[ 1 ] - A Sub-Optimal Look-Up Table Based on Fuzzy System to Enhance the Reliability of Coriolis Mass Flow Meter
Coriolis mass flow meters are one of the most accurate tools to measure the mass flow in the industry. However, two-phase mode (gas-liquid) may cause severe operating difficulties as well as decreasing certitude in measurement. This paper presents a method based on fuzzy systems to correct the error and improve the reliability of these sensors in the presence of two-phase model fluid. Definite ...
[ 2 ] - A New Model of Car Following Behavior Based on Lane Change Effects Using Anticipation and Evaluation Idea
This paper aims to investigate a new and intricate behavior of immediate follower during the lane change of leader vehicle. Accordingly, the mentioned situation is a transient state in car following behavior during which the follower vehicle considerably deviates from conventional car following models for a limited time, which is a complex state including lateral and longitudinal movement simul...
[ 3 ] - A magnetorheological fluid damper for robust vibration control of flexible rotor-bearing systems: A comparison between sliding mode and fuzzy approaches
Squeeze Film Dampers (SFD) are commonly used for passive vibration control of rotor-bearing systems. The Magnetorheological (MR) and Electrorheological (ER) fluids in SFDs give a varying damping characteristic to the bearing that can provide active control schemes for the rotor-bearing system. A common way to model an MR bearing is implementing the Bingham plastic model. Adding this model to th...
[ 4 ] - طراحی و ساخت کالیبراتور تراز الکترونیکی دقیق و تحلیل عدم‌قطعیت در فرآیند کالیبراسیون
تراز الکترونیکی به عنوان ابزار تنظیم زوایای دقیق در تجهیزات پیشرفته کاربرد دارند. دقت و صحت عملکرد تراز باید با استفاده از وسایل کالیبراسیون ظریف و حساس مورد ارزیابی قرار گیرد. در این پژوهش به منظور کالیبراسیون و ارزیابی دقت یک تراز الکترونیکی دو محوره بسیار دقیق، یک ابزار کالیبراسیون با قابلیت موقعیت‌‌دهی و تفکیک‌پذیری یک میکرون طراحی و ساخته شده است. سپس با استفاده از آن، به بررسی روابط خطی و...
[ 5 ] - On the Corotational Beam Element Formulation in Large Deformation Analysis
This paper sheds more light on the co-rotational element formulation for beams with uniform cross-section. The co-rotational elements are commonly used in problems in which a structure undergoes a large deformation. In this study, the foregoing element obeys the Euler-Bernoulli beam assumptions. Unlike the formulations presented in the literature, in this paper, a number of local nodal coordina...
