Most of magnetic encoder ICs are on-axis, and they are generally suitable for inner rotor PMSM, sometimes used in external rotor PMSM. However, in some special occasions, these ICs are not used for the difficulty of mounting, for example, there is an external rotor PMSM with a hollow shaft, which is convenient for passing the control wire. It is difficult to mount these encoder ICs, because there...
Recently, the concept of Entropy of Primitive (EoP) has been proposed to measure the image visual information. Some successful EoP based application also be developed. In this paper, we further explore the concept of EoP and propose an improved version: the L1 norm based EoP. Our EoP takes full account of the properties of a dictionary's layered structure and the characteristic of a basis pursuit...
The Group-based Sparse Representation (GSR) is able to sparsely represent natural images in the domain of group, which enforces the intrinsic local sparsity and nonlocal self-similarity of images simultaneously in a unified framework. And the GSR-driven L0 minimization method for image restoration has been proposed. This paper expands the application of GSR from image restoration to low lighting image...
Wireless sensor networks are often deployed to work in harsh or disaster and other special environments, such as earthquakes, floods, fires, other outer space and the battlefield. Owing to the lack of energy or disaster scenarios, sensor nodes may fail easily. This severe reduce the data persistence in the network and the efficiency of the sensed data acquisition. Growth Codes (GC) can work effectively...
We report experimentally the chaos-assisted excitation of high-Q whispering-gallery modes in a deformed microcavity by a sub-wavelength fiber taper. This chaos-mediated coupling combines the advantages of fiber taper and free-space coupling.
Sparse matrix-vector multiplication (SpMV) is the most important computational kernel, since its widely application in the scientific and engineering fields. In this paper, a series optimization methods of SpMV for CSR format have been approached. We focus on the underlying, paralleling and working set, and implement the library named as Combine Optimized SpMV for CSR format (COSC) which is the first...
The civil servant performance appraisal is an appraisal of official quality and working result. It is an important measure which realizes systematized management. Through the analysis on some drawbacks in civil servant performance appraisal and based on the principle of fuzzy sets, in this paper, we adopt the methods of qualitative and quantitative, establish the model of fuzzy synthetic evaluation...
