Mobile Ad hoc Networks (MANETs) are becoming popular technologies because they offer flexibility in setting up anytime and anywhere, provide communication support on the go. This requires use of Transmission Control Protocol (TCP) which is not originally designed for MANET environments; therefore, it raises serious performance issues. To overcome deficiency original TCP, several modifications h...
Over two decades, a problem of location dependent has been focused for improving the communication Bandwidth-Power Efficiency of homogeneous networks. The efficiencies of communication links are weakened by the Hidden Terminal Problem. Thus we propose a Fine – Tune Strategy for analyzing the On-Off communication region. We were observed that the proposed technique had been able to track and mo...
Since tubes are widely used for different industrial applications, processing of tubes by the Severe Plastic Deformation (SPD) method has been the target of different attempts. Among these attempts, development of SPD processes for tubes based on Equal Channel Angular Pressing (ECAP) has been more successful. As an illustration, Tube Channel Pressing (TCP) has been presented as an attractive SP...
In order to investigate P acquisition efficiency (PACE) and P utilization efficiency (PUTE) of the corn in the presence of phosphate-solubilizing microorganisms (PSMs), a factorial experiment was carried out in a completely randomized design in the greenhouse. The factors were including P sources (tricalcium phosphate (TCP) and rock phosphate (RP)) and microbial inoculation (control, soluble P ...
Since tubes have numerous industrial applications, different attempts are focused on the severe plastic deformation processes of tubes. As an illustration, tube channel pressing (TCP) is an attractive process for this purpose since it can be used for processing of different sizes of tubes. However, more attempts are needed to improve the outcomes of TCP. For example, imposing of a greater strai...
Introduction: The high local control rates observed in patients with breast cancer who had been treated by modified radical mastectomy, chemotherapy and chest-wall irradiation using 120 kV X-rays (50 Gy in 25 fractions) motivated us to investigate their observed tumor control probability (TCP) and test a well-established radiobiological TCP model against our data. Mat...
فسفر یکی از عناصر ضروری و دومین عنصر محدود کننده رشد گیاهان می¬باشد. در نتیجه واکنش-های شیمیایی قسمت عمده¬ای از فسفر تثبیت و به شکل¬های غیرمحلول و غیرقابل دسترس تبدیل می¬شود. باکتری¬های حل¬کننده¬فسفات می¬توانند فسفر خاک را به فرم قابل دسترس تبدیل و رشد و عناصر غذایی گیاه را افزایش دهند. هدف این تحقیق جداسازی و خالص¬سازی باکتری¬های حل-کننده¬فسفر از ریزوسفر ذرت و سویا و ارزیابی اثر جدایه¬های منتخ...
شبکه هوشمند برق عبارتست از یک شبکه ارتباط داده که با شبکه فعلی برق ادغام شده و می تواند داده های بدست آمده از سیستم های انتقال، توزیع و مصرف را جمع آوری و تحلیل نماید. ارتباطات در چنین شبکه ای، نقش حیاتی ایفا می کند و پروتکل های مورد استفاده در این ارتباطات، تاثیر مستقیم بر روی کارایی و عملکرد شبکه هوشمند برق خواهند داشت. لذا انتخاب پروتکل ارتباطی مناسب و بهبود آن برای استفاده در چنین محیط هایی...
