The fuzzy neuron hybrid control method is proposed for mold level control of the continuous steel casting in this paper. The dynamic characteristics of the continuous steel casting process is described. To the plant with big uncertainties and grave nonlinearities, the fuzzy neuron hybrid control system is set up and the new model-free controller is designed. In this control system, the fuzzy ne...

A control valve is the most heavy and expensive device in pneumatic driving system for a soft mechanism. To realize compact inexpensive system, size, weight, cost of must be reduced. In previous study, small-sized servo that can flow rate using diaphragm gate mechanism, driven by low-cost RC motor, was proposed tested. However, mechanism should adjust relative positions rotating disk to achieve...

This research aims at presenting a consolidated model of data envelopment analysis (DEA) technique and value engineering to select the best manufacturing methods for gate valve covers and ranking the methods using TOPSIS.To do so, efficiency evaluation indices were selected based on the value engineering approach and different manufacturing methods were evaluated using DEA technique.Finally, ef...

Ketersedian peralatan pembelajaran laboratorium dalam menghitung nilai head loss, khususnya untuk menunjukkan coefficient loss pada valve, dibuat prototipe sistem perpipaan dengan menggunakan valve diamati nya. Dalam realitanya tidak semua persoalan aliran dapat diselesaikan persamaan bernoulli karena beberapa terdapat kerugian energi, juga ada mekanik, sehingga Bernoulli. Karakteristik yang me...

Figure 1: Preoperative computer tomography scan showing adequate dimensions of the iliofemoral vessels and acceptable tortuosity for a transfemoral valve implantation (A). Deployment of the first 26-mm Sapien valve resulting in a paravalvular leakage >2+ (B). Implantation of a second valve to (asterisk) to cover the leakage, as the position of the first valve (hash) was considered to be too hig...
