Semantic zoomable interface for multimedia content

Without any doubt multimedia content has become essential in all aspects of our digital society, leading to the generation and storage of an unfathomable amount of digital media. In the Information Retrieval (IR) field the majority of research available to this date approaches all questions in terms of semantic tagging, indexing and feature extraction. Although these are all fundamental steps in the design of any IR system, we believe that also an efficient human machine interface (HMI) can significantly improve the retrieval rate success at the end-user side. In our work we developed a Zoomable User Interface integrated with semantic algorithms dealing with media content, calling it a Semantic ZUI: we believe thath this approach can help browsing multimedia files in a seamless way, providing benefits for end users

Microfabrication of large-area circular high-stress silicon nitride membranes for optomechanical applications

In view of the integration of membrane resonators with more complex MEMS structures, we developed a general fabrication procedure for circular shape SiNx membranes using Deep Reactive Ion Etching (DRIE). Large area and high-stress SiNx membranes were fabricated and used as optomechanical resonators in a Michelson interferometer, where Q values up to 1.3 × 106 were measured at cryogenic temperatures, and in a Fabry-Pérot cavity, where an optical finesse up to 50000 has been observed.Electronic Components, Technology and MaterialsEKL ProcessingEKL-User
