Ultrasound B-scan images are traditionally formed from the envelope of the received radiofrequency echoes, but the image texture is dominated by granular speckle patterns. Longstanding efforts at speckle reduction and deconvolution have been develope

The use of green roofs, a low-impact development practice, can be an effective means of reducing direct runoff in urban centers. Green roof modeling can enable efficient design by preliminarily grasping the behavior of the green roof system according

A 4-CPS/UPU parallel mechanism used in the field of parallel machine tools is proposed. Based on the screw theory, the kinematic and constrained screw system of the parallel mechanism is established. The mechanism has five degrees of freedom and can

A worktable of 3-SPS/UPR parallel mechanism is proposed, which is used to assist the less degree of freedom machine tool to process the surface of the workpiece. The kinematic screw matrix of the 3-SPS/UPR parallel mechanism is established; its degre

Ultrasound measurements are a widely used instrument in clinical practice. For later traceability of the images, the position (and orientation) of the ultrasound probe must be recorded during the measurement. Until now this has to be done manually by

We propose a two-step procedure for atomic decomposition of multichannel EEGs, based upon multivariate matching pursuit and dipolar inverse solution, from which atoms representing relevant EEG structures are selected according to prior knowledge. We
