Abstract: The application relates to a method for developing the agitation system of a scale-up polymerization vessel. A simulated prediction model is obtained by use of a small polymerization vessel and by integrating Taguchi experimental design method with artificial intelligence (AI) neural network. Accordingly, vessel parameters for the agitation system of a scale-up polymerization vessel can be rapidly and accurately predicted based on simulation qualities thereof, further facilitating a construction of the agitation system of a scale-up polymerization vessel.

Abstract: A system to display automatically organized images coordinating with pace of background music is disclosed. Users only need to give images and a music clip, and the system will automatically generate a presentation that combines visual and aural effects to display the organized images synchronously accompanying the music. Multiple images that have similar characteristics are well arranged and displayed at the same frame to emphasize the atmosphere of viewing experience. In addition, collaborative presentation of images that is synchronous to music even improves the enjoyment of image browsing.

Abstract: A ratchet based transmission mechanism mounted in a wheel for a child bicycle is disclosed. In a propelling of the bicycle a pawl is pushed against a tooth, a ratchet disk rotates as both pawl blocks and a transmission disk rotate, and the ratchet disk is secured in a bore of the wheel. When a rotation speed of the wheels is faster than a rotation speed of pedals, the pawl blocks will be pushed inward by the teeth for disengaging the ratchet disk from the transmission disk for stopping the pedals while maintaining the rotation of the wheels. This can prevent a skid from occurring while the bicycle is running on a downhill road or accelerating.
