Orbits Of Five Visual Binary Stars [PDF]
Baltic Astron.16:435-442, 2007, 2007 We presented here the orbital parameters for five visual binary stars calculated by using the new method which we named Sector Grid Search. Orbital parameters were obtained for the following stars: WDS 00152+2722 = ADS 195, WDS 02202+2949 = ADS 1780, WDS 11550$-$5606 = HIP 58106, WDS 16256$-$2327 = ADS 10049 and WDS 16256$-$2327 = ADS 10045.

RGB-D SLAM Combining Visual Odometry and Extended Information Filter
Sensors, 2015 In this paper, we present a novel RGB-D SLAM system based on visual odometry and an extended information filter, which does not require any other sensors or odometry.

Visual minima timings of eclipsing binaries: To use or not to use? [PDF]
arXiv, 2012 Plenty of mid-eclipse timings of short-periodic eclipsing binaries derived from series of visual observations appear to be an acceptable source of information for orbital period analyses, namely if they were done in time-intervals not covered by other types of observations. However, our thorough period analysis of the nearly contact eclipsing binary BS

Corticostriatal activity related to performance during continuous de novo motor learning
Scientific ReportsCorticostriatal regions play a pivotal role in visuomotor learning. However, less research has been done on how fMRI activity in their subregions is related to task performance, which is provided as visual feedback during motor learning. To address this,

A High-resolution Imaging Survey of Massive Young Stellar Objects in the Magellanic Clouds
The Astrophysical JournalConstraints on the binary fraction of massive young stellar objects (mYSOs) are important for binary and massive star formation theory. Here, we present speckle imaging of 34 mYSOs located in the Large Magellanic Cloud (1/2 Z _⊙ ) and Small Magellanic ...

Spectroscopic subsystems in nearby wide binaries [PDF]
arXiv, 2015 Radial velocity (RV) monitoring of solar-type visual binaries has been conducted at the CTIO/SMARTS 1.5-m telescope to study short-period systems. Data reduction is described, mean and individual RVs of 163 observed objects are given. New spectroscopic binaries are discovered or suspected in 17 objects, for some of them orbital periods could be ...

Document watermarking scheme for information tracking
Tongxin xuebao, 2008 A digital watermarking scheme for binary document image was proposed.First,a binary document image was segmented into individual characters.Then,based on the multiplicative transformation model,watermark was embedded by flipping the boundary points of ...

Astrometric Binaries in the Age of the Next Generation of Large (Space) Telescopes [PDF]
arXiv, 2005 I analyze several catalogs of known visual and spectroscopic binaries and conclude that a large number of binaries is missing in current catalogs. Samples of the best studied (nearby and bright) stars indicate that the true binary fraction may be as high as 95%. A preliminary analysis indicates that these binaries can a ect the astrometry signicantly.
