[ 1 ] - مقایسه دامنه مؤلفه P300 دانشجویان دارای دانش مفهومی و رویه ای سطح بالا با دانشجویان دارای دانش مفهومی و رویه ای سطح پایین در حل مسائل انتقال بین بازنمایی نموداری و جبری تابع
مقدمه: در این مقاله به کمک پتانسیل‌های وابسته به رویداد (ERPs)، به بررسی تفاوت‌های الکتروفیزیولوژی دو گروه از دانشجویان، هنگام حل مسائل انتقال بین بازنمایی نموداری و جبری تابع، پرداخته می‌شود. روش: این پژوهش از نوع کمی و به روش نیمه آزمایشی می‌باشد. جامعه آماری شامل 177 نفر از دانشجویان سال اول رشته‌های مهندسی دانشگاه فردوسی مشهد هستند که به کمک یک آزمون ریاضی محقق ساخته به دو گروه دانش مفهومی ...
[ 2 ] - Dynamic Modeling of the Electromyographic and Masticatory Force Relation Through Adaptive Neuro-Fuzzy Inference System Principal Dynamic Mode Analysis
Introduction: Researchers have employed surface electromyography (EMG) to study the human masticatory system and the relationship between the activity of masticatory muscles and the mechanical features of mastication. This relationship has several applications in food texture analysis, control of prosthetic limbs, rehabilitation, and teleoperated robots. Materials and Methods: In this paper, w...
[ 3 ] - A Hybrid Neural Network Approach for Kinematic Modeling of a Novel 6-UPS Parallel Human-Like Mastication Robot
Introduction we aimed to introduce a 6-universal-prismatic-spherical (UPS) parallel mechanism for the human jaw motion and theoretically evaluate its kinematic problem. We proposed a strategy to provide a fast and accurate solution to the kinematic problem. The proposed strategy could accelerate the process of solution-finding for the direct kinematic problem by reducing the number of required ...
[ 4 ] - Studying the Mechanical Behavior of Tissue in the Generation of Pressure Sores using Simulation and a Guinea Pig Experimental Model
Introduction: Pressure sores refer to lesions that are produced while a constant pressure causes necrotic tissue to grow. The need for a better comprehension of the process has led researchers to artificial generation of pressure sores. Modeling the mechanical behavior of tissue will provide a better understanding of this process as well as a more suitable selection ...
[ 5 ] - بررسی مقایسه فعالیت الکترومیوگرافی عضلات ساق پا در زنان ورزشکار با و بدون درد ساق پا
Abstract Objective: One of the most common injuries caused by over use is Shin splint or leg pain that occurs in the anterior lower leg during running. The aim of this study was to evaluate the Electromyograph of the leg muscles and also the associated of that with shin splint. Materials & Methods : from students of Physical Education majors , 17 people with Shin splint with average height an...
[ 6 ] - استفاده از ترکیب الگوریتم ژنتیک و شبکه های عصبی مصنوعی برای پیش بینی نیروی گاز گرفتن از روی سیگنال الکترومایوگرام
Human mastication is a common rhythmic behavior and a complex biomechanical process which is hard to reproduce. Today, investigating the relation between electrical activity of muscles and force signals is of high importance in many applications including gait analysis, orthopedics, rehabilitation, ergonomic design, haptic technology, tele-presence surgery and human-machine interaction. Surface...
[ 7 ] - بررسی الکتروانسفالوگرام شبکه موثر مغز انسان در حین گوش دادن به موسیقی به منظور تشخیص احساسات
In the current research brain effective networks related to happy and sad emotions are studied during listening to music. Connectivity patterns among different EEG channels were extracted using multivariate autoregressive modeling and partial directed coherence while participants listened to musical excerpts. Both classical and Iranian musical selections were used as stimulus. Participants’ se...
