Recently, several methods for single image super-resolution(SISR) based on deep neural networks have obtained high performance with regard to reconstruction accuracy and computational performance. This paper details the methodology and results of the New Trends in Image Restoration and Enhancement (NTIRE) challenge. The task of this challenge is to restore rich details (high frequencies) in a high...
This paper studies the distributed optimization problem for continuous-time multiagent systems with general linear dynamics. The objective is to cooperatively optimize a team performance function formed by a sum of convex local objective functions. Each agent utilizes only local interaction and the gradient of its own local objective function. To achieve the cooperative goal, a couple of fully distributed...
Power systems around the world are impacted by increasing penetration of Distributed Generations (DGs), which, in many cases, results in higher fault current levels. In some cases the increased fault current level may exceed the rating of the existing Circuit Breakers (CBs). Since fault current levels are, to a large extend, influenced by the network parameters and topology, which are not easily changed,...
The complex interactions between multistage manufacturing processes and different processing technologies is difficult to express with unified mathematical expression. In this paper, the reliability robust design model was studied based on directed topological graph. This model takes the quality characteristic variation loss in the manufacturing process as the objective function, with process sequence...
For the complex system subject to external detrimental factors and internal wear failures, both the proper protection and efficient maintenance activities on the system elements should be considered in order to maintain a desired level of system availability. A maintenance strategy consisting of preventive replacement and minimal repair is introduced, and the probability of destruction by external...
This paper proposes a dynamic partial reconstruction multicast routing algorithm (DPRA-MAODV), based on the analysis of MAODV agreement, combine with the dynamic partial reconstruction protocol. The creative use of the concept "event trigger", efficient implementation of partial reconstruction operation about the dynamic multicast tree in Ad hoc network, to optimize the total cost of the...
This paper considers the joint power allocation and subcarrier pairing problem in decode-and-forward (DF) relaying orthogonal-frequency-division multiplexing (OFDM) system, and proposes a strategy, called MW-RA, to maximize the weighted sum rate with total power constraint. MW-RA is formulated as a mixed integer programming problem and then transformed to a convex optimization problem by continuous...
This paper is concerned with the identification of multiple model process with transition using the output error (OE) method. Local multiple linear models with output error model structure are identified at fixed operating points first and then a global nonlinear model is approximated by interpolating the multiple linear models with exponential weighting functions. With all the obtained initial values...
This paper studies the control mechanism of a traffic network with multi-junction. In order to solve regional transportation problem with complex, strong stochastic features, more considerations focus on the mutual influence between junctions. Coordination control method based on multi-agent technology is proposed to process the coordination of district traffic when traffic jams occur, and a new specific...
