Algorithmic Blending

open access: yesJournal of Approximation Theory, 1993
An algorithm is given by wich one can obtain a 4-sided \(C^ 1\) surface patch. The algorithm can be used to interpolate 4 arbitrary polynomial boundary curves together with corresponding tangent planes. The method presented can be generalized to produce \(C^ K\) surfaces which are piecewise polynomial of degree \(2k+1\) or higher and which interpolate ...

Rheological and Physicochemical Characterization of Structured Chia Oil: A Novel Approach Using a Low-Content Shellac Wax/Beeswax Blend as Oleogelant

open access: yesGels
Vegetable oils structured with natural wax blends have attracted increasing interest due to their tunable crystallization and gelling behavior. This study evaluated the structuring of chia oil (ChO) using low concentrations (1–5%) of a shellac wax (SW ...

Blended learning spaces: Synchronous blending

open access: yesThe JALT CALL Journal, 2011
Discussions of blended learning (BL) have generally failed to account for the synchronous combination of computer-mediated and face-to-face interactions that can occur within a blended learning space (BLS). is paper provides an overview of BLS use by a department of teachers at a Japanese university specializing in foreign language learning.
