How2Sign: A Large-scale Multimodal Dataset for Continuous American Sign Language
One of the factors that have hindered progress in the areas of sign language
recognition, translation, and production is the absence of large annotated
datasets. Towards this end, we introduce How2Sign, a multimodal and multiview
continuous American Sign Language (ASL) dataset, consisting of a parallel
corpus of more than 80 hours of sign language videos and a set of corresponding
modalities including speech, English transcripts, and depth. A three-hour
subset was further recorded in the Panoptic studio enabling detailed 3D pose
estimation. To evaluate the potential of How2Sign for real-world impact, we
conduct a study with ASL signers and show that synthesized videos using our
dataset can indeed be understood. The study further gives insights on
challenges that computer vision should address in order to make progress in
this field.

Legal situation and current practice of waste incineration bottom ash utilisation in Europe
Almost 500 municipal solid waste incineration plants in the EU, Norway, and Switzerland generate about 17.6 Mt/a of incinerator bottom ash (IBA). IBA contains minerals and metals. Metals are mostly separated and sold to the scrap market and minerals are either disposed of in landfills or utilised in the construction sector. Since there is no uniform regulation for IBA utilisation at EU level, countries developed own rules with varying requirements for utilisation. As a result from a cooperation network between European experts an up-to-date overview of documents regulating IBA utilisation is presented. Furthermore, this work highlights the different requirements that have to be considered. Overall, 51 different parameters for the total content and 36 different parameters for the emission by leaching are defined. An analysis of the defined parameter reveals that leaching parameters are significantly more to be considered compared to total content parameters. In order to assess the leaching behaviour nine different leaching tests, including batch tests, up-flow percolation tests and one diffusion test (monolithic materials) are in place. A further discussion of leaching parameters showed that certain countries took over limit values initially defined for landfills for inert waste and adopted them for IBA utilisation. The overall utilisation rate of IBA in construction works is approximately 54 wt.%. It is revealed that the rate of utilisation does not necessarily depend on how well regulated IBA utilisation is, but rather seems to be a result of political commitment for IBA recycling and economically interesting circumstances

Preparing for the phase B of the E-ELT MCAO module project
The Multi-Conjugate Adaptive Optics module for the European Extremely Large Telescope has been designed to achieve uniform compensation of the atmospheric turbulence effects on a wide field of view in the near infrared. The design realized in the Phase A of the project is undergoing major revision in order to define a robust baseline in view of the next phases of the project. An overview of the on-going activities is presented
