Data assimilation is an important technique to improve simulation results by assimilating real time sensor data into a simulation model. A data assimilation framework based on Sequential Monte Carlo (SMC) methods for wildfire spread simulation has been developed in previous work. This paper provides systematic analysis and measurement to quantify the effectiveness and robustness of the develope...

A text understanding system with learning capabilities is presented. New concepts are acquired by incorporating two kinds of evidence { knowledge about linguistic constructions in which unknown lexical items occur and knowledge about structural patterns in ontologies such that new concept descriptions can be compared with prior knowledge. On the basis of the quality of evidence gathered this wa...

Proxy reconstructions suggest that peak global temperature during the past warm interval known as the Medieval Climate Anomaly (MCA, roughly 950–1250 AD) has been exceeded only during the most recent decades. To better understand the origin of this warm period, we use model simulations constrained by data assimilation establishing the spatial pattern of temperature changes that is most consiste...

We introduce a knowledge-based approach to the analysis of real-world natural language texts, which addresses the particular needs of dealing with new knowledge items. In order to incrementally expand the underlying conceptual knowledge base, we exploit two kinds of evidence from the text understanding process, viz. qualitative knowledge about linguistic constructions in natural language texts ...

We attempt to understand how external institutional forces affecting ERP assimilation within organizations need not impact all organizations uniformly but instead can be moderated by the enterprises’ knowledge-based capabilities. Building on an institutional model of ERP assimilation, we investigate the role of absorptive capacity (ACAP) in ERP assimilation. Specifically we examine how the ACAP...

Impact of GPS (Global Positioning System) data assimilation is assessed here using a high-resolution numerical weather prediction system at 2.5 km horizontal resolution. The Zenithal Tropospheric Delay (ZTD) GPS data from mesoscale networks are assimilated with the 3DVAR AROME data assimilation scheme. Data from more than 280 stations over the model domain have been assimilated during 15-day lo...

This paper advocates the main ideas of the interactive model of representation of Mark Bickhard and the assimilation/accommodation framework of Jean Piaget, through a rhythm recognition demonstration program. Although completely unsupervised, the program progressively learns to recognize more and more complex rhythms struck on the user’s keyboard. It does so without any recording of the input f...

This article argues that the fundamental typological distinction pertaining to reduplication is that between phonological duplication and morphological doubling (the Dual Theory of reduplication). Phonological duplication, which occurs for a phonological purpose such as providing an onset or nucleus for a syllable or filling in the featural content of an otherwise unspecified timing unit in the...

198 words) ERP assimilation involves both strategic levels and individual level. Focusing on either micro or a macro stance yields an incomplete understanding of behaviour occurring at either level. The main objective of this research is to bridge across different levels of analysis in understanding ERP assimilation. First built upon the existing experiences with ERP software application and pr...
