We present supporting material for the manuscript ”Imaging widespread seismicity at mid-lower crustal depths beneath Long Beach, CA, with a dense seismic array: Evidence for a depth-dependent earthquake size distribution”. The material contains three figures. The purpose of the figures is to illustrate the advantages of downward-continuing the data prior to back-projection, and to provide detai...
Basic left-handed transmission line (LH-TL) characteristics made on PCB is an important future issue for the application of the EMC field. In this paper, possibility of a LHTL characteristic made by a folded-stepped impedance resonator (F-SIR) type is investigated experimentally and theoretically as a first time. The calculations by FDTD and/or FEM (HFSS) show the usability of the LH-TL. The ex...
We compute the corrections, using the tunneling formalisim based on a quantum WKB approach, to the Hawking temperature and Bekenstein-Hawking entropy for the Schwarzschild black hole. The results are related to the trace anomaly and are shown to be exactly equivalent to results inferred from Hawking’s original calculation based on path integrals using zeta function regularization. Finally, expl...
This paper describes the application of machine vision technology to prevention of collision accidents with heavy equipment such as hydraulic excavators and cranes. The images of the back side of heavy equipment with cameras which can take a picture with 180 degree shooting angle were captured and the worker was detected by developed color image processing algorism. A laser range finder and an ...

For comparison we also include calculated approximate values for the second moments of the el...
In this paper we describe a new high speed method for the calculation of UHF propagation over irregular terrain which is considered to be a homogeneous dielectric. The method, given that it is rigorous and includes both forward and back scattering, is very fast. The antenna pattern, tilt etc. may be specified arbitrarily. As expected, results compare very well with measurements in the case when...
Studies have shown that number line estimation is important for learning. However, it is yet unclear if number line estimation predicts different mathematical skills in different grades after controlling for age, non-verbal cognitive ability, attention, and working memory. The purpose of this study was to examine the role of number line estimation on two mathematical skills (calculation fluency...
In vivo dosimetry seems an appropriate method for quality assurance in radiotherapy with CO-60, which can be considered as a routine program in radiotherapy centers. In this study, entrance and exit dose in tangential fields were measured in phantom for 30 breast cancer patients by using TLD in radiotherapy section of Imam Khomeini Hospital. TLD crystals were calibrated against SSDL (Secondary...
The aim of this study is to investigate the effect of boundary conditions on the accuracy and stability of the numerical solution of fluid flows in the context of single relaxation time Lattice Boltzmann method (SRT-LBM). The fluid flows are simulated using regularized, no-slip, Zou-He and bounce back boundary conditions for straight surfaces in a lid driven cavity and the two-dimensional flow ...
In this paper, the optimal design of a non-slotted AF (Axial Flux) motor is presented using sizing equations, IPSO (Improve Particle Swarm Optimization) algorithm and Finite Element software. IPSO optimization method reduces the evaluation time of the motor design, because of parallel evaluation. This reduction of time is relevant to number of the CPUs. The optimization objective is to achieve ...
