the initial nodes through a normal stochastic selection mechanism. Step 4: Query and evaluate contacts. Each node in cluster draws out a number of contacts for query. All the contacts coming from...;" is an AND operator; "^" is a XOR operator. According to the mask code mechanism, the network of search space can form a category tree model which is similar to a computer network structure. Group ID......

]. Also, they could not reliably predict the SWCC in the high range of suction, where capillary tension is overwhelmed by adsorption mechanism [23]. In addition, they involve complicated computation... (cation exchange capacity) and SAR (soil adsorption ratio, etc.) into the equation. To increase the accuracy, the water contents at several specific suction values (for example, 33 and 1500 kPa......
, regardless of its creative forces. To obtain the kinematic equations of a robot mechanism, each link is considered as a rigid body to describe the relationship between the two neighboring joint axes... systems, joints, joint angles, and centers of mass of the IRB-120 robot manipulator. Because all joints of the IRB-120 robot are revolute, the robot mechanism is 6-R (revolute). In the three joints......
sensors are among research projects addressing environmental concerns. The gas sensing properties of these sensors stem from the fact that the adsorption/desorption process of gases on metal oxide surfaces... between ammonia molecules and the sensor surface were weak physical forces, which were easily broken away when a stream of dry air was passed through. In addition, the other possible mechanism......

Globally, the main alumina extraction processes include the Bayer method... to the composition of bauxite and the alumina extraction process [50, 51]. However, the chemical composition of bauxite residue mainly includes Na2O, Al2O3, Fe2O3, SiO2, TiO2 and CaO. Approximately 95% of the global......
