Abstract: Coordinated air combat target assignment is a complex optimization problem based on situation evaluation. Traditional method seems to be inefficient and time consuming. To get rid of this disadvantage, Genetic Algorithm (GA) is introduced to solve this problem. GA is an efficient intelligent method for global optimization. The primary goal of this paper is to apply GA method to fulfil the aim of maximizing the coordinate effect. By designing proper fitness functions, GA is employed to air combat target assignment problem. Simulation results show that the GA method is more efficient than the traditional method.

Abstract: The proposal of the thesis of Scientific Outlook on Development and transforming Economic Development Pattern, as well as the need for social capacity improvement, which contributes to promoting the industrial policy to the innovation policy. However, there have been many problems in the innovation polices which were used to enhance the social capacity since Reforming and Opening in China, so, this paper puts forward the possible paths choices of Chinese innovation policy.

Abstract: A general decoupled control scheme based on the high-order active disturbance rejection controllers (HOADRCs) is proposed for the longitudinal dynamics of a generic hypersonic flight vehicle (GHFV). The longitudinal model of the GHFV is multivariable, high-order, highly nonlinear, tight coupling, highly unstable and includes uncertainties and disturbances. The feedback linearized model is decoupled into two independent channels. In each channel, the overall disturbance contains high-order derivatives and other complicated terms which are difficult to compute and therefore direct computing is not practical in real flight. Two HOADRCs are designed separately. Extended state observers (ESOs) are designed to estimate the overall disturbances. Moreover, high-order full-space aerodynamic coefficients are adopted. The nonlinear state error feedback (NLSEF) parameters are optimized using MATLAB simulink module. The simulation results demonstrate that the HOADRCs are highly effective and strongly robust for velocity and altitude control.

Abstract: This paper focuses on real option theory and its applications in 4G WiMAX mobile network. The objective of this paper are (1) to introduce real option theory and to discuss its applicability as a decision support tools, (2) to apply real option approach based on the proposed pricing model to the selected case to demonstrate the power of option pricing models. In this study, we intend to include the main investment costs of MNO in 4G WiMAX mobile network, which comprise of the costs of Base Transceiver Station (BTS), and Access Service Network Gateway (ASN-GW), in Network Access Providers (NAPs) domain for the cost analysis. After applying real options based on the proposed pricing model and the option’s parameters, the results show that the static Net Present Value (with option to expand) confirms the results obtained from the financial option (no option).

Abstract: The heterogeneous network-on-chip (NoC) has been proposed as a promising platform for future massive parallel computing. One major design concern on such platform is how to decrease the contention resulted from numerous concurrent communications on the NoC. Contention-aware task mapping is needed in order to alleviate the contention on the network and improve the system performance. In this work, we propose a tree-model task mapping algorithm which takes the bandwidth constraint on the communication channels into consideration. A new model is proposed in the algorithm in order to trade off the weighted communication volume and bandwidth requirement on the NoC. The quantitative comparison shows that the proposed contention-aware algorithm significantly reduces the bandwidth requirement and balances the work load on the communication channels, while the overhead of the weighted communication volume is minimized.

Abstract: Successful compensation system is a potential means that the enterprise gains and keeps competitive advantage. Many facts prove that the enterprise can't just let the market decide its salary strategy, and salary system must be designed from the strategy point of view. This paper expounds the connotation of the total compensation, and points out the relation between the compensation strategy and competitive advantage. The key whether the compensation strategy could enhances the competitive advantage of enterprises mainly depends on whether it would increase enterprise value or whether it is difficult to imitate; Then the disadvantage of traditional compensation strategy is also analyzed, and the following conclusion is drawn: in order to get and keep its competitive advantage the enterprise has to set up the total compensation strategy. Finally a model of enterprise competitive advantage based on the total rewards strategy is established to discuss how to develop salary strategy and how to set up the comprehensive and incentive compensation system in an enterprise in order to earn competitive advantage, which will provides theoretical support for implementing total compensation management of enterprise.
