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.

Mental illness is today the leading cause of long-term sick leave and insomnia, anxiety, depression and burnout are among the most common conditions. The aim of the study was to investigate the stability of these conditions and how this is influenced by gender and age, as well as the extent to which these states are risk factors for each other. The participants were a random sample (n = 2336) from the general population in the age of 18-79 years. The results showed that stable illness was more common among women than men, and that stable illness decreased with aging. The stability itself was not affected by gender or age. Relations between the conditions were bidirectional and they constitute major risk factors for each other (odds ratios, OK = 2.37 to 6.46). The largest risk factor for a condition is, however, previous occurrence of the same problem. Previous burnout was found to be a significantly larger risk factor for future burnout than previous insomnia for future insomnia (OK = 9.63 and 5.74, respectively). The results suggest that insomnia, anxiety, depression and burnout, despite their differences, are similar regarding symptoms and underlying causes. The importance of early interventions to prevent comorbid conditions which are more complicated and more difficult to treat is emphasized..

Managing credit risk might be the single most important business area for any commercial bank. The assessment of "good" and "bad" corporate clients is a important task for a creditor. A bad debtor is a corporate client with hardships in meeting the continous claims (interest payments) that a creditor requires. One way of evaluating or separating a "bad" client from a "good" client is to assess the propensity for the client to file for bankruptcy. This thesis examines 226 firms in the Swedsh market in the quest of predicting corporate bankruptcy.

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.

The purpose of my study is to investigate whether luck egalitarianism can be savedfrom its inability to draw a line between risks which can reasonably be expected to beavoided, and risk which can not. Such a demarcation is of particular importance forthis influential theory of distributive justice, since it serves to judge whether a personis entitled to compensation for a bad outcome of a taken risk, or not. Testing theintuitiveness and coherence of various contending principles for how to separateavoidable risks from unavoidable ones, I conclude that luck egalitarianism seemsunable to draw a clear line between the two kinds of risks. Instead the theory appearsto be dependent on conceptions of a 'normal life', making it remarkably vague.Furthermore, I argue that luck egalitarianism seems unable to manage without takingsufficientarian and utilitarian concerns into account, for the purpose of decidingwhich risks are avoidable, and which are not..

Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.

This paper describes and analyzes how individuals and organizations that operate in careers in communications and marketing deal with the search for employees / employers, and how recruiting managers and recruitment consultants are working to create a match between the parties. The study was conducted on behalf of a recruitment agency that offers services in recruiting and staffing for organizations in communication and marketing. The empirical material consists of ten qualitative interviews from three different perspectives on the labor market, recruitment consultants, managers and employees. The interviews were analyzed from sociological and social psychological theories of organizations and individuals opportunities and strategies in today's western labor market. Conclusions that emerged are that organizations need for decreased amount of tied assets provides increased need for temporary employments.

During 2006 an estimated number of 150 persons are supposed to have been killed in road accidents caused by speed limit violations. Through Automatic traffic security control (ATK) the Swedish road administration (Vägverket) is working towards lowering the number of speed related accidents. By placing the speed cameras on roads they've managed to lower the average speed at those places. The enlargement of the number of speed cameras is based upon knowledge about for example how high the risk is for speed related accidents on the roads. The speed cameras always measure the speed in which every vehicle passes, but aren't constantly activated to register speed violations.

.Syfte: Syftet med uppsatsen är att undersöka sambandet mellan Morningstars rating och framtida avkastning, samt om detta skiljer sig åt i olika börsklimat.Metod: Undersökningen bygger på en kvantitativ metod då vi har samlat in sekundärdata från dagstidningar och Internet. Den insamlade sekundärdatan kommer att ligga till grund för empirin då vi testar sambanden mellan variablerna rating och avkastning, risk och avkastning samt rating och risk. Teoretiska perspektiv: Uppsatsens teoretiska utgångspunkt är den effektiva marknadshypotesen och kapitalmarknadslinjen. Teorin grundas även på tidigare studier av bland annat Morey (2003). Empiri: Med hjälp av statistikprogrammet SPSS undersöker vi korrelationen mellan variablerna rating och avkastning, risk och avkastning samt rating och risk.

Abstract  Title: High-Risk Funds vs. Mutual- Index FundsA study of macro -variables influence on different funds choice Level: Final assignment for Bachelor Degree in Business Administration Author: Moses Yokie & Bo Lemar Supervisor: Ogi Chun & Cheick Wagué Date: 2011-05-25 Aim: The purpose with this thesis is to compare two different types of mutual-index fond and a high-risk fund in relation to the macro variables. The purpose also includes an investigation about if an investor will receives a higher return on high-risk fund than on mutual-index fund in a 10 years period.Method: A quantitative method has been use in this study, where the information has been received from Morningstar. Microsoft Excel has been used to process the collected data in order to calculate the expected return and the risk measures. The result is presented in graphs and tables on the empirical capital, in order to analyse and compare it with the theories and the selected macro- variables to see if there will be any correlation. Conclusion: This research shows that there is no possibility that the macro-variable factors can benefit an investment on high-risk fund or on mutual-index fund in the short run.

The purpose of this bachelor-thesis is to investigate the possible effects of lease accounting on the estimation of bankruptcy. This is done by estimating the risk via prediction models based on accounting ratios for a sample of 43 listed firms in Sweden. Estimation is conducted twice for each firm, once base on unadjusted data as it is presented in the annual report of 2012, and one with data adjusted for operational leases (that is data is treated as if all leases present were to have been reported as financial leases). In the next step it is tested weather the predictive ability of the models is affected by this adjustment or not. For this purpose translation of bankruptcy risk into synthetic credit ratings via interest coverage ratios is done.

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.

Background: Investors use companies? credit ratings as a base in their buy and sell decisions. Companies? credit ratings are also used as indicators of safety in the legislation. This means that credit rating agencies have an important role in the society because they communicate the company?s credit rating to investors and other actors in the society.

The purpose of this study is to examine what motivates people to help others at risk to themselves. The focus is on international aid workers, which in their work put themselves in situations of risk. Earlier research shows that international aid work involves risks such as infectious diseases, violence, death threats, assaults, constant insecurity and risk to be traumatized etc. There is not much research done on what motivates to help others in spite of risks, hence we find this an interesting area. We have interviewed six respondents about the content and character of their motivation and factors that are important for the maintenance and development of this motivation.

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.
