A diode rectifier-modular multilevel converter AC/DC hub (DR-MMC Hub) is proposed to integrate offshore wind power the onshore DC network and production platforms (e.g., oil/gas hydrogen plants) with different voltage levels. The DR MMCs are connected in parallel at AC collection power, series terminals of platform network. Compared conventional parallel-connected DR-MMC HVDC systems, reduces r...

The knowledge graph, which is an ontology based representation technique, is described to model the information necessary to conduct collaborative filtering, content-based filtering and knowledge based recommendation methods. Spreading activation and network science based recommendation methods are presented and evaluated. The evaluation measures are calculated on top list recommendations, wher...

This paper presents an expert system aimed at evaluating firms and business units. It makes us of fuzzy logic and integrates financial, strategic, managerial aspects, processing both quantitative and qualitative information. Twenty-nine value drivers are explicitly taken into account and combined together via “if-then” rules to produce an output. The output is a real number in the interval [0,1...

The increasing popularity of open innovation approaches has lead to the rise of various innovation platforms on the Internet which might contain 10.000s user-generated ideas. However, a company’s absorptive capacity is limited regarding such an amount of ideas so that there is a strong need for mechanism to identify the best ideas. Extending previous decision management research we focus on ana...
