Retroperitoneoscopic partial nephrectomy (RPN) is one of the standard methods for treating T1-stage renal carcinoma, which has a narrow operational space and a difficult surgical procedure. The aim of this study was to examine the safety and feasibility of renal-rotation techniques in RPN. Between April 2012 and June 2014, the renal-rotation technique in RPN was performed in 22 male and 16 fema...

Over the years, researchers have tried to extend Petri net to model multimedia. The focus of the research flows from the synchronization of multimedia without user interactions, to interactions in distributed environments. The issues in concern are the flexibility and compactness of the model when applied to model a system under change. Most existing models lack the power to model a system unde...

Failure mode and effect analysis (FMEA) is one of the most widely employed pre-evaluation techniques to avoid risks during product design manufacturing phases. Risk priority number (RPN), a risk assessment indicator used in FMEA, field due its simple calculation process, but limitations as an absolute have been pointed out. There has also criticism unstructured nature lack systematicity FMEA pr...

Abstract Safe storage of radioactive materials is based on three universal radiation protection principles. Justification, optimization and dose limits are applicable to the risk assessment, acknowledging hazards in each procedure delivery, usage, disposal materials. Failure Modes Effects Analysis method (FMEA) developed for evaluation common practices. In this work FMEA exploited radiological ...

The quality of midsole products significantly impacts the quality, durability, and comfort users shoe manufactured by ABC company. high percentage average number product defects based on yield data for 12 months is 3.1% which exceeds required company 2%. There are six types in midsole: yellowing, porous, bubbles, broken, over left material trimming. Three from focus improvement Pareto concept, ...

This chapter explores the mathematical and algorithmic properties of two sample-based texture models: random phase noise (RPN) and asymptotic discrete spot noise (ADSN). These models permit to synthesize random phase textures. They arguably derive from linearized versions of two early Julesz texture discrimination theories. The ensuing mathematical analysis shows that, contrarily to some statem...

PURPOSE To determine the feasibility and safety of robotic partial nephrectomy (RPN), we compared the operative outcomes of patients who had undergone RPN with those of patients who had undergone laparoscopic partial nephrectomy (LPN). MATERIALS AND METHODS Between February 2009 and June 2010, 13 patients underwent transperitoneal RPN (group 1) and 14 patients underwent transperitoneal LPN (g...

| In this paper, a new class of higher-order feedforward neural networks, called ridge polynomial networks (RPN) is formulated. The new networks are shown to uniformly approximate any continuous function on a compact set in multidimensional input space with any degree of accuracy. Moreover, these networks have an eecient and regular architecture as compared to ordinary higher-order feedforward ...

background: the reliability and safety of gas refineries are strongly associated with the reliability of other parts of the system. defect and failure in one part of a system can cause total system breakdown or accident. the failure and damage in these equipment such as transformers and boilers results in not only the equipment damage and human injuries but also productivity reduction. the purp...
