The data handled in emerging applications like location-based services, sensor monitoring systems, and data integration, are often inexact in nature. In this paper, we study the important problem of extracting frequent item sets from a large uncertain database, interpreted under the Possible World Semantics (PWS). This issue is technically challenging, since an uncertain database contains an exponential...
In many situations, telecommunication engineers are faced with the problem of extracting information from the network. This corresponds in many cases to infer on functionals of spectrum of random matrices with only a limited knowledge on the statistics of the matrix entries. Here, the inference on the spectrum of random matrices is realized by moments method. In its full generality, the problem requires...
In the digital VLSI cycle, logic transformations are often required to modify the design to meet different synthesis and optimization goals. Logic transformations on sequential circuits are hard to perform due to the vast underlying solution space. This paper proposes an SPFD-based sequential logic transformation methodology to tackle the problem with no sacrifice on performance. It first presents...
A time-to-market of mobile application software is usually very short and it causes unstructured mobile application software. In this paper, we defined a common architecture for mobile application software which is named as Application Framework to support agile software development. The framework is defined following PIM (Platform Independent Model) in MDD (Model Driven Development) to satisfy the...
We have been working to uncover gender differences in the ways males and females problem solve in end-user programming situations, and have discovered differences in males' versus females' use of several debugging features. Still, because this line of investigation is new, knowing exactly what to look for is difficult and important information could escape our notice. We therefore decided to bring...
