Within the scope of the Royal Netherlands Navy’s Walrus class replacement programme, DMO embarked in 2015 in developing a set of tools to generate and assess submarine concept designs. MARIN took up the challenge to develop a design workflow SUPREME on the basis of its Quaestor3 knowledge engineering framework [van Hees 1997, 2003, 2009]. Within this workflow a number of proprietary and often confidential tools should be plugged in to perform e.g. propulsion system dimensioning, weight estimation and for assessment of trimming and compensation capabilities. These ‘satellite’ tools are mostly developed for, or by, DMO. As a design system, SUPREME becomes fully operational at DMO where workflow and proprietary tools come together. The developmental focus of MARIN is the SUPREME workflow which deals with design knowledge representation and design data management. The two major challenges in its development were the topological representation and the weight management methodology. This paper will discuss the first one, the development of a submarine topological representation using the CAD system RhinocerosTM as externally controlled geometry generator. This combines high accuracy with adaptability and enables naval architects to constantly monitor the weight and volume balances and trimming / compensation capabilities of concept submarines already in the earliest stages of design.

Privacy by Design (PbD) is the most common approach followed by software developers who aim to reduce risks within their application designs, yet it remains commonplace for developers to retain little conceptual understanding of what is meant by privacy. A vision is to develop an intelligent privacy assistant to whom developers can easily ask questions to learn how to incorporate different privacy-preserving ideas into their IoT application designs. This article lays the foundations toward developing such a privacy assistant by synthesising existing PbD knowledge to elicit requirements. It is believed that such a privacy assistant should not just prescribe a list of privacy-preserving ideas that developers should incorporate into their design. Instead, it should explain how each prescribed idea helps to protect privacy in a given application design context—this approach is defined as “Explainable Privacy.” A total of 74 privacy patterns were analysed and reviewed using ten different PbD schemes to understand how each privacy pattern is built and how each helps to ensure privacy. Due to page limitations, we have presented a detailed analysis in Reference [3]. In addition, different real-world Internet of Things (IoT) use-cases, including a healthcare application, were used to demonstrate how each privacy pattern could be applied to a given application design. By doing so, several knowledge engineering requirements were identified that need to be considered when developing a privacy assistant. It was also found that, when compared to other IoT application domains, privacy patterns can significantly benefit healthcare applications. In conclusion, this article identifies the research challenges that must be addressed if one wishes to construct an intelligent privacy assistant that can truly augment software developers’ capabilities at the design phase.

AbstractRecent research in technology-enhanced learning environments has indicated the need to redefine the role of teachers as designers. This supports successful learners better able to adapt to twenty-first century education, in particular STEM education. However, such a repositioning of teaching as a design science challenges teachers to reconceptualize educational practice as an act of design, not in the artistic meaning of the word. Our recent research finding also indicated that teacher design knowledge (TDK) processes are often invisible to both the teacher educators and the teachers. To respond to these challenges, this paper will define TDK for STEM teachers by making TDK visible in the form of a TDK competency taxonomy. A systematic literature review was conducted to identify the characteristics of teaching practices in technology-enhanced learning environments. This TDK competency taxonomy consists of four main categories drawing on existing literature on teacher design work and teacher instructional design: data practice, design practice, knowledge creation practice, and professional teaching practice. The implications of these findings were discussed.

Abstract This paper gives an overview of a collaborative design system (CDS) for electromechanical products. To reduce design costs and to manufacture high-quality products, it is well known that concurrent engineering (CE) is a very efficient approach. Three-dimensional (3D) CAD system and engineering database system are essential components of CE. The CDS is an environment to realize CE. By creating 3D models in a computer and performing some simulations such as mechanical, electronic, software simulation and integrated simulations, it is possible to estimate functions, assemblability, manufacturability and so on, before making prototype models. In this paper, we outline the CDS and mainly discuss the total information management system (TIMS) which makes an important role of the CDS. This paper describes the implementation experience of some functions of the TIMS.

The effective capture of legacy knowledge and information during all aspects of the product development cycle is one of the biggest remaining challenges in engineering companies. Life Cycle Engineering requires the capture of engineering information and knowledge created during design sessions to support knowledge reuse, product reengineering and training. In the past, many attempts have been made to determine if this is possible; however, those that are partially successful are very time consuming, expensive to implement and interrupt the engineers’ creativity. This work investigates and demonstrates new and novel paradigms for knowledge and information capture by adapting and applying a well recognised knowledge capture methodology to suit the non-intrusive automated real time logging, capture and post processing of engineering knowledge using a head-mounted display virtual reality (VR) design system. This logging is accomplished during individual cable harness design tasks carried out by 12 cable harness design engineers from five industrial partners to demonstrate the effective, unobtrusive and automatic capture and representation of various forms of engineering design knowledge and information. The formats were subsequently evaluated by the engineers to determining those they consider best at conveying design knowledge and information for other engineers.

This paper introduces the process of developing web application of farm management information system (FMIS) for smallholder farmers in Malaysia by using rapid application development (RAD) prototyping methodology in information system research design. FMIS is important ICT solution to assist smallholder farmer to be more competitive in agriculture. The web application requirement determined through extraction process using physical data-driven design system from Malaysia Good Agriculture Practise (MyGAP) physical forms. Additionally, the functions and features of the system were determined through several questionnaires which were distributed to 209 smallholder farmers located in Taman Kekal Pengeluaran Makanan (TKPM) in Selangor. Selangor agricultural area together with smallholders farmers were chosen as respondents because Selangor is the highest internet penetration state in Malaysia. Subsequently, the design and analysis of FMIS are constructed by us including the database design, data flow design, system flow design and software development which was validated by two other experienced system analysts. The software development process were using PHP web development tool called Scriptcase version 8 which were taking less than 2 months to be completed. Furthermore, we also made a comparative study of an existing system available in the market to give additional competitive value to the new development of FMIS in Malaysia. The final developed FMIS is accessible through the official MyAgris website.
