The Impact

The impact of climate design on architecture is obvious. But design trends are currently attempting to implement climate design merely as an additional item in architectonic planning. The alternative is to start with an architectural attitude that will produce a comprehensively integrated design. To achieve this, design teams must accept the equal importance of all relevant aspects and have an understanding of the demands they make. This Imagine book is related to a series of lectures given at the TU Delft and a workshop in which international professionals and students from various disciplines took part with the intention of creating an ambience deliberately oriented toward the generation of an integrated, performancedriven envelope.

Abstract In order to solve the application restrictions of deterministic-based topology optimization methods arising from the omission of uncertainty factors in practice, and to realize the calculation cost control of reliability-based topology optimization. In consideration of the current reliability-based topology optimization methods of continuum structures mainly based on performance indexes model with a power filter function. An efficient probabilistic reliability-based topology optimization model that regards mass and displacement as an objective function and constraint is established based on the first-order reliability method and a modified economic indexes model with a composite exponential filter function in this study. The topology optimization results obtained by different models are discussed in relation to optimal structure and convergence efficiency. Through numerical examples, it can be seen that the optimal layouts obtained by reliability-based models have an increased amount of material and more support structures, which reveals the necessity of considering uncertainty in lightweight design. In addition, the reliability-based modified model not only can obtain lighter optimal structures compared with traditional economic indexes models in most circumstances, but also has a significant advantage in convergence efficiency, with an average increase of 44.59% and 64.76% compared with the other two reliability-based models. Furthermore, the impact of the reliability index on the results is explored, which verifies the validity of the established model. This study provides a theoretical reference for lightweight or innovative feature-integrated design in engineering applications.

Purpose The purpose of this paper is to explore certain resources, capabilities and competencies needed to improve the performance of physical asset management (PAM). Design/methodology/approach The analytic hierarchy process (AHP) is used to select and prioritize the most appropriate factors for improving performance. A multi-criteria approach is used to analyze and compare the importance of 6 main criteria and 18 subcriteria identified from a survey of relevant literature. Findings The study revealed that not all factors are viewed as having equal importance in improving PAM performance, as three of the main factors attained greater importance among the six factors. Research limitations/implications This study explored the factors required for managing assets only within the third stage of asset lifecycle, that is, the utilization stage. It is recommended that future studies be conducted in such a way as to determine the importance of similar factors in the other stages of the asset lifecycle, or to identify new factors and add new criteria. Practical implications Knowledge of the differential impacts of the factors on the performance of PAM can impact asset managers and decision makers in their allocation of resources and focus their work on the highest-ranked rather than the lowest-ranked factors. Also, AHP used provides an effective mean for asset managers to identify priorities among decision criteria in their organization. Originality/value To date, no study has explored the impact of six combined factors on the performance of PAM. Previous studies have found that these factors each had equal importance. However, their relative ranking in practice and when they appear together have remained unrecognized.

At Rowan University, design has been infused into the curriculum through an eight-semester course sequence called the Engineering Clinics. Through this experience, students learn the art and science of design in a multidisciplinary team environment and hone their design skills throughout their 4-year career. This paper describes the objectives of the clinics, types of projects, and how the clinics complement traditional core courses in the curriculum. Impacts and benefits of the clinics on students and faculty are discussed, including retention and graduate study rates comparing Rowan University mechanical engineering students to their peers nationally. An assessment of the clinics is presented based on survey data and accreditation objectives and outcomes. Survey data from students were assessed to determine levels of students’ satisfaction and confidence based on the clinics. Results of alumni and employer surveys also provide valuable feedback for assessing and improving the clinics as well as confirmation of the impact of clinics after graduation. Survey data are discussed along with challenges of the clinics at Rowan and adaptability of them at other institutions. Overall, the clinics are a positive and integrated design experience in the curriculum and assist students in achieving the program objectives.

Engineering Projects

This paper describes exploratory research regarding leadership and communication within undergraduate engineering design teams. The case study was performed on student design projects of one and two semester duration to begin to assess the impact of project length on leadership and communication within the design teams. Data was collected using a survey that was given to the participants in three capstone design projects in Clemson University’s senior design course. The survey was administered within one month of course and project completion. While there were differences in the communication and leadership patterns between the teams, there were other possible influences beyond the project length such as team size and organization, organizational and geographic distribution, and the nature of the product. As a result, further research is proposed to study leadership and communication structures within undergraduate teams and multi-team systems (MTS).

In this paper, the authors aimed to analyze uncertain nonlinear networked control systems (NCS) under discrete event-triggered communication scheme (DETCS), in which an integrated design methodology between robust fault detection observer and active fault-tolerant controller is proposed. Moreover, the problem of hybrid active–passive robust fault-tolerant control, which integrated passive fault-tolerant control, fault detection, and controller reconstruction, is researched. In consideration of the impact of uncertainties and network-induced delay on system performance, a new class of uncertain nonlinear NCS fault model is established based on T-S fuzzy model. By employing Lyapunov stability theory, H∞ control theory, and linear matrix inequality method, the fault detection observer and hybrid fault-tolerant controller are both appropriately designed. In addition, the sufficient condition that guaranteed the asymptotically robust stability of nonlinear NCS against any actuator failures is deduced. Finally, a numerical simulation is provided to show the effectiveness of the proposed methods.

BACKGROUND Multidisciplinary collaboration is essential to the successful development of serious games, albeit difficult to achieve. The co.LAB serious game design framework was created to support collaboration within serious game multidisciplinary design teams. Its use has not yet been validated in a naturalistic context. OBJECTIVE The objective of this study was to perform a first assessment of the impact of the co.LAB framework on collaboration within multidisciplinary teams during serious game design and development. METHODS This was a mixed-methods study based on two serious game design projects in which the co.LAB framework was used. The first phase was qualitative and carried out using a general inductive approach. To this end, all members of the first serious game project team who used the co.LAB framework were invited to take part in a focus group session (N=6). Results inferred from qualitative data were then used to define a quantitative instrument (questionnaire) which was designed according to the Checklist for Reporting Results of Internet E-Surveys. Members of both project teams (N=11) were then asked to answer the questionnaire. Quantitative results were reported as median [Q1;Q3] and appropriate non-parametric tests used to assess for between group differences. Finally, results gathered through the qualitative and quantitative phases were integrated. RESULTS In both phases, the participation rate was 100%. Verbatim transcripts were classified into 4 high level themes: influence on collaborative dimensions; impact on project course, monitoring and efficiency; qualitative perceptions of the framework; and influence of team composition on the use of the framework. Accordingly, the web-based questionnaire was then developed according to Burhardt's seven dimensions of collaboration. In both projects, the co.LAB framework had a positive impact on most dimensions of collaboration during the multidisciplinary design and development of serious games. When all collaborative dimensions were aggregated, the overall impact of the framework was rated on a scale from "-42" to "+42" (very negative to very positive). The overall score was 23 [20;27], with no significant difference between groups (P=.58). Most respondents also believed that all serious game design teams should include a member possessing a significant expertise in serious game design frameworks to guide the development process. CONCLUSIONS The co.LAB framework has a positive impact on collaboration within serious game development teams. However, expert guidance seems necessary to maximize development efficiency. Whether such guidance can be provided by means of a collaborative web platform remains to be determined.

The Impact

This study aimed to examine the impact of the design teams approach on preservice teachers’ technological pedagogical and content knowledge (TPACK). Using a mixed-method design, the researcher implemented the investigation among 62 teacher candidates whose major was Primary English Teaching at a university of foreign language studies in Central Vietnam. All of the participants attended a course named “Technology in Education”, which was adapted based on Johnson’s design teams approach model (2014). The data were collected using pre- and post-TPACK Survey, a TPACK Rubric (TIAI) and semi-structured interviews. The findings indicated that this design teams approach had a significant impact on the participants’ TPACK, particularly its technology-related knowledge domains (TK, TPK, TCK, TPACK). The result was also confirmed by the teacher candidates’ positive responses about their perceptions towards this instructional approach.

The Impact

Drastic changes are occurring in the construction industry. Building Information Modeling (BIM) processes and technologies, and new Integrated Project Delivery (IPD) approaches are transforming the way buildings are planned, designed, built and operated. With the needs for new skills to cope with these accelerating changes, architecture, engineering and construction (AEC) associations in the United States are working with universities to reengineer teaching programs, integrating architecture training within an engineering and construction curriculum. Leading universities are already developing new programs, such as BIM studio courses, and promoting new ways to teach practice knowledge within design laboratories.These changes are also starting to occur in the Canadian industry. Some large governmental bodies are starting to request that their projects are designed and built using BIM. Canadian universities must respond to these changing requirements to prepare future architects, engineers, and construction managers for these new challenges and emerging industry needs. This paper provides examples for how to bridge this gap by bringing practice knowledge and research to the classroom. First, it synthesizes the impact of BIM and IPD on engineering practices in Canada. Second, it describes curriculum development undertaken between a school of architecture and two engineering departments for the development of multidisciplinary design studios to teach integrated design and BIM. Case studies are set in urban contexts and include the development of new buildings as well as refurbishment proposals for an industrial obsolete landmark. Finally, learning from this teaching and research experience, it raises questions and issues regarding our readiness to cope with this paradigm shift.
