Numerical model development and analysis of a drop-on-demand inkjet application

The jet breakup and the potential occurrence of satellite droplets play a crucial role in the print quality of drop-on-demand (DOD) systems. This thesis focuses on developing a numerical model to simulate droplet formation utilizing the volume-of-fluid (VOF) method. A particular focus is on the occurrence of satellite droplets and how different fluid properties influence the jetting behaviour. The

Robotised Guard Tours in Security Systems

With the growing market for enhanced security combined with recent advancements in robotic technology, the possibility of integrating these two fields is of considerable interest. While traditional surveillance relies on mounted cameras and scheduled guard tours by humans, the next step would be to use a robot to complement a person in such systems. This project explores the integration of autonom

Municipalities’ role in regional development: Navigating subsidiarity, place-based approaches, and geographical variation.

Even though place is associated with the local, place-based policy approaches target the regional level of government. Addressing this conundrum, this paper focuses on the local level studying municipalities’ regional development work in different types of regions in three Nordic countries. Through a comparative study across regional and national contexts, the paper identifies the need to clarify

Highly versatile, two-color setup for high-order harmonic generation using spatial light modulators

We present a novel, interferometric, two-color, high-order harmonic generation setup based on a turn-key Ytterbium-doped femtosecond laser source and its second harmonic. Each interferometer arm contains a spatial light modulator with individual capabilities to manipulate the spatial beam profiles and to stabilize the relative delay between the fundamental and the second harmonic. In addition, sep

TLE3 Is a Novel Fusion Partner of JAK2 in Myeloid/Lymphoid Neoplasm With Eosinophilia Responding to JAK2 Inhibition

Chromosomal rearrangements involving Janus kinase 2 (JAK2) are rare but recurrent findings in lymphoid or myeloid neoplasia. Detection of JAK2 fusion genes is important as patients with aberrantly activated JAK2 may benefit from treatment with tyrosine kinase inhibitors such as ruxolitinib. Here, we report a novel fusion gene between the transcriptional co-repressor-encoding gene transducin-like e

MULTISCALE COUPLINGS IN PROTOTYPE HYBRID DETERMINISTIC/STOCHASTIC SYSTEMS : PART I, DETERMINISTIC CLOSURES*

We introduce and study a class of model prototype hybrid systems comprised of a microscopic stochastic surface process modeling adsorption/desorption and/or surface diffusion of particles coupled to an ordinary differential equation (ODE) displaying bifurcations excited by a critical noise parameter. The models proposed here are caricatures of realistic systems arising in diverse applications rang

MULTISCALE COUPLINGS IN PROTOTYPE HYBRID DETERMINISTIC/STOCHASTIC SYSTEMS : PART II, STOCHASTIC CLOSURES

Couplings of microscopic stochastic models to deterministic macroscopic ordinary and partial differential equations are commonplace in numerous applications such as catalysis, deposition processes, polymeric flows, biological networks and parametrizations of tropical and open ocean convection. In this paper we continue our study of the class of prototype hybrid systems presented in [8]. These mode

Investigating Conspiracy Theoires : Introduction to the Special Issue

This introduction to this special issue of Inquiry looks at recent work in the philosophy of conspiracy theory theory. Looking at two related worries expressed in the wider conspiracy theory theory (the academic study of conspiracy theories) – the Problem of Conspiracy Theories and the Problem of Conspiracy Theorists – this special issue argues that recent work in the philosophy of conspiracy theo

Development of students’ concept images in analysis.

Students’ pre-knowledge and conceptual development in analysis were investigated at a teacher education program to reveal what pre-knowledge endured and how the students perceived the concepts a year after the course had ended. Questionnaires and interviews were used to collect data. Two students’ results are presented in more detail in the article. The study was cognitively framed with the influe

Students’ conceptions of limits, high achievers versus low achievers

Learning an advanced mathematical concept, limits of functions in this case, is not a linear development equal for all learners. Intentions and abilities influence students’ learning paths and results. Students’ learning developments of limits were studied in terms of concept images (Tall & Vinner, 1981) in the sense that their actions, such as problem solving and reasoning, were considered tr

Limits of functions as they developed through time and as students learn them today

This article compares first-year university students' development of the concept of limits to mathematicians' historical development of the concept. The aim was to find out if students perceive the notion as mathematicians of the past did, as understandings of the concept evolved. The results imply that there are some similarities—for example, the struggle with rigor and attainability. Knowledge o

Canaries of Democracy : The Role of Public Libraries in Times of Political Turmoil

Limits of functions - students solving tasks

This study was conducted to reveal how students at university level justify their solutions to tasks with various degrees of difficulty. The study is part of a larger study of students' concept formation of limits. The mathematical area is limits of functions. The study was carried out at a Swedish university at the first level of mathematics. The results are, however, applicable to other countrie

Limits of functions – how do students handle them?

This paper aims at formulating and analysing the development of 15 students in their creations of mental representations of limits of functions during a basic mathematics course at a Swedish university. Their concept images are sought via questionnaires and interviews. How do students respond to limits of functions? The data indicate that some students have incoherent representations, but they do

Limits of functions: Traces of students’ concept images

Students at a Swedish university were subjects in a study about learning limits of functions. The students' perceptions were investigated in terms of traces of concept images through interviews and problem solving. The results imply that most students' foundations were not sufficiently strong for them to understand the concept of limit well enough to be able to form coherent concept images. The tr
