background: we presumed that the surgeon himself has an impact on the results after coronary artery bypass grafting (cabg) as there is no unique protocol for the discharge of post-operative cardiac patients at our institution. therefore, we examined whether the surgeon himself has an impact on the intensive care unit (icu) stay of isolated cabg patients. methods: we prospectively studied a tota...

the aim of present study was to determine the impact of two different icu management model, open and semi closed, on resources utilization in intensive care unit.retrospective cohort analysis using data from hospital database was applied to compare the effect of icu management model on icu length of stay and bed disposition of 1064 patients admitted to the general icu of imam khomeini hospital ...

Safety and performance are important factors in the design and operation of chemical plants. This paper describes the formulation of a mixed integer nonlinear programming model for the optimization of plant layout with safety considerations. The model considers a quantitative risk analysis to take safety into account, and a bowtie analysis is used to identify possible catastrophic outcomes. The...

This paper primarily presents a comprehensive dynamic layout design model which integrates layout and transportation system design via considering more realistic assumptions, such as taking account of fixed-position departments and distance between departments that endanger each other. In addition, specific criteria such as capacity, cost and reliability of facilities are considered in transpor...

Manually preparing the data for analysis of calculation a pipe network air-cooled turbine blades is inefficient. In this paper, method to adaptively divide blade model and extract flow units proposed. method, topological lines channels calculations were extracted based on simulatedfluid flow. The abstracted fluid area used replace manual interpretation expertsto realize adaptive division unders...

physical (layout) subcircuits (same or different layout system e.g. RF layout) • mechanical subassemblies Within the EU funded ESPRIT project 8369 "CONSOLE", ROHDE & SCHWARZ developed a demonstration software version of a retrieval system for design reuse. • software modules Designing a system in a hierarchical way is done for two main issues: Reducing the time to market by using resources (e.g...
