With modern day interest to continue the reduction of harmful emissions and improve the efficiency of combustion devices, the need to further improve upon accuracy and ability to describe combustive processes is of high value. Nowadays, multiple capable point (0D) and two-dimensional measurement (2D) techniques exist for flame investigation, however as combustion nearly always is a three-dimension
The accuracy and portability of depth cameras have increased by a lot in recent years, which allows for advanced 3D scanning of the environment for robotic applications. In this thesis we have developed a system that uses a depth camera mounted on a robot arm to identify and localize arbitrary objects, and give hints on how to move the camera to get better localization results. The system works by
Adaptation of modern Unmanned Aerial Vehicle (UAV) and multispectral sensor technology in agriculture can enhance the capacity to accurately monitor crops. But these technologies come with its own set of challenges. The major challenge is the understanding of radiometric distortions, which is particularly important while comparing data over different lighting conditions. The study developed and as
CellaVision develops automated microscopy for blood analysis. Their products can pre-classify 19 different types of white blood cells and support the medical technologist performing the final classification. CellaVision provides reference cells. The reference cells are a fixed set of cells handpicked by a technologist, chosen to be typical for that specific class. The reference cells are static, i
Antalet personer som lever med en kronisk sjukdom ökar, detta som en konsekvens av bland annat en snabbt ökande äldre befolkning. Kroniska sjukdomar orsakar inte bara mänskligt lidande, utan är också en ekonomisk börda för samhället. För att lindra lidandet och minska kostnaderna kopplade till kroniska sjukdomar kan användandet av digitala hälsotjänster vara en möjlighet. För närvarande är förväntThe amount of people living with chronic diseases is increasing. Chronic diseases do not only induce human suffering, it is also an economic burden on society. To ease the suffering and reduce the costs connected to chronic diseases, the usage of digital health services might be a possibility. Currently, the expectations on such services are high, but not met. To better meet the expectations, this
This paper examines how worries about war affect the political participation of women and men in Ukraine. The analysis is based on secondary data from the seventh wave of the World Values Survey 2017-2020. By constructing linear regressions, I examined whether there is a correlation between the worries about the war and the political activity of women and men in Ukraine. This allowed us to see how
The objective of this thesis has been to improve the camera controls of a fixed-wing drone to be used in maritime search-and-rescue operations by the Swedish Sea Rescue Society (SSRS). A gimbal control interface (GCI) has been implemented that displays the video feed of the drone camera while taking control inputs from a joystick that moves its view in real-time. In the thesis, the GCI has been
Den ökande andelen variabla förnybara energikällor i det svenska elsystemet har medfört ett växande behov av flexibilitet och balanstjänster. Batterienergilagringssystem betraktas som en nyckelteknik för att möta dessa behov, men deras ekonomiska lönsamhet är i hög grad beroende av marknadens utformning, geografisk placering samt vald operativ strategi. Syftet med detta examensarbete är att analysThe increasing share of variable renewable energy sources in the Swedish power system has led to growing demand for flexibility and balancing services. Battery energy storage systems (BESS) are widely regarded as a key technology to meet these needs, yet their economic viability depends strongly on market design, geographical location, and operational strategy. This thesis assesses the revenue pot
The thesis assesses the role of grassroots organisations in climate action through sustainable food practices, focusing on social innovation, collective learning, community-building and local resilience inside the city of Lund, in the Skåne region of southern Sweden. It intends to understand how local groups, combining practical knowledge with community-based innovations, collaborate to build a cu
Reliable six-degree-of-freedom pose estimation is a key requirement for autonomous on-orbit servicing (OOS), in which a robotic spacecraft performs tasks such as inspection, maintenance, and life extension of other satellites in orbit. However, generating trustworthy ground truth for algorithm development remains challenging. This thesis investigates calibration, sensor evaluation, and sensor fusi
The aim of this project is to discuss how designers can contribute to gender equality and female empowerment in craft-production industry. The study was done as a collaboration with the Indian organization Industree to study methods designers can use to assure that the economic/social balance in the value chain is fair. The organization works with craft-production as a means of generating income a
Spider silk is a highly attractive biomaterial with exceptional strength and versatility, offering potential applications across numerous industries. However, large-scale production remains a significant challenge. Harvesting silk directly from spiders has proven impractical, making recombinant protein production a promising alternative. Spider silk has been studied at Lund University for several
Architecture is often seen as the art of permanence, of creating structures meant to endure. But what happens when permanence is disrupted – when buildings fall into ruin or are dismantled? This thesis explores decay, reuse, and reassembly, challenging conventional preservation by embracing impermanence and unconventional outcomes. Set in the hills of Oltrepò Pavese in southern Lombardy, it focuse
Industrial society is the reason for the rising global ecological crisis, and companies are a primary contributor to this trend. To change this course, companies must transform along with society’s green transition. In the academic debate of economics and sustainability, various competing economic paradigms suggest how to steer society towards a sustainable transformation. Based on theoretical his
Size Exclusion Chromatography (SEC) is a crucial analytical tool employed by Novo Nordisk for the assessment of potential aggregation in active pharmaceutical ingredients (API) derived from peptides and protein biopharmaceuticals. This investigation focuses on SEC analyses conducted under denaturing conditions, utilizing Ultra High-Performance Liquid Chromatography (HULK) adapted columns. Intrigui
This thesis describes the development process of a digital tool that can be used by locksmiths to quickly and easily find the right components for repairing and replacing electronic locking mechanisms. The tool took the form of a mobile application and was developed in collaboration with Robust Ellåsning AB in Malmö, Sweden. The report describes an iterative, human-centered design process, from da
With the development of the global economy and human society, population growth and urbanization, water resources are becoming more and more important, and the monitoring of water resources is also crucial. Therefore, this article designed a system for monitoring PH level in water, and designed a wireless transmission system based on LoRa technology. According to the actual application requir
