Magnesium alloys is a lightweight material establishing scope in various fields such as aerospace and automobile. Moreover, magnesium are also considered hydrogen storage materials. In order to understand the machining behaviour of alloy detail research planned. this turning experiments conducted on AZ91 using L9 orthogonal array (OA) experimental design. Technique for Order Preference by Simil...
In the present research, the effects of spot-welding process parameters on the nugget diameter and electrode penetration depth of spot-welded joints were investigated. To achieve this, a spot-welded joint of three-thin sheet low carbon steels (same thicknesses of 0.8 mm) was simulated as an electerical-thermal-mechanical coupling of 3D finite element model. After validating the finite element s...
growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
In this research, a new cost-effective carbon source of medium was provided in terms high-efficiency growth from Arthrospira maxima. Sugarcane molasses used two different modes (alternative and additive) at four concentrations (0, 0.5, 1.0 1.5 gL-1) to determine the effect versus its standard Zarrouk’s (NaHCO3). The experimental results were analyzed by Taguchi L8 method as statistical techniqu...
Dolph-Chebychev arrays are known to exhibit the best compromise between sidelobe level and directivity. However, they place a constraint on the null locations. Any attempt to impose nulls or get them deeper will impact the directivity/sidelobe level trade-off. In this work, null placement in Dolph-Chebychev arrays through element position perturbation is carried out based on Taguchi method whil...
By the grey-based Taguchi methods, this study attempts to analyze the process parameters pertinent to the multiple performance characteristics of linear motion guides and obtain the multiple performance characteristics of the noise level, push force value and horizontal combination precision of the linear motion guide with multiple qualities. Optimal process parameters are determined by using t...
