A computer system includes a host environment for the server, equipped with a port for communicating over an extended network and a network server to which is assigned a first network address or URL pathway. In some embodiments, the delivery device includes a stainless steel needle joined to a horn. The first alignment layer induces a first pretilt angle \u03b81 in the range of 20\xb0-65\xb0 between the liquid crystal layer in contact with the first alignment layer. The application of the pruning algorithm to VM deployment automation necessarily defines a new model.
