This thesis studied methods of improving a background model for a data processing pipeline of LiDAR point clouds. For this, two main approaches were evaluated. The first was to implement and compare three different models for detecting ground in a point cloud. These were based on more classical modeling approaches. The second was to use Deep Learning for semantic segmentation of point clouds and t
Haloacid dehalogenase (HAD)-like hydrolases represent a vast superfamily characterised by their ability to form covalent enzyme-substrate intermediates facilitating the cleavage of C-Cl, C-P, or CO-P bonds. Within this work one member of this superfamily, HAD from Thermotoga neopolitana (HADTn) exhibiting a phosphatase (P-O bond cleavage) like activity was investigated in the context of altering t
Resource consumption is becoming increasingly scarce with an increase in the global population. Due to the increased resource consumption, the current linear economy model is unsustainable in the way it operates. The limitations of the linear economic model have been at the forefront to aspire circular economy in practice. Numerous factors have identified the need for the circular economy to emerg
The purpose of this thesis is to determine how electric vehicle trucks can meet the needs of customers in the urban building and construction sector. This sector contributes significantly to greenhouse gas (GHG) emissions, and also creates noise and other disturbances in urban environments. There are multiple benefits that come with electric trucks, which can address these issues if they are used
This thesis explores the activism of AUB students for social and political change promoting secularism on campus and in the Lebanese society and politics. It draws from 17 interviews, a focus group and observations during four months of fieldwork. It looks into the ways how members of the AUB Secular Club employ the notion of secularism, and how diversity in the AUB campus facilitates the collecti
Förenta Nationernas fredsbevarande operationer har under nästan två decennier besvärats av anklagelser om sexuellt utnyttjande av och sexuella övergrepp på civilbefolkningar. Flera rapporter visar inte bara att organisationens fredsbevarande styrkor begår dessa brott mot just de människor de fått i uppdrag att beskydda, utan också att de undgår ansvar och straff. Denna uppsats undersöker och utvärUnited Nations peacekeeping operations have, for the better part of two decades, been plagued by allegations of sexual exploitation and abuse of local civilian populations. Several reports indicate not only that peacekeepers exploit and abuse the very people they were sent to protect, but also that these crimes routinely go unpunished. This thesis examines and evaluates the different methods of ho
Personal på sjukhusavdelningar upplever ett antal problem kopplade till administrativa uppgifter. Bland dessa problem ingår att behöva dokumentera samma information i flera system, samt svårigheter vid överlämningar mellan skift. Den nuvarande produkten Pulstavlan, utvecklad av Stretch Care AB, har som mål att lösa dessa problem. Pulstavlan är dock stationär och möjliggör därför inte för vårdpersoStaff in hospital wards experience a number of issues related to administrative tasks. These problems include needing to document the same information in multiple systems, and difficulties in shift handovers between staff members. The existing product Pulstavlan, developed by Stretch Care AB, aims to solve these issues. However, as the product is stationary, it does not enable staff to bring the i
Abstract Aim: Today there is a double-sided challenge for the transport sector. First, it needs to adapt and be able to respond to an increasing demand in mobility of goods. Second, pressure is increasing to adopt to low-emission mobility strategies. As the phenomenon of growing environmental awareness is increasing in general in Sweden, this study sets out to investigate if this is something tha
This thesis aims to explore the meanings behind rural reading rooms (tushushi) in Yunnan Province, PRC. Rural reading rooms are small libraries attached to the village Party compound in Chinese villages; for the past decade 600 000 reading rooms have been established in administrative villages in China, and now benefit more than 1 billion farmers in what is arguably the world’s most important deve
Sustainability philosophers claim that we are at the impasse of stories, finding ourselves in a blank chapter between the old and the new. The old story, characterized by separation, technological arrogance and human superiority over nature, is unfolding in an ecological crisis giving space for a new narrative defined by inter being, cooperation and balance. It has been put forward that this crisi
Plastkonsumtionen har ökat markant över tid och har utvecklats till ett viktigt material i dagens samhälle, men med utmaningen att råvaran främst kommer från fossila källor. Användningen av plast är i linje med den linjära ekonomin och den så kallade slit-och-släng-kulturen, vilket bidrar till felaktig hantering av plastavfall och en ineffektiv användning av resurser. Detta kräver en övergång tillThe consumption of plastic has significantly increased over time and has emerged as a vital material in contemporary society, primarily derived from fossil fuels. Use of plastic aligns with the linear economy of “take, make, dispose”, which contributes to mishandling of plastic waste and an ineffective use of resources. This calls for a shift towards a circular economy, advocating for the princi
Intrafractional prostate motion during external beam radiotherapy of prostate tumors has been reported as a limiting factor in accurate treatment delivery. Technology for real-time image-guided radiotherapy has been introduced for tracking and for compensating prostate motion during treatment and could allow for reduced target margins. This project investigated the geometrical accuracy of Radixact
The knee menisci distribute and dampen mechanical loads. Vulnerability to injury and disease of the meniscus is a global issue, particularly concerning osteoarthritis. The connection between the breakdown of meniscal tissue and its mechanical response is not entirely understood. This thesis seeks to contribute to filling this knowledge gap by developing and implementing a digital volume correlatio
This thesis reviews Colombia's waste management policies, decrees, and laws to scrutinize the country's discourses on waste management and their potential impact on waste pickers. Employing critical discourse analysis and Bacchi's What's the Problem Represented to be? (WPR) approach, the study critically examines these discourses. It identifies the prevailing discourse of free comp
This study investigates the experiences of individuals who have left a criminal lifestyle and the factors influencing their journey. Through interviews with both individuals active in a criminal lifestyle and those who have successfully transitioned to a law-abiding life, this research explores the motivations for leaving a criminal lifestyle and the challenges faced during this process. Key findi
Kemira Kemia AB produces a water treatment chemical named ”PIX-Sulfate”, where “PI” stands for “poly iron x”, and the “x” represents a conjugate ion, such as chloride or sulfate, in this case, sulfate. The main process for producing PIX Sulfate at Kemira’s plants today is to dissolve magnetite in diluted sulfuric acid and to oxidize the resulting liquid using oxygen. Currently, this process is car
The Bangladeshi Gen Zs and university students demonstrated a revolutionary example of civic engagement, participatory culture, subcultural identity formation, and reformation during the Student Quota Reform Movement in July, leading to the July massacre where thousands of protesting students were tortured and shot to death in public. The movement happened as an enraged response against the announ
Neurogenesis, the formation of new neurons from neural stem cells, persists throughout life but with a rapid reduction during aging. With such a reduction, decline in cognitive abilities and the occurrence of neurodegenerative diseases are imminent. It is, therefore, important to better understand the role of key factors involved in the reduction of neurogenesis during aging. Microglia, the brain-
