The combined contribution to highway safety of pavement surface and geometric design indicators is not well investigated due to the complexity of data collection and high time variability of pavement surface conditions. Introduction of high efficiency equipment for comprehensive road surveys is mitigating this issue, expanding possibilities of data integration. In this framework, the present study

We establish support and resistance levels from data in intraday currency exchange market activity based on machine learning methods. Specifically we design two semi-supervised classification neural networks. The first one is based on a variant of the K-means method while the second is based on a Gaussian mixture model with expectation maximisation. Each performs classification from tick data on v

Supplemental Instruction (SI) is a 47-year old proven peer-learning model that addresses student engagement, performance and retention as well as the transition to Higher Education (HE). SI was developed at the University of Missouri Kansas City in the US and has received wide recognition. Today the method has practitioners all over the United States as well as in several other countries around th

Pollen analysis is an important tool in many fields, including pollination ecology, paleoclimatology, paleoecology, honey quality control, and even medicine and forensics. However, labour‐intensive manual pollen analysis often constrains the number of samples processed or the number of pollen analysed per sample. Thus, there is a desire to develop reliable, high‐throughput, automated systems. We p

This master thesis work concerns fault detection and isolation (FDI) of an electro-mechanical servo using analytical redundancy. The purpose is to reduce the number of sensors used in today's fault detection schemes and at the same time keep the level of redundancy in the system. The report will start with a comparison between physical and analytical redundancy. Whichever design method that is

Problem IKEA uses a standard store concept when building IKEA stores. Developing a standard store concept simplifies the procedure to build many similar stores in a more efficient way. However, a difficulty in the process of establishing and using a standardised concept is how to continuously update the concept itself. Today there are big differences in retail construction costs between different

This thesis explores the simplifications the chirality-flow formalism brings the calculations of scattering amplitudes in massless QED. We explain Feynman diagrams and chirality- flow diagrams to emphasize how the calculations of scattering amplitudes differ. It is studied how applying the chirality-flow formalism simplifies the calculations. The work focuses on calculations with and without exter

Efter att den svenska riksdagen beslutade att återuppta totalförsvarsplaneringen år 2015 har vi erfarit en världsomspännande pandemi, krig i Sveriges närområde samtidigt som en stundande klimatkris blir alltmer akut. Dessa faktorer har gjort civilförsvarsförmågan och den svenska befolkningens hemberedskap till en aktuell fråga. Hur väl förberedda är vi egentligen ifall samhällets service slutaSince the Swedish parliament decided to resume the total defense planning in 2015, we have experienced a worldwide pandemic, war in the vicinity of Sweden, and an impending climate crisis becoming increasingly urgent. These factors have put civil defense capabilities and the Swedish population´s home preparedness high on the political agenda. How well-prepared are we really if societal service

I Sverige lider de större städerna av bostadsbrist och i stor utsträckning segregation som bidrar till ökade klyftor mellan människor. Fler innovativa lösningar som uppmuntrar till en stadsutveckling som främjar integration genom att bryta segregationen efterfrågas därför. Syftet med uppsatsen är att analysera möjligheterna att, i Sverige, tillföra hyresbostäder riktade till en viss inkomstgrupp iAll the larger cities in Sweden suffer of housing shortage and widespread segregation that many times contribute to increased social gaps between people. More innovative solutions that encourage urban development that promote integration by breaking segregation are therefore demanded. The purpose of the paper is to analyze the possibilities in Sweden to supply rental housing targeted to a separate

The purpose of this thesis was to describe, interpret and compare the set of rules in Swedish civil law regarding repayment of unlawful transactions done before a Limited Company has become bankrupt. This paper is merely based on the rules of refunding according to the Bankruptcy Act and the rules invented to prevent illegal dividend of profit in limited companies according to the Limited Company

Problem definition: SPAGO Imaging AB is developing a new contrast agent for Magnetic Resonance Imaging (MRI). In approximately 5 years, the product will be launched on the market. The company is therefore about to look for investors to fund the development and growth. To gain investors interest, a clearly defined market for this sort of contrast agent is required. Purpose: The purpose of this thes

Formidabel is a function oriented company in the processed food industry. Due to rapid growth and an ever-changing market the company is constantly exposed to new challenges, and running the risk of loosing focus on its vision and goals. The company’s target market is predominantly small and middle sized organizations and its business concept consists of having great knowledge in market trends and

Sammanfattning Det är ett vanligt fenomen att webbplatser använder sig av cookies för att samla in information, vilken sedan säljs vidare till tredje part i marknadsföringssyfte. Denna teknik fungerar oberoende den fysiska personens geografiska placering i världen. Förfarandet väcker frågor om personlig integritet och individens möjligheter till skydd i ljuset av teknikutvecklingen. FramställningeIt is a common phenomenon that websites use cookies in order to collect information, which thereafter is being sold to a third party for marketing purposes. This technique works regardless of the natural person's geographical location in the world. The process raises issues in relation to privacy protection and the individual's protection in light of the technological development. The purp

Background Coronary artery disease is one of the most common causes of death. A common cardiac examination is to give a visualization of the myocardial blood flow by injecting a radio pharmaceutical and detect the radiation with a camera. The camera has for decades been using thallium doped sodium iodide (NaI(Tl)) as the detector material. New detector materials have been developed because of the

Popular science summary: Potential Distribution for the Endangered Asian Wild Ass Over the past century, large mammals have been globally under increasing pressure of humanized landscapes. Since extirpations of large herbivores are likely to have complicated consequences for the entire ecosystem, their conservation is a priority. With almost 81% threatened species, Perissodactyla (odd-toad ungu

This report focuses on CFD-calculations using parallel processors carried out with the software Fire Dynamics Simulator (FDS). From a users point of view the advantages and disadvantages with parallel CFD-calculations were analyzed and evaluated. A simplified me-thod for quantitative evaluation was developed with guidance from ASTM E 1355 whereu-pon relative differences between serial reference sc
