Convergence to real-time decision making

James M. TIEN

Frontiers of Engineering Management 2020, Volume 7, Issue 2, Pages 204-222 doi: 10.1007/s42524-019-0040-5

Abstract: Real-time decision making reflects the convergence of several digital technologies, including those concerned with the promulgation of artificial intelligence and other advanced technologies that underpin real-time actions. More specifically, real-time decision making can be depicted in terms of three converging dimensions: Internet of Things, decision making, and real-time. The Internet of Things include tangible goods, intangible services, ServGoods, and connected ServGoods. Decision making includes model-based analytics (since before 1990), information-based Big Data (since 1990), and training-based artificial intelligence (since 2000), and it is bolstered by the evolving real-time technologies of sensing (i.e., capturing streaming data), processing (i.e., applying real-time analytics), reacting (i.e., making decisions in real-time), and learning (i.e., employing deep neural networks). Real-time includes mobile networks, autonomous vehicles, and artificial general intelligence. Central to decision making, especially real-time decision making, is the ServGood concept, which the author introduced in an earlier paper (2012). It is a physical product or good encased by a services layer that renders the good more adaptable and smarter for a specific purpose or use. Addition of another communication sensors layer could further enhance its smartness and adaptiveness. Such connected ServGoods constitute a solid foundation for the advanced products of tomorrow which can further display their growing intelligence through real-time decisions.

An Adaptive Demodulation Method for BPSK Signals

Li Yanxin,Hu Aiqun,Song Yubo

Strategic Study of CAE 2006, Volume 8, Issue 5, Pages 49-51

Abstract:

The paper presents a novel method for demodulating the binary phase shift keying (BPSK) signals basing on adaptive filtering. The commonly used least mean square (LMS) error adaptive filtering algorithm is employed for studying the demodulating procedure and the performance of the novel adaptive BPSK demodulation. The novel adaptive BPSK demodulation does not need the adaptive filter completing convergence. The performance of the method in theory is compared with computer simulating results. It shows that the error rates in simulation agree well with that in theory. Also, it is indicated that the demodulation method has many advantages over conventional ones, such as the powerful anti-noise ability, the small transfer delay, and the convenient implementation with DSP technology, and has lower error rates than correlation modulation at the same sample rate.

Development Strategy for Polar Equipment in China

Yu Liwei, Wang Junrong, Wang Shuqing, Li Huajun

Strategic Study of CAE 2020, Volume 22, Issue 6, Pages 84-93 doi: 10.15302/J-SSCAE-2020.06.011

Abstract:

The polar regions are now becoming strategically important. The exploitation of polar resources is becoming the focus of international community’s attention. Polar equipment is the guarantee for humans to scientifically understand and sustainably exploit the polar resources; they primarily include equipment for scientific observation, navigation, and oil and gas exploitation in the polar regions. This study first summarizes the development of polar equipment in various countries, and the development status and problems of the polar equipment in China. Then, it analyzes the development trend and key technologies of polar equipment. China does not possess sufficient polar scientific equipment and its under-ice observation capacity is not strong. China also lacks the capacities for building polar vessels and the research and design capacities for polar resource development equipment. To promote the development of polar equipment by 2035, China should promote the Arctic environment observation, communication, and navigation technologies, make breakthroughs in key technologies regarding polar vessels, and develop key equipment for polar resource exploration, hoping to support the commercial development of the polar summer routes for the second half of the 21st century.

Empirical study on directional millimeter-wave propagation in vehicle-to-infrastructure communications

Xichen Liu, Lin Yang, Daizhong Yu,362475709@qq.com,eelyang@uestc.edu.cn,15908107465@163.com

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 4, Pages 503-516 doi: 10.1631/FITEE.2000464

Abstract: With the increased demand for unmanned driving technology and big-data transmission between vehicles, (mmWave) technology, due to its characteristics of large bandwidth and low latency, is considered to be the key technology in future vehicular communication systems. Different from traditional cellular communication, the vehicular communication environment has the characteristics of long distance and high moving speed. However, the existing communication channel tests mostly select low-speed and small-range communication scenarios for testing. The test results are insufficient to provide good data support for the existing vehicular communication research; therefore, in this paper, we carry out a large number of channel measurements in mmWave vehicle-to-infrastructure (V2I) long-distance communication scenarios in the 41 GHz band. We study the received signal strength (RSS) in detail and find that the vibration features of RSS can be best modeled by the modified considering road roughness. Based on the obtained RSS, a novel close-in (CI) model considering the effect of the transmitter (TX) and receiver (RX) antenna heights (CI-TRH model) is developed. As for the channel characteristics, the distribution of the root-mean-square (RMS) delay spread is analyzed. We also extend the two-section exponential (PDP) model to a more general form so that the distance-dependent features of the mmWave channel can be better modeled. Furthermore, the variation in both RMS delay spread and PDP shape parameters with TX-RX distance is analyzed. Analysis results show that TX and RX antenna heights have an effect on large-scale fading. Our modified , CI-TRH model, and two-section exponential PDP model are proved to be effective.
