DETERMINATION OF THE ORIENTATION OF THE ACCRETION COLUMNS IN MAGNETIC CATACLYSMIC VARIABLES

open access: greenOdessa Astronomical Publications, 2017
Methods for the determination of the orientation of accretion columns in magnetic cataclysmic variables based on the observations of the circular and linear polarization, X-Ray flux and profiles of emission lines are discussed.

Planar column collapse of elongated grains [PDF]

open access: yesEPJ Web of Conferences, 2021
The granular column collapse is a benchmark configuration for the study of granular flows in dry, saturated, and submerged conditions. The collapse sequence and resultant mobility is acknowledged to be controlled by the column aspect ratio, while grain ...

Column-oriented database management systems [PDF]

open access: yes2007 IEEE 23rd International Conference on Data Engineering, 2013
In the following thesis I will present column-oriented database. Among other things, I will answer on a question why there is a need for a column-oriented database. In recent years there have been a lot of attention regarding a column-oriented database, even if the existence of a columnar database management systems dates back in the early seventies of

Column-oriented storage techniques for MapReduce [PDF]

open access: yesProceedings of the VLDB Endowment, 2011
Users of MapReduce often run into performance problems when they scale up their workloads. Many of the problems they encounter can be overcome by applying techniques learned from over three decades of research on parallel DBMSs. However, translating these techniques to a Map-Reduce implementation such as Hadoop presents unique challenges that can lead ...

Experimental and numerical study on column-foundation connection through external socket

open access: yesJournal of Civil Engineering and Management, 2021
In practice, bridge foundations and pier columns are usually constructed with cast-in-place concrete. Precast columns are currently widely used in highway bridges in China, which can save construction time and improve concrete quality.
