This paper investigates the operations of the wavelet tree based quantization and proposes a constrained wavelet tree quantization for image watermarking. The wavelet coefficients ...
Large object-oriented applications are structured over large number of packages. Packages are important but complex structural entities that may be difficult to understand since ...
We present the Stack Trace Analysis Tool (STAT) to aid in debugging extreme-scale applications. STAT can reduce problem exploration spaces from thousands of processes to a few by ...

Software systems need to change over time to cope with new requirements, and due to design decisions, the changes happen to crosscut the system’s structure. Understanding how ch...
The one-way function tree (OFT) scheme proposed by Balenson et. al is widely regarded as an efficient key management solution for multicast communication in large dynamic groups. ...
