We study the Dirichlet problem for p-harmonic functions (and p-energy minimizers) in bounded domains in proper, pathconnected metric measure spaces equipped with a doubling measure and supporting a Poincare inequality. The Dirichlet problem has previously been solved for Sobolev type boundary data, and we extend this result and solve the problem for all continuous boundary data. We study the regul
High-order laser guide star performance for the Euro50 telescope is analyzed. Focus anisoplanatism residual errors using multiple LGSs are obtained by numerical simulations. Results calculated for annual mean conditions at the La Palma site show that, considering only focus anisoplanatism, it will be possible to obtain a Strehl ratio of 0.72 similar to 0.82 at 2.2 mum using 13 LGSs. A Strehl ratio
We report on large-scale ah initio multiconfiguration Hartree-Fock calculations for the UV0.01 multiplet, 2s(2)2p(2)P(J)-2s2p(2 4) P-J', in N III. The resulting transition probabilities agree very well with recent semiempirical calculations, and the lifetimes for two of the three upper levels agree with experiments. The deviation for the third level is discussed. Comparisons made with the highest
In this paper a wave splitting technique is applied to a homogeneous Timoshenko beam. The purpose is to obtain a diagonal equation in terms of the split fields. These fields are calculated in the time domain from an appropriate set of boundary conditions. The fields along the beam are represented as a time convolution of Green functions with the excitation. The Green functions do not depend on the
The Bremmer series is used to reduce a complex scattering problem to a sequence of simpler single-scattering problems. In the Bremmer series, the wave equation is first decomposed into a coupled system of one-way wave equations. The system is then decoupled into a sequence of one-way wave equations with a fixed-point iteration. In this paper, a left-symbol representation of the decomposition opera
Evacuation models can be reliably used if they are sufficiently validated for the application in question (e.g. Fire Safety Engineering). To be useful, an evacuation model should therefore be an accurate enough representation of the real-world behaviour of evacuees. The scope of this work was to determine how accurately the model crowd:it (making use of the Optimal Steps Model) provides a represen
I detta arbete har en Minimum viable product (MVP) för en applikation utvecklats, som gör det säkrare att avveckla och ta bort endpoints för ett REST API. Tidigare arbete har visat att hanteringen av avvecklingen av endpoints i REST API:er är ett problem, där REST API:er inte följer protokoll för avveckling och borttagning. Applikationen är gjord för att tillhandahålla ett enkelt sätt att övervakaIn this thesis - a Minimum viable product (MVP) for an application aimed at making deprecation and removal of REST API endpoints safer - was developed. Previous work has shown that handling deprecations and removal of endpoints in REST APIs is a problem, with REST APIs not following deprecation-removal protocols nor giving the API consumers the information needed to properly update their software.
Understanding the sustainability concept: According to the UN World Commission on Environment,(Borowy, 2013) it is the balance between environment, economy, and equity. The development meets the needs of the present without compromising the ability of future generations to meet their own needs (Rauschmayer et al., 2012). Sustainability is integration of the environmental health, social equity, and
This report describes the research, conclusions, and result of my Master Degree thesis project in Industrial Design at Lund University. The thesis was completed during the spring semester of 2018. The work was carried out in collaboration with Trimble Geospatial in Danderyd, Sweden. The main purpose of this thesis was to explore the future methods of working with geospatial instruments - s
PFAS is a group of long-lasting chemicals with multiple known toxicological effects which has been found everywhere in nature. One of the possible source points of PFAS is via landfill through leachate leaving the area. It is therefore important to investigate and implementing remediation techniques to reduce the contamination risk. This thesis focuses on two components, first a literature study w
Microfluidic devices have so far not seen widespread use, even though they could potentially be cheaper, better and faster than traditional methods. A possible reason for this is the lack of a middle step between one-of-a-kind experimental devices and cheap mass produced devices. With ongoing improvements in resolution it is starting to look possible that 3D-printing will fill this role. This the
Purpose: To explore why brands lose control over their identity due to internal actions or lack of actions when needed. The paper examines the key elements brands should focus on internally to prevent brand identity erosion which can negatively impact brand performance. Methodology: This paper explains the relevance of brand identity by a literature review and further builds on fundamental causes
Modern medicine is rapidly evolving toward personalized treatments, where therapies are tailored to an individual’s genetic profile. This shift is driven by the promise of pharmacogenomics, which aims to match patients with the most effective medications based on their unique biological makeup. As a result, biotherapeutics made from biological sources like proteins, peptides, and antibodies are be
This thesis investigates the creation and assessment of a Federated Learning (FL) system which improves real-time object recognition for visually-impaired applications through embedded AI and edge computing. The research divides into two distinct sections. The initial phase of the FL validation used a CNN trained on the MNIST dataset to allow controlled testing of model updates and communication b
Characterising the performance of ICs is a daunting task. With every year that passes, transistor technology keeps advancing and reducing in size. We are at a moment where, due to working with sub-90nm processes, it is not possible to have complete control over the manufacturing of the chips on the silicon wafers. It is mandatory to characterise the behaviour of each transistor using statistics, n
This thesis explores a range of control algorithms for multimodal acoustophoresis, the process of manipulating particles in a fluid by simultaneously using several acoustic modes. The aim of the algorithms is to precisely guide particle trajectories in acoustofluidic systems, motivated by the demand for non-invasive, scalable manipulation techniques in biomedical applications such as single-cell a
