Molecular imprinting technology is a field where polymer technology is utilised to synthesise high affinity particles, much like antibodies. This project has dealt with the imprinting of the neurotransmitter molecules serotonin and histamine. Serotonin polymers were synthesised using methacrylic acid and acrylamide as functional monomers relying on hydrogen bonding for the imprinting effect. None

Syftet med mitt master projekt i industriell design vid IKDC var att utveckla och uppgradera produkten trygghetslarm. Detta larm skall kunna göra det möjligt för äldre och rörelsehindrade att bo kvar i hemmiljön, med tryggad kontakt till hemtjänsten när olyckan är framme. Bakgrunden till valet av projekt är bland annat personliga skäl, då trygghetslarm varit livsavgörande för några av mina släktin

The road haulage industry is a fundamental part of today’s society. The companies of haulage stand before a challenge, as the environmental and economic sustainability demands are increasing. The automotive industry tries to meet these demands by developing intelligent systems that will decrease the fuel consumption. The two systems, predictive controller and platooning, are two intelligent solut

Det finns ett växande behov av miljövänliga sätt att transportera sig och därför har elcykeln slagit stort i Sverige. Elcykeln används ofta som transportmedel till och från jobbet men har potential att användas i andra sammanhang också. Miljöpåverkan orsakad av transport under semesterresor har uppmärksammats på senare tid. Samtidigt ökar efterfrågan på soft adventures, bekväma och tillrättalagda There is a growing demand for environmentally friendly ways of transportation, and therefore the electric bicycle has been booming in Sweden. The electric bicycle is often used as means of transportation to and from work, but has potential to be used in other situations as well. The environmental impact caused by transportation during holidays has recently gained attention. At the same time the de

Due to its high vulnerability, permafrost is one of the key features studied in the field of climate change impacts. Permafrost is widespread in the Arctic region. The majority of the area underlain by permafrost is however difficult to access for in-situ monitoring and it is difficult to get an overview of the current state of permafrost in many areas. Permafrost modeling provides a solution whi

This thesis covers established procedures for the successful and attempted immobilization of lipases and phospholipases to various hydrophobic support materials, utilizing a rotating bed reactor, magnetic stirrer and tube-rotator. The design of a robust platform was established with great instrumental knowledge and proper conditioning for the creation of efficient immobilizations and activity assa

Highly glazed spaces are continuously increasing in popularity due to architectural attractiveness. However, increased use of glass often jeopardizes thermal comfort in several ways and problem of overheating is one of them. A way to face this problem is to appropriately use solar control mechanisms. However, a proper selection of solar control mechanisms from an early design stage is a complex ta

The main objective of this thesis is to present the article "An estimate of the condition number of a matrix", written by Cline et.al., which describes an algorithm for obtaining a reliable order of magnitude estimate of the condition number of a matrix in O(n^2) operations. In addition, the thesis introduces an iterative process for estimating the condition number in the 2-norm with arb

Evacuation models can be reliably used if they are sufficiently validated for the application in question (e.g. Fire Safety Engineering). To be useful, an evacuation model should therefore be an accurate enough representation of the real-world behaviour of evacuees. The scope of this work was to determine how accurately the model crowd:it (making use of the Optimal Steps Model) provides a represen

This master's thesis explores the potential of integrating floating wind power into Power-to-X (P2X) megaprojects, with a focus on maximizing the output of chemical energy carriers through optimal energy mix strategies. The study evaluates the economic viability and technological efficiency of combining floating wind turbines with photovoltaic panels and battery energy storage systems (BESS) i

Ultrasound optical tomography is a medical imaging modality that combines ultrasound and light to improve the low resolution of optical imaging caused by scattering in tissue. Photons passing through an ultrasound pulse have a probability of being frequency shifted. By filtering out these photons and analysing them, images with optical contrast and ultrasound resolution can be obtained. In this t

This thesis considers solitary standing wave solutions to the Davey-Stewart-son equation, which is a model for surface waves on a body of water in three dimensions. In a special case, the Davey-Stewartson equation is reduced to the well-known non-linear Schrödinger equation with cubic power which is known to have a countable familiy of radial standing waves. One of the aims of this thesis is to in

Purpose – The purpose of this study is to uncover what motivational factors exists for companies to use co-creational methods. It also aims to recognize what beneficial factors can come from using these methods. The restriction of using social media depending on industry or size of company will be reflected upon. The main research question is “What motivates companies to use customer co-creation a

There are high hopes in Greenland that the country will go from being a nation of fishermen to a nation of oil producers. But what do we really know about the prospects? Our thesis investigates how favourable the geological, economic and institutional conditions are for building a self-­sustaining economy in Greenland based on its hydrocarbon resources. The geological conclusions are encouraging.

Datering med accelerator? Måhända låter det otympligt, men när det handlar om att datera med hjälp av sällsynta slag av grundämnen kan varje atom räknas. Då handlar det om att kunna räkna enskilda atomer, vilket är möjligt med acceleratorbaserad masspektrometri, AMS. Lunds Universitet har en accelerator anpassad just för den här sortens mätningar, vilken främst nyttjas av institutionerna för fysiFor decades, accelerator mass spectrometry (AMS) has been used for radiocarbon dating. The background of this technique is outlined along with an in-depth look at the graphitization process used to prepare samples for AMS analysis. The technology necessary to achieve the vacuum quality needed in graphitization and accelerator mass spectrometry is discussed as well. The graphitization system belong

Reklam kan inte ses som en isolerad kommunikation mellan företag och konsumenter, den existerar i samtiden, i en kontext och i ett samhälle som låter sig påverkas av den. Vad som exponeras i det offentliga påverkar de uppfattningar och föreställning människor har om omvärlden i ett långsiktigt perspektiv. Syftet med studien är att undersöka och skapa förståelse för hur reklambyråer hanterar balans

Reuse of different types of experience is a key issue in successful improvement in software engineering. The approach taken in the Quality Improvement Paradigm (QIP) and its supporting organisation, tile Experience Factory (EF), is to define an Experience Base (EB), where all types of reusable objects are organised and stored. The objects may be of any type related to software development, for exa
