The traditional linear quadratic control can be solved elegantly via the classical algebraic Riccati equation. Unfortunately, this Riccati approach is rather limitation to handle the indefinite linear quadratic control, since the inverse(generalized inverse) of indefinite matrix is hard to express. The semidefinite programming(or linear matrix inequality) based approach could tackle indefinite linear...
For two dimensional (2D) chemical images by light-addressable potentiometric sensor (LAPS), high photocurrent obtained in high ac frequency is the most critical criterion to have an acceptable signal-to-noise ratio in a very short time for a pixel. A simple KOH etch can be used to decrease the thickness of silicon substrate for high photocurrent. In the meantime, higher surface roughness in both sides...
Inventory control is to find a optimal strategy to minimum the cost or maximum the profit. There have been numerous research on inventory control with the linear or other convex objective functions. However, the nonconvex cases are the more frequently occurring in practice, which are more difficult to handle than the convex one. In this paper, a class of inventory control with nonconvex quadratic...
This paper studies a two-stage inventory problem arising from cold rolling production process in the steel industry. The problem is to find a optimal inventory level which satisfies the order demand and ensures the continuity of production via controlling the production rate.. Consider ring “transport of batch” to different sales center, we assume that the realization of the demand depends on the...
Depth-image-based rendering (DIBR) has attracted more and more attention as a method of virtual view rendering in three-dimensional video (3DV) applications. Many efforts have been dedicated to realize high-quality rendering, ranging from pre-process of the reference depth images to post-process of the virtual texture images. A DIBR method based on inverse mapping and depth-aided image inpainting...
It is currently a global hotspot that the application of multimedia and network technology to education is coming to be. There are inevitably threats brought about by the reliance on network and security problems of different levels in the modern web-based distance education system. This paper gives introduction to and analysis on the building of network security mechanisms in detail for distance...
