Poland’s syndrome patients often seek medical interventions to improve their aesthetic appearances. Design and manufacturing technologies make it possible to produce custom-made implants for such medical conditions. The purpose of this study was to compare the 3D digital geometries that were designed using Magics and Geomagic^® Freeform^® for two anonymous case studies of Poland’s syndrome patients.

Computed tomography data were acquired and processed in Mimics^® to isolate the pectoralis muscles in STL file format. STL files were imported into Magics and Geomagic^® Freeform^® to design 3D digital geometries. Thereafter, comparative analyses were performed of the respective 3D digital geometries.

The angle between the vertical and oblique planes for both sides of the thorax was 6.5° for the female and 14° for the male. The surface areas and volumes of the geometries for the female were smaller than the male. Deviation analyses between the healthy side and reconstructed side of a thorax showed that 73 per cent of the test points for Magics and 78 per cent for Geomagic^® Freeform^® fell in the nominated tolerance region of >−5 and <+5 mm for the female. For the male, it was 83 per cent for Magics and 88 per cent for Geomagic^® Freeform^®.

Geomagic^® Freeform^® provides a more versatile design environment; however, the STL editor Magics may be an option to design 3D geometries for less intricate and less contoured implants.

This was a first attempt to compare the 3D geometries for Poland’s syndrome designed with an STL editor to those designed with a computer-aided design program.

This study aims to investigate how primary teachers, when taking part in digital didactic design (D³) workshops at the Digital Laboratory Centre at the university, develop their insights about how digital tools can be designed and further used in their teaching of science. The research question addresses how D³ can be used to develop primary teachers’ knowledge about teaching science with digital technologies.

During two semesters, 14 primary science teachers from three different schools participated in an in-service course at the university. Five D³ workshops lasting 4 h each were conducted with the aim to analyze, design and implement digital tools based on the needs of teachers and students. This includes discussions about the technological, pedagogical and content knowledge (TPACK) framework and further recommendations about how to choose, design, implement and evaluate digital tools for different teaching and learning situations. In between the workshops, the teachers were told to reflect on their experiences with colleagues and students and share their ideas and reflections to support collegial learning.

The results indicate that D³ has an opportunity to promote deep learning experiences with a framework that encourages teachers and researchers to study, explore and analyze the applied designs-in-practice, where teachers take part in the design process. This study further indicates that having teachers explicitly articulates their reasoning about designing digital applications to engage students’ learning that seems important for exploring the types of knowledge used in these design practices and reflecting on aspects of their teaching with digital technologies likely to influence their TPACK.

This research indicates that the increasing prevalence of information communication technology offers challenges and opportunities to the teaching and learning of science and to the scientific practice teachers might encounter. It offers solutions by investigating how primary teachers can design their own digital technology to meet students’ science learning needs. One limitation might be that the group of 14 teachers cannot be generalized to represent all teachers. However, this study gives implications for how to work with and for teachers to develop their knowledge of digital technologies in teaching.

As this project shows teachers can take an active part in the digital school development and as such become producer of knowledge and ideas and not only become consumers in the jungle of technical applications that are implemented on a school level. Therefore, it might well be argued that in science teaching, paying more careful attention to how teachers and researchers work together in collaborative settings, offers one way of better valuing science teachers’ professional knowledge of practice. As such, an implication is that digital applications are not made “for” teachers but instead “with” and “by” teachers.

The society puts high demands om teachers’ knowledge and competencies to integrate digital technologies into their daily practices. Building on teachers’ own needs and concerns, this project addresses the challenge for teachers as a community to be better prepared for and meet the societal challenge that digitalization means for schools.

Across the field of science education, knowledge about the relation between teachers’ use of digital technology and how it might (or might not) promote students’ learning offers access to ideas of how to design and implement teacher professional development programs. This offers enhanced communication opportunities between schools and universities regarding school facilities and expectations of technology to improve teachers’ experiences with integrating technology into their learning and teaching. This pragmatic approach to research creates theory and interventions that serve school practice but also produces challenges for design-based researchers.

This paper aims to explore the role of institutional and national policies in the design process of educational digital libraries developed collaboratively with key stakeholders within the African higher education context.

A qualitative research project based on three case studies of universities in Africa (Uganda, Kenya, Uganda) was carried out; comprising a retrospective review of the design process of ten innovative digital libraries through 38 in‐depth interviews with key design stakeholders. The interviews were conducted between September and December, 2009, while the data were triangulated with observations and documentary evidence from key policies.

Institutional and national policies were found to have tremendous impact on the design process of digital libraries as well as on their sustainability. Their absence in the design process was found to stifle innovation.

This research was limited to the design process of digital libraries in African higher education. The research findings suggest that policy makers are important design gatekeepers and as such digital library designers should actively review relevant national and institutional policies, incorporate the implications of policies into design processes, and help to develop relevant policies.

The paper provides an understanding of the critical impact policies have with respect to supporting the design of educational digital libraries that are developed collaboratively with stakeholders. The retrospective review of completed digital library design processes carried out offers a different methodological approach for obtaining a high level understanding of the phenomenon under investigation.

The aim of this paper is to provide a structured collection of case studies organized around the core discussion of how to address the subject of digital media in schools of design in general and architecture in particular. By means of these case studies it will be possible to understand the trajectory that we have followed in the Department of Architecture at Texas A&M University, having as main goal the incorporation of digital media instruction in design curricula and to assess whether our instructional methods and strategies are in tune with our present understanding of the role of digital media in design. The case studies have been organized following three main contextual themes, namely: shaping our understanding of the role of digital media in design, incorporating digital media in the design studio, and adapting to the availability of new technology. The paper includes the identification of critical issues, among them: polarization between traditional and digital media, solutions for continuous learning and update, and pervasive accessibility of digital means. The paper states conclusions and identifies the opportunities and challenges that we foresee in the near future based on the implementation of multidisciplinary integration and the development of multimodal and media-rich design environments.

Jacquard fabric is regarded as a “high-grade” textile, having intricate, interesting color and texture, and digital image design is the latest technique of computer art in the design field. Merging the design features of jacquard fabrics and digital image, this study was carried out to investigate digital jacquard fabric design in a colorless mode, which is one of the main modes of digital image design; another is that of a colorful mode. In this paper, the design principles and design methods for unconventional digital jacquard fabric design in a colorless mode were analyzed critically based on the application of digital technologies, and in particular, the digital color theory so that with tailor-made structural design, any colorless digital images with certain grays can be designed to form jacquard fabrics directly. The results of this study bring about an innovative design concept in jacquard fabrics and have a significant influence on the future development of jacquard textiles.

Traditionally, industrial power supplies have been exclusively controlled through analog control to sustain high reliability with low cost. However, with the perpetual decrement in cost of digital controllers, the feasibility of a digitally controlled switch mode power supply has elevated significantly. This paper aims to outline the challenges related to the design of digital proportional-integral (PI) controlled synchronous rectifier (SR) buck converter by comparing controller performance in continuous and discrete time. The trapezoidal approximation-based digital PI control is designed for low voltage and high-frequency SR buck converter operating under continuous conduction mode.

The analog and digital controller are designed using a SISO tool of MATLAB. Here, zero-order hold transform is used to convert the transfer function from continuous to discrete time. Frequency and time domain analysis of continuous plant, discrete plant and close loop system is performed. The designed digital PI control is simulated in MATLAB Simulink. The simulated results is also verified on hardware designed around digital signal processing control.

The continuous and discrete control loops are validated with multiple tests in the time and frequency domain. The detailed steady state theoretical analysis and performance of the SR buck converter is presented and verified by simulation. It is found that the delay in digital control loop results in a low phase margin. This phase margin decreases with higher bandwidth. The hardware experiments with the digital control loop are carried out on a 10 W prototype. The chosen parameters for the SR buck converter are found to be optimum for steady and transient state response.

This paper compares the digital and analog control approach of compensator design. It focuses on the implications created at the time of transforming the control design from continuous to discrete time. Further, it also focuses on the selection of parameters such as phase margin, bandwidth and low pass filter.

The use of digital-models to communicate civil-engineering design continues to generate debate; this pilot-work reviews technology uptake towards data repurposing and assesses digital (vs traditional) design-preparation timelines and fees for infrastructure. The paper aims to discuss these issues.

Extending (building-information-modelling) literature, distribution-impact is investigated across: quality-management, technical-applications and contractual-liability. Project case-study scenarios were developed and validated with resultant modelling-application timeline/fees examined, in conjunction with qualitative semi-structured interviews with 11 prominent stakeholder companies.

Results generated to explore digital-model data-distribution/usage identify: an 8 per cent time/efficiency improvement at the design-phase, and a noteworthy cost-saving of 0.7 per cent overall. Fragmented opinion regarding modelling utilisation exists across supply-chains, with concerns over liability, quality-management and, the lack of Australian-Standard contract-clause(s) dealing directly with digital-model document hierarchy/clarification/reuse.

Representing a small-scale/snapshot industrial-study, findings suggest that (model-distribution) must emphasise checking-procedures within quality-systems and, seek precedence clarification for dimensioned documentation. Similarly, training in specific file-formatting (digital-model-addenda) techniques, CAD-file/hard-copy continuity, and digital-visualisation software, can better regulate model dissemination/reuse. Time/cost savings through digital-model data-distribution in civil-engineering contracts are available to enhance provision of society’s infrastructure.

This work extends knowledge of 3D-model distribution for roads/earthworks/drainage, and presents empirical evidence that (alongside appropriate consideration of general-conditions-of-contract and specific training to address revision-document continuity), industry may achieve tangible benefits from digital-model data as a means to communicate civil-engineering design.
