Rate-distortion optimized image compression using wedgelets
Most wavelet-based image coders fail to model the joint coherent behavior of wavelet coefficients near edges. Wedgelets offer a convenient parameterization for the edges in an ima...

Worst-case Optimal Conjunctive Query Answering for an Expressive Description Logic without Inverses
Answering conjunctive queries (CQs) has been recognized as a key task for the usage of Description Logics (DLs) in a number of applications, and has thus been studied by many auth...

Time and Bit Optimal Broadcasting on Anonymous Unoriented Hypercubes
We consider broadcasting on asynchronous anonymous totally unoriented Nnode hypercubes. First we generalize a technique, introduced in 3 , for partial broadcasting and orientation...
