The surface roughness of wood has a great influence on its performance and is very important indicator in processing manufacturing. In this paper, we use the central composite design experiment (CCD experiment) artificial neural network (ANN) model to study changing pattern during high-speed milling process pine wood. CCD experiments, spindle speed, feed depth cut are used as influencing factor...

In this research, nickel ferrite (NiFe2O4) nanoparticles (NFNs) are prepared through coprecipitation method, and applied for adsorption removal of a model organic pollutant, methyl orange (MO). The characterization of t...

Osmotic dehydration is an important phase in the production of dried products, including most fruits and vegetables, food industry. The drying process for candied fruit produces a liquid waste called “spent osmotic solution”, which characterized by high content organic compounds, mostly dissolved sugars. sugar this by-product could be valorized through growth biomass with added value. In study,...

It is widely acknowledged that the blended elemental (BE) powder metallurgy (PM) Ti6Al4V alloy attracted unusual due to its low cost and comprehensive mechanical properties. However, high porosity mediocre properties of traditional vacuum sintering limited application. To achieve better performance, central composite designs (CCDs) method was employed analyze influence parameters, such as tempe...

The hypoeutectic aluminum alloy (AlSi10Mg) is a well-known candidate material used predominantly for its processability and inherent characteristics in metal-based additive manufacturing. Besides, transition metal carbide, such as niobium carbide (NbC), added to the AlSi10Mg, enhancing mechanical properties preferably wear resistance matrix. However, manufacturing, mixed powder’s flowability pr...

Algal biomass from Spirulina platensis has been tested for the adsorption of chromium (VI) in aqueous effluents. The study was conducted using a central composite experimental design. selected variables were: (0.25–0.75 mg), initial concentration (100–500 mg/L), and contact time (3–8 h). This proved that spirulina shows good capacity space design (CCD). maximum 40 mg Cr/g tests with 500 mg/L Cr...
