Firstly four different SLAM algorithms are implemented and then four different pathing al

China’s perception of the EU: Is the EU a friend, an enemy, or a “frenemy”? A case study of China Daily’s framing of the EU

The purpose of this study was to study China’s perception of the EU by analyzing China Daily’s framing of the Union, which is a Chinese government-owned newspaper. In particular, the EU-China relationship holds great significance in international affairs. However, in recent years, the bilateral ties have experienced various setbacks due to conceptual differences between the actors. Thus, I argue t

Use of crushed mussel shells for the remediation of heavy metal contaminated soils

Can mussel shells cure heavy metal polluted soils? Heavy metal contamination in soils has become a global concern, as it has recently been increasing due to anthropogenic factors, such as agricultural and mining activities. These practices have led to elevated and unsustainable metal concentrations in soils, causing toxicity and fatality to plants and other living organisms. Heavy metal polluted

Seasonal variation of LAI in Swedish coniferous forest

Leaf Area Index (LAI) is quantity representing the amount of foliage in the canopy, which makes it an important parameter for analysing terrestrial ecosystems. Traditional methods of measuring LAI were done by analysing hemispherical photographs by hand and were very time consuming, requiring specific weather conditions (Jonckheere et al. 2004). Modern methods, including remote sensing, have much

Investigation of flux dependence on viscosity in ultrafiltration

Jordbruksgrödor används huvudsakligen som livsmedel, men som en konsekvens av en strävan efter ett mer fossilfritt samhälle sker ett ständigt sökande efter andra användningsområden, i synnerhet för biprodukter inom livsmedelssektorn. En sådan biprodukt från sockerindustrin är melass. Melass består mestadels av socker men också av bl.a. andra organiska föreningar och salter, och har traditionellt aThis project aims to compare the effect of viscosity on flux for high viscosity liquids. The performance of two different viscous solutions was studied in a plate-and-frame membrane module. The solutions used were based on molasses, which is a liquid containing mainly low-molar mass components and konjac glucomannan (KGM) which is a substance with high molar mass. The change of the mass transport

A General Purpose Near Data Processing Architecture Optimized for Data-intensive Applications

In recent years, as Internet of Things (IoT) and machine learning technologies have advanced, there has been increasing interest in the study of energy-efficient and flexible architectures for embedded systems. To bridge the performance gap between microprocessors and memory systems, Near-Data Processing (NDP) was introduced. Although some works have implemented NDP, few of them utilize the microp

Synthesis and characterization of mononuclear Fe(II) complexes based on two new pentadentate N5-donor ligands

Levande organismer är mycket avancerade biokemiska system, där ett otal kemiska reaktioner sker hela tiden. I dessa reaktioner omvandlas molekyler (substrat), till en annan molekyl (produkt) under milda betingelser; med detta menas till exempel neutralt pH, atmosfärstryck och kroppstemperatur. Detta är möjligt på grund av biologiska katalysatorer, kallade enzymer, då dessa reaktioner utförs i det Metalloenzymes have the ability to enhance oxidation reactions within biological systems, which have spurred efforts to synthesize biomimetic FeII complexes. That being said, two N4Py-derivative ligands N-((6-(4-chlorophenyl)pyridine-2-yl)methyl)-1,1-di(pyridine-2-yl)-N-(pyridine-2-ylmethyl)methanamine (L1) and N,N-bis((6-(4-chlorophenyl)pyridin-2-yl)methyl)-1,1-di(pyridin-2-yl)methanamine (L2) we
