This study compared conventional static fading, where the problem solving responsibility of the learner increases at a fixed sequence, with a novel adaptive fading design in which the learner assumes more problem solving responsibility only if her or his previous solution attempt is successful. This study was conducted in the engineering knowledge domain of introductory electrical circuit analy...

Chemical processes like carbonation of concrete structures are driven by slow diffusion processes and fast reactions. This leads to the formation of relatively sharp reaction fronts, which move slowly through the material. Self-adaptive finite element methods provide a tool to automatically generate meshes locally fine enough to capture the reaction, while coarser meshes are sufficient in the b...

The technological developments in the design of an adaptive optical scanning acoustic microscope are described. Its two key elements include a multi-channel acoustic wavefront detector to detect the acoustic wavefront aberration and a highly adaptive acoustic source to correct for the effects of aberration. We present experimental images acquired with the instrument that indicate the degree of ...

This paper gives an overview of research in the area of adaptive structures. A general description of smart material systems is given. Particular focus is given to the following fields of application: semi-passive concepts, energy harvesting, semi-active concepts, active vibration control, and active structural acoustic control. The use of adaptive structures in structural health monitoring app...

Previous research has shown that survival-related processing of word lists enhances retention for that material. However, the claim that survival-related memories are more accurate has only been examined when true recall and recognition of neutral material has been measured. In the current experiments, we examined the adaptive memory superiority effect for different types of processing and mate...

Few facts in biology are more certain than offspring inheriting genetic material from their parents, but not all genes are acquired this way. A new report documents the horizontal transfer of a potentially adaptive gene between distantly related plants.
