Undersökning av hur penetrationstalet i bitumen påverkar styvheten av cementstabiliserad asfalt i laboratoriepackade prover

A semi-flexible pavement is a composite material consisting of an open-graded asphalt skeleton with an air void content between 25 - 35% that is filled with a cement sludge. Limited research has been done regarding factors which can affect the mechanical properties of this material. Therefore, this study explores the affect the penetration value of a bitumen has on the stiffness of a semi-flexible

One slope does not fit all: Investigating Heterogeneity in Cointegration and Panel Methods in the Energy Intensity Literature

This thesis aims to analyze the methods of existing studies on the relationship be- tween energy intensity and economic variables. I study panel data from 42 countries to examine the cointegration between energy intensity and GDP, capital stock, pop- ulation, and CO2 emissions as well as estimate their relationship with a pooled common correlated effects (CCEP) estimator. Then I investigate the he

Rethinking Partnerships: Exploring the EU’s Development Cooperation in Central America via Critical Discourse Analysis and Expert Interviews

The European Union (EU) is the largest provider of development aid in the world, considering the funds given by its institutions and Member States. Development cooperation has been a central policy theme since the Treaty of Rome in 1957, thus constituting a significant sphere of the EU’s foreign affairs. In this context, the concept of partnership covers a meaningful role, and has lately gained mo

A turnaround in organizational learning? - A case study on how Learning Experience Platforms Influence Learning in Organizations

The main objective of our study is to gain a more comprehensive understanding of how employees experience the utilization of a LXP to foster the learning flow within the organization. To address this issue, we challenge Jenkin's (2013) 5I framework, which did not consider the emergence of barriers to using and thus supporting learning flow through tools. This study involves qualitative researc

Sediment Transport and Erosion in Viskan River, South Sweden

This master thesis study presents the results of sediment transport analysis along Viskan, located in south Sweden. The main processes cover building a hydrodynamic model, studying parameters that define sediment transport, modelling sediment transport within the river, mapping out erosive stretches and comparing to observed eroded locations, and finally comparison of different transport functions

Potential for Enhanced Biological Phosphorus Removal in an activated sludge system for greywater

As the world's population grows, concerns about water scarcity and rising pollution such as phosphorus and nitrogen have increased significantly. Greywater has been considered by researchers as an ideal alternative to fresh water for decades, and several projects have been implemented to treat and recycle it for various reuse purposes. Greywater, which makes up about 80% of household water con

When judging candidate’s, less is more: How nondiagnostic information affects judgment in the process of personnel selection

Previous studies have found what is referred to as a dilution effect of nondiagnostic information when subjects make evaluative judgment tasks of future performance, meaning that the presence of nondiagnostic information makes predictions less extreme. However, a large study recently failed to replicate this effect. The hypothesis of this study is that judges can discard from obviously irrelevant

Importance Sampling in Wireless Communication Systems with Ultra-Low Error Rates

Simulation mimics the behaviour of real world processes or the system over time. It helps us to understand the impact of modification and the effect of introducing various interventions to a system. One such simulation method is known as Monte Carlo (MC) simulation, which has been utilized to evaluate the performance of digital communication systems over the last 70 years. MC has been the most ex

Designing a kidney perfusion machine

Today, it is difficult to take care of organs that could have been donated to patients. In Sweden around 92 000 people die every year yet less than 200 of them become kidney donors. UGLK Science AB has developed a patented technology for restoring kidney function which increases the time window for donations significantly. In this project, the exterior of the kidney perfusion machine used for this

What is the Problem of EBO? A Poststructural Policy Analysis of the Swedish Reception System

Sweden was once known for its open and generous refugee reception, with a mindset that was different from its neighbouring countries. However, this has changed in recent years. Due to an increased influx of people seeking asylum in Sweden, restrictive measures were put in place. The political discourse on migration shifted from a welcoming narrative to enforcing border controls and limiting access

"Why So Salty?" - Reducing Salt in Meatballs with Heterogenous Distribution

Processed food is a big contribution to the increasing intake of salt among the population, which today is the double of the recommendation stated by the World Health Organization. This high intake of salt affects the human health in such a way that it can increase blood pressure, which in turn can lead to cardiovascular diseases, which are already the main cause of death cause among the world’s p

A General SCADA Application for Water and Wastewater Treatment

The average Swede uses 140 liters of water everyday. This combined with the usage in industry means that Swedish municipal water treatment plants produce approximately 900 billion liters of clean and safe drinking water every year. This does not include the fact that all water flowing to a treatment plant needs to be treated before being sent back out into the environment. These facts hint at what
