Diagnosis of Brain Tumor Position in Magnetic Resonance Images by Combining Bounding Box Algorithms, Artificial Bee Colonies and Grow Cut

Mahdi Shafiof; Neda Behzadfar

Volume 11, Issue 01 , March 2022, Pages 1-12

Abstract
  Tumor detection and isolation in magnetic resonance imaging (MRI) is a significant consideration, but when done manually by people, it is very time consuming and may not be accurate. Also, the appearance of the tumor tissue varies from patient to patient, and there are similarities between the tumor ...  Read More

Robust H_2 / H_∞ Multi Objective Controller Design with Takagi-Sugeno Fuzzy Model for a Mobile Two-Wheeled Inverted Pendulum

Davood Allahverdy; Ahmad Fakharian

Volume 11, Issue 01 , March 2022, Pages 13-20

Abstract
  In this study, a robust H_2/H_∞ multi-objective state-feedback controller and tracking design are presented for a mobile two-wheeled inverted pendulum (MTWIP). The proposed control has to track the desired angular velocity while keeping the mobile two-wheeled inverted pendulum balanced. First, ...  Read More

Dynamic Behavior Improvement of Control System in Inverter-Based Island Microgrid by Adding a Mixed Virtual Impedance Loop to Voltage Control Loop

Saeid Farhang; Ghazanfar Shahgholian; Bahador Fani

Volume 11, Issue 01 , March 2022, Pages 27-34

Abstract
  A common method for controlling a group of parallel converters in decentralized control strategy structure in an island microgrid, the use is the droop-down characteristics of frequency ω-P and voltage E-Q. However, the problem with using this method is that the reactive power is not properly distributed ...  Read More

A Smart Noise-Coupling Technique for low power DT-Σ∆ Modulators

Habibeh Fakhraie; Tohid Moosazadeh; Reza Sabbaghi-nadooshan; Alireza Hassanzadeh

Volume 11, Issue 01 , March 2022, Pages 35-40

Abstract
  In this paper, a new method for extending and relaxing the noise-coupling (NC) technique is proposed to enhance the noise-shaping order without adding the number of integrators. The noise-shaping order of the introduced ∑∆ modulator whit applying a second-order noise-coupling technique is enhanced ...  Read More

Decentralized Robust Adaptive Control Based On Dynamic Programming for SVC Complement Controller Design

Ameneh Barani; Majid Moazzami; Mohammad Amin Honarvar; S.Mohammadali Zanjani

Volume 11, Issue 01 , March 2022, Pages 41-48

Abstract
  One of the issues of reliable performance in the power grid is the existence of electromechanical oscillations between interconnected generators. The number of generators participating in each electromechanical oscillation mode and the frequency oscillation depends on the structure and function of the ...  Read More

A Quaternary Representative for Serial Transceiver Using Pulse Slope Encoding

Mosslem Amiri

Volume 11, Issue 01 , March 2022, Pages 47-54

Abstract
  In this paper, a new scheme for serial communication is proposed. In this method, in addition to the pulse states (high and low), either of negative slope or positive slope of the pulse (saw-tooth waveform) is employed as a representative for another digit. Using pulse slope as a representative for a ...  Read More
