To set up a new evalution method in diagnosis of different carcinomas through positive index (PI), sum of direct positive index (SDPI) and sum of indirect positive index (SIPI). PI was defined as a ratio of resulting value (RV) to reference value (RF) in the article. Statistics was carried out to calculated test results of serum tumor markers. With its difference from sensitivity, specificity and...
The malfunction of the 100Hz protection in an HVDC system has severe effects on the safe and stable operation of the power system. In this paper, in combined with the improved converter switching-function model and the short circuit calculation of the ac system, a practical method to calculate the dc side 100 Hz current under ac faults is proposed. The computing efficiency is greatly improved by this...
For differential unitary space-time modulation (DUSTM), the bit-error performance is affected by the type of labeling. In this paper, we used the Binary Switching Algorithm (BSA) to optimize the labeling of cyclic constructed DUSTM constellation. Instead of time-consuming simulation, we constructed an easily-calculated cost function to estimate the impact of different types of labeling on the bit-error...
In recent years, multi-erasure correcting coding systems have become more pervasive. RAID6 is an important 2-erasure correcting code specification. But there is no consensus on the best concrete RAID6 coding scheme. Plank developed a brand new class of RAID6 codes called the Liberation codes that achieves good encoding, updating and decoding performance. In this paper, we present a chained decoding...
