Strength grading of Norway spruce side boards in the wet state was investigated. For a sample of 58 boards of dimensions 25×120×3000 mm3, density and dynamic modulus of elasticity in the axial direction, MOEdyn, were determined in the wet state. The boards were then split into two parts and the procedure of determining MOEdyn was repeated both before and after the boards were dried to a target
Correct time and frequency synchronization is important for the performance of orthogonal frequency division multiplex (OFDM) systems. We evaluate a system where a pseudonoise sequence (PN-sequence) is used for estimation of these synchronization parameters. The PN-sequence is superimposed on the OFDM signal. The system is evaluated by means of the variance of the frequency estimation error and th
Worldwide, information and communication technologies (ICT), particularly in the sense of digital literacy, are increasingly considered as both inevitable and indispensable parts of the school curriculum. Also, international student assessment studies like PISA have on several occasions assessed computer and information literacy. Additionally, classrooms, teaching and learning, as well as school a
In this study, low quality waste cooking oil with high total acid value, has been used for biodiesel production. The main factors affecting the reaction has been analysed using Response Surface Methodology (RSM). A quadratic model representing the interrelationships between reaction variables and free fatty acids (FFA) conversion has been developed. Analysis of variance (ANOVA) has been used for c
In this study, low quality waste cooking oil (WCO) with high total acid value has been used for biodiesel production. The main factors affecting the reaction have been analysed using Response Surface Methodology (RSM). A quadratic model representing the interrelationships between reaction variables and free fatty acids (FFA) conversion has been developed. Analysis of variance (ANOVA) has been used
In Ethiopia, full vaccination coverage among children aged 12–23 months has improved in recent decades. This study aimed to investigate drivers of the improvement in the vaccination coverage. The Oaxaca–Blinder decomposition technique was applied to identify the drivers using data from Ethiopian Demographic and Health Survey conducted in 2000 and 2016. The vaccination coverage rose from 14.3% in 2
An implementation of a self-tuning regulator is described. The regulator algorithm consists of two steps. Firstly the parameters of a model of the process are estimated in real time using the method of least squares. Secondly a minimum variance regulator based on the estimated parameters is computed at each sampling interval. Implementation of the algorithm on a process computer is discussed. Ques
Abstract: Pagan revivalism is a growing trend in the contemporary religious landscape. Is it possible to be a neopagan without disregarding the demands of reason? While outright belief in the old gods seems out of the question, I argue that polytheism represents a live epistemic possibility, and that non-doxastic paganism is therefore a viable option. However, the rational, non-doxastic neopagan s
This colloquium shares experiences from doing ethnographic fieldwork with young children and the challenges that followed due to the COVID-19 pandemic. The project DIGIKIDS Sweden has its focus on very young children (birth to three years) and their engagement with digital media technologies in their homes. The pandemic put the project on hold, but in the families where the fieldwork had already s
Measures of muscle mass, strength, and function predict risk of incident fractures, but it is not known whether this risk information is additive to that from FRAX (fracture risk assessment tool) probability. In the Osteoporotic Fractures in Men (MrOS) Study cohorts (Sweden, Hong Kong, United States), we investigated whether measures of physical performance/appendicular lean mass (ALM) by DXA pred
This bachelor thesis addresses women's trust in the Swedish judicial system in regard to sexual offences with the ultimate aim of detecting any differences in trust between the age groups of 18-21, 22-25 and 26-29 years old as well as district and city location and size. The outset for this was an internet-based survey, which was shared in two of the biggest Swedish Facebook groups for women.
The purpose of the thesis work is to investigate how contractors can involve environmental certification in the tender phase of a project and provide a basis for solutions to problems that may arise in environmental certification with CEEQUAL. CEEQUAL (The Civil Engineering Environmental Quality Assessment & Awards Scheme) is a certification system for assessing environmental issues and social
Syfte: Syftet med studien är att undersöka effekten av ett kartläggningsbesök med efterföljande telefonuppföljning på användande av kommunikationsstrategier och hörselrelaterad livskvalitet för individer med betydande hörselnedsättning (TMV4 60-69 dB HL på bättre örat). Metod: Ett kartläggningsbesök utformades där fokus låg på individen och dennes upplevda besvär kring den egna hörselnedsättningen
Overheating in buildings is becoming a major concern and cause for various health issues. Existing research and previous studies on the issue were examined to acquire relevant information about the definition of overheating, its possible causes, and the heath impacts it could have on human health. The review included data on the current status of thermal comfort and overheating regulations in Swed
Monte Carlo event generators are used by theoretical particle physicists to get a better understanding of the phenomena in particle physics. Given the improvements in precision and accuracy of event generators, using these tools can be very CPU intensive. A method of unweighting events using artificial neural networks is presented to improve the efficiency of event generation. An introduction to m
Plate tectonics is a unique feature of Earth, but its proposed time of initiation is still controversial, with published estimates ranging from ca. 4.2 to 0.7 Ga. Paleomagnetic data can provide a robust argument for one essential aspect of plate tectonics: large-scale relative lateral motions of distinct, rigid crustal blocks. Previously, the oldest relative horizontal motion between two or more b
