 Review of a Multipurpose Duty-Cycle Modulation Technology in Electrical and Electronics Engineering
This paper presents a review of a multipurpose duty-cycle modulation (DCM) technology. A brief introduction to switching modulation techniques is presented for the sake of well understanding of the innovative nature of the DCM architecture to be reviewed. The review is organized into numerous relevant application areas, including DCM-based instrumentation systems (i.e., DCM-based analog-to-digital conversion, DCM-based digital-to-analog conversion), DCM-based power electronic drivers (i.e. DCM-based Buck converters, DCM-based Boost converters, DCM-based power electronic inverters), and DCM-based digital transmission systems for arbitrary waveforms. Furthermore, the state-of-art evaluation as well as new research opportunities about the multipurpose DCM technology, are provided in order to outline possible patentable DCM control systems, to be dedicated in the future to electrical and electronics engineering markets.
 Virtual reality learning environment for enhancing electronics engineering laboratory experience
Engineering laboratory courses have a significant role in building practical knowledge and enhancing the skills of the students. While working in electronics laboratories, students often operate complicated laboratory equipment and juggle through a set of multiple knobs and buttons to configure the equipment(s). It takes a lot of practice to master the skill of operating the laboratory equipment and it becomes difficult for students to operate the equipment without any prior experience. Virtual reality (VR) is the emerging technology and has the potential to provide a better learning experience to the students. In this paper, a VR‐based learning environment (VLE) is developed, which aims to give prior training to the engineering students about the electronics laboratory hardware. An experimental study was conducted to measure the effectiveness of VR on student knowledge development, learning motivation, and cognition. The study was conducted among the 65 engineering students and they were randomly divided into two groups: treatment group (N = 33) and control group (N = 32). The students of the treatment group were taught with the VR approach and students of the control group were taught with a conventional teaching approach. The outcomes of the experiment indicate that VR has a significant positive impact on student knowledge, learning motivation, and cognition. By interacting with the three‐dimensional virtual models of the laboratory instruments, students were able to demonstrate an improved understanding of the laboratory hardware.
 Perceptions of generic strategies of small and medium sized engineering and electronics manufacturers in the UK: The applicability of the Miles and Snow typology
To present the main findings of a study conducted in manufacturing firms in the UK to determine the applicability of generic strategies to small and medium sized firms (SMEs).
The Miles and Snow strategic orientation typology was used to examine the emphasis on the factors used to craft strategy and its subsequent impact on organizational performance. The study examined its applicability in two contrasting sectors: engineering and electronics.
Based on the responses obtained from 194 SMEs, the findings indicate that the main strategic orientation types present in this study are associated with different environment types; prospectors tend to perceive their environment as “dynamic” whereas defenders perceive their environment as “stable”. Distinct differences were found in relation to the emphasis of both orientation types on leadership, culture, strategy, and performance outcomes. Finally, the findings indicate that “prospectors” perform better than “defenders” and are twice as likely to be high performing. Smaller firms are more likely to be “prospectors” compared with firms employing over 100 staff.
The study confirms the applicability of the Miles and Snow typology to SMEs – a domain neglected in previous studies. The findings also depict the association between the attributes of the operating environment, organizational culture, leadership and strategy on both defenders and prospectors and the path to either high or low performance.
 Networks in engineering: an emerging approach to project organization studies
The field of social science has introduced a number of qualitative and quantitative approaches that have been adopted in the engineering project organization research domain. One such approach that is receiving increasing attention is social network analysis (SNA). Introduced in the 1930s and refined in multiple domains since the introduction, SNA has become a fundamental tool for social scientists over the past eight decades. Recently, engineering project organization researchers have begun to explore the application of this tool within the engineering project domain. This paper introduces both the historical development of SNA within the social science community and the recent adoption of this approach within the engineering community. The paper traces the recent trend in papers published by the engineering community to illustrate the increasing attention paid to SNA by researchers and the evolution of its use. This background is used to propose several paths forward for future researchers to expand and mature SNA research in the engineering project organization domain. The paper concludes with a charge to the research community to both widen the application of SNA within the domain and pursue a deeper understanding of its applicability within the field of engineering project organizations.
 Consideration of Innovating Cultivation Mode for Electronic Commerce Talents in China
Social and economic development is more and more inseparable from the electronic commerce. The e-commerce is widely applied in various industries. Development for the e-commerce leads to the talent demand, and Chinese universities supply a lot of e-commerce graduates to market every year. However, although e-commerce talents are still in a short supply in the market, the e-commerce graduates in Chinese colleges and universities encountera situation that they can’t find the suitable working position. The demanders always lack of talents and the suppliers always look for jobs on the market. This is derived from supply and demand dislocation for the talents. By analyzing the professional training objectives and cultivation mode, major background and technical requirements of the e-commerce, it is realized that there are lacks of a targeted market and lacks of practical guidance of enterprises in the training of the college e-commerce graduates. In this paper, based on the discussion of differences for both supply and demand sides in the ability of recognition and trust, the sources of the dislocation is analyzed and the author puts forward to solve to the supply and demand dislocation for the e-commerce talents based on the interaction of all the social parties.
