Using 3D design technology and a combination of carbon fiber and 16% HGM epoxy resin, female troops are wearing bulletproof vests

Women are becoming more active in the defense industry. Since the morphology of the female body differs from that of the male during military activities, it is required to modify personal protection equipment to accommodate the female body shape. According to a literature review, a survey of a sample of female soldiers from different nations revealed that they felt the impacts of breast soreness when running, as well as a sense of "distorted breasts" and breathing difficulties. The woman's petite frame and the bulky, hefty bulletproof jacket both draw criticism for their respective dimensions. Using 3D design technology, a female mannequin with a 95B breast size was scanned in order to create a bullet-proof vest that is tailored to the contour of a woman's body. Changes in the breast's contour, which affect changes in the surface point parameters, result in adaptive breasts. Utilizing a combination of carbon fiber and 16% HGM epoxy, bullet-proof vests can be modified to provide lightweight dimensions and have the benefit of good ballistic resistance. This results in a material that is 20 mm for thick, 1,348 kg in weight, and capable of absorbing 348.27 Joules of energy from bullets. The results of this research are not optimal, so developments are needed in further research.

An Efficient Partitioning Algorithm Based on Hypergraph for 3D Network-On-Chip Architecture Floorplanning

Network-on-Chip (NoC) supplies a scalable and fast interconnect for the communication between the different IP cores in the System-on-Chip (SoC). With the growing complexity in consumer embedded systems, the emerging SoC architectures integrate more and more components for the different signal processing tasks. Two dimensional Network-on-Chip (2D NoC) becomes a bottleneck for the development of the SoC architecture because of its limitation on the area of chip and the long latency. In this case, SoC research is forcing on the exploration of three dimensions (3D) technology for developing the next generation of large SoC which integrates three dimensional Network-on-Chip (3D NoC) for the communication architecture. 3D design technology resolves the vertical inter-layer connection issue by Through-Silicon Vias (TSVs). However, TSVs occupy significant silicon area which limits the inter-layer links of the 3D NoC. Therefore, the task partitioning on 3D NoC must be judicious in large SoC design. In this paper, we propose an efficient layer-aware partitioning algorithm based on hypergraph (named ELAP-NoC) for the task partitioning with TSV minimization for 3D NoC architecture floorplanning. ELAP-NoC contains divergence stage and convergence stage. ELAP-NoC supplies firstly a multi-way min-cut partitioning to gradually divide a given design layer by layer in the divergence stage in order to get an initial solution, then this solution is refined in convergence stage. The experiments show that ELAP-NoC performs a better capacity in the partitioning of the different numbers of cores which supplies the first step for the 3D NoC floorplanning.

By design: Professional learning ecologies to develop primary school teachers’ makerspaces pedagogical capabilities

AbstractMakerspaces embody a growing movement of educators promoting constructionist learning with physical materials and digital technologies such as 3D design and 3D printing. As it gains traction in K‐12 settings, the maker movement represents an interesting context in which to explore how professional ecologies can equip teachers with the knowledge, skills and dispositions needed to implement twenty‐first century learning in their school context. This study investigated the roles of different participants from industry, school leadership and colleagues in influencing teachers’ confidence, enthusiasm, capabilities and beliefs when teaching in makerspaces. Utilising triangulated observations of activities through online questionnaires at beginning, middle and end points, as well as postproject interviews, the study explored the participation of 27 primary school teachers in a blended professional learning programme, followed by classroom delivery of modules focusing on tablet‐based 3D design applications and the use of newly instaled 3D printers. Reporting no prior knowledge or experience with makerspaces, quantitative analyses revealed significant increases in teachers’ confidence and enthusiasm. Qualitative analyses of questionnaire and interview data underscored the influence of hands‐on and theoretically grounded professional learning providing practical exposure to constructionist ideas, design thinking methodologies and 3D design technologies. Findings reveal the importance of targeted professional learning coupled with a substantial collegially supported implementation phase, as well as support from school leaders and industry partners to promote meaningful pedagogical change in technology‐mediated maker‐based learning.

A Creative 3D Design Programme: Building on Interests and Social Engagement for Students with Autism Spectrum Disorder (ASD)

This study explores the processes occurring during technology workshops which built on interests and enhanced social engagement for students with autism spectrum disorders (ASD). The workshops used a community based research design and focused on teaching a creative three-dimensional (3D) design programme (SketchUp™) to students with ASD. Seven boys (ages 8–17) participated in this pilot programme over a 6-month period. The methodology was a qualitative thematic analysis of videotapes and transcripts of workshop sessions. The two key themes that emerged were: (1) development of authentic peer relationships through humour, common interests, physical actions, and playful competition; and (2) the importance of a scaffolded learning environment with support from peers and an adult mentor, as opportunities for social engagement. These findings indicate that 3D design technology can build on strengths and interests of students with ASD and promote social engagement in naturally occurring environments. A positive youth development philosophy focusing on technology interests may be useful with students with ASD, especially in connection to existing service delivery models.
