In recent years, determining bearing capacity of piles from in-situ testing data as a complement to static and dynamic analysis has been used by geotechnical engineers. In this paper, different approaches for estimating bearing capacity of piles from SPT data are studied and compared. A new method based on N value from SPT is presented. Data averaging, &#10failure zone and plunging failure of p...

UNLABELLED Type IV pili (Tfp) are expressed by many Gram-negative bacteria to promote aggregation, adhesion, internalization, twitching motility, or natural transformation. Tfp of Neisseria meningitidis, the causative agent of cerebrospinal meningitis, are involved in the colonization of human nasopharynx. After invasion of the bloodstream, Tfp allow adhesion of N. meningitidis to human endothe...

The PilE pilin subunit protein of the gonococcal Type IV pilus (Tfp) colonization factor undergoes multisite, covalent modification with the zwitterionic phospho-form modification phosphoethanolamine (PE). In a mutant lacking the pilin-like PilV protein however, PilE is modified with a mixture of PE and phosphocholine (PC). Moreover, intrastrain variation of PilE PC modification levels have bee...

A method of damage identification of piles was established by using vibration characteristics. The approach focused on the application of the element strain energy and sensitive modals. A damage identification equation of piles was deduced using the structural vibration equation. The equation contained three major factors: change rate of element modal strain energy, damage factor of pile, and s...

With this opening sentence, Albert Spaulding introduced a now commonly used statistical procedure to archaeology called chi-square analysis. Spaulding was dissatisfied by typological procedures in common use at the time, and sought to make typology rigorous, replicable, and scientific. Most archaeologists at the time created archaeological types by putting artifacts together on a table, and the...

We define the Symmetric Ice Pile Model SIPMk(n), a generalization of the Ice Pile Model IPMk(n), and we show an efficient algorithm for generating the symmetric ice piles with n grains. More precisely, we show how to exploit an existing algorithm for generating IPMk(n) in order to generate SIPMk(n) in amortized time O(1) and in space O( √ kn).

The mechanism of pile-soil reaction in frozen ground is not clear at present, but it obvious that the reduction dead weight will be beneficial to seismic resistance bridges. In view limited bridge engineering practice high risk permafrost regions, paper addressed structural performance superstructure and its effect on piles these special regions. Four superstructures with different weights were...

We define three new take-away games, the Rat game, the Mouse game and the Fat Rat game. Three winning strategies are given for the Rat game and outlined for the Mouse and Fat Rat games. The efficiencies of the strategies are determined. Whereas the winning strategies of nontrivial take-away games are based on irrational numbers, our games are based on rational numbers. Another motivation stems ...

Nowadays, AC charging piles are widely used, and with the increasing number of piles, harmonic pollution generated by them becomes more serious affects power quality grid. Aiming at problem control single-phase pile, it is decided to apply active filter technology. The parallel (PAPF) selected according characteristics pile. single detection method studied based on instantaneous reactive theory...
