  • Bridging the gap between haptic devices and cobots with highly geared magnetorheological actuators

    Bridging the gap between haptic devices and cobots with highly geared magnetorheological actuators

    System level

    The analysis framework is transposed from internal combustion engines world27 and based on the concept of an actuator’s “brake” torque. The brake torque is a measurable output torque found by subtracting the “frictional”…

  • Relative DOA estimation method for UAV swarm based on phase difference information without fixed anchors

    Relative DOA estimation method for UAV swarm based on phase difference information without fixed anchors

    UWB transceiver can measure carrier phase more precisely than time-of-flight, the typical error value is less than 3°, which corresponds to 0.06 cm at fc = 3.9936 GHz. Time difference measurements error is about 1600 times higher than phase…

  • A novel approach for music genre identification using ZFNet, ELM, and modified electric eel foraging optimizer

    A novel approach for music genre identification using ZFNet, ELM, and modified electric eel foraging optimizer

    After performing data preprocessing and acquiring spectrograms, the data is then subjected to the ZFNet/Extreme Learning Machine (ELM) approach for the goal of data modification, extraction of features, and recognition.

    To extract the features of…

  • Titan’s rivers end in deep pits, not deltas, defying expectations

    Titan’s rivers end in deep pits, not deltas, defying expectations

    A study has just dashed hopes of finding water on Saturn’s largest moon, Titan.

    Researchers recently searched for deltas on Saturn’s largest moon, Titan, but came up empty.

    While Titan features rivers and seas of liquid methane, it…

  • Artificial lily pads boost lithium yield, cutting time and land use

    Artificial lily pads boost lithium yield, cutting time and land use

    South America’s lithium triangle is home to vast evaporation ponds that quietly produce lithium, often called white gold, which powers our phones, electric cars, and batteries.

    These ponds, fed by mineral-rich brines, supply nearly 40% of…
