1 dzień temu · The quaternion is called the vector part (sometimes imaginary part) of q, and a is the scalar part (sometimes real part) of q. A quaternion that equals its real part (that is, its vector part is zero) is called a scalar or real quaternion, and is identified with the corresponding real number.

It has evolved from a simple oasis and ksar (traditional settlement) to a city with a contrasting center and segregated outskirts. This growth has led to significant urban fragmentation that affected residents’ quality of life. This research uses space syntax theory to analyze Bechar’s ...

Each system is assembled into the corresponding rail segment according to the actual position of the rails. Multiple systems can correspond to the same rail segment.
