This paper presents a numerical investigation on the improvement mechanism of dynamic compaction (DC) in saturated soil weak layer with high levels groundwater, using an improved fluid–solid coupling method Drucker–Prager–Cap model. The model is verified by comparing published test data at first, which show that dual-phase can approximately reflect development law excess pore water pressure and...

Because of the limitations inherent in conventional transmission electron microscopy (TEM) using epoxy ultrathin sections for a clear recognition of biological entities having electron densities similar to or lower than that of epoxy resin, embedment-free sectioning for TEM has been developed. Embedment-free section TEM is reliably performed using water-soluble polyethylene glycol (PEG) as a tr...

Sheet pile walls are flexible retaining structures that used to hold the horizontal soil pressures behind them, especially in situations cause stress changes such as excavation. They divided into two cantilever and externally supported. Cantilever excavations with a maximum depth of 6 meters supported by anchors deeper than this. Some values be calculated design sheet embedment bending moment t...

The thesis introduced the traits about embedded GIS Based on Reworks developed with domestic technologies . Embedded terminal computer operating in vehicles. is devised and made, the function is designed according to military road transportation also. The technologies about embedment、computer、GIS、 BEIDOU planet position and communication are all integrated in the terminal. Its functions contain...

Multimedia courseware has been widely used after the introduction of smart school project. This paper describes the development of the interactive courseware with embedment of Pedagogical Agents, Games Based Learning and Blended Learning elements. The focus of the courseware is Loci in Two Dimensions since most of the students have difficulties in understanding this topic. The combination of th...

The use of structural steel profiles as an external shear bracing is one the most preferable simple, time saving and cost-efficient strengthening method for inadequate existing reinforced concrete (RC) structure against earthquake lateral loads in comparison to other interrupting, irritating destructive traditional plane methods which need evacuation houses. With this method, inhabitants buildi...

In this paper, a new reversible data hiding method based on a dual binary tree of embedding levels is proposed. Four neighborhood pixels in the upper, below, left and right of each pixel are used as reference pixels to estimate local complexity for deciding embeddable and non-embeddable pixels. The proposed method does not need to record pixels that might cause underflow, overflow or unsuitable...
