Hvordan kan teknologi skape nye undervisnings- og læringsmåter i fremmedspråksundervisningen fram mot 2030?
2014
Published version of an article in the journal: Acta Didactica Norge. Also available from the publisher at: http://adno.no/index.php/adno/article/view/358/393 Open Access I denne artikkelen drøfter jeg hvordan teknologi kan skape nye undervisnings- og læringsmåter i fremmedspråksundervisningen fram mot 2030. Jeg starter med å skissere et mulig framtidsscenario i form av et blogginnlegg skrevet av en 15 åring i året 2030. Videre i artikkelen tar jeg utgangspunkt i dette framtids-scenarioet og sammenligner det med dagens situasjon, i tillegg til at jeg drøfter hva som må til for at scenarioet kan oppfylles. Læreren spiller en nøkkelrolle i utviklingen av nye undervisnings- og læringsmåter, og…
Simulation analysis of Ruthenium-based Dye Sensitized Solar Cells
2016
Dye Sensitized Solar Cell (DSSC), usually referred as one of the most promising third generation photovoltaic devices, is an electrochemical device in which a molecule (i.e., the dye) chemisorbed onto the surface of a porous material absorbs the incident light and, thus, transfers an electron to the wide band gap semiconductor material. The injected electrons can diffuse through the semiconductor up to the collecting anode without the risk of recombination. The roles of the electrolyte which permeates the cell are to regenerate the ionized molecule and to implement a hole-transporting layer, allowing to repeat the abovementioned process. Thanks to this behaviour, semiconductors with large a…
Electro-optical characterization of highly efficient Dye-Sensitized solar cells
2015
Nowadays, a growing demand for free and clean energy requires the study and the development of new low-cost solar photovoltaic (PV) cells. Among them, Dye Sensitized Solar Cells (DSSCs) based on ruthenium complexes as sensitizers are assuming a great importance. The DSSCs under study are composed placing in succession a transparent conductive glass on which is screen-printed a mesoporous TiO2 thin film sensitized by a ruthenium based dye (N719), an electrolytic solution containing a redox couple (I-/I3-) and another conductive glass covered by a thin transparent catalyst platinum film. In this work, we have measured the main photoelectrochemical parameters of the above mentioned DSSCs at di…
Laser Beam Induced Current measurements on Dye Sensitized Solar Cells and thin film CIG(S,SE)2 modules
2017
Calculating the efficiency of a solar cell depends on a precise knowledge of its area. Indeed, the photoresponse uniformity is essential to improve the manufacturing process. In this work we report on Laser Beam Induced Current measurements performed on CIG(S,Se)2 modules and Dye Sensitized Solar Cells. These measurements, performed via a green and a red HeNe lasers both operating at an optical irradiance of 1 Sun, allowed to obtain an accurate photoresponse map of the specimens and highlighted the non-uniformities with a spatial resolution of 400 μm and 80 μm, respectively.
Evaluation of Multispectral Data Acquired from UAV Platform in Olive Orchard
2023
Precision agriculture is a management strategy to improve resource efficiency, production, quality, profitability and sustainability of the crops. In recent years, olive tree management is increasingly focused on determining the correct health status of the plants in order to distribute the main resource using different technologies. In the olive grove, the focus is often on the use of multispectral information from UAVs (Unmanned Aerial Vehicle), but it is not known how important spectral and biometric information actually is for the agronomic management of the olive grove. The aim of this study was to investigate the ability of multispectral data acquired from a UAV platform to predict nu…
An Automatic Ontology-Based Approach to Support Logical Representation of Observable and Measurable Data for Healthy Lifestyle Management: Proof-of-C…
2020
Background Lifestyle diseases, because of adverse health behavior, are the foremost cause of death worldwide. An eCoach system may encourage individuals to lead a healthy lifestyle with early health risk prediction, personalized recommendation generation, and goal evaluation. Such an eCoach system needs to collect and transform distributed heterogenous health and wellness data into meaningful information to train an artificially intelligent health risk prediction model. However, it may produce a data compatibility dilemma. Our proposed eHealth ontology can increase interoperability between different heterogeneous networks, provide situation awareness, help in data integration, and discover…

2020
Estudiar la correlación entre valores de tomografía de coherencia óptica (OCT, Optical Coherence Tomography) peripapilar y macular con volumetrías cerebrales y espinales determinadas a partir de imágenes de resonancia magnética (RM), teniendo en cuenta el tipo de esclerosis múltiple (EM) y el antecedente de neuritis óptica (NO). Formular y validar modelos matemáticos para la predicción de la discromatopsia y de la discapacidad a partir de marcadores clínicos y paraclínicos. MATERIAL Y MÉTODO: Estudio observacional, analítico y transversal de 92 pacientes de la Unidad Mixta de EM y Neurorregeneración del Hospital Universitario y Politécnico La Fe de Valencia. De cada paciente se recogieron l…
Talentutvikling i fotball : kan et opplevd motivasjonsklima predikere behovstilfredsstillelse og selvregulert læring hos unge talentfulle fotballspil…

Masteroppgave i idrettsvitenskap - Universitetet i Agder 2016 Studies that have looked at the relationship between training and performance have sown that athletes must practice at lot in order to reach a high level (Côté et al., 2007; Ericsson et al., 1993; Simon & Chase, 1973), and motivation is viewed as an important factor in order to implement the required training. Through satisfaction of the basic needs of autonomy, competence and relatedness, athletes will feel self-determination and intrinsic motivation (Deci & Ryan, 1985). Furthermore, football players who spend more time promoting their own learning is often preferred over players taking less responsibility (Toering et al., 2012)…
Sekundāri progresējoši noritošas multiplās sklerozes riska faktori izvērtējot slimības norises formas un pielietoto terapiju
2016
Ievads: Multiplā skleroze ir viena no biežāk sastopamajām hroniskām neirodeģeneratīvām saslimšanām, kas progresējot pacientam izraisa darba nespēju un būtiski ietekmē pacienta dzīves kvalitāti. Darba mērķis: ir noskaidrot invaliditātes attīstības straujumu pacientiem ar sekundāri progresējošu multiplo sklerozi, atkarībā no slimības progresēšanas, saslimšanas vecuma, slimības ilguma, dzimuma un terapijas. Metodes un materiāli: Retrospektīva pētījuma ietvaros tika skatītas pacientu ambulatorās kartiņas ar sekundāri progresējošu multiplo sklerozi Latvijas Jūras Medicīnas Centra Latvijas Multiplās sklerozes centrā. Kopumā tika apskatītas 80 pacientu ambulatorās kartiņas no saslimšanas brīža līd…
