Due to the scarcity of the licensed spectrum, Licensed-Assisted Access Long-Term Evolution (LAA- LTE) network can be deployed in unlicensed spectrum, which is currently occupied by different Wi-Fi systems. It is a very challenging problem to ensure fair coexistence between LAA-LTE and Wi-Fi networks, in terms of spectrum sharing and traffic management. To solve this problem, a Fair Downlink Traffic...
This paper analyzes the characteristics of flexible flow-shop scheduling problem, using a new coding method and an improved genetic algorithm to solve the problem. This paper solves the problem by using the genetic manipulation and elitism strategy. The experimental results have shown that the proposed algorithm is available and effective approach for the FJSP.
The problem of power battery state of charge estimation for hybrid vehicle directly affects the vehicle performance and driving distance. Considering there exists nonlinear relationship between the battery state of charge and the observable external characteristics, this paper presents a kind of algorithm which is based on the combination of genetic algorithm and back-propagation neural network namely...
Multi-segment Primary Permanent Magnet Linear Synchronous Motor (MP-PMLSM) drives is investigated in this study for vertical linear transportation applications such as a ropeless elevator. The optimization model of MP-PMLSM is established for various considerations of force ripple, driving force, weight and cost. Single primary unit length and the number of primary units are newly chosen as important...
Discontinuous primary permanent magnet linear synchronous motor (DPPMLSM) has many merits in long-stroke transportation, including vertical, horizontal, and slanted model system, however, detent force of DPMLSM is particularly troublesome requiring positioning accuracy specially at low speed region as well as of position control and is different from short primary type and short secondary type PMLSM...
