We identify a class of two‐dimensional systems, including many standard equations of compressible flow, which are simplified by a transformation to similarity variables. For equations in this class, a two‐dimensional Riemann problem with sectorially constant data becomes a boundary‐value problem in the finite plane.
Motion along a curved path on a flat surface or a plane (such as that of a ball on a pool table or a skater on an ice rink) is two-dimensional, and thus described by two-dimensional kinematics.
Motion not confined to a plane, such as a car following a winding mountain. Co–Ni-hydroxide precursors were prepared by hybrid quasi-two-dimensional nanosheets and hetero-oriented nanocrystallines walls. Followed by dip-dry and annealing, NiCo 2 O 4 could adhere to the nickel foams robustly with a solution-based surface treatment.
Moreover, an unusual phenomenon in the electrochemical test inspired us to establish a. Apply problem-solving steps and strategies to solve problems of one-dimensional kinematics. In one-dimensional kinematics and Two-Dimensional Kinematics we will study only the motion of a football, for example, without worrying about what forces cause or change its motion.
Such considerations come in other chapters. Want to cite, share. We represent positions on that plane with ordered pairs. For this example: PC BC * PN 1 y To find the midpoint, which is also an ordered pair, use the formula M м x + x2 + y2 2 2 Find and label the midpoint of this two-dimensional segment: M 3.

How to use two-dimensional in a sentence. According to two-dimensional semantics, the meaning of an expression involves two different "dimensions": one dimension involves reference and truth-conditions of a familiar sort, while the other dimension involves the way that reference and truth-conditions depend on the external world (for example, reference and truth-conditions might be held to depend on which individuals and substances.
Abstract. We consider the two-dimensional geometric knapsack problem defined as follows. Given a collection of rectangular axis-parallel items with weights, we want to find a maximum weight subset of the items that can be packed into a rectangular knapsack, i.e., which can be assigned positions within the knapsack such that the items are pair-wise non-overlapping.

A useful means of constructing approximate flow models is the hydraulic (for two-dimensional problems quasi-one-dimensional) approach, based on averaging the initial nonuniform flows over some direction or cross section .
In this case, at the expense of a rougher model it is possible to reduce the dimensionality of the problem. Here, this approach is extended to unsteady two-dimensional gas. A quasi two-dimensional benchmark experimental model has been established.
