Electronic screens on laptop and tablet computers are being used for reading text, often while multitasking. Two experimental studies with college students explored the effect of medium and opportunities to multitask on reading (Study 1) and report writing (Study 2). In study 1, participants (N = 120) read an easy and difficult passage on paper, a laptop, or tablet, while either multitasking or...

In our previous work, we have demonstrated techniques to embed and extract extrinsic signatures from halftone images and text documents. Well developed embedding algorithms should increase the payload capacity while enhance the reliability of detection. In this study, we will develop a printer model that will be used to optimize the embedding algorithm for capacity and detection reliability. Th...

The technique of High Performance Thin Layer Chromatography was utilized to separate the components of magenta colour inkjet printer ink. An attempt has been done to develop a protocol to examine and opine on the issue of identification of printer from which a document was printed.

The market for colour printers based on electrophotographic systems is growing steadily. The sector exceeded 690,000 units in 2001 and is forecast to reach some 1.5 million units by 2005. The printer expected to be the main driving force behind this market expansion is the tandem type colour printer. The tandem colour printer has separate processes and recording systems for cyan, magenta, yello...

This document is one of a set of documents, which together describe all aspects of a new Internet Printing Protocol (IPP). IPP is an application level protocol that can be used for distributed printing using Internet tools and technologies. This document describes IPP from a high level view, defines a roadmap for the various documents that form the suite of IPP specifications, and gives backgro...
