The Prediction of Forming Limit Diagram of Low Carbon Steel Sheets Using Adaptive Fuzzy Inference System Identifier

The paper deals with devising the combination of fuzzy inference systems (FIS) and neural networks called the adaptive network fuzzy inference system (ANFIS) to determine the forming limit diagram (FLD). In this paper, FLDs are determined experimentally for two grades of low carbon steel sheets using out-of-plane (dome) formability test. The effect of different parameters such as work hardening...

Eccentricity Fault Diagnosis Studying for a Round Rotor Synchronous Machine

The paper presents a mathematical base modeling combined to Modified-Winding -Function-Approach (MWFA) for eccentricity fault detection of a round-rotor synchronous machine. For this aim, a 6-pole machine is considered, and the machine inductances are computed by MWFA in healthy and also under eccentricity fault. A numerical discrete-time method has been proposed to machine modeling in voltage-...

Numerical Modeling and Experimental Study of Probe-Fed Rectangular Dielectric Resonator Antenna (RDRA) Supported by Finite Circular Ground Plane

Dielectric Resonator Antennas (DRAs) have received increased interest in recent years for their potential applications in microwave and millimeter wave communication systems. DRAs are normally used with the support of a ground plane. The radiation and impedance properties therefore depend not only on their physical dimensions and dielectric properties, but also on the size of the ground plane. ...

بررسی عوامل عدم‌قطعیت در عملکرد دینامیکی اسکله به‎روش المان محدود اتفاقی با استفاده از مدل ماتریس تصادفی ویشارت

Exact dynamic analysis of piers due to lack of information about their constituting sub systems, is very complicated. Ordinary finite element methods cannot be used in modeling of complex dynamic systems such as these structures since many uncertainty factors exist which cannot be identified exactly. In addition to physical modeling of a pier structure, existence of uncertainty in dynamic behav...
