Computer-generated designs in the sphere are described which have the minimal (or larger) number of runs for a full quadratic response-surface design. In the case of 3 factors, the designs have 10 through 33 runs; for 4 factors, 15 through 28 runs; for 5 factors, 21 through 33 runs; etc. Some of these designs are listed here in full; the others can be obtained from the authors. The designs were...

This article presents the results of a simulation model designed to reduce patient waiting time in the emergency department of a hospital in the United Arab Emirates. The process-oriented simulation model shows how the resources in the hospital are inter-related. The model depicts the hospital operating system and its performance and management issues with regards to allocation of human and mat...

The possibility of gas explosion accidents always exists at offshore facilities of the oil and gas industry. In the design of those structures, the structural safety assessment against explosion loads is necessary to prevent loss of lives or catastrophic failure of structures. One of the essential parts in the structural assessment is to determine design explosion loads. Nowadays, the explosion...

Homogenate extraction method was applied to fast extraction of polysaccharides from loquat leaves. Factors which affected extraction yield were investigated and optimized by response surface methodology (RSM). Results showed that optimum technological conditions were as follows: ratio of liquid to material, 25 ml: 1g; extraction time, 100 s; and pH of extracting solvent, 11. Under optimum condi...

The objective of this research is to compare the cutting parameters of turning operation the work pieces of medium carbon steel (AISI 1045) by finding the longest tool life by Taguchi methods and Response Surface Methodology: RSM. This research is to test the collecting data by Taguchi method. The analyses of the impact among the factors are the depth of cut, cutting speed and feed rate. This r...

Project managers normally are facing with difficulties behind management of project cash flow, which requires distinguished methods and appropriate tools to manage negative cash flows. Cash-Flow-at-Risk (CFaR) model is an efficient approach to predict cash flow trend. In this study, all risk factors affecting project management environment have incorporated to predict an accurate project cash f...
