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...

An analysis is conducted on eleven governorates in Oman to assess the environmental and financial advantages of implementing a solar hot water system. The conservation of natural gas is measured by comparing it to the absorption of solar energy on a daily, monthly, and yearly basis. The study considers the monetary value of natural gas and the duration required to recover the initial investment in order to evaluate the environmental and economic benefits. Muscat realises its maximum capabilities...

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...

Virtual instrument technology is widely used in the field of information engineering. Based on the concept of OBE, this paper carries out the teaching reform of virtual instrument technology and application course, optimizes the teaching content from the training goal, updates the teaching method with students as the center, improves the assessment standard with the evaluation of learning results, and puts forward the measures to ensure continuous improvement. Practice shows that the reform has ...

This project presents a comparative study of the mechanical properties of Acrylonitrile Butadiene Styrene (ABS). The specimens per ASTM D638 type IV were fabricated by injection molding, compression molding, and 3D printing. ABS is recommended for the precision machining of ABS structural parts. ABS has a good balance of impact, heat, chemical resistance, dimensional stability, tensile strength, and surface hardness. ABS pallets from one batch are used in compression molding, injection molding, ...

Taking engineering education certification as an opportunity, combined with the training goal of engineering practice talents in the earthquake industry, the teaching reform of “Microcomputer Principle and Application” course under the concept of OBE (Outcome Based Education) was explored, including optimizing the theory teaching driven by industry characteristic application cases, and setting hierarchical software and hardware development experiments of a microcomputer system. Integrated EMU808...

Based on the current situation of “EDA” (Electronic Design Automation) course teaching, combined with the feedback of students, this paper summarizes and analyzes the main problems existing in the current “EDA” course teaching, such as the general theory of teaching, practice teaching hours are slightly insufficient, the course teaching effect is not good. This paper gives some suggestions on teaching reform from the aspects of teaching content, course assessment method and teacher team construc...

Aiming at the problems that the traditional teaching process of “Automatic Test System” course is mainly based on the single teaching of theoretical knowledge, the practice teaching is separated from the engineering reality and the course evaluation is not reasonable, the reform exploration is carried out from the aspects of teachers’ ability, teaching content and evaluation method, combined with the CDIO (Conceiving Designing Implementing and Operating) model and the project teaching concept. F...

The teaching practice and the problems in traditional teaching of principle of single-chip microcomputer and application course are expounded. In order to improve the application ability of students, with the concept of OBE, the integrated teaching mode of theory and practice teaching is adopted. From multiple perspectives, the cultivation of application ability is enhanced through teaching content, teaching methods and assessment methods. Students are encouraged to design independently, and pra...

Artificial electric field (AEF) algorithm is a newly developed heuristic intelligent optimization method, which has the advantages of simple implementation process and less control parameters. So far, it has been applied in some engineering and scientific research fields. For these reasons, AEF algorithm is used to address six benchmark functions to evaluate its search ability. After that, AEF algorithm is combined with BP neural network to find the optimal initial weights and biases, and then t...
