This thesis investigates few-body quantum rings, particularly in the study of ultracold bosonic gases and nanowire quantum dots. These systems are investigated numerically using exact diagonalization methods. This dissertation contains five chapters which develop numerical and theoretical background for understanding the few-body calculations and analysis contained in the four included papers: Pap

In this dissertation I examine the main scaling challenges in autonomous driving development, discussing recent advances in the field while contributing specific solutions to key bottlenecks. The first challenge is the reliance on human labor, particularly for annotations. Here we make two key contributions: new techniques to extract additional value from existing annotations through future predic

The archaic witch Circe from Greek mythology has been an enduring figure in history in Western literature and English-speaking cultures. The character has undergone multiple adaptations and is seemingly restricted to the archetype of a villainous femme fatale, symbolising the threat of wilderness and female sexuality. In Miller's novel Circe (2018), the character undergoes another transformati

Among several methods used to obtain ultra-high vacuum (UHV) for particles accelerators chambers, it stands out the internal coating with metallic films capable of absorbing gases, called NEG (non-evaporable getter). Usually these materials are constituted by elements of great chemical reactivity and solubility (such as Ti, Zr, and V), at room temperature for oxygen and other gases typically found

BACKGROUND: Cardiovascular, respiratory, and musculoskeletal disease are among the leading causes of disability in middle-aged and older people. Health and lifestyle factors in youth have known associations with cardiovascular or respiratory disease in adulthood, but largely unknown associations with musculoskeletal disease.METHODS AND FINDINGS: We included approximately 40,000 18-year-old Swedish

The installation of a second RF cavity in the UVX electron storage ring at the Brazilian Synchrotron Light Laboratory (LNLS) at the end of 2003 brought about longitudinal instabilities driven by one of the HOMs of the new cavity. Even though the operational difficulties related to these unstable modes were successfully overcome by means of a combination of cavity tuning (using temperature and plun

We describe recent efforts made at the Brazilian Synchrotron Light Source (LNLS) to improve beam orbit stability. The main driving force is the high positional stability required by some specific experiments and particularly by a high resolution undulator beamline which is being built at LNLS. Recent steps taken to improve orbit stability include the development of x-ray BPMs to measure the vertic

At the Istituto Nazionale di Fisica Nucleare – Laboratori Nazionali del Sud (INFN-LNS) the commissioning of the high intensity Proton Source for the European Spallation Source (PS-ESS) started some weeks ago. Beam stability at high current intensity is one of the most important parameter for the first steps of the ongoing commissioning. Commissioning plan and preliminary characterization are also

Contrary to the dominant perception of transnational adoption as an act of goodness, an increasing number of Korean adult adoptees in Denmark have raised critical voices about the political economy of transnational adoption since the mid-2000s. They have participated in the adoption debate not just as individuals, but through collective critiques and mobilisation. This article looks at the develop

This article examines the narratives associated with the “Shekou Model” in China’s development of the Hambantota International Port in Sri Lanka. Through a dual narrative analysis and policy evaluation approach utilizing official Chinese and Sri Lankan statements, it examines the motivations of the Chinese Communist Party and the China Merchants Group in “selling” the Shekou Model and how Sri Lank

Studien syftar till att undersöka hur de anställda inom en kunskapsintensiv organisation upplever effekterna som uppstår efter en förändring som är tänkt att främja autonomi. Studien positionerar sig om ramen för teorier kopplat till byråkrati, autonomi, chefskap & ledarskap. Studiens resultat visar att det paradoxalt nog uppstår ett behov av direktiv, chefskap och mer byråkratiska processer e

The goal of this master thesis was to identify an alternative to shaft encoders as means of achieving accurate motor velocity and position control for sliding door systems. While the company had previously explored methods like using backEMF, this thesis investigates counting voltage ripples during the commutation process in a brushed DC motor. During commutation, one or two pairs of commutator se
