A method for operating a flow-based switching system in a network, including at least one network node designed to transport incoming network packets, in particular a switch (20) or a router, wherein the incoming network packets are matched to flows according to predefined policies, wherein a dynamic flow table (40)—primary flow table (50)—containing information about the flows' properties is computed inside the network node or externally and stored in a memory of the network node, is characterized in that another dynamic flow table (40)—backup flow table (60)—is computed and maintained in parallel, wherein the backup flow table (60) is more coarse grained than the primary flow table (50), and wherein the network node switches between employing the primary flow table (50) or the backup flow table (60) depending on the status of predefined observables. Furthermore, a corresponding flow-based switching system is disclosed.

A method for energy consumption monitoring in an ICT environment, wherein the ICT environment (1) includes a multitude of energy consuming components (2, 3), at least partly the components (2, 3) being instrumented with elements for energy consumption monitoring and/or having assigned specific energy consumption models that derive one or more energy metrics for the respective component (2, 3) from the component's (2, 3) current performance metrics, is characterized in the steps of ascertaining changes of and/or related to the ICT environment (1) via an energy consumption monitoring controller (7), performing an assessment of available energy consumption monitoring techniques both instrumentation-based and model-based, based on the result of the assessment selecting one or more energy consumption monitoring techniques that best satisfy the change of the ICT environment (1) according to predefined policies. Furthermore, a corresponding monitoring system is described.
摘要:
Process for recovering molybdate or tungstate from an aqueous solution, in which molybdate or tungstate is bound to a water-insoluble, cationized inorganic carrier material from the aqueous solution at a pH in the range from 2 to 6, the laden carrier material is separated off and the bound molybdate or tungstate is liberated once again into aqueous solution at a pH in the range from 6 to 14. The process is suitable for recovering molybdate or tungstate in the delignification of pulp with hydrogen peroxide in the presence of molybdate or tungstate as catalyst. The recovered molybdate or tungstate can be recycled to the delignification.
摘要:
A method for supporting distribution of warning messages, is characterized in that an NGN (Next Generation Network) infrastructure is employed for distribution, wherein the infrastructure includes a plurality of network elements including endpoints, wherein a hierarchical architecture is defined for the network elements, wherein groups of network elements including endpoints with specific characteristics are defined, wherein each of the network elements provides its group membership information to at least one higher-tier network element, and wherein at least one group warning controller is provided that, upon receiving a request from a source node, generates a warning message for one or more target groups and forwards the warning message to lower-tier network elements of the respective target group or groups towards endpoints.
摘要:
The delignification and bleaching of chemical pulp by a bleaching stage, in which the chemical pulp is reacted first with chlorine dioxide and, after reaction of the chlorine dioxide, is further reacted without intermediate washing with hydrogen peroxide in the presence of a molybdate or tungstate, permits the production of chemical pulp having a whiteness of at least 89.5%, having improved stability to yellowing and reduced oxidative damage.

摘要:
The invention relates to organosilanes and organopolysiloxanes which contain 2-oxazolidinone groups, where the oxazolidinone group is linked by the ring carbon atom C-4 or C-5 via a spacer to the silane or siloxane and the spacer is connected via a hydrolysis-stable Si--C bond to the silane or siloxane, their use as surface-active substances and also their use for preparing organosilanes and organopolysiloxanes containing amino or carbamido groups.
摘要:
A multi-layer headbox for the production of a multi-layer web of paper has, for instance, three flow planes (I, II, III), each having a pulp feed device (1.1, 1.2, 1.3). In each flow plane a turbulence generator (3) is provided which opens into a nozzle (4). In it there are two plates (5.1, 5.2) which keep two neighboring streams of slurry separate from each other up to the region of the exit slot (8). Each plate is developed as a flexurally soft plate of plastic, the downstream end of which is metal and has a thickness S of at most 0.3 mm. The plastic and metal have a different in coefficients of thermal expansion of
摘要:
A multilayer headbox for the introduction of at least two fiber suspension streams to the forming section of a paper manufacturing machine includes a nozzle chamber further defined by two stream guide walls which end at an outlet gap and by two side walls. At least one lamella is provided in the nozzle chamber, this lamella keeping at least two fiber suspension streams separated from each other through the region of the outlet gap. The lamella includes a body, preferably made of plastic, and a tip made of a hard material. The tip is either a strip or a coating having a sharp tip-edge integrated into the body of the lamella.
