Abstract: A method of processing off gas from a chemical plant, where the off gas includes carbon dioxide and water. The processing of the off gas involves separating the off gas into a gas phase and a liquid phase and using one or more ion-exchange resin bed(s) and one or more granular activated carbon bed(s) to separate unwanted organic materials from the liquid phase. Based on this separation, water can be recovered that has less than 10 wt. % of the unwanted organic compounds originally in the liquid phase of the off gas.

Abstract: Disclosed is a method, system, and computer readable medium to implement differential log file analysis using a computer device. The differential technique including obtaining one or more log file entries representative of successful test executions of a computer process. The computer process may execute on a single computer system or be a distributed application across multiple computer systems in a target environment. Acceptable deviations between log file entries associated with different instances of successful test executions may be used to creating a pattern matching representation in the form of a line pattern, sequence pattern, timing pattern, branching sequence pattern, cyclical sequence pattern, or a combination thereof. Matching of run-time log file entries against known success acceptable patterns may provide indication of system or application anomalies based on a failed comparison of the matching. A state machine implementation may be used to perform the matching function.

Abstract: Certain example embodiments relate to a coated article including at least one infrared (IR) reflecting layer of a material such as silver or the like in a low-E coating, and methods of making the same. In certain cases, at least one layer of the coating is of or includes nickel and/or titanium (e.g., NixTiyOz). The provision of a layer including nickel titanium and/or an oxide thereof may permit a layer to be used that has good adhesion to the IR reflecting layer, and reduced absorption of visible light (resulting in a coated article with a higher visible transmission). When a layer including nickel titanium oxide is provided directly over and/or under the IR reflecting layer (e.g., as a barrier layer), this may result in improved chemical and mechanical durability. Thus, visible transmission may be improved if desired, without compromising durability; or, durability may simply be increased.

A top dielectric layer may be formed over the first interface layer. The top dielectric layer may be formed using reactive sputtering in an oxygen containing environment. The first interface layer may prevent further oxidation of the partially oxidized alloy of the three or more metals when forming the top dielectric layer. A second interface layer may be formed over the top dielectric layer.
