Dot matrix printers are a type of impact printer that prints using a fixed number of pins or wires [2] [3] and typically use a print head that moves back and forth or in an up-and-down motion on the page and prints by impact, striking an ink-soaked cloth ribbon against the paper. They were also known as serial dot matrix printers. [4]
Another third-party innovation was an add-on peripheral called the ThunderScan, which allowed the printer to work as a low-cost optical scanner (in which the scanner mechanism temporarily replaced the ink ribbon cartridge). The ImageWriter II also supported an optional motorized sheet feeder that could feed cut-sheet paper.
All trashlines on refiles and corrections must include the word 'corrects' or 'correcting'." [ 1 ] A correction differs from a clarification, which clears up a statement that – while factually correct – may result in a misunderstanding or an unfair assumption.
Thermal-transfer printing is done by melting wax within the print heads of a specialized printer. The thermal-transfer print process utilises three main components: a non-movable print head, a carbon ribbon (the ink) and a substrate to be printed, which would typically be paper, synthetics, card or textile materials.
When solving the minimization problems arising in the framework of bundle adjustment, the normal equations have a sparse block structure owing to the lack of interaction among parameters for different 3D points and cameras. This can be exploited to gain tremendous computational benefits by employing a sparse variant of the Levenberg–Marquardt ...
The canon of a work of fiction is "the body of works taking place in a particular fictional world that are widely considered to be official or authoritative; [especially] those created by the original author or developer of the world". [2] Canon is contrasted with, or used as the basis for, works of fan fiction and other derivative works. [3]

The problem is that in estimating the sample mean, the process has already made our estimate of the mean close to the value we sampled—identical, for n = 1. In the case of n = 1, the variance just cannot be estimated, because there is no variability in the sample. But consider n = 2. Suppose the sample were (0, 2).
