This report describes the research, conclusions, and result of my Master Degree thesis project in Industrial Design at Lund University. The thesis was completed during the spring semester of 2018. The work was carried out in collaboration with Trimble Geospatial in Danderyd, Sweden. The main purpose of this thesis was to explore the future methods of working with geospatial instruments - s
PFAS is a group of long-lasting chemicals with multiple known toxicological effects which has been found everywhere in nature. One of the possible source points of PFAS is via landfill through leachate leaving the area. It is therefore important to investigate and implementing remediation techniques to reduce the contamination risk. This thesis focuses on two components, first a literature study w
Microfluidic devices have so far not seen widespread use, even though they could potentially be cheaper, better and faster than traditional methods. A possible reason for this is the lack of a middle step between one-of-a-kind experimental devices and cheap mass produced devices. With ongoing improvements in resolution it is starting to look possible that 3D-printing will fill this role. This the
Purpose: To explore why brands lose control over their identity due to internal actions or lack of actions when needed. The paper examines the key elements brands should focus on internally to prevent brand identity erosion which can negatively impact brand performance. Methodology: This paper explains the relevance of brand identity by a literature review and further builds on fundamental causes
Modern medicine is rapidly evolving toward personalized treatments, where therapies are tailored to an individual’s genetic profile. This shift is driven by the promise of pharmacogenomics, which aims to match patients with the most effective medications based on their unique biological makeup. As a result, biotherapeutics made from biological sources like proteins, peptides, and antibodies are be
This thesis investigates the creation and assessment of a Federated Learning (FL) system which improves real-time object recognition for visually-impaired applications through embedded AI and edge computing. The research divides into two distinct sections. The initial phase of the FL validation used a CNN trained on the MNIST dataset to allow controlled testing of model updates and communication b
Characterising the performance of ICs is a daunting task. With every year that passes, transistor technology keeps advancing and reducing in size. We are at a moment where, due to working with sub-90nm processes, it is not possible to have complete control over the manufacturing of the chips on the silicon wafers. It is mandatory to characterise the behaviour of each transistor using statistics, n
This thesis explores a range of control algorithms for multimodal acoustophoresis, the process of manipulating particles in a fluid by simultaneously using several acoustic modes. The aim of the algorithms is to precisely guide particle trajectories in acoustofluidic systems, motivated by the demand for non-invasive, scalable manipulation techniques in biomedical applications such as single-cell a
This research analyzes the climate adaptation strategy of Copenhagen, focusing on cloudburst (rain-based) flooding and the use of infrastructure to mitigate damage. This strategy is analyzed through document analysis and structured interviews, using a theoretical framework of political ecology and urban green assemblages. This framework focuses analysis on the role of actors (human and non-human)
This master thesis analyses the effectiveness of smart beta strategies in improving the returns of index funds within the Nordic and Baltic regions. The study employs a mixed-method approach, combining qualitative literature review with quantitative empirical analysis of historical market data, focusing on key stock indices in Sweden, Denmark, Finland, Iceland, Norway, Lithuania, Latvia and Estoni
The T-REX neutron spectrometer at the European Spallation Source will use Multi-Grid Technology, which is a voxelised proportional counter relying on 10B4C coatings to detect neutrons scattered by the sample under investigation. Measurements of the position dependence of pulse-height and relative detection efficiency of a Multi-Grid prototype of the T-REX spectrometer are presented for two differe
Essentially all academic research of today relies on analysis of data from a wide range of sources. Several underpinning, and rapidly developing, technologies are supporting the analysis of this data. Visualization serves as an interface to this ecosystem of tools and methods and integrates them into environments supporting scientific workflows, effectively sharing cognitive load between computers
Shared ground heat exchange can deliver low-carbon electrified heat where individual heat pumps or heat networks are not feasible, such as in terraced homes. However, there is a policy gap around these mid-scale heat solutions. We outline the benefits and challenges of shared ground heat exchange, and actions needed by policy, housing, and innovation stakeholders to support further deployment.
Money is central to capitalism and its sustainability crises. This article argues that it is not money itself, but its internal design and governance – how it is created, distributed, and governed – that drives inequality, ecological degradation, and unsustainable growth. Yet, money’s architecture is not fixed; it can be reimagined to foster fairer, greener economies.Approaching money as a socio-t
Spiral spin liquids are an exotic class of correlated paramagnets with an enigmatic magnetic ground state composed of a degenerate manifold of fluctuating spin spirals. Experimental realizations of the spiral spin liquid are scarce, mainly due to the prominence of structural distortions in candidate materials that can trigger order-by-disorder transitions to more conventionally ordered magnetic gr
Time-resolved experimental techniques are increasingly abundant at storage ring facilities. Recent developments in accelerator technology and beamline instrumentation allow for simultaneous operation of high-intensity and timing-based experiments. The MAX IV facility is a state-of-the-art synchrotron light source in Lund, Sweden, that will come into operation in 2016. As many storage ring faciliti
This paper illustrates a novel method to analyze artificial neural networks so as to gain insight into their internal functionality. To this purpose, we will show analysis results of some feed-forward-error-back-propagation neural networks for image processing. We win describe them in terms of domain-dependent basic functions, which axe, in the case of the digital image processing domain, differen
Establishment of human embryonic stem cells (hES) from surplus human IVF embryos has been successful when both fresh and frozen-thawed cleavage stage embryos have been cultured to the blastocyst stage. This study reports the characteristics of the starting material, the blastocysts, for hES cell lines that were first derived at the University of Gothenburg, Sahlgrenska University Hospital in 1999.
A high resolution injector system has recently been installed at the Lund 3 MV tandem Pelletron accelerator. The new injector, designed mainly for Al-26 ions, will increase the experimental potential of the Lund AMS facility considerably. High quality energy- and mass-resolution is obtained by using a 90degrees spherical electrostatic analyzer followed by a 90degrees magnetic analyzer. The injecto
Portfolio choice by full-scale optimization applies the empirical return distribution to a parameterized utility function, and the maximum is found through numerical optimization. Using a portfolio choice setting of three UK equity indices we identify several utility functions featuring loss aversion and prospect theory, under which full-scale optimization is a substantially better approach than t
