Due to resource constraints, digital image transmissions are a significant challenge for image sensor based wireless sensor networks (WSN). In this paper, we propose a novel robust and energy-efficient scheme, called image component transmission (ICT) in WSN by providing various levels of reliability during image transmissions. Essential components such as the information for the positions of significant...
The carbon-nanotube (CNT) bundle is a potential candidate for deep-nanometer-interconnect applications due to its superior conductivity and current-carrying capabilities. A CNT bundle is generally a mixture of single-wall and multiwall CNTs (SWCNTs and MWCNTs) and has not been fully explored in previous studies. This letter introduces a diameter-dependent model to analyze the conductance of both SWCNTs...
Data may contain inconsistencies that violate integrity constraints, the consistent query answering problem attempts to find answers common for every possible repair. In this paper, we study how to handle the inconsistent XML document, which conforms to the DTD, while violates constraints. We consider three types of constraints, including functional dependencies, keys and foreign keys. We provide...
Incremental ETL processes are used for the incremental maintenance of data warehouses, which is generally designed by users with ETL tools. Using existing methods of incremental maintenance of materialized views for reference, we put forward an approach to generate an incremental ETL process automatically from the full ETL process in this paper. Existing researches are focused on the incremental maintenance...
