For variable-frequency drives, the most common way to apply the desired power to an electrical motor is using PWM modulated signals. Due to high-frequency components, those signals give rise to reflections in the motor cables, radiated noise around the cables and acoustic noise in the motor. In order to avoid those problems, NFO Drives AB develops and produces an alternative to PWM modulation call
The debt equity bias refers to the discrimination between debt and equity finance. This discrimination is problematic since it distorts companies’ decisions and increases systemic risk. The European Commission has recommended Sweden to eliminate or reduce the bias and the Swedish Ministry of Finance has gathered a committee to investigate possible solutions. Sørensen (2010) suggested that Sweden w
Increasing demand for lower fuel consumption increases the importance of a higher total energy efficiency in trucks. Since the efficiency of a modern diesel engine is in the range of 40 %, large amounts of waste heat are produced. Recovering this energy can be done with thermoelectric generators. However, these generators’ open load voltage and internal resistance are temperature dependant, which
If adequately adapted, different sources of Lock-in provide new opportunities for companies on mature markets. Neglecting the importance of creating Lock-in in win-win situations could possibly make them victims of their external environment.
Large companies in today’s business environment are to a great extent depending on their credit score by rating institutes like Moody’s and Standard & Poor’s. There is however indications that these big institutes are not always rating companies accurately. This is why this thesis aims at developing a new credit rating model, CRITA-Score, with the objective of determining a company’s financial
This thesis deals with the vital issue of empowerment in development work and development projects, a multimillion dollar enterprise which engages donors,governmental agencies and governments. More specifically the thesis deals with a development intervention in education as social policy in Uruguay, investigated as a case study. The methodological intention is to present the voices of the subject
Lifelong Learning (LLL) involves the formal and informal education and learning of individuals and by extension society in a bid to function efficiently in today’s knowledge world. This Learning is not limited by age, race, or other susceptible circumstances; it is instead encouraged and seen in the contexts of adult learning, continuing learning, and work/ professional learning. By de-facto, it i
This paper examines the emergence of gender-neutral clothing, particularly during the period of 2015-2016 when there was a notable increase in interest surrounding the concepts of gender-neutrality and androgyny in fashion. The objective of this paper is to contribute new research to the field, as there is a lack of specific studies on gender-neutral clothing. To achieve this, the paper conducts i
This study evaluates the protection of fundamental rights within the liability framework of Article 17 of the CDSM Directive. The analysis is conducted under the questions: what are the defining features of the new liability framework of Article 17 CDSMD and its relation to fundamental rights? How has the implementation process of Article 17 affected the balance between fundamental rights? And fin
Intranasal drug delivery is a practical and accessible method for treating localized symptoms as well as achieving systemic drug absorption. The approach takes advantage of the permeability, vascularization, and limited enzymatic activity of nasal tissue, leading to enhanced drug absorption. Moreover, drugs can bypass the blood-brain barrier and directly reach the brain through the olfactory route
In tablet manufacturing, the addition of lubricant to the formulation is of high importance as it ensures smooth compression and ejection of tablets and thereby tablet quality. This study focused on lubrication of tablet formulation using magnesium stearate (MgSt) as a lubricant and microcrystalline cellulose (MCC) as bulk material. Powder blends were analysed to investigate whether an effect of v
Andelen äldre vuxna växer stadigt världen över. År 2030 beräknas en av sex personer i världen att vara 60 år eller äldre. Denna demografiska förändring innebär stora utmaningar för många länder. Bland annat att säkerställa att dagens snabbt växande tekniska utveckling tillgodoser behoven hos äldre vuxna. Flygindustrin är en av de industrier där det går att se en ökning av äldre vuxna bland passageThe demographic group of older adults is growing significantly worldwide. It is predicted that by 2030, one in six people in the world will be aged 60 years or older. This demographic shift presents major challenges for many countries to ensure that the fast-growing technology developments are ready to fulfil the needs of older adults. The flight industry is one of the industries that experience a
Epilepsy affects a significant portion of people worldwide and still requires alternative treatments due to resistance to anti-seizure medications. Gene therapy offers a promising alternative with several targets already established. Of these, glial cell line-derived neurotrophic factor (GDNF) and its receptor GFR⍺1 are well recognised for their roles in enhancing inhibitory signalling and support
The Corporate Sustainability Due Diligence Directive represents a significant step in the development of sustainability due diligence, with the potential to improve the human rights and environmental impacts of corporations and their supply chains. Although some companies have already begun enhancing their sustainability due diligence in light of the directive, the process is hindered by numerous
Sea ice is strongly impacted by global warming, and its decline further alters the global climate. Climate models are important tools for examining those future sea ice changes and the interaction of sea ice with other Earth system components such as the atmosphere and the ocean. Typically, these components are simulated with separate codes. The interaction between these components is typically mo
Ever since the end of the second world war, Europe has been lagging behind the United States in rocket development. In particular in the last 10 years, the technological gap and American competitive advantage have grown thanks to SpaceX’s development of reusable launch vehicles. A key enabler for the reusability of booster stages is precise rocket engine control. This thesis addresses the objectiv
This thesis investigates probing antennas within a small shielded test enclosure for IoT, Internet of Things, products for the detection of manufacturing deviations. The small enclosure forces the transmitter and receiver to be in the near-field. Shielding of the enclosure additionally generates a multipath environment, which becomes sensitive to displacements of objects such as wires or metallic
In response to the escalating threat of climate change, carbon capture and storage have gained increasing attention as an important component in mitigating the global carbon dioxide emissions. Substantial research efforts have focused on enhancing the energy efficiency and availability of these technologies. At the Department of Chemical Engineering at Lund University, research is being carried ou
Amelogenin is a protein which has been found to have many interesting properties. Its biological function is a key part in organizing the crystals of the enamel and it has been found to have a clinical use for periodontal regeneration. Its self-assembling properties also makes amelogenin a suitable material for the fabrication of biomaterials. The aim of this project is to investigate the possibil
This paper critically examines Rwanda’s Gender Strategy for the Mining Sector through the lenses of Bacchi’s What is the Problem Represented to be (WPR) approach and feminist political ecology (FPE) concepts. Against the backdrop of Rwanda’s post-genocide development journey, the study investigates how gender (in)equality is problematised, (re)presented, and promoted within the context of res
