Since the building stock stands for significant part of the EU’s total energy use, energy renovations are needed in order to lower the negative environmental impacts. In Sweden, only 1 % of the total building stock is newly built i.e. the focus should be directed upon existing buildings. Moreover, most of the buildings in the “Million Program” from 1970´s are in need of renovations in order to kee
It is of importance for manufacturing companies to get an overview of costs associated with production. This thesis handles this subject with an emphasis on chosen cutting data as well as chosen tools since this has a large impact of the tooling cost. By modelling on cutting data available from tool manufacturers, cutting data can be implemented to test different cases in the production. This also
Reindeer husbandry has long been a central element of the traditional livelihood and culture of indigenous Sami people in northern Sweden. However, it faces several challenges from competing land uses, primarily forestry. Different forest conditions are desired by forestry and reindeer husbandry to accommodate each sectors’ distinct interests, promoting high timber and pulp production or improved
The simulation of diffusion bridges is a difficult statistical problem, and methods for this are attracting a great deal of attention. Analytically, the conditioning on a future pointintroducesasecondtermtothedriftoftheSDEthatincludesthetransitiondensity of the unconditioned process. However, transition densities of diffusion processes are often intractable, whereby other, often computationally int
The long coherence times of the 4f hyperfine levels of rare-earth-ions gives the possibility to use these as quantum computation devices. Moreover after being doped into a crystal the strong dipole-dipole interaction can be utilized to entangle them. Much work has been done here in Lund to attain as many of the DiVincenzo criteria as possible. At the moment work is being done in the creation of a
The energy sector in the world today is in the middle of a huge challenge regarding grid development and power production. Whilst a significant part of the world's population are struggling without access to electricity, the more developed part of the world is trying to replace existing energy sources into renewable ones, and are also facing the challenge of an aging grid which is in desperate
In the study presented in this paper, experimental data from a pneumatic hybrid has been compared to the results from a simulation of the engine in GT-Power. The engine in question is a single-cylinder Scania D12 diesel engine, which has been converted to work as a pneumatic hybrid. The base engine model, provided by Scania, is made in GT-Power and it is based on the same engine configuration as t
The focus of this thesis is on KEL and JK, two clinically important blood group systems, and the investigations of blood samples with aberrant antigen expression as in null and weak phenotypes, or with a phenotype that does not correspond to genotype. With the increasing use of DNA assays based on single nucleotide polymorphisms for blood group prediction, it is important to characterize the bloo
We theoretically investigate electronic transport through a junction where a quantum dot (QD) is tunnel coupled on both sides to semiconductor nanowires with strong spin-orbit interaction and proximity-induced superconductivity. The results are presented as stability diagrams, i.e., the differential conductance as a function of the bias voltage applied across the junction and the gate voltage used
A series of photosensitizers for NiO-based dye-sensitized solar cells is presented. Three model compounds containing a triphenylamine donor appended to a boron dipyrromethene (bodipy) chromophore have been successfully prepared and characterised using emission spectroscopy, electrochemistry and spectroelectrochemistry, to ultimately direct the design of dyes with more complex structures. Carboxyli
Today, there is considerable interest in integrated forest biorefineries which, besides pulp, produce high-value-added products, such as, polymers and carbon fibres. Lignin is the major non-cellulosic constituent of wood. It is a complex, amorphous highly crosslinked polyphenolic. Lignosulphonate in spent liquor in sulphite mills has long been isolated using ultra filtration. Generally, precipitat
The aim of this contribution is partly to build consensus on a consistent modelling methodology (CMM) of complex real processes in wastewater treatment by combining classical concepts with results from applied mathematics, and partly to apply it to the clarification-thickening process in the secondary settling tank. In the CMM, the real process should be approximated by a mathematical model (proce
Title: The Shadow Communication Model Seminar date: 2025-10-17 Course: Strategic Brand Management Authors: William Eriksson, Saga Nunstedt Strömberg, Ole Senkler Advisor: Mats Urde Keywords: Shadow message / Noise / Shannon Weaver / Semiotics / The Shadow Communication Model Research question: How do companies express shadow messaging in their advertisements, and in what ways does external n
Energy efficiency in buildings can be understood elaborately by evaluating its operational and embodied energy. Embodied energy is the sum of all the energy that is used to produce materials in a building construction. This study assesses various building parameters e.g. U-value of the materials, Window to Floor Area Ratio (WFR), location, etc. that affect the operational and embodied energy and u
Unsustainable use of natural resources has been the basis for economic growth since the industrial revolution. The linear model of extraction, processing, consumption and disposal has brought significant environmental consequences such as resource scarcity, pollution, biodiversity loss and climate change. The use of plastics is one example of unsustainable human behaviour. The use of them has offe
The aim of this paper was to establish sources for microplastic fibres and fragments based on the presence of specific colours (I) within different land use classes and (II) in relation to the location of wastewater treatment plants. Most of the colours did not result in significantly different counts between the land use classes, except for black fragments, which resulted in significantly higher
To understand how American cities “walk the talk” regarding climate change adaptation, the question “What effect do American city-wide adaptation efforts have on urban development trends?” is posed. The method covers the breadth and depth of the subject by studying the overall national climate discourse and utilizing three major American cities as case studies. Findings confirm adaptation efforts
Quantum teleportation is a way to transfer a quantum state between two locations, by utilizing a shared entangled state, measurements and the ability to communicate measurement outcomes between the two locations. This thesis consists of a theoretical investigation of an experiment that would implement quantum teleportation using single-electron states in mesoscopic architectures. First, we studied
