Researchers in the field of Galactic Archaeology have entered the era of industrial revolution. Upcoming surveys are planning on observing tens of millions of stars and high precision and accuracy must be ensured when deriving their stellar parameters and elemental abundances. Unconventional data-driven techniques hold the promise of efficiently dealing with these vast collections of data while st
Collection and delivery points have become increasingly important due to the current e-commerce trend. In addition to the general rise within e- commerce the extraordinary situation with an ongoing SARS-CoV-2- pandemic has further increased the demand for sufficient parcel deliveries. The purpose of this master thesis has been to investigate how different stakeholders connected to e-commerce measu
This master thesis aims to investigate downlink positioning techniques and improve fifth-generation (5G) cellular positioning performance in the indoor office scenario. In the thesis work, we target in the indoor office scenario because it is a typical deployment scenario standardized in 3GPP release 16. To analyze the positioning techniques, we develop a simulator in MATLAB. In the simulator, t
The purpose of this thesis is to explore the factors, circumstances and insights influencing Swedish organizations in their own transitioning process towards AI. The work conducted within this thesis results in a qualitative report where a number of focus areas are reviewed in an attempt to first provide a holistic picture surrounding the definitions, contexts, activities and mindsets involved in
Maskininlärning är ett område inom artificiell intelligens som handlar om metoder för att träna datorer att lära sig regler för att lösa en uppgift. Dessa regler har inte programmerats av en människa, utan datorerna måste upptäcka dem genom att lösa optimeringsproblem. De här optimeringsproblemen kan också ses som gradientflödesproblem, en typ av differentialekvationer, vilka kan lösas med hjälp In supervised machine learning, training neural networks requires solving optimization problems. These problems can be restated as gradient flow problems and solved numerically using time-stepping methods. In order to study the behavior of these time-stepping methods, in the context of solving the aforementioned optimization problems, a framework in Python was developed. This framework is based o
Mekanismerna bakom LL-37 inducerad celldöd Varje år dör det cirka 700 000 människor globalt till följd av infektioner orsakade av multiresistenta bakterier. Sedan upptäckten av penicillin har vi människor överkonsumerat antibiotika. Läkare världen över har skrivit ut antibiotika för att behandla banala infektioner som kroppens eget immunförsvar egentligen hade kunnat klara av på egen hand. Dessut
Introduction: The world has witnessed a global trend of increasing obesity, which is directly linked to non-communicable diseases, such as type 2 diabetes (T2D). The epidemic of obesity is largely associated with consumption of high calorie diets and low physical activity. Food choice and exercise have a big impact to prevent obesity and T2D making these diseases highly related to personal lifesty
The recent COVID-19 pandemic crisis has resulted in great uncertainty and potential losses to the financial market. Investors must find the safe haven and hedge currencies in the current crisis to manage portfolios. In this paper, I demonstrate how to use the dynamic conditional correlations (DCC) model with student-t error distribution to assess the role of foreign exchange, cryptocurrencies, and
The prevalence of algorithms and machine learning technologies in society opens up a vast sociological territory. In this thesis, I investigate interactions that transpire between users and recommender systems which statistically predicts and suggests specific items based on their and similar profiles’ data traces in the context of social media platforms in everyday life. Fusing several data colle
Efter att Greta Thunberg i augusti 2018 satte sig utanför riksdagen med ett plakat med texten: “Skolstrejk för klimatet”, har en snabbt växande rörelse av unga klimataktivister startat, med budskapet att äldre generationer och politiker har svikit dem när de ignorerat klimathotet. Studien vill undersöka vad som fick ungdomar som tidigare inte deltagit i protester att agera och vilken roll Greta Th
Vocational education and training (VET) is generally believed to be a tool for the promotion of youth employability ('VET for work') and economic productivity ('VET for growth'). This rather narrow understanding has been challenged by a growing number of development scholars, who argue that it fails both theoretically (to capture the complex nature of human beings), and practically
Stor risk för mjölkallergiker att äta på restaurang i Malmö Vågar allergiker äta på restaurang? Går det att lita på att maten innehåller det som restaurangpersonalen säger att den gör? Innehåller grädde, ost och yoghurt mjölk? Att äta på restaurang kan vara utmanande för en allergiker eftersom restauranger är bland de vanligaste platserna där allergiska reaktioner inträffar. Omkring 15 procentFoodallergy is on the rise in Sweden and the rest of the world and is a global health issue. Milk protein is the allergen that causes the most allergic reactions in Sweden and those who are highly allergic to milk risk going into an anaphylactic shock which in worst case can be fatal. Eating at a restaurant can be a challenge for a person with food allergy since this is where the majority of aller
I det här examensarbetet undersöks hur en förtätning av Veberöd kan gestaltas, dels på ett hållbart och centrumutvecklande sätt, dels i dialog med Veberöds identitet, historia och karaktär.
Green Bonds are debt instruments issued by companies whose proceeds are used to finance projects that promote sustainability. Consequently, they act as measures of a company’s contribution towards the environment. However, they are often criticised as virtue-signalling. This paper explores the issuance of green bonds on two levels: the corporate level and the role of the region, here the Nordic Re
Meal-kit boxes are considered a solution to reduce greenhouse gas emissions by reducing the food waste in the supply chain and households. Nevertheless, the consumers are concerned about the amount of packaging that comes with such a box, which is connected to higher carbon emissions than a grocery store meal. Thus, HelloFresh, a global market-leader in meal-kit boxes is driven to find more sustai
Syftet med studien var att undersöka hur biståndshandläggare och kuratorer, som möter äldre i sitt dagliga arbete, resonerar kring samverkan mellan socialtjänst och hälso– och sjukvården när det kommer till äldres psykiska ohälsa. Studien var av kvalitativ karaktär och innefattade sex semi-strukturerade intervjuer med tre biståndshandläggare inom äldreomsorgen och tre kuratorer inom hälso- och sjuThe purpose of this study was to explore how care managers and counsellors, who meet seniors in their daily work, experience the interaction between social services and health care when it comes to the elderly's mental illness. The study had a qualitative approach and included six semi structured interviews with three care managers in senior care and three counsellors in health care. Questions
Within the last decade, the alt-right movement has migrated from secluded corners of the internet into mainstream media. This migration, and subsequently gained following, challenges traditional views on security by bringing forth social actors that securitize, despite a lack of authority. This takes place on online platforms, such as YouTube, where the political and non-political coexist. This t
My aim of the project was to create a table with the same purpose as the Memphis Group had in the 1980s, furniture that does not have the function as the main topic, the experimental playfulness with shapes, materials, and colors are the primary. My method has focused on the Memphis Group's philosophy, to be inspired by the coloring, design of volumes and materials, and also the aim of provoc
Tidigare forskning har pekat på betydelsen av kundrecensioner och e-förtroendets förhållande till användandet av kundrecensioner. Det har dock varit svårt att kartlägga e-förtroendets påverkan på användbarheten och vilka av kundrecensionens egenskaper som är användbara eftersom den tidigare forskningens resultat varit delvis inkonsekvent. Syftet med denna studie har varit att förstå förhållandet m
1. Conservation biology has traditionally neglected evolutionary processes, which are however fundamental in both the emergence and maintenance of biodiversity. Understanding adaptation can further allow conservationist to make predictions for species responses to changing environments which are vulnerable to climate change, such as mountain areas. 2. The size of a population is often important f
