multiple input multiple output (mimo) radars are new generation of array radars that employ orthogonal waveforms for their transmit probing signals. despite of several advantages, this strategy results in transmission of uniform power in all angle of array’s viewing field. therefore, possibility of transmit beamforming and achieving coherent processing gain will be lost. many efforts have been ...

The concept of a linear ordered orthogonal array is introduced, and its equivalent geometrical configuration is determined when its strength is 3 and 4. Existence of such geometrical configurations is investigated. They are also useful in the study of (T, M, S)-nets.

Design of Experiment (DOE) is a widely used method for examining experiments especially in industrial production and robust design processes. This set statistical approaches which mathematical models are developed through experimental testing to estimate possible outputs given input values or parameters. The aims determine the main factors that affect results with smallest number studies. In th...

Abstract Aluminum alloy 7075-T651 is a widely used material in the aviation, marine, and automobile sectors. The wide application marks importance of this material’s research manufacturing field. This focuses on optimizing input process parameters turning machining with tungsten carbide insert. are cutting speed, feed, depth cut for output response force, feed radial removal, surface roughness ...

This paper proposes an efficient approach for optimizing the multiple quality characteristics (QCHs) in manufacturing applications on the Taguchi method using the super efficiency technique in data envelopment analysis (DEA). Each experiment in Taguchi’s orthogonal array (OA) is treated as a decision making unit (DMU) with multiple QCHs set as inputs or outputs. DMU’s efficiency is evaluated th...

The paper describes the usage of the fuzzy Mamdani analysis and Taguchi method to optimize the tourism satisfaction in Thailand. The fuzzy reasoning system is applied to pursue the relationships among the options of a tour company in order to be used in Taguchi experiments as the responses. In this research, tourism satisfaction is carried out using L18 Taguchi orthogonal arrays on parameters s...

In his pioneering work on product and process improvement, Taguchi (1986) emphasizes two types of factors that effect product quality: “control factors” are those variables that can be (easily) manipulated by the manufacturer and “noise factors” are those variables that represent either different environmental conditions that affect the performance of a product in the field or (uncontrollable) ...
