Two dimensional non-separable adaptive directional lifting structure of discrete wavelet transform
In this paper, we propose a two dimensional (2D) non-separable adaptive directional lifting (ADL) structure of discrete wavelet transform (DWT) and its image coding application. C...

Modelling and Implementing Complex Systems with Timebands
—We describe how to use a timeband architecture to model real-time requirements. The architecture separates requirements that use different time units, producing a family of mode...

Beyond separation of duty: an algebra for specifying high-level security policies
A high-level security policy states an overall requirement for a sensitive task. One example of a high-level security policy is a separation of duty policy, which requires a sensi...

"Space Frames": Using space, color and animation in the visualization of complex graph systems
This study concerns the development of 3D interfaces that aid the navigation of large data structures through the usage of the HSV color space, and the ensuing “spatial framesâ€...

Constraint-based Model Transformation: Tracing the Preservation of Semantic Properties
Abstract— We present and evaluate a novel constraintbased model transformation approach that implements a preservation-centric view. The proposed framework comprises formal prese...
