Some numerical methods approximate the Jacobian using finite differences as part of their process. The finite difference method of approximation resembles the limit definition of the derivative. Since a computer cannot handle the mathematical concept of limits, a sufficiently small number has to be chosen as an increment. However, when the increments are chosen outside of certain acceptable ranges
Thermo Fisher Scientific manufacture automatic pipetting instruments for diagnostic tests. These tests are sensitive to abnormalities and changes in e.g. volume or density could potentially lead to less precision or other issues in the pipetting work flow. Utilizing data collected from a pressure sensor inside the pipette could be a way of automatically verifying different aspects related to the p
Electromagnetic compatibility (EMC) is a vital part of product development, and understanding the sources and causes of the emissions can facilitate tremendously in reaching compliance requirements and reduce the work needed for troubleshooting. At Axis Communications, where this thesis has taken place, the knowledge of EMC is an important part of their work and they aspire to improve further. Thi
År 2019 introducerade EU det så kallade visselblåsardirektivet. Direktivet tillkom för att komma till rätta med oegentligheter på den inre marknaden och stärka skyddsnivån för visselblåsare. Till följd av direktivets nya krav och bestämmelser behövde samtliga medlemsstater i EU ändra sin nationella lagstiftning på området. Enligt direktivet ska varje rättslig enhet med 50 eller fler arbetstagare hIn 2019, the EU introduced the so-called Whistleblower Directive. The directive was established to address misconduct in the internal market and strengthen the level of protection for whistleblowers. As a result of the directive's new regulations, all EU member states needed to amend their national legislation in this area. According to the directive, every legal entity with 50 or more employe
Concerto for Double Bass and Orchestra by Eduard Tubin is considered to be one of the most challenging pieces of the double bass repertoire as it is known to be a physically demanding work. It was written for double bass player Ludvig Juht who was a physically big built man and welcomed the technical challenges. This thesis aims to analyze these challenges of the piece for a player with smaller ph
I december 2023 kom HD:s avgörande i PFAS-målet, där frågan om förhöjd risk för framtida skada kan utgöra personskada ställdes på sin spets. HD uttalade att det strider mot det traditionella synsättet att klassa en ren förhöjd risk som en personskada. Höga halter av PFAS i blodet bedömdes däremot utgöra personskada eftersom de höga halterna innebär en beaktansvärd kroppslig försämring. UppställandIn December 2023, the Swedish Supreme Court ruled in the so called PFAS case, in which the question of whether an increased risk of future harm can constitute personal injury was put to the test. The court stated that it contradicts the traditional view to classify a mere increased risk as a personal injury. However, high levels of PFAS in the blood were deemed to constitute personal injury becaus
Voluntary Carbon Markets (VCM) have emerged with the intention of supporting decarbonisation and carbon dioxide removal solutions around the world. However, and despite a rapid growth, the motivations and preferences of the demand side to engage in with the VCM have not been thoroughly studied before. Iceland, the focus of this thesis, exemplifies this trend. To address this knowledge gap, this th
With his notion of original affirmation, Paul Ricoeur wishes to reinstate the primacy of being over nothingness, joy over anguish, and affirmation over negation. Having adopted the term from Jean Nabert, he draws from the tradition of French reflective philosophy to formulate his conception of the originally affirmative nature of existence. Ricoeur argues that positive values can be found in and t
This study aims to identify the most cost-effective and environmentally friendly retrofit solutions for enhancing the energy efficiency of second homes in Sweden. Second homes, often used intermittently throughout the year, represent a significant portion of residential energy use and carbon emissions. Therefore, optimizing energy consumption in these homes is critical for achieving national and g
This essay investigates the UN's legitimization of the MINUSTAH mission in Haiti and examines how colonial power hierarchies have been reproduced through the mission. By applying a critical discourse analysis (CDA) and Carol Bacchi's WPR-approach, the study analyzes resolutions 1542, 1576, and 1892 to identify the use of language that frames Haiti as an unstable and weak state, depicted as
Soil moisture (SM) is an essential climate variable that controls fundamental hydrological and climatic processes. Soil moisture products derived from microwave remote sensing often provide measurements at low spatial resolution and incomplete temporal records. This thesis presents a novel method for estimation soil moisture at both high spatial and temporal resolution by using a deep learning rec
Microgrids and distributed renewable energy have the potential to facilitate management and adaptation for climate change. While research on microgrids has been developing for the past decades, further studies are necessary to expand on business models and scenarios which lead to their successful commercialization and implementation. This study applied the business model canvas as an analytical fr
This thesis is a narrative analysis of four opinion-based texts associated to the symbolic meaning of the Øresund Bridge between Sweden and Denmark. All four texts were written in Swedish newspapers in connection to the twentieth anniversary of the inauguration of the bridge. The primary purpose of the study is identifying which symbolic narratives are formulated in the four texts and in the analy
The e-commerce sector in the modern, digital age is an increasingly important component of the global economy. For the European union, coping with this emerging market has meant regulatory challenges in several legislative areas, not least in the field of taxation. One of the most recent initiatives in removing obstacles for the e-commerce is the so-called VAT e-commerce package. The VAT e-commer
This thesis evaluates the effect of Chinese Foreign direct investment (FDI) on exports and imports for the five African countries: Angola, Nigeria, South Africa, Zambia and Zimbabwe using the gravitational model. The gravitational model will analyze how both inward FDI investments and Chinese investments impact import and export by using a sample of 166 partner countries over the period 2003-2012.
Anthropogenic pressure on coastal areas continues to increase, thus intensifying coastal erosion. Coastal monitoring programs are therefore essential to prevent severe ecosystem and economic consequences. Successful coastal monitoring schemes require highly accurate analysis-ready Digital surface models (DSMs) derived using the same workflow. Using a Unmanned Aerial Vehicle – Structure from motion
PFAS (per- and polyfluoroalkyl substances) are a group of synthetically manufactured chemicals contributing to environmental pollution. The largest point source of PFAS in Sweden is the usage of firefighting foam, and at MSB (Swedish Civil Contingencies Agency) Revinge, firefighting foam has frequently been used. Moreover, PFAS is known to accumulate in plants, and a Salix plant cultivation has be
Per- and polyfluoroalkyl substances (PFAS) include a large group of chemicals that has been used for many decades because of their mechanical and chemical stability. They owe these unique features due to the strong C-F bonds in their molecules. PFAS can be fully or partly fluorinated and the more fluorinated they get, the more persistent they become. They have been used in several industries such
