Invention refers to the pneumatic transport field, namely to vacuum-pneumatic transportation of bulk materials of high mass concentrations. A long-term representation and a short-term representation of the field of view are constructed, and a difference between the long-term representation and the short-term representation is calculated. The method collects the data elements of the data set. The SDN controller compares the provisioning data from the first network provisioning application to the provisioning data from the second network provisioning application to identify provisioning issues. The seal assembly comprises a first member and a seal carrier mounted to the first member by a mounting member, a second member spaced from the first member and a seal running member positioned on a second member, and a hydraulic seal for preventing gas leakage from a high pressure source to a low pressure compartment through the mounting member. At least one higher-melting noncontinuous phase comprises a polypropylene polymer with melt flow rate of greater than 20 g10 min.
