Caches today are an important part of mitigating the performance gap between processors and memory which has increased during the last 50 years. Cache policies are vital for the performance of caches and their mission is to select the data which should be contained in the cache and are therefore important for the performance of processors. Graphics processors are very memory bandwidth intensive an
Key words: Innovation, start-ups, exploration, exploitation, formal networks Purpose: The purpose of this thesis is to explore the effects of formal network participation on exploration and exploitation activities in start-ups. Methodology: Following a cross-sectional design, an explorative study was conducted using semi-structured interviews. 18 interviews were performed with representatives fr
Municipal wastewater contains a lot of compounds that could be seen as resources. Nitrogen, phosphorus and potassium are common ingredients in fertilizers and can all be found in wastewater. Nowadays only a small part of the nutrients found in wastewater are used on arable land. Urine contains the most of the nitrogen, phosphorus and potassium secreted by humans. Source separation of urine is a wa
Purpose: The purpose of the research is to analyze managers’ use of accounting discretion in goodwill impairment losses of European firms in 2020 – a year of financial distress caused by the COVID-19 pandemic – and whether the discretion employed reflects earnings management. Methodology: The difference in earnings between impairers and non-impairers is analyzed by employing a Mann-Whitney U-test
Abstract William Gibson’s influential Cyberpunk novel Neuromancer (1984) raises many questions about the effects of rapid technological advancements. The novel presents a Baudrillardian hyperreal situation for the individual characters in the story. Their desires and goals are shaped and directed by the environment in which they live. This essay builds on the work of scholars who have approached G
Visual object tracking is a fairly easy task for humans but a challenging problem in computer vision and thereby in humanoid implementation. Most of the existing object tracking evaluations are performed with prerecorded video footage, often with a stationary camera. This is not representative of a humanoid platform. The aim of the present thesis was to evaluate different object tracking algorithm
A shift in the Swedish welfare state and diminishing resources has prompted new ways to address social and welfare provision issues. It is here that cross-sectoral social innovation collaborations have surfaced as an answer. Previous research shows that working with collaboration and social innovation has similar challenges and that there is a lack of studies about power and organisational issues
The study of the impact of social capital on economic outcomes is currently on the rise. Social capital is a multidimensional concept hard to grasp. This paper makes an attempt to comprise such range of dimensions and analyzes its impact in a potential channel for growth, financial development. Three rural-based provinces of Vietnam are the places where this analysis takes upon. Vietnamese society
The thesis focuses on designing and simulating an 8-bit high-speed fully differential pipelined Analog to Digital Converter (ADC) in the 65nm Complementary Metal-Oxide-Semiconductor (CMOS) technology by using the software Cadence Virtuoso. The aim is to increase the operation speed of the ADC for communication systems without reducing the performance, in the meantime, the low power consumption and
Alzheimer’s disease (AD) is characterized by amyloid-β (Aβ) and tau depositions as well as neurodegeneration, and is typically accompanied by a progressive decline in episodic memory. Previous research proposes two neural memory networks that process different stimulus domains. Specifically, a posterior-medial (PM) and an anterior-lateral (AL) network handle scene- and object-specific information,
This thesis analyses the relationship between sustainability transformations and grassroots movements in Monteverde, Costa Rica. The focus is toward understanding the influence of community-based initiatives on transformations that have sustainability as a goal, due to their potential for shaping society and addressing challenges such as climate change. The study also examines the emergence and de
3D city models are valuable tools for visualization and analytical purposes in the urban environment. A popular format for city models is CityGML, an open data model that can be used for storage and exchange of 3D city models. However, using city models based on CityGML has appeared to be a challenge as there is a limited number of software applications that are able to read them. Complexity in Ci
Det här examensarbetet beskriver ett projekt som har genomförts med Phasor Solutions Ltd om att simulera olika fel som kan uppstå i en sfärisk närfälts skanner (SNFS). En SNFS är ett komplicerat mätsystem som gör det möjligt att göra exakta mätningar för en halvsfär runt antennen som testas. Då frekvenserna som används i skannern är höga, geometrin är komplicerad och att transformation mellan närfThis thesis covers the work that has been carried out with Phasor Solutions Ltd on simulating possible errors in their spherical near field scanner (SNFS). A SNFS is a scanner that enables exact measurement to be taken in a complete hemisphere around an antenna under testing (AUT). Due to the high frequency, complex geometries and the fact that the transformation between near-field and far-field d
Lake sediments have lately been explored as a 10Be archive, complementing previous research on ice cores and marine sediments. 10Be is an important proxy as it can be used to study past solar activity, a factor which affects the climate. Where other methods studying solar activity only cover a brief period of history, 10Be has the potential to go further back in time. The concentrations of 10Be st
Parkinson´s Disease is the second most common neurodegenerative disease. Only a small number of cases appear to be caused by genetic mutations, meaning most cases arise due to unknown mechanisms. While there are reported to be multiple causes of the disease, what links all cases is a small protein called α-synuclein whose aggregation appears to correlate to the pathology and progression of the dis
The demand for renewable energy is constantly increasing and in order to compete with other sources of energy the wind energy output has to increase. The power output from wind turbines are highly dependent on the swept radius of rotor blades. Increasing the length of the rotor blades will increase the weight of the blades, resulting in higher demands of the structural performance, but also introd
