The last years? financial situation has contributed to an increased willingness from the banks to handle risks. The most important risk to cope with is a risk that is related to a customer?s ability to repay loans. Forecasts indicate that in the future, Swedish farmers will be facing profitability challenges, which points to a need to reconsider the banks procedures considering risk management in credit granting for agricultural businesses.Today?s risk management will be given two complements in this study.

This paper describes a study examining four different GARCH models AR(1)-GARCH(1,1), AR(1)-EGARCH(1,1), AR(1)-APGARCH(1,1) and AR(1)-GJR-GARCH(1,1), and their ability to predict future volatility and thereby providing more reliable estimates for Value-at-Risk. The study is based on daily observations for the return of the OMX Stockholm 30 Index, during the time period 31st December 1996 to 29th December 2006. The coefficients for these GARCH models have been estimated using a five-year rolling estimation window, with one-year lags, for five different in-sample-periods. These five in-sample-periods, and the coefficients given by them, have been used to generate five out-of-sample predictions for the volatility in each year. Using these volatility predictions, the daily Value-at-Risk has been calculated for confidence intervals of 90 percent, 95 percent, and 99 percent, respectively, during the time period between 1st January 2001 and 29th December 2006.

During consultation procedures between forest owners and the Sámi, data on, e.g., reindeer lichen biomass on the current site is needed. Hitherto, the existing methods of measuring lichen cover and biomass has been either objective methods such as the Point Intercept method, which is time consuming, or some sort of subjective visual estimation, which is faster but less accurate. However, both these methods are sensitive to different observers and/or to different inventories. This paper addresses the further development and evaluation of a photographical inventory method that uses colour distribution in images to estimate lichen biomass. During the autumn of 2011 six different locations, with different grazing pressure and lichen cover, in Norrbotten county were inventoried using both the Point Intercept method and the photographical method, complemented with collection of biomass samples.

Studies show that activity based costing (ABC) is not widespread in practice even though it has been present in the academic world since the 80's. This thesis examines the reasons for the discrepancy between theory and practice through a case study of a Swedish manufacturing company. The intension is to answer the question of what contributes to the choice of precision in product costing.We found arguments for increasing precision in product costing but not to the extent of a full-scale ABC implementation. The company's estimation of the value of increased precision. In the study three company unique factors were isolated that affected the company's estimation of value; drifting purpose of product costing, historical use of product costing and knowledge about product costing..

The aim with this thesis is to investigate the risk management at the department Road construction, The National Road Administration Region Mälardalen. The aim is also to study how the risk management could be improved to better support the project leaders. Included in theses aims is to examine potential problems with the current risk management and to suggest changes. It is of utter importance to define the concept of risk, to study how risk can be measured and in which ways risk can be analyzed. In doing so, a literary study has be done and fourteen respondents has been interviewed.Risk is to be seen more as a concept than a quantity.

Sweden have 419 000 km road in the country and about half of these roads is forestroads. The forest road net most important mission is to make it possible to deliver wood from the forest to the industries. With a raw material that is spread over a large area the road network is important. Each year has the forest road network been extended with about 1 700 km new roads. To decide if a new road is to be built different forest road cost estimation models has been used.

The purpose of the thesis has been to explore the use of hedge fund styles when constructing portfolios of hedge funds (i.e. funds of hedge funds). The central question is if the use of hedge fund styles can significantly explain and improve risk adjusted returns (characterized by Sharpe ratios). The study has been done in collaboration with Optimized Portfolio Management AB who desire further knowledge and evaluation of hedge fund styles for their fund of hedge funds.To be able to create successful ex ante portfolios we have explored various prediction models for both risk and return. Our findings indicate that return prediction is problematic using simple models such as regression since the risk exposure of the indices appear to change significantly over time.

When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.

The purpose of this paper has been to find out what motives buyers of forest property has for there purchasse, what competence they have in economics and forestry, and what analysis they had done before the purchase. The study is based on interviews with nine different buyers from two geographical areas, five from Hälsingland and four from Småland/Skåne. A forest property is a property where the value to 100 % consist of forest. A part from the interviews every purhase has been analysed in comparison to an estimation of the yield value. The theoretical yield value was estimated with a computer programme.

ABSTRACTBackground: On behalf of the Orthopedic clinic, Västerås, a study has been conducted with focus on comparing the results after conservative and surgical treatment due to complete achillestendon rupture.Aim: To compare results when testing the active and passive range of motion, calf muscle endurance, estimation of pain related to the achillestendon and self-efficacy to be physically active for individuals who have undergone conservative or surgical treatment after complete achillestendon rupture.Method: 14 individuals afflicted by complete achillestendon rupture in 2010 were recruited as a purposive sample. Examination were conducted of: Ankle range of motion with a goniometer, calf muscle endurance through a toe-raise test, estimation of pain intensity related to the achillestendon by VAS and self-efficacy to be physically active through ?Exercise self-efficacy scale?. P-value and the median were calculated.Result: The results of ankle range of motion and calf muscle endurance were based on the difference between the injured and the healthy side. When testing active plantarflexion the conservative group had a median of 4 ? and the surgical group had a median of 10 ?.

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

Syftet med denna uppsats är att undersöka uppfattningar om risk inom mödrahälsovården. Den behandlar hur barnmorskor och deras patienter uppfattar risk i samband med och runt en graviditet och hur de hanterar denna. En av metoderna för att hantera risk är fosterdiagnostik, vilket syftar till att finna riskgraviditeter. Fokus har främst varit på barnmorskor med frågeställningar kring hur de informerar om risk och fosterdiagnostik, hur de ger råd och hur de uppfattar den inverkan detta har på deras patienter och hur dessa reagerar..

In this essay, Risk and crisis management Conservation policy and normalization production, I discuss how societies, communities and individuals are responsible for the handling of catastrophes and crises. Risk and vulnerability analyzes are parts of modern risk and crisis management. The purpose of these analyzes is to prepare people and organizations for any crises. For managing this it is necessary to comprehend, be able to change mindset in creating concrete tasks and inform others.The purpose of this essay is to analyze modern risk and crisis management by studying empirical material, such as interviews, observations and literature. My aim is to combine these materials and study how they cooperate.One of the findings in this essay is that risk and vulnerability analyzes are of great complexity. These analyzes require a discussion in order to identify the development of the society's crisis management system, as well as the continued support of the individuals that have a responsibility for preventing and preparing their organizations..
