The thesis aims to develop knowledge of the physics and thermodynamics behind a nonlinearity in an air cooling system for an plastic extruder machine. To accomplish this, both nonlinear and linearized models were set up in Matlab and Simulink environments based on the laws of physics and thermodynamics. Simulations were run to achieve and analyze step responses, and different PI control structures
This thesis attempts to implement a library in pure Python for building real-time Brain-Computer Interface (BCI) systems. The library does this by employing nodes containing data transformation methods—filtering, classification, data acquisition, and more. These nodes are linked together to create pipelines of nodes in which data flows. Due to the asynchronous nature of the data flow the library w

With the projection of a growing amount of waste from photovoltaic (PV) panels in coming years, experts and researchers have highlighted the importance of the circular economy approach to face this challenge. With this approach, risks linked to the composition of PV panels, such as pollution and wastage of valuable materials, can be reduced. Therefore, this thesis aims to provide a systematic view
Syfte: Syftet med uppsatsen är att undersöka hur chefer upplever generation Z och vilka drag de tillskriver de anställda utifrån generationstillhörighet. Vidare att förstå hur ledarna anser att de bör anpassa sitt ledarskap till följd av de tillskrivna dragen och på så sätt bidra till teorin om implicita följarskapsteorier. Metod: För att uppnå studiens syfte och besvara frågeställningen har en sPurpose: The aim of this study is to analyze how managers perceive generation Z and what attributes they ascribe to the employees based on generational belonging. Furthermore, what adaptations of their leadership they claim to make as consequence to the ascribed characteristics. In this way, we also make a contribution to implicit followership theories. Methodology: In order to achieve the purpos
På senare tid har det påträffats olika typer av skador på fibercementskivor monterade i fasader som har varit svåra att härleda till en specifik orsak. Den främsta skadan som uppkommit är sprickbildning men det har även påträffats andra defekter så som utbuktande skivor. Dessa skador har i flera fall härletts till handhavandefel vid montage men fukt-och temperaturbetingade rörelser tros även vara Recently, various types of damages have been found on fibre cement boards mounted in facades which have been difficult to trace to a specific cause. The main damage that has occurred is cracking but other defects have also been found, such as bulging boards. These damages have in several cases been attributed to handling errors during assembly, but moisture and temperature-related movements are al
Simulating vehicle scenarios for autonomous cars saves both time and money compared to physical testing. For this to work efficiently a sophisticated simulation software is often needed. Esmini is an open-source, lightweight vehicle simulator that can handle advanced traffic scenarios. When designing scenarios to be used for testing autonomous vehicles, it is often beneficial to set up relative ve
In surveillance contexts, radars can be used to monitor an area, detecting and tracking moving objects inside it. Monitored areas in urban environments often contain many surfaces that reflect radar waves, which can have the undesired consequence of a single object producing multiple tracks due to multipath propagation effects. This thesis considers a method of identifying if a track is produced b
This essay analyses conceptual metaphors in the Beatles’ song lyrics and observes how Lennon and McCartney’s use of metaphorical concepts evolved in the 1960’s. The study has an empirical and qualitative approach with quantitative elements, and employs the framework of Conceptual Metaphor Theory (CMT). Three specific RQs are studied in this thesis: (a) how the metaphors in Lennon and McCartney’s l
Our closest living relatives are the chimpanzees, with whom we last shared a common ancestor about 5-6 million years ago. 98% of our protein-coding regions are identical. However, despite our close similarities when it comes to the protein-coding regions in our genome, our cognitive abilities and the size of our brains differ considerably. The Non coding regions, which cover 98% of our genome, are
Minispares, or spare wheels, can often cause a lot of problems for the control of the car since it rotates notably faster than normal tyres. This because it is often smaller to reduce weight. When a minispare is used, it needs to be detected for the control system to understand that one tyre is allowed to spin faster compared to the others. If the control system does not know this, it will believe
Bakgrund: Lek är en grundläggande aktivitet och en mänsklig rättighet. Genom att delta i lek tillägnar sig barn nya erfarenheter vilket leder till utveckling. Lekplatsers unika miljö möjliggör barns utveckling men för barn med funktionsnedsättning kan denna miljö innebära utmaningar av fysisk, social eller kognitiv karaktär. Syfte: Studiens syfte var att kartlägga hur miljön på offentliga lekplatBackground: Play is an essential activity and a human right. Through participation in play children can get experience which leads to development. The playground is an important place for children but for children with disabilities the occupations on playgrounds can often mean physical, social or cognitive challenges. Aim: The aim of this study was to explore how environmental factors in public pl
Maskar och ärrvävnad - Hur påverkar det färgen hos fisk? För att överleva olika typer av infektioner är det viktigt att immunförsvaret fungerar. Det kan dock också vara kostsamt att ha ett immunförsvar. Ett exempel är feber. Kroppen slår tillbaka mot en infektion, men själv känner en sig inte direkt manad till mycket annat än att sova. Kroppen måste avväga vad som är viktigt att lägga energi på vTo understand why immune traits affect the fitness of its host is an important part of understanding why and how immune responses evolve. In threespine stickleback (Gasterosteus aculeatus), fibrosis is an immune response evolved to combat infection of the tapeworm parasite Schistocephalus solidus. Already known is that fibrosis leads to a reduced mating success for males. Here I investigated wheth
Playing games with reinforcement learning has for years been a target for research and has seen incredible breakthroughs in recent years. Reinforcement learning is a type of machine learning, which can be combined with the concept of deep learning, resulting in what is called deep reinforcement learning. The promise of deep reinforcement learning attracts businesses that aim to get an edge over tr
Den globala uppvärmningen har stora effekter på det subarktiska ekosystemet i norra Sverige. De ökande temperaturerna i dessa ekosystem har lett till ett tinande av permafrosten i marken. Permafrosten innehåller stora mängder kol och när tjälen i marken försvinner blir detta kol tillgängligt för nedbrytning av mikrober i marken. Denna nedbrytning av kol i kombination med en våtare mark leder till The northern permafrost regions are experiencing a rapid warming as surface temperatures are rising, causing a disintegration of permafrost and a deepening of the active layer (AL). This releases previously frozen carbon, making it available for decomposition by microbes. The combination of the high microbial activity and overall wetter soils may cause anoxic conditions and in turn methane (CH4) a
The Covid-19 pandemic is in multiple ways a new type of crisis. The virus outbreak has had a serious impact on global health and has caused an economic downturn that is heavily driven by the restrictions implemented to attenuate the health-crisis. Apart from affecting the mobility of individuals, these restrictions impose additional constraints that policy makers need to adhere to when conducting
Human capital has been acknowledged as directly related to a firm’s performance. However, few researchers have analysed the influence of human capital and its degree of transferability into new venture development. This thesis aims to explore the phenomenon of individuals leaving careers in Small and Medium-sized Enterprises (SME) to establish new ventures. Specifically, this thesis aims to provid
The humanitarian crises, which suddenly emerged in Akhalgori and claimed the lives of dozens of people, raised questions on the legal responsibility of Georgia and Russia to guarantee timely and adequate healthcare in the district. The uncertainties regarding the state’s obligations were caused by the specific legal status of Akhalgori, which is Georgia’s lost territory beyond its effective contro
Ämnesplanen i svenska i gymnasiet ska bygga på men inte överlappa kursplanen i svenska i grundskolan. Grammatiken beskrivs endast implicit i Svenska 1 och omnämns explicit först i Svenska 2. Detta innebär att grammatikundervisning och metaspråk i svenskämnet på gymnasiet i hög grad är beroende av elevernas grammatiska förkunskaper från grundskolan. Syftet var att undersöka hur svensklärare hanteraThe syllabus in Swedish in upper secondary school should be based on, but not overlap, the syllabus in Swedish in primary school. Grammar is only implicitly described in Swedish 1 and is explicitly mentioned only once you move on to Swedish 2. This means that grammar teaching and metalanguage in Swedish in upper secondary school is to a large extent dependent on the students' prior grammatical
Since the outbreak of the COVID-19 pandemic, vaccination hesitancy has not become a new phenomenon, but a new threat. Although a large body of research literature exists that focuses on the influence of frames on intention to vaccinate, no framing studies exist yet that address the COVID-19 vaccine due to the recent pandemic. This study aims to produce new knowledge on the influence of gain and lo
