The brand is a powerful representational and identification-led asset that can be used to engage staff in creative, sustainable and developmental activities. Being a brand the result of, foremost, a design exercise, it is fair to suppose that it can be a relevant resource for the advancement of design literacy within organisational contexts. The main objective of this paper was to test and validate an interaction structure for an informed co-design process on visual brand artefacts. To carry on the empirical study, a university was chosen as case study as these contexts are generally rich in employee diversity. A non-functional prototype was designed, and walkthroughs were performed in five focus groups held with staff. The latter evidenced a need/wish to engage with basic design principles and high willingness to participate in the creation of brand design artefacts, mostly with the purposeof increasing its consistent use and innovate in its representation possibilities, whilst augmenting the brand’s socially responsible values.

<p>A basic procedure for designing a power inductor is presented. Many papers and textbook chapters offer more sophisticated methods, but it is harder to find a clear outline of a basic design process. Studying and practicing a basic design process is useful for beginners to understand the fundamental tradeoffs in design and to build intuition. For more advanced work, the basic design process is useful as it avoids relying on assumptions that might not be valid with, for example, high-frequency loss effects that are ignored in the development of some more sophisticated methods, or that constrain other methods to narrow, specific cases.</p> <p>Two options are outlined: starting with a saturation constraint, and then checking the core/winding loss balance; or, starting by optimizing the core/winding loss balance, and then checking the saturation constraint.</p>

Purpose The preliminary aircraft design process comprises multiple disciplines. During performance analysis, parameters of the design mission have to be optimized. Mission performance optimization is often challenging, especially for complex mission profiles (e.g. for unmanned aerial vehicles [UAVs]) or hybrid-electric propulsion. Therefore, the purpose of this study is to find a methodology that supports aircraft performance analysis and that is applicable to complex profiles and to novel designs. Design/methodology/approach As its core element, the developed method uses a computationally efficient C++ software “Aircraft Performance Program” (APP), which performs a segment-based mission computation. APP performs a time integration of the equations of motion of a point mass in the vertical plane. APP is called via a command line interface from a flexible scripting language (Python). On top of APP’s internal radius of action optimization, state-of-the-art optimization packages (SciPy) are used. Findings The application of the method to a conventional climb schedule shows that the definition of the top of climb has a significant influence on the resulting optimum. Application of the method to a complex UAV mission optimization, which included maximizing the radius of action, was successful. Low computation time enables to perform large parametric studies. This greatly improves the interpretation of the results. Research limitations/implications The scope of the paper is limited to the methodology that allows for advanced performance analysis at the conceptual and preliminary design stages with an emphasis on novel propulsion concepts. The methodology is developed using existing, validated methods, and therefore, this paper does not contain comprehensive validation. Other disciplines, such as cost analysis, life-cycle assessment or market analysis, are not considered. Practical implications With the proposed method, it is possible to obtain not only the desired optimum mission performance but also off-design performance of the investigated design. A thorough analysis of the mission performance provides insight into the design’s capabilities and shortcomings, ultimately aiding in obtaining a more efficient design. Originality/value Recent developments in the area of hybrid or hybrid-electric propulsion systems have shown the need for performance computation tools aiding the related design process. The presented method is especially valuable when novel design concepts with complex mission profiles are investigated.

Specific Contribution

Well-being is an ephemeral condition in relation to the complex system of interconnected components changing from culture to culture and person to person together with time and space. Therefore, it is very important to investigate the intersections of architecture and humanities in order to understand how design can contribute to the way we build up well-being. The specific contribution of this chapter is the introduction of the well-being framework for interiors and its application to design process. The framework proposal, consisting of contextual, functional, psychological, social, ergonomic, aesthetic, and sensory requirements as basic design criteria, aims to support both theoretical and practical activities regarding well-being in all living environments. Since interior space is one of the most important determinants of our everyday experiences, its role in well-being as a conscious construct needs to be an important concern of spatial design.

Purpose Digital media is reshaping architectural design by introducing new tools, methods and workflows. Among various AEC tools, Building Information Modeling (BIM) has gained popularity due to its collaboration platform enabling cross-disciplinary teamwork during whole life cycle of buildings. BIM has further transformed culture and processes associated with design, construction and operation of buildings, hence triggering new building regulations in developed countries. However, in developing countries, BIM implementation is facing several barriers, such as lack of investment in technology and training, hesitation in quitting traditional tools and practices, etc. The purpose of this paper is to highlight potentials of BIM for developing countries, which are in need of more sustainable policies for enhancing their economic and environmental performances. Design/methodology/approach Throughout the text, a literature review on BIM including its dimensions and benefits, impacts on architectural design and adoption in global and local contexts is provided. In case study, surveys and structured interviews are conducted with BIM user and non-BIM user architects throughout Pakistan. Beyond 2D/3D modeling, the use of BIM applications for sustainable design process such as scheduling (4D), cost estimation (5D), performance analysis and facilities management (6D) is investigated. Findings Using analytical tools of an online surveying tool and SPSS statistical software, barriers and motivations for BIM implementation in Pakistan are determined. Strategies for further BIM adoption and implementation via “education and training institutions” and “supporting organizations and institutions” are defined. Originality/value As a developing country, Pakistan shall be moving the barriers for the spread of BIM technology. Recent research covered the entire AEC sector (Masood et al., 2014; Sohu et al., 2017; Ali et al., 2018), yet this paper focuses specifically on architectural design and practice field. In order to find out experiences and expectations about BIM technology in the architecture sector, professionals are surveyed and four chief architects are interviewed. How far have Pakistani architects adopted BIM? For which project types and scales is BIM more serviceable for them? Which BIM applications are they implementing to overcome the limitations in their professional practice? In Pakistan, where sustainability, in terms of scheduling, cost estimation, performance analysis and facilities management, is an indispensible measure for local practices, has implementation of BIM technology achieved sustainability in architectural design process? What are the motivations of Pakistani architects for becoming BIM users in future?
