University of California Berkeley researchers have designed an extreme-weather proven, hand-held device that can extract and convert water molecules from the air into drinkable water using only ambient sunlight as its energy source, a study published in Nature Water shows. from Tech Xplore - electronic gadgets, technology advances and research news https://ift.tt/BOY7KFQ

Reservoir computing is a promising computational framework based on recurrent neural networks (RNNs), which essentially maps input data onto a high-dimensional computational space, keeping some parameters of artificial neural networks (ANNs) fixed while updating others. This framework could help to improve the performance of machine learning algorithms, while also reducing the amount of data required to adequately train them. from Tech Xplore - electronic gadgets, technology advances and research news https://ift.tt/venU8QP

Two teams of solar-power engineers, one led by a large group at Helmholtz-Zentrum Berlin für Materialien und Energie GmbH, the other led by a group at École Polytechnique Fédérale de Lausanne, has found two ways to improve the efficiency of solar cells by getting silicon and perovskite to work together better. Both teams have published papers in the journal Science outlining the details of their work and the results of their testing. Stefaan De Wolf and Erkan Aydin, with the King Abdullah University of Science and Technology, have published a Perspectives piece in the same journal issue outlining the work done by both teams. from Tech Xplore - electronic gadgets, technology advances and research news https://ift.tt/1MJqTmR
