Approximation techniques are widely used in structural reliability analysis to build computationally inexpensive surrogate models to replace expensive-to-run computer analysis codes. Recently, kriging models are frequently utilized to construct surrogate approximations; however, they may be inefficient for systems having with a large number of design variables. Therefore, a new method-cokriging, which...
With the explosion in the amount of semi-structured data users access and store, there is a need for complex search tools to retrieve often very heterogeneous data in a simple and efficient way. Existing tools usually index text content, allowing for some IR-style ranking on the textual part of the query, but only consider structure (e.g., file directory) and metadata (e.g., date, file type) as filtering...
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...
