Abstract: A method of forming an isocyanate-functional polymer component includes forming a first mixture by mixing a recycled polyurethane article and a first isocyanate component having isocyanate-functional groups. The first mixture is heated to a temperature sufficient to transform the recycled polyurethane article from a solid form to a liquid form and react the liquid recycled polyurethane component with the first isocyanate component to form an isocyanate-functional polymer component having an isocyanate-functional group content greater than zero and less than isocyanate-functional group content of the first isocyanate component. The formed isocyanate-functional polymer component may then be used for forming a polyurethane article or polyurethane foam article that is the reaction product of the formed isocyanate-functional polymer component, a second isocyanate component and an isocyanate-reactive component having hydroxyl-functional groups.

Abstract: Disclosed is an improved approach to implement cursor sharing in database systems, where a server-side mapping of cursor identifiers to SQL is maintained to allow for continued use of client-side statement caches even after connections and database sessions are returned to shared pools and then subsequently re-assigned. This avoids the need to clear the statement cache across session releases to the database session pools. Instead, applications can retain their statement cache while still leveraging the benefits of server based pooling solutions.

Abstract: A method includes introducing a fluoro-based small molecule tracer into a stimulation fluid, injecting the stimulation fluid into a target zone of a subterranean formation, and maintaining the fluoro-based small molecule tracer inside the target zone of the subterranean formation for an amount of time.

Disclosed process consists of two stages and in the first stage, shredded organic waste is digested in primary digester in which biodegradable organic fractions present in waste gets converted to volatile fatty acids and alcohols dissolved in aqueous solution by hydrolytic and acidogenic microorganisms. Primary digester effluent pH, is adjusted to about 6.8-7.5 by addition of controlled alkali solution. Neutralized waste slurry is separated into liquid solution called as leachate and digested solid sludge. In the second stage, liquid leachate comprising volatile fatty acids are converted to biogas with methane content in the range 80-86% by methanogenic microbial culture in main digester under anaerobic conditions.

Abstract: Methods, systems, and devices for data management are described. A server hosted by a storage node within a cluster of a data management system (DMS) may receive a request to access a file stored in a distributed file system. The request may be associated with a security identifier (SID). The server may transmit an indication of the SID to a shared repository accessible to the cluster. Accordingly, the server may receive an indication of a mapping between the SID and one or both of a user identifier (UID) or a group identifier (GID) associated with the SID. The server may transmit an indication of the file and the UID/GID to the distributed file system, which may compare the UID/GID to a list of authorized identifiers for the file. If the UID/GID is on the list of authorized identifiers, the distributed file system may execute the request accordingly.

Abstract: A process for service chain instance pool sizing receives service requests for processing in a 5G network by a service function chain, of the 5G network, providing network function(s) to process the service requests. The method determines an average number of service requests to be processed, and determines a number of service chain instances to exist in a pool of service chain instances, of the service function chain, as a composite of (i) a number of instances to process service requests having arrived and making an initial relay through the service function chain and (ii) a number of instances to process service requests that were re-introduced after having previously arrived. The method additionally indicates the number of service chain instances to exist in the pool to a component responsible for controlling the number of service chain instances in the pool.

Abstract: Example implementations relate to connecting an IoT device to a wireless network using Device Provisioning Protocol (DPP). An authentication server receives a DPP network access authorization request including a connector identifier from an Access Point (AP) in communication with the IoT device. The connector identifier is a hash of the public network access key of the IoT device. If the connector identifier is valid, the authentication server determines a configurable policy from a set of configurable policies that is applicable to the IoT device. The authentication server transmits network permissions defined in the configurable policy to the AP. The IoT device is connected to the wireless network by the AP based on the network permissions.
