K¨anslighetsanalys av barri¨aroptioner med algoritmisk derivering F¨or att f˚a ut optionspris och derivator p˚a priset med avseende p˚a tex r¨anta och volatilitet, utf¨ors vanligtvis ett antal simuleringar varp˚a ett medelv¨arde r¨aknas ut. D¨arefter r¨aknas derivatorna ut med en finit differensmetod. F¨or att erh˚alla tillf¨orlitliga resultat med denna metod kr¨avs ett stort antal simuleringar viAutomatic Differentiation (AD) is an effective method for calculation of derivatives. It can evaluate an unlimited number of derivatives to a fixed cost relative to the computing time of the original function. The AD technique is used in many fields for large and complex calculations in order to get accurate values of derivatives fast. Banks and other financial institutions handle calculations of

The universalistic understanding of the subject embedded in the Liberal and Marxist traditions together with contrasting accounts of unconstrained agency fail to explain the contingencies of ground responses that call for social change. The paper makes a case for the opening of the understanding of the human subject when placed in the theoretical terrain of radical political philosophy elaborated

Ground deformation monitoring is one of the main geoindicators that should be considered to assess volcanic hazard. Satellite earth observation data and Synthetic Aperture Radar (SAR) interferometry have been used continuously since 1992 to measure or study the temporal evolution of surface deformation in volcanic areas in conjunction with ground-based geodetic measurements. Such methods were app

This study explores the contexts in which the conflict evolved and how history was perceived, narrated and used by institutions, communities and individuals who sought to influence public opinion and policymakers. The theoretical point of departure is the concept of collective memory, defined as the totality of discourses through which a society makes sense of itself, the present and the future th

In this thesis we consider different tests for unit roots in the presence of structural change. We present the theory that lies behind unit roots, what we mean by structural change and try to detect the instances that “breaks” occur in the data. When performing a unit root test, when there is a structural change the results are biased toward accepting a unit root. Therefore, special care must be t

Användandet av fjärranalysdata är en viktig metod för att bestämma markanvändning och visa på förändringar i marktäcke. Fjärranalys kan ge en bättre utgångspunkt för övervakning av markytstäcke. Det gör det möjligt att geografiskt lokalisera förändrade markområden för att vidare kunna utföra noggrannare undersökningar om miljöförändringar (t.ex. markdegradering). Studieområdet är ett administrativThe use of remotely sensed data is an important method to indicate land use and land cover changes. Remote sensing can provide a better picture of monitoring land use and land cover changes. It makes it feasible to locate geographically changed areas in order to employ it further detailed studies on environmental changes (e.g. land degradation). The study area is a heterogeneous and small-structur

The main purpose of this research is to contribute to sustainable waste management in remote areas of the European Union (EU) by specifically employing the concept of ‘waste hierarchy’ as a mean to reach this goal. The last three decades see the EU waste management approach evolve from pollution control (disposal/end-of-pipe) toward more strategic approach focusing on waste prevention and recyclin

In line with cognitive semiotics, this paper suggests a synthetic account of the important but controversial notion of narrative (in street art, and more generally): one that distinguishes between three levels: (a) narration, (b) underlying story, and (c) frame-setting. The narrative potential of street art has not yet been considerably studied in order to offer insights into how underlying storie

The article begins from critical accounts addressing the crisis of politics and citizenship today, to study the civic potential that several media and social scholars view in informal practices that include the usage of new media and information and communication technologies. On one hand, new media and ICT are noted to empower individual users and groups, to provide spaces of voice and debate and

A study of past lake-level changes in Lake Xinias covering the last 40 000 years was presented in an earlier paper. In that paper.. changes during the Holocene were only briefly dealt with. because of poor sedimentary representation. In this paper a Supplementary transect of cores is described, in which Holocene lake-level changes are better recorded. The correlation of the cores was based on poll

Over the last decade, the unprecedented influx of refugees and migrants into the European Union has posed a significant challenge to Europe, with solidarity being contested at two fronts: first, the question of solidarity with refugees in terms of meeting adequate measures of protection and satisfying their elementary needs; and second, the question of solidarity within the European Union in terms

Wildfire evacuation is a life-saving measure of last resort, but delays can lead to dire outcomes, putting people at risk of fire entrapment. The success or failure of an evacuation depends on the relative speeds of the wildfire and the evacuation, and this varies across communities and wildfires. Despite the importance of understanding this dynamic, no formal framework exists to define or quantif
