Cold rolling process in metal could increase its strength and hardness, but also induces mechanical anisotropy. This is caused by unresolved plastic strain microstructural changes deformation exerted pair of rolls at a relatively low temperature. research aims to provide understandings on anisotropic rate sensitive behaviour St-37 mild steel. The microstructure rolled unrolled plate were observ...

Structural health monitoring (SHM) systems operate online and test different materials using ultrasonic guided waves and piezoelectric smart materials. These systems are permanently installed on the structures and display information on the monitor screen. The user informs the engineers of the existing damage after observing signal loss which appears after damage is caused. In this paper health...

In this study, electroless Ni-B depositions were achieved on the St-37 steel substrates at different NaBH4 concentrations and 950 oC 1 hour. Electroless deposited samples had a cauliflower-like surface texture that makes lubricating naturally as concentration increased, grain size decreases in microstructure. XRD spectra of sample showed partial amorph region together with crystalline region. M...

a survey was carried out in the summer of 1972 in east azerbaijan, northwest iran, to determine the prevalence of cardiovascular disease. ecg tracings were prepared from 198 women and 178 men aged 40-60. only 45% of the tracings were completely normal. q/qs abnormalities were found in 4.7% of tracings, left axis deviation in 4% tall r wave in 37%, st depression in 3.9% of men and 14.1% of women...

Pemilihan arus pengelasan yang mempengaruhi hasil adalah parameter pengelasan, kualitas di pengaruhi oleh energi panas yaitu las. apabila pemilihan las kurang tepat maka tidak akan teratur, melebar dan rata. Penelitian ini bersifat eksperimen suatu cara untuk mencari hubungan sebab akibat antara dua faktor saling berpengaruh. Dengan melakukan pemeriksaan pengujian dengan terhadap sifat-sifat me...

In the present investigation, a novel focusing technique is proposed and demonstrated to enhance strength of synthetic jet array (SJ array). Here, for same geometric operating parameters, SJ achieved by providing non-linear phase delay (∅) between actuators. An open-source software, OpenFOAM, used study influence Strouhal number (St=0.028, 0.086, 0.13) ∅ s (range: 0°−180°) on behavior fixed Rey...
