While many industrial processes have been thoroughly exposed to machine learning models, the realm of powder metallurgy is still underexplored. This thesis aims to investigate the potential for a machine learning model to predict the characteristics of metal powders after a reduction annealing process using time series process data from the furnace. A supervised learning model was developed to pre
Begreppet adaptation to the adverse effects of climate change är relativt nytt in internationell miljörätt. Begreppet adaptation är inte definierat i UNFCCC. Den här uppsatsen analyserar adaptation i ljuset av begreppet reparation i internationell sedvanerätt. Uppsatsen undersöker vad begreppen adaptation och reparation har gemensamt. Kan adaptation i UNFCCC ses som en möjlig utveckling eller förlThe concept of adaptation to the adverse effects of climate change is relatively recent in international environmental law. Adaptation is not defined in the UNFCCC. This paper attempts to address adaptation in the UNFCCC from the perspective of reparation under customary international law. It investigates what the concepts of adaptation and reparation have in common. Could adaptation in the UNFCCC
This essay investigates the impact of income inequality on economic growth in developed countries. The link is primarily investigated through the possible influence of income inequality on the four growth channels savings, human capital, population growth and labor force productivity. A theoretical model, based on an extended version of the Romer model, is presented, where a higher degree of incom
Since the Lisbon Treaty’s entering into force in 2009 it is stated in Article 6(2) TEU that the EU shall accede to the European Convention for the Protection of Fundamental Rights (ECHR). In the second sentence of the same article it is provided that “such accession shall not affect the Union’s competences as defined in the Treaties”. Attached to the Lisbon Treaty is also Protocol No 8 in which it
Cancer is a widespread and commonly fatal disease in constant need of new treatments. Traditionally, new pharmaceuticals have been tested in 2D models. This is not ideal, as 2D environments do not reflect the in vivo milieu of the cells. Instead, it has been increasingly suggested to implement 3D models, which are thought to be more predictive of in vivo responses to treatment. It has been shown t
Background: environmental impact from health care contribute to a substantial part of the public sector’s consumption based emission of greenhouse gases in Sweden. An issue, recognized by the health care sector itself, is the increasing use of single-use products. Objective: to compare environmental impact and cost differences between a single-use, ResposableTM, and mixed setup of the surgical in
Reaching the targets of the Paris Agreement requires acceleration of low-carbon energy transitions. At the same time, it is not fully understood why some technologies spread more rapidly and widely than others. This thesis advances our understanding of the diffusion of large-scale low-carbon technologies by bridging technology diffusion studies and political economy of transitions. Through combini
Abstract Purpose: The purpose of this thesis is to investigate how different types of fans experience personalization in sports marketing and to analyze how each Fan type can be motivated by understanding how their fan experience could be optimized further. Methodology: This study was a qualitative study. The study was carried out using an abductive approach where literature was combined with empi
Freevalve AB develops camless valvetrains for internal combustion engines using pneumatic and hydraulic systems. An air compressor is used to generate pressure in the pneumatic system. To further increase efficiency of the Freevalve system, a new compressor tailored to its purpose, is being developed in house. This thesis is part of the development of this compressor, which is a reciprocating pis
A growing environmental issue today is the amount plastic pollution in the ocean. To investigate how it might affect marine life, an important aspect is to study how plastics are transported by ocean currents and where it ends up. This can be done by use of Lagrangian simulation of plastic particles in computer ocean models. To improve the quality of the output from such simulations the number of
Protection of humanitarian aid workers (HAWs) is a challenging task. There are various reports on the topic where much research seems to focus on traditional physical attacks and intentional violence against HAWs (security) rather than the accidental event risks (safety) or discussing it separately. These risks are usually defined by the organization’s security risk management holding the power in
This Master's thesis in Biomedical Engineering investigates the performance and generalizability of linear regression models in context of prosthesis control for short residual limb amputees. This thesis uses intramuscular electromyography data, and a regression and emplys a regression technique called Elastic Net Regression - a technique that combines L1 and L2-regularization - to predict 1-D
Background: Respiratory agents may be detected in the oropharynx of healthy individuals. The extent of this condition and the reasons behind it are largely unknown. The objective of this study was to determine the factors associated with the presence of respiratory agents in the oropharynx of adolescents healthy enough to attend school activities. Methods: On a single day in December, samples from
Environmental impacts from incineration, decentralised composting and centralised anaerobic digestion of solid organic household waste are compared using the EASEWASTE LCA-tool. The comparison is based on a full scale case study in southern Sweden and used input-data related to aspects such as source-separation behaviour, transport distances, etc. are site-specific. Results show that biological tr
OBJECTIVE: The aim of the study was to examine the double locked-in phenomenon at work (i.e., being in a non-preferred occupation and non-preferred work place), and its associations to psychological health, physical health and job satisfaction. METHODS: A total of 136 municipal employees who visited a career coaching center (response rate 59%) participated in the questionnaire study. RESULTS: The
The semantic content, or the meaning, is the essence of autobiographical memories. In comparison to previous research, which has mainly focused on the phenomenological experience and the age distribution of retrieved events, the present study provides a novel view on the retrieval of event information by quantifying the information as semantic representations. The aim of the study was to investiga
To enhance the performance of gas turbine engines, high top-cycle temperatures are desired. However, the temperature is limited by current materials. To achieve the higher performance, and meanwhile maintain the metal temperatures of the combustors, vanes and blades below the allowable limits, sophisticated cooling techniques, such as impingement cooling, film cooling and convective internal cooli
