Köp av skogsfastighet : en fallstudie
The price of Swedish forest properties has gone up by 77 percent during the past five years. Amongst private forest managers the high price level signals optimism and confidence for the future.
Many forest owners manage large capital in the forest and a planned economy is to a larger extent demanded to achieve a positive economic result. Forest is long-term and to maximize a single year without planning for the years to come results in less optimization of the parameters available to achieve a favourable economic result.
This case study investigates the investment of two forest properties situated in Götaland.
The management of the forest has been planned for both properties during a period of ten years.

Kulturellt och psykiskt avstånd : En studie om EU:s inre marknad
Objective: The papers objective is to create a deeper understanding for whether or not cultural and psychic distance affects corporate establishments in the EU.Method: The results have been gathered through intense data collection through interviews with ScaniaAB and Business Sweden. There has also been extensive research of 36 different companies and their first establishments in different countries. We have then analyzed the results through cultural and psychic distance and through Uppsala University's internationalization process model.Conclusion: The conclusions of this paper are:Corporate establishment often occurs in neighboring countries because of the similarity to the domestic markets which contribute with a greater security.Since the introduction of the EU single market, corporate establishments have become easier within the single market.The cultural and psychic distance does exist within the EU, however the internal market decreases these distances and the impact on corporate establishments.The market commitment is essential to the corporates survival within the new market.Cultural and psychic distance affects small firms more often since their lack of network and experience.Cultural and psychic distances are two different but related phenomena..
Hur svårt ska det vara egentligen? : Om problematiken att fastställa gränsvärden för energiåtgången i klimatsmarta byggnader i Sverige
EU-kommissionen har beslutat att Europas byggnadsbestånds energianvändning ska minimeras. Varje medlemsland har fått i uppdrag att definiera ett nationellt gränsvärde för vad som ska kallas för nära-nollenergibyggnader och gränsvärdessättningen skall vara klar år 2020. Myndigheterna Boverket och Energimyndigheten samt andra involverade aktörer är inte överens om vilken gränssättning som ska gälla för Sverige. Syftet för studien var därmed att undersöka vad dessa motsättningar beror på. Genom ett kvalitativt tillvägagångssätt, där offentliga handlingar kring beslutsprocessen studerades, identifierades de involverade aktörer och deras egenskaper genom en nätverksteoretisk grund.
Voltage Sags Indices and Statistics
Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

Lärares gemensamma lärande : En kvalitativ intervjustudie av lärares uppfattningar kring samverkan och en gemensam handlingsarena
Studien ?Lärares gemensamma lärande - En kvalitativ intervjustudie av lärares uppfattningar kring samverkan och en gemensam handlingsarena? har syftet att öka kunskapen om betydelsen av lärares möjligheter till att se varandra i handling och ämnar besvara följande frågeställningar; Hur formas, upprätthålls och utvecklas samverkan mellan lärare?, Vilken betydelse utgör en gemensam handlingsarena för lärares samverkansstrategier? Den här studien utgår från teorin om det kollektiva lärandet. Denna teori innehåller tre typer av samtal; berättandet, det gemensamma reflekterandet och det gemensamma intentionsskapandet, som i denna studie ses som villkor för att nå upp till ett kollektivt lärande. Teorin har vidareutvecklats genom ett införande av begreppen ?nätverk? och ?gemensam handlingsarena? som för den här rapporten eventuellt kan ses som ett fjärde villkor för ett kollektivt lärande.
Beslutsstöd för lagerhantering : Matematisk optimeringsmodell för godsplanering och simulering
Det är allt vanligare inom tredjepartslogistik att kunder hyr en yta för lagring. För den uthyrande parten, i detta fall Delta Terminal, är arean den begränsande faktorn för hur stor yta som kan hyras ut. Idag använ-der sig Delta Terminal av beslutsunderlag i form av lokalernas area och erfarenhet vart gods ska placeras och har inget hjälpmedel för att beräkna vart och hur mycket gods som kan allokeras för att använda så liten yta som möjligt. Studiens syfte har därför varit att ta fram ett faktabaserat hjälpmedel som kan användas som beslutsunderlag. För att uppnå syftet har en matematisk modell utvecklats för att optimera hur gods kan placeras till olika lokaler för att använda så liten area som möjligt och även kunna simulera förändringar.
Profitability and competitiveness of grain handling at farm level
The Swedish agricultural sector is currently experiencing substantial structural changes, where the number of agricultural enterprises continuously decreases and the average farm size increases. In order to maintain competitiveness, it is important to be aware and adapt to changes concerning the surroundings of the company (Johnson et al., 2011). Agricultural commodity prices sharply fluctuate on the global market in recent years, affecting the profitability of farmers. High volatility market requires tools to reduce price variations and increases the need of decision-making (Bouder & Beth, 2003). Farm-based grain handling facilities increases the sale options regarding agricultural commodities; a flexible strategy to get additional compensation for the storing the grain produced on the farm (Edling, 2002; Edwards, 2013).
