Abstract. This paper is focused on the design, implementation and testing of an active reflector, to be used support deformation monitoring studies based Synthetic Aperture Radar interferometry. The device designed work in C-band with Sentinel-1 data, operating at 5.405 GHz ± 50 MHz. A brief description reflector provided. It consists two antennas amplifying section. has been tested different e...
ین پایان نامه با هدف سنتز و شناسایی چهار نوع از نانو ذرات آغاز می شود. نانو ذرات آلوم اکسان از واکنش بوهمیت و کربوکسیلیک اسید مربوطه حاصل شدند. هدف از سنتز این نوع نانو ذرات ساخت غشاهای عامل دار شده با خاصیت آب دوستی و انتخاب پذیری جهت جداسازی روغن از مخلوط های آب و روغن، می باشد. tg-dta، ftir، sem، tem، uv/vis spectrophotometer، digital camera،contact angle measurement goniometer، ultrasonic b...
Introduction: In the universities and academic institutes, most of the research activities are performed in departments and research centers, which are evaluated by measurement of indices such as number of academics and students, number of publications and patents, citation analysis, journals in which their reports have been published, the amount of grants etc. Methods: Academic department is c...
objectives: the purpose of this study was to investigate the relation of personality traits with depression in active and non – active elderly women in tehran city. methods & materials: the present research is descriptive–correlation. for this purpose, 188 elderly women (94 active and 94 non - active elders) in the age range of 63-82 in tehran city availably selected as statistical sample. meas...
Background: The aim of this research was to determine the Mn superoxide dismutase (Mn SOD) gene expression and the impact of oxidant and inflammatory markers on Mn SOD gene expression in active men and women. Methods: This research was a semi-experimental with repetitious measurement, and 24 active men (12) and women (12) (21-23 years) voluntarily participated in this research after ...
CoMPACT monitor that we have proposed is new technique to measure per-flow quality of service (QoS). CoMPACT monitor provide scalable measurement of one-way delay distribution by the combination of active and passive measurement. Recently, a new probing method for improving the accuracy of simple active measurement have been proposed. In this paper, we adopt the new probing method as active mea...
Allocation of measurement devices is a necessity of distribution system which is an application of state estimation. In this paper, the problem of active and reactive measurement devices is modeling using a multi-objective method. The objectives of the problem are to minimize the use of measurement devices, increase in state estimation output, improve the state estimation quality and reduce cos...
