The aim of this bachelor degree project is to design a modular luminaire with a longer lifespan, in order to reduce consumption. The project aims to explore how design can contribute to sustainable development by creating a durable and adaptable lighting solution. The luminaire is versatile and can either be hung from the ceiling, mounted on the wall, or placed on a table. It can be expanded
The efficiency of combustion engines is crucial for their future development, prompting researchers to explore various factors to enhance performance. Among these factors, exhaust gases hold significant potential. Typically, exhaust gases carry about 30-40% of the engine's energy, which often remains underutilized. Although technologies like turbochargers have made progress in recovering some
Diskriminering, trakasserier och mobbning är några av de oftast förekommande problemen som en arbetsgivare kan mötas av när arbetsmiljön ska bearbetas. Sverige var en av de första länderna inom EU att anamma lagar och regler på ämnet. Trots den tidiga anpassningen är kunskap om arbetsgivarens makt och skyldigheter begränsade inom ämnet. Många fall av diskriminering eller trakasserier resulterar i
Syftet med undersökningen är att rapportera hur rytmikpedagogik och rörelsebaserad musikundervisning kan bidra till ömsesidig integration bland elever i en multikulturell svensk skola. Jag har genomfört en studie där jag kombinerar en internetbaserad enkät med en fokusgruppsintervju. Femtio musikpedagoger över hela Sverige svarade på enkäten, de flesta vilka arbetar med El Sistema. El Sistema erbjThe purpose of this study is to investigate how eurhythmics and body-based music education could contribute to mutual integration of students in a multicultural Swedish school. I have conducted a study, combining an Internet-based survey with a focus group interview. Fifty music teachers throughout Sweden answered the survey, most of who work at El Sistema. El Sistema offers optional music educati
Detta examensarbete undersöker styvhetsegenskaperna för tre armeringsmaterial: ferrocement, glasfiber- och kolfibertextilarmering, tillämpade för skalkonstruktioner. En av de strategier som användes för undersökningen var ett mekaniskt försök med kompositarmerade betongbalkar. Det mekaniska försöket skulle sedan verifieras med numeriska och analytiska modeller. Jämförelser mellan de mekaniska och The purpose of this master’s thesis is to investigate the stiffness properties of three reinforcement materials for concrete shell structures: ferrocement, glass-fibre textile and carbon-fibre textile. Three types of strategies were used to analyse the properties of the materials, an analytical model, experimental beam prototypes and a numerical analysis. Immediate comparison of the mechanical exp
Abstract I would like to thank my mentor Richard Murray at the Control and Dynamical Systems Department of California Institute of Technology (Caltech) for giving me the opportunity of conducting my master's thesis at Caltech and for his support during the project. I would also like to thank my other mentor Anders Rantzer at the Department of Automatic Control of Lund Institute of Technology u
This thesis describes bio-ethanol production and use for transport fuel in Ethiopia, focusing on current status and potential, barriers, implications and recommendations for a sustainable market. The need for such research is justified as it paves the way for bio-ethanol development in Ethiopia towards a more sustainable path as challenges are surmounted. Bio-ethanol from molasses is identified in
NIMCO Controls AB is a company located in Malmö, Sweden, that manufactures hydraulic valves mainly for the farming industry. They proposed me to work on three independent design projects to renew their product range. The first topic was a platform research for handgrips. As the company uses lots of different lever systems that need a handle, the main objective was to design a platform which deriva
Bangladesh is known to be the country worst hit by environmental changes at the same time as it is a densely populated country in South Asia. Questions of climate change have been debated during the last decades and the voices of the affected have now also been heard. Bangladesh will lose land as the sea level rises and floods occur more often. People have to escape these challenges and move to a
Computer simulation and modelling was used to simulate a real time environment in preparative chromatography to evaluate the performance of three different strategies for pooling control for different levels of robustness. The pooling problem was based around a separation case where three different insulin species were to be separated while disturbances to the modulators potassium chloride, ethano
This report details the development and evaluation of fibre-based primary packaging concepts for the growing ready-meals category, focusing on a concept packaging design project for Micvac AB. The research methodology employed the Double Diamond of Design Thinking as an innovation model. The project encompassed an assessment of the desirability, feasibility, and viability of fiber-based packaging.
With the rapid growth of AI and large language models, concerns about their energy consumption have become increasingly prominent. The traditional digital von Neumann architecture is ill-suited for deep neural networks, prompting the exploration of neuromorphic computational models. These models draw inspiration from nature and the brain to integrate memory and computation efficiently. This thesis
Every day more devices all over the world are connected to networks. Some of these devices have microphones that could potentially be used in a networked array. This opens up the possibility to determine where sounds in the environment are produced, given the positions of the microphones are known. This thesis investigates the feasibility of using a number of network connected speakers with built-
This thesis examines what barriers and opportunities exist for public participation in addressing biodiversity loss and adapting to climate change in Swedish biosphere reserves (BRs). This was approached by conducting an instrumental case study of all seven BRs in Sweden, consisting of semi-structured interviews and a case-specific literature review. The results identified that while a significant
Lignin, the most abundant aromatic polymer in nature, is a valuable renewable resource due to its high phenolic compound content. Utilizing depolymerized lignin for the bioproduction of valuable industrial precursors such as muconic acid has garnered significant attention. In this study, several genetically modified strains of Pseudomonas putida were constructed to bioconvert vanillin and guaiacol
Lake–atmosphere carbon exchanges can be significantly affected by photochemical dissolved organic matter (DOM) mineralization. However, our understanding of how increasing allochthonous organic carbon input affects the photoreactivity of DOM per unit of absorbed incoming light is incomplete. Here, we measured the absorption of ultraviolet (UV) light and subsequent photochemical DOM decay in 148 la
The study of rapid and stochastic events that involve multiple species, such as chemical reactions and plasma dynamics, requires means to capture multispectral information in two dimensions at both high temporal- and spatial resolution. Commercially available cameras that provide high temporal resolution are based on either signal intensification or rapid data acquisition. Intensified cameras prov
