Efterfrågan av bättre digitala läroverktyg har ökat de senaste åren, och fick en ytterligare höjning av Covid-19-pandemin. Många företag använder artificiell intelligens för att förbättra sina system, där ett användarfall är frågegenerering. Teknologin inom artificiell intelligens har dock avancerat så snabbt att andra forskningsområden inte har hunnit ikapp. Målet med denna uppsats - vilken är The demand for improved digital learning tools has increased over the recent years, and got an additional boost from the Covid-19-pandemic. Many companies use artificial intelligence to improve their systems, one use case being question generation. However, artificial intelligence technology has advanced so quickly that other research fields such as user experience has not been able to keep up.

Heart disease is one of the worldwide leading causes of death, and facilitating the work of physicians in this area is therefore of great importance. Imaging of the heart is one of many fields that is used for diagnosis and analysis of cardiac disease. Within this field, Magnetic Resonance Imaging (MRI) is a non-invasive technique that allows for acquisition of high quality images. Blood flow th

The Kolmården wild life park located in Sweden, asked for adevice to be used in their dolphinarium to enable the trainers to call individual dolphins. This is to be don eusing their signature whistle, which is unique for every animal. Since dolphins themselves are using their signature whistle to make contactbetween eachother, thehypothesis is that teaching them to understand thattheir own unique

For evaluation of specific antenna arrangements in wireless communication systems we need physical channel models that take into account the directional domain. Here we propose a practical approach to wireless channel modeling in, particularly, mobile communication systems, by using an assumption that the channel can be divided into separate parts or regions that can be treated and modeled individ

Resistivity imaging in combination with drill hole information is a powerful tool in geotechnical site investigations. Traditionally the resistivity data is inverted with a 2D smooth inversion algorithm, resulting in a minimum structure model. In the geological interpretation it can be difficult to determine sharp layer boundaries in these models. An additional parameterized inversion of resistivi

Purpose of the Study: This study describes a teaching innovation introduced into a retail course assignment. The purpose with the innovation was to increase students’ level of experiential learning by incorporating digital retail and collaborating with stakeholders. Method/Design: A course assignment allows students in the final semester of a Bachelor Program in Retail Management to develop a busi

Over the last decades Boolean satisfiability (SAT) solvers based on conflict-driven clause learning (CDCL) have developed to the point where they can handle formulas with millions of variables. Yet a deeper understanding of how these solvers can be so successful has remained elusive. In this work we shed light on CDCL performance by using theoretical benchmarks, which have the attractive features

OBJECTIVES: Infantile hemangiomas (IHs) are common; some cases require timely referral and treatment to prevent complications. We developed and validated a reliable instrument for timely and adequate referral of patients with IH to experts by nonexpert primary physicians. METHODS: In this multicenter, cross-sectional, observational study, we used a 3-stage process: (1) development of the Infantile

It is easy to get carried away with the rhetoric of solidarity. Rethinking solidarity aims to problematize the way that solidarity has been conceptualized and applied as a governing principle of EU asylum law and policy, in particular as a response to the 2015–2016 ‘refugee crisis’. Navigating through a family of ideas – from Aristotle’s philia, Christian agape, and Roman law to French solidarism,

In heterogeneous catalysis the reactions occur on the surface of a catalyst. To understand the reaction pathways, a detailed understanding on an atomic level is critical. However, the gas atmosphere surrounding the surface dictates the interaction between the surface and the gas. At low pressures this is often neglected, but as the community turns to higher pressures it becomes important to consid

The solid oxide fuel cell (SOFC) is an electrochemical device that converts the chemical energy present in reactant fuels into electrical energy and heat. Such conversion is given by the electrochemical reactions that occur inside the fuel cells when the reactant gases reach the so-called Three-phase Boundary (TPB). However, before the reactant gases can reach the TPBs, they have to pass through a

Introduction: Central venous access devices facilitate home treatment in boys with haemophilia. These are usually fully implanted lines, referred to as ports. Caregivers are taught to manage the port using sterile techniques and maintaining patency by flushing with saline or heparin solution. National and international guidelines for the home care of ports are lacking. Aim: To evaluate if infectio

Due to the ability to manipulate photons at nanoscale, plasmonics has become one of the most important branches in nanophotonics. The prerequisites for the technological application of plasmons include high confining ability (λ0/λp), low damping, and easy tunability. However, plasmons in typical plasmonic materials, i.e., noble metals, cannot satisfy these three requirements simultaneously and cau

Preliminary mobile was considered to be a device to make human connections easier. But today the consumption of this device has been evolved to a platform for gaming, web surfing and GPS-enabled application capabilities. Embedding GPS in handheld devices, altered them to significant trajectory data gathering facilities. Raw GPS trajectory data is a series of points which contains hidden informatio

Background: There has been a lack of a standardized protocol for collection of patient reported outcomes (PRO) and detection of and indication for psychological treatment in cleft care. The objectives of this paper was to translate Cleft Hearing Appearance and Speech Questionnaire (CHASQ) into eight European languages, to investigate whether levels of PRO in patients with cleft lip and/or cleft pa

The rheology of dense suspensions in the viscous regime can be characterized by the viscous number J and granular flows by the inertia number I, both relating the shear rate γ - to the confining pressure P. Furthermore, several works have shown that the rheology of suspensions and granular flows can be unified, and this unification is used to characterize suspensions with non-negligible particle i
