Digital images are easy to copy, to reproduce, to edit and to process maliciously. For this reason watermarking has emerged as an important technology for protecting copyright of multimedia products. A watermark is a digital signal carrying information about the copyright owner that is (or at least should be) permanently embedded into a digital product, making it robust to any alteration (malic...

Software visualisation employs various representations of software to help programmers better understand program code. However, there are many technologies that can be used to deliver software visualisations. These different software visualisation media have varying capabilities, and determining which medium is best suited for a particular software visualisation application can be a complex tas...

With advances in wireless networking and Moore’s law driven advances in computing capabilities, collaborative systems are needed to explore the large volume of distributed resources and new styles of communication. To achieve the goal of collaborative service for users with heterogeneous devices, the system needs to consider not only the traditional design issues, but also the heterogeneity of ...

We study the e ects of communication in Bayesian games when the players are sequentially rational but some combinations of types have zero probability. Not all communication equilibria can be implemented as sequential equilibria. We de ne the set of strong sequential communication equilibria (SSCE) and characterize it. SSCE di ers from the concept of sequential communication equilibrium (SCE) d...

Southern California Edison (SCE) seeks to discover, evaluate, and adopt energy and information technologies to implement a smarter, more robust electricity infrastructure to deliver greater amounts of renewable generation, use electricity as a fuel for vehicles, enable consumers to become active participants in the energy supply chain, and ensure the continued reliability and vitality of our na...

For any simple voting game (SVG), we consider the question posed in the title from two different points of view as to what voting power means. We also distinguish between blocs imposed by annexation and those formed voluntarily, and present some general theoretical results concerning these notions. We illustrate our theoretical findings with examples using both toy SVGs and the Qualified Majori...
