Inrapporteringsprocessen av förädlingskostnader för Scanias kalkylbilar

In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.

Översättning och validering av pVHI : för barn 6 till 10 år

Studies indicate that between 6-9% of all children has some type of voice problems. Voice problems in children may have different etiology and can affect all ages. In Sweden, there is a lack of a standardized questionnaire addressed to children with voice problems and their legal guardians. The purpose of this study was to translate and validate the Pediatric Voice Handicap Index (pVHI) in Swedish children aged 6 to 10 years. The study was carried out through an internet-based assessment form for children referred to speech and language pathologist/ phoniatrican due to voice disorders in Sweden and a matched control group of children without voice problems.

Noggrannhet vid låghöjdsfotografering från obemannad heliumzeppelinare

The development in photogrammetry has created possibilities for new methods in aerial images acquisition. Remotely-controlled imaging from an unmanned helium zeppelin is a new and relatively unexplored acquisition. The purpose with this degree project is to evaluate the accuracy of this kind of low-height photographing system, a task given from the consultant company WSP, in Sweden. Landbadet in Uddevalla municipality was chosen as a test field for the zeppelin. Seventeen images distributed over three strips were acquired from the flying height of 80 m.

Verksamhetsstyrning fo?r lokaleffektivisering inom kommunal verksamhet : ? En fallstudie av Halmstad kommun

Title: Management control of facility efficiency in municipalities - A case study of Halmstad municipalityLevel: BachelorSeminar date: 2012-05-31Authors: Markus Nilsson & Sara MattssonAdvisor: Sven-Ola CarlssonKey words: Control management in municipality, facility efficiency, management by objectives, internal rents and incentivesBackground: The public sector owns and manages a large property portfolio and in the municipalities, the properties are always a big cost item. Because of the outside world changes and the public interest, the properties should be used as efficiently as possible.Purpose: The purpose of this paper is to describe how control management of facilities looks like a municipality. The paper also seeks to explain how employees work to make the facilities more efficient in a municipality.Methodology: The authors use a qualitative method with open interviews.Theoretical perspectives: The choice of theory was made with the field of management control and facility efficiency in mind. The theory therefore includes management by objectives, internal rents and reward systems, motivation and communication within organizations.Empirical foundation: The organization has undergone a reorganization 2010/2011. There are no clear incentives to reduce facility costs.

Modellering och reglering av drivenheter i gaffeltruck

To enable the enhancement of the driver's environment in a forklift, an alternative form of steering has been evaluated. An earlier concept with a combined driving and steering wheel has been exchanged to a concept with two driving wheels. A link wheel has replaced the combined driving and steering wheel. The steering is done through differentiation of the velocities of the two driving wheels. The scope of this master thesis is to create a simulation model, create a control program and to evaluate the concept of two driving wheels.

Trafikverkets effektstyrningssystem - EFS 132 kV : Bidraget till minskade förluster

The technological legacy from the early electrification of the Swedish railroads has resulted in a power grid with a lower grid frequency than the national power grid from which it is fed. Energy transfer between these power grids with different frequencies requires substations, adapting the grid frequency for the rail road power grid. For this purpose, a feeding power grid has been built, stretching across the country from Boden in the north to Tälle/Häggvik in the south.Power transfer in the Swedish power grid results in voltage angle differences which increase with increasing loads and transfer distance. These voltage angle differences are transferred from the power feeding substations to the rail road power grid, will in some extent cause loss of energy due to unwanted power flows from north to south.To minimize the losses due to this phenomenon, a power management system called EFS 132 kV has been developed and implemented. The system minimizes the unwanted power flows and controls the desired power flow for a good distribution of loads between the power feeding substations.This thesis investigates the extent of the transmission losses avoided due to the EFS 132 kV that coordinates the idling angles to a common reference point.The results indicate that EFS 132 kV affects the power flow, especially between the northern substations through an improved load distribution.

Orsaker till kalvningssvårigheter och dödfödslar hos SLB och SRB

Difficult calvings and stillborn calves are costly for the producer and lowering these frequencies can decrease the costs for the dairy operation. Each calving in the herd is registered by the farmer and stored in a central database. The information is used to monitor the level of calving-difficulties and stillborn calves in the herd and nationally. Monitoring of these registrations is important to detect possible changes. Breeding-value prediction for calving traits is based on the calving information in the database.

Rytmterapi som behandlingsmetod vid stroke: en pilotstudie

Stroke is caused by a bleeding or infarct in the brain and is one of the most common diseases in Sweden today. The purpose of the study was to evaluate if Ronnie Gardiner?s Rhythm Therapy (RGR-therapy) has any effect, regarding motor control and the subjective experienced health related quality of life, on people who have been affected by stroke. The examination group consisted of eight people. The intervention consisted of RGR-therapy once a week during a period of nine weeks.

ADHD som meningsskapande diskurs : om ADHD i socialt arbete i kriminalvården

The aim of this study is to discuss the diagnosis ADHD as a meaning-making discourse that is something more than just a diagnosis with a set of symptoms. I aim to discuss that the diagnosis is productive and can be seen as a means to control and to comfort individuals. The research was based on a method consisting of an idea analysis and a discourse analysis. I am using both a discourse analysis and a critical ideology analysis as perspectives. These perspectives are also based on a general theory of late modernity.
