This thesis compares the wildfire evacuation simulation programme, WUI-NITY, against real-world data by analysing and comparing three wildfire events of the past. The wildfire events were all limited to be within the state of California and was further analysed based on the available quality of data derived of the chosen database. The goal with this thesis was to setup simulations based on the evi
The scope of this work is to help determine the functional improvement brought on by introducing a Bismuth germanate (BGO) Anti-Compton Scattering (ACS) shield system to a germanium COMPEX detector module. The COMPEX germanium detector module is already an extremely useful addition in examining gamma-ray spectroscopy. However, by introducing an ACS it is hoped to compound on these improvements yie
Simulations of domains with large differences in length scales across different directions are often computationally expensive because they require high mesh resolution, leading to long simulation times. This master’s thesis was done in collaboration with FS Dynamics Sweden AB and addressed the high computational cost associated with fully resolved 3D simulations. Inspired by semiconductor and ele
In this Bachelor thesis I examine the relationship between knowledge and power against the Zeitgeist of politicized science and depoliticized politics. I aim to uncover and problematize the understanding of legitimate knowledge production articulated in Responsible Research and Innovation (RRI), the framework for research within the current European research programme. I use Laclau and Mouffe’s di
The study considers the scheduling problem of identical parallel machines subject to minimization of the maximum completion time and the maximum tardiness expressed in a linear convex objective function. The maximum completion time or makespan is the date when the last job to be completed leaves the system. The maximum tardiness is indicated by the job that is completed with the longest delay rela
Vegetation indices derived from remotely sensed optical data are commonly used for crop monitoring in precision agriculture, but their information capability can be hindered by the presence of clouds. Consequently, areas with frequent cloud cover like the southwest of Sweden may have limited access to usable optical data. Nonetheless, the addition of synthetic aperture radar (SAR) data can provide
Thesis Purpose: We aim to research the relationships consumers build with subscription services and how those influence the totality of the consumer-brand relationship. Methodology: We adapted a qualitative research methodology with semistructured interviews and an abductive research approach. Theoretical Perspective: To research consumer relationships with everyday product subscriptions, we app
A major consequence of climate change will be changes in precipitation. Both amount and distribution will be affected and the changes will vary greatly between different places on the globe. In the inland parts of Pudukottai district, located in southern India, as well as in many other places, the result will likely be increased water scarcity and severe droughts, with dire consequences for food s
In the pharmaceutical industry when proteins are being formed, the solution often consists of different kinds of proteins and these have to be separated to a high degree. A common process for this is chromatography. In this work a system of chromatography columns were coupled in series to separate a mixture of three proteins. The system consisted of three chromatography columns with mixers in betw
Background: There is a need to develop methods of determining concentration and purity for two new affinity ligands, protein T and protein H, in order to ensure the quality of an industrial production of said proteins. Aims: To develop a High Performance Size Exclusion Chromatography, HPSEC, method to determine concentration and purity of protein T and to improve an existing HPSEC method for
In this paper, we present an adaptive spectral projection based finite element method to numerically approximate the solution of the wave equation with memory. The adaptivity is not restricted to the mesh (hp-adaptivity), but it is also applied to the size of the computed spectrum (k-adaptivity). The meshes are refined using a residual based error estimator, while the size of the computed spectrum
A low leakage rate sealant of 10 wt% ZrO2-added CaO–K2O–Na2O–BaO silicate glass for SOFC has been studied. The structure of the sealant is stable at high temperatures with leakage rates less than 10−4 sccm∙cm−1, and no crystal except for ZrO2 is found in XRD analysis after heating at 800 °C for 100 h. ZrO2 is distributed in the glass matrix and plays a supporting role in avoiding over-softening at
Polybenzimidazole (PBI) is currently considered as a membrane material for alkaline water electrolyzers (AWEs), and has to be fed with highly concentrated aqueous KOH electrolytes in order to ensure sufficient electrolyte uptake and conductivity. However, the harsh operating conditions significantly limit the lifetime of PBI membranes. In response, we here report on the synthesis and performance o
The CO2 Human Emissions project has generated realistic high-resolution 9 km global simulations for atmospheric carbon tracers referred to as nature runs to foster carbon-cycle research applications with current and planned satellite missions, as well as the surge of in situ observations. Realistic atmospheric CO2, CH4 and CO fields can provide a reference for assessing the impact of proposed desi
Background: Return-to-work (RTW) resources for persons with mental health disorders are limited and costs are typically shared by several stakeholders in society. Occupational therapists (OT) provide RTW interventions for this target group, however, increased knowledge of health, and employment effects, as well as costs are needed to better inform decision makers in their prioritisations. Aims/obj
The 2D semiconductors are important players in environmental and energy fields due to their unique catalytic and physical properties defined by their dimensionality. Versatile functionalities on one 2D matrix will enlarge its application scopes but require dedicated engineering paths. In this work, we present a cross-dimensional strategy by decorating 0D Co3O4 onto 2D Co(OH)2 to form a multifuncti
