n instrument suitable for measuring the total water content both as small liquid droplets and as vapour in the air, in water mist total flooding extinguishing tests, is presented. The instrument consists of a heater and a Vaisala humidity meter. The Vaisala humidity meter is capable of measuring relative humidity at temperatures up to 180°C. The instrument has a measuring range of 0-600g/m3, a sam
By adapting gear changes and cruise control of a Heavy Duty Vehicle (HDV) to road inclination, fuel and time savings can be achieved. In this thesis is presented a novel method of predicting the upcoming road topography, by constructing a geographical and topographical self-learning map from which a route prediction is made. The system is designed to simultaneously produce the desired road grade o
Connective Boundaries is a personal reflection on how a worthy and comforting funeral ceremony can be designed without religious convictions. It begins with the acknowledgment that, today, the tension between the personal and the social experience of death has led to attempts to sanitize, hide and compartmentalize both the mourner and the deceased, alienating both. This project investigates the
With global warming and increased uncertainty about future vehicle fuel supply, the need for fuel efficient vehicles is growing. In this Master Thesis, design and implementation of a control strategy for fuel efficient deceleration is presented. The resulting deceleration controller, implemented in Embedded Matlab and Simulink, provides autonomous deceleration functionality to a vehicle cruise con
The DARPA Grand Challenge (DGC) 2005 was a competition, in form of a desert race for autonomous ground vehicles, arranged by the U.S. Defense Advanced Research Project Agency (DARPA). The purpose was to encourage research and development of related technology. The objective of the race was to track a distance of 131.6 miles in less than 10 hours without any human interaction. Only public GPS signa
The aim of this project was to determine the consequences of the large-scale introduction of wood-based biofuels in the road transport sector. Therefore a model has been developed to project the demand for wood in Sweden in the period from 2007 to 2050. The wood-using sectors that were taken into account are: the sawmill industry; the paper and pulp industry, which was split in three: integrated c
This thesis focuses on how online activists react to online censorship imposed onto them by social media platforms and how the reactions shape the activists’ responses to the censorship. It does so by deploying a qualitative interview study design onto how Swedish individuals who advocate for Palestine online experience and respond to digital censorship on Meta’s social media platforms. In the st
Across Europe, breeding bird species are decreasing in several types of habitats. Deciduous forest specialist birds are facing a loss of habitat due to the forest management that removes important key components in the forest, e.g. dead wood. Already in Sweden three woodpecker species that are deciduous forest specialist have decreased in population: one has become locally extinct (middle spotted
Climate change poses serious questions about how social work can address environmental issues. This study departs from an ecosocial approach and aims to explore how social workers in Sweden conceptualize and respond to climate change in social work practice. This study employed a thematic analysis where the collected data consisted of qualitative semi-structured interviews with four social work pr
This study aims to explore social workers' perceptions of their own capacity to work with children exposed to violence, focusing on maintaining the child's well-being and safety. The study examines the opportunities and limitations within their area of work, considering factors like consent, national laws and professional experience. The study employed qualitative methods to explore social
Society relies on the continued operation of software systems, from healthcare to social media platforms. These systems can be engineered to be highly reliable, but complexity assures surprise. People have the ability to manage this complexity, filling gaps in design by recognizing, diagnosing and correcting anomalies. Rarely can surprises be managed by individuals alone. When engaged in anomaly r
This master thesis explores the neural encoding of speech features for hearing aid users. The study utilizes electroencephalography (EEG) and audio data from an experiment that stimulates a Cocktail Party scenario. This is a complex auditory scene, especially difficult for individuals with hearing impairments. The primary objective of the study is to investigate how different acoustic and linguist
The global food system is a cause of the worldwide poly-crisis in climate change and ecological decay. Ecological food systems have been emerging to contest the ruinous food production model. This thesis explores one branch of ecological food production: urban farming. Focused on the Swedish context, cases in Växjö, Malmö, and Göteborg were analyzed to examine how urban farms and involved agents n
There is a growing demand from policy makers for businesses to help close the consumer intention-action gap for sustainable product choice and strengthen the green economy. Moreover, there is increased interest from consumers in brands that are transparent about their environmental impact. This is not least the case for the focus sector of this study, food products, an industry responsible for aro
Background: The case company is a Swedish family-owned business, operating in the agri-food industry. Their philosophy is to develop, produce, and sell frozen products from the vegetable kingdom with a focus to be organic and convenient. The company has realized that the production layout and the material flow cause a lot of waste and have great potential for improvements regarding efficiency in p
Chronic obstructive pulmonary disease (COPD) is a progressive lung disease characterized by an accelerated decline in lung function due to narrowing and fibrosis of small airways and irreversible alveolar tissue destruction termed as emphysema. To date, no effective treatments exist which can reverse the damaged state of the affected lungs. Stem cell therapy represents a promising approach for tar
This paper evaluates the performance of the Long Short-Term Memory (LSTM) Neural Network for forecasting energy production from combined heat and power (CHP) plants in Stuttgart, Germany. The dataset consists of high frequency time series data and exhibits multiple seasonal patterns. A key challenge addressed in this study is the presence of a systematic reporting delay, where the most recent four
