Voluntad política para un tiempo de reformas: Presupuestos previos para abordar una reforma constitucional
2019
The vast majority of Spaniards is in favor of a constitutional reform. Before the undertaking of this reform, there are some previous conditions that need to be granted: a rational debate on ideas; a reduction of the political and social tension; a common goodwill to reach a consensus; and some loyalty during negotiations. As many other scholars, the author agrees that instead of talking about a constitutional reform, it would be more adequate to talk about some constitutional reforms, that should be undertaken gradually. He also stresses that these reforms do not imply the opening of a new constituent process. In addition, he underlines the fact that the Catalan crisis should not be the tr…

«Den dagen PC-en går i stykker, da er mye av min verden gått i stykker» : En kvalitativ studie om eldres bruk av Duka-PC
2019
Masteroppgave klinisk helsevitenskap ME520 - Universitetet i Agder 2019 Background:Information and communication technology (ICT) affects our everyday lives and the government wants it to be equal opportunities for everyone despite gender, age, background and economy. Many seniors want to be an active player in this digital everyday life. However, lack of knowledge and skills may affectthe confidence to get started. Technological solutions are needed that canmeet their needs and which are adjusted to the functional impairments the individual may have. The importance of facilitated training and user-friendly equipment can be of great value to achieve a greater degree of mastering and confide…
Biochar-pellets as substitute for fossil coal in metallurgical processes
2018
Master's thesis Renewable Energy ENE500 - University of Agder 2018 This thesis serves as a base for later research on substituting fossil coal and coke with biochar in the Norwegian metallurgical industry. Because Norwegian electricity production is almost entirely based on carbon dioxide - neutral hydropower, the nation’s main pollutant is fossil coal. Biochar serves as an alternative to coal but can currently only partially satisfy the quality requirements for use in top-loaded smelting facilities. With comparison to fossil coal, biochar has a higher price and a lower mechanical strength. A coupling of pyrolysis and pelletising is therefore investigated to obtain a sustainable product wit…
Residual Generator-Based Controller Design via Process Measurements
2014
Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2014/290371 This paper deals with designing the controller of LTI system based on data-driven techniques. We propose a scheme embedding a residual generator into control loop based on realization of the Youla parameterization for advanced controller design. Basic idea of the proposed scheme is constructing the residual generator by using the solution of the Luenberger equations as well as the well-established relationship between diagnosis observer (DO) and the parity vector. Besides, the core of the above idea is straightly using the process …
Metric learning method aided data-driven design of fault detection systems
2014
Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2014/974758 Fault detection is fundamental to many industrial applications. With the development of system complexity, the number of sensors is increasing, which makes traditional fault detection methods lose efficiency. Metric learning is an efficient way to build the relationship between feature vectors with the categories of instances. In this paper, we firstly propose a metric learning-based fault detection framework in fault detection. Meanwhile, a novel feature extraction method based on wavelet transform is used to obtain the feature ve…
Dynamic characterization for the dielectric electroactive polymer fundamental sheet
2012
Published version of an article published in the journal: International Journal of Advanced Manufacturing Technology. Also available from the publisher at: http://dx.doi.org/10.1007/s00170-012-4423-6 A study into the appropriateness of characterizing the dynamics of the dielectric electroactive polymer (DEAP) fundamental sheet has been performed. Whereby a model describing the dynamics of the DEAP fundamental sheet is developed, parameters of the models are determined using experimental/simulation results, and verification has been conducted to determine the precision of the dynamic model. The precision for the DEAP sheet-obtained dynamic model could not be verified unless some parameters c…
Hardware-in-the-loop implementation for an active heave compensated drawworks
2012
Published version of an article published in the journal: Central European Journal of Engineering. Also available from the publisher at: http://dx.doi.org/10.2478/s13531-011-0062-1 This paper presents the setup and running of a hardware-in-loop (HIL) simulation for an active heave compensated (AHC) draw-works. A simulation model of the draw-works is executed on a PC to simulate the AHC draw-works with a physical PLC. The PLC (ET200S) is configured with a controller architecture that regulates the motor angular displacement and velocity through actuation of the servo valves. Furthermore, a graphical user interface is developed for operation of the AHC system. The HIL test allowed tuning of t…
The harp: a vehicle crash test apparatus for full-scale crash test experiments
2012
Published version of an article in the journal: The International Journal of Advanced Manufacturing Technology. Also available from the publisher at: http://dx.doi.org/10.1007/s00170-012-3960-3 The current paper describes an apparatus for full-scale vehicle crash test experimentation. This apparatus is referred to as the harp. In brief, the harp may either accelerate a trolley which is impacted into a test vehicle or the test vehicle itself may be accelerated and impacted into an object such as a barrier, a pole, or another vehicle. If a trolley is accelerated, it is equipped with load cells to record the axial crushing force. If a test vehicle is accelerated, it is equipped with a three-ax…
First search for point sources of high-energy cosmic neutrinos with the ANTARES neutrino telescope
2011
Results are presented of a search for cosmic sources of high-energy neutrinos with the ANTARES neutrino telescope. The data were collected during 2007 and 2008 using detector configurations containing between 5 and 12 detection lines. The integrated live time of the analyzed data is 304 days. Muon tracks are reconstructed using a likelihood-based algorithm. Studies of the detector timing indicate a median angular resolution of 0.5 0.1deg. The neutrino flux sensitivity is 7.5 ¿ 10 -8(E ¿/ GeV) -2 GeV -1 s -1 cm -2 for the part of the sky that is always visible (¿ < -48deg), which is better than limits obtained by previous experiments. No cosmic neutrino sources have been observed.
