UAS BASED TREE SPECIES IDENTIFICATION USING THE NOVEL FPI BASED HYPERSPECTRAL CAMERAS IN VISIBLE, NIR AND SWIR SPECTRAL RANGES
2016
Abstract. Unmanned airborne systems (UAS) based remote sensing offers flexible tool for environmental monitoring. Novel lightweight Fabry-Perot interferometer (FPI) based, frame format, hyperspectral imaging in the spectral range from 400 to 1600 nm was used for identifying different species of trees in a forest area. To the best of the authors’ knowledge, this was the first research where stereoscopic, hyperspectral VIS, NIR, SWIR data is collected for tree species identification using UAS. The first results of the analysis based on fusion of two FPI-based hyperspectral imagers and RGB camera showed that the novel FPI hyperspectral technology provided accurate geometric, radiometric and sp…
Nonlinear Disorder Mapping Through Three-Wave Mixing
2010
We implement a simple and powerful approach to characterize the domain distribution in the bulk of quadratic ferroelectric crystals via far-field second-harmonic spectroscopy. The approach is demonstrated in a lithium tantalate sample with periodic electric field poling and random mark-to-space ratio.
Autonomous hyperspectral UAS photogrammetry for environmental monitoring applications
2014
Abstract. The unmanned airborne system (UAS) remote sensing using lightweight multi- and hyperspectral imaging sensors offer new possibilities for the environmental monitoring applications. Based on the accurate measurements of the way in which the object reflect and emit energy, wide range of affecting variables can be monitored. Condition for reliable applications is reliable and accurate input data. In many applications, installation of geometric and radiometric reference targets in the object area is challenging, for instance, in forest or water areas. On the other hand, UASs are often operated in very poor conditions, under clouds or under variable cloud cover. Our objective is to deve…
Problemy współczesnej genologii medialnej
2020
The paper is an attempt at clarifying the object of research into media genology, distancing itself from literary studies genology. In the era of convergence of mass media, we can observe a progress in the blurring of the border between information and journalism, which consequently changes the contemporary communicative convention. As a result, information services are often degraded and the sense of implementing ‘traditional’ indicators of mass media genres is questioned. The change of communicative convention in contemporary mass media requires, above all, the use of cultural context for its analysis, as it determines the methods of creating messages and means of receiving them. It also …
Patente de corso y La zona fantasma: estrategias argumentativas y (des)cortesía instrumental
2013
This study deals with the pragmatic-linguistic strategies used by enunciators (or enunciators-locutors), Javier Marías (La zona fantasma) and Arturo Pérez Reverte (Patente de corso). After a brief introduction on argumentative discourse and the opinion columns, the role of the enunciator and their attitude toward the direct and indirect addressee is analysed in detail. More precisely, the article will demonstrate how elements, including mode; neologisms; imperative; interrogative sentences and also the ‘instrumental (im)politeness’ (or ironic tone) support persuasive objective that this kind of discourse pursues. En este trabajo proponemos una reflexión sobre las estrategias pragmático-ling…
Assessing Rollover Criteria for EUAs and CERs
2014
This study discusses how to roll over European Union Allowances (EUAs) and Certified Emissions Reduction (CERs) futures contracts with different maturities. The aim is to elucidate whether or not the choice of rollover date is important when constructing EUAs and CERs continuous futures time series. We have applied five different methodologies to link the series and our findings indicate that return distributions do not significantly differ for the different criteria. This result has direct practical implications in the field of applied econometrics of carbon markets given that we prove that the selection of the simple last-day rollover methodology criterion has no downside not only in term…
Preguntas de comprensión audiovisual sobreimpresas: propuesta para el aprendizaje de segundas lenguas
2018
Las actividades de comprensión audiovisual son complejas, especialmente en una segunda lengua. Por un lado, existe un conflicto de atención visual entre ver un vídeo y realizar una tarea escrita simultáneamente. Por otro lado, prestar atención a la imagen, al audio, y a la actividad al mismo tiempo puede saturar la memoria de trabajo. En este artículo se describe una propuesta innovadora que puede ayudar a limitar esta complejidad en las áreas de la enseñanza y la evaluación de segundas lenguas: el uso de preguntas de comprensión audiovisual integradas en la imagen del vídeo en forma de subtítulos y sincronizadas con los fragmentos relevantes. La propuesta es el resultado de una investigaci…
Exponentiating derivations of quasi∗-algebras: possible approaches and applications
2005
The problem of exponentiating derivations of quasi∗-algebras is considered in view of applying it to the determination of the time evolution of a physical system. The particular case where observables constitute a properCQ∗-algebra is analyzed.
La web 2.0: una ventana abierta a la interculturalidad
2012
En los últimos años se han estado desarrollando varias perspectivas y maneras de abordar la enseñanza de lenguas extranjeras desde dos puntos de vista principales que se conjugan perfectamente. Por un lado, le damos una mayor importancia a la cultura desde varias perspectivas: una cultura tan observada, tanto desde de la lengua meta como desde el punto de vista de la cultura del alumno extranjero que aprende la lengua. Hemos aprendido que la enseñanza de la lengua es indisoluble de la cultura que la envuelve. Por otro lado, combinamos este axioma de trabajo con un instrumento que se ha revelado imprescindible en la enseñanza actual, nos referimos a las nuevas tecnologías y, más concretament…
La pedagogía de las multiliteracidades y la experiencia estética como elementos claves en la enseñanza y el aprendizaje de lenguas. Por la consolidac…
2019
En el contexto de una enseñanza de lenguas que forma parte de una educación integral en la que la lectura y los procesos interpretativos, emocionales y creativos juegan un papel central, el presente artículo presenta la evolución del concepto de literacidad y la valoración de la experiencia estética como objetivos educativos. La pedagogía de las multiliteracidades y la experiencia estética conforman un nuevo paradigma en la enseñanza de lenguas, que son ejemplificadas con tres experiencias centradas en la intertextualidad, la poesía experimental y la rutas literarias.
