Cross-sectional echocardiography is a new noninvasive technique for imaging the heart. We developed a method for using mechanical cross-sectional echocardiograms (sector scans) to determine left ventricular volumes and ejection fraction. Using left ventricular cineangiography as a standard, sector scan ejection fraction correlated better (r = 0.93) than M-mode echocardiography by any of three e...

in this paper, an optimal adaptive fuzzy integral sliding mode control is presented to control the robot manipulator position tracking in the presence of uncertainties and permanent magnet dc motor. in the proposed control, sliding surface of the sliding mode control is defined according to the information of position tracking error, derivatives, and error integral. in order to estimate bounds ...

This paper discusses some mat hematical issues related to empirical mode decomposition (EMD). A B-spline EMD algorithm is introduced and developed for the convenience of mathematical studies. The numerical analysis using both simulated and practical signals and application examples from vibration analysis indicate that the B-spline algorithm has a comparable performance to that of the original ...

The MADS domain protein AGL15 (AGAMOUS-Like 15) has been found to preferentially accumulate in angiosperm tissues derived from double fertilization (i.e. the embryo, suspensor, and endosperm) and in apomictic, somatic, and microspore embryos. Localization to the nuclei supports a role in gene regulation during this phase of the life cycle. To test whether AGL15 is involved in the promotion and ...

Teachers should be received specialized training, have higher education workers of professional quality. In order to develop the high quality teacher, teacher training curriculum should focus on professional skills. Our school has to strengthen the professional skills of teachers as a breakthrough in curriculum mode innovation, by enhancing practice teaching in the curriculum, strengthen the et...

We use a combination of symmetry analysis, phenomenological modeling, and first-principles density functional theory to explore the interplay between magnetic ground state detailed atomic structure in hexagonal rare-earth manganites. find that ordering is sensitive breathing mode distortion Mn O ions $ab$ plane, which described by ${\mathrm{K}}_{1}$ high-symmetry structure. Our calculations int...

the present article employs sociological, socio-psychological and anthropological theories design a theoretical framework and model with due regard to theoretical viewpoints and experimental resources and proposes hypotheses on the basis of them. the integrative research method includes a survey and historical study. the population includes 404 teachers related to 6 tribal groups: curd, fars, t...

National identity is the most pervasive level of identity among all social systems. In compare with other type of common identity, the national identity will affect on different aspects of life in every social system. So, this study attempts to examine Yazd young's attitude toward national identity and its effective factors. The sample size of this survey consists of 378 young (18-30 ages) whic...

This study examined the role of team identity on job satisfaction and job performance regarding the mediating role of the organizational identity. This paper is a correlation type using descriptive methods with applied goals. Our statistical population included all 420 male and female staffs of the telecommunication department in Eastern Azerbaijan province, Iran in 2014.Using stratified random...

background: each group or profession has its own discourse. discourses create identity, support institutions and reproduce power relationships. professional identity of iranian nurses, which has recently had the opportunity to represent itself in social arena, needs investigation. this study aimed to make internal aspect of this identity clear. materials and methods: this study was conducted by...
