Den odränerade skjuvhållfastheten är en viktig geoteknisk parameter som man behöver ha en god uppfattning om i samband med byggnation på lerrika jordarter. Då flertalet av de vanligen tillämpade undersökningsmetoderna är väldigt tidskrävande och kostsamma, finns det ett stort intresse för att undersöka hur alternativa och samtidigt mer enkelt mätbara parametrar, så som flytindex (IL), förhåller siUndrained shear strength is a crucial parameter of the clay-rich sediments commonly used in the design process of geotechnical structures and is determined by several tests. As a considerable part of these tests are cost- and time consuming, it is of interest to investigate the potential relationship with shear strength (cu) with alternative, easily measurable parameters, such as liquidity index (

Electromechanical oscillations is a power system phenomenon where generator rotors oscillate, leading to oscillatory power flows. Damping of such oscillations is important for system stability. Forced oscillations is a special case where one faulty component is the source of the oscillation. This report concerns the Dissipating Energy Flow (DEF), which is an energy-based method for analysing dampi

The purpose of this thesis was to explore how a newly founded Youth Platform in Colombia, called La Mesa de Juventud, could affect the youth community in promoting and capacitating organizational skills, youth citizenship rights and youth influence in public policy making. The study emanates from the region of northern Cauca situated in the South Western part of Colombia which is an area where you

The purpose of this thesis was to determine how a heavy duty vehicle manufacturer can create an economical viable business model for used batteries from electric buses and trucks. Heavy duty vehicles are responsible for 30% of on-road CO2 emissions in the European Union, but could be decreased if this sector would be electrified. One major barrier for this transition is the large cost for the batt

This thesis explores the extent to which international human rights law and international labour law place obligations on States to protect migrant workers’ fundamental rights, especially their rights to social security. More importantly, this thesis examines intra-ASEAN migrant workers’ accesses to the social security benefits, as defined by the ILO Social Security (Minimum Standards) Convention,

Simulating the natural environment of living tissue with in vitro cell culture models has paved the way for scientific discoveries, and provided valuable insight into areas such as drug discovery and regenerative medicine. A new emerging technique of culturing cells on biomimetic three-dimensional scaffolds stands as a promising alternative to the traditional way of culturing cells on two-dimensio

For every stock investor, the question of how many stocks to buy is fundamental. The recommendations from the literature is wide and ranges from 10 to over 300. As a contrast, 41.79% of Swedish shareholders held only one stock in year 2020. This thesis studies the Swedish stock market between 2011 and 2020 which to the authors knowledge not has been done before within the research space of Diversi

The primary purpose of this paper is to further build on research related to capability development in order to explore hindrances and benefits of internal capability development and external partnerships as ways to improve performance. The beverage industry is used as the focus context since the companies in this industry are increasingly responding to external trends and looking for ways to deve

Meal-kit boxes are considered a solution to reduce greenhouse gas emissions by reducing the food waste in the supply chain and households. Nevertheless, the consumers are concerned about the amount of packaging that comes with such a box, which is connected to higher carbon emissions than a grocery store meal. Thus, HelloFresh, a global market-leader in meal-kit boxes is driven to find more sustai

Travel today is not as self-evident as it has been the last few decades. This paper takes on a mission to investigate how external factors such as natural disasters, geopolitical tensions, and above all; epidemics, call for an external crisis communication for travel and tourism companies.

Climate change and human impact play a huge role in the sustainability and development of ecosystems and the services they offer to societies over temporal and spatial scales. Fossil pollen-based estimates provide unique information on past land cover change, but to date there are not many methods able to create spatially continuous maps and have a fine scale of land cover changes inferred from po

People's preferences for income inequality vary, and this research investigates the influence of socioeconomic status on these preferences. Drawing on a structural position theory that considers individuals’ self-interest and rationality to be driven by their socioeconomic status, this paper examines the extent to which socioeconomic status affects the likelihood of accepting income inequality

In this thesis I study international space law’s rules on international responsibility and international liability for private satellite launches. I have used a legal dogmatic method to interpret these rules, before subjecting them to an economic analysis on how they will affect the behaviour of private actors and States. Finally I propose solutions to increase the economic efficiency of three dif

In this thesis the effects of utilizing the sample covariance matrix in the estimation of the global minimum variance (GMV) portfolio are presented. When the number of assets, N, are close to the number of observations, T, the sample covariance matrix approaches singularity, leading to a lot of uncertainties in form of estimation error. Due to that the computations of the sample GMV portfolio are

Sustainability Science (SS) is known for aspiration to support societies towards ecologically sound trajectories – a fabulously reflexive, ultimately critical and deeply self-aware field with a diverse community of highly skilled and creative researchers of noble goals, rigorous training and active engagement with ‘real life’ (so we claim, or at least aspire for). We try hard to alter extinction o

It is well-known that long memory and regime switching in the first moment of a stochastic process are easily confused. But the relation between long memory in the second moment and regime switching in the second moment is less well understood. We perform a simulation study in which we assess the possibility to distinguish the two properties in the case that data with long memory in the second mom

This thesis addresses the highly topical subject of global income inequality within the developed economies. A constructive analysis approach inspired by Swedish political scientists Bo Rothstein, Lennart Lundquist and Björn Badersten is employed analyze the economics blockbuster Capital in the Twenty-First Century by French economist Thomas Piketty. Empirical, normative and constructive theories
