The computing platform may transmit the invoice to an enterprise organization for modifications and may receive, from the enterprise organization, confidential data including a modified invoice. The computing platform may receive, from an entity associated with a transaction indicated on the invoice, a request to access the modified invoice using a mixed reality application. The computing platform may receive, from the entity and based on the entity's review of the modified invoice using the mixed reality application, approval to execute the modified invoice.

Abstract: Processes integrating electric heaters or other heating sources for heating of liquid and two phase hydrocarbon streams resulting in reduced CO2 emissions are described. The processes shift a portion of the fired heater duty to an electric heater or other heat source. All or a portion of a vapor stream from a two phase separator is heated or superheated by an electric heater or other heat source to provide sufficient temperature that the heated/superheated vapor stream acts as a heat source to a bottom or side draw stream from a column. The preheated bottom or side draw stream is sent to the fired heater.

Abstract: A fluid catalytic cracking process for p-cresol dimer to produce valuable phenolic monomers, i.e., 2-methyl phenol, 4-methyl phenol, 2,3-xylenol, and phenol, uses an equilibrium catalyst (E-cat) generated in the petroleum fluid catalytic cracking (FCC) unit. The p-cresol dimer can be processed under relatively mild conditions, while maximizing desired and minimizing undesired products.

Abstract: Examples of file analytics systems are described that may obtain event data from a virtualized file server. The event data may be aggregated and/or filtered to provide metrics. The file analytics system may obtain event data from the virtualized file server. The file analytics system may process multiple streams of event data in parallel by separating messages corresponding to the event data message topic into multiple partition pipelines. To avoid processing events related to a particular file out of chronological order, the analytics tool may distribute events for the particular file to the same message topic partition pipeline.

Abstract: Flows corresponding to an overlapping IP address are differentiated via scalable techniques for appropriate enforcement security policies. Agents deployed to each site of a network (e.g., each VPC or branch router) encapsulate outbound packets with a header that includes an identifier that uniquely identifies the site as the origin of the packets, such as a VPC identifier or branch identifier. A session manager executing on a security appliance receives the encapsulated packets and determines the origin identifier and other packet attributes, including source/destination IP addresses, source/destination ports, and protocol. The session manager creates an N-tuple (e.g., a 6-tuple) comprising the origin identifier and packet attributes and creates a session for the flow with the N-tuple as the session key. The security appliance then enforces a security policy for the packets and subsequent packets that are part of the flow and match to the created session.
