Copying compressed pages without uncompressing the compressed pages
Methods, devices and systems to make compressed backup copies of in-use compressed database indices are described. In general, an “oldest” time at which index pages in working memory had been updated is identified.

Method for the interaction of an operator with a model of a technical system
The method provides detection of a plurality of spatial parameters which are assigned to one or both forearms of an operator. Processing markers generated from the spatial parameters are visualized in a virtual scene.

Distributed energy resources (DER) such as photovoltaic arrays are becoming prevalent in distribution systems. These DER systems inject power into the distribution system which can cause unfavorable changes, such as a rise in voltage across the feeder lines of the distribution system. Existing control proposals suffer from a number of shortcomings, drawbacks and disadvantages. In some instances, traditional controllers for distribution systems with DER systems may require information related to the arrangement of the distribution system which is unknown and cannot be provided by the advanced metering infrastructure.
