In this study, the effect of cold rolling process on the microstructure and texture evolution in 1wt. % Si non-oriented electrical steel was investigated. For this purpose, all samples were processed through single-stage hot rolling at 1100 ° C and two-stage cold rolling (cross rolling and unidirectional rolling) with intermediate annealing at 650 °C for 35 seconds. Finally, all of them were fu...
The reuse of already deployed single mode fiber is seen as one the key enablers for cost-efficient capacity upgrades optical transmission systems. Unlocking benefits other bands, to further increase capacity, can enable networks adapt highly dynamic traffic patterns. In here and now, C-band based coherent receiver frontends would be a cost-effective solution support bandwidth division multiplex...
In this paper, triple band rectangular microstrip antenna with two vertical rhombus shaped slot (TBRMA2VRS) is designed and developed for S and C band frequency applications. The triple bands are obtained by etching two rhombus slots on the patch surface. The impedance bandwidth of secondary band is enhanced from 2.06% to8.54% by replacing the two rhombus slots. The radiation patterns measured ...
A wideband antenna with dual band characteristic at 5.33/14.3 GHz resonating frequencies for wireless applications is presented. The strategy of the design to introduce multiband in band. Band width increases by embedding annular ring on radiating patch and four bands are achieved introducing coupling gap between patches. Surface current distribution analyzed different understanding radiation m...
حلقه های قفل شده فاز تمام دیجیتال یکی از مباحث مهم در دنیای امروز الکترونیک هستند. حلقه قفل فازهای (pll ) که به وسیله روشهای آنالوگ طراحی می شدند نسبت به تغییرات دما و ولتاژ و پروسس حساس بودند. این امر موجب سختی طراحی و نیازمندی به طراحی مجدد در تکنولوژی های جدید می شود. این در حالی است که با استفاده از حلقه های قفل فاز تمام دیجیتال این مشکلات برطرف میشوند. حلقه های قفل فاز تمام دیجیتال (adpll...
The stable configurations, electronic structure and magnetic properties of B16N16, B8C24, Al and P inserted (BC3)8 was studied by performing density functional theory (DFT) calculations of the NMR parameters. The results indicate that B8C24 has semiconductivity property and be effectively modified by inserti...
Introduction: Atherogenic index of plasma (AIP) can be considered as an appropriate criterion predicting coronary heart disease. This study aimed to investigate the effect of eight weeks of resistance band training along with green coffee supplementation on lipid profiles and atherogenic index of plasma in obese women. Methods: 88 obese women (BMI>30) at the age range of 30-50 years were selec...
