The blade design method comprises: obtaining target design parameters comprising a diameter of an impeller and the number of blades; determining a chord length of the blade according to the diameter of the impeller; according to the chord length of the blade, determining a camber of the blade corresponding to the chord length of the blade by means of a fitting optimization curve of the chord length and the camber; determining a height of the blade according to the diameter of the impeller and the number of blades; and obtaining an element of the blade according to the camber of the blade, and stretching a height of a corresponding position of the element of the blade to the height of the blade to obtain a target blade structure.

Abstract: In one embodiment, an emergency vehicle detection system can be provided in the ADV travelling on a road to detect the presence of an emergency vehicle in a surrounding environment of the ADV using both audio data and visual data. The emergency vehicle detection system can use a trained neutral network to independently generate a detection result from the audio data, and use another trained network to independently generate another detection result from the visual data. The emergency vehicle detection system can fuse the two detection results to determine the position and moving direction of the emergency vehicle. The ADV can take appropriate actions in response to the position and moving direction of the emergency vehicle.

Abstract: The present invention discloses an analysis method for dynamic contrast-enhanced magnetic resonance image. Firstly, the time-series signal of vascular contrast agent concentration, AIF, of biological individual is obtained from DCE-MRI time-series data. Secondly, perform the nonlinear least sum of square fitting by using the full Shutter-Speed model (SSMfull) and the simplified vascular Shutter-Speed model (SSMvas) on the DCE-MRI time-series signal of each pixel, and the fitting results of DCE-MRI time-series signal are obtained. Thirdly, the corrected Akaike Information Criterion (AICC) score is used to comparing the DCE-MRI time-series signal fitting results to select the optimal model. If the optimal model is SSMfull, distribution maps of five physiological parameters. Ktrans, pb po, kbo, and kio, are produced after fitting; if the optimal model is SSMvas, distribution maps of three physiological parameters, Ktrans, pb, and kbo, are produced after fitting.

Abstract: A therapeutic hybrid microneedle patch mimics the inherent counter-regulatory effects of ?-cells and ?-cells for blood glucose management by dynamically releasing insulin or glucagon contained within the microneedles of the therapeutic hybrid microneedle patch. The two types of microneedles in the therapeutic hybrid microneedle patch share a co-polymerized matrix but comprise different ratios of the key monomers to be ‘dually-responsive’ to both hyper- and hypoglycemic glucose conditions. In a type 1 diabetic mouse model, the therapeutic hybrid microneedle patch effectively controls hyperglycemia while minimizing the occurrence of hypoglycemia in the setting of insulin therapy and simulated delayed meal or insulin overdose. In other embodiments, multiple patches are applied to achieve similar results.
