Abstract: A computer system is described. During operation, the computer system may receive information specifying communication in a network. Then, the computer system may detect a network problem based at least in part on the information. Moreover, the computer system may automatically determine a remedial action based at least in part on the detected network problem and may automatically perform the determined remedial action. Alternatively, when the remedial action cannot be determined, the computer system may selectively collect additional information for a predefined time interval, e.g., using one or more edge electronic devices or one or more controllers in the network. Next, the computer system may diagnose the network problem and may compute a second remedial action based at least in part on the diagnosis of the network problem. After receiving approval the computer system may automatically perform the second remedial action when a subsequent instance of the network problem is detected.

Abstract: Catalytic system for polymerization of lower alpha alkene including a selectivity control agent which consists of naturally derived pure isomers of tartrates such as esters of (2-R,3-R)-dihydroxy-butane-1,4dicarboxylic acid or (2-S,3-S)-dihydroxybutane-1,4-dicarboxylic acid. The molar ratio of the optically pure isomers of the tartrates to titanium being 0.0375 to 1.5.

Abstract: Single step process for the preparation of lower ?-alkene polymerisation heterogeneous solid catalyst, wherein the procatalyst is obtained by reacting organomagnesium precursor and titanium tetrahalide or titanium haloalkoxo species of the formula Ti(OR)m Xn, with a hydrocarbon or halohydrocarbon solvent and internal electron donor and optionally an acid halide under microwave irradiation of 300 to 1200 W. The mole ratio of the organomagnesium precursor to the titanium tetrachloride or titanium haloalko species is 1:6 to 1:20 and the mole ratios of the electron donor and acid halide to titanium is 0.3 to 1.5 and 0.02 to 0.2, respectively.
