Abstract: The present disclosure relates to a method for a weighting graph comprising nodes representing entities and edges representing relationships between entities in accordance with one or more domains. The method comprises: pre-processing the graph comprising assigning weights to the nodes and/or the edges of the graph in accordance with a specific domain of the domains, wherein the weight indicates a domain specific data quality problem of attribute values representing an edge of the edges and/or an entity involved in that edge. The weighted graph may be provided for enabling a processing of the graph in accordance with the specific domain.

Abstract: In the cryogenic processing of a gaseous stream, the level of a first contaminant is adjusted, such as by recycling first contaminant already removed or by adding first contaminant, to maintain the total concentration of first contaminant in the gaseous stream at a level sufficient to dissolve the total amount of a second contaminant which would otherwise freeze-out, whereby the likelihood of freeze-out of the second contaminant is substantially reduced during cooling of the gaseous stream to cryogenic processing temperatures.

Abstract: A signal processor for an incremental encoder to provide output signals representing absolute position in any of a plurality of selectable scales and formats. In particular, incremental pulse signals from an incremental encoder are applied to a dedicated digital processor which is controlled by a read-only-memory to operate on the incremental input signals in a predetermined sequence of operations with associated logic units. To provide different output formats and scale factors, different processing of the incremental signals is provided by the same or different read-only-memory provided for operation with the system.

Abstract: A system for processing data from an incremental or other type of positional encoder and for displaying positional information in which individual digits are sequentially processd to provide the positional data. The invention results in simple circuitry, allows the number of axes served by the display/processor to be increased with minimal changes in processor hardware; and allows encoder movements to be displayed in different units of measurement, selectable by an operator.
