Popular Abstract in Swedish Projektet har for avsikt att vardera den elektriska overledningen mellan hjartats formak och hur forsamring av denna overledning bidrar till uppkomsten av attackvis pakommande formaks- flimmer. Studierna har anvant sig av ekg- registreringar fran kroppsytan, registreringar fran hjartats insida, anatomiska dissektionsstudier och djurexperiment. Slutsatser 1. OfiltreratThe aim of this thesis was to evaluate the role of interatrial conduction defects in the genesis of lone paroxysmal atrial fibrillation (AF) using combined approach of non-invasive signal-averaged P-wave ECG, invasive electrophysiological (EP) studies, anatomical studies and animal experiments. Non-filtered signal-averaged P-wave ECG revealed irregularities in orthogonal P-wave morphology and the

Atrial fibrillation is the most common cardiac arrhythmia that demands medical attention. Computer-based detailed analysis of cardiac electrical signals from healthy subjects and patients with a history of atrial fibrillation has become an important tool in the further clarification of this disease. The aim of this study was to explore supraventricular conduction using the following selected techn

When being in a noisy environment, a normal hearing person can manage to sort out background noise and focus on the attended source. This is something that a person with impaired hearing will struggle with, even when wearing a hearing aid. Research for developing intelligent hearing aids has not yet come up with a solution for solving this problem and more research is needed. This thesis uses data

The soot emissions from diesel engines are much higher in transient operation than during steady state operation. In this thesis, a method for estimating the soot mass flow emission in transient drive cycles is presented. The proposed method uses stationary emission maps in combination with step responses. Bandpass filters are used to filter the engine torque/power to provide transient detection a

Syftet med detta examensarbete är att utreda vilka hinderdetekteringssystem som finns tillgängliga idag eller som är under utveckling, och att ta reda på vilket system som är bäst ur ett tekniskt och samhällsekonomiskt perspektiv. Med hinderdetektering menas de system som finns på järnvägen för att detektera var på järnvägen det finns ett hinder. Det kan t.ex. vara ett tåg, en godsvagn eller ett The main purpose of this thesis is to investigate which track vacancy detection systems are available today or under development, and determine which system is best from a technical and economically perspective. Track vacancy detection systems exist to supervise the railway and indicate if a track section is occupied with an obstacle, e.g. a train, freight wagon or maintenance vehicle. These trai

Syftet med detta examensarbete är att pressentera ett antal tekniska lösningar för att förbättra säkerheten och kapaciteten i ställverk 59. Ställverk 59 är den vanligaste ställverkstypen på Trafikverkets järnvägsnät. Grundkonstruktionen är utvecklad på 1950-talet, men ställverkstypen nybyggs fortfarande trots konstruktionens ålder. Ända sedan järnvägen infördes har det funnits behov av att styra t

Assistive Technologies offer the possibility to develop services aimed at improving the Quality of Life of patients and caregivers. Specifically, this work refers to the case of persons with dementia who can live in their homes but need to be assisted. This paper describes a monitoring kit that provides alarms to the caregiver in case of dangerous situations or unusual events detected by the senso

The building permit is usually the final decision of urban governance for public authorities, whereby the private actor is given the right to construct at the urban plot. But in urban areas there is an urban context, which calls the attention to the need of a planning perspective of the assembled built environment. Detailed plans are required, and they ought to be considered in a total urban or mu

Proton-detected NMR diffusion and P-31 NMR chemical shifts/bandwidths measurements were used to investigate a series of liposomal formulations where size and PEGylation extent need to be controlled for ultrasound mediated drug release. The width of the P-31 line is sensitive to aggregate size and shape and self-diffusion H-1 NMR conveys information about diffusional motion, size, and PEGylation ex

This report presents combinatorics studies in the search for a resonance of below 800GeVwhich decay product is a pair of hadronic jets from quarks. The resonance, predicted as a dark matter mediator, has couplings to dark matter particles as well as quarks and gluons. The resonance is created in association with a radiated object that can be either a photon or a jet. In the case of the radiation b

Advancement of technology with the aid of new application, wireless communication has grown rapidly in the past two decades. Recently, in the wireless communication industry, Narrowband- Internet of Things (NB-IoT) is being discussed by everyone, as the most important emerging technology of the day. Being a wireless technology, owing to the exodus of devices to be connected, with due consideration

The objective of this thesis is to reduce the alarms in the control rooms of the processing industry and to investigate a strategy for working with the alarms. The problem with the alarms in the automation system is a result of the highly automated production and failure to design the alarms for the operator. The situation analysis showed problems with badly tuned alarms and cascade of alarms. The

As one of the most important texts of the apostle Paul, Galatians offers a goodstarting-point for an investigation of Paul’s argumentation. The letter is polemical and contains a substantial amount of argumentative passages. Paul evidently wanted to persuade by using the best arguments possible to convince his addressees. Although the argumentation of Paul is often an issue within New Testament ex

Two-dimensional laser-induced incandescence (LII) measurements usually involve the use of a cylindrical lens to illuminate the planar region of interest. This creates a varying laser fluence and sheet width in the imaged flame region which could lead to large uncertainties in the quantification of the 2D LII signals into soot volume fraction distributions. To investigate these effects, 2D LII meas

In 1974, Sweden won the Eurovision Song Contest with ABBA’s song Waterloo. ABBA is still one of the best-known names in Swedish pop, alongside others such as Max Martin and Avicii. The same year saw the birth of Swedish cultural policy as a coherent and distinct national policy area, explicitly supporting inhabitants’ access to culture beyond the commercial market. Sweden is still one of the prima

The rapid development of current information technology has brought about new aspirations in the academic world, especially in higher education organizations. Learning management systems (LMS) are software applications or Web-based technology used mainly for digital learning and studying.
