IT outsourcing has three broad forms: (i) Single-Sourcing, where the client outsources to one primary vendor, (ii) Single-Sourcing with subcontracting , where the primary vendor involves other/secondary vendors in the project, and (iii) Multi-Sourcing, where the client outsources to multiple primary vendors. Using a dataset of large IT outsourcing contracts from the SCD database with 22,031 lar...

Communication speed in a parallel and distributed system is related to the diameter of its underlying graph. The diameter of a graph can be affected by the addition or deletion of edges. In this paper we study how the diameter variability problem arises from change of edges of an m × n diagonal mesh, where m and n are not both even integers. We show that the least number of edges whose deletion...

Communication speed in a network is related to its diameter. The diameter variability arises from the changes of links from networks. In this paper we study how the diameter of Kronecker product of cycles changes by adding edges.

The effect of lattice mismatch on the chemical ordering of epitaxial FePt films was studied. The results showed that the lattice constant scd of the FePt films decreased with increasing lattice mismatch « from about 2.23% to 6.33%. Upon further increase of « to about 8.8%, c increased. On the other hand, the variation of the lattice constant sad of the FePt films showed a reversal behavior to t...

Use of jet cavitation, however, occurs through an exit nozzle whose diameter can be changed, thereby changing volume with changing velocity. The results of such a change is shown to tie cavitation damage more powerfully to volume flow than to velocity. A specific example is in cavitation erosion of a high strength igneous rock which remained virtually undamaged at 70 MPa driving pressure but wa...
