INTRODUCTION Medical education is experiencing rapid growth with an increasing number of publications and journals dedicated to education research.1,2 Several new journals and special education issues (including the CDEM/CORD supplement by the Western Journal of Emergency Medicine) have arisen in recent years to address this increasing interest. As clinician educators, it is important to produc...

This paper presents a terrain mapping and path planning techniques for a planetary exploration rover. A light detection and ranging (LIDAR) is employed in this work to obtain a point cloud data of the terrain feature. A terrain map converted from the point cloud data is represented with a sector-shaped reference grid, resulting in a digital elevation map with the cylindrical coordinate, called ...

In this paper, using the continuum-discontinuum element method (CDEM), fragmentation and outburst process of coal specimen are simulated, main factors affecting breaking explored. The results show that after seam is uncovered, generates obvious failure trend. Near coal-free surface, fracture blocks generate significant displacement, resulting in larger opening widths cracks. Coal deep cracks wi...

To simulate the propagation law of hydraulic fractures in deep Coal Bed Methane (CBM) reservoirs Qin-shui basin, a 3D numerical model is established using continuous-discontinuous algorithm, and discrete fracture network (DFN) included to increase its heterogeneity. The control variable method was employed study effects situ stress, random number, fracturing fluid flow viscosity on propagation....

Due to the high in situ stress of deep rock mass and restraining effect surrounding rock, hole blasting vertical shaft faces problems low borehole utilization rate poor effect. In this regard, paper proposes a multi-stage cut technology shaft. Preliminary engineering practice shows that such can make better use explosive energy, reduce increase rate. Furthermore, based on continuum-based discre...

The slope reinforcement scheme has an important influence on the prevention and control of landslides. A reasonable can improve reliability, economy efficiency landslide resistance. It is urgent to establish a local precise method for landslides basis clear process instability modes Taking high-steep anti-dip rock as example, six numerical models are established by using continuum–discontinuum ...

The Arrangement-Star is a well-known network in the literature and it is one of the promising interconnection networks in the area of super computing, it is expected to be one of the attractive alternatives in the future for High Speed Parallel Computers. The Arrangement-Star network has many attractive topological properties such as small diameter, low degree, good connectivity, low broadcasti...
