Recording and conserving the millions of artefacts uncovered annually from excavation sites is a daunting task for archaeologists, but the 3D MURALE project has developed an integrated set of multimedia tools to help archaeologists preserve Europes ancient remains.
The 3D acquisition systems developed during the recently completed IST programme-funded project can measure a range of objects of different dimensions such as pottery shards and statues to produce precise, realistic-looking 3D models. After documenting and classification, these virtual artefacts are stored in a database with MPEG7 compatible features, allowing searching on the basis of 3D shapes. The scanning capabilities even allow for the reconstruction of excavated archaeological sites for the different periods of their occupation, providing an integrated visualisation of landscape, buildings, and artefacts true to the era that they represent.
"The 3D MURALE project has developed the first ever integrated set of multimedia tools for archaeologists," says project manager John Cosmas. Moreover, the projects results will make all kinds of archaeological evidence, either on site or in a museum, accessible to larger audiences of non-specialists.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
