Time-of-Flight depth cameras provide a direct way to acquire range images, using the phase delay of the incoming reflected signal with respect to the emitted signal. These cameras, however, have a challenging problem called range folding, which occurs due to the modular error in phase delay-ranges are modulo the maximum range. To our best knowledge, we exploit the first approach to estimate the number...
To support the global reach concept, the hypersonic vehicle is designed to realize the global strike mission. The paper applies the enhancing parametrization method to the reentry trajectory optimization of the hypersonic vehicle. This problem is considered as an optimal control problem with some path constraints, which must be satisfied along the reentry phase. The purpose is to design an optimal...
Handover is the core procedure for assuring mobility of the users in any mobile network and its success rate is a key indicator of user satisfaction. In the current mobile networks, handover optimisation is done manually on a long timescale. In this paper, we introduce inter-NodeB coordination system and the parameters of user behavior and history data to optimise handover. First, we collect the data...
In this paper the game-theoretical is introduced into the multi-user power allocation in cooperative communication networks. We firstly divide the users into two groups that are users of real-time service and non-real-time service. We analyze the optimal power allocation for multi-service transmission; demonstrate the relationship between the two types of services. Then a bilevel programming model...
The optimized solution for cooling tower load is performed by the method of traversal of stagnation point. And the comparison between fitting results and measured results is done. The results show that the method of traversal of stagnation point can be used for the optimized solution of index formula, and the maximum relative error is -12.1%.
The economizer is a critical component in coal fired power stations. An optimal renewal strategy is needed for minimizing the lifetime cost of this component. Here we present an effective optimization approach which considers economizer tubing failure probabilities, repair and renewal costs, potential production losses, and fluctuations in electricity market prices.
On the basis of layer-built topology structure and one-to-many communication mode, a novel fault locating arithmetic based on comparison for multi-source network cluster nodes was presented to avoid fault node invalidation problem of wireless sensor networks. Mathematical model and the fault model were set up. Aiming at the locating model, the optimization process for the concentrative control of...
