This thesis presents the design and schematic-level simulation of a highly linear mixer-first receiver front-end implemented in CMOS, targeting improved robustness against strong input signals. The proposed architecture employs a current-mode passive mixer directly loaded by a low-impedance transimpedance amplifier (TIA) in order to minimize the voltage swing at the mixer output and thereby enhanc
Developing high-temperature proton exchange membranes (HT-PEMs) that simultaneously achieve high proton conductivity, strong phosphoric acid (PA) retention, and long-term chemical stability remains a major challenge, particularly due to PA-induced plasticization and radical-induced oxidative degradation. Here, we develop a side-chain engineering strategy to decouple PA-binding sites from the polym
With approximately 94 percent of traffic accidents being caused by human error, improving driver behaviour has the potential to save lives. To encourage safer driving, Volvo Cars is developing a Safety Coach feature for their mobile application. However, pilot studies of a minimum viable product (MVP) indicated low user retention, suggesting the need for design elements that better support user en
Heavy rainfall and cloudbursts are expected to increase as a result of climate change, putting greater demands on sustainable stormwater management. This study investigated the possibilities and challenges perceived by Swedish municipalities and water and wastewater utilities in the implementation of sustainable stormwater solutions. Additionally, the study examines how the proposed expansion of t
PurposeIn the transformation to the circular economy, circular logistics nodes are becoming increasingly important to, for example, match supply and demand, coordinate flows, increase logistics efficiency and customer utility, and reduce environmental impact. The purpose of this study is to expand our theoretical understanding of the circular retail transformation and its implications for circular
The healthcare systems of today are facing large challenges, with increasing amounts of patients and overworked hospital staff. Prostate cancer and Alzheimer’s disease are two of the most prevalent diseases, with incidence numbers expected to rise over the coming decade. Medical imaging plays a central role in current diagnostic procedures for these diseases, enabling the potential use of machine-
Background and Objectives – Limbic-predominant age-related TDP-43 encephalopathy (LATE) is characterized by an amnestic- and limbic-predominant phenotype, which can mimic Alzheimer disease (AD). In a memory clinic cohort, we tested whether clinical criteria for LATE can detect a clinical profile of LATE that is distinct from AD.Methods – In this retrospective examination of a longitudinal memory c
The rise of solo living presents significant social and environmental challenges, particularly in high-income countries like Denmark where nearly half of households are single occupancy. This study explores the social dynamics driving the trend towards living alone through in-depth interviews with 23 individuals living alone in Denmark. Pathways to solo living include urban relocation, aging out o
This research was conducted to determine which areas in the Robat Turk watershed in Iran are sensitive to gully erosion, and to define the relationship between gully erosion and geo-environmental factors by two data mining techniques, namely, Random Forest (RF) and k-Nearest Neighbors (KNN). First, 242 gully locations we determined in field surveys and mapped in ArcGIS software. Then, twelve gully
As some insect groups are declining at alarming rates, accurate and automated insect monitoring is needed to prioritize habitats for conservation. The dual-band entomological Scheimpflug lidar technique is a promising candidate method for real-time insect monitoring: it allows the detection of thousands of flying insects per day at high temporal and spatial resolutions. The signals contain a pleth
How environmental and climate challenges that often evoke strong negative emotions are communicated and responded to is of great importance. These include forest fires, plastic pollution and flooding that can produce fear, sadness and powerlessness. Images are important to this communication, yet how these challenges are captured through visual communication tools and to what outcomes requires fur
Light extinction is widely used to study particles in sprays, soot-forming combustion, and multiphase reactive flows. However, quantitative interpretation of extinction signals remains challenging when particles have a sufficiently large scattering albedo, meaning that incident photons are scattered much more than they are absorbed. This is especially true when experiments involve large apertures
We present PyeLink and SyeLink, two complementary open-source Python tools for running eye-tracking experiments and parsing data from SR Research Ltd. EyeLink eye tracking hardware. PyeLink simplifies experiment creation through plug-and-play support for multiple display backends (Pygame, PsychoPy, Pyglet) while enabling two features not available in existing tools: recording data during calibrati
Title Factors for success : a study of school libraries at compulsory schools and how to integrate them in the education Abstract This Master's thesis aims to identify success factors for the integration of school libraries in the education. The search for factors are concentrated to three areas: control documents for the school and school library, the Principal and organisation and the col
Populärvetenskaplig sammanfattning: Geografiska informationssystem på internet är ett relativt nytt fenomen som främst har utvecklats från ett behov att distribuera geografisk data, dvs utbyte av digitala geografiska data och tillhörande tjänster. Men det är även ett kraftfullt verktyg för att presentera information på internet. Detta examensarbete i naturgeografi syftar till att skapa en webbaGIS on the Internet is a rather new phenomenon, which has evolved from the need of distributed geographical data. It is also a powerful tool for presenting information on the Internet. This master thesis aim to create a web based GIS application with information on lime spreading and the situation concerning acidification in the county of Kronoberg, Sweden. The web based GIS application will be us
Bakgrund/Frågeställning: Den nynazistiska grupperingen Nationalsocialistisk Front var i slutet av 1990-talet mycket aktiv i Karlskrona kommun i Blekinge. Kommunen svarade genom att lansera ett program man kallade "att visa demokratins muskler" för att bekämpa grupperingen. Detta arbete gick ut på att kommunen genom tillämpning av den befintliga lagstiftningen ville försvåra för nynaziste
The purpose of this essay ("Gateway to the Past. An archaeological quality controlled subject gateway as a resource for higher education in Lund") is to examine how a quality controlled subject gateway could increase the quality of the information supply for the Department of Archaeology and Ancient History at Lund University. The essay gives a brief background to subject gateways and al
