During recent years, advancements in mobile technology have enabled the development of quadcopters and unmanned aerial vehicles (UAV) to the point where their size and maneuverability enable indoor flight. In such GPS-denied environments, accurate positioning is a challenge which poses difficulties during flight, navigation and landing. Such positioning systems exist, but are often expensive or re
This thesis studies a network game of heterogeneous and asymmetric public goods. Players allocate their wealth between private and public goods, benefiting from the public goods provisioned by their out-neighbors on the network graph. Utilities are given by a Cobb-Douglas function to capture substitutability and decreasing marginal returns. I prove that the game is well-behaved under a condition r
Production and patient safety requirements are high in pharmaceutical industries where standards are set accordingly and controlled by e.g. the U.S. Food and Drug Administration (FDA). It is crucial that these standards are met without compromising the fact that production must run as effectively as possible, i.e. achieve Overall Equipment Efficiency (OEE), for the pharmaceutical companies to deli
The present study concerns the implementation of a voluntary job rotation program for individual and organizational development. In order to increase participation in job rotation programs, it is crucial to understand the phenomenon of non-participation. Accordingly, the present study aims to (a) identify reasons for non-participation from an employee perspective and (b) uncover possible hindrance
Uppsatsen ämnar att, på ett djupare plan, synliggöra vad som kan upplevas ingå i polisens arbetsuppgifter utöver det praktiska arbetet. Hur upplever poliser i yttre tjänst relationen mellan polisrollens krav och personliga känslor? Hur hanterar poliser i yttre tjänst egna emotioner i tjänstgöring utifrån yrkesrollens krav? Hur påverkas poliserna av relationen mellan yrkesrollens krav och personlig
In an effort to curb climate change, the electric power system in many countries is transitioning from fossil fuels to more renewable power sources such as wind. At the same time, other countries are decommissioning their old nuclear power, and replacing it with wind power. When replacing synchronous machines with wind power the inertia in the system is decreased. If nothing is done about this the
Electrolytic capacitor components degrade when exposed to thermal stress which can cause failures in electrical devices. Several recent works have studied the lifetime of these components by using accelerated life testing. This work, however, takes a new approach by utilising vast amounts of temperature data and regression techniques. Axis Communications collects large amounts of non-personalised
New approaches in agriculture utilizing plant-growth promoting microorganisms have the potential to decrease our reliance on artificial fertilizers and pesticides, which is an evergrowing societal concern. Fungi of the genus Trichoderma are abundant in soils all over the world and can positively affect plant stress tolerance and yield. However, this growthpromoting effect is dependent on the plant
Development of a successful prophylactic or therapeutic treatment for active Tuberculosis (TB) has been hampered by the bacilli’s ability to evade, tolerate, subvert host immunity and persist in a hypoxic intracellular niche. Upon infection with M. tuberculosis (Mtb), there is an increased demand for metabolites by cells to respond to the robust immune activation, which is met with a shift of meta
Skolfrånvaro eller skolk är ett fenomen ofta kopplat till olika orsaker som stress, social exkludering, förlust av självförtroende och självkänsla samt även drogmissbruk, något som har långtgående konsekvenser för individen och i förlängningen samhället. Huvudintresset i denna studie var att hitta och förstå relationerna mellan global självkänsla och kompetensbaserad självkänsla (CBSE), skolfrånvaSchool absenteeism is today a worldwide phenomenon linked to a plethora of issues with long term consequences on both individuals and society, such as stress, social exclusion, loss of confidence and self-esteem and even drug abuse. This study investigates the interrelationship between global self-esteem and competence-based self-esteem (CBSE), absenteeism and academic performance as well as stres
Workplace health promotion has been gaining a lot of interest, as it could benefit both employees and organizations. Results and conclusions are, however, still ambiguous and there is not much known about how employees’ participation and perception affect positive work outcomes. The present research aims to examine the link between employees’ participation and perception of workplace health promot
Antarctic krill, Euphausia superba, a polar ocean specialist, thrives in the Antarctic severe physical conditions. The krill life cycle consists of strategies that have enabled and supported the species’ dominance of the Antarctic Ocean. Sea Ice extent and duration creates condition that are crucial for survival of the Furcilia larvae. The species has flexibility to food resources and is omnivorou
In the age of ever-growing technological advancements, delegating some of the inherently human tasks to smart machines is becoming more and more common. The possibly new wave of industrialization – Industry 4.0 – is comprised of interconnected smart technologies that could automate parts of the production and decentralize the decision-making process. The associated efficiency has prompted business
Möjligheten att få studera medlemsminskningen i Svenska kyrkan har fångat mitt intresse, och utgör utgångspunkten för denna uppsats. Studiens syfte är att utforska olika förklaringar till medlemsminskningen. Den valda metoden för denna uppsats är kvalitativ istället för kvantitativ, då uppsatsämnet tjänar på att kunna belysas med mer detaljerade svar. Studiens upplägg har baserats på Svenska kyr
There is an urgent need for change within the garment sector as it continues to massively contribute to the climate crisis. This need for change has led to a growing interest in collaborative fashion consumption and its possibilities to support sustainable consumption within the garment sector. This research explores whether the two identified models of collaborative fashion consumption, business
This thesis explores the experiences of international and domestic higher education students in the U.S. during the 2020 COVID-19 pandemic. By using an Interpretative Phenomenological Analysis (IPA) approach the aim of the thesis, in the first place, is concerned with students’ experience during national and global lockdowns with social distancing and isolation and, secondly, with the structural c
