Comparison of video codecs. Α video codec is software or a device that provides encoding and decoding for digital video, and which may or may not include the use of video compression and/or decompression. Most codecs are typically implementations of video coding formats . The compression may employ lossy data compression, so that quality ...
Task 1: test takers describe a graph, table, chart, map, process, pie chart or diagram in their own words. Task 2: test takers discuss a point of view, argument, or problem. Depending on the task, test takers may be required to present a solution to a problem, present and justify an opinion, compare and contrast evidence, opinions and ...
Test subjects may have been invited instead of random sampling, resulting in sampling bias. Some countries may have significant height gaps between different regions. For instance, one survey shows there is 10.8 centimetres (4.3 in) gap between the tallest state and the shortest state in Germany.

The 6.0 system was a placement judging system. Judges awarded two marks in both the short program and free skate: one for technical merit and one for presentation, and each mark expressed as a number on a scale from 0 to 6.0. They were assessed in required elements for technical merit in the short program and could perform whatever elements ...
Bipolar transistors must be properly biased to operate correctly. In circuits made with individual devices (discrete circuits), biasing networks consisting of resistors are commonly employed. Much more elaborate biasing arrangements are used in integrated circuits, for example, bandgap voltage references and current mirrors.
In other cases, inequalities in healthcare reflect a systemic bias in the way medical procedures and treatments are prescribed for different racial and ethnic groups. Raj Bhopal, professor emeritus at University of Edinburgh, writes that the history of racism in science and medicine shows that people and institutions behave according to the ...
A metric ISO screw thread is designated by the letter M followed by the value of the nominal diameter D (the maximum thread diameter) and the pitch P, both expressed in millimetres and separated by a dash or sometimes the multiplication sign, × (e.g. M8-1.25 or M8×1.25). If the pitch is the normally used "coarse" pitch listed in ISO 261 or ...
