Uppföljning av planerat skotningsavstånd med hjälp av geografisk informationsteknologi (GIT)
The cost of forwarding corresponds to about one tenth of the forestry industries raw material cost. This gives a motive to do good follow-ups to get a good overview of the forwarding distance and, thus, enable improvements. Follow-ups are also justified by the possibility to make more accurate calculations of the harvesting costs, if better estimations of forwarding distance are achieved. Today (2009) Stora Enso has GPS and vehicle-computers in most of their forwarders. These are used mainly for the forwarder to follow the tracks of the harvester and for the planning leader to see how the forwarder has been driving within the stand.
Perspektiv på avreglering av svensk järnvägspersontrafik
This thesis examines the deregulation reform of the Swedish railroad industry, focusing on passenger transport between 1988 and 2005. The purpose of the thesis is to examine the effects from the deregulation reform on prices, market concentration and to determine whether SJ (the state owned incumbent) has been conducting strategic behaviour in order to prevent new entrants to the market. The chosen method consists of interviews with the MD at SJ between 1988 - 1998 Mr Karl-Erik Strand, the transportation researcher at SSE Mr Gunnar Alexandersson. Statistical sources and companies financial reports have also been used. The results that I have found were besides the fact that the market concentration is still significant high and the profitability among the operators low, is that the prices has increased more than CPI during the period but the competitive tendering has resulted in lower government subsidies after the deregulation.
Fildelning : Avvägningen mellan upphovsrätt och integritetsskydd
The relation between copyright and the right to privacy is complex and difficulties exist in balancing the rights. Copyright should not be limited. Therefore, to ensure the economic rights of the copyright owners, must the right to privacy instead be limited whenever the two rights collide.The implementation of IPRED into Swedish Law meant a vast change as private operators are able to request information concerning a suspected infringer before as well as during a proceeding concerning an infringement of intellectual property. The chosen implementation method goes beyond IPRED?s requirements and also sanctions a lower standard of proof to grant the requested information.
Förvärv och försäljning av fastighet med förorenad mark : Särskilt gällande ansvar och friskrivningsklausuler
Properties are bought and sold daily, which means that it is of great importance with rules that regulate the acquisition. The rules on who should be held liable for a property brought to a head when the acquisition relates to a property that is loaded with contaminated soil. The purpose with this thesis is to investigate who could be held liable for contaminated land and also whether an exclusion clause can affect the separation of responsibilities. Two different liabilities can occur depending on which law that should be applicable, MB or JB.MB's rules apply to anyone who may be subject to decontamination responsibilities, which is regulated in Chapter 10.

Marknanden för professionell golf : en institutionell analys av Europatouren för herrar
Studiens första syfte är att med institutionell teori kartlägga det kontraktsnät som konstituerar den europeiska marknaden för professionella herrgolfare. Det andra syftet är att analysera och diskutera vissa utvalda aspekter av detta kontraktsnät som utmärker Europatouren från traditionella vinstmaximerande företag. Den europeiska marknaden för proffsgolfare har organiserats i ett företag för att det är ekonomiskt fördelaktigt. Med Europatouren som en sammanhållande länk begränsas transaktionskostnaderna bl.a. genom att antalet kontraktsvägar reduceras och genom att utrymme för långsiktiga relationer med viktiga parter skapas.
Frekvensreglering i det nordiska kraftsystemet
Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.
Analys av spänningsstabilitetsberäkningar i det svenska elsystemet
Numerical simulations play a vital role in both static and dynamic stability assessment of electric power systems and the foreseeing of voltage collapse. Simulations performed by Svenska Kraftnät(SvK) are mainly done in the specialized voltage collapse predicting software tool, SPICA and the more all?purpose software tool, ARISTO.The grid operators at SvK use SPICA to predict the maximum transfer limit at specified sections (in this report the section in concerns is the southern part of Sweden i.e. interface1 4). SPICA is mainly used as an online application by using actual states from the grid, these states update every quarter of an hour.This thesis is a continuation of the master thesis SPICA ? ARISTO JÄMFÖRELSE by Jakob Katzman and Johan Fält.
Risken för översvämningar vid de svenska kärnkraftverken : en statistisk och historisk extremvärdesanalys
This thesis investigates the overall risks of flooding over the Design Basis Flooding Level (DBFL) at the Swedish nuclear power plants (Oskarshamn, Ringhals and Forsmark), using statistical data and methods, but also considers historical events which might affect the overall risk of flooding at the specified sites.Considering the nuclear accident which happened in Fukushima in conjuction with the earthquake and tsunami which struck eastern Japan on 11 March 2011, operators and licensors of nuclear power plants all over the world conducted reviews and investigations on the overall risks posed to the plants from external events. One important such event is extreme water level.One part of the thesis includes an extreme value analysis (using Generalized Extreme Value distribution and Generalized Pareto distribution) of water level data from SMHI (Sweden's Meteorological and Hydrological Institute) measured at stations close to the Swedish nuclear power plants. The results of the statistical studies indicate that considering the return period used in the thesis (100 000 years), the water levels at the Swedish nuclear power plants are not expected to exceed DBFL.The other part of the thesis consists of a historical study of extreme weather-related events. The results of this study indicate that no historical events seem to have occured which would indicate a higher risk of flooding than the one suggested by the statistical study. .
