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
This research analyzes the climate adaptation strategy of Copenhagen, focusing on cloudburst (rain-based) flooding and the use of infrastructure to mitigate damage. This strategy is analyzed through document analysis and structured interviews, using a theoretical framework of political ecology and urban green assemblages. This framework focuses analysis on the role of actors (human and non-human)
This master thesis analyses the effectiveness of smart beta strategies in improving the returns of index funds within the Nordic and Baltic regions. The study employs a mixed-method approach, combining qualitative literature review with quantitative empirical analysis of historical market data, focusing on key stock indices in Sweden, Denmark, Finland, Iceland, Norway, Lithuania, Latvia and Estoni
Ultrasound optical tomography is a medical imaging modality that combines ultrasound and light to improve the low resolution of optical imaging caused by scattering in tissue. Photons passing through an ultrasound pulse have a probability of being frequency shifted. By filtering out these photons and analysing them, images with optical contrast and ultrasound resolution can be obtained. In this t
This thesis considers solitary standing wave solutions to the Davey-Stewart-son equation, which is a model for surface waves on a body of water in three dimensions. In a special case, the Davey-Stewartson equation is reduced to the well-known non-linear Schrödinger equation with cubic power which is known to have a countable familiy of radial standing waves. One of the aims of this thesis is to in
Purpose – The purpose of this study is to uncover what motivational factors exists for companies to use co-creational methods. It also aims to recognize what beneficial factors can come from using these methods. The restriction of using social media depending on industry or size of company will be reflected upon. The main research question is “What motivates companies to use customer co-creation a
The yield curve of a collection of debt contracts describes the yield of the debt contract as a function of the length-to-maturity of the contract. It turns out that these yield curves provide useful insight about the economy as a whole and can, for example, be used to predict short-term economic downturns. Therefore, it is of utmost importance that financial analysts and decision-makers are able
In recent years, with corporate scandals and the global financial crisis there is continuous attention in the area of corporate governance which is the new concept in corporate world these days. It is seen as a moral duty and includes supporting the conformity to law and showing ethical guide. Corporate Governance is seen as a significant tool as firms’ financial performance when investors take an
Safety, privacy and comfort are elements that need to be improved on Swedish shelters. Since several homeless individuals often share bedrooms, it is not uncommon for them to be exposed to violence, harassment and theft or a generally disturbing environment during their stay. These are all contributing factors to an increased difficulty in getting out of homelessness. Enfold is a flexible w
Title: Good CEO Hunting; A study of a CEOs effect on innovation Seminar date: 17/01/2020 Course: FEKH19, Degree Project Undergraduate level, Business Administration, 15 ECTS-cr Authors: Camilla Eljuri Nylander, Julia Bergsten, Nicolina Hintze, Tor Enander Advisor: Devrim Göktepe-Hultén Keywords: Innovation, R&D, agency-theory, CEO, shareholders, RDI Purpose: The purpose of the study aims to ex
Tidigare forskning visade på att ledarskapsstilarna i CPE-modellen (Change-, Production- & Employee-centered leadership) är olika effektiva. Annan forskning visade att tidigare prestationer har en positiv korrelation till collective efficacy. Sambandet mellan CPE-modellen och collective efficacy inom idrottslag har däremot inte undersökts. Studiens frågeställning var därför att undersöka hur dPrevious research showed that the three leadership styles in the CPE-model (Change-, Production- & Employee-centered leadership) varies in efficiency. Further research showed that prior performances has a positive correlation with collective efficacy. The relationship between the CPE-model and collective efficacy, however has not been researched. This study, therefore, aimed at answering wheth
This thesis covers established procedures for the successful and attempted immobilization of lipases and phospholipases to various hydrophobic support materials, utilizing a rotating bed reactor, magnetic stirrer and tube-rotator. The design of a robust platform was established with great instrumental knowledge and proper conditioning for the creation of efficient immobilizations and activity assa
Highly glazed spaces are continuously increasing in popularity due to architectural attractiveness. However, increased use of glass often jeopardizes thermal comfort in several ways and problem of overheating is one of them. A way to face this problem is to appropriately use solar control mechanisms. However, a proper selection of solar control mechanisms from an early design stage is a complex ta
The main objective of this thesis is to present the article "An estimate of the condition number of a matrix", written by Cline et.al., which describes an algorithm for obtaining a reliable order of magnitude estimate of the condition number of a matrix in O(n^2) operations. In addition, the thesis introduces an iterative process for estimating the condition number in the 2-norm with arb
