There is few researches focus on investigating game player's experience and preference between the young and elderly. In this study, four different braining training games designed by us are used to investigate the effects of age and game preference. In total, 136 participants were randomly selected, and they are separated into two age groups-young (N=90) and old (N=46). The experimental results demonstrate differential age effects in braining training games performance. Our results show that no matter what types of games young adults get better performance than the older adults and they all reach a significant difference. Meanwhile, due to the interface design may affect the willingness of older adults to play the game. Therefore, the usability is also studied by the design of game's control keys in a car racing game. The experimental results show that, older people respond relatively more slowly than the young people. Therefore, simpler interface design of brain training game is more suitable for older adults. In addition, the survey results indicated that the fruit catching game is loved by most of old people (reached 41.2%). The main reasons are without problem-solving stress and easy to play-player only need to control the right and left arrow keys. In other words, no psychological burden and simple interface design are the key factors in design popular games for elderly. However, young group is more like car racing game than others (28.6%). Since it is a playable game and they get a feeling of satisfaction when they reach a lower lap time. Finally, the brain age reference diagrams for the four developed games are proposed. Players can use these diagrams to understand their capability with respect to young and old group.

This paper proposes a nonlinear controller that allows the unmanned air vehicle (UAV) to follow a predefined path. The controller only needs the information of the inertial speed of the UAV and the distance between the vehicle and the desired path. In order to improve the performance of the controller, a parameter of the controller is optimized by using the concept of model predictive control (MPC). Lyapunov stability arguments are used to demonstrate that the path following error will be regulated to zero, even in the presence of wind disturbances. Simulation results in Matlab are given to show the effectiveness of the controller. The simulation results show that the proposed path following controller with parameter optimized by MPC (PLC_MPC) which takes the advantages of the predictive ability of the MPC and the simple structure of the normal path following controller (PLC) has better path following performance than that by using the PLC method.

The objective of this paper is to use the age-layered population structure model to increase diversity and control bloat of the population in linear genetic programming. Firstly, we use two level tournament selection to increase the sub-population diversity in each layer, and then apply the new model to linear genetic programming to increase the sub-population and the entire population diversity. The age-layered population structure model segregates individuals into different age-layers by their age, so it limits the quantity of the old age and long length individuals. Besides, the model regularly introduces new randomly generated short individuals into the youngest layer to reduce the average length of the population. The experimental results show that the age-layered population structure model can increase diversity and control bloat of the population effectively.

The characteristic of poor information of short text often makes the effect of traditional keywords extraction not as good as expected. In this paper, we propose a graph-based ranking algorithm by exploiting Wikipedia as an external knowledge base for short text keywords extraction. To overcome the shortcoming of poor information of short text, we introduce the Wikipedia to enrich the short text. We regard each entry of Wikipedia as a concept, therefore the semantic information of each word can be represented by the distribution of Wikipedia's concept. And we measure the similarity between words by constructing the concept vector. Finally we construct keywords matrix and use TextRank for keywords extraction. The comparative experiments with traditional TextRank and baseline algorithm show that our method gets better precision, recall and F-measure value. It is shown that TextRank by exploiting Wikipedia is more suitable for short text keywords extraction.

This paper focuses on mesh-partitioning metrics in large-scale parallel computational fluid dynamics (CFD) simulations. Mesh partitioning has a significant influence on the efficiency of parallel preconditioned conjugated gradient (PCG) solving procedure, which is the most representative and time-consuming part in parallel CFD. As the efficiency of parallel PCG depends on load balancing, communication overhead and iterative convergence rate comprehensively, we present a detailed review of mesh-partitioning metrics on these three aspects respectively. Three typical large-scale CFD applications are built to numerically testify the validity of all those metrics.

The purpose of this paper is to present an analysis on the resonance frequency of comparison calibration of the piezoelectric accelerometer to guarantee the accuracy and reliability of the calibration results. The operation principle of the piezoelectric accelerometer is firstly introduced and the natural frequency is obtained. Then, the vibration model of the comparison calibration is established and the mounted resonance frequency of the calibrated sensitivity is derived. The entire resonance frequency is achieved which is based on the deduced general form of the relative motion of the comparison calibration. The mounted resonance frequency is close to the entire resonance frequency at low mounted stiffness and approaches to the natural frequency as the mounted stiffness increases. The experimental results demonstrate that the mounted resonance frequency increases with the mounted stiffness. For the sake of high frequency calibration, the mounted stiffness should be kept high enough and the stude with silicone grease mounted method is a good choice.

Based on the queuing theory, a coordination and disruption management model of service supply chain is established to reflect the customer batch arrive condition. Most of current service supply chain models only reflect the situation of non-customer batch arrive, service's product character, only relative to service provider's efforts, non-cooperation value. This model improves current ones by considering service cooperation values, customers stochastic and batch arriving situation, and much more reflects the characters of actual service supply chain. Based on that, the coordination and disruption management strategy under the conjunction of disturbance factors including service market scale, service price, service quality and customer waiting cost, customer quit cost are provided to deal with this situation. The analysis result shows that the service efforts also play an important role to operation and coordination of service supply chain. The service effort cost sharing combined with income sharing contract can be used to coordinate the disrupted service supply chain under certain condition.
