This paper presents seven experiments to determine the optimal size of a box for the input of handwriting characters on PDAs. The experiments involve consideration of boxes for different kinds of characters, different sizes and shapes (square and rectangular), the learning effect, and the age differences of users. The results are assessed in terms of high performance factors (e.g., high charact...

Encoded lookup tables used in white-box cryptography are known to be vulnerable to power analysis due to the imbalanced encoding. This means that the countermeasures against white-box attacks can not even defend against gray-box attacks. For this reason, those who want to defend against power analysis through the white-box cryptographic implementation need to find other ways. In this paper, we ...

Programs for embedded multimedia applications typically manipulate several large multi-dimensional arrays. The energy consumption per access increases with their size; the access to these large arrays is responsible for a substantial part of the power consumption. In this paper, an analysis is developed to compute a bounding box for the elements in the array that are simultaneously in use. The ...

Insulin therapy has been the best choice for the clinical management of diabetes mellitus. The current insulin therapy is via subcutaneous injection, which often fails to mimic the glucose homeostasis that occurs in normal individuals. Oral delivery is the most convenient administration route. However, insulin cannot be well absorbed orally because of its rapid enzymatic degradation in the gast...

The aim of this work theoretical study is to theoretically investigate a inorganic membrane assisted purifcation process of an H2-rich stream derived from a conventional methanol steam reforming stage. In particular, a black-box model for multicomponent gas mixture purifcation is dev...
