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.

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.

Diversity Technique

Due to the increasing demand for low power communication in the field of remote control & monitoring, it is necessary to introduce a communication technique to meet the various QoS requirements even in an inferior radio channels. In order to ensure these QoS requirements, we propose a communication technique that applies the channel code, diversity scheme into power-efficient modulation. It makes the radio possible to dramatically improve BER by reducing the uncertainty due to fading channels. A core of proposed communication technique is to maximize the performance gain by adopting diversity technique and channel coding scheme. Diversity gain and channel coding gain further increase the performance difference (gain) between power-efficient modulation and conventional modulation, resulting in a signification BER improvement. By adapting the proposed communication technique it is expected to improve the usability of low-power radio according to the satisfaction of the various QoS requirements.

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 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.

Routing Optimization

A improved genetic algorithm is proposed to QoS routing optimization. By improving coding schemes, fitness function designs, selection schemes, crossover schemes and variations, the proposed method can effectively reduce computational complexity and improve coding accuracy. Simulations are carried out to compare our algorithm with the traditional genetic algorithms. Experimental results show that our algorithm converges quickly and is reliable. Hence, our method vastly outperforms the traditional algorithms.
