Quantum annealing device has shown a great potential in solving discrete problems that are theoretically and empirically hard. Boolean Satisfiability (SAT) problem, determining if there is an assignment of variables that satisfies a given Boolean function, is the first proven NP-complete problem widely used in various domains. Here, we present a novel mapping of the SAT problem to the quadratic unconstrained...
Considering the problem that structure information can be easily lost when the edge and texture regions of image are denoised by the Non-Local Means (NL-Means) denoising algorithm, and a NL-Means image denoising algorithm based on edge detection is proposed in this paper. Firstly the edge detection in the noise image is got by using the improved Sobel operator, and then the detecting result is used...
Wormhole switching technology is widely used in High Performance Computer (HPC) systems. The delay estimation of wormhole switching is mainly focused on average packet delay. But in order to provide Quality of Service (QoS) guarantees, we should analyze the end-to-end delay bound of wormhole switching. Based on models of Credit Stall and Switch Allocation Stall, we use arrival curve to constrain the...
This paper discusses the problem in college students from Tibet, who major in computer science and technology. The paper is mainly based on the routine teaching in data structure and two hundred questionnaires and it proposes the solution corresponding to the problem.
We present a multi-sensors system adopted in an intelligent robotic hand that works in underwater environment. Four kinds of different sensors, force sensor, image sensor, ultrasonic sensor and hall sensor, are adopted in this system. Among them, information gained by force sensors formed a closed loop together with the control variables in the system, thus, the accuracy and stability of the whole...
