O presente trabalho visa apresentar uma proposta de construção aproximada do movimento Marte, que gera para um observador na Terra formato laço em relação às estrelas distantes perspectiva sistema copernicano. Para tal, utilizaremos o conhecido software GeoGebra. Crescendo consideravelmente, está sempre sendo atualizado e chega a reunir fóruns grupos, contando sua plataforma com gigantesca vari...

The Nancy Grace Roman Space Telescope (Roman) is an observatory for both wide-field observations and coronagraphy that scheduled launch in the mid 2020's. Part of planned survey a deep, cadenced field or fields enable cosmological measurements with type Ia supernovae (SNe Ia). With pixel scale 0".11, Wide Field Instrument will be undersampled, presenting difficulty precisely subtracting galaxy ...

For over 40 years, remote sensing observations of the Earth’s oceans have yielded global measurements sea surface temperature (SST).With a resolution approximately 1 km, these data trace physical processes like western boundary currents, cool upwelling at eastern and formation mesoscale sub-mesoscale eddies. To discover fundamental patterns SST on scales smaller than 10 we developed an unsuperv...

We present "Extending the Satellites Around Galactic Analogs Survey" (xSAGA), a method for identifying low-$z$ galaxies on basis of optical imaging, and results spatial distributions xSAGA satellites around host galaxies. Using spectroscopic redshift catalogs from SAGA Survey as training data set, we have optimized convolutional neural network (CNN) to identify $z < 0.03$ more distant objects u...

We studied the motility of filamentous mat-forming cyanobacteria consisting primarily of Oscillatoria-like cells growing under low-light, low-oxygen, and high-sulfur conditions in Lake Huron's submerged sinkholes using in situ observations, in vitro measurements and time-lapse microscopy. Gliding movement of the cyanobacterial trichomes (100-10,000 μm long filaments, composed of cells ∼10 μm wi...

This paper describes a domain independent approach to multiple class rotation invariant 2D object detection problems. The approach avoids preprocessing, segmentation and specific feature extraction. Instead, raw image pixel values are used as inputs to the learning systems. Five object detection methods have been developed and tested, the basic method and four variations which are expected to i...

Introduction Polymer gel dosimeters offer a practical solution to 3D dose verification for conventional radiotherapy as well as intensity-modulated and stereotactic radiotherapy. In this study, EGSnrc calculated and PAGAT polymer gel dosimeter measured dose profiles from single shot irradiation with 18 mm collimator of Gamma Knife in homogeneous and inhomogeneous phantoms were compared with eac...

Generative Models for 2-D images of 3-D scenes Anitha Kannan Doctor of Philosophy Graduate Department of Computer Science University of Toronto 2007 This thesis introduces generative models of appearance for analyzing 2D images of 3D visual scenes. Many 2D images contain multiple objects, where image components corresponding to each object undergo deformations, eg., due to changes in the shape ...

We investigate the radio emission of ∼ 185,000 quiescent (optically unclassifiable) galaxies selected from the Sloan Digital Sky Survey (SDSS). By median-stacking FIRST cutouts centered on the optically-selected sources, we are able to reach flux densities down to the 10s of μJy. The quiescent galaxy sample is composed of two subgroups inhabiting vastly different regimes: those targeted for the...
