In Electronic Travel Aids for the blind, accurately tracking a planned path is the foundation and premise of security guiding. To satisfy the requirement of accuracy and adaptability, a continuous closed-loop control method based on intelligent adaptive PID algorithm is proposed. The dynamic model of the walking guidance system is established, and the control law and the initial parameters of intelligent...
The weapon target assignment (WTA) problem is to find a proper assignment of weapons to the enemy's targets with the objective of minimizing the total expected survival value of the targets. The problem can be formulated as a nonlinear integer programming problem, and is proven to be NP-hard. In this paper, we focus on the case where the defense has multi-type weapons and the offense (the enemy) has...
The problem of recovering low-rank matrix from only a subset of observed entries is known as the matrix completion problem. Many problems arising in compressive sensing, image processing, machine learning, can be usefully cast as this problem. In this paper, we propose an extended linearized augmented Lagrangian method of multipliers for the problem, and prove its global convergence. We show that...
EMKC is an explicit congestion control algorithm which is designed for high bandwidth delay product (BDP) networks. Although delay-independence is an appealing characteristic, the EMKC system developed in exhibits undesirable equilibrium properties and slow fairness convergence behavior. To overcome these drawbacks, we propose a new method called AEMKC (Advanced Exponential Max-Min Kelly Control)...
To study the relative contribution of various suppression mechanisms of water mist, the interaction of water mist and pool fire in natural ventilation compartment is investigated by large eddy simulation (LES), mixture fraction combustion model and Euler-Lagrange method. Parametric studies are further performed to determine the effects of droplet diameter on water mist entrainment and fire suppression...
Dialect conversion is one of the most important aspects of Chinese speech synthesis. A Lanzhou dialect corpus has been built based on “word-list in dialectal survey” for the conversion of Lanzhou dialect from Mandarin. Speech corpus was recorded with contrastive (Lanzhou dialect vs. Mandarin) recordings. Five Degrees Tone Model based f0 models and statistical based duration and pause duration model...
Mobile users are often involved in team activities and exhibit collaborative mobility in realistic ad hoc network application scenarios. Due to diverse group mobility patterns, the network may remain partitioned for extended durations. This paper describes an approach to reduce the communication disruptions by deploying forwarding nodes. The forwarding nodes explore the field periodically in orderto...
Performance of a long -haul RZ-DPSK system is theoretically characterized. It is observed that number of dispersion blocks in the dispersion map combined with the SPM causes the performance degradation near the system zero dispersion wavelength.
