A computer program product is provided for use with a computer system to execute a simulation. The network includes a storage system configured to store data, a server configured to process requests, a switch coupling the storage system and the server for data communication, and a network manager including an event dictionary to interpret an event message received from a device experiencing failure. The SOI substrate is formed by forming an opening into a structure that includes at least a first semiconductor layer and a second semiconductor layer that have different crystal orientations. The boot has a distal end mounting over the proximal end of the housing and a proximal end and defines a central axis. 03 meqg; from about 20 to about 60 equivalent percent of a polytetramethylene ether glycol having a molecular weight less than 1000 Da; and from about 25 to about 65 equivalent percent of a polytetramethylene ether glycol having a molecular weight greater than or equal to 1000 Da.
