Microscopic urine analysis can help humans detect many problems and diseases in the body. Traditional microscopic urine analysis is time consuming and subjective, so computer-assisted automated microscopy can help overcome these problems. Urine crystallization can be used as an important criterion for the diagnosis of human kidney stones. This paper introduces an integrated method for the detection and identification of crystalline components in urine microscopic particles, in which crystalline particles, red blood cells, white blood cells, epithelial cells, and tubular cell samples are used in this experiment. Firstly, the canny operator is used to detect and locate the particles, and then use the MRF segmentation to extract the strong texture structure of the target object, so as to facilitate the extraction of subsequent recognition features. A new shape feature is proposed, the Sector statistical Fourier descriptor, combined with the corner feature and the circularity feature to form the feature vector for the SVM classifier. Compared with the Similar work, this paper simplifies the calculation with fewer features, improves the recognition speed, and the recognition accuracy is as high as 97.8%, and the recognition effect is stable.
A novel dynamic bandwidth allocation algorithm named GTH-DBA is proposed for metro networks. A testbed is
constructed to test its performance. Numeric results show that this algorithm is effective to improve the
bandwidth efficiency of the metro networks.
This paper introduces a dynamic bandwidth assignment algorithm designed for ring topology (R-DBA) in order to
meet the needs of the construction of Metropolitan Area Network (MAN).This algorithm targets ring topology,
based on fair iteration, supports various QoS services and has previous assignment mechanism.
The availability of reliable optical sensor technology provides opportunities to better characterize and control plasma
etching processes in real time, they could play a important role in endpoint detection, fault diagnostics and processes
feedback control and so on. The optical emission spectroscopy (OES) method becomes deficient in the case of deep
submicrometer gate etching. In the newly developed high density inductively coupled plasma (HD-ICP) etching system,
Interferometry endpoint (IEP) is introduced to get the EPD. The IEP fringe count algorithm is investigated to predict the
end point, and then its signal is used to control etching rate and to call end point with OES signal in over etching (OE)
processes step. The experiment results show that IEP together with OES provide extra process control margin for
advanced device with thinner gate oxide.
In this paper, the three ameliorated new coding schemes of the Super-FEC (Forward Error Correction) concatenatedcodes
(namely, the inner-outer concatenated-code, the parallel concatenated-code and the successive concatenated-code
with interleaving) are proposed after the development trend of high-rate optical transmission systems and the defects of
the FEC codes in the current optical transmission systems have been analyzed. The system simulation of the inner-outer
concatenated-codes is implemented and the schemes of encoding/decoding the parallel concatenated-codes are proposed.
Furthermore, the two successive concatenated-codes with interleaving of the RS(255,239)+RS(255,239) code and the
RS(255,239)+RS(255,223) code are simulated, and the analyses for the simulation results show that the two successive
concatenated-codes with interleaving, compared with the classic RS (255,239) code and other codes, are a superior code
type with the advantages of the better correction error, moderate redundancy and easy realization. And their net coding
gains (NCG) are respectively 1.5dB, 2.5dB more than that of the classic RS(255,239) code at the BER (Bit Error Rate) of
10<sup>-12</sup>. At last, based on the ITU-T G.709, the frame format of the new concatenated-code on applying in high-rate optical
transmission systems is proposed and designed, this lays a firm foundation in order to design its hardware in future and
pioneers a direction in its physical application.
