A simile (/ ˈ s ɪ m əl i /) is a type of figure of speech that directly compares two things. [1] [2] Similes are often contrasted with metaphors, where similes necessarily compare two things using words such as "like", "as", while metaphors often create an implicit comparison (i.e. saying something "is" something else).
A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable (i.e. confounding variables). [1] This increases the reliability of the results, often through a comparison between control measurements and the other measurements.
Control charts are graphical plots used in production control to determine whether quality and manufacturing processes are being controlled under stable conditions. (ISO 7870-1) [1] The hourly status is arranged on the graph, and the occurrence of abnormalities is judged based on the presence of data that differs from the conventional trend or deviates from the control limit line.
Hierarchy of hazard control is a system used in industry to prioritize possible interventions to minimize or eliminate exposure to hazards. [a] It is a widely accepted system promoted by numerous safety organizations. This concept is taught to managers in industry, to be promoted as standard practice in the workplace.
where y is an n × 1 vector of observable state variables, u is a k × 1 vector of control variables, A t is the time t realization of the stochastic n × n state transition matrix, B t is the time t realization of the stochastic n × k matrix of control multipliers, and Q (n × n) and R (k × k) are known symmetric positive definite cost matrices.
A control variable (or scientific constant) in scientific experimentation is an experimental element which is constant (controlled) and unchanged throughout the course of the investigation. Control variables could strongly influence experimental results were they not held constant during the experiment in order to test the relative relationship ...
A number of literary works have commented negatively on the practice of comparison. For example, 15th-century English poet John Lydgate wrote "[o]dyous of olde been comparsionis", [15] which was reflected by many later writers, such as William Shakespeare, who included the line in Much Ado About Nothing, "comparisons are odious". [16]
The following table contains relatively general attributes of version-control software systems, including: Repository model, the relationship between copies of the source code repository Client–server , users access a master repository via a client ; typically, their local machines hold only a working copy of a project tree.
