introduction: the use of multiple cameras for motion analysis and single joint motion is very difficult and needs high technology in laboratory conditions. detection of single joint motion in kinesthesia and analysis of its changes can be done by one camera at one direction. in this study, we present the validity and reliability of a new prototype simulator system used for motion analysis appli...

H. Nahvi and M. Sobhani,

In this paper, dynamic and stability analysis of a flexible cam-follower system is investigated. Equation of motion is derived considering flexibility of the follower and camshaft. Viscous and Coulomb frictions are considered in the rocker arm pivot. The normalized equation of motion of the system is a 2nd- order differential equation with periodic coefficients.&#10Floquet theory is employed to...

" استاپ موشن" (stop motion) یا انیمیشن ایست – حرکتی یکی از تکنیک های ساخت انیمیشن که در آن با استفاده از فیلمبرداری فریم به فریم اشیاء فیزیکی را به حرکت در می آورند و از پشت سر هم قراردادن تصاویر این حرکت های فریم به فریم، تصور حرکت القا می شود. "موشن گرافیک" (motion graphic) نیز یکی دیگر از تکنیک های ساخت انیمیشن است. این تکنیک با استفاده از تکنولوژی ویدئو و با ایجاد توهم حرکت یا تغییر در ظاهر...

In the context of industrial engineering, the predetermined time systems (PTS) play an important role in workplaces because inefficiencies are found in assembly processes that require manual manipulations. In this study, an approach is proposed with the aim to analyze time and motions in a manual process using a capture motion system embedded to a virtual environment. Capture motion system trac...

In this paper, the main goal is to reduce the heave motion between a surface effect ship (SES) and a wind turbine in order to safely transfer equipment and person to SES. For this purpose, an LQR control system is designed to damp the vertical motion of the surface effect ship in critical sea states including high-frequency and high amplitude regular waves as well as high frequency irregular wa...
