In this paper, reliability block diagram of a sounding rocket separation system is determined and also, FMEA analysis of its spring mechanism is performed. This system is based on the flexible linear shape charge crosssection system and a spring mechanism to accelerate separation. In this investigation, reliability block diagram of the separation system include mechanical and electrical mechani...

Failure modes and effects analysis (FMEA) has been used to identify the critical risk events and predict a system failure to avoid or reduce the potential failure modes and their effect on operations. The risk priority number (RPN) is the classical method to evaluate the risk of failure in conventional FMEA. RPN, which ranges from 1 to 1000, is a mathematical product of three parameters—severit...

BACKGROUND AND PURPOSE Robot-assisted partial nephrectomy (RPN) has emerged as a viable approach to minimally invasive surgery for small renal tumors. There are few reports of RPN for tumors >4 cm. Our objective was to evaluate outcomes of RPN for tumors >4 cm compared with RPN for tumors ≤ 4 cm in a large multi-institutional study. PATIENTS AND METHODS We reviewed data for 445 consecutive pa...

Nephron-sparing surgery is currently considered the gold standard treatment for T1 renal tumors. As laparoscopic partial nephrectomy (LPN) represents a technically challenging procedure, robotic surgery has been increasingly used during the last few years in the field of nephron-sparing surgery. The aim of this review is to analyze the techniques and outcomes of robotic partial nephrectomy (RPN...
