Bridging the Gap between Semantics and Multimedia Processing

Roberto Gerson De Albuquerque Azevedo

In this paper, we overview the semantic gap problem in multimedia and discuss how machine learning and symbolic AI can be combined to narrow this gap. We describe the semantic gap in terms of a classical architecture for multimedia processing and discuss a ...

Flexible support and enhanced groove geometries for gas lubricated bearings

Philipp Kaspar Bättig

Gas lubricated Herringbone-Grooved Journal Bearings (HGJB) are a promising solution to support high-speed rotors in oil-free turbo-machinery due to their compactness, relatively low losses, no need for lubrication and low wear. Gas lubricated bearings, how ...

A High-performance FPGA Architecture Using One-Level RRAM-based Multiplexers

Giovanni De Micheli, Xifan Tang, Pierre-Emmanuel Julien Marc Gaillardon

Resistive Random Access Memory (RRAM)-based routing multiplexers, built using a one-level structure, are significantly more delay efficient than state-of-art SRAM-based implementations thanks to their lower achievable on-state resistance. In addition, the ...

Optimization Opportunities in RRAM-based FPGA Architectures

Giovanni De Micheli, Xifan Tang, Pierre-Emmanuel Julien Marc Gaillardon

Static Random Access Memory (SRAM)-based routing multiplexers, whatever structure is employed, share a common limitation: their area, delay and power increase linearly with the input size. This property results in most SRAM-based FPGA architectures ...
