Development Of Ion Beam Nuclear Transmutation Doping (Ibntd) For Novel Electronics In Extreme Conditions, Michael G. Pravica, Noel A. Guardala, Jack L. Price

NSTec UNLV Symposium

Development of IBNTD for electronics under extreme conditions.

•We hope to create novel wide bandgap devices using Ion Beam Nuclear Transmutation Doping (IBNTD). These devices may be used as rugged high power switches, and high current/low noise amplifiers. Diamond in itself represents a “Holy Grail” for electrical applications due to its very high thermal conductivity and excellent electrical characteristics.
•We also hope to develop devices that can convert the enormous energy from high-energy nuclear particles (α2+,β-,β+, γparticles) into useful electricity and thus harness the enormous energy still contained in “spent” nuclear fuel. Developing these direct energy conversion (DEC) devices would …

Development Of Smart Pv Inverters For The Smart Grid, Yahia Baghzouz

NSTec UNLV Symposium

The Electric Grid has become more complex with recent technological developments. There are more alternative power sources and sensors added into the mix at every part of the grid. The Energy Meter has changed over the past several years as well. The older meters were checked only once a month with a meter reader, but the new "Smart" Meters are capable of reporting energy usage at fifteen minute intervals.

Framework For The Analysis Of Coordination In Crisis Response, Hemant Purohit, Andrew Hampton, Valerie L. Shalin, Amit P. Sheth, John M. Flach

Kno.e.sis Publications

Social Media play a critical role during crisis events, revealing a natural coordination dynamic. We propose a computational framework guided by social science principles to measure, analyze, and understand coordination among the different types of organizations and actors in crisis response. The analysis informs both the scientific account of cooperative behavior and the design of applications and protocols to support crisis management.

The Economics Of Cybersecurity: A National Dilemma, Allan A. Friedman

Brookings Scholar Lecture Series

Cybersecurity has dominated recent headlines, but policy makers and pundits alike still combine different risks, threats, and solutions. Crime, espionage, and international conflict represent different dangers to our society at the local and national level, and each has a set of bad actors with different incentives. Conflating these areas can lead to poorly framed solutions. Exploring the economics of cybersecurity offers a set of tools to understand these incentives, and the sometimes complex policy challenges that arise in dealing with digital risk.

Discovering Fine-Grained Sentiment In Suicide Notes, Wenbo Wang, Lu Chen, Ming Tan, Shaojun Wang, Amit P. Sheth

Kno.e.sis Publications

This paper presents our solution for the i2b2 sentiment classification challenge. Our hybrid system consists of machine learning and rule-based classifiers. For the machine learning classifier, we investigate a variety of lexical, syntactic and knowledge-based features, and show how much these features contribute to the performance of the classifier through experiments. For the rule-based classifier, we propose an algorithm to automatically extract effective syntactic and lexical patterns from training examples. The experimental results show that the rule-based classifier outperforms the baseline machine learning classifier using unigram features. By combining the machine learning classifier and the rule-based classifier, the hybrid system …

A Semantic Problem Solving Environment For Integrative Parasite Research: Identification Of Intervention Targets For Trypanosoma Cruzi, Priti Parikh, Todd Minning, Vinh Nguyen, Sarasi Lalithsena, Amir H. Asiaee, Satya S. Sahoo, Prashant Doshi, Rick L. Tarleton, Amit P. Sheth

Kno.e.sis Publications

Background: Research on the biology of parasites requires a sophisticated and integrated computational platform to query and analyze large volumes of data, representing both unpublished (internal) and public (external) data sources. Effective analysis of an integrated data resource using knowledge discovery tools would significantly aid biologists in conducting their research, for example, through identifying various intervention targets in parasites, and in deciding the future direction of ongoing as well as planned projects. A key challenge in achieving this objective is the heterogeneity between the internal lab data, usually stored as flat files, Excel spreadsheets or custom-built databases, and the external …

Cognitive Approaches For The Semantic Web, Dedre Gentner, Frank Van Harmelen, Pascal Hitzler, Krzysztof Janowicz, Kai-Uwe Kuhnberger

Computer Science and Engineering Faculty Publications

A major focus in the design of Semantic Web ontology languages used to be on finding a suitable balance between the expressivity of the language and the tractability of reasoning services defined over this language. This focus mirrors the original vision of a Web composed of machine readable and understandable data. Similarly to the classical Web a few years ago, the attention is recently shifting towards a user-centric vision of the Semantic Web. Essentially, the information stored on the Web is from and for humans. This new focus is not only reflected in the fast growing Linked Data Web but …

Chemical Composition Of 16th- To 18th-Century Glass Beads Excavated In Paris, Laure Dussubieux, Bernard Gratuze

BEADS: Journal of the Society of Bead Researchers

Dating from the 16th to 18th centuries, 63 glass artifacts (mostly beads) recovered from two sites in Paris, France, were investigated using chemical analysis in an attempt to determine their place of origin. The late-16th-century material from the Jardins du Carrousel consisted of small, monochrome drawn beads with a soda-lime composition. Attributed to the 17th and 18th centuries, the beads recovered at the adjacent site of the Cours Napoléon were more diverse in shape, color, and composition. Although provenance attribution was difficult due to a lack of comparative data, it was possible to identify an increasing variety of glass recipes …

A Wampum-Inlaid Musket From The 1690 Phips' Shipwreck, Charles Bradley, Karlis Karklins

BEADS: Journal of the Society of Bead Researchers

In August of 1690, a fleet of ships under the command of Sir William Phips set sail from Boston to attack Quebec City during the second year of King William's War. The campaign failed and, as the fleet retreated, a number of vessels were wrecked in the St. Lawrence during a violent storm. The remains of one of these was discovered by a diver in a cove at l'Anse aux Bouleaux, Quebec, in 1994. Believed to be the Elizabeth and Mary, the wreck yielded numerous artifacts, including a wide array of weaponry. Among the long arms was a musket whose …

Guide To The Description And Classification Of Glass Beads Found In The Americas, Karlis Karklins

BEADS: Journal of the Society of Bead Researchers

This guide provides information relevant to the description and classification of glass beads recovered from archaeological sites in North and South America and the Caribbean. It is partly based on and intended to be used with "A Classification System for Glass Beads for the Use of Field Archaeologists," by Kenneth and Martha Kidd. Material presented includes a critical evaluation of several bead classification schemes, an overview of bead manufacturing techniques, a descriptive listing of the various classes and types of beads that have been recorded to date, and an explication of the physical attributes of a bead, as well as …
