this study reports the fabrication of n-tio2/p-si hetrojunction by deposition of tio2nanowires on p-si substrate. the effect of system pressure and the current-voltage (i-v) characteristics of n-tio2/p-si hetrojunction were studied. the morphology of the samples was investigated by field emission scanning electron microscopy (fesem) which confirms formation of tio2 nanowires that their diameter...

introduction: transtibial amputation is the most common amputation in lower limbs. volume loss of residual limb occurs during daily use of prostheses, which results in pistoning between residual limb and prosthetic socket. the goal of this study was to design and fabricate a pneumatic suspension system in transtibial supracondylar prostheses and to evaluate its effect on residual limb pistoning...

a watching system in a graph $g=(v, e)$ is a set $w={omega_{1}, omega_{2}, cdots, omega_{k}}$, where $omega_{i}=(v_{i}, z_{i}), v_{i}in v$ and $z_{i}$ is a subset of closed neighborhood of $v_{i}$ such that the sets $l_{w}(v)={omega_{i}: vin omega_{i}}$ are non-empty and distinct, for any $vin v$. in this paper, we study the watching systems of line graph $k_{n}$ which is called triangular grap...
