This experimental study was conducted in an upper secondary school in the south of Sweden. The aim was to examine whether singing could act as a tool for improving English pronunciation among Swedish learners in the ages 16-17. The experiment consisted of three parts: a pre-test, a singing session and a post-test. There were one experiment group and one control group in order to compare and analyz
Efterfrågan på nybyggnation och behovet av infrastruktursatsningar är en ständig och stor uppgift som kommuner och andra myndigheter arbetar med. Stora krav ställs på att samhällsplaneringen ska ske utifrån ett långsiktigt hållbart perspektiv. Att intensiva och omfattande regn har blivit allt vanligare på senare tid resulterar i att samhällsplaneringen måste anpassas därefter, och flödesanalyser oThe government and municipalities of Sweden are responsible for the huge task of meeting the need of constructional and infrastructural investments. While planning and managing the land they are required to do so with long term perspectives. As intense and voluminous downpours have become common lately, the city planning and land management have to be adapted to this, which leads to flow analyses
Introduction The aim of this study is to determine the locations for school construction in two isolated mountainous communities in Gorno-Badakhshan Autonomous Oblast (GBAO) – Khorog and Porshnev towns. In recent decades, this region has become increasingly vulnerable to natural disasters. A major contributing factor to this vulnerability is the fact that very little land is available for human se
A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was succes
Three new cobalt complexes of the general formula [CoIII(L)Cl]2+, where L is one of five pentadentate nitrogen-donor ligands based on the N4Py framework, have been synthesized and characterized fully by UV−visible and NMR spectroscopies, high-resolution electrospray ionization mass spectrometry (HRESI-MS), X-ray crystallography, and electrochemistry. The electrocatalytic capabilities of these comp
Syftet med uppsatsen är att redogöra för faderskapspresumtionen samt att undersöka om det är en lämplig metod för att fastställa faderskap. Faderskapspresumtionen härstammar från den romerska rätten och innebär att om modern är gift vid barnets födsel, förutsätts hennes man vara barnets far. Är modern ogift fastställs faderskapet genom bekräftelse eller dom. Historiskt sett har faderskapspresumtioThe purpose this essay is to give an account of the presumption of paternity and to investigate whether it is a suitable method for establishing paternity. The presumption of paternity is a legal concept that generally assumes the husband to be the father of any child born during the marriage. The presumption has been a longstanding legal principle and originates from Roman law. If the mother is u
The goal of the Master Thesis is to upgrade the control of a power supply for a radar system. A controller based on Kalman filtering and state feedback has been developed for this two inputs two outputs system.
The purpose of this thesis is to further investigate the state of matter known as Quark-Gluon Plasma (QGP) that is produced in heavy ion collisions. This is done by analyzing jets and jet quenching in Pb-Pb collisions at $\sqrt[]{s_\textrm{NN}}$ = 2.76 TeV from ALICE. The events are discriminated by setting a 8 GeV/$c$ $p_\textrm{T}$ threshold on the trigger particle. This ensures that there is ha
Urbaniseringen innebär att det blir mer och mer hårdgjorda ytor i städer, vilket ökar belastningen på dagvattennätet. Vidare så innebär klimatförändringarna ytterligare utmaningar då nederbörden i Sverige antas öka. För att hantera detta föreslås hållbara dagvattenlösningar varav gröna tak kan vara en del. Detta skapar ett behov att på ett enkelt sätt modellera avrinningen från gröna tak. I detta The increasing urbanization means there are more and more impermeable surfaces in cities. This is straining the capacity of the stormwater network. Furthermore, climate change is assumed to bring about more precipitation in Sweden in the future. In order to deal with these challenges a sustainable approach to stormwater management is needed. Green roofs can be one part of the solution. This create
The NDVI time-series consist of trend, season and noise. Changes in the season component are related to climate factors and they happen gradually over long period of time. The changes in the trend component are often due to human activities, fires and etc. This paper implements two algorithms (PolyTrend and DBEST) in R language, in order to examine the vegetation changes in the Middle East and to
In applications of real time gesture detection on devices which have cameras and limited power supply it is important to consider both robustness and maintaining a low power consumption. A well explored approach is the use of cascades of boosted classifiers. As retraining is a very cumbersome process, online environment adaption would be an appealing approach to counter situations where the booste
