The effect of printer resolution and grayscale upon text print quality was evaluated both empirically and analytically. Empirical data on subjective print quality was obtained in two ways. First, people were asked to rate print quality on a scale of 1 to 10 where 10 was considered to be optimal. Second, people were presented with pairwise presentations of different print samples and asked to in...

Banding is one of the image artifacts for electrophotographic (EP) printers. Due to its origin within the EP process, it can also be viewed as an intrinsic signature of the specific printer. Modulating the EP process to generate banding signals that are below the human visual threshold but can be detected by effective detection approach can further extend the signature capacity. This deliberate...

As I write this sentence, I am glancing over at the color printer sitting beside my screen. In the popular jargon of the computer industry, that printer is called a "peripheral"—which, upon reflection, is a rather odd way to describe it. What, precisely, is it peripheral to? If the ultimate goal of my activity is to produce a physical artifact, then one would have to conclude that the printer i...

1 1. Command name and code: 2 RCTE 7 2a 2. Command meanings: 3 IAC WILL RCTE 3a The sender of this command REQUESTS or AGREES to use the RCTE option, and will send instructions for controlling the other side’s terminal printer. 3a1 IAC WON’T RCTE 3b The sender of this option REFUSES to send instructions for controlling the other side’s terminal printer. 3b1 IAC DO RCTE 3c The sender REQUEST or ...

Tool builders dealing with many different languages, and language designers require sophisticated pretty-print techniques to minimize the time needed for constructing and adapting pretty-printers. We combined new and existing pretty-print techniques in a generic pretty-printer that satisfies modern pretty-print requirements. Its features include language independence, customization, and increme...

When implementing a programming language, we often write a parser and a pretty-printer. However, manually writing both programs is not only tedious but also error-prone; it may happen that a prettyprinted result is not correctly parsed. In this paper, we propose FliPpr, which is a program transformation system that uses program inversion to produce a CFG parser from a pretty-printer. This novel...

We propose a method for the colorimetric characterization of a printer which can also be applied to any other type of digital image reproduction device. The method is based on a computational geometry approach. It uses a 3D triangulation technique to build a tetrahedral partition of the printer color gamut volume and it generates a surrounding structure enclosing the definition domain. The char...

Abstract Background Medial open-wedge high tibial osteotomy (HTO) is an effective and safe treatment method for medial osteoarthritis of the knee. However, unintended changes in posterior slope (PTS) may occur. Several factors cause PTS alterations after HTO; however, research on sagittal-plane inclination (SPOI) relation to sparse. The purpose this study was evaluate whether SPOI affects HTO. ...
