This paper considers error-correction for information in array design, i.e., two-dimensional design such as QR-codes. The error model is multi deletion/substitution/erasure errors. Code construction the errors and an application of code are provided. decoding technique uses error-locator deletion codes.

This study aims to address potential costs of using incorrect worked examples in teaching mathematics. While such practice has been shown to be effective in educational research, previous findings in the memory literature suggest that exposure to an incorrect solution may lead students to later believe that it is correct due to increased familiarity. We designed a two-session experiment with 1-...

This study was motivated by the observation of early head movements (EHMs) occasionally generated before gaze shifts. Human subjects were presented with a visual or auditory target, along with an accompanying stimulus of the other modality, that either appeared at the same location as the target (enhancer condition) or at the diametrically opposite location (distractor condition). Gaze shifts g...
