Abstract: A database system with a transactional commit protocol based on a safe conjunction of majorities is disclosed. In various embodiments, a directed acyclic graph comprising, for each of a plurality of database transactions, data identifying the transaction, data indicating one or more prior database transactions on which the database transaction depends, and data indicating whether the transaction has been committed is stored. A leading edge comprising a set of committed leaf nodes of the directed acyclic graph is determined. Data representing the leading edge is provided to a transaction coordinator configured to use the leading edge to determine based at least in part on the leading edge to commit a transaction.

Abstract: A computer-based decisioning tool is disclosed that enables the generation of Bias Assessment Scores to indicate a level of hidden or unconscious bias an individual being tested may have and enables the generation of Confidence Index Scores the indicate the best choices for making three types of decisions, which are searching/match decisions, comparison decisions, and binary (Yes/No) decisions.

Abstract: A composition for making a polyurethane foam includes a non-fugitive tertiary amine urethane catalyst and amidoamine and/or imidazoline crosslinking additives. Foams prepared from the reaction of a polyol and an organic isocyanate in the presence of these ingredients show excellent resistance to deterioration of physical properties upon humid ageing.

Abstract: Methods for preparing polyurethane flexible foam are described, wherein an organic polyisocyanate is reacted with an active hydrogen-containing component such as an organic polyol, in the presence of a urethane catalyst, a blowing agent, optionally a cell opener, and a siloxane-based surfactant composition as a stabilizer for the foam. The siloxane-based surfactant composition comprises a silanol-functionalized organosiloxane having general formula (I), wherein: the R groups are independently a C1-C3 alkyl, phenyl, or —OSi(R)3; provided that at least one R group is a hydroxyl (—OH) bonded directly to any silicon atom and X is an integer from 0-200.

Abstract: Catalyst compositions for use in forming polyurethane products include a gelling catalyst, a trimerization catalyst, and a cure accelerator. The gelling catalyst is a tertiary amine, mono(tertiary amino) urea, bis(tertiary amino) urea, or a combination of any of these. Any known trimerization catalyst may be used. The cure accelerator may be a diol having at least one primary hydroxyl group, and having from five to 17 chain backbone atoms chosen from carbon, oxygen, or both between the hydroxyl groups, provided that at least five of the backbone atoms are carbon. Alternatively or in addition, the cure accelerator may be a polyol having three or more hydroxyl groups, at least two of which are primary, and having molecular weights between 90 g/mole and 400 g/mole. Delayed initiation of the polyurethane-forming reaction and/or reduced demold time for producing the polyurethane part can be obtained by using these catalyst compositions.

Abstract: A Custom Control Generator automatically generates custom controls for selected modules (i.e., externally-accessible functions or procedures) in a dynamic link library (DLL). The Custom Control Generator accepts as input the library itself, header files for the library, and a specified calling sequence of selected modules within the library. The Custom Control Generator then generates as output a shell program, wherein the shell program comprises source code for a user-interface for invoking the selected module in an interactive manner.
