Apache Airflow is an open-source workflow management platform for data engineering pipelines. It started at Airbnb in October 2014 [2] as a solution to manage the company's increasingly complex workflows. Creating Airflow allowed Airbnb to programmatically author and schedule their workflows and monitor them via the built-in Airflow user ...
Native American flute. The Native American flute is a musical instrument and flute that is held in front of the player, has open finger holes, and has two chambers: one for collecting the breath of the player and a second chamber which creates sound. The player breathes into one end of the flute without the need for an embouchure.
The Apache (/ əˈpætʃi / ə-PATCH-ee) are several Southern Athabaskan language –speaking peoples of the Southwest, the Southern Plains and Northern Mexico. They are linguistically related to the Navajo. They migrated from the Athabascan homelands in the north into the Southwest between 1000 and 1500 CE.
In engineering, airflow is a measurement of the amount of air per unit of time that flows through a particular device. It can be described as a volumetric flow rate (volume of air per unit time) or a mass flow rate (mass of air per unit time). What relates both forms of description is the air density, which is a function of pressure and ...
For the distinction between [ ], / / and , see IPA § Brackets and transcription delimiters. In phonetics, the airstream mechanism is the method by which airflow is created in the vocal tract. Along with phonation and articulation, it is one of three main components of speech production. The airstream mechanism is mandatory for most sound ...
Apache Flex, formerly Adobe Flex, is a software development kit (SDK) for the development and deployment of cross-platform rich web applications based on the Adobe Flash platform. Initially developed by Macromedia and then acquired by Adobe Systems , Adobe donated Flex to the Apache Software Foundation in 2011 [ 2 ] and it was promoted to a top ...
Apache and DAP mounts. The M230 Chain Gun is used on the MH-60L Direct Action Penetrator. It is also the Area Weapon System on the Boeing AH-64 Apache attack helicopter, mounted on the chin turret. It uses a 2 hp (1.5 kW) electric motor to fire 30 mm (1.2 in) linkless ammunition at a rate of 625±25 rounds per minute.
Passive cooling covers all natural processes and techniques of heat dissipation and modulation without the use of energy. [1] Some authors consider that minor and simple mechanical systems (e.g. pumps and economizers) can be integrated in passive cooling techniques, as long they are used to enhance the effectiveness of the natural cooling process.
