Grafdatabaser blir allt vanligare, samtidigt som antalet processorer i moderna datorer ökar mer och mer. Vi tittar i detta arbete på hur parallelliserad sökning kan leda till prestandavinster i den populära grafdatabashanteraren Neo4j. För att ta reda på om det går att parallellisera en enskild sökning i en grafdatabas och hur stor påverkan detta då har på svarstider, skapade vi vår egen modifieIn this report we investigate parallel execution of queries in graph databases. We analyse different methods of parallelization, how to introduce query parallelization to a graph database, which query operations that are suitable for parallelization and if we can improve the execution time of a single query. We do this by designing and implementing a parallel runtime for the Cypher query language

The research problem of this thesis stems from the current legal practices on the humanitarian exception in relation to human smuggling. These practices have been identified as problematic, as family relationships have become the basis for applying the exception. Arguably, this undermines the principle idea of the exception, inasmuch as humanitarian assistance should not be based on kinship. Build

Modern embedded development flows often depend on FPGA board usage for pre-ASIC system verification. The purpose of this project is to instead explore the usage of Electronic System Level (ESL) hardware-software co-simulation through the usage of ARM SoC Designer tool to create a virtual prototype of a cellular IoT modem and thereafter compare the benefits of including such a methodology into the

This thesis will investigate how Erik Hobsbawm’s theory of ‘social banditry’ can be applied to a contemporary setting to explain the strength and workings of ethnic Albanian organised crime groups. The paper will delve into a pre-existing debate surrounding the effectiveness of this theoretical lens as a method to account for the global phenomenon of banditry (particularly in the feudalist age).

Arbetet behandlar värdegrundsarbete på en gymnasieskola i Lund ur ett elevperspektiv men förklarat med stöd av Pierre Bourdieus begrepp. Syftet är att med utgångspunkt från Bourdieus begrepp om kapital, habitus och fält nå fördjupad förståelse av elevernas uppfattning om det värdegrundsarbete som bedrivs vid den gymnasieskola de alla är elever på. Genom kvalitativa intervjuer av såväl enskilda ele

Fossila bränslen är mycket viktiga för dagens samhälle och transportsektorn är nästan helt beroende av dem. Tyvärr påverkar de miljön negativt och bidrar till att växthusgasnivå ökar. Jordens medeltemperatur har ökat med 0.8°C sedan början av industrialiseringen. Den globala uppvärmningen är ett naturligt förlopp, men har under de senaste åren varit en stor del av människors bidrag. Idag har atmosOil is very important for today’s society and the transportation sector is almost completely dependent on this material. Unfortunately, it affects the level of greenhouse gases negatively which in turn contribute to global warming. Therefore, it is necessary to reduce greenhouse gas emissions, especially in the sectors that emit the most, as transportation sector. The European Parliament has decid

Current consumption and production cannot rely any longer on traditional linear approach to satisfy increasing needs of the growing population. Instead, the principles of circularity should be applied. One way to do is to adopt industrial symbiosis approach, which entails physical exchange of materials, energy, water and/or by-products between traditionally separate industries. However, the uptake

Cleantech—technologies with a reduced environmental impact—has emerged as an important set of solutions for addressing pollution and its impacts in China. The goal of this study is to map out wherein Chinese actors with first-hand knowledge of cleantech investments think the largest domestic investment opportunities are found, understand the underlying reasons, and then evaluate how consistently t

Fat-filled milk powders are manufactured by blending skim milk powder with vegetable oil and these powders have gained a great economic importance. Sensible selection of vegetable oil can help in satisfying both nutritional features and functional characteristics of fat for dairy application. The stability of milk powders can be affected by its composition, mainly the composition of fats which can

This is a Bachelor thesis on the subject of the food industry’s influence over the EU institutions. The purpose of the thesis is to find out how the great food companies affect the EU legislation on sugar regulation through lobbying. The thesis describes how the EU food- and health policies are shaped and how the lobbying works. The methodology used for the thesis is a qualitative content analysis

Jordbävningar i Sverige är ovanliga, så pass att dimensionering för seismisk last inte sker i Sverige med undantag för speciella byggnader såsom kärnkraftverk. Jordbävningsdimensionering regleras av Eurokod 8 och Boverket har i den svenska bilagan beslutat att inte utge föreskrifter eller allmänna råd avseende användningen av koden eftersom den torde komma till användning i Sverige enbart i mycketIn 2013 the European Seismic Hazard Model 2013 (ESHM13) was released as a result of the EU-funded project Seismic Harmonization in Europe (SHARE). This hazard model provides seismic data applicable for structural engineering for every location in Europe and Turkey that directly correlates to the seismic regulations provided by Eurocode 8. Currently, earthquake engineering according to Eurocode is

In public safety oversight authorities are traditionally assumed responsible of safeguarding operation and promoting safety by defining prescriptions and observing that they are complied with. Regulated entities on their side are assumed responsibility for complying. While this compliance-based approach has contributed to current levels of safety, it is increasingly debated that it has limitatio

Statligt stöd är ett område för konkurrenslagstiftning. Statsstödsåtgärder används för att avhjälpa marknadsmisslyckanden och hjälpa företag när de står inför svårigheter. Statsstödskontroll syftar till att skapa lika villkor för stödda och icke-stödda företag. Under finanskrisen 2007–2009 har flera banker stött på svårigheter, och medlemsstaterna har tvingats hjälpa dem på olika sätt. Europeiska State aid is an area of competition law. State aid measures are used to remedy market failures and to help undertakings when they are facing difficulties. State aid control aims at ensuring a level playing field between aided and non-aided firms. During the 2007-2009 financial crisis, several banks have encountered difficulties, and Member States have been forced to help them out through diverse m

Att skjuta lasrar ut i luften och på insekter: varför? En laser är en väldigt stark, enfärgad ljusstråle. De allra häftigaste lasrarna hittar man så klart bara i Star Wars, men faktum är att man kan hitta lasrar precis överallt. När polisen mäter hur fort bilar kör så sker det med en laser. När backvarnaren på bilen börjar pipa har det skett en lasermätning som avgör avståndet till ett hinder. OvThis thesis focusses on the implementation of two elastic lidar (light detection and ranging) techniques for the monitoring of atmospheric aerosols and insects at short-wave infrared wavelengths. Data acquisition software was developed for a time-of-flight system, housed in the Lund University Mobile Biosphere Observatory (LUMBO), with consideration to the intended entomological application. Onc

Denna studie syftar till att förstå hur studerande kvinnor mellan 20 och 30 år, bosatta i Malmö, upplever det individualiserade miljöansvaret vid inköp av mat i sin vardag. Bakgrunden till studien är att det de senaste åren har skett en ansvarsförskjutning från stat till individ gällande miljöproblem och -lösningar. Med anledning av detta ligger det mer vikt vid att individen, och särskilt konsume

The dopamine transporter (DAT) is responsible for dopamine (DA) clearance in the synaptic cleft, and thus crucial for maintaining DA homeostasis in the central nervous system (CNS). Mutations in the DAT coding gene have been associated with both movement and psychiatric disorders, such as parkinsonism and attention-deficit hyperactivity disorder (ADHD). However, the detailed contribution of DAT in

Wind turbines are most commonly located in remote areas to harness strong and constant winds, however, with the current growing rate of urbanisation, producing clean energy within the city closer to consumers is becoming crucial. Research has shown that the urban morphology has a strong capacity to influence air flow and ‘street canyons’ have the potential to channel the wind towards turbines in t

Blockchain technology is increasingly expected to revolutionise businesses and promises to create trustworthy transparency. This study aimed to investigate the potentials of blockchain technology for supply chain transparency beyond the growing glorification. Methodology: The potentials, as well as immaturities and

Test av ny metod för att hitta mörk materia partikeln Under mänsklighetens historia har vår förståelse av vad som är universums fundamentala byggstenar förändrats. Vi vet att nuvarande teori, standardmodellen, är inkomplett eftersom att den inte inkluderar gravitation, mörk materia med flera. Mörk materia kan inkluderas om dess partikel observeras. För att observera en ny partikel så subtraherar The aim of this thesis is to develop, test and evaluate a penalized basis spline as a method for representing the Standard Model background in dijet searches from proton-proton collisions at the Large Hadron Collider. Current representations of the Standard Model background are complex and dependent on current assumptions of the Standard Model. Using a P-spline is interesting because of its simpli
