My start with ecological risk assessment at the regional scale began with the
evaluation of risks within the fjord of Port Valdez, Alaska. I initially thought that
the process was going to be very straightforward. The USEPA had produced a
framework document and there were published case studies.
This paper presents a method for extracting distinctive invariant features from
images that can be used to perform reliable matching between different views of
an object or scene. The features are invariant to image scale and rotation, and
are shown to provide robust matching across a a substantial range of affine distortion,
change in 3D viewpoint, addition of noise, and change in illumination.
The features are highly distinctive, in the sense that a single feature can be correctly
matched with high probability against a large database of features from
Aquatic scientists have always been intrigued with concepts of scale. This interest perhaps stems from
the nature of ßuid dynamics in oceans and lakes energy cascades from spatial scales of kilometers
down to viscous scales at centimeters or less. Turbulent processes affect not only an organisms perception
of, and response to, the physical environment, but also the interaction between species, both within and
across trophic levels.
Scale-up in Chemical Engineering covering the important task of the scale-up of processes from the laboratory to the production scale, this easily comprehensible and transparent book is divided into two sections. The second part presents the individual basic operations and covers the fields of mechanical, thermal, and chemical process engineering with respect to dimensional analysis and scale-up.
A reference for the scale modeler and aviation enthusiast. General and detail photographs and drawings, five-view drawings, technical data and facts on the actual aircraft, kit and product reviews for the scale modeler, reference listings.
Scale is a unifying concept that cuts across all natural and social sciences. At the
same time, scaling is a common challenge in both basic and applied research.
Accordingly, scale and scaling have become two of the most widely used buzzwords
in ecology today. Over the past two decades, more than a dozen books and many
more journal papers have been published on the problems of scale and scaling in
ecology and geophysical sciences. These publications, as reviewed in the chapters of
this book, have contributed significantly to our current understanding of scale issues.
An empirical study of scale economies in the Chinese Railway System Although results are not presented here, I have estimated several additional
specifications of the basic empirical test. The absence of a positive choice effect does not
seem to derive from the particular weighting of the data used hereone might prefer to
weight MSAs equally, or by the number of SAT-takers, rather than by their high-school-age
populationsnor from the inclusion in the sample of schools with too few SAT-takers to
permit accurate estimation of the school mean...
Pursuant to a request by the Department of Defense, the National
Research Council (NRC) convened a study committee under the
auspices of the Computer Science and Telecommunications Board
(CSTB) to assess the nature of the U.S. national investment in software
research and, in particular, to consider ways to enhance the knowledge and
human resource base needed to design, produce, and employ software-
intensive systems for tomorrow’s weapons and operations systems.
Scale-up in Chemical Engineering: The first part details the theoretical principles, introducing the subject for readers without a profound prior knowledge of mathematics. All this is illustrated by 20 real-world examples, while 25 exercises plus solutions new to this edition practice and monitor learning.
Studies assessing rating scales are very common in psychology and related ﬁelds, but are rare in NLP. In this paper we assess discrete and continuous scales used for measuring quality assessments of computergenerated language. We conducted six separate experiments designed to investigate the validity, reliability, stability, interchangeability and sensitivity of discrete vs. continuous scales. We show that continuous scales are viable for use in language evaluation, and offer distinct advantages over discrete scales. ...
Now when I think of drawing scale I don't really think of drawing 1 ,2 & 3 point perspectives. I think of blowing things up, to size that is. I never really was too big on drawing perspectives because mostly they involved drawing buildings and machines and such. The drawings just seem very mechanical. That's fine and it certainly has it place.
This paper presents an attempt at building a large scale distributed composite language model that simultaneously accounts for local word lexical information, mid-range sentence syntactic structure, and long-span document semantic content under a directed Markov random ﬁeld paradigm.
Cross-document coreference, the task of grouping all the mentions of each entity in a document collection, arises in information extraction and automated knowledge base construction. For large collections, it is clearly impractical to consider all possible groupings of mentions into distinct entities.
Broad-coverage semantic annotations for training statistical learners are only available for a handful of languages. Previous approaches to cross-lingual transfer of semantic annotations have addressed this problem with encouraging results on a small scale. In this paper, we scale up previous efforts by using an automatic approach to semantic annotation that does not rely on a semantic ontology for the target language.
Word processors or computers used in Japan employ Japanese input method through keyboard stroke combined with Kana (phonetic) character to Kanji (ideographic, Chinese) character conversion technology. The key factor of Kana-to-Kanji conversion technology is how to raise the accuracy of the conversion through the homophone processing, since we have so many homophonic Kanjis. In this paper, we report the results of our Kana-to-Kanji conversion experiments which embody the homophone processing based on large scale collocation data. ...
This practical guide offers a short course on scaling CouchDB to meet the capacity needs of your distributed application. Through a series of scenario-based examples, this book lets you explore several methods for creating a system that can accommodate growth and meet expected demand. In the process, you learn about several tools that can help you with replication, load balancing, clustering, and load testing and monitoring.
These results in Normative factor structure of the AAMR adaptive behavior scale school, second edition suggest that interpretation of the ABS-S:2 should focus on its two maJor conceptual components (personal independence and social behav- ior) rather than them five factors and 16 domains endorsed by its authors. Correspondingly, comparison of domain scores to identify adaptive strengths and weaknesses should be de-emphasized because variation in these scores is best explained by the two common factors rather than specific adaptive domains.
We present a simple semi-supervised relation extraction system with large-scale word clustering. We focus on systematically exploring the effectiveness of different cluster-based features. We also propose several statistical methods for selecting clusters at an appropriate level of granularity. When training on different sizes of data, our semi-supervised approach consistently outperformed a state-of-the-art supervised baseline system.
