We present a comparison of different univariate and multivariate extreme value risk models. Our focus is on exploring how these can be used to model financial risk. We use simulated as well as real data and compare deterministic and cross-validation threshold selection methods for the GP model to a GEV model. For comparison, we carry out a bivariate analysis using copulas. Finally, an undirected g

Today, digital circuits are part of every ones daily life in form of mobile phones, computers, television, smart cards etc. The advent of new technologies such as internet of things, 5G etc. are continuously making the digital circuits more and more complex in design. With this increase in complexity comes the possibility of more bugs in the system. Finding and fixing these bugs is of paramount im

The building industry consumes approximately 40 per cent of materials entering the global economy while facing significant challenges related to unsustainable consumption of natural resources and greenhouse gas emissions. The concept of the circular economy is gaining momentum as a solution which addresses these issues while generating economic benefits. To transition towards a circular economy, s

The fashion industry has always been a synonym of new trends, creativity, design and a form of expression and individuality. Notwithstanding, the impact on the environment and the development of societies derived from the production and consumption of fashion has been underestimated. The current system is extremely polluting and wasteful, and it is closely related to poverty, gender issues and exp

This paper analyses the economic impact of Transnational Corporations through their activities across Global Value Chains (GVCs), using Mexico as baseline country. By exploiting the UNCTAD-Eora Global Value Chain database, we conduct an exploratory research methodology. We first unfold the relationship between GVC trade and economic development by disaggregating GVC trade into its two components (

The purpose of this study was to investigate why women are highly underrepresented within the field of physics around the world. The study was mainly conducted through qualitative interviews with adolescent girls and it aimed to shelter more than just a local perspective; therefor the interviews were performed in three different schools, in three different countries; one in Bukoba, Tanzania, one

The purpose of this essay is to examine how the Catalan independent movement has evolved through the centuries with modernistic thoughts of Nationalism from the 19th century to current day. The essay uses three main methodological tools such as Source criticism, Periodization and Contextualization to get an all-rounded understanding of Catalonia’s history. To fully understand Catalonia’s independe

This thesis investigates the role of marijuana use in labor productivity in the United States with the aim to contribute to the discussion and understanding of economic consequences of marijuana legalization. The data is sourced from various federal agencies to create a panel of 50 U.S. states and the District of Columbia for the period of 2005-2017. A panel data model with fixed effects is estima

Den utbredda gängkriminaliteten och bruket av vapen eller andra farliga föremål på offentliga platser är ständigt närvarande i den politiska debatten i Sverige. Frågor rörande vilka medel och befogenheter polisen har och bör ha återkommer frekvent och i diskussionen framkommer ofta referenser till Danmark och systemet med visitationszoner som där finns. En liknande, men inte identisk, lagstiftningThe widespread gang violence and the use of weapons in public spaces are often focal points in Swedish political debate. Questions regarding which means and authorities the police have and should have are raised frequently and references to Denmark and their system with ‘stop and search’ zones are often mentioned in the discussions. A similar, but not identical, legislation to the one in Denmark h

Background The widespread antibiotic resistance is an imminent problem in today’s world. As the number of antibiotic resistance cases increase, it is inevitable to discover alternate treatment options. Probiotics could be one of the potentially important avenues which could be exploited to treat antibiotic resistance and other infections. The holistic approach of probiotics in exerting their benef

As transistors in integrated circuits (ICs) are becoming smaller, faster and more, it has become harder to avoid malfunctioning. Embedded instruments are increasingly used to test, tune, and configure the transistors in ICs. IEEE Std.1149.1-2013 and IEEE Std.1687 standardize the access to these embedded instruments. IEEE Std.1687 enables reconfigurable scan networks which allow only desirable inst

Community resilience is a highly relevant topic and the focus of much contemporary research, however it has yet to be distilled down to an exact science. The current thesis applies a theoretical framework for community resilience as an analytical lens when investigating the community response to the Grenfell fire and tragedy of 14th June 2017. Of particular interest is to uncover what community re

This paper aimed to identify discourses and interpretative repertoires, used by the CIA to construct a narrative regarding terrorism when communicating with the public. This was done by analysing texts found on the official CIA website with discursive psychology methodology. Three main themes were identified, with thirteen subthemes. These related to how the CIA presented terrorists, terrorism, an

Idag finns mängder av kommersiella VST-syntar som modellerar klassiska analoga syntar men det finns lite publik forskning på området. Anledningen till att det är av intresse att efterlikna klassiska analoga syntar är att deras oscillatorers grundvågformer sällan är perfekta. Denna imperfektion ger anledning att undersöka och digitalt implementera klassiska analoga syntar för att ta reda på vad det

The role of private cars in urban areas is coming under increasing scrutiny. A growing number of municipalities are now implementing or exploring the potential of car-free city centres (CFCCs), defined zones in which car use is prohibited or severely restricted. Whilst CFCCs can deliver environmental, social and economic benefits for cities, businesses are routinely opposed to the introduction of

The demand for space cooling is rising. The increase in cooling demand can put significant strain on the electric grid since approximately 99% of air-conditioning and refrigeration loads worldwide are met with electricity. Many hot weather cities could benefit from district cooling (DC) systems to meet their growing cooling demand in an effective sustainable manner. Since these systems require sig

Insects play vital roles in almost every ecosystem and have high ecological, social as well as economic value. Human activity -most critical in urban environments- profoundly stress insect populations and habitats, regardless of their known benefits to society. Conserving insects in an urban context remains a topic predominantly for insect enthusiasts and revolves around preferred insects, such as

As a result of the current climate crisis, which reflects people's unsustainable consumer behaviour, there is an increased need for companies to apply sustainability strategies. One of the responses to the crisis is the increasing number of packaging-free grocery stores that have opened across Europe. These new stores have the intent of reducing waste by using, for instance, Circular Economy s
