A Coherence Model Based on Syntactic Patterns

Annie Louis, Ani Nenkova
2012 Conference on Empirical Methods in Natural Language Processing  
We also show that our syntactic patterns are correlated with manual annotations of intentional structure for academic conference articles and can successfully predict the coherence of abstract, introduction  ...  Our work is based on the hypothesis that syntax provides a proxy for the communicative goal of a sentence and therefore the sequence of sentences in a coherent discourse should exhibit detectable structural  ...  So we expect that these articles form a good testbed for our models.  ...

Air quality impacts of plug-in hybrid electric vehicles in Texas: evaluating three battery charging scenarios

Tammy M Thompson, Carey W King, David T Allen, Michael E Webber
2011 Environmental Research Letters  
The air quality impacts of replacing approximately 20% of the gasoline-powered light duty vehicle miles traveled (VMT) with electric VMT by the year 2018 were examined for four major cities in Texas: Dallas  ...  A subset of electricity generating units (EGUs) in Texas that were found to contribute the majority of the electricity generation needed to charge PHEVs at the times of day associated with each scenario  ...  Acknowledgment The authors would like to thank the Texas Air Research Center for sponsoring this research.  ...

Nomadic migration: a new tool for dynamic grid computing

G. Lanfermann, G. Allen, T. Radke, E. Seidel
Proceedings 10th IEEE International Symposium on High Performance Distributed Computing  
The motivation for this migration framework, dubbed "The Worm", originated from the experience of having an abundance of computing time for simulations, which is distributed over multiple sites and split  ...  We describe the design and implementation of a technology which provides an application with the ability t o seek out and exploit remote computing resources by migrating tasks from site to site, dynamically  ...  WORM TECHNOLOGY IN A DYNAMIC GRID ENVIRONMENT Based on the early prototype experiences [9] a more scphisticated Worm framework was desgined t o provide the user with range of migration policies and t o  ...
