This paper considers the design of robust`1 estimators based on multiplier theory (which is intimately related to the mixed structured singular value). Speciically, the Popov-Tsypkin multiplier is used to develop an upper bound on an`1 cost function over an uncertainty set. The robust`1 estimation problem is formulated as a parameter optimization problem in which the upper bound is minimized su...

The objective of the Taguchi parameter design is to improve the performance of a product or a process by determining the levels of its design parameters such that the performance characteristic is robust against various causes of variation. Parameter design problems are broadly classified into static and dynamic ones. Static problems are further classified into the-nominal-thebest, the-larger-t...

Computerized adaptive testing is becoming increasingly popular due to advancement of modern computer technology. It differs from the conventional standardized testing in that the selection of test items is tailored to individual examinee’s ability level. Arising from this selection strategy is a nonlinear sequential design problem. We study, in this paper, the sequential design problem in the c...

This paper involves the multi-objective optimization of process parameters of AlSi10Mg/9 wt% alumina/3 wt% graphite in Electrical Discharge Machining for obtaining minimum surface roughness, minimum tool wear rate and maximum material removal rate. The important machining parameters were selected as peak current, flushing pressure and pulse-on time. Experiments were conducted by selecting diffe...

Project preemption allows resources flow passively from one project or task to another. Due to high-cost and high-risk characteristics of software development, project preemption might have a significant impact on the ultimate completion time of a software project. This article examines the feasibility of the Taguchi’s parameter design to achieve robust resource assignment for multiple software...

the inverse problem of identifying an unknown source control param- eter in a semilinear parabolic equation under an integral overdetermina- tion condition is considered. the series pattern solution of the proposed problem is obtained by using the weighted homotopy analysis method (wham). a description of the method for solving the problem and nding the unknown parameter is derived. finally, tw...
