In this paper we present an investigation of to perform simultaneous measurements of the D/H-ratio by coincidence measurements using proton-proton scattering and proton-deuteron scattering or deuteron-deuteron scattering and deuteron-proton scattering. This is performed with the use of a double sided silicon strip detector (DSSSD), which provides both position information and energy information. T
Popular Abstract in Swedish Avhandlingen är uppdelad i två delar. Del I analyserar kapacitet för linjära modulationssystem med en bärvåg. Inom dessa system så skickas bitarna som en sekvens av pulser, där varje puls representerar en bit. När pulserna lanseras över kommunikationskanalen, så kommer de utsättas för reflektioner, interferens, och andra störningar. Kapaciteten är en övre gräns på antalThis thesis is divided into two parts. Part I analyzes the information rate of single antenna, single carrier linear modulation systems. The information rate of a system is the maximum number of bits that can be transmitted during a channel usage, and is achieved by Gaussian symbols. It depends on the underlying pulse shape in a linear modulated signal and also the signaling rate, the rate at whic
In this paper, we study and compare a number of subspace-based methods for determining the the number of sinusoids in noise. These are based on the subspace orthogonality and and shift-invariance properties that are known from the MUSIC (multiple signal classification) and ESPRIT frequency estimators. The method based on the orthogonality property has not previously appeared in the literature. We
Dark matter is an invisible type of matter believed to make up 85 % of the matter in the universe, but it has not yet been identified by experiments. According to certain particle physics theories, possible signatures of dark matter are so-called dark jets. They are the dark matter equivalent to classic jets, i.e collimated streams of particles. These jets could be produced from the proton-proton
15 credits The organism groups formerly known as Cryptogams – mosses, liverworts, lichen and fungi – are particularly diverse in Scandinavia. They are common and often dominant in a wide range of natural habitats. Therefore, Cryptogams have received much attention in practical conservation work during recent years. For example, so called ’signal species’ have been intensively used to identify ’key
Hur kommer framtidens matförsörjningssystem se ut? Hur bör den utformas så att allas behov av näringsrik och hållbar mat kan tillfredsställas på ett hållbart sätt? Är det rimligt att mat produceras på ett ställe och konsumeras på ett annat ställe? Är hållbar mat något som bara är förunnat de rika och de som har möjlighet att odla själva? En allt större del av Sveriges och världens befolkning bor d
Ongoing pollinator declines threaten the production of many entomophilous crops. Recent reports that yields of animal-pollinated crops in India are increasing less than pollinator-independent ones suggest the occurrence of pollen limitation. We experimentally evaluated if production of the common food crop chilli benefits from insect pollination and if crop production is constrained by lack of pol
Access to water is a necessity for farmers for them to be able to produce food. This poses a problem in Jordan, one of the world’s driest countries, but also in Sweden, where after a drought in the summer of 2018 the state of the water levels was more critical than ever. Virtual reality (VR) has shown to be a tool with a good effect on students’ learning. In this work VR has been taken advantage o
In this master's thesis, a copula approach is used to model the number of claims made by a customer holding three insurances. It is important for insurance companies to have good models for the risk proles of their customers, and the number of claims is a key element in calculating the expected cost for the company. Using copulas, multivariate distribution functions are allowed to have any des

Abstract in Norwegian Hovudlina i forskinga på lesing og skriving byggjer på tanken om at talt språk på alle vesentlege punkt er primært i høve til skrive språk. Omgrepsapparatet for studiet av språk og lese- og skrivedugleik er også bygd kring denne tanken. Dette er problematisk frå eit vitskapsteoretisk standpunkt sidan tanken om det talte språket sin dominans ikkje er tilstrekkeleg empirisk undMainstream research on reading and writing is based on the assumption, common in modern linguistics, that spoken language is primary to written language in most important respects. Unfortunately, the conceptual framework for the study of language and 'literacy' (encompassing both reading and writing skills) is built around this assumption. This is problematic with regard to the philosophy of scien

Ex-situ Raman spectroscopy is a well-established method for the structural characterization of soot but necessitates a sampling step before analysis is made. This work studied the potential to perform Raman spectroscopic measurements of soot directly in the combustion exhaust gases, i.e., online Raman measurements. Two types of soot were produced from a Mini-CAST soot generator, one immature with
In this paper, we consider a wireless communication system where a large intelligent surface (LIS) is deployed comprising a number of small and distributed LIS-Units. Each LIS-Unit has a separate signal process unit (SPU) and is connected to a central process unit (CPU) that coordinates the behaviors of all the LIS-Units. With such a LIS system, we consider the user assignments both for sum-rate a
The main aim with this master’s thesis was to study the possibilities of detecting an event (rat trap going off) by analyzing audio streams from a MEMS (micro-electromechanical systems) microphone or movement patterns from a MEMS accelerometer. To achieve this goal, a small, power efficient and cost efficient embedded system was built with the help of a development board, a MEMS accelerometer, a
We demonstrate a novel non-intrusive technique based on tunable diode laser absorption spectroscopy to investigate human maxillary sinuses in vivo. The technique relies on the fact that free gases have much sharper absorption features (typical a few GHz) than the surrounding tissue. Molecular oxygen was detected at 760 nm. Volunteers have been investigated by injecting near-infrared light fibre-op
