Wind damages next to strip roads in 1st and 2nd thinning in Boxholm, Östergötland Anneli Fransson, SLU, inst f sydsvensk skogsvetenskap, Examensarbete no 108 Wind damage is something we are all familiar with since the storms Gudrun (2005) and Per (2007). Research about strip roads and wind damage is very limited. It is commonly known that the trees next to the strip roads more often fall whit heavy winds, and the purpose of this thesis was to verify this statement. Data was collected from first- and second thinnings at Boxholms Skogar AB, Östergötland. In first thinnings data was collected from both spruce and pine stands and second thinnings only data from spruce stands was collected.

This study was performed in collaboration with Moelven Skog AB, Örebro district. The purpose of the study was to review existing literature in order to describe the current status of harvester based measurement technology as the way to provide information for calculating payment to the forest owners. In addition to this, a short survey was conducted to find out how a switch to harvester based measurement would affect the administrative workload on timber purchasers working for the district. The literature study shows that the harvester measurement technology is ready to use if it is combined with well-established routines for control of the harvesters, methods for automatic quality indexing of the timber and ways of creating pricelists specially adapted for harvester measurement. Pricing each stem seems to be the most promising method. Stem pricing has several benefits.

Chapter 1 defines the aim of the project and gives a general orientation about ground heat extractors. In chapter 2 physical processes that could be expected to be involved in the heat transport around a ground heat exchanger are discussed. It is shown from a literature study what amount of moisture transport due to thermal gradients there could be expected in a ground heat exchanger. The conclusion is drawn that the moisture gradient (Sr) is of same magnitude as the driving temperature gradient (°C). At the expected amount of increased moisture around the pipes the moisture transport could be considered to have a little effect on the brine temperature.

During the last two decades, technology has developed rapidly. It has become a natural part of everyday life, which we today take for granted. It isn?t until the last few years that technology has quickly become a big part in the school environments. Computers, tablets and other technology is today a big part of the education and teaching.

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.

Hästar har transporterats längre sträckor i århundraden, först med båt och tåg och därefter på väg och med flyg. Antalet hästar som transporteras på väg har ökat i takt med att antalet hästtävlingar har ökat. Syftet med denna litteraturstudie var att ta reda på vad som kan göras för att förhindra och åtgärda de störningar som kan uppkomma i vätske- och saltbalansen i samband med transport genom bland annat utfodring och bra rutiner. I studien ingår även en presentation av gällande regler för transport av häst. Hur hästen ska transporteras är reglerat i djurskyddslagen (SJVFS 2000:133). Transporttiden får högst vara åtta timmar därefter måste hästen vila.

Holmen Skog is one of the largest forestry companies in Scandinavia and they depend heavily on a large network of forest roads for production and logistics in connection to their forestry operations. The company recently introduced a new system for planning of road management. The system will also be developed with the intention to facilitate the monitoring of actions performed by road contractors. This report will provide information to support future decisions regarding further development of the system, after its introduction. In addition to a presentation of results from interviews, the report also provides a smaller study of the different subjects associated with roads, process work and process development. The study is largely based on interviews with road contractors that perform work for Holmen Skog today.

In Sweden, there an increasing need for transport and this leads directly to fuel demand of the transport sector is expected to increase. Both politicians and industry believes that renewable fuels are a realistic and significant method to reduce the transport sector's environmental impact. This study aims to document the Swedish haulage contractor?s attitude to biodiesel. Also to document the strengths and weaknesses of biodiesel, based on opinions from the ultimate consumers.

In published studies it is found that the fuel consumption on a forwarder is relatively constant, on time basis. A certain variation between different sizes of forwarders occurs as well as between different working elements. The aim of the study was to establish a forwarders comparatively fuel consumption when driving on road and in the terrain, loaded and unloaded, with high and low gear and with high and low speed as well as with hydrostatic and hydrodynamic transmission. A hypothesis was that low rpm gives lower fuel consumption on distance basic, at all trials. The test driving was made with a Hemek 750 which is a three geared hydrostatic machine and with a Hemek 700 which is a hydrodynamic machine with six gears.

In this report we examine the NFC (Near Field Communication) technology as far as the development has come until today. We adress different use areas and explain the technical funcionality. By using data collection methods as a specialist interview and also a survery we want to detect potential risks and safety-issues in implementation of the new technology. Our main-focus in this report is to examine how NFC can play an important role in the developement of social interaction and social media. By compiling our data and research materials we will analyze and present a report conslusion.

As the use of smartphones and other mobile technology in our society is constantly increasing,so too does the possibilities of visually impaired persons increase as they are becoming moreable to enhance their quality of life with the help of mobile assistive technology. The purposeof this study was to explore how rehabilitation and habilitation organizations, which areworking with the visually impaired, should approach new technology. We have researched thisby examining the possibilities, opportunities and barriers of using mobile assistive technology.Based on this, we formulated the following research question: What factors are important forrehabilitation and habilitation organizations to consider in order to support, promote andcreate quality of life through the use of mobile assistive technology in their work with thevisually impaired? To answer the above question an exploratory study was made at an eyeclinic in the Västra Götaland region. The study was done through a series of qualitativeinterviews with both staff and patients at the eye clinic.

The Swedish Transport Agency has for a long time collected data on a monthly basis for different variables that are used to make predictions, short projections as well as longer projections. They have used SAS for producing statistical models in air transport. The model with the largest value of coefficient of determination is the method that has been used for a long time. The Swedish Transport Agency felt it was time for an evaluation of their models and methods of how projections is estimated, they would also explore the possibilities to use different, completely new models for forecasting air travel. This Bachelor thesis examines how the Holt-Winters method does compare with SARIMA, error terms such as RMSE, MAPE, R2, AIC and BIC  will be compared between the methods. The results which have been produced showing that there may be a risk that the Holt-Winters models adepts a bit too well in a few variables in which Holt-Winters method has been adapted.

Augmented reality is an interesting technology which has increased in popularity the last couple of years. Even though we see more and more of this technology the use of it doesn?t match up to its true potential. This paper aims to investigate the possibilities of this technology and illustrate how companies can use it in their business to reach out to customers in a new and exciting way. The study consists of three parts.

The aim of this present study was to determine and evaluate whether the presence of brooktrout (Salvelinus fontinalis) and sediment load may be a threat against the reproduction anddistribution of freshwater pearl mussel (Margaritifera margaritifera) in a creek located innorthern Sweden. Freshwater pearl mussel is an endangered species and is dependent ofbrown trout (Salmo trutta) to reproduce. Therefore there are concerns of indirect effects onthe population of pearl mussel by competition between brown trout and brook trout. Ditchesfrom a nearby gravel road have been fixed to lower the sediment load into the creek. I tried toevaluate this action plan.
