2.3 Pressure waves and cycles

In this section we shall be looking at the behaviour and properties of pressure waves in the atmosphere.

The prongs of the tuning fork move backwards and forwards cyclically. A cycle is a complete series of movements up to the point where the movement starts to repeat itself. As the prongs of the fork vibrate back and forth they push on neighbouring

Hadoop-Based Data Exploration for the Healthcare Safety Net—Technical and Sociocultural Challenges
About the Presentation The concept of mining large, heterogeneous data sets ("big data") to improve clinical outcomes and operational processes holds great promise for the healthcare industry.
