Locally-Stable Macromodels of Integrated Digital Devices for Multimedia Applications

This paper addresses the development of accurate and efficient behavioral models of digital integrated circuits for the assessment of high-speed systems. Device models are based on suitable parametric expressions estimated from port transient responses and are effective at system level, where the quality of functional signals and the impact of supply noise need to be simulated. A potential limitation of some state-of-the-art modeling techniques resides in hidden instabilities manifesting themselves in the use of models, without being evident in the building phase of the same models. This contribution compares three recently-proposed model structures, and selects the local-linear state-space modeling technique as an optimal candidate for the signal integrity assessment of data links. In fact, this technique combines a simple verification of the local stability of models with a limited model size and an easy implementation in commercial simulation tools. An application of the proposed methodology to a real problem involving commercial devices and a data-link of a wireless device demonstrates the validity of this approac

Cohesive Devices Used in the Headline News of the Jakarta Post

The study deals with the types of cohesive devices used in Headline News of The Jakarta Post. The objectives of study are to identify and to derive the types of cohesive devices dominantly used in headline news of the Jakarta Post. The data are taken from headline column of The Jakarta Post from online edition. There are seven articles which are analyzed in this study. This research is conducted by using descriptive method. The findings show that there are 162 references, 4 substitutions, 34 Ellipsis, 349 conjunctions, and 36 lexical cohesion occur in this study. The most dominant type of cohesive devices is conjunction because the writer would like to connect ideas within the text to make its readers easy to understand. Then the writer would like to make their news more informative. Keyword : cohesion, cohesive device, The Jakarta Post

E-Pedagogy of Handheld Devices 2013 Survey: Patterns of student use for learning

The Pedagogy of Ebooks (E-Ped) project began in 2012 and seeks to document, analyse and explain the changing study practices of UK distance learning students as they employ, adapt and integrate the use of new portable digital devices such as e-book readers and tablets into their learning. This report describes the results of an undergraduate survey undertaken in 2013 at the Open University (UK) which asked students how they used e-readers, tablets and smartphones for study. This research represents a snapshot of the rapidly changing interaction between technology and education, and highlights issues and opportunities for Higher Education in supporting student adoption of appropriate technologies and development of effective new methods of study

Single Value Devices

We live in a world of continuous information overflow, but the quality of information and communication is suffering. Single value devices contribute to the information and communication quality by fo- cussing on one explicit, relevant piece of information. The information is decoupled from a computer and represented in an object, integrates into daily life. However, most existing single value devices come from conceptual experiments or art and exist only as prototypes. In order to get to mature products and to design meaningful, effective and work- ing objects, an integral perspective on the design choices is necessary. Our contribution is a critical exploration of the design space of single value devices. In a survey we give an overview of existing examples. The characterizing design criteria for single value devices are elaborated in a taxonomy. Finally, we discuss several design choices that are specifically important for moving from prototypes to commercializable products

Our Own Devices

A flickering glow welcomed me to my university’s chapel service. Votive candles? If only. No, these were glowing smartphones, as thick as fireflies on a summer’s evening. It was a scene of tremendous absurdity, like a man watching TV while making love to his wife: distracted people distracting themselves during a sacred act. It struck me as oddly understandable (I even joined them to check my email during the sermon), yet also as the foretaste of some looming spiritual crisis. So much has been written lately about the perils of smartphone use that I’m reluctant to join the chorus. Yet I feel that many Christians—I include myself—have yet to find any healthy forms of resistance to this new cultural habit
