Visualisation of network loading and the impact of solar power at secondary substations in Lund.

Electrical power distribution is currently seeing both challenges and opportunities. On one hand, the digitisation of measurement data and modern measurement devices enable deeper analysis and planning of the grid. On the other hand, the expansion of privately owned photovoltaic systems and the customers' desire to produce their own electricity is an inevitable challenge that distribution comp

CUSTOMIZED QUANTIFICATION OF HOST CELL PROTEIN WITH BIO-LAYER INTERFEROMETRY

Visste du att många läkemedel tillverkas av genmodifierade bakterier? Också ofta i genmodifierade celler från däggdjur, till exempel från kinesiska hamstrars äggstockar. Läkemedel producerade i celler är de snabbast växande på marknaden, och kan till exempel användas för att producera insulin eller ett COVID-19 vaccin. I denna studie har en ny metod utvecklats för att säkerställa att sådana läkemeHost cell protein (HCP) is quantified in the purification steps of biopharmaceutical production and is part of ensuring the purity of the final drug product. The gold standard method for HCP quantification is enzyme-linked immunosorbent assay (ELISA), but a new approach is proposed here with fully customized bio-layer interferometry assays for yeast and chinese hamster ovary (CHO) cells. The new

Topology optimization with optimal spatially varying length scale

Density based topology optimization has become an efficient way to design optimal complex structures with different goals, constraints and boundary conditions. To regularize the solution, density filters are utilized and is controlled by the length scale. The length scale controls minimum feature sizes, as well as minimum curvatures in the structure. Usually a constant length scale is used through

Reaching for the Stars: An exploratory study to conceptualize product iconicity

Background/Problematization: Iconic brands are the gold standard of branding and have established a central role in the consumers’ lives. Behind every iconic brand, we can find iconic products. Despite the importance of these products, iconic products are overlooked in academia. Few studies have explored the concept and there is no common definition or comprehensive framework. This is restrictive

Stars Eating Planets

In a phase of instability during the dynamical evolution of some multiple exoplanetary systems, exchange of angular momentum and/or energy through gravitational interactions between planets will lead to alterations of their orbital properties. In some cases, planetary orbits end up crossing, which leads to close encounters between two planets. In turn, they undergo a planet--planet scattering even

Link performance measurement and improvement using Bluetooth mesh network

Bluetooth is a short-range technology, it helps with wireless communication between many electronic devices. Bluetooth low energy (BLE) is the advanced version of Bluetooth which uses low energy compared to the standard Bluetooth. Bluetooth mesh technology play a crucial role in the Internet of things (IoT). The IoT mesh technology enables many-to-many and one-to-many communication. This project d

Identification of high-amylose lines in a mutagenized oat population

Oat starch, like starch from other plants, is composed of amylose and amylopectin. The arrangement and abundance of these polysaccharides offers distinct properties to the formed starch. Starch with an elevated amount of amylose is of commercial interest and amount of amylose present in oats differs within cultivars. In this study, a mutant oat population developed by CropTailor was screened usin

Det dubbla främlingskapet - Invandrarens dilemma: att leva med eller mellan två kulturer

The study considers the phenomenon of double alienation, by which is meant the immigrant’s feeling of in a sense being alienated in their native country as well as in the new one. Those elements of their behaviour which are common in the one country or the other are expected there, whereas those which are not are seen as strange and different. This gives the immigrant a feeling of being at home in

LOKALISERA - alternativa framtider sprungna ur lokala förutsättningar

Vi lever idag i en värld vars system och strukturer tillåter oss människor att konsumera och producera långt över våra tillgångar. Om inga åtgärder görs riskerar vi oåterkalleliga förändringar i klimat och miljö som kommer att påverka förutsättningarna för kommande generationer. Klimatkrisen är global men vi måste agera lokalt. Nu. Hur vi utformar byggnader och samhällen har stor inverkan på milj

The Over-research & NGOisation Paradigm of the West Bank: Applied Cultural Analysis on the 'futility of research' and the 'burden of occupation'

The West Bank attracts countless researchers due to the conflict’s intractable label. On one hand, these researchers are drawn to the Palestinian-Israeli conflict due to logistical reasons: accessibility to the area, academic prestige, ample funding, grant and networking opportunities. On the other, researchers are allured due to an Orientalist fascination with conducting fieldwork in the West Ban

Reuse of white goods components - An interview study on drivers, barriers, and the future outlook

Utarmningen av resurser är ett växande problem som har påskyndat behovet att förändra våra konsumtionsmönster. Gamla, linjära modeller för produktion måste ersättas av nya tillvägagångssätt som minskar mängden avfall och maximerar värdet genom hela produktens livscykel. Denna strategi förkroppsligas av den Cirkulära Ekonomin (CE). En viktig del av CE är återbruk, det vill säga att gamla produkter The growing threat of resource depletion has spurred on the need to change how we consume. Old, linear modes of production must be replaced by an approach that reduces waste and maximizes value throughout the product’s entire life cycle. This strategy is embodied by the Circular Economy (CE). A key aspect of CE is reuse, referring to the repurposing of old products to avoid generating waste and de

The aim of this master thesis was to analyse the possibility to use fibre optic cables for critical safety features in high reliability facilities. In more detail, this report investigates how transferred data in fibre optic cables are affected by fire and if there is any risk that the data becomes corrupted or lost when exposed to fire conditions. This report also investigates if this risk can be

Trade effects of policy uncertainty: Evidence from the Brexit referendum

This paper examines the trade effects of increased trade policy uncertainty following the Brexit referendum by viewing the referendum’s influence on UK exports of goods to EU27 during the time period 2012-2019. This is done to give insight of how trade policy uncertainty can impact real economic behaviour, even when no classical trade barriers are changed. Methodologically, this is approached by e

Synchrotrons as a Source for Soft X-Ray Lithography

To move to lower modes in extreme ultra-violet lithography (EUVL) technology (and keep up with Moore’s law), new sources of soft X-ray radiation must be developed. It is clear from previous studies that Free Electron Lasers (FELs) can easily meet the in-band power requirements at these lower wavelength modes, however detailed studies for insertion devices (undulators) as a soft X-ray lithography (
