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.

Denna studie vill ge större inblick och förståelse för individen bakom den kriminella stämpeln, samt bringa insyn i dessa individers egna tankar om sina kriminella handlingar och kampen ut ur kriminaliteten. Avsaknaden av tron på att personliga livshändelser sker utifrån egna handlanden, där personen istället agerar passivt offer i sitt liv är något som återfinns hos interner. Motsatsen till detta är personer som tror på sitt eget handlande, det vill säga internal locus of control. Denna uppsats belyser kriminellas bakgrundshistoria till uppbrottet ur den kriminella livsstilen med fokus på locus of control, vändpunkter och framtidsperspektiv. Tio personer deltog, varav åtta män och två kvinnor i enskilda semistrukturerade intervjuer.

Heart failure is an illness that requires life-long treatment and often affects everyday aspects of a person?s life. Self-care is a significant part of the treatment. Good self-care resources make it possible for people with heart failure to make the lifestyle changes they often need to maintain or improve their level of health. Self-care means having knowledge of and being able to recognize the symptoms and signs of deterioration that can occur with heart failure, so that the person can take appropriate measures ? and it also means knowing when it is time to seek professional help.

Dagens samhälle är ett informations- och kunskapssamhälle där kunskap och kompetens är nyckeln till företags framgång. En förändring har skett i näringslivet då de tillverkande företagen har blivit allt färre och de kunskapsbaserade företagen har ökat. För att kunna överleva i det nya samhället måste ledning och anställda i ett kunskapsbaserat företag ständigt utveckla sina kunskaper, sitt humankapital. Humankapitalet är den mest värdefulla tillgången i ett kunskapsbaserat företag då företaget är beroende av de anställdas kompetens och kreativitet. Därför är det viktigt att dessa företag tar tillvara på och förädlar sitt humankapital.

During the last years around 100 000 immigrants have arrived to Sweden, people with different reasons and different goals for settling down in Sweden. The reason for immigrating to Sweden that will be dealt with in this thesis is following immigration, i.e. when someone moves here because they have relatives living in the country.The reason why it is interesting to study following immigration is that it is an affecting factor for how many that will immigrate to Sweden the following years and may then be used to make a forecast, based on how many first time immigrants there are. To be able to investigate the following immigration analyses are made with time series, logistic regression and Poisson regression. An ARIMA-model has been used to estimate the number of following immigrants in the future.The other part of this thesis will inquire the matter how inclined immigrants are to become Swedish citizens, whether they even apply for citizenship and also how long time it takes from the time when they fulfil the conditions for Swedish citizenship until they apply.

This work is an experimental study where knock sensor placements are investigated using engine tests. The aim is to studythe quality of the signal from knock sensors and how the signal for engine control is affected at different sensor locations on Scanias, engine DC13. To find out at witch position on the engine youcan get a usable signal for engine control, the engine is running while the knock sensors with advanced measurement equipment is connected to the engine. Evaluation of signals from the knock sensors are made in the computer program Matlab. The program is producing a seriesof plots, from these plots it is visually possible to draw conclusions and find connections.

SummaryBackground: Management control is important for all kinds of activities, both in trade and industry and in the public sector since you must economize on scarce resources. There are nevertheless many different views on management control, which have changed with the times. With regard to the public sector in Sweden, the management control systems have changed radically the last half century, especially from the 1980s, due to depressions and increased focus on effectiveness. New approaches have been taken by many municipalities and county councils, both in Sweden and internationally, where the former management control systems have been abandoned in favour of result control, target costing, and activity-based-costing, for example. Another new approach has been the Balanced Scorecard, which was introduced by Kaplan & Norton in a pioneering article in 1992.The Balanced scorecard is a multidimensional tool, originally intended to be used in trade and industry, but with regard to its nature, it has been adopted even by many non-commercial organizations, especially in Sweden.

Previous research in the area of leadership and stress has shown that the leader plays an important role but in what way is still an issue to explore. A qualitative approach was used in this study to develop an increased understanding of the leader's experience of stress using four themes; leadership, stress, control and organizational factors. A total of 12 semi-structured and un-structured interviews were carried out with 6 leaders, three females and three males. The data was transcribed and thematic as well as narrative analysis was conducted.The results indicates that leadership stress is caused by a lack of control and that factors intrinsic to the role as a leader both facilitates and complicates the leaders situation when facing stress..

In recent years, moisture damages have been noticed in rendered, undrained stud walls. The design is built on the principle one-stage tightening which means that there is no air gap in the construction. The damages have occurred when water has permeated through the rendering in leaking connections and fittings for windows, doors, canopies, balconies, terraces and awnings. Behind the plaster carrier, which consists of either polystyrene or rigid mineral wool, plasterboard has often been used as a wind protection barrier. In many cases the wind protection barrier and the underlying wooden studs have been exposed to mould and in some cases even rot.

Purpose: The purpose of this paper is to examine if companies? incentive programs for employees is designed in such a way that it makes it possible for managers to reach their goals. Method: Qualitative with a semi standardised questionnaire Results: Our results is that the incentive programs for employees in their present form don?t give the companies a good possibility to effect the employees to perform towards the goals of the system. The performance measures in the incentive programs for employees is suitable in comparison with the goals of the program but the construction and the use of the systems doesn?t give a satisfied result in comprising with the goals.

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.

Fruit flies (Tephritidae) are serious pests that cause enormous losses for farmers in many countries. The frequent use of insecticides in controlling fruit flies in fruits and vegetable has not resulted in sustainable management of the pest. Problems associated with this complete reliance on chemical control are many residues of insecticides in crops, health problems for farmers, contamination of water and soil, insecticide resistance development and decrease in natural enemy populations. The implementation of control measures that do not imply an added burden to the environment and/or the farmers is urgent. More knowledge about the ecology of fruit flies is the basis for finding new and better ways to control this pest.

Around the 1950s an explosive population growth started in the Third World. Parallel with the population growth a global network grew up advocating population control and limited population growth. Sweden had a unique place in that network through a pioneering role promoting the issue in the UN organization. During the 20th century Sweden was a pioneer country in terms of initiatives for population control. Ceylon family planing pilot project was something new in a time when other donors considered family planning be too controversial area for bilateral aid projects.
