Physiographic Factors Defining The Snake River Valley Ava; Beyond "Vin De Idaho", David Wilkins, Virginia Gillerman, Krista Shellie, Ron Bitner, Gregory Jones Apr 2011

Physiographic Factors Defining The Snake River Valley Ava; Beyond "Vin De Idaho", David Wilkins, Virginia Gillerman, Krista Shellie, Ron Bitner, Gregory Jones

David E. Wilkins

Beginning in 1971 with the first plantings of wine grapes, the wine and wine grape industry in southwest Idaho have grown to become significant contributors to the state economy with an annual impact of $75 million (Bierle et al., 2008). With around 1600 acres under cultivation in 50 vineyards producing at least 24 varietals (as of 2007), wine grapes are the state's second largest fruit crop in acreage, with the majority of the crop (USDA, 2008) being produced in the western Snake River Plain of southwestern Idaho and eastern Oregon. In April, 2007, a 21,400 sq. km area in this …

Distribution Of Electron Traps In Cdse Nanocrystals Revealed By Multiple Population-Period Transient Spectroscopy (Muppets), Sean Kern, Kalyanasis Sahu, Mark Berg Feb 2011

Distribution Of Electron Traps In Cdse Nanocrystals Revealed By Multiple Population-Period Transient Spectroscopy (Muppets), Sean Kern, Kalyanasis Sahu, Mark Berg

Sean J. Kern

Electron traps on the surface of CdSe quantum dots cause nonradiative decay of single excitons, but the nature of the trap states is still poorly understood. Power-law (t-0.16) absorption recovery was found over the 0.7 ps-1.8 ns range, after correcting for biexciton formation. This nonexponential decay could be due to variation in the trapping rate from dot to dot (rate heterogeneity), relaxation in the exciton or trapped states, or cascading through multiple trap states (homogeneous mechanisms). MUPPETS is a 6th order, multidimensional spectroscopy that can distinguish heterogeneous mechanisms from homogeneous ones for nonexponential decays. Rate heterogeneity is found to dominate …


Bayesian Mixtures Of Autoregressive Models, Sally Wood, Ori Rosen, Robert Kohn Feb 2011

Bayesian Mixtures Of Autoregressive Models, Sally Wood, Ori Rosen, Robert Kohn

Sally Wood

In this paper we propose a class of time-domain models for analyzing possibly nonstationary time series. This class of models is formed as a mixture of time series models, whose mixing weights are a function of time. We consider specifically mixtures of autoregressive models with a common but unknown lag. The model parameters, including the number of mixture components, are estimated via Markov chain Monte Carlo methods. The methodology is illustrated with simulated and real data.

Loss Of Vision: How Mathematics Turned Blind While It Learned To See More Clearly, Bernd Buldt, Dirk Schlimm Feb 2011

Loss Of Vision: How Mathematics Turned Blind While It Learned To See More Clearly, Bernd Buldt, Dirk Schlimm

Bernd Buldt

To discuss the developments of mathematics that have to do with the introduction of new objects, we distinguish between ‘Aristotelian’ and ‘non-Aristotelian’ accounts of abstraction and mathematical ‘top-down’ and ‘bottom-up’ approaches. The development of mathematics from the 19th to the 20th century is then characterized as a move from a ‘bottom-up’ to a ‘top-down’ approach. Since the latter also leads to more abstract objects for which the Aristotelian account of abstraction is not well-suited, this development has also lead to a decrease of visualizations in mathematical practice.

Higgs-Boson-Exchange Models Of Cp Violation And K-]2pi, Jf Donoghue, Js Hagelin, Br Holstein Feb 2011

Higgs-Boson-Exchange Models Of Cp Violation And K-]2pi, Jf Donoghue, Js Hagelin, Br Holstein

Barry R Holstein

Work by Deshpande and Sanda, which appears to invalidate Higgs-boson-exchange models of CP noninvariance, is buttressed by (i) use of the MIT bag model to calculate matrix elements, (ii) use of experimental rather than calculated numbers for the K→2π decay amplitude and the KL-KS mass difference, and (iii) inclusion of possible t-quark effects. We conclude that, barring accidental cancellations, such Higgs-boson-exchange models are incompatible with experiment.

Weak Hypernuclear Decay, Br Holstein Feb 2011

Weak Hypernuclear Decay, Br Holstein

Barry R Holstein

Because of Pauli suppression effects the $N\pi$ decay of the free $\Lambda$ is not of importance in hypernuclei with $A\geq 10$. Rather the decay of such hypernuclei proceeds via the nucleon-stimulated mode $\Lambda N\rightarrow NN$, analysis of which presents a considerable theoretical challenge and about which there exists only a limited amount of experimental information. Herein we confront existing data wih various theoretical analyses which have been developed.

The Right Stuff: Are We Teaching It In College Algebra?, Lisa Yocco

Lisa S. Yocco

The Right Stuff: Appropriate Mathematics for all Students was an AMATYC project funded by the National Science foundation. The project promotes a redesigned college algebra course that engages students in data modeling, effectively uses technology, equips students with strong problem solving skills, increases critical thinking skills, and enhances quantitative literacy. Mathematics has traditionally been taught using “skill and drill” methods, which often leaves students bored, uninterested, and distasteful of math. An approach incorporating data analysis, modeling, and technology makes College Algebra relevant, refreshing, and interesting. As a result, faculty are preparing students mathematically for their majors, future careers, and life. …

Attempts have been made to extend SQL to work with multimedia databases. We are reserved on the representation ability of extended SQL to cope with the richness in content of multimedia data. In this paper we present an example of a multimedia database system, Computer Aided Facial Image Inference and Retrieval system (CAFIIR). The system stores and manages facial images and criminal records, providing necessary functions for crime identification. We would like to demonstrate some core techniques for multimedia database with CAFIIR system. Firstly, CAFIIR is a integrated system. Besides database management, there are image analysis, image composition, image aging, …

Content-Based Retrieval For Trademark Registration, Jian Kang Wu, Chiam Prong Lam, Babu M. Mehtre, Yunjun Gao, Arcot Desai Narasimhalu

Arcot Desai NARASIMHALU

With ever increasing number of registered trademarks, the task of trademark office is becoming increasingly difficult to ensure the uniqueness of all trademarks registered. Trademarks are complex patterns consisting of various image and text patterns, called device-mark and word-in-mark respectively. Due to the diversity and complexity of image patterns occurring in trademarks, due to multi-lingual word-in-mark, there is no very successful computerized operating trademark registration system. We have tackled key technical issues: multiple feature extraction methods to capture the shape, similarity of multi-lingual word-in-mark, matching device mark interpretation using fuzzy thesaurus, and fusion of multiple feature measures for conflict trademark …

This paper documents the ongoing implementation of the VILD visual language interface to the object-oriented multimedia database system, MDBMS. We set forth the infrastructure on which VILD has been developed, and describe in detail the three sections of the language system which have been completed: the Schema Editor to define the database, the Frame Editor to edit and enter data, and the Browser to view the data. We conclude with the query implementation of VILD.


A Framework For The Integration Of Expert Systems With Multimedia Technologies, Arcot Desai Narasimhalu Jan 2011

A Framework For The Integration Of Expert Systems With Multimedia Technologies, Arcot Desai Narasimhalu

Arcot Desai NARASIMHALU

Expert system (ES) technology allows the capture and replication of expertise in an application domain. So far, the type of data that is used by an expert system for its reasoning process remains primarily alphanumeric. Image, graphics, and other dynamic data such as voice and video are part of an emerging technology generally termed multimedia technology. This article highlights the critical issues in building a successful application combining the two technologies. Based on these critical issues, it also provides a framework for the integration of multimedia technology with expert systems technology.


Management Of Technology Deployed In Service Innovations, Arcot Desai Narasimhalu Jan 2011

Management Of Technology Deployed In Service Innovations, Arcot Desai Narasimhalu

Arcot Desai NARASIMHALU

Services form a major portion of the GDP of several nations, especially that of the first world nations. These nations also experience high cost of providing services of different kinds. This has resulted in the displacement of non-customer facing services to countries that can offer them at lower prices. Nations have to be concerned about sustaining their economies even as such off-shoring of services continue to grow. It is therefore important to understand how countries can create those service innovations that will help them retain the growth trajectory of their economies. We believe that the different types of service innovations …

The Future Of Innovation Is Bright And Shiny As Never Before, Arcot Desai Narasimhalu Jan 2011

The Future Of Innovation Is Bright And Shiny As Never Before, Arcot Desai Narasimhalu

Arcot Desai NARASIMHALU

This bright shiny future is due to several reasons including better understanding of opportunity identification and innovation management, significant advances in technologies, new economic realities and the shi ing focus to service innovation. Innovation was perceived as an art practised by an exclusive few sitting in an ivory tower of a corporate headquarters of a company. The availability of methods such as Disruptive Innovation, Blue Ocean Strategy and Innovation Rules has empowered ordinary individuals to identify innovation opportunities as never before. This is a sea change in the sheer number of minds searching for the innovation needles in other otherwise …

Colour Matching For Imaging Retrieval, Babu M. Mehtre, Mohan S. Kankanhalli, Arcot Desai Narasimhalu, Guo Chang Man

Arcot Desai NARASIMHALU

Color is an important attribute for image matching and retrieval. We present two new color matching methods, the Reference Color Table Method and a Distance Method, for image retrieval. Both these methods and an existing method Histogram Intersection were implemented and tested for a database size of 170 color images. To compare the efficacy of each method, a figure of merit, called Efficiency of Retrieval, is defined. The results show that both the new methods perform better than the existing method, and that the Reference Color Table Method gives the best results.

A Method For Monetizing Technology Innovations, Arcot Desai Narasimhalu Jan 2011

A Method For Monetizing Technology Innovations, Arcot Desai Narasimhalu

Arcot Desai NARASIMHALU

Technology innovations from most universities and research institutes are generally created with no clear path to commercialization in mind. This is largely due to the culture in academic institutions and research institutes whose mission it is to explore the creation of innovations that promise long term benefits. This culture of academic freedom leads to a stockpile of technology innovations at their technology transfer offices (TTOs). These offices are often in a dilemma on how best to monetize the technology innovations that are in their custody. While there have been many social science research methodology based studies on this subject under …

Fuzzy Content-Based Retrieval In Image Databases, Kang Wu Jian, Arcot Desai Narasimhalu Jan 2011

Fuzzy Content-Based Retrieval In Image Databases, Kang Wu Jian, Arcot Desai Narasimhalu

Arcot Desai NARASIMHALU

Image data are inherently visual. The description of visual characteristics of images are imprecise. Fuzzy retrieval of images stored in a feature-based image database is a natural means to access the data. Unfortunately, to the authors knowledge, little work has been done on fuzzy image database models and fuzzy retrieval of feature-based image databases. In this paper, a fuzzy image database model and a concept of fuzzy space are proposed and fuzzy query processing in fuzzy space and fuzzy indexing on complex fuzzy vectors are described. An example image database, the computer-aided facial image inference and retrieval system (CAFIIR), is …
