Field trials in three European countries, the Netherlands, Spain and Sweden were carried out in order to investigate the effects of an in-car speed limiter. The trials were carried out on urban and rural roads including motorways. A so-called unobtrusive instrumented car was used, where all the measuring equipment was hidden. All the speed limit categories in the respective countries, ranging from
The most common form of technology for energy utilization via anaerobic treatment is slurry digestion with a low solids contents, such as sewage sludge or manure. Process control and maintenance are relatively simple, but costs involved with liquid handling and heating favour large, centralised plants. Raising the solids content of a digester to 30% significantly improves the economy of anaerobic
Path dependence has claimed its place as a core component of economic geography, but recently the concept has been criticized for the sole focus on external shocks and lock-ins. This critique has inspired scholarly work on new path development which gives great attention to endogenous pre-conditions for new path development. However, several shortcomings still exist. The main aim of this chapter i
Background: The molecular out of Africa hypothesis, OOAH, has been considered as an established fact amid population geneticists for some 25–30 years despite the early concern with it among phylogeneticists with experience beyond that of Homo. The palaeontological support for the hypothesis is also questionable, a circumstance that in the light of expanding Eurasian palaeontological knowledge has
The European Colonoscopy Quality Investigation (ECQI) Group aims to raise awareness for improvement in colonoscopy standards across Europe. We analyzed data collected on a sample of procedures conducted across Europe to evaluate the achievement of the European Society of Gastrointestinal Endoscopy (ESGE) mean withdrawal time (WT) target. We also investigated factors associated with WT, in the hope
The 2015 Migration Crisis forced the European Union to rethink its security. In order to deal with incoming pressure and security concern, several institutional changes were undertaked in the aftermath of the crisis. Frontex received the extended mandate and now conducts operations in third countries independently. Common Security and Defence Policy received tasks in relation to migration and bord
Oleaginous microorganisms provide an opportunity to produce oils without the use of arable land for cultivation of oil-containing plants. Oleaginous microorganisms are also capable of storing products of pharmaceutical interest alongside storing polymers, which could open new opportunities in the bioplastic industry. Oily yeasts have several advantages in comparison to alternatives; their doubling
Förlust av biodiversitet är ett av de största globala miljöbetingade problemen idag. Arter står inför ökande och potentiellt synergistiska hot från markomvandling och överexploatering av naturresurser, från globala såväl som lokala socioekonomiska krafter. Populationerna av ryggradsdjur har mellan år 1970 och 2016 visat på en global genomsnittlig minskning på 68 procent. Större djur, s.k. megafaun
In this thesis work, a highly linear passive attenuator and mixer were designed to be used in a wide-band Transmission Observation Receiver (TOR). The TOR is a low IF receiver that accepts RF frequencies from 2GHz to 7GHz, and produces corresponding IF bandwidths of 280MHz to 990MHz respectively, using low side LO injection. The dynamic range is maximized by using passive topologies for both the a
Även om matchfixning och uppgjorda matcher har blivit ett allt mer omdiskuterat ämne det senaste åren saknas det i stort sett kunskap om hur läget är i Sverige. Det finns några enstaka forskningsrapporter och två hovrättsavgörande. Avsikten med uppsatsen har varit att undersöka vilka legala möjligheter det finns idag för att beivra matchfixning och hur den föreslagna spelfuskbestämmelsen i SOU 20Even if match fixing and manipulated matches have been a widely discussed topic the last few years, we still lack any deeper knowledge about the situation in Sweden apart from a few research reports and two rulings from the Court of Appeal. My intention with this bachelor thesis have been to examine which possibilities we have today to prosecute match fixing and how the proposed offence of cheati
Applications based on Wireless Sensor Networks are making their way into all kinds of industries. Today, they can do anything from off-loading hospitals by monitoring patients in their homes to regulating production lines in factories. More often than not, they perform some kind of surveillance and tracking. Thus, in most cases the information they carry is sensitive, rendering good encryption sch
Eventuella beteendemässiga konsekvenser av pornografianvändande har undersökts flitigt under de senaste decennierna. Forskningen har dock inte inkorporerat kontextuella aspekter av pornografianvändande eller intresserat sig för möjliga samband med användarnas egen sexualitet. Denna studies första syfte var att undersöka pornografianvändande i en icke-klinisk population av 16- till 30-åringar i Sve

“Freedom of alliances in peace aiming for neutrality in war”. Those are the classic words of the Swedish security policy. But are they still relevant? Has a change taken place? And what does it depend on? This essay examines whether the Swedish security doctrine has changed over time and whether the security doctrine depends on a realist and constructivist perspective in IR-theory. It is a compara
Kvantdatorer har fått mycket fokus i media de senaste åren på grund av sin potentiella förmåga att lösa problem som är för tidskrävande för att låta sig lösas på klassiska datorer. Kvantdatorer skiljer sig i grunden från dagens datorer, genom att bygga på gåtfulla kvantmekaniska egenskaper. En sådan är kvantsuperposition, som innebär att en partikel kan vara i flera kvanttillstånd samtidigt. AntagQuantum annealing provides a promising avenue for obtaining good approximate solutions to difficult optimization problems. Protein folding represents one such problem. For testing novel algorithms and technologies, simplified lattice models are well suited, as they represent considerable computational challenges despite their simplicity. One such model is the HP model, where the protein is represe
Objective Second language learning continues to be a field of growing interest both in academia and everyday life. As such, a more comprehensive understanding of the best learning methods remains an important area of focus. This study aimed to investigate single-session vocabulary acquisition and neural underpinnings of language learning through Diffusion Tensor Imaging (DTI), in relation to immer
Efforts to reduce energy consumption in buildings have increased with the pending impact of climate change. Heat losses through airing behaviours remain a largely unknown factor due to the variety of reasons for opening a window, making generalization difficult. Currently, an estimation of 4 kWh/m2 heated area for airing heat loss is assumed in Sweden. Additionally, the resulting airflow from open
Fund companies and banks argue that letting them manage one’s money is a wise decision. They argue that they are able to create substantial growth in value for the investor without requiring any other input than a small fee and an amount to be invested. This essay tests this claim in a two folded analysis. Time series data with historical value developments of 24 out of the 30 largest Swedish equ
