In order to solve the problem of shortage of workers in large hospitals, this study design a kind of short distance wireless communication system based on brain-computer-interface (BCI) technology, it chooses the ultra-low power MCU MSP430F5438 and nRF24L01 as the core, and it includes the design of Lab view platform, brain electrical simulator, nRF24L01 wireless transceiver system and voice prompts...
The prior distribution information of the factor is usually available, but it is ignored by the standard optimal design. For the sake of considering the distribution information of the factors in an optimal experimental design, the following works are done: Firstly, the least expected squares estimator (abbreviated as ELSE), which can consider the distribution information of the factors, is defined...
Meta-models are widely used to facilitate the analysis and optimization of engineering systems that involve computationally expensive simulations. Kriging is widely used as a meta-modeling technique to build surrogate models. However, the assumption of a stationary covariance structure underlying Kriging does not hold in situations where the level of smoothness of a response varies significantly....
As the autonomous underwater vehicle (AUV) are considered for a wider variety of military and commercial application. Effective obstacle avoidance schemes are essential to the success missions, especially in offshore environment. Response time to a threat or incident for coastline security is an area needing improvement. Classical mapping and obstacle avoidance algorithm are too complex to be applied...
This paper presents the development and implementation of a scheduling method that enables the BSA Autonomous Underwater Vehicle (AUV) to perform a mission operation while managing various resources autonomously. The mission is to survey several local areas in a dynamic ocean environment with different survey sensors. When a mission begins, it is assumed that during the execution of the mission, there...
Distribution reduction of an inconsistent information system is a reduction after that the credibility of rules obtaining from information systems remains unchanged. The paper analyzes various situations may be encountered when incremental data add to an inconsistent information system, then provides various methods to incrementally update discernibility formula, in most cases, incremental updating...
This paper presents an intelligent decision algorithm and an on-board architecture designed to enable an autonomous underwater vehicle (AUV) to carry out a survey mission autonomously. The connotation of global model in decision algorithm is analyzed, including environment information, mission information and Self-states of AUV. The survey mission of multi-objective operation areas in an unsafe zone...
The common method to solve performance bottleneck problems of network service nodes is to take use of server cluster systems. At present, the schema which uses centralized load balancer to do management of system load is dominant. But the load balancer used may become a bottleneck of the system. This paper first analyzes and compares the existing load balancing technologies, and then proposes the...
