The aim of this thesis is to identify a speaker in a video stream by only using the camera of a smartphone. This creates the opportunity for a mobile application to track the speaking participant during a conference call. Conference systems that include this feature use a microphone array to localize sound and who the speaker is. Mobile phones however, are generally not equipped with a microphone
With rapid urbanization and an increasing share of anthropogenic greenhouse gas emissions from cities, low-carbon urban transformations are critical for mitigating climate change. Local climate networks have been recognized for their potential to govern such activities. However, less is known about how such networks are implemented and managed as well as their capacity to accelerate transformative
Cities around the world are not only facing the impacts of climate change but are also increasingly charged with the responsibility to adapt. The city of Malmö in Sweden, facing the consequences of ever-so-present pluvial floods, has set an objective to increase the use of multifunctional Nature-based Solutions (NBS) in its urban stormwater planning. Nevertheless, despite evidence pointing at the
The permanent magnet synchronous motor, PMSM, is an efficient electrical motor that has seen a greater prevalence in the automotive industry from the increasing demand for electrical vehicles. Managing the temperature of the permanent magnet rotor is important to optimize motor utilization and avoid hardware failures. Direct temperature measurements of the moving rotor with a sensor are, however,
E-waste has had unwanted effects on the economy, health and physical environment of developing countries. E-waste activities in most developing countries including Ghana are dominated by the informal sector. Ghana, over the period, has had support from international organisations to manage its e-waste crisis. However, efforts to salvage the situation are often stymied by a myriad of factors. In 20
Overconsumption of clothes is a global environmental and social problem, where 80 billion new clothing is produced each year. Efficiency measures have focused on improving resource efficiency on the production side and improving clothing care on the consumer side. However, literature shows that these measures are not enough. Sufficiency shifts the focus to affluent societies consuming less, and un
The aim of this thesis was to fully characterize the enzyme WFp-105, including bioinformatic analysis, structural modeling, full activity and stability characterization and product determination. As well as for the enzyme WFp-37; optimize protein production in regard to expression strains and cultivation temperature, analyzing the genomic context as well as performing an initial activity detection
Production of building materials is connected to a great deal of environmental degradation, and demand for materials is expected to increase. Currently, the construction industry is responsible for 23 % of the global GHG emissions, 40 % of the raw materials consumed globally, and 32 % of the waste generated in Europe. With urbanization and an increasing population, more buildings are needed in the
In working to reduce this increasingly intensified effect of climate change, one of the key strategies employed by different countries around the world is to reduce Green House Gas (GHG) emissions from the energy sector. As they are one of the biggest contributors, the strategies include the employment of different mitigation actions and fading away from the conventional fossil fuel source to a mo
A Swedish Government Official Report was performed to investigate the possibility of a system with anonymous witnesses. This report examined whether incorporating anonymous witnesses could aid the legal process which otherwise may be hindered by primarily the culture of silence that exists within gang criminality. The investigation concluded that a system with anonymous witnesses should not be inc
Registreringshindret för tecken som endast består av en form som ger en vara ett betydande värde har varit en del av EU:s varumärkesrätt sedan den första gemensamma varumärkesdirektivet trädde i kraft 1989. Sedan dess har registreringshindret, som idag återfinns i artikel 7.1(e) iii VMF samt artikel 4.1(e) iii, fått stå i skymundan i förhållande till de andra två registreringshindren för tecken meThe exclusion for signs that consists exclusively of the shape which gives substantial value to the goods have been a part of trademark law of the EU since the first shared trademark-directive came into force in 1989. Since that day the exclusion, who today can be found in Article 7.1(e) iii TMR and Article 4.1(e) iii, have been forced to take a backseat in comparison to the other to exclusions fo
The wind power industry has long remained passive on broader sustainability issues, grounded in the perception that the industry is inherently linked with environmental sustainability. Within the past 5 years, there has been a dramatic change in the stakeholder and corporate perception of sustainability. Increasing expectations from stakeholders are pressuring wind OEMs to transition and advance c
Det har funnits en tradition i det svenska påföljdssystemet att särbehandla unga myndiga. Den 2 januari 2022 slopades delvis ungdomsreduktionen. Underlaget för den delvis slopade ungdomsreduktionen bestod av betänkandet Slopad straffrabatt för unga myndiga vilket utgjorde underlag för propositionen Slopad straffrabatt för unga myndiga vid allvarlig brottslighet. Propositionen ledde till att ungdomThere’s been a tradition of special treatment toward young adults in the Swedish legal sanction system. On January 2, 2022, the young adult penalty reduction was partially abolished. The basis for the partially abolished young adult reduction consisted of the report Abolished sentence reduction for young adults (Slopad straffrabatt för unga myndiga), which in turn formed the basis for the proposit
The aim of this essay is to perform a media study of how the identity of” immigrants” is constructed and which discourses about “immigrants” appear in one of the Swedish newspapers, Aftonbladet. With this study, I intend to shed light on how the discourse reflects and affects the broader marginalization in the Swedish society. This research is limited to the time period between January 2015, and D
Within the circular economy, alternatives to fast-fashion include second-hand clothing consumption. The narratives surrounding second-hand clothing have shifted from the stigma of old, dirty, smelly clothing to trendy, sustainable, and bargain items. The environmental benefits of second-hand are realised through the increased use-intensity and avoided production of new garments. However, these ben
As cloud service providers becomes more prevalent, so does questions related to cost efficiency of hosted resources. Payment models for cloud hosted resources tend to be either subscription based or pay-as-you-go for computing resources, in this case for compound metrics of CPU, Data IO and Log IO. In order to find necessary resource provisioning, previous methods have tended towards observing the
Border carbon adjustment (BCA) policies are increasingly discussed as an instrument to avoid carbon leakage; however, their social implications are not well understood. Nevertheless, the EU introduced its CBAM, which will take effect in 2026. After showing that distributional impacts in exporting countries were not considered in the policy process, I examine the potential effects in South Africa,
As climate change emerges as an urgent issue, the role of cities in responding to climate change is also becoming increasingly important. Cities can contribute to greenhouse gas reduction through local level climate action. In addition, it is essential for cities to develop local level adaptation plan in order to deal with inevitable climate change since the impacts of climate change local specifi
Climate adaptation finance is crucial, particularly for the most vulnerable countries, as these countries often face the worst impacts and are the least capable of adapting. While adaptation finance mobilization has increased over the last years, little has actually been channelled to the most vulnerable countries, with no concrete evidence of the prioritization of the most vulnerable countries in
Ofta har jag får höra att barockens kompositörer använde sig av den klassiska retorikens modeller när de komponerade musik. Frågeställningen för denna lecture recital har således varit att ta reda på hur detta samband mellan retorik och musik ser ut, samt att undersöka vilka av retorikens modeller jag som organist kan använda mig av för att förstå hur Bach komponerade sin musik. Som empiriskt uI have often been told that composers from the baroque era used the models of classical rhetoric while they composed music. The question for this lecture recital has thus been to find out what this connection between rhetoric and music looks like, as well as to investigate which of the rhetorical models I, as an organist, could use in order to understand how Bach composed his music. Bach's
