Introduction: One approach for the promotion of medical education is to evaluate the university professors’ teaching performance. A commonly-used technique is the student-based evaluation. This study aimed at determining the effective factors in the student-based evaluation of the university teachers’ performance in clinical education. Methods:This is a descriptive cross-sectional survey perfo...
Composite coatings are indispensable for protecting the offshore steel materials serviced in splash zone. But mechanical properties of conventional epoxy resin (EP) poor, which would lead to a short-term lifespan. The carbon fiber (CF) with excellent is an ideal filler reinforce EP coating, thus we chemically grafted Ti3C2Tx nanosheets onto CF via dopamine enhance interface adhesion and compati...
In this paper we investigate decompositions of submodules in modules over a Proufer domain into intersections of quasi-primary and classical quasi-primary submodules. In particular, existence and uniqueness of quasi-primary decompositions in modules over a Proufer domain of finite character are proved. Proufer domain; primary submodule; quasi-primary submodule; classical quasi-primary; decompo...
processing map for hot working of ti-if steel has been developed in the temperature range of 750 to 1100 °cand strain rate of 0.01 to 100 s-1. this map in the austenite region exhibits a single domain with a peak efficiencyof 45% occurring at 1025 °c and strain rate of 0.02 s-1. the domain extends over the temperature range of 1000to 1100 °c and strain rate range of 0.01 to 1 s-1. the true stre...
Motion-JPEG is a common video format for compression of motion images with highquality using JPEG standard for each frame of the video. During transmission through a noisychannel some blocks of data are lost or corrupted, and the quality of decompression frames decreased.In this paper, for reconstruction of these blocks, several temporal-domain, spatial-domain, andfrequency-domain error conceal...
in this paper, an advanced formulation of the spectral finite element method (sfem) is presented and applied in order to carry out site response analysis of 2d topographic structures subjected to vertically propagating incident in-plane waves in time-domain. the accuracy, efficiency and applicability of the formulation are demonstrated by solving some wave scattering examples. a numerical param...
Processing map for hot working of Ti-IF steel has been developed in the temperature range of 750 to 1100 °C and strain rate of 0.01 to 100 s-1. This map in the austenite region exhibits a single domain with a peak efficiency of 45% occurring at 1025 °C and strain rate of 0.02 s-1.

The present paper is aimed at introducing a new algorithm for image encryption using chaotic tent maps and the desired key image. This algorithm consists of two parts, the first of which works in the frequency domain and the second, in the time domain. In the frequency domain, a desired key image is used, and a random number is generated, using the chaotic tent map, in order to change the phase...
Background and Aims : Since government staff is exposed to environmental, socio-economic and occupational stressful factors, their QOL has found much importance. This study aims to determine Boukan’s government staff QOL and its determinant factors. Hence the results of this study can be considered as a pilot and basis for further studies and be used by health policy makers. Materials & Me...
This study derives the discretized adjoint states full waveform inversion (FWI) in both time and frequency domains based on the Lagrange multiplier method. To achieve this, we applied adjoint state inversion on the discretized wave equation in both time domain and frequency domain. Besides, in this article, we introduce reliability tests to show that the inversion is performing as it should be ...
