Apache ORC (Optimized Row Columnar) is a free and open-source column-oriented data storage format. [3] It is similar to the other columnar-storage file formats available in the Hadoop ecosystem such as RCFile and Parquet. It is used by most of the data processing frameworks Apache Spark, Apache Hive, Apache Flink, and Apache Hadoop.
The Ohio Revised Code (ORC) contains all current statutes of the Ohio General Assembly of a permanent and general nature, consolidated into provisions, titles, chapters and sections. [1] However, the only official publication of the enactments of the General Assembly is the Laws of Ohio ; the Ohio Revised Code is only a reference.
ORC Rating Officers. The 'Central Rating Office' establishes delegated Rating Offices [5] in each country with active offshore racing. Rating offices issue ORC International and ORC Club certificates and administer their national fleets [6] by supervising the measurement and rating of the yachts. For countries where a national Rating Office is ...
Cylinder-head-sector (CHS) is an early method for giving addresses to each physical block of data on a hard disk drive. It is a 3D-coordinate system made out of a vertical coordinate head, a horizontal (or radial) coordinate cylinder, and an angular coordinate sector. Head selects a circular surface: a platter in the disk (and one of its two ...
The functional part of the head is the round, orange structure in the middle. Also note the connection wires bonded to gold-plated pads. Read–write head of a 3 TB hard disk drive manufactured in 2013. The dark rectangular component is the slider and is 1.25 mm long. The platter surface moves past the head from right to left.
T-s diagram for the ideal/real ORC. The working principle of the organic Rankine cycle is the same as that of the Rankine cycle: the working fluid is pumped to a boiler where it is evaporated, passed through an expansion device (turbine, [3] screw, [4] scroll, [5] or other expander), and then through a condenser heat exchanger where it is finally re-condensed.
An adjustable spanner (UK and most other English-speaking countries), also called a shifting spanner (Australia and New Zealand) [1] or adjustable wrench (US and Canada), [a] is any of various styles of spanner (wrench) with a movable jaw, allowing it to be used with different sizes of fastener head (nut, bolt, etc.) rather than just one fastener size, as with a conventional fixed spanner.
The ORC is essential for the loading of MCM complexes onto DNA. This process is dependent on the ORC, Noc3, Cdc6, and Cdt1 – involving several ATP controlled recruiting events. First, the ORC, Noc3p and Cdc6 form a complex on origin DNA (marked by ARS type regions). New ORC/Noc3/Cdc6 complexes then recruit Cdt1/Mcm2-7 molecules to the site.
