This paper presents the structural design and optimization process of a morphing wing trailing edge (TE) flap. The flap consists of flexible upper and lower skins and various connections that constrains the relative motion between the upper and lower skins, and is actuated by an eccentric beam to which several discs of variable radii and setting angles with respect to the beam is rigidly attached...
In order to meet the explosive traffic demand, the capacity of Long Term Evolution(LTE) system needs to be further expanded, and one choice is to integrate unlicensed carrier into the overall LTE system. However, unlicensed band might be shared by other communication systems like Wi-Fi and radar, so the available bandwidth for each user could not be guaranteed. We propose a carrier aggregation resource...
Extended range electric vehicles (EREVs) provide the power required to drive the vehicle via power battery packs and an engine/generator unit. To make EREVs as efficient as possible, proper control strategy of its' drive train is essential. This paper proposes an improved thermostat/power tracking switching drive train control strategy, which control parameters are optimized by using genetic algorithm...
We propose to achieve scalable O-OFDM network planning with a genetic algorithm (GA) that operates in an adaptive way for high optimization efficiency. When the network topology and lightpath requests are given, the GA encodes the routing, spectrum and modulation assignments (RSMA) as genes and optimizes them iteratively. Both the crossover and mutation schemes in our proposed GA operate adaptively...
To extract polysaccharide of Camellia Cake, cellulase-assist method was used. The extraction conditions were: temperature 50°C; time 3h; adding amount of cellulase 0.35%. The extract rate of camellia cakes polysaccharide is 26.62%, The adequacy of this model was confirmed.
In view of shortcomings such as premature convergence and oscillation in Simple Genetic Algorithms (SGA), the article adopts the method of adaptive adjusting for the probabilities of crossover and mutation. So the Improved Genetic Algorithms (IGA) is formed by adding the transgenic operator to SGA. And the optimum design program of steel box-concrete composite arch bridge based on improved genetic...
