In ordinary public rooms such as classrooms and offices, the base line of acoustical treatment is an absorbent suspended ceiling. Due to the non-uniform distribution of the absorptive ceiling material, the scattering as well as the absorption properties of furniture will have a significant effect on room acoustic parameters such as reverberation time, speech clarity and sound strength. In particul
This thesis investigates the viability of using Fully Homomorphic Encryption and Machine Learning to construct a privacy-preserving biometric multi-factor authentication system. The system is based on the architecture described as ”Model K - Store distributed, compare distributed” in ISO/IEC 24745:2022 and uses the Torus Fully Homomorphic Encryption scheme proposed by Chillotti et al. (Journal of
This essay investigates the impact of classroom gender composition on the mental health of adolescent students. Using data from the Health Behaviours of School-aged Children survey in the Czech Republic, we exploit idiosyncratic classroom variation in the gender composition within the same schools across different grades. We find that a higher proportion of female peers in the classroom has a detr
The presence of fog, or condensation, poses significant challenges in various fields, including surveillance cameras. The main issue is that fog obstructs the camera's view, essentially rendering the camera ineffective for surveillance. Currently, preventative measures such as heating the camera are a remedy at the cost of significantly increased power consumption. This master’s thesis is aime
Denna studie syftar till att undersöka hur cancelleringsprocesser ser ut i samband med skandaler för influencers och hur de utvecklas under tidens gång. Detta görs i form av en fallstudie, närmre specifikt skandalfallet med Margaux Dietz som inträffade år 2022. För att kunna dra vetenskapliga slutsatser baserat på empiri som följer narrativet, tar rapporten fäste i två teoretiska utgångspunkter - This study aims to investigate the dynamics of cancellation processes in relation to scandals involving influencers and how they evolve over time. It is conducted through a case study, specifically focusing on the scandal involving Margaux Dietz that occurred in 2022. In order to draw scientific conclusions based on empirical evidence that aligns with the narrative, the report adopts two theoretic
The spread of artificial light on Earth increases annually. One of many causes of this spread is due to increased street lighting and artificial light at night (ALAN). Lighting is one of the many necessities for people to feel safe. On the other hand, ALAN, which contributes to light pollution, negatively affects biological functions and thus biodiversity. The purpose of this study was to investig
This research project investigates Swedish upper secondary school students’ experiences of engaging with English fiction, both within and outside of the context of their English language classroom. Three focus group interviews were conducted with 18 upper secondary school students from the southern parts of Sweden. Based on the collected data, five themes were identified. The themes were 1) the pe
Undersökningar tyder på att skärmanvändningen hos barn och unga ökar och att medieanvändning går allt lägre ner i åldrarna. Barn och unga matas dagligen med en uppsjö av sociala medier. Den ökade tiden för skärmanvändning bidrar till allt mindre tid för socialt samspel och att använda kroppen för fysisk aktivitet. Barn är mottagliga för påverkan där just skärmanvändning kan spela en betydande roll
Recycling has become increasingly relevant to solve environmental problems related to the enormous amount of plastic waste. Recycling plastic has many environmental benefits, but it is challenging to find applications where recycled plastic can provide the same functionality as virgin plastic. This thesis highlights the challenges of using recycled High-density polyethylene (HDPE) in pipe applicat
This study investigates the working life of people with immigrant backgrounds who work as language supporters to help the integration of refugees in a municipality in Sweden. Five language supporters were interviewed about their working experience in the municipality. Applying Joan Acker’s concept of inequality regime and Anders Neergaards’s concept of included subordination, the results of the st
De ökade kraven kring hållbarhet från organisationers intressenter har bidragit till att det har blivit allt viktigare att utvärdera sin roll i hållbarhetsutvecklingen. Triple bottom line (TBL) kan ses som ett ramverk som hjälper till att forma hållbara strategier eftersom det uppmuntrar till balans mellan de tre dimensionerna; miljömässiga, sociala och finansiella. Det har länge arbetats med tydl
Bakgrund: Amning är en mänsklig rättighet och har ett flertal hälsofördelar för både moder och barn. Många kvinnor upplever amningen som en prestation. För att uppnå fungerande amning krävs adekvat rådgivning från kunnig hälso- och sjukvårdspersonal, i syfte att bland annat stärka kvinnors självkänsla. Rådgivning från sjuksköterskor och annan vårdpersonal har visat sig påverka initiering och durat
This study was done to get an understanding of how tillage effects biodiversity in agriculture soil. Therefore, this study focused on the soil organisms and various physical and chemical processes that can affect them. Soil organisms are crucial to agricultural landscapes as they perform biological processes that improve soil structure, nutrient cycling and decomposition. To ensure food produc
This study examines the perception and acceptance of the Swedish tax paid school meals, its sustainability aspects and what factors that affect the students in their food choices in the municipality of Ängelholm from a student perspective. The guidelines for school meals in Sweden is for it to be healthy but in recent years also more sustainable. A common way to enact upon the sustainable factor i
Rap music has been controversial ever since the music genre took off. Themes such as violence, drugs and aggression have been themes portrayed in the genre since a long time ago. The purpose of this study was to study How do Swedish rap artists within the gangster rap scene describe their everyday life through their lyrics? By analyzing ten different artists and a total of 76 songs through a thema
Human beings in modern society spend more than 90% of their time indoors to live, work, and socialize. To improve health, quality of life and task performance, integrative lighting is designed to give the right light at the right time at the eye to stimulate circadian entrainment. Current designs for integrative lighting consider rooms as black boxes, overlooking the contribution of daylight to th
To better understand collectivity in high energy physics, the heavy-ion collision model Angantyr was developed to be included in the event generator Pythia. In this model, proton-proton collision phenomenology is extrapolated to heavy-ion collisions without assuming a thermal plasma for particle production. Hence, this model may help disentangle possible thermal and non-thermal phenomena contribut
This study investigates interculturality in health communication and deriving power relations. The Bilharzia Storytelling Lab 2022 in Kigali is a health communication program devoting significant attention to the role of culture and representing a new approach to respectful health communication practices. Exploring the Storytelling Lab methodology and its roles provides insights into the innovativ
