This study investigated processes in novice–expert consultation meetings in an organizational context to identify ‘what’ is done ‘how’ by novices and expert in consultation discourses. A conceptual model was developed for studying novice–expert design discourses at a fine-resolution level. An empirical study was performed at Rolls-Royce Aerospace Engineering. In total 7 audio-records were captured of meetings between trainees (novices) and expert designers, which occurred over the course of 3 trainee teams’ design projects. Relations were investigated between two coding schemes, namely the activity coding scheme and the conversational flow coding scheme. It was found that certain activities in the meeting were more often performed by either novices or experts, whereas other activities were more often performed collaboratively. Based on the results, implications for design engineering practitioners were derived and suggestions for further research are provided.

AbstractA 5G new radio cellular system is characterized by three main usage scenarios of enhanced mobile broadband (eMBB), ultra-reliable and low latency communications (URLLC), and massive machine type communications, which require improved throughput, latency, and reliability compared with a 4G system. This overview paper discusses key characteristics of 5G channel coding schemes which are mainly designed for the eMBB scenario as well as for partial support of the URLLC scenario focusing on low latency. Two capacity-achieving channel coding schemes of low-density parity-check (LDPC) codes and polar codes have been adopted for 5G where the former is for user data and the latter is for control information. As a coding scheme for data, 5G LDPC codes are designed to support high throughput, a variable code rate and length and hybrid automatic repeat request in addition to good error correcting capability. 5G polar codes, as a coding scheme for control, are designed to perform well with short block length while addressing a latency issue of successive cancellation decoding.

Design Experience

The design experience of 3rd year undergraduates in Mechanical Engineering at Ryerson University, and the assessment of student design work, was found to be disjointed and highly variable across the program. To attempt to address this, the authors are constructing courseware to help instructors of non-design engineering courses embed rich and consistent design projects into their courses. A “lightweight” Fast-Design process was developed. Course-specific design project examples of the process are being developed for five 3rd year courses using this design process. Current versions of all courseware are freely available. This paper details the nature of the courseware and how it was designed, developed,and deployed for the project. To date, one case has been deployed, two developed, and two more are under development. While results are so far only anecdotal, there is reason to believe that our approach can noticeably improve the design experience of students in non-design engineering courses.

AbstractThis article is a narrative inquiry of the lived spiritual experiences of students participating in Dalcroze Eurhythmics training. Previous studies have located Jaques-Dalcroze’s own writings and thought within the context of spirituality and have explored the spiritual experiences of Dalcroze teachers, but students’ perspectives remain to be investigated. We interviewed seven students, broadly defined as anyone currently attending regular Dalcroze training or who have recently attended Dalcroze courses and still consider themselves Dalcroze students. Various strategies for narrative data analysis were synthesised into our own coding scheme. Themes emerged from the data analysis: situation, continuity, personal interaction, social interaction and significant moments. The themes helped us construct a fictive conversation between the participants, using direct quotations from the interviews. Implications for practice focus on what inhibits and promotes experiences of spirituality in the Dalcroze class. This research will be relevant to music educators, as it gives clear, evidence-based guidelines on how opportunities for spirituality can be created in the Dalcroze classroom. It also offers an original synthesis of existing coding schemes for other researchers undertaking narrative inquiries.

This paper proposes a new bus-invert coding scheme for reducing the number of bus transitions. Unlike the previous schemes in which the entire bus lines or one subset of the bus lines are considered for bus-invert coding, in the proposed scheme, the bus lines are partitioned and each partitioned group is considered independently for bus-invert coding to maximize the effectiveness of reducing the total number of bus transitions. Experimental results show that the decomposed bus-invert coding scheme reduces the total number of bus transitions by 47.2% and 11.9% on average than those of the conventional and the partial bus-invert coding schemes respectively.

Industrial Needs

According to the Canadian Engineering Accreditation Board, all engineering programs in Canada must include a minimum of 15% of activities allocated to design. One can assume that these activities vary in content and scope between different programs. In this context, how can we define engineering design? Is there a recognized academic definition? Should our design goals be aligned with industrial needs and practice and if so, what should be the content of our design activities and how should they be structured? How is it possible to reach academic design goals given the limited resources available in our engineering schools? These are some of questions that will be addressed in this paper with the intent of better understanding the very important aspect of design’s engineering practice. Additional topics include: the change in design philosophy and approach resulting from a major program reform in the Mechanical Engineering Department at Université de Sherbrooke as well as the importance of industrial partnerships in design projects.

Special Case

We consider the primitive relay channel, where the source sends a message to the relay and to the destination, and the relay helps the communication by transmitting an additional message to the destination via a separate channel. Two well-known coding techniques have been introduced for this setting: decode-and-forward and compress-and-forward. In decode-and-forward, the relay completely decodes the message and sends some information to the destination; in compress-and-forward, the relay does not decode, and it sends a compressed version of the received signal to the destination using Wyner–Ziv coding. In this paper, we present a novel coding paradigm that provides an improved achievable rate for the primitive relay channel. The idea is to combine compress-and-forward and decode-and-forward via a chaining construction. We transmit over pairs of blocks: in the first block, we use compress-and-forward; and, in the second block, we use decode-and-forward. More specifically, in the first block, the relay does not decode, it compresses the received signal via Wyner–Ziv, and it sends only part of the compression to the destination. In the second block, the relay completely decodes the message, it sends some information to the destination, and it also sends the remaining part of the compression coming from the first block. By doing so, we are able to strictly outperform both compress-and-forward and decode-and-forward. Note that the proposed coding scheme can be implemented with polar codes. As such, it has the typical attractive properties of polar coding schemes, namely, quasi-linear encoding and decoding complexity, and error probability that decays at super-polynomial speed. As a running example, we take into account the special case of the erasure relay channel, and we provide a comparison between the rates achievable by our proposed scheme and the existing upper and lower bounds.

Virtual Product

As the inclusion of users in the design process receives greater attention, designers need to not only understand users, but also further cooperate with them. Therefore, engineering design education should also follow this trend, in order to enhance students’ ability to communicate and cooperate with users in the design practice. However, it is difficult to find users on teaching sites to cooperate with students because of time and budgetary constraints. With the development of artificial intelligence (AI) technology in recent years, chatbots may be the solution to finding specific users to participate in teaching. This study used Dialogflow and Google Assistant to build a system architecture, and applied methods of persona and semi-structured interviews to develop AI virtual product users. The system has a compound dialog mode (combining intent- and flow-based dialog modes), with which multiple chatbots can cooperate with students in the form of oral dialog. After four college students interacted with AI userbots, it was proven that this system can effectively participate in student design activities in the early stage of design. In the future, more AI userbots could be developed based on this system, according to different engineering design projects for engineering design teaching.

In this paper, we propose two feedback coding schemes for the action-dependent wiretap channel with noncausal state at the transmitter. The first scheme follows from the already existing secret key based feedback coding scheme for the wiretap channel. The second one follows from our recently proposed hybrid feedback scheme for the wiretap channel. We show that, for the action-dependent wiretap channel with noncausal state at the transmitter, the second feedback scheme performs better than the first one, and the capacity results of this paper are further explained via a Gaussian example, which we call the action-dependent dirty paper wiretap channel with noiseless feedback.
