Parallel Kinematic

This paper introduces the theoretical design of reconfigurable machine tools using modular design approach. First, the general concept of modular robot and its growing need is introduced. Second, the design of reconfigurable parallel kinematic machines is discussed and the geometric modeling of such figures is presented and explained, and potential applications are described. Finally, a case study for proposed structure is conducted for its kinematic modeling and design optimization and some results are concluded.

Parallel Kinematic Machine Tools

This paper introduces the theoretical design and control of reconfigurable parallel kinematic machine tools. First, the general concept of reconfigurable parallel kinematic machine (RPKM) and its growing demand are introduced. Second, the design of reconfigurable parallel kinematic machines is discussed and the geometric modeling of such structures is presented and explained. The potential applications of this type of machine are described. Finally, a case study for one of the proposed structures is conducted, including kinematic/dynamic modeling and control, some results and simulation are demonstrated.

High-entropy alloys (HEAs) have been around since 2004. The breakthroughs in this field led to several potential applications of these alloys as refractory, structural, functional, and biomedical materials. In this work, a short overview on the concept of high-entropy alloys is provided, as well as the theoretical design approach. The special focus of this review concerns one novel class of these alloys: biomedical high-entropy alloys. Here, a literature review on the potential high-entropy alloys for biomedical applications is presented. The characteristics that are required for these alloys to be used in biomedical-oriented applications, namely their mechanical and biocompatibility properties, are discussed and compared to commercially available Ti6Al4V. Different processing routes are also discussed.

Interest And Motivation

In order to be well-educated citizens in the 21st century, children need to learn computing in school. However, implementing computing education in schools faces several practical problems, such as lack of computing teachers and time in an already overloaded curriculum. A solution can be a multidisciplinary approach, integrating computing education within other subjects in the curriculum. The present study proposes an instructional unit for computing education in social studies classes, with students learning basic computing concepts by programming history related games using Scratch. The instructional unit is developed following an instructional design approach and is applied and evaluated through a case study in four classes (5th and 7th grade) with a total of 105 students at a school in (omitted for submission). Results provide a first indication that the instructional unit enables the learning of basic computing concepts (specifically programming) in an efficient, effective and entertaining way increasing also the interest and motivation of students to learn computing.
