In the coordinate plane, A(−1,0), B(0,2), C is on the x-axis, and the area of △ABC is
Given: On a rectangular plane coordinate system xOy, point A is on the positive part of they-axis, AB / x-axis, point C is on the positive part of the x-axis, BC ⊥ x-axis, OA=BC=2, and OC=AB=3. Through the origin O, draw the bisector of ∠AOC, intersecting AB atD, and...

The Room Analogy to Explain Coordinate System in 3D Space Let’s take any corner of your room as the origin. The wall on your left and the floor of the room intersects through a horizontal line, it is the x-axis. The floor of the room and the wall on your right intersect through an...
Medical image segmentation is crucial in diagnosing and treating diseases, but automatic segmentation of complex images is very challenging. Here we present a method, called the crack propagation method (CPM), based on the principles of fracture mechanic
Keldysh: When the ponderomotive energy\({U}_{p}=\frac{{e}^{2}{E}^{2}}{4{m}_{e}{\omega }^{2}}\)for electric field strengthEand frequencyωis lower than the ionization potentialIp, the multiphoton ionization is dominant as a perturbative process wheren-number of photons are absorbed...
In our method, the computational load can be decreased, as one coordinate of the intersection point between the ray and an edge is known in advance, and parallel computing can be well exploited because the branching operations for determining whether an edge intersects with the ray are saved. ...
If the granule CC is enough small such that all points in CC correspond to a same result, then it is determinacy; when the granule CC is enough big such that CC intersects face and back both, in this case, the event occurred may be face or back, it becomes randomness....
the steering joint is considered as an ideal yaw rotational hinge placed at a distance of x G 1 from the front CoG and x G 2 from the rear CoG; the front and rear tracks width is equal to T ; the number of road wheels is N w = 4 for each track; flexible deformation of the tr...
The point cloud was transformed into a geographic coordinate system for registration, and the Random sample consensus (RANSAC) was used to segment it into ground and canopy. A 3D voxel prescription map with a unit size of 0.25 m was constructed from the tree canopy point cloud. The height ...
