High dimensionality (having a large number of independent attributes) is a major problem for bioinformatics datasets such as gene microarray datasets. Feature selection algorithms are necessary to remove the irrelevant (not useful) and redundant (contain duplicate information) features. One approach to handle this problem is wrapper-based subset evaluation, which builds classification models on...

Test access mechanisms (TAMs) and test wrappers are integral parts of a system-on-chip (SOC) test architecture. Prior research has concentrated on only one aspect of the TAM/wrapper design problem at a time, i.e., either optimizing the TAMs for a set of pre-designed wrappers, or optimizing the wrapper for a given TAM width. In this paper, we address a more general problem, that of carrying out ...

We propose two basic wrapper designs and an enhanced wrapper design for arbitrary digital hardware circuit designs such that they can be enhanced with the capability for dynamic swapping controlled by software. A hardware design with either of the proposed wrappers can thus be swapped out of the partially reconfigurable logic at runtime in some intermediate state of computation and then swapped...

“Accessing information anytime, anywhere, with any device” is a widely used slogan. The problem, however, is how to bring multimedia services to terminals with limited capabilities. Our approach offers a solution for delivering multimedia presentations to terminals connected to mobile or fixed networks with varying capabilities. Our media wrapper is used to adapt the original presentation accor...

Recent patents and progress on scan chain balance algorithms have been reviewed. With a significant increase of the SoC (System on Chip) integration and scale, the test time of SoC increase dramatically, and this makes the test cost of SoC grow rapidly. In order to reduce test cost and expense, the paper proposes an OBBO (Opposition-based learning and Biogeography Based Optimization) algorithm ...

The paper investigates techniques for extracting data from HTML sites through the use of automatically generated wrappers. To automate the wrapper generation and the data extraction process, the paper develops a novel technique to compare HTML pages and generate a wrapper based on their similarities and differences. Experimental results on real-life data-intensive Web sites confirm the feasibil...

We present a novel approach to automatic information extraction from Deep Web Life Science databases using wrapper induction. Traditional wrapper induction techniques focus on learning wrappers based on examples from one class of Web pages, i.e. from Web pages that are all similar in structure and content. Thereby, traditional wrapper induction targets the understanding of Web pages generated f...

We support exible query processing with autonomous networked information sources. Flexibility allows a query to be accepted in a dynamic environment with unavailable sources. Flexibility provides the ability to identify equivalent sources, based on their contents; these equivalences are used to eliminate redundancy and provide alternate query plans, when some source is unavailable. We determine...

The worker/wrapper transformation is a general way of changing the type of a recursive definition, usually applied with an eye to increasing algorithmic efficiency. This note identifies an infelicity in the program transformations presented by Gill and Hutton (2009) and proposes a new totally correct worker/wrapper fusion rule.

LAIO provided a wrapper mechanism that transformed synchronous system calls to asynchronous ones. This kind of wrapping could be useful for synchronous functions in user-space. This project explored relative topic by implementing LAIO with coroutines like a wrapper for the synchronous APIs on FreeBSD. After that, a simple evaluation is provided.
