Abstract: Reactor systems, reactor coolant systems, and associated processes for polymerizing polyolefins are described. The reactor systems generally include a reactor pipe and a coolant system, in which the coolant system includes a jacket pipe surrounding at least a portion of the reactor pipe to form an annulus therebetween, at least one spacer coupling the jacket to the reactor pipe, and a coolant which flows through the annulus to remove heat from the reactor pipe. At least one of the external surface of the reactor pipe, the internal surface of the jacket, and at least one spacer, are independently modified, for example by polishing, coating, or reshaping, to reduce the fluid resistance of the coolant flow through the annulus.

Abstract: A multi-leg transport system receives a transport request and determines a number of transfer locations between the origin location and the destination. The system selects a first provider to transport the user from the origin location to a transfer location and remotely monitors the position of the user as the user travels to the transfer location. In response to determining that the travel time to the transfer location is within a threshold, the system selects a second provider to transport the user from the transfer location to either the next transfer location or the destination for the transport request.

Abstract: Several API specification files that each include references to code elements that are defined within separate definitions and resources files may be merged together into a single specification for the new API. In this way, specifications for shared code elements that are common across the several specification files may be created without rewriting these specifications each time they are used in an API. A specification merging tool may look for a common reference in the API, match that reference to a definition or resource from the respective definition or resource document, and add that definition or resource to a merged specification file.

Abstract: A method for providing electronic business updates comprising receiving at least one account update from an account server relating to activity in a user account and determining that the account update is associated with an activity category. Based on the a determination generating an activity notification and, in response to receiving the at least one account update, pushing the activity notification to a user computing device to trigger a notification on the user computing device.

Abstract: In various implementations, methods and systems resource balancing in a distributed computing environment are provided. A client defined resource metric is received that represents a resource of nodes of the cloud computing platform. A placement plan for job instances of service applications is generated. The placement plan includes one or more movements that are executable to achieve a target placement of the job instances on the nodes. It is determined that the placement plan complies with placement rules. Each placement rule dictates whether a given job instance of the job instances is suitable for placement on a given node of the nodes. The placement plan is executed based on determining that the target placement of the job instances improves balance of resources across the nodes of the cloud computing platform based on the resource represented by the client defined resource metric.

Abstract: Systems and techniques are provided for presence and directional motion detection. Signals may be received from a sensor positioned in a structure. An indication of directional motion may be generated based on the signals from the sensor. The indication of directional motion may be generated without using signals from additional sensors. A control signal for a device in the structure may be generated in response to the indication of directional motion. The control signal may be sent to the device in the structure to be implemented by the device.

Abstract: Techniques for multi-tenant storage for analytics with push down filtering are described. A multi-tenant storage service can include resources can be grouped into racks, with each rack providing a distinct endpoint to which client services may submit queries. Each rack may include interface nodes and storage nodes. The interface nodes can preprocess queries that are received by splitting them into chunks to be executed by the storage nodes. Each storage node includes a field programmable gate array (FPGA) and a CPU. The CPU can receive the operations and convert the operations into instructions that can be executed by the FPGA. The instructions may include pointers to data and operations for the FPGA to perform on the data. The FPGA can process the data stream and return the results of the processing which are returned via the interface node.

Abstract: A process is described for introducing a catalyst into a polymerization zone by detecting one or a combination of (i) a change in a concentration of the catalyst in a catalyst feed stream upstream of the polymerization zone, (ii) a change in a concentration of monomer in the polymerization zone, and (iii) a change in a polymer production rate of the polymerization zone, adjusting a first catalyst flow rate of the catalyst in the catalyst feed stream to a second catalyst flow rate based on the one or a combination of (i), (ii), and (iii), and introducing the catalyst into the polymerization zone downstream of a location in the catalyst feed stream where the step of adjusting is performed. A catalyst injection system for carrying out such a process is also provided.

Abstract: An embodiment of the present invention is directed to a database actuator tool that makes data readily available and enable users to focus on solving the problem rather than searching for data. The database actuator tool represents a browser-based application that may be used to create, store and/or execute a repository of frequently used or needed queries, e.g., SQL queries, using a very friendly and easily configurable user interface. The database actuator tool provides a configure-once and usable-forever by anyone with right entitlements solution. This provides a substantial productivity boost to a team that has a mix of developers and non-developers, including users with and without SQL knowledge. The database actuator tool may be used by various teams and/or applications.

Abstract: Digital document editing techniques as part of electronic signature collection are described. These techniques support a single unified workflow in which comments and edits may be made as part of collecting an electronic signature. In this way, user and computational efficiency may be increased over conventional techniques that require initialization of the electronic signature collection workflow any time a comment or change is to be made to a digital document. Further, the comments and edits may be incorporated as part of audit trail associated with the electronic signature, thus increasing effectiveness of the electronic signature in providing supporting evidence of signature validity by documenting changes made to the digital document by one or more of the parties that sign the document.

Abstract: A transactional replicator applying group commit and barrier concepts is disclosed. Group commit means that the transactional replicator commits multiple transactions in a group and is not restricted to committing single transactions one-at-a-time and is not limited to operating on a single state provider. Barrier means that the transactional replicator does not move forward to commit additional transactions until the previous group of transactions are completed. All state providers must apply their transactions and update state before additional transactions will be committed. A quorum acknowledgement “unlocks” any locks that were acquired to update the state within a state provider. However, as long as there are no lock conflicts, additional transactions can continue to create new group commits as necessary.
