Near-Universal Cycles for Subsets Exist
, 2008
"... Let S be a cyclic n-ary sequence. We say that S is a universal cycle ((n,k)-Ucycle) for k-subsets of [n] if every such subset appears exactly once contiguously in S, and is a Ucycle packing if every such subset appears at most once. Few examples of Ucycles are known to exist, so the relaxation to pa ..."

Universal and Near-Universal Cycles of Set Partitions
"... We study universal cycles of the set P(n, k) of k-partitions of the set [n]:= {1, 2,..., n} and prove that the transition digraph associated with P(n, k) is Eule-rian. But this does not imply that universal cycles (or ucycles) exist, since vertices represent equivalence classes of partitions. We use ..."

Loopy belief propagation for approximate inference: An empirical study. In:
- Proceedings of Uncertainty in AI,
, 1999
"... Abstract Recently, researchers have demonstrated that "loopy belief propagation" -the use of Pearl's polytree algorithm in a Bayesian network with loops -can perform well in the context of error-correcting codes. The most dramatic instance of this is the near Shannon-limit performanc ..."

An Analysis of Idle CPU Cycles at University Computer Labs
"... Abstract. Grid computing has a great potential for grand challenge scientific problems such as Molecular Simulation, High Energy Physics and Genome Informatics. Exploiting under-utilized resources is crucial for a cost-effective, large-scale grid computing platform (i.e., computational grid), but th ..."

), but there has been little research work on how to predict what resources will be under-loaded in the near future. In this paper, we analyze idle CPU cycles of PCs at university computer labs and present techniques for predicting idle cycles to be efficiently scheduled for parallel/distributed computing. Our

"... dissemination of spoken language accelerate the demise of regional dialects and less widely spoken languages? Written contracts today have greater legal standing than verbal ones. Will that distinction persist in a world in which spoken and written words have equal perma-nence? How can we harness th ..."
An Innovative Learning Cycle in Problem-Based Learning
"... Abstract: University Tun Hussein Onn Malaysia (UTHM) has decided since 2005 to fully implement Problembased Learning (PBL) in teaching and learning. Since then, PBL has become the major teaching and learning approach among lecturers and students. However, some problems were reportedly faced by the ..."

2001: Mesoscale modeling of katabatic winds over Greenland and comparisons with AWS and aircraft data
- Meteor. Atmos. Phys
"... Verification of two months, April and May 1997, of 48-h mesoscale model simulations of the atmospheric state around Greenland are presented. The simulations are performed with a modified version of The Pennsylvania State University–National Center for Atmospheric Research fifth-generation Mesoscale ..."

Monthly mean values of the near-surface tem-perature and wind speed predicted by the Polar MM5 differ from the observations by less than 1 K and 1 m s21, respectively, at most sites considered. In addition, the model is able to simulate a realistic diurnal cycle for the surface variables, as well
Fuel-Cycle Fossil Energy Use and Greenhouse Gas Emissions of Corn Ethanol.” Paper presented at the 8 th Bio-Energy Conference
