Advanced Photonics Research, EarlyView.Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...

Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%
Advanced Robotics Research, EarlyView.Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...

The urban screen as a socialising platform: exploring the role of place within the urban space [PDF]
, 2008 In this paper we explore shared encounters mediated by technologies in the urban space. We investigate aspects that influence the interactions between people and people and people and their surroundings when technology is introduced in the urban space ...

Learning to Place New Objects in a Scene [PDF]
arXiv, 2012 Placing is a necessary skill for a personal robot to have in order to perform tasks such as arranging objects in a disorganized room. The object placements should not only be stable but also be in their semantically preferred placing areas and orientations. This is challenging because an environment can have a large variety of objects and placing areas

The Global Warming Potential of Geoengineering via Radiative Cooling
Advanced Sustainable Systems, EarlyView.The cooling power of engineered radiative cooling materials is determined and compared to conventional construction and roofing materials and Earth's natural surfaces. Results show if 1% of Earth's surface are to be covered with state‐of‐the‐art radiative cooling materials the terrestrial radiative forcing would decrease by 1.61 W·m−2 (from 0.6 to −1 ...
