The Design of Experiments (DOE) approach is a way of applying statistics to experimentation in a methodical manner. Because experimenting is so common in industries, most engineers (and scientists) end up analyzing their trials with statistics. Although there is a general set of rules and processes for performing the design of experiments (DOE), the literature lacks a recommended course of action for identifying and selecting the optimal design of experiments from a vast number of viable designs...

This study explores the impact of process parameters
and infill patterns, namely zig-zag and gyroid, on Fused Deposition Modelling
(FDM) 3D printing. The research investigates how variations in critical
parameters like nozzle temperature, print speed, and bed temperature, coupled
with different infill patterns, influence the mechanical performance of printed
specimens. Tensile and flexural tests were conducted to assess strength,
stiffness, and resilience. Results indicate that infill patte ...

In the present study, the effect of titanium content on the structure, electrical conductivity and mechanical properties of Cu-3wt%Si alloys were investigated. The experimental alloys were produced with various titanium concentrations of 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, 1.5%, 2% and 3% by weight using permanent mould casting technique. Tensile, hardness, impact and conductivity tests were carried out on the cast samples. Micro-structures of the specimens were also analyz...

Workers in Devki are exposed to several occupational hazards resulting in an average of three workers going on sick leave monthly. The management sought to reduce these incidences using a leading indicator through Safety Culture. Determining the safety culture was the main study objective. Independent variables were artefacts, espoused values and basic assumptions. The study made use of an analytical cross sectional design. The study population was 800 permanent employees from which a sample of ...

Diclofenac (DCF) is a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain in joint-related diseases. It is not completely metabolized after consumption and cannot be easily removed using conventional wastewater treatment. DCF has been detected in water bodies and may pose chronic effects on the endocrines of living organisms even at low-level exposure. Heterogeneous photocatalysis provides an alternative and efficient method of degrading DCF. In this study, the photocatalytic remov...

As one of the magnetorheological materials, magnetorheological elastomer (MRE) possesses unique solid properties that give it excellent mechanical properties. In the presence of an external magnetic field, the force, magnetic and electrical properties of the MRE also vary with the magnitude and direction of the magnetic field. This has led to a wide range of applications in the field of shock absorbers. This paper presents the properties of magnetorheological elastomers and the latest research s...

In this paper, HSC software was used to perform a thermodynamic analysis of A5083/ZrO 2 metal matrix composite to predict the phases which formed during the manufacturing processes (vortex method). The base matrix was purchased commercially and the zirconia particles were extracted from Egyptian zircon as a reinforcing material by alkaline fusion technique. The base material was melted in an electric furnace at 750°C, and the extracted zirconia particles were added while stirring. ...

Mineral coal presents a historical chronology to society, mainly regarding energy generation, and is outstanding in relation to oil when the subject is electricity generation, besides being utilized in the cosmetics and coal gas industry. Thus, the production chain that uses mineral coal must be validated for quality, considering specific prerequisites that show the positivity of this analysis. For this purpose, the present study was characterized by a Systematic Literature Review (SLR), aiming ...

This work proposes a design process for customizing three-dimensional (3D) printed shoe insoles to improve an individual’s footwear comfort based on body weight index and activity requirements. The purpose of this research is that people with various types of feet can benefit from these customizable insoles. PolyFlex Thermoplastic Polyurethane (TPU) materials based on the Fused Deposition Modeling (FDM) technique were investigated in this study. Samples with different infill patterns (Triangle, ...
