There is a lot of discussion going on how to adapt to the changing climatic conditions, especially in countries where financial resources are limited. The built environment has been identified as a key area of intervention. As disasters, such as typhoons, can devastate entire cities, it is essential that the most important buildings in these cities, the lifelines so to speak, are resilient and can
This thesis project investigates the topic of joint optimization for crest factor reduction and digital predistortion blocks, which are used for digital correction of analogue impairments in digital radio front ends. The work first investigates the effects of joint parameter variation of the above blocks on the global performance and computational cost of the digital chain, given reference CFR and
This thesis explores the provision of memorable digital cultural experiences (MDCEs) for young audiences, thereby addressing the existing gap in the literature concerning the experience economy, digitalization in the cultural sector, and memorability of experiences. Based on qualitative in-depth interviews, the research explores cultural consumption trends, uncovers factors contributing to the mem
The development of generic pharmaceuticals includes extensive data on equivalence with the reference listed drug is required by the European medicinal agency (EMA) and the North American equivalent. Equivalence must be proven for rheology, microstructure, and performance. This is a costly and time-consuming process. To reduce the costs, it is of interest to investigate if the release profile (perf
BACKGROUND. Early and accurate detection of infectious respiratory diseases like COVID-19 and tuberculosis (TB) plays a crucial role in effective management and the reduction of preventable mortality. However, molecular diagnostic tests for these infections are expensive and not easily implementable in resource-limited settings, which suffer the majority of the burden. Lung Ultrasound (LUS) presen
Meningsfull förändring har diskuterats i flera studier, med den återkommande frågan om hur den skulle kunna konceptualiseras och bedömas för att identifiera vad som utgör meningsfull förändring och var den uppstår. Tidigare studier har genomfört statistiska analyser baserade på traditionella betygsskalor (d.v.s. PHQ-9) för att bedöma meningsfull förändring. Det finns inga bevis för att tidigare stMeaningful change has been discussed in multiple studies, with the recurring question of how it could be conceptualized and assessed to identify what determines meaningful change and where it occurs. Previous studies have conducted statistical analyses based on traditional rating scales (i.e., the PHQ-9) to assess meaningful change. There is no evidence to be found of previous studies attempting t
With increasing pressure to get rid of the world’s dependence on fossil fuels to reach the world’s climate goals, the use of alternative fuels for propulsion are needed. This is a challenge for the maritime industry, where ferries have good properties to become renewable by the usage of batteries. Their routes are mostly fixed routes and with good infrastructure established at each stop, fully bat
Reco Port AB is a company that builds folding garage doors and is a part of the ASSA ABLOY group. Reco uses Styrofoam as insulation in their doors and their current solution of cutting the Styrofoam is using a plunge saw and a custom built table to hold the Styrofoam in place. The solution is not ergonomic and spreads a lot of debris of Styrofoam around the workstation. Due to this it was requeste
Today, most software systems are event-driven, meaning that code execution is triggered by events handled dynamically. A typical example is a graphical user interface, where a button click initiates a specific action. In contrast, classic automation systems rely on programmable logic controllers, which execute code periodically at fixed intervals. The purpose of this study is to compare periodic a
The existing Power Supply Unit (PSU) at Axis Communication contains a fully discrete solution that lacks flexibility for future updates. This research aims to address critical challenges by exploring methods to enhance speed, reduce PCB area, and introduce flexibility to the existing hardware solution. The approach involves replacing hardware functionalities within the control unit with software-c
Buildings of all types are increasingly becoming complex ‘systems of systems.’ They are subject to evolving societal objectives, new and innovative materials, and in many countries, regulatory ecosystems are having difficulty keeping pace with rapidly changing societal, environmental and technological changes. Two evolving objectives that are stimulating changes to buildings and communities are th
In this work, we consider the problem of localizing multiple signal sources based on time-difference of arrival (TDOA) measurements. In the blind setting, in which the source signals are not known, the localization task is challenging due to the data association problem. That is, it is not known which of the TDOA measurements correspond to the same source. Herein, we propose to perform joint local
Externally bonded reinforcement (EBR) was used to increase load bearing capacity of light weight aggregate concrete (LWA) masonry walls subjected to eccentric axial compression. Ladder type masonry reinforcement, high strength steel wire strips and glass fiber mesh were used for strengthening of eleven, 2.4 m high, 0.5 m long and 0.1 m thick walls. The reinforcement was applied on the dry wall sur
The ability to generate and control movement is essential for human interactions and overall well-being. Neuromuscular impairment caused by neurological injuries and diseases, such as stroke or limb amputation, severely limits the ability of affected individuals to interact with the surrounding environment, necessitating advanced strategies for rehabilitation and restoration of motor function. Vol
Although political governance guides education and research, there are options for researchers, educators and curators to act in the spirit of academic freedom. The deontological ethical guidelines stabilize the archaeological establishment no matter what kind of work. The utilitarian dimensions within archaeological research and higher education open up for critical thinking.Twisting and turning,
We introduce a novel method for extracting a fragmentation model directly from experimental data without requiring an explicit parametric form, called Histories and Observables for Monte-Carlo Event Reweighting (HOMER), consisting of three steps: the training of a classifier between simulation and data, the inference of single fragmentation weights, and the calculation of the weight for the full h
Indoor sensing is challenging because of the multi-bounce effect, spherical wavefront, and spatial nonstationarity (SNS) of the near-field effect. This paper addresses radio-based environment sensing considering these issues. Specifically, graph theory (GT) is used to model the multi-bounce propagation of the near field. In this manner, indoor reflectors/scatterers are modeled as vertices in a pro
