The goal of this master thesis was to identify an alternative to shaft encoders as means of achieving accurate motor velocity and position control for sliding door systems. While the company had previously explored methods like using backEMF, this thesis investigates counting voltage ripples during the commutation process in a brushed DC motor. During commutation, one or two pairs of commutator se
Min kandidatuppsats fokuserar på att analysera vilka möjligheter det finns att förena vinstsyftet enligt 3 kap. 3 § aktiebolagslagen med hållbarhet. Både hållbarhet och vinstsyfte är viktiga aspekter. Det är svårt att kombinera de två aspekterna i ett aktiebolag då vinstgenerering är det man strävar efter, detta kan leda till kollision med hållbarhetsaspekter. I det andra kapitlet ligger fokuset pMy bachelor's thesis focuses on analyzing the possibilities of reconciling the profit motive according to Chapter 3, Section 3 of the Swedish Companies Act with sustainability. Both sustainability and profit motive are important aspects. It is difficult to combine the two aspects in a limited liability company when profit generation is the aim, which can lead to a collision with sustainability
The purpose of this study is to examine how the capital structure in swedish listed firms changed during the Corona-crisis. The study focuses on the years 2017-2022 to compare before and during the crisis. The study also uses six control variables to capture changes in capital structure. To compare capital structure, the study uses three types of debt ratios, total, short and long term leverage. T
Syftet med denna uppsats är att utifrån ett referensobjekt undersöka hur broar med integrerade stöd grundlagda på stålrörspålar kan utformas för att uppfylla högt ställda deformationskrav för höghastighetståg. Användningen av integrerade stöd är stor i bland annat USA och England. De främsta fördelarna med integrerade stöd är att de innebär att broar kan utformas utan lager och fogar. Detta är fö
This research explores the impact of different capital financing strategies on the development of sustainable innovations within startups. Grounded in theories of Sustainable Business Model Innovation and Resource Dependence, this qualitative study employs in-depth, semi-structured interviews and thematic analysis. Findings reveal that funding choices significantly influence startups' capacity
Jorderosion är en global utmaning som påverkar miljontals hektar mark och leder till betydande förluster i jordbruksproduktivitet och ökad sedimentering i vattendrag och sjöar. Faktorer såsom intensivt jordbruk, avskogning och förändringar i markanvändning bidrar avsevärt till detta problem. I och med klimatförändringarnas intåg med ökade extrema väderförhållanden förväntas jorderosionen att öka jSoil erosion is a significant challenge in Rwanda, particularly within the Nyagako sub-catchment, where this study focuses on a delimited area. This research investigates the sources and contributing factors of soil erosion using GIS analysis, turbidity measurements, and sediment fingerprinting with a deconvoluted MixSIAR (D-MixSIAR) model in R. The objectives were to identify erosion-prone areas,
När vi tänker på skog som till exempel Amazonas har vi en förståelse av att de är jordens lungor. Just det uttrycket är något som man fått höra många gånger. Skog är växtlighet som omvandlar koldioxid till syre. Med denna bild av vad skog är kommer det för sig att anta att just skog skulle fungera som ett perfekt instrument för att samla in koldioxid vi släpper ut i atmosfären. För att vi ska kunnMitigation of climate change as the main goal of the Paris Agreement aims to keep the global mean temperature at 1.5 Celsius. As of now daily global temperature are surpassing this threshold which indicates the urgency to reenact more work in limiting green house gas emissions and at the same time optimize sequestration of carbon dioxide already in the atmosphere. One key instrument to sequester c
This master thesis analyzes the discourse of material in the newspaper LO-tidningen (later called Arbetet), with a particular focus on editorials. Trade unions have played an important historical role in Sweden. Drawing upon research that shows that the public discourse as a whole have become more influenced by neoliberal thought, this thesis focuses on whether the unions themselves have been affe
Alfa Laval är ett ledande industriföretag inom flera viktiga teknologier såsom: separation, pumpar, och värmeöverföring. Detta genom att tillverka produkter till t.ex. vattenrening, pastörisering, och produktion och överföring av energi, som i sin tur bidrar till ökat välstånd i världen. En av Alfa Lavals mest centrala produkttyper är värmeväxlare för värmeöverföring mellan vätskor och gaser. Ett Alfa Laval’s head office in Lund, Sweden, is the centre for research, development, and production of one of their key technologies: heat exchangers. The most common of these are the gasketed plate heat exchangers (GPHE). In these the liquid channels between heat transfer plates are sealed using rubber gaskets. The sealing ability of these gaskets are thus highly important for the performance of th

Celebrating its twentieth anniversary of accession into the European Union, Lithuania is a small state with ambitious goals related to further enlargement of the bloc. This thesis seeks to answer how this small EU member state aims to leverage EU’s enlargement policies in two ways: 1) by looking at what frames are used in their political communication; 2) by investigating how well 2 strategies, de
Experimental nuclear structure data coming from superheavy nuclei synthesis experiments often consists of correlated alpha decay chains. In the absence of neutron detectors - which would fully characterize the exit channel after the fusion-evaporation reaction - the sequence of decay energies and half-lives are the 'fingerprint' of the exit channel itself. Experimental data in this region
The hotel industry's growth raises concerns about its societal and environmental impacts, prompting hotels to engage in various practices for environmental preservation, fair HR management, and community well-being among others. Previously reporting on such practices in their sustainability reports, hotel chains now feel a stronger obligation to adhere to Environmental, Social, and Governance
