Solutions of a Quadratic Inverse Eigenvalue Problem for Damped Gyroscopic Second-Order Systems by Hong-Xiu Zhong, Guo-Liang Chen, Xiang-Yun Zhang

“…Given k pairs of complex numbers and vectors (closed under conjugation), we consider the inverse quadratic eigenvalue problem of constructing n×n real matrices M, D, G, and K, where M>0, K and D are symmetric, and G is skew-symmetric, so that the quadratic pencil Q(λ)=λ2M+λ(D+G)+K has the given k pairs as eigenpairs. …”

Two-dimensional DOA estimation of unitary transformation matrix reconstruction based on L-shaped array by Xiu WANG, Qing CHANG, Yaoli WANG

“…The estimation of the direction of arrival of two-dimensional space signals is the key problem in the field of array antennas.Although the traditional two-dimensional MUSIC algorithm has high precision,it needs two dimensional spectrum peak search and has a large amount of operation.A two-dimensional DOA estimation algorithm for L-shaped array was proposed.The output matrix was transformed from a complex value matrix to a real value matrix by matrix reconstruction and a unitary transformation matrix.This method could directly get the elevation angle of the target without conversion,which greatly reduced the amount of operation.Compared with the matrix enhancement and matrix pencil algorithm for L-shaped array,this algorithm could estimate more targets’DOA.The results of simulation show that the algorithm has a high accuracy of DOA estimation.…”

Hybrid Differential Evolution with Biogeography-Based Optimization for Design of a Reconfigurable Antenna Array with Discrete Phase Shifters by Xiangtao Li, Minghao Yin

“…The reconfigurable design problem is to find the element excitation that will result in a sector pattern main beam with low sidelobes with additional requirement that the same excitation amplitudes applied to the array with zero-phase should be in a high directivity, low sidelobe pencil-shaped main beam. In order to reduce the effect of mutual coupling between the antenna-array elements, the dynamic range ratio is minimized. …”

Images de l’étrange : Punch ou la re-présentation du paradigme bourgeois by Françoise Baillet

“…In the mid-Victorian period, at a time when the forces of respectability were rapidly transforming the British society, Punch, formerly famous for its biting pictorial comment on contemporary events, chose to champion the cause of the increasingly powerful middle-class. Under the pencil of Keene, Leech or du Maurier, the picture became one of the means through which the bourgeois identity was built, defended and promoted. …”
