Performance of XFAST in the presence of code Doppler by TANG Xiao-mei, YONG Shao-wei, WANG Fei-xue

“…The probability of detection and false alarm in XFAST（extended replica folding acquisition search technique） were introduced in the condition of code Doppler and deterioration of noise caused by replica folding.The simulation re-sults show that the model is correct,the equal signal to noise error is less than 0.5dB.The research is the academic base of XFAST parameter optimization and performance.When the extended replica folding number equal to 1,the model can be used to analyse other acquisition algorithm.…”

Algorithm of NAF scalar multiplication on ECC against SPA by Min WANG, Zhen WU

“…Against the problem that non-adjacent form(NAF)scalar multiplication on Elliptic curve cryptography(ECC) were not well resist the simple power attack(SPA),the implementation of NAF scalar multiplication and the mechanism of SPA attack were analyzed.Then a new algorithm,named equal power NAF scalar multiplication was presented.It was verified that equal power NAF scalar multiplication was efficient countermeasure against SPA attack by experimental analysis on power traces of the smartcard collected from the power analysis platform.…”

Les prescrits d’égalité des chances : rhétoriques ou pas seulement ? by Corinne Monney

“…This article, in the field of Sociology of Organizations and Ergonomic Psychology, highlights, following the results of a doctoral research based on the inductive method of the anchored theory (Glaser et Strauss, 2010), three profiles of teacher trainers in their relationship to the more equal prescriptions. It questions the standards in teacher education and the possible rhetorical value of a current prescription calling for greater equality or even integration/inclusion. …”

An External Gear Pump with Axial Stepped-gear Structure and Without Additional Trapped-oil Relief-grooves by Wang Hao, Song Anran, Li Yulong

“…In order to solve the problems in the existing gear pump with another trapped oil buffer groove, an external gear pump with axial stepped-gear structure for realizing two different contact ratios is proposed; the trapped-oil load flow from the gear section with a contact ratio greater than 1 is balanced by the trapped-oil relief flow from the gear section with a contact ratio equal to 1, and the trapped-oil phenomenon will be fully alleviated; then the relief gap from the gear section with a contact ratio equal to 1 is calculated by 3D feature method, and the trapped-oil pressure formula is derived by making the trapped-oil load flow equal to the trapped-oil relief flow; finally, an example is demonstrated and validated by PumpLinx software. …”
