BACKGROUND The visual speech signal can provide sufficient information to support successful communication. However, individual differences in the ability to appreciate that information are large, and relatively little is known about their sources. PURPOSE Here a body of research is reviewed regarding the development of a theoretical framework in which to study speechreading and individual di...

Interoperability among structure domains is a rather new field of research. There are many different approaches which fit into it. This paper gives some examples of how users interact with different structures, a brief description of some interoperability related projects, and an outlook on our future work in this research area.

Cellular automata (CA) are particularly well suited for cryptographic application and there are several previous studies in this topic (Benkiniouar & Benmohamed, 2004; Gutowitz, 1995; Kari, 1992; Nandi et al., 1994; Oliveira et al., 2004; 2008; Seredynski et al., 2003; Tomassini & Perrenoud, 2000; Wuensche, 2008; Wolfram, 1986). Since CA rule is simple, local and discrete, it can be executed in...

This thesis investigates packaging effects on precision bandgap voltage references used in LTC switching regulators. Packaging stress causes a mean offset and room temperature distribution widening of the bandgap reference output voltage, as well as inconsistent temperature characteristics. Bandgap references with and without a proprietary stress-relief mechanism were compared to determine the ...

In order to use expressions as the basis of a specification language, we admit undefinedness, and introduce nondeterminism through the use of a choice operator. We extend expressiveness of the language by allowing choice from a set of values. Such a set could be infinite, giving unbounded non-determinism, or it could be empty, producing miracles. In this paper we treat the miraculous specificat...

This paper presents work-in-progress in assessing the usefulness of a layout complexity metric in evaluating the usability of different screen designs. The metric is based on the Shannon formula from communication theory. Initially the metric was applied to thirteen Windows applications where thirty subjects were asked to rank screens on the basis of “good” design. A significant negative correl...

Continues on page 26 One of the most frequently asked questions regarding phlebotomy is, why are the potassiums high? The answer involves a variety of factors, which can have a significant impact on the care of a patient. When an abnormally high value exists, it frequently sets off a train of investigations looking for such severe diseases as: renal failure; adrenocortical hypofunction; and dia...

While the IETF standardized IPv6 more than fifteen years ago, IPv4 is still the prevalent Internet protocol today. On June 8th, 2011, several large content and service providers coordinated a large-scale IPv6 test-run, by enabling support for IPv6 simultaneously: the World IPv6 Day. In this paper, we compare IPv6 activity before, during, and after the event. We examine traffic traces recorded a...
