Separating valuable minerals from waste rock is an important step in the production of metals. This is for copper ore done through a process called flotation. A flotation series consists of tank cells in series where the minerals are collected in a froth on top of the cells. The level control of the flotation cells is important in order to be able to collect the froth. The first four flotation cel

Data is a crucial resource for machine learning. But in many settings, such as in healthcare or on mobile devices, there are obstacles that make it difficult to utilize the available data. This data is often distributed between many clients and private, meaning that central storage of the data is inadvisable. Further, image data is often unlabeled and external labelling is impossible due to its pr

In countries such as the United States and the United Kingdom, the Covid-19 pandemic has caused the highest level of inflation since several decades. Explanations are sought after and disruptions of supply chains have been labeled the cause by many politicians. However, the empirical literature regarding the topic is limited. Hence, in order to extend the literature, this paper aims to investigate

Vi lever idag i en värld där en kontinuerlig ökning av både internetanvändning och psykisk ohälsa är en verklighet för den svenska befolkningen. Syftet med denna studie var att undersöka relationen mellan psykisk ohälsa, sociala behov och parasociala interaktioner (icke-reciproka beteenden och relationer med medieprofiler) bland svenskar som använder sig av livestreamingtjänsten Twitch.tv. StudienWe live in a world where a continuous increase of internet usage and mental illness is a reality for the Swedish population. The purpose of this study was to investigate the relations between mental illness, social needs and parasocial interactions (non-reciprocal behaviors and relationships with media profiles) among Swedes who use the livestreaming service Twitch.tv. The study aimed to investiga

The current reality is that cities are losing green spaces rather than creating more of them, leading to many urban challenges. Urban nature-based solutions (NbS), through renaturing urban landscapes, are seen as a promising solution to help cities deal with climate change and build a better future for communities worldwide. In Europe, specifically, NbS is also seen as a way of boosting green innov

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
