Radial velocity data analysis with compressed sensing techniques [PDF]

, 2016
We present a novel approach for analysing radial velocity data that combines two features: all the planets are searched at once and the algorithm is fast.

Catalogue of Radial Velocities of Galaxies [PDF]

Symposium - International Astronomical Union, 1983
A catalogue of radial velocities of galaxies has been completed which lists all radial velocities published until the end of December, 1980, for galaxies in both the northern and the southern hemispheres.For each galaxy the catalogue provides R.A. and Declination, name(s) of the galaxy (NGC, IC, 3 CR, etc.), each known heliocentric radial velocity with

A Young Planet Search in Visible and IR Light: DN Tau, V836 Tau, and V827 Tau

, 2008
In searches for low-mass companions to late-type stars, correlation between radial velocity variations and line bisector slope changes indicates contamination by large starspots.

No planet for HD 166435 [PDF]

, 2001
The G0V star HD166435 has been observed by the fiber-fed spectrograph ELODIE as one of the targets in the large extra-solar planet survey that we are conducting at the Observatory of Haute-Provence.

Data‐driven forecasting of ship motions in waves using machine learning and dynamic mode decomposition

International Journal of Adaptive Control and Signal Processing, EarlyView.
Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.

Structure of turbulent velocity field in the discharge stream from a standard Rushton turbine impeller [PDF]

Chemical Industry and Chemical Engineering Quarterly, 2017
The radial discharge jet from a standard Rushton turbine was investigated by the Laser Doppler Anemometry (LDA) method. Several distances from the impeller blades (in the radial direction) were chosen for the measurement of axial profiles: all three ...

Detectability of Exoplanetary Transits from Radial Velocity Surveys

, 2007
Of the known transiting extra-solar planets, a few have been detected through photometric follow-up observations of radial velocity planets. Perhaps the best known of these is the transiting exoplanet HD 209458b.

The first orbital solution for the massive colliding-wind binary HD93162 (=WR25) [PDF]

, 2006
Since the discovery, with the EINSTEIN satellite, of strong X-ray emission associated with HD93162 (=WR25), this object has been predicted to be a colliding-wind binary system.

Random Learning Leads to Faster Convergence in ‘Model‐Free’ ILC: With Application to MIMO Feedforward in Industrial Printing

International Journal of Adaptive Control and Signal Processing, EarlyView.
The cost as a function of the number of experiments for a non‐symmetric 21×21$$ 21\times 21 $$ system. Four approaches are shown: the proposed stochastic conjugate gradient ILC (SCGILC) method (), deterministic conjugate gradient ILC (), stochastic gradient descent ILC () and deterministic gradient descent ILC ().

Optimisasi Waktu Tempuh Pada Multi-AGV Menggunakan Particle Swarm Optimization

Jurnal Ilmiah Teknik Industri, 2016
An algorithm for velocity planning on a continuous-curvature path of a pair of automated guided vehicles (AGVs) that minimizing its travelling time is presented. A class of 3-degree Bezier curves is used as basic form of the path.
