Minimum Performance

Traditional engineering design practice seeks to create reliable systems that maintain a desired minimum performance when subjected to a defined set of impulses. To manage impulses, designers implement techniques to specify systems that are resilient or robust to impulses. Resilient systems perform with degraded capacity when subjected to impulses while robust systems remain unaffected by impulses. In this paper we examine antifragility, a complement to resilience and robustness, to manage the impulse response of complex cyber systems. Where fragile systems fracture when subjected to impulses, antifragile systems become stronger. We discuss why this strengthening characteristic makes antifragility attractive for managing impulse response in complex cyber systems and develop a measure for antifragility that differentiates it from fragility, resiliency and robustness. We then discuss an antifragile cyber system to demonstrate the benefits of antifragility in an impulse-rich environment.

This chapter argues that, just as technological artefacts can break as a result of mechanical, electrical, or other physical defects not fully accounted for in their design, they can also break as a result of social defects not fully accounted for in their design. These failures resulting from social defects can be called social failures. The chapter then proposes a definition of social failure as well as a taxonomy of social failure modes—the underlying causes that lead to social failures. An explicit and detailed understanding of social failure modes, if properly applied in engineering design practice, could result in a fuller evaluation of the social and ethical implications of technology, either during the upstream design and engineering phases of a product, or after its release. Ideally, studying social failure modes will improve people’s ability to anticipate and reduce the rate or severity of undesirable social failures prior to releasing technology into the wild.

The Subject

The design requirement is a description of the desired solution to a problem. In engineering design, as in all other, a clear expression of a well-formulated design goal is vital for successful and efficient completion of the design task. The nature of the design requirement and the processes by which it is achieved have been the subject of a wide variety of research. The purpose of the paper is twofold. Firstly, it sets out to collate and discuss representative research in this area in order to give an overview of the current scope of the work. Secondly, it seeks to draw a comparison with the task of developing the design requirement for software and information systems and to initiate a discussion that considers to what extent the substantial body of research in software requirements engineering might help to give an understanding of the design requirement for the engineering design domain. A tentative characterization of the differences between the tasks in the two domains is presented, and representative papers from requirements engineering are used to suggest areas of overlap as a starting point for further investigation.

AbstractThis paper proposes a new approach for calculating the impulse response of room acoustics. Impulse response provides unique characterization of any discrete lineartime invariant (LTI) systems. We assume that the room is a linear time-invariant system and the impulse response is calculated simply by sending a Dirac Impulse into the system as input and getting the response from the output. Then, the output of the system is represented as a sum of time-shifted weighted impulse responses. Both mathematical justifications for the proposed method and results from simulation software developed to evaluate the proposed approach are presented in detail.

Learner’S Perspective

This study explores engineering design students’ perceptions of humor in the experiences of creativity development in Project-Organized Groups (pogs). This study links theories including humor, learning, creativity, and engineering design in one framework. Empirically, this study carried out interviews with a total of 13 students in engineering design education at Northeastern University (neu) in China. We found that students think all humorous people are creative, and they welcome humor in project groups; they also regard humor as not only a personality or communication tool, but also the outcome of applying creative ideas in design practice. The students additionally think that humor is mainly used to keep individuals’ harmonious relationship with the group and that humor is the immediate ability to create using language in ongoing communication contexts. These findings are helpful to unpack the black box of humor from a learner’s perspective and contribute to future joint efforts of studies on humor and creativity in engineering design education.
