Modélisation d'images agronomiques - application a la reconnaissance d'adventices par imagerie pour une pulvérisation localisée
2009
Plant (crop and weed) identification is a very active field of research in agriculture since the reinforcement of European laws about pesticide applications for a site-specific management of spraying practices. A new crop/weed simulation model was developed to allow the evaluation of crop/weed spatial identification methods from imaging. Considering multiples agronomic parameters – crop location, weed infestation rate, weed spatial distribution – the first step of this model allows the simulation of an infested crop field. Then, in a second step, a world to camera transformation is applied to allow every kind of picture (with or without perspective effect). The validation of this model was …
Full parallax three-dimensional display from Kinect v1 and v2
2016
We exploit the two different versions of Kinect, v1 and v2, for the calculation of microimages projected onto integral-imaging displays. Our approach is based on composing a three-dimensional (3-D) point cloud from a captured depth map and RGB information. These fused 3-D maps permit to generate an integral image after projecting the information through a virtual pinhole array. In our analysis, we take into account that each of the Kinect devices has its own inherent capacities and individualities. We illustrate our analysis with some imaging experiments, provide the distinctive differences between the two Kinect devices, and finally conclude that Kinect v2 allows the display of 3-D images …
Sobre la crítica hegeliana del criticismo
2000
El interés de Hegel por el giro llevado a cabo por Kant en la epistemología está motivado especialmente por las consecuencias negativas que tal giro ha tenido para la metafísica. En la medida en que un objetivo principal de Hegel es elevar la especulación al rango de ciencia o genuino saber, su proyecto filosófico implica una confrontación con el enfoque crítico de Kant. El objeto de este ensayo es examinar la naturaleza y alcance de tal confrontación, tratando de mostrar las consecuencias que ésta tiene para Hegel en lo que respecta, no sólo a la viabilidad de su propio programa especulativo, sino también a su valoración de la filosofía crítica.
Rosyjski korpus posiłkowy (auksyliarny) na służbie Augusta II w Rzeczypospolitej i Saksonii. Nowe spojrzenie na sasko-polsko-rosyjską współpracę poli…
2019
Polityczno-militarna współpraca sasko-polsko-rosyjska od początku wielkiej wojny północnej (1700–1721) nie układała się po myśli Augusta II, który ponosił klęski w starciach z wojskami Karola XII i po przegranej Piotra I pod Narwą w 1700 roku wziął na siebie główny ciężar wojny. Próbą wspomożenia armii saskiej Augusta II przez cara, który obawiał się zawarcia przez władcę sasko-polskiego separatystycznego pokoju z królem szwedzkim, i chciał także zaangażowania w konflikt Rzeczypospolitej, było zorganizowanie rosyjskiego korpusu posiłkowego (auksyliarnego), który z perspektywy czasu okazał się zabiegiem politycznym, a w mniejszym stopniu wojskowym. W zaprezentowanym artykule recenzyjnym prob…
Vēsturiskā kamera herbāriju ievākšanai
2019
19. gadsimtā par botāniķu lauka darbu ierastu aprīkojumumu kļuva no metāla izgatavota kamera herbārija uzglabāšanai (‘vasculum’). Latvijas Universitātes Muzeja Botānikas un mikoloģijas kolekcijās glabājas ne tikai šādas kameras lietojuma liecības fotogrāfijās, bet arī pati kamera.
Karla Reinholda Kupfera herbāriju saraksts
2019
1929. gadā dabaspētnieks Karls Reinholds Kupfers (1872 – 1935) pārdeva Latvijas Universitātei savu herbāriju, kas bija izvietots skapjos, kam klāt bija kolektora sastādīts saraksts. Šobrīd LU Muzeja Botānikas un Mikoloģijas kolekcijās glabājas ne tikai šis aptuveni 26 700 lapu lielais herbārijs, kas veido Herbarium Balticum (starptautiskais kods RIG I), bet arī zinātnieka skapji, kuros izvietots K. R. Kupfera mantojuma apakškolekcija.
Marco Ivaldo, Libertà e moralità. A partire da Kant.
2010
Marco Ivaldo raccoglie in questo libro diversi contributi, comparsi autonomamente dal 1984 al 2007 in più riviste filosofiche: l'autore esamina alcuni nuclei della riflessione morale di Kant in una specifica direzione verso posizioni filosofiche successive, in particolare verso Fichte e la filosofia trascendentale contemporanea, con lo scopo di tematizzare un potenziale di questioni dell’etica kantiana per l’attuale comprensione del significato di un’etica in concreto.
Symmetries and Covariance of the Maxwell Equations
2012
Already within a given, fixed division of four-dimensional spacetime into the space where experiments are performed, and the laboratory time variable, Maxwell’s equations show interesting transformation properties under continuous and discrete space-time transformations. However, only the action of the whole Lorentz group on them reveals their full symmetry structure. A good example that illustrates the covariance of Maxwell’s equations is provided by the electromagnetic fields of a point charge uniformly moving along a straight line.
Dopant radial inhomogeneity in Mg-doped GaN nanowires
2018
International audience; Using atom probe tomography, it is demonstrated that Mg doping of GaN nanowires grown by Molecular Beam Epitaxy results in a marked radial inhomogeneity, namely a higher Mg content in the periphery of the nanowires. This spatial inhomogeneity is attributed to a preferential incorporation of Mg through the m-plane sidewalls of nanowires and is related to the formation of a Mg-rich surface which is stabilized by hydrogen. This is further supported by Raman spectroscopy experiments which give evidence of Mg-H complexes in the doped nanowires. A Mg doping mechanism such as this, specific to nanowires, may lead to higher levels of Mg doping than in layers, boosting the po…
Subtractive imaging in confocal scanning microscopy using a CCD camera as a detector
2012
[EN] We report a scheme for the detector system of confocal microscopes in which the pinhole and a large-area detector are substituted by a CCD camera. The numerical integration of the intensities acquired by the active pixels emulates the signal passing through the pinhole. We demonstrate the imaging capability and the optical sectioning of the system. Subtractive-imaging confocal microscopy can be implemented in a simple manner, providing superresolution and improving optical sectioning. (C) 2012 Optical Society of America
