The short lifetime of spark plugs in heavy-duty truck and stationary engines has been a major concern in the relevant industry. In this thesis work a time-resolved approach to detect the evaporation erosion of Ni electrodes in electrical discharges was proposed, and multiple detection methods were used to study the spark discharge. Spectroscopic study of the discharge's emission illustrated th

The number of Smart Cities have evolved in recent years and the concept is expanding in cities worldwide. Smart Cities have many potential advantages but to achieve these advantages Smart Cities must protect security and individual privacy. Addressing existing challenges in certain areas becomes critical to achieve further improvement and security and privacy concerns are very important in the Sma

The present research aims to produce a theoretical framework that a

The 36-hectare large RWN Areal is located 2 km south of the city center of Neubrandenburg, Germany. What once was founded as a Torpedo Testing Facility during WWII, became a Military Repair Work Facility during the GDR government until 1990. After the German Reunification, the site has only served business and industrial purposes, but was more so neglected in the 2000s and became a blind spot ever

As our way of living exploits the resources of the earth and our energy use keeps on increasing, we are now facing a climate crisis never seen before in modern time. To face these consequences and try to ease the harm we need to transform our extraction and use of energy. The use of chemical energy carriers and fuel cells offers the possibility of a completely green solution for energy distributio

Denna studie tittar på hur användandet av molntjänster påverkar komplexiteten i IT-miljön. Studien tittar både på konsumenter av molntjänster och leverantörer av molntjänster. Genom intervjuer hittas flera områden hos respondenterna där komplexiteten i IT-miljön både ökat och minskat genom användandet av molntjänster. Områden där komplexiteten ökar är genom att fler system introduceras i IT-miljön

IT-branschen är föränderlig och under ständig utveckling. Det råder även stor kompetensbrist inom området, vilket skapar ett behov för att undersöka hur de kunskapskrav som finns på arbetsmarknaden ser ut. Syftet med uppsatsen är att ta reda på vilka krav på kunskap som arbetsmarknaden har på systemvetare och hur kraven har sett ut i tidigare studier. Uppsatsen bygger på teori om begreppen kunskap

The mechanisms behind the positive first day market-adjusted return of IPOs on the American and Canadian markets is examined from 2000 through 2018.

This paper examines the indirect effect housing plays in the monetary transmission mechanism (MTM) of consumption. This is done by following the method of Giuliodori (2005) and estimating structural vector autoregressive models (SVAR) for 16 developed countries, from the first quarter of 1970 to the last quarter of 2018. For each country, two Impulse response functions of two different SVARs are c

Bakgrund: Psykisk ohälsa bland barn och unga ökar i Sverige. Skolan är en av de miljöer som barn spenderar mycket tid i och forskning visar att detta kan påverka deras hälsa. Svenska skolor saknar idag modeller för att förstå och tolka barns svårigheter utifrån ett aktivitets- och delaktighetsperspektiv. Ny kompetens behövs i skolan och arbetsterapi skulle kunna vara ett komplement till elevhälsan

Vid beviljande av lagfart efter fastighetsköp beräknas stämpelskatt på det högsta beloppet av köpeskilling och taxeringsvärde från föregående år. Om aktuellt taxeringsvärde saknas ska jämförelsen istället, enligt 9 § i lagen om stämpelskatt vid inskrivningsmyndigheter, ske med ett intygat värde. Detta värdeintyg ska vara utfärdat av en sakkunnig och ange fastighetens marknadsvärde vid tidpunkten fWhen granted a title deed after the purchase of property, the stamp duty is based on the highest number of the purchase price and the tax assessment value from the previous year.

I städer finns det, något förenklat, bilgator och gågator. En sommargågata, däremot, är både ock. Den skapas genom att biltrafiken tillfälligt stängs av på en gata under sommarmånaderna vilket ger fotgängare tillgång till hela gaturummet. Den frigjorda ytan kan användas till verksamheter och restauranger som vill flytta ut i gatan, växter, bänkar, spel och lek, cykelställ och konstinstallationer. A summer street is created by temporarily closing the car traffic on a street during the summer months. The pedestrians get access to the entire street and the liberated space can be used for activities, greenery, benches, bike parking, art and by restaurants. During recent years major cities have made the concept known to the general public. My study shows that summer streets have a much longer

Syftet med denna meta-analys var att belysa fenomenet hälsoångest, och mer specifikt att undersöka om de generella nivåerna av hälsoångest ökat under de senaste tre decennierna. Ledande forskare på området har spekulerat kring om en ökning föreligger, då utan egentligt empiriskt underlag. Den aktuella studien hade som syfte att utgöra en del av det empiriska underlag som krävs för att göra mer säkThe purpose of this meta-analysis was to shed light on the phenomenon of health anxiety, and more specifically to investigate whether the general levels of health anxiety has increased over the past three decades. Previous research in this area has speculated whether an increase exists, although without actual empirical evidence. The purpose of this study was to be a part of the empirical evidence
