We have developed a new parameter estimation method for Doppler wind spectra in the mesosphere observed with an MST radar such as the MU radar in the DBS (Doppler Beam Swinging) mode. Off-line incoherent integration of the Doppler spectra is carried out with a new algorithm excluding contamination by strong meteor echoes. At the same time, initial values on a least square fitting of the Gaussia...

In a strapdown magnetic compass, heading angle is estimated using the Earth's magnetic field measured by Three-Axis Magnetometers (TAM). However, due to several inevitable errors in the magnetic system, such as sensitivity errors, non-orthogonal and misalignment errors, hard iron and soft iron errors, measurement noises and local magnetic fields, there are large error between the magnetometers'...

DNA swingarms enable the efficient and reliable translocation of multiple optical elements along a shared origami track. Na Liu et al. demonstrate in their Research Article (e202213992) that dynamic rearrangement AuNPs with large leaps space can be facilitated by swinging motion, which is substantiated distinct response changes. >DNA Single-Atom Catalysts Polymers MXene

To ensure that the robot can follow planned trajectory, smooth switching between swinging legs and a transition of motion process is realised. The previous planning work analysed, method for improving optimisation objective function constraint conditions proposed to eliminate sudden change acceleration reduce peak value change. This eliminates impact phenomenon in motor drive reduces energy con...

In the field of minimally-actuated robots, energy efficiency and stability are two of the fundamental criteria that can increase autonomy and improve task-performance capabilities. In this paper, we demonstrate that the energetic cost of leg swinging in dynamic robots can be reduced without significantly affecting stability by emulating the physiological use of passive joint stiffness, and we s...
