For example, a router's Gigabit Ethernet interface would require a relatively large 32 MB buffer. [4] Such sizing of the buffers can lead to failure of the TCP congestion control algorithm. The buffers then take some time to drain, before congestion control resets and the TCP connection ramps back up to speed and fills the buffers again. [5]
The Video Buffering Verifier (VBV) is a theoretical MPEG video buffer model, used to ensure that an encoded video stream can be correctly buffered, and played back at the decoder device. By definition, the VBV shall not overflow nor underflow when its input is a compliant stream, (except in the case of low_delay).
Kundt's tube is an experimental acoustical apparatus invented in 1866 by German physicist August Kundt [1] [2] for the measurement of the speed of sound in a gas or a solid rod. The experiment is still taught today due to its ability to demonstrate longitudinal waves in a gas (which can often be difficult to visualise).

Molecules flow into the tube (to the left) when the pressure in the tube is low (it is sucked into the tube via X 3, coming from the orifice and the buffer). Upon entering the tube, it has the temperature T H. Later in the cycle, the same mass of gas is pushed out from the tube again when the pressure inside the tube is high.
In 1925-1926 Svedberg constructed a new ultracentrifuge that permitted fields up to 100,000 g (42,000 rpm). [3] Modern ultracentrifuges are typically classified as allowing greater than 100,000 g. [4] Svedberg won the Nobel Prize in Chemistry in 1926 for his research on colloids and proteins using the ultracentrifuge. [5] [6] [3]
A framebuffer (frame buffer, or sometimes framestore) is a portion of random-access memory (RAM) [1] containing a bitmap that drives a video display. It is a memory buffer containing data representing all the pixels in a complete video frame . [ 2 ]
U-tube with piezo-electric actuator Digital density measuring principle. The oscillating U-tube is a technique to determine the density of liquids and gases based on an electronic measurement of the frequency of oscillation, from which the density value is calculated. This measuring principle is based on the Mass-Spring Model.
