The Single Molecule Spectroscopy Group at the department of Chemical Physics in the Chemical Centre of Lund University conducts research involving spectroscopy on single molecules of organic dyes. Fluorescence microscopy using a wide-field scheme has been used and such a scheme has many advantages such as full image capture at once when using a high sensitivity CCD or CMOS camera. Using different
The aim of this research paper is to explore how, and to what extent, the WIPO Marrakesh Treaty addresses the issue of restricted access to copyrighted materials by persons with visual impairments while securing legitimate interests and human rights of the central stakeholders; specifically, copyright rightholders and persons with visual impairments. In doing so, the focus centres on the compromis
This master thesis work consists of the development of new hardware and software for the control box of an azimuthal guidance system used by aircrafts during the approach to the runway. The thesis work was done at Safegate International AB as a project running along the usual development projects. When designing electronics to be used on an airfield there are a lot of regulations and standards t
This thesis explores various aspects of urban design and societal factors that contribute to creating child-friendly environments. The study begins by examining child-friendly design, emphasizing the significance of considering children’s needs in urban planning. Following this, a city-wide analysis of Reykjavík is conducted, exploring the swimming pool culture, the preschool and school system, an
Forensic sexual assault samples typically contain a mixture of a small quantity of sperm cells and a high quantity of epithelial cells. This relationship complicates the generation of a DNA profile, which prompts the need for differential lysis and extraction of the DNA. Differential extraction is a lengthy method that includes multiple tube transfers and requires a purification step. Amicon Ultra
The building sector contributes to one-fifth of Sweden’s total greenhouse gas emissions (GHG) and consumes 40 % of the final energy consumption. To achieve the climate goals set by the Swedish government, the building sector requires rapid development to reduce its climate impact. The climate impact of buildings comes from two types of energy throughout the building's lifecycle: operational an
Computer vision is on the cusp of revolutionizing several different markets through its applications. One such market is that of fitness and exercise. Advagym, Sony's connected gym solution is currently employing IoT solutions to track exercises in a gym environment. Together with Sony's R\&D Center Lund Laboratory's computer vision- and machine learning-equipped tracking system -
This thesis studied methods of improving a background model for a data processing pipeline of LiDAR point clouds. For this, two main approaches were evaluated. The first was to implement and compare three different models for detecting ground in a point cloud. These were based on more classical modeling approaches. The second was to use Deep Learning for semantic segmentation of point clouds and t
The EU-US Privacy Shield Decision on data transfers between the EU and the US was found invalid by the CJEU Schrems II ruling on 16 July 2020. After Schrems II, discussions among scholars and practitioners on legal challenges of international data transfers resulting from the case has gained much tension during the past years. Given the significant amount of data that flows between organizations a
The rehabilitation techniques currently available for patients who suffer from injury to the ulnar or median nerve tends to give suboptimal results. Typically, adults who are operated due to a complete transection of the median or ulnar nerve never regain normal sensibility in the injured hand leading to severe limitations in terms of hand function. One of the biggest challenges in sensory rehabil
Resource consumption is becoming increasingly scarce with an increase in the global population. Due to the increased resource consumption, the current linear economy model is unsustainable in the way it operates. The limitations of the linear economic model have been at the forefront to aspire circular economy in practice. Numerous factors have identified the need for the circular economy to emerg
The sustainable production and consumption of foods is gaining traction and globally, it is believed that there is nutritional transitional taking place from animal-based protein to plant-based protein. Product requirements, supply chain conditions, and consumption patterns for animal-based proteins and plant-based proteins will vary. This ensures that the packaging of plant-based foods must now m
Canada is one of the only nations in the world that offers universal health coverage that excludes outpatient prescription drug services. This means that citizens may find out their diagnosis free of charge, but must incur out-of-pocket expenses for prescription drugs dispensed outside of hospitals. This paper examines the prevalence of prescription drug coverage in Canada across various socioecon
Background and purpose: During radiotherapy, rectal cancer patients show inter-fractional internal motion that effects the delivered dose distribution. The purpose of this work is to study I) the inter-fractional bladder volume change, II) the effect of bladder volume change on bowel dose distribution, III) the effect of bladder optimization on the relationship between bladder volume and bowel dos
Over the last decade, financial disclosure and its impact on equity markets has increasingly become an area of interest. Firms suffering from poor operating performance have been shown to disclose bias earnings estimates as a means of evading negative market reactions. In this thesis, we attempt to discern whether managers purposefully bias their earnings estimates in periods of credit quality det
The interest of this research lies in the nexus between the state and the individual in providing social care for people searching asylum in Finland. The study explores the experiences of host families involved in offering home accommodation for asylum seekers. More specifically, it aims to understand the subjective role that host families assign to themselves when providing social care for this t
This thesis presents a comparison between implementations of the inverse square root function, using two approximation algorithms; Harmonized Parabolic Synthesis and the Newton-Raphson Method. The input is a 15 bit fixed-point number, the range of which is selected so that the implementation is suitable for use as a block implementing the inverse square root for floating-point numbers, and the des
Background. The objective was to determine how postmenopausal bleeding (PMB) is managed in Sweden today, and to relate the findings to a new evidence-based algorithm for the management of PMB. Methods. A questionnaire regarding the role of ultrasound and the use of different endometrial biopsy methods in the management of PMB was sent to all 61 gynecologic departments in Sweden. Results. Fifty-n
A study to determine and compare the sensitivities and specificities of the comparative cervical tuberculin (CCT) and gamma-interferon (IFN-gamma) tests for the diagnosis of bovine tuberculosis was conducted on 30 zebu oxen. The results of the tests were compared with the presence of acid-fast bacilli found by bacteriological culturing and histopathological examinations. The sensitivity and specif
