Thus sequentially continuous functions "preserve sequential limits". The shape of the spirals depends on the growth of the elements generated sequentially. Sometimes the uppermost sheets bled into others, generating a sequentially developing series of images. These steps can be executed sequentially or in parallel. Packets are processed by sequentially traversing the rules in chains. However, forcing transactions to be processed sequentially is inefficient. It follows from the preceding discussion that reflexive spaces are weakly sequentially complete. Sequentially numbered queue cards were introduced in 2003. The following digit is a sequentially assigned number. Similar analyses were done on tires, which were known to be sequentially numbered. Testing can be conducted sequentially or in parallel. Rules can be solved in parallel in hardware, or sequentially in software. US models also included sequentially numbered GT3-R sill treadplates. Standard designations usually consist of a letter prefix and a sequentially assigned number. Superscalar processors are suited for optimising the execution of sequentially constructed fragments of code.
