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.

The aim of this project was to develop educational resources concerning bioenergy and sustainability. The initial purpose was to produce two sets of material: one suitable for children in their first years of Swedish compulsory school, and one designed for upper secondary students. In the report, however, the possibilities are discussed for this material to be used with even wider audiences.In the first phase of the process, literature (books, reports etc.) with relevance to bioenergy, sustainability and theories of learning were studied. This insight, along with the appropriate course curriculums, was used in the development stage to produce learning material for the targeted audiences. The development was followed by tests and evaluations carried out with high school students, upon which an analytical discussion is held regarding the consequences and possibilities that the results of this project pose.The content of the learning material is based on the curriculum and course requirements provided by Skolverket (The Swedish National Agency for Education) for lower elementary and high school students.

För företag som verkar på den dynamiska och konkurrenskraftiga modemarknaden är den storautmaningen att skapa en hållbar konkurrensfördel för att på ett lönsamt sätt vinna kampen omkunden. Ett viktigt verktyg är en effektiv och flexibel inköpsprocess. Utformningen avinköpsprocessen avgör förmågan att möta den krävande modekundens efterfrågan. Vår studie avseratt undersöka hur inköpsprocessen bör organiseras hos en produktutvecklande modedetaljist för attvara effektiv och kunna möta marknadens förändringar. För att påvisa ämnets praktiska relevans ochförtydliga problematiken används ett fallföretag där kvalitativa empiriska undersökningar har utförts.En inköpsprocess består av olika aktiviteter som tillsammans påverkar processens utfall.
