Fig.1 Measurement system In this paper, the three-dimensional surface shape measurement system with the temperature information is introduced. The measurement is established using a three-dimensional surface measurement system and a thermography. The measurement system is composed of CCD camera, a laser and thermography. The laser is projected to the object and the laser streak image appeared o...
Two pilot studies investigated potential sources of error in static human body surface measurement for conventional anthropometry methods and three-dimensional electromechanical methods under different experimental conditions. In the first pilot study, two anthropometrists measured Humeral breadth, Radiale-Stylion length and Wrist breadth of a cadaveric arm repeatedly in nearly nude and lightly...
The present paper tries to describe the advantage and improvement of a numerical model when predicting government processes on Flow Rivers. With regard to the important effect of the flow velocity and shear stress forces on river bank erosion, we apply a Two-Dimensional numerical model, named CCHE2D, to simulate river flow pattern at a meandering river Khoshk-e-Rud River of Farsan, 30 Km west o...
This paper aims to develop three-dimensional measurement method based on digital holographic microscopy (DHM) to investigate the droplet-based microfluidic phenomena. The advantage of DHM is the direct measurement method for the three-dimensional measurement target with single camera based on analysis of phase information of holographic images. Furthermore, we tried to measure two important inf...
The measurement of large forces and the presence of errors due to dimensional coupling are significant challenges for multi-dimensional force sensors. To address these challenges, this paper proposes an over-constrained six-dimensional force sensor based on a parallel mechanism of steel ball structures as a measurement module. The steel ball structure can be subject to rolling friction instead ...
This paper proposes and verifies a SAR measurement procedure for a multi-antenna transmitter that requires the measurement of two-dimensional electric field distributions for the number of antennas and the calculation for obtaining the three-dimensional SAR distributions for arbitrary weighting coefficients of the antennas prior to determining the average SAR. The proposed procedure is verified...
