Renewable energy is gaining increasing importance in the generation of power due to the finite existence of fossil fuels and concerns about climate change. As its demand grows financial interest from investors’ increases, thus it is important to find the most effective way of quantifying the risk of the renewable energy market. Furthermore as renewable energy can be viewed as an economic substitut
In this paper we present two novel generic schemes for approximation algorithms for optimization NP-hard graph problems constrained to partial k-trees. Our first scheme yields deterministic polynomial-time algorithms achieving typically an approximation factor of k/log(1-is an element of)n, where k = polylog(n). The second scheme yields randomized polynomial-time algorithms achieving an approximat

Additiv tillverkning (AM) är vanligtvis relaterat till snabb prototypframställning, även om det nu för tiden blir ett verkligt alternativ för mindre serieproduktioner. Expansionen av denna teknik är direkt relaterad till produktionskostnaderna, men med rätt verktyg i designfasen är det möjligt att även hjälpa utvecklarna av en produkt att välja vilket som är det bästa materialet eller AM-tekniken Additive manufacturing (AM) is commonly related to rapid prototyping, although nowadays it is becoming a real option for small-batch production. The expansion of this technique is directly related with the production costs. However, with the supporting tool in the conceptual phase of design it is possible to guide the product developers at selecting the most appropriate material and AM technology
As a continuation of the work on the development of setting the requirements for ventilation of a bicycle helmet for commuters, 15 full scale helmet mock-ups were created by the students of the Estonian Academy of Arts. In order to encourage creativity for ventilation solutions the students were not restricted to consider the other properties except it was pointed out that the meaning of helmets u
Mellan åren 2015 och 2021 har lag om tillfälliga begränsningar av möjligheten att få uppehållstillstånd i Sverige varit gällande istället för utlänningslagen. Lagen infördes för att minska antalet asylsökanden och uppehållstillstånd i Sverige. Nu när den tillfälliga lagen slutar gälla har det kommit ett förslag på att permanent ändra utlänningslagen så att vissa bestämmelser är mer lika de som funIn 2015 the Swedish government wanted to reduce the amount of asylum seekers entering Sweden. This resulted in the temporary law, which tightened rules for immigrants. The temporary law expires on 19 July 2021 and therefore the government has decided to refer proposals to the Council on Legislation for amendments to the Aliens Act. According to the temporary law immigrants can only receive a tempo
Centralt för uppsatsen är Leo-lagen som tillkom efter en företagsskandal på 1980-talet där ledande befattningshavare i AB Leo fått teckna aktier i bolaget till fördelaktiga villkor. Leo-lagen som nu återfinns i 16 kap. ABL stadgar att ett beslut om nyemission måste fattas av bolagsstämman med minst nio tiondelars majoritet om de som ska ha rätt att teckna aktier ingår i den av Leo-lagen utpekade fIn the centre of this paper is the 16 chapter of the Swedish Companies Act (Sw. aktiebolagslag (2005:551) (ABL)). The law was adopted after a big company scandal in Sweden during the 1980s where officials in the company where given shares at profitable terms. To prevent this scandal from occurring again the law states that a decision to issue new shares to officials has to be made at the annual sh
Syftet med denna uppsats är att utreda den svenska faderskapspresumtionen, som innebär att en gift man automatiskt blir juridisk far till barn födda av hans maka. Detta görs utifrån ett barnrättsperspektiv, vilket innebär att regleringen studeras i relation till principen om barnets bästa så som den kommer till uttryck i svensk rätt och barnkonventionen. Ämnet är högaktuellt i dagens samhälle, där
Electric bikes have become ubiquitous in traffic, and with a growing user base and expensive prices, a demand for bike protection is increasing. Bike protection applications could include detecting and notifying the owner if their bike has been stolen or fallen over. This thesis aims to develop solutions for recognizing and classifying motion patterns of an electric bike to allow for improvements
Common transport models use the mixing height (MH) to determine turbulent coefficients and to obtain tracer concentrations in the planetary boundary layer (PBL). We conducted a pseudo data experiment to elucidate the impact of assimilating MHs to improve CO2 transport within the Stochastic Time-Inverted Lagrangian Transport model (STILT). Transport of CO2 was simulated for August 2006 with a recep
BACKGROUND: Oesophageal cancer management requires extensive in-hospital care. This cohort study aimed to quantify in-hospital care for patients with oesophageal cancer in relation to intended treatment, and to analyse factors associated with risk of spending a large proportion of survival time in hospital. METHODS: All patients with oesophageal cancer in three nationwide registers over a 10-year
In the field of dendrochronology, scientists work with the process of ordering different trees in time by using their annual tree ring width (TRW). The TRW data are logged in time series and cross-dated with each other to find out in which period of time they both were alive. The two TRW series are then conjoined by taking the average of their ring widths in each overlapping year, and this can be
