Abstract The greatest source of hazardous airborne particles in an urban environment comes from traffic exhaust. Air pollution has a great impact on human health; estimated to cause 1.3 million deaths worldwide per year. About half of all mortality caused by air pollution can be linked to motorized traffic. There are several other sources that contribute to our polluted environment; from both natu
European Spallation Source (ESS) is a linear particle accelerator planned to be built in Lund, Sweden. There is a need to control the electric field in the cavities in the particle accelerator, according to given specifications of the field. The aim of this thesis is to compare a traditional PI controller to an MPC controller, to see if there is any difference in the performance that can be achiev
The aim of this thesis was to develop a general solution for a winder application by examining the possibility to control the spreader axis movement with an electronic cam. The electronic cam synchronizes the spreader axis with the winder axis by determining where the spreader axis should be positioned in relation to the winder axis position. A prototype was built to recreate the application scena
Based on the characteristics of economic growth in China's transition period, this paper builds a theoretical model based on Barro model, and analyzes the influence of local government expenditure and opening up to the consumption of residents. After that, this study will use China's interprovincial panel data from 2012 to 2016 to establish panel data model to test the impact of local gove
This thesis aims to evaluate the fire safety in special accommodations in Sweden. A survey was carried out along with interviews involving the regular staff of the special accommodations. It was found that special accommodations for the elderly suffering from dementia have the lowest share of personnel during the night that can help with evacuation in relation to individuals in need of physical he
We live in a busy world, where the demand of ready-to-eat (RTE) salad products has increased rapidly in a relatively short time. Despite of being an easy and fast way to add more vegetables to the daily diet, RTE salads have a serious underlying risk and the amount of vegetable-derived foodborne disease outbreaks has been increasing. The aim of the present study is to protect plants against contam
This paper presents a stochastic model for Meningococcal disease. Mathematical models for diseases are an important tool in population dynamics, and their results carry real-world implications as they guide policies and vaccination strategies. While the systems being modelled are generally stochastic in nature, deterministic models are often used, possibly to the detriment of accuracy. In this pro
The purpose of this thesis is to differentiate between the usage of three very similar Japanese conditionals: nara, nonara, and nodattara. A questionnaire study to find connections between the choice of conditionals depending on the surrounding expressions was conducted to establish potential rules and patterns of usage. The research found that short sentences, negative protases, and conditionall
Shopping for second-hand clothes is a phenomenon that has been on the rise, especially for the last twenty years. Second-hand clothes (SHC) consumption is a consumer-generated shopping trend whose consumers are discursively creating new identity meaning(s) for themselves out of their consumption. It has changed the outlook to become a fashionable trend in the last 20 years and is positively influe
Internationell investeringsrätt är ett mycket komplext rättsområde som består av cirka 3000 internationella investeringsavtal som syftar till att främja och skydda utländska investeringar. De tillhandahåller en tvistlösningsmekanism kallad investor-state dispute settlement (ISDS) mellan investerare och stater som ger investerare rätt att stämma värdstater direkt inför internationella skiljedomstolInternational investment law (IIL) is a highly complex area of law that consists of around 3000 international investment agreements (IIAs) that aim to promote and protect foreign investment. They provide for investor-State dispute settlement (ISDS) which gives investors the right to sue host States directly through international arbitral tribunals. During the last decade, this system has received
Det svenska straffrättsliga systematiken är uppbyggt så att den som uppfyller rekvisiten i en brottsbestämmelse är ansvarig i strikt gärningsmannaskap. Men för ett tillfredsställande system krävs det att även andra involverade personer kan tillskrivas straffansvar vilket löses genom medverkansansvaret. Uppsatsen syftar till att utreda hur långt gärningsmannaskapet och medverkansansvaret sträcker sThe Swedish criminal law system is structured so that those who meet the necessary conditions in a criminal provision are liable as perpetrators. But for a satisfactory system, it is required that other people involved also can be attributed criminal liability, which is solved through the responsibility for complicity. This thesis aims to investigate the range of the perpetration and responsibilit
Warehouses are critical nodes in a supply chain, providing a valuable interface between supply and demand. One aspect that warehouse operations struggle with is errors which, if not addressed, will impact the customers downstream from the warehouse. One of the ways to address errors in warehouses is through technology, such as automation of processes, though these are not always effective. A new t
Security lighting plays a vital role for safe evacuation during an emergency such as power outage or a fire related incidence. Installing a security lighting system properly is more crucial for a horse riding facility for two reasons. Firstly, if a sports activity is ongoing at the exact moment of an emergency, the activity needs to be ended safely with the help of security lights to avoid injurie
This thesis examines the impact of secular stagnation and increasing debt levels on real long-term interest rates by estimating a SVAR model for the US, UK, and Sweden between 1902 and 2020. The results of this thesis emphasize the impact of slow productivity growth in the decline of real long-term rates since the mid-1980s, with the evidence being quite strong for the US and UK, and somewhat weak
This paper describes the development of a method based on measurements of the radar cross section (RCS) amplitude and phase in the forward direction to determine the extinction cross section for the 2.5 GHz - 38 GHz frequency range using the optical theorem. Forward RCS measurements are technically complicated due to that the direct signal has to be subtracted from the total signal at the receivin
The aim of this study is to further explore (a) the extent to which retailers deploy corporate social responsibility (CSR) best practices to ensure social and environmental sustainability in international supplier relationships and (b) the association between firm characteristics and the retailers’ CSR activities in the supply chain. As a first step, the study identifies eight best practices based
