Abstract: The invention refers to a multifunctional self-sustained hosting apparatus for photonic integrated circuit and/or related chipset system packaging comprising a processed wafer (1); and at least a cavity (2), wherein said cavity (2) is configured to receive a chipset or an optical lens; and at least a V-groove (3), which is configured for receiving at least an in/out optical fiber and optically align said optical fiber with an optical endface of a chipset. The invention also refers to a bidirectional optical sub assembly based on photonic integrated circuit, which comprises said hosting apparatus. The hosting apparatus enables PIC&IC co-packaging allowing to answer current and future requirements in diverse PIC applications.

Abstract: A method for unsupervised transformation of denormalized data into RDF data includes summarizing an existing resource description framework (RDF) file wherein a data summary file is produced, wherein said RDF file includes a plurality of nodes, property labels, and literals and is represented as a directed graph, and said data summary file is a graph that includes a single instance of each node-property-literal triple in the RDF file; analyzing a plurality of denormalized records wherein a record summary is produced, wherein said record summary is represented as a directed graph with a root node corresponding to each record connected to a node for each field in the record; determining one or more transformation patterns that match elements of the record summary to elements of the data summary; and transforming the plurality of denormalized records into a new RDF file by executing one of the one or more transformation patterns.

Abstract: A method of web-based data visualization includes: a Frontend sending a request over a computer network to a server configured as a Backend; a web server of the second server fetching data responsive to the request; the web server sending a response to the Frontend in a format compatible with a plurality software adaptors located on the Frontend, the response including information about objects to be presented on a web component; logic of the Frontend passing the response to a selected one of the software adaptors; and the selected software adaptor rendering the using a web visualization library associated with selected software adaptor.
