Optimum energy consumption and prevention of energy losses are important issues in various fields including agricultural engineering. Mower is one of the agricultural machineries that can waste too much energy if does not function properly. In this study, the performance of a single disc rotary mower was studied and optimized by measurement of cutting quality of the stem cross section (cutting ...

Board-level package is a complicated multi-components structure. It can be simulated by an equivalent Finite Element Analysis (FEA) model of the board-level package, in which detailed layer structure of the Print Circuit Board (PCB), signal wires and through-holes were ignored. For this purpose, it is necessary to obtain the equivalent material properties of the board-level package. In this wor...

Abstract—A number of studies have been conducted recently to investigate the influence of randomly oriented fibers on some engineering properties of cohesive and cohesionless soils. However, few studies have been carried out on freezing-thawing behavior of fine-grained soils modified with discrete fiber inclusions and additive materials. This experimental study was performed to investigate the ...

OBJECTIVE The objective of the research was to formulate and evaluate sumatriptan succinate-loaded chitosan nanoparticles for migraine therapy in order to improve its therapeutic effect and reduce dosing frequency. MATERIAL AND METHODS The Taguchi method design of experiments (L9 orthogonal array) was applied to obtain the optimized formulation. The sumatriptan succinate-loaded chitosan nanop...

A Taguchi robust design method with an L₉ orthogonal array was implemented to optimize experimental conditions for the biosynthesis of triethanolamine (TEA)-based esterquat cationic surfactants using an enzymatic reaction method. The esterification reaction conversion% was considered as the response. Enzyme amount, reaction time, reaction temperature and molar ratio of substrates, [oleic acid: ...

The non-homogeneous and anisotropic nature of composites poses challenges during machining, requiring the use specialized cutting tools. GFRP materials were selected for their excellent elasticity, corrosion resistance, high strength, making them ideal applications in aerospace automotive industries. In this work, surface quality UD-GFRP composite bars CNC machining diverse conditions (dry, wet...

Shielded Metal Arc Welding (SMAW), an arc welding process, is widely used in applications. In practice, SMAW applied to the process on hollow square pipe. Performance expected from this tensile strength of weld joint. The influenced by parameters which have possibility for optimization become ‘robust’. Robust a design less sensitive effect uncertain quantities or noise factors. Taguchi method m...

Aluminum matrix composites are widely employed in aerospace, military, automobile, and transport applications. The high-strength with low-weight materials required to fulfill the requirement of high-performance reinforced hard reinforcements obtain high-strength-to-weight properties for using process parameters fabrication technique define mechanical tribological properties. Many types optimiza...

The rapid expansion of a supercritical solution (RESS) process is a promising method for the production of small, uniform and solvent-free particles of solutes. The RESS containing a non-volatile solute leads to loss of solvent power by the fast expansion of the supercritical solution through an adequate nozzle, which can cause solute precipitation. The nozzle configuration plays an important r...
