چکیده
This study investigates the impact of ear and finger curvature on electromagnetic (EM) power absorption resulting heating to quantify potential enhancement induced exposure levels compared commonly used planar tissue models. The analysis is performed at millimeter-wave (mmW) frequencies upcoming for 5G future generations, with a special attention $26 \,\mathrm{GHz}$ notation="LaTeX">$60 . A cylindrical model calculate EM density heat in fingers (radii notation="LaTeX">$\boldsymbol{a\leq }10 \,\mathrm{mm}$ ) ears ( notation="LaTeX">$1 \,\mathrm{mm}\boldsymbol{\leq a\leq }5 ). To compute temperature rise ear, modified account conduction connecting head. Our results show that transverse electric (TE) polarization maximal absorbed remains generally lower than interface (up notation="LaTeX">$-38.2 \,\%$ notation="LaTeX">$-18.7 exceeds this value magnetic (TM) notation="LaTeX">$72.3 notation="LaTeX">$15 always higher model. For notation="LaTeX">$\boldsymbol{a=}1 ), variations steady state reach notation="LaTeX">$93.11 notation="LaTeX">$103.62

the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...
Inferring Body Pose without Tracking Body Parts
A novel approach for estimating articulated body posture and motion from monocular video sequences is proposed. Human pose is defined as the instantaneous two dimensional configuration (i.e.,the projection onto the image plane) of a single articulated body in terms of the position of a predetermined set of joints. First, statistical segmentation of the human bodies from the background is perfor...
متن کاملRobot Stereo-hand Coordination for Grasping Curved Parts
In this paper we present an algorithm to compute set-point (i.e. a position to be reached by the robot) automatically from conic features virtually placed by an operator onto the object. We then use a visual servoing algorithm to guide the gripper to its final position. We have tested this algorithm in trying to open a valve with a 6 degree of freedom robot arm, using only visual information an...

متن کاملPersonnel internal radiation exposure to iodine-125 in a radioiodination laboratory: Exposure levels and trends
ABSTRACT Background: Monitoring internal exposure of individuals handling significant amounts of iodine-125 (I-125) for iodination is of great importance. These individuals are potentially exposed to external contamination, and internal contamination through inhalation, ingestion and intact skin absorption, to I-125. Considering radiological toxicity of this radionuclide its monitoring in the w...
