Isolation and deposition of specific live cells with the high spatio-temporal resolution from the heterogeneous mixtures are of critical importance to a wide range of biomedical applications. In this paper, we report a robot-assisted cell manipulation tool with optical tweezers based on a uniquely designed microwell array. The whole automatic manipulation includes the target cell recognition, isolation,...
The matched filter, as a popular method, has been widely used to image a target in the radar society. Nevertheless, there exists an important difficulty that the resolution of the image produced by the filter can be changed with the variation of the target's distance. In this paper a distinct imaging algorithm through the exploitation of the sparsity of the received echoes is presented for the multiple-input...
The principle and realization process of fuzzy PID algorithm are discussed in this paper.Component object of the algorithm is created in Matlab,then the simulation of fuzzy PID controller is realized in C++ Builder through calling interface function of component object.
The back-projection (BP) algorithm is a popular imaging method. Nevertheless, there exists a difficulty that the cross-range resolution acquired by the standard BP algorithm is dependent on the bandwidth of transmitted signal when the BP algorithm is directly used to the multiple-input multiple-output (MIMO) radar for imaging a target in the cross-range direction without any variation. In this paper,...
To reduce the hardware complexity which is aroused by the limitation of sampling theory because of the use of the frequency-domain method, a wide-band MIMO imaging method based on a symmetrical exponential distribution nonlinear array is proposed. Compared to the uniform linear array, this given exponential distribution nonlinear array has the lower sidelobe level and better imaging performance. Furthermore,...
In this paper we propose an imaging method via wideband multiple-input multiple-output radar to reduce the hardware complexity of the system. Since a spatial parallel procedure to sample the scattered echoes during a single snapshot illumination, instead of the spatial sequential sampling procedure during multiple snapshot illuminations in classical ISAR imaging, is utilized in our method, the complex...
Aiming at the special space in the tunnel, this paper assumes the geometric distribution of scatterers which is totally different from on the ground, puts forward a new GBSB model of MIMO channel and deduces the space-time correlation function of the model. The results of theoretical analysis and simulation show that the model can more accurately reflect the factors which impact the channel correlation...
According to the features of sparse data source while mining association rules, the paper designs a special linked-list unit and two strategies to store data in matrix. A novel algorithm, called SMM (Sparse-Matrix Mining), is proposed to find large item sets from sparse matrix. SMM maps database into a binary sparse matrix and stores compressed data into a linked-list, from which to find large item...
