The performance of an optimized tree-type cylindrical-shaped nanoporous fltering membrane proposed in the former study is analytically investigated for varying operational parameter values. Across the membrane thickness, this membrane has two-leveled tree-structured pores including one trunk pore and the multiple branch pores. The physical properties of the surfaces of ...

* Sponsored by Texas Instruments Inc., Raytheon Inc. and Rocketchips Inc. Abstract-An alternative approach to designing operational amplifiers is presented that focuses on identifying a minimal design parameter space that emphasizes relevant design parameters rather than natural design parameters. It is shown that considerable simplification of some of the key performance parameters can be obta...

this article proposes a direct method for solving three types of integral equations with time delay. by using operational matrix of integration, integral equations can be reduced to a linear lower triangular system which can be directly solved by forward substitution. numerical examples shows that the proposed scheme have a suitable degree of accuracy.

River forecasts have two broad uncertainty classes: errors associated with meteorological forecasts, and those associated with the hydrologic model. We developed a technology (dubbed Absynthe) to address the latter error class in a practical and defensible way. The technique merges the proven, Monte Carlo-based Generalized Likelihood Uncertainty Estimation (GLUE) concept for model parameter ide...

To increase precision and reliability of automatic control systems, we have to take into account of random factors affecting the control system. Thus, operational matrix technique is used for statistical analysis of first order plus time delay system with uniform random parameter. Examples with deterministic and stochastic disturbance are considered to demonstrate the validity of the method. Co...

For the newsvendor inventory control problem with ambiguous demand, Liyanage and Shanthikumar (2005) show that integrating parameter estimation and optimization leads to a better solution compared with the traditional approach. However, how to find the optimal operational statistics is left as an open question in their paper. We derive the optimal operational statistics using a non-informative ...
