Radical Sources of Design Engineering

The German architect and structural engineer, Werner Sobek is internationally renowned for his expertise in lightweight structures - an approach that is epitomised by the dramatic elegance of his glazed House R128. Here, Sobek explains how his practice has extended a highly specialised focus on ultra-lightweight facades to that of building structures, facade planning, and sustainable and low-energy solutions, interweaving research and innovation with design and consultancy work.

GOING AFIELD: EXPERIMENTING WITH NOVEL TOOLS AND TECHNOLOGIES AT THE PERIPHERY OF LANDSCAPE ARCHITECTURE

Landscape architects are facing unprecedented challenges and complexities associated with design projects of today. To better adapt and evolve in light of these issues, the toolbox for the profession is currently expanding beyond traditional implements and devices to include emerging tools that have originated in other industries. The barriers to entry for these tools are continuously being lowered due to more user-friendly hardware, more intuitive software, and increased affordability, allowing them to get into the hands of more people. Yet, many of these emerging tools now available to professionals originated elsewhere and cannot be simply transferred over to the design world. This article argues that there is a need to critically evaluate and assess new technologies for use in landscape architectural practice. It unpacks how the XL Research and Innovation Lab at SWA Group has experimented with and tested the limitations of three new tools — unmanned aerial vehicles, immersive environment technologies, and machine learning algorithms — to better understand their potential for design. For each tool, the article provides an overview of its technology, a case study testing the technology for use in landscape architectural practice, a list of observed strengths and limitations, and a projected roadmap for future applications.

Investigating the quality of student approaches to using technology in experiences of learning through writing

This study reports on the student experience of learning through writing in an undergraduate science subject. During their writing experience, 52 first year university science students used a writing database, bulletin board and word-processor. Using quantitative questionnaires developed from student learning research, this study investigates the quality of the approaches adopted by students to the use of the technologies and how this related to the quality of their whole experience and performance measures. The results show that students who adopted a surface or reproductive approach tended to achieve relatively poorer learning outcomes and lower performance measures than students who adopted approaches which reflected understanding. The findings have important implications for teachers introducing technologies into writing processes for the purpose of improving students’ learning outcomes.     

Achieving e-Manufacturing: multihead control and web technology for the implementation of a manufacturing execution system

Intelligent Manufacturing Systems requires advanced and efficient manufacturing technologies, management and procedures in order to achieve value creation in global markets. E-Manufacturing is the set of information technologies that allows companies to achieve on demand manufacturing through the integration of e-business applications. Cornerstone of this concept are Demand Flow Technology, Manufacturing Execution Systems (MES) and Digital Operational Method Sheets (OMS) which are vital to control shop floor operations where there is a need to balance manual and automated operations. Specially, Mexican companies face large diversity of products and multiple production lines, with high turnaround rotation of the workers. A low cost solution that integrates Demand Flow Technology, MES with Digital OMS is described, the system has been developed using LINUX servers, Multi-head control technology (multiple monitors to a single server) and a WEB based environment. This technological solution offers an affordable, stable, and high performance solution to transform the production into a more balanced system with shorter and faster cycles allowing a company to achieve e-Manufacturing.
