Upper bound of degrees of freedom in cognitive MIMO interference network with user cooperation by Shi-lei ZHU, Na-e ZHENG, Sheng WANG, Han-ying HU

“…In(K+1)-user cognitive MIMO interference network,conventional algorithms distinguish the interference of primary users and secondary users by aligning them to the different interference space,separately.Therefore,it leads to the loss of spatial degrees of freedom(DoF).From the perspective of multiplexing the interference space,a new upper bound of DoF and its necessary condition was deduced.Furthermore,to verify the rationality and validity of the new upper bound,a cooperative joint interference alignment algorithm,in which a joint interference alignment indicator was designed and proposed based on norm theory and Rayleigh-Ritz theorem.The effectiveness of the algorithm was analyzed.Theoretical analysis and simulation results show that the new upper bound of DoF breaks upper bound given in the existing papers,and it can be achieved by the proposed algorithm.…”

旋转叶片异步振动参数辨识方法及试验验证 by 王茜, 雷晓波

“…Based on the principle of blade tip timing（ BTT） and the vibration principle of one degree of freedom,the parameter identification algorithm of rotating blade asynchronous vibration is established by using all phase FFT（ apFFT） and least square method.The algorithm is verified by numerical simulation,and the test parameter and empirical value of the rationality for sensor layout are given.The tests of asynchronous vibration parameter identification were launched on a fan rotor,while high pressure nitrogen was used to shock the blades to produce single frequency absolute occupancy vibration.Results show that the method for asynchronous vibration identification could accurately identify blade vibration parameters,and the vibration frequencies of all blades obtained are exactly the same.Frequency identification accuracy is high with the maximum relative error of 1.12% using strain analysis frequency as a baseline.Results verify that the method of asynchronous vibration parameter identification is correct.…”

Optimal allocation model of logistics alliance resources based on willingness to participate by Mengrong LI, Huayu ZHU, Jin QI, Yanfei SUN

“…In order to reduce the costs and improve the efficiency during large-scale logistics tasks, logistics alliances are established by enterprises to achieve scale effects.The stability of the cooperative operation of the logistics alliances is mainly reflected in the enthusiasm of enterprises for participating in cooperation.Therefore, a resource optimal allocation model based on the willingness to participate was proposed, considering the impact of the participation willingness of alliance members on the resource allocation of the alliance.A sorting method with the optimal solution based on the regret theory was proposed to solve the model, and the method was verified based on the participation willingness index.The results show that the participation willingness distribution score of the sorting method based on the regret theory is 3.5 times higher than that of the traditional method.It can be seen that the proposed method can effectively improve the scientificity and rationality of resource allocation, and can contribute to consolidate the stability of the collaborative operation of the supply chain.…”
