Deep-learning based reconstruction of the shower maximum X max using the water-Cherenkov detectors of the Pierre Auger Observatory
2021
The atmospheric depth of the air shower maximum $X_{\mathrm{max}}$ is an observable commonly used for the determination of the nuclear mass composition of ultra-high energy cosmic rays. Direct measurements of $X_{\mathrm{max}}$ are performed using observations of the longitudinal shower development with fluorescence telescopes. At the same time, several methods have been proposed for an indirect estimation of $X_{\mathrm{max}}$ from the characteristics of the shower particles registered with surface detector arrays. In this paper, we present a deep neural network (DNN) for the estimation of $X_{\mathrm{max}}$. The reconstruction relies on the signals induced by shower particles in the groun…
Emulation of Sun-Induced Fluorescence from Radiance Data Recorded by the HyPlant Airborne Imaging Spectrometer
2021
The retrieval of sun-induced fluorescence (SIF) from hyperspectral radiance data grew to maturity with research activities around the FLuorescence EXplorer satellite mission FLEX, yet full-spectrum estimation methods such as the spectral fitting method (SFM) are computationally expensive. To bypass this computational load, this work aims to approximate the SFM-based SIF retrieval by means of statistical learning, i.e., emulation. While emulators emerged as fast surrogate models of simulators, the accuracy-speedup trade-offs are still to be analyzed when the emulation concept is applied to experimental data. We evaluated the possibility of approximating the SFM-like SIF output directly based…

Improving the Use of Simulation in Nursing Education: Protocol for a Realist Review
2020
BackgroundNursing education has evolved in line with societal needs, and simulation-based learning (SBL) is increasingly being used to bridge the gap between practice and education. Previous literature reviews have demonstrated the effectiveness of using SBL in nursing education. However, there is a need to explore how and why it works to expand the theoretical foundation of SBL.ObjectiveThis review aims to understand how, why, and in what circumstances the use of simulation affects learning as part of the bachelor’s program in nursing.MethodsA realist review will be conducted in accordance with the realist template for a systematic review. In particular, we will identify and explore the un…
A Multi-Projector Calibration Method for Virtual Reality Simulators with Analytically Defined Screens
2017
The geometric calibration of projectors is a demanding task, particularly for the industry of virtual reality simulators. Different methods have been developed during the last decades to retrieve the intrinsic and extrinsic parameters of projectors, most of them being based on planar homographies and some requiring an extended calibration process. The aim of our research work is to design a fast and user-friendly method to provide multi-projector calibration on analytically defined screens, where a sample is shown for a virtual reality Formula 1 simulator that has a cylindrical screen. The proposed method results from the combination of surveying, photogrammetry and image processing approac…
Evaluation and Self-Evaluation in Simultaneous Translation: Assessments Methods
2012
Abstract The nature of evaluation and self-evaluation in simultaneous interpretation is based on the close connection between the main text (the version proposed by the speaker) and the interpreter's version. Between these two elements a number of variables emerge, that can damage the efficiency and the accuracy of simultaneous interpretation. The intention of our study is to propose a set of scientific methods and tools in order to offer to the interpreter the possibility of a self-assessment and the benefit of an appropriate evaluation of his work. In order to achieve these goals we used several methods, including experiments, case studies, questionnaires, evaluation scales. Research subj…
Existence of two solutions for singular Φ-Laplacian problems
2022
AbstractExistence of two solutions to a parametric singular quasi-linear elliptic problem is proved. The equation is driven by theΦ\Phi-Laplacian operator, and the reaction term can be nonmonotone. The main tools employed are the local minimum theorem and the Mountain pass theorem, together with the truncation technique. GlobalC1,τ{C}^{1,\tau }regularity of solutions is also investigated, chiefly viaa prioriestimates and perturbation techniques.
Analysis and evaluation of the inclusive model in infant and primary centre support systems
2016
En esta investigación se analiza el funcionamiento y la organización de los sistemas de apoyo utilizados en centros de Educación Infantil y Primaria de la Comunidad Valenciana. Planteamos hasta qué punto los sistemas de apoyo en estos centros contribuyen a mejorar la organización de un sistema inclusivo que resulte accesible para todos. En el estudio de casos han participado 24 profesionales pertenecientes a cuatro centros que tienen diferentes modalidades de escolarización. Para la recogida de información, se han manejado instrumentos cualitativos como son la entrevista, la observación y el análisis documental. Según los datos obtenidos, los sistemas de apoyo no se ajustan de forma integra…
Menetelmät monitieteellisen tutkimuksen haasteena
2010
Pääsääntöisesti jokaisella tieteenalalla on omat kiinnostuksen kohteensa, tutkimusmenetelmänsä sekä terminologiansa. Tutkimuksen sijoittuessa aihepiiriltään useamman tieteenalan puitteisiin, on luontevaa lähestyä ongelmaa hyödyntäen näitä tutkimustraditioita. Käytän tässä esimerkkinä kasvatustieteen väitöskirjaani ”Sananlaskut kasvatuspuheessa – perinnettä, kasvatusta, indoktrinaatiota?” vuodelta 2008. Sananlaskututkimus on siinä sekä teoreettisesti että menetelmällisesti varsin keskeisessä asemassa.
Developing doctoral students' / researchers’ understanding of the journal peer-review process
2021
A growing body of knowledge has confirmed that the journal peer-review process is an integral part of the scientific publication process and provides demonstrable benefits to journal editors and authors. This study aims to develop doctoral students’ understanding of the journal peer-review process and highlight the most common errors and pitfalls reviewers identify in novice authors’ manuscripts, which could lead to rejection. A qualitative content analysis research method was used to analyse the primary data as experience collected from senior researchers, editors and associate editors. Among the major contributions of this study is an interactive diagram that provides an overview of the j…
