Tweens' characterization of digital technologies
Computers & Education, 2012The tweens are a transitional age group undergoing deep physical and psychological transformations. Based on a thirteen-focus group research design involving 103 students, and applying a tweens-centered approach, the characteristics of SMS, IM, Internet, digital photos, electronic games, and email were analyzed.

Characterization of leakage power in CMOS technologies
1998 IEEE International Conference on Electronics, Circuits and Systems. Surfing the Waves of Science and Technology (Cat. No.98EX196), 2002A model to statistically characterize the leakage power of CMOS digital circuits is presented. Based on the subthreshold leakage characterization at transistor and cell level, the leakage power consumption of a standard cell circuit is obtained. Also, in order to estimate the leakage power variability for a fixed state, a model of variations due to ...

Technological Hazard Characterization
2017In the framework of Natech risk assessment, technological hazard refers to a potential for the occurrence of adverse effects due to the release of hazardous substances, from process or storage equipment, caused by natural-hazard impacts. It is important to identify the equipment that acts as a hazard source, and to rank the hazard in terms of the type ...

Susceptibility characterization of microprocessor and LSI technology
Microprocessors and Microsystems, 1988Abstract Microprocessor and digital LSI technology used for process control in heavy industrial plant is subject to interference from electromagnetic (EM) radiation in the vicinity of these sites. This paper considers the tests that are necessary to demonstrate with some level of confidence that such equipment will not malfunction in the EM ...

Technology and characterization of Nd:YAG ceramics
AIP Conference Proceedings, 2010The Nd:YAG ceramics of 1% and 2% Nd dopant were produced by a solid‐state reaction of high‐purity (4N) nanometric oxides powders, i.e., Al2O3, Y2O3, and Nd2O3. Mean grain sizes of about 20 μm and grain boundaries less than 5 nm of Nd:YAG ceramic samples were evaluated in SEM and TEM measurements.

The characterization of technological zinc cycles
Resources, Conservation and Recycling, 2003A comprehensive accounting of the anthropogenic mobilization of zinc must treat a series of life stages: mining and processing, fabrication, utilization, and end of life. Reservoirs in which zinc resides include the lithosphere, ore and ingot processing facilities, at least a dozen major uses, several intentional and default stockpiles, landfills, and ...

P3GA: An Algorithm for Technology Characterization
Journal of Mechanical Design, 2015It is important for engineers to understand the capabilities and limitations of the technologies they consider for use in their systems. However, communicating this information can be a challenge. Mathematical characterizations of technical capabilities are of interest as a means to reduce ambiguity in communication and to increase opportunities to ...

On the Characterization and Measure of Machine Cells in Group Technology
Operations Research, 1996Group technology plays an important role in the design of an automated manufacturing system. The ideal situation is to partition the machines into machine cells and the parts into part families so that each machine cell together with the part family for the cell is independent of the rest of the system.

Characterization of outgassing for EUV technology
SPIE Proceedings, 2004Outgassing of photoresists needs to be minimized to avoid contamination of optics. A new challenge for EUV photoresists - that was not encountered for previous lithography technologies - is that exposures will occur in a vacuum environment. In order to design resists that meet the outgassing requirements for EUV lithography, current EUV photoresists ...

Active Nano-Characterization and Technology
Nanotechnology, 2004Recent strong demands to fabricate novel nanoscopic devices and functional materials have led to the development of new multi-functional tools for nanofabrication and nano-characterization with unconventional environments. Conventional analytical tools need to be totally updated to match the new technological trend of nanotechnology and nanoscience ...
