This study investigates the optimization of Cleaning-In-Place (CIP) programs for Ultra-High Temperature (UHT) equipment used in oat drink production. The research comprises three main experiments: an Identification of the largest cleaning load product, an Assessment of improved CIP programs, and an Investigation of deposit composition in the flash cooler. The Identification of the largest cleanin

Introduction Illicit maritime activities frequently involve "dark" vessels that disable or manipulate their Automatic Identification System (AIS) signals to evade detection. This study evaluates the effectiveness of Synthetic Aperture Radar (SAR) and Optical imagery for vessel detection using both “manual” and automated Deep Learning (DL) methods while integrating AIS data to validate, i

Received Signal Strength Indicator (RSSI) circuits are critical in modern Wi-Fi receivers, playing a key role in power management and protecting the radio frequency (RF) front-end from saturation and potential damage. This thesis presents the design and evaluation of a novel rectifier circuit conceptualized for use in an RSSI system within an industry-standard 22nm CMOS node, specifically targetin

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 till​​The 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-

The most common controller in the process industry today is the PID controller due to its simple structure. A regular factory may have thousands of different PID controllers in use where each of them has to be tuned to work satisfactory. Doing this manually can become both a difficult and time consuming task where some knowledge for each process is required. Therefore, it is highly beneficial to h

This thesis investigates how place can be understood through assemblage theory and what that implies for the understanding of human relation to place. The framework has been widely used outside and within human geography, at a few instances related to place. Exploring place as assemblage is done through a case study of S:t Pauli cemeteries in Malmö. Main methods are walk along interviews and obser

Background: Purchasing and Supplier Relationship Management are becoming increasingly important as companies’ competitiveness increases. One part of this is Supplier Performance Evaluation (SPE), which is part of the final step in the purchasing process and can be performed in many different ways. SPE can ensure that suppliers are performing as expected and when not, actions can be taken. When mea

This thesis investigates if dependence on natural resources causes a delayed demographic transition. The Plurinational State of Bolivia is taken as an example as it is a country with a high share of Mining \& Oil activities in its economy. The method of investigation is a time series analysis covering the period 1900--2010. The results suggest that Bolivia's resource-depleting activities d

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
