Three-level and mixed-level orthogonal arrays for lean designs
Orthogonal arrays (OA’s) are widely used in design of experiments. Each OA has a specific number of rows that is fixed by the number of factors in the OA and the number of leve...

Crease Surfaces: From Theory to Extraction and Application to Diffusion Tensor MRI
—Crease surfaces are two-dimensional manifolds along which a scalar field assumes a local maximum (ridge) or a local minimum (valley) in a constrained space. Unlike isosurfaces, ...

Reducing stack with intra-task threshold priorities in real-time systems
In the design of hard real-time systems, the feasibility of the task set is one of the primary concerns. However, in embedded systems with scarce resources, optimizing resource us...
