This master thesis report describes a product development process with the aim to create a construction which ensures an easier installation by replacing screws with other alternative assembly methods. The project has been performed at Axis Communications AB, which is the market leading company in network cameras. A previous project called Rocky provided the idea of an excenter lock compressing an
A growing problem in many cities is that the traffic demand fluctuates heavily during the day and that it grows larger as the years go by. This calls for, and the technology to easier measure traffic enables, more efficient traffic light controls that can handle a greater traffic demand but also be adaptive. Centralised control of traffic light might, even though it can be both adaptive and effici
Syfte: Syftet med arbetet var att undersöka hur jag som sångare upplever instudering och interpretation av två nyskrivna stycken beroende på hur involverad jag är i tonsättarens skrivandeprocess. Hur påverkas min instudering och interpretation av min involvering i tonsättarens kreativa process, och vilka skillnader upplever jag i förhållande till min egen inblandning i styckets uppkomst? Metod: TvAim: The aim of this study was to examine how I as a singer experience the studies and interpretation of two newly written pieces depending on how involved I am in the composer’s process of writing. How does my involvement in the composer’s creative process affect my studying and interpretation and what differences do I experience in relation to my own involvement in the making of the piece? Metho
ABSTRACT Author: Göran Hjertstrand Title: The difficult task – a study of experiences among public sector executives in ending employments [translated title] Supervisor: Charlotta Zettervall Assessor: Agneta Hedblom The purpose of this study was to examine experiences among public sector executives in ending employments. The study was based on semi structured interviews with five health and
Den här uppsatsen handlar om biståndshandläggare och hur mötet med brukaren går till i samband med kundval inom äldreomsorgen. Kundval innebär att brukaren, efter att ha blivit beviljad hemtjänstinsatser, själv får välja sin utförare. Med införandet av lagen om valfrihetssystem (2008:962) och ett stimulansbidrag från den svenska regeringen blir det allt vanligare med kundvalssystem i Sverige. BistThis essay is about social workers and how the meeting with the client goes in connection to customer-choice within the elderly care. Customer-choice means that after the client has been granted home care, the client is allowed to choose which provider to use. With the introduction of the act on free choice systems (2008: 962) and a stimulus contribution from the Swedish government, customer-choic
The goal of this thesis work is to describe the methods used and perform comprehensive testing of the Double-Sided Silicon-Strip Detectors (DSSD) prior to their implementation in the Lund-York-Cologne CAlorimeter (LYCCA) detector. In the framework of this project, the DSSD characterisation was carried out to ensure specification compliance prior to their "in-kind contribution" delivery t
In the hardware development space, field programmable gate arrays (FPGAs) are in a unique position as a result of their in-field re-programmability. In contrast to the traditional design process of integrated circuits, FPGAs allow iterative de- velopment workflows closely resembling software development’s sprint-based pro- totyping. For this to work, efficient workflows for verification are key. V
Speech has become an increasingly important source of non-invasive information for Parkinson's disease detection, but much existing work still relies on sustained vowels. This thesis investigates whether carefully represented continuous speech can provide added predictive value over a strong sustained-vowel benchmark. Using the NeuroVoz corpus, sustained-vowel recordings were first used to est
The adolescent experience has over the last twenty years differed immensely from earlier generations. Generation Z, born somewhere between 1995 and 2010, are what some would call ‘digital natives’, being the very first children to be brought up in a digital advanced world with easy access to information and inspiration through constant connection to the world wide web. This research draws in parti
In evaluating the effectiveness of a road safety treatment, the regression to the mean phenomenon is a cause for concern because of a possible overestimation of benefits. Therefore, Bayesian approaches are usually suggested as the most appropriate methodologies for before—after studies as they account for regression to the mean effects. The empirical Bayes (EB) methodology examines the estimation
OBJECTIVES: To investigate the experiences of a digital management programme for hip and knee osteoarthritis (OA), including education and exercises as well as an option to chat with an assigned physical therapist for feedback, questions and support.SETTING: This study was conducted at a regional hospital in the southern part of Sweden.METHODS: Nineteen patients (10 women), median age of 66 (q1-q3
Purpose – The purpose of this paper is to increase understanding of the use of standards and modularity for improving responsiveness in the humanitarian context. Design/methodology/approach – Based on a conceptual framework and a systematic literature review, the authors conducted a longitudinal, explorative case on the Emergency Response Unit (ERU) concept in the International Federation of Red C
Given many recent advanced embedding models, selecting pre-trained word representation (ie, word embedding) models best fit for a specific downstream NLP task is non-trivial. In this paper, we propose a systematic approach to extracting, evaluating, and visualizing multiple sets of pre-trained word embed-dings to determine which embeddings should be used in a downstream task. First, for extraction
Cross-laminated timber (CLT) is increasingly used for construction of multi-storey buildings. However, ensuring satisfactory vibro-acoustic performance, particularly in the low-frequency range (typically below 200 Hz), remains a significant challenge, often necessitating add-on solutions such as floating floors. In this study, the aim was to investigate how vibration levels for CLT panels can be r
Coking is a common catalyst deactivation route in industrial processes involving carbonaceous species. While coking is easy to diagnose, this is often performed by bulk analysis. Understanding specific symptoms such as pore blockage and obstruction of active sites is especially challenging for technical catalysts and requires a spatially-resolved approach. Here a combination of ptychographic X-ray
Recent developments in computer graphics and hardware technology enable easy access to virtual reality headsets along with integrated eye trackers, leading to mass usage of such devices. The immersive experience provided by virtual reality and the possibility to control environmental factors in virtual setups may soon help to create realistic digital alternatives to conventional classrooms. The im
The success of future Internet of Things (IoT) depends on, among the other things, developing energy-effcient communication techniques that can enable information exchange among billions of IoT devices with ultra-low/zero power consumption requirements. Ambient backscatter communications is an emerging technology, which utilizes the ambient Radio Frequency (RF) signal as the carrier to reduce the
The increasing use of 5G networks and their application in critical services makes them vulnerable to Distributed Denial of Service (DDoS) attacks. This thesis investigates the detection and mitigation of DDoS attacks in 5G networks using machine learning (ML) methods. In particular, it analyses two exciting convolutional neural network (CNN)-based models: the LUCID model and the Mohak model, and
