Vibration Suppression of a Fast Filament Fabrication 3d Printer via Resonance Compensation

Additive manufacturing systems especially 3d printers are made by rigid links which provide sufficient stiffness to give motion to 3d printing head system which are moving at very high speed &acceleration. It has been found out that high-speed manipulators generate vibration problem and 3dprinting head is one of them which encounter significant vibration at high speed and acceleration. Therefore, evolution in mathematical control system is necessary for effective vibration suppression and to allow fast motion of 3d printing head at high speed and acceleration. In this paper we develop experiment where we measure the resonance frequency of our bed swinging 3d printer and with graph we optimized it with mathematical system which allows printer to run 140% faster speed and over 600% higher acceleration with same quality and precision.

USING OF VIRTUAL REALITY TOOLS FOR THE DEVELOPMENT OF STEAM EDUCATION IN GENERAL SECONDARY EDUCATION

The article researches the use of virtual reality to support STEAM education in general secondary school. To study the impact of STEAM education, the authors proposed a teaching project for the secondary school about convex mirrors and their importance for special visibility and human safety, where the interviewed teachers were able to learn about a real example of the implementation of STEAM education for teaching their disciplines. The purpose of the article is to analyze the meanings and approaches to the use of virtual reality by teachers for organizing the STEAM-oriented learning environment and to identify the basic requirements to VR for supporting the implementation and development of STEAM education. One of the main trends of education modernization is STEAM education, which involves the integration of the natural sciences, the technological sciences, engineering, mathematics and art in the learning process, in particular, at general secondary schools. In light of the findings, researchers indicate that electronic educational resources (including VR & AR) are not only teaching tools for teachers but also a source of inspiration for students, which motivates and stimulates creative thinking. This is an important point considering that creativity is increasingly an important life skill that can help young people cope with the difficulties and uncertainties in their future careers in the fields of STEAM. Prospects for further research are seen in the creation of a model for assessing student performance in STEAM projects. The authors are planning to take into account the differences and features of the use of virtual reality for learning STEAM in schools in different countries, including Ukraine, Spain and Kazakhstan, when creating a multilevel model of STEAM-oriented learning environment using virtual reality tools. The purpose of the model is to evaluate not only the results of tests taken by students after learning this material but also their personal contribution to the final project product, their leadership skills, creative ideas and suggestions, abilities and skills in using ICT and VR in project research. In our next publications, we will focus on several Spanish and Kazakhstani secondary schools to detect the possible differences found in the use of virtual reality to support STEAM education in Ukrainian schools.

Sometimes Less, Sometimes More: Trends in Career and Technical Education Participation for Students With Disabilities

We leverage nationally representative data and statewide data from Washington to investigate trends in occupational career and technical education (CTE) participation for students with and without disabilities. Consistent with prior work, we document declines in occupational CTE participation since the early 2000s, but we provide the first evidence that this decline can be explained by movement out of courses that are no longer considered CTE. Under the definitions operating at the time, though, we show that participation by students with disabilities in applied science, technology, engineering, mathematics, and medical/health (STEMM) CTE courses has increased over time, both nationally and in Washington. These trends are encouraging given prior evidence linking applied STEMM-CTE participation to better long-term outcomes for students with disabilities.

STEAM Course Development and Design based on Design Thinking: A Case Study on “Self-induction Demonstrator”

STEAM education is a new direction of education reform in the 21st century. It can cultivate students’ ability to creatively solve practical problems, integrate and apply interdisciplinary knowledge. It is an effective way to help students master the 21st century’s abilities. All countries spare no effort to let it be local Take root. The integration of design thinking and STEAM education provides a good opportunity for students' comprehensive and creative development. Therefore, we use the D. School design thinking model developed by Stanford University to develop a STEAM course based on design thinking to improve students' STEAM literacy and the skills and abilities that company needs for high-quality development. This STEAM course takes "Self-induction Demonstrator" as the project theme, including five steps: Empathize, Define, Ideal, Prototype, and Test. It aims to provide a reference paradigm for the design and implementation of the K-12 STEAM course, and promote the deep integration of science, technology, engineering, mathematics and art.

Sampling from Complex Probability Distributions: A Monte Carlo Primer for Engineers

Models which are constructed to represent the uncertainty arising in engineered systems can often be quite complex to ensure they provide a reasonably faithful reflection of the real-world system. As a result, even computation of simple expectations, event probabilities, variances, or integration over utilities for a decision problem can be analytically intractable. Indeed, such models are often sufficiently high dimensional that even traditional numerical methods perform poorly. However, access to random samples drawn from the probability model under study typically simplifies such problems substantially. The methodologies to generate and use such samples fall under the stable of techniques usually referred to as ‘Monte Carlo methods’. This chapter provides a motivation, simple primer introduction to the basics, and sign-posts to further reading and literature on Monte Carlo methods, in a manner that should be accessible to those with an engineering mathematics background. There is deliberately informal mathematical presentation which avoids measure-theoretic formalism. The accompanying lecture can be viewed at https://www.louisaslett.com/Courses/UTOPIAE/.
