos patienter : En litteraturstudie

The aim is to describe the factors that influence nurses' assessment and measurement of pain in patients. Literature study based on 13 reviewed articles, searched in the Cinahl. Qualitative and quantitative articles were analyzed. Six themes were identified that can be seen as the factors that influence nurses' assessment and measurement. The themes were   pain education, nurses´ experience in the profession, nurses´ level of knowledge about pain relief, documentation about pain, nurse´s perspective on the patient, and pain measurement.

Metodundersökning av tre metoder för kvävemätning i en arktisk äng : Jämförelse mellan mätmetoderna extraktion, inkubation och jonbytesmembran (PRS-sond)

The purpose with this report was to compare three commonly occurring methods for measuring plant available nitrogen in soils. The methods extraction, incubation and Plant root simulator (PRS) probe - an ion exchange membrane (Western Ag Innovations, Inc., Saskatoon, Canada) method were used and comparison between these methods were conducted. A full factorial experiment were set up in northern Finland with the treatments excluding herbivores, warming and fertilization to see how the inorganic nitrogen content in the soil was effected by the treatments. Soil cores were taken and from them a subsample was incubated for 18 days and thereafter analyzed for inorganic N in laboratory. PRS- probes were in the ground for 1 month.

Utveckling av ett provtagningssystem för alkohol och aldehyder i fordonsemissioner.

A system for sampling of alcohol and aldehyde from diluted exhaust gases from vehicles powered by ethanol has been developed and tested. The major part of the work has been research of earlier work in the field and the construction of the sampling system.The part of the system constructed for the measurement of alcohol has been shown to work, however, more test should be performed. The part of the system constructed for the measurement of aldehyde was tested parallel to a commercially available system, based on the same principle of measurement, and has been shown to work well.Determination of the concentration of gaseous ethanol using a FID has shown the since earlier known fact that a FID is not able to measure a correct concentration of ethanol. Furthermore it has been shown that high concentrations of gaseous ethanol can not be kept in a bag more than a few minutes without a substantial decrease of the measured concentration..
