Effective Channel Coding for DCT Watermarks
We describe effective channel coding strategies which can be used in conjunction with linear programming optimization techniques for the embedding of robust perceptually adaptive ...

Biorthogonal matrix dirty paper coding for information hiding in still images
In this paper, a new method of dirty paper code design is investigated, namely the biorthogonal matrix. The error probability is analysed for the code design. Since the code has t...

Tailoring Word Alignments to Syntactic Machine Translation
Extracting tree transducer rules for syntactic MT systems can be hindered by word alignment errors that violate syntactic correspondences. We propose a novel model for unsupervise...

Adapting a WSJ-Trained Parser to Grammatically Noisy Text
We present a robust parser which is trained on a treebank of ungrammatical sentences. The treebank is created automatically by modifying Penn treebank sentences so that they conta...

Adaptive Time-Stepping for Incompressible Flow Part II: Navier--Stokes Equations
We outline a new class of robust and efficient methods for solving the Navier– Stokes equations. We describe a general solution strategy that has two basic building blocks: an im...
