Virtual characters often have their motion defined by an animation database, as is typical in video games. We organize an animation database into a parametrized motion graph. Motion graphs structure animation databases: Nodes in the graph represent decision points, and edges represent feasible transitions between motions. Rose et al. [1998] and Heck and Gleicher [2007] extend this structure whe...

In many cases of heavy earthquakes, liquefaction has resulted in serious damages. Existing anisotropy in soil layers results  in some difficulties to realize the reason for these phenomena. Loose sand lenses buried in fine soils are one of the cases which may result in these problems and as a weak point during the earthquake can cause this phenomenon. In this paper, using FLAC 2D software, doub...

C olleagues in my research group and in collaborating institutions typically model software designs using graph-ical tools such as Rational Rose, Together, and Visio. I often witness them toiling to adjust a graph's appearance with the mouse or laboriously visiting each class to change a single field's type. This need not be so. Design models should be composed textually, and graphs should be a...

During the last ten years, many organizations have invested resources and energy in order to be rated at the highest level as possible according to some maturity models for software development. Since measures play an important role in these models, it is essential that CASE tools offer facilities to automatically measure the sizes of various documents produced using them. This paper introduces...

The revision history of a software system conveys important information about how and why the system evolved in time. The revision history can also tell us which parts of the system are coupled by common changes: “Whenever the database schema was changed, the sqlquery() method was altered, too.” This “evolutionary” coupling can be compared with the coupling as imposed by the system architecture...

Software watermarking involves embedding a unique identifier within a piece of software, to discourage software theft. The global revenue loss due to software piracy was estimated to be more than $50 billion in 2008. We survey the proposed software watermarking algorithms based on graph encoding. Graph based watermarking schemes, like other watermarking schemes, can be divided into two groups: ...
