«Нескончаемый гуманизм», «природный» космопо­литизм

The article focuses on the symptomatic interpretation of some modern concepts that ap­peal to a cosmic order. Against the background of well-known “dark”, homeless systems proposed by such Western thinkers as Q. Meillassoux, K. Barad, D. Haraway, E. Thacker et al., trying to present pictures of a world “without us”, the author examines here anti-colonialist approaches that complement the conclusions of European and North American researchers in their own way. The author shows that the ideas of a direct connection be­tween a moral act and a cosmic order or humanity spilled throughout the cosmos, al­though it turns out that they cannot be considered as the basis for universal coexistence, can nevertheless act as an engine of practical communication. With all fluctuations in the terminology that they use, in which the interchangeability of cosmopolitanism, cos­mology and space is not uncommon, combined with attempts to maintain the specificity of the “local”, it seems that these different works obviously tend to construct a new spe­cial type of statement.

Blockchain Systems, Technologies, and Applications: A Methodology Perspective

In the past decade, blockchain has shown a promising vision to build trust without any powerful third party in a secure, decentralized and scalable manner. However, due to the wide application and future development from cryptocurrency to the Internet of Things, blockchain is an extremely complex system enabling integration with mathematics, computer science, communication and network engineering, etc. By revealing the intrinsic relationship between blockchain and communication, networking and computing from a methodological perspective, it provided a view to the challenge that engineers, experts and researchers hardly fully understand the blockchain process in a systematic view from top to bottom. In this article we first introduce how blockchain works, the research activities and challenges, and illustrate the roadmap involving the classic methodologies with typical blockchain use cases and topics. Second, in blockchain systems, how to adopt stochastic process, game theory, optimization theory, and machine learning to study the blockchain running processes and design the blockchain protocols/algorithms are discussed in details. Moreover, the advantages and limitations using these methods are also summarized as the guide of future work to be further considered. Finally, some remaining problems from technical, commercial and political views are discussed as the open issues. The main findings of this article will provide a survey from a methodological perspective to study theoretical model for blockchain fundamentals understanding, design network service for blockchain-based mechanisms and algorithms, as well as apply blockchain for the Internet of Things, etc.

Enabling Precision Medicine via Contemporary and Future Communication Technologies: A Survey

Precision medicine (PM) is an innovative medical approach that considers differences in the individuals’ omics, medical histories, lifestyles, and environmental information in treating diseases. To fully achieve the envisaged gains of PM, various contemporary and future technologies have to be employed, among which are nanotechnology, sensor network, big data, and artificial intelligence. These technologies and other applications require a communication network that will enable them to work in tandem for the benefit of PM. Hence, communication technology serves as the nervous system of PM, without which the entire system collapses. Therefore, it is essential to explore and determine the candidate communication technology requirements that can guarantee the envisioned gains of PM. To the best of our knowledge, no work exploring how communication technology directly impacts the development and deployment of PM solutions exists. This survey paper is designed to stimulate discussions on PM from the communication engineering perspective. We introduce the fundamentals of PM and the demands in terms of quality of service that each of the enabling technologies of PM places on the communication network. We explore the information in the literature to suggest the ideal metric values of the key performance indicators for the implementation of the different components of PM. The comparative analysis of the suitability of the contemporary and future communication technologies for PM implementation is discussed. Finally, some open research challenges for the candidate communication technologies that will enable the full implementation of PM solutions are highlighted.

A review/survey paper on Nanobots in Medical Applications for brain tumor detections

This study is a review or survey on the use of nanobots in medicine. Designing and creating tiny machines, particularly robotic machines, is the field of nanorobotics. Any "smart" structure that is able to act, sense, signal, process information, think, manipulate, and exhibit swarm behaviour at the nanoscale is a nanorobot (10-9m). More specifically, the term "nanorobotics" (as opposed to "micro robotics") refers to the engineering field of nanotechnology that focuses on designing and creating nanorobots with devices that range in size from 0.1 to 10 micrometres and are made of components that are either nanoscale or molecular. Nanomedicine is one of the first practical applications of nanotechnology. Cancer cells are recognised and eliminated using biological devices. The project shown here was undertaken by an electronics and communication engineering post-graduate student in the department's second year at Bangalore's Dayananda Sagar College of Engineering. It was completed as part of the course requirements.

The Unreasonable Effectiveness of the Chaotic Tent Map in Engineering Applications

From decimal expansion of real numbers to complex behaviour in physical, biological and human-made systems, deterministic chaos is ubiquitous. One of the simplest examples of a nonlinear dynamical system that exhibits chaos is the well known 1-dimensional piecewise linear Tent map. The Tent map (and their skewed cousins) are instances of a larger family of maps namely Generalized Luröth Series (GLS) which are studied for their rich number theoretic and ergodic properties. In this work, we discuss the unreasonable effectiveness of the Tent map and their generalizations (GLS maps) in a number of applications in electronics, communication and computer engineering. To list a few of these applications: (a) GLS-coding: a lossless data compression algorithm for i.i.d sources is Shannon optimal and is in fact a generalization of the popular Arithmetic Coding algorithm used in the image compression standard JPEG2000; (b) GLS maps are used as neurons in the recently proposed Neurochaos Learning architecture which delivers state-of-the-art performance in classification tasks; (c) GLS maps are ideal candidates for chaos-based computing since they can simulate XOR, NAND and other gates and for dense storage of information for efficient search and retrieval; (d) Noise-resistant versions of GLS maps are useful for signal multiplexing in the presence of noise and error detection; (e) GLS maps are shown to be useful in a number of cryptographic protocols - for joint compression and encryption and also for generating pseudo-random numbers. The unique properties and rich features of the Tent Map (GLS maps) that enable these wide variety of engineering applications will be investigated. A list of open problems are indicated as well.

Optical fiber communication is of great importance in information transmission. Increasing the transmission capacity of optical fiber systems is a solution to meet the increasing demand for information, in which rare earth ion-doped fiber amplifiers play an important role. In this paper, the quasi-quadruple-energy structure of is equated and simplified to a conventional triple-energy structure to improve amplification's efficiency and significance. By exploring the influence of many factors on the praseodymium-doped fiber amplifier, the amplification band with gain window between 1250-1350nm is verified, and the amplification of the central wavelength of 1310nm is realized. It provides a theoretical reference for the subsequent application of praseodymium-doped fiber amplifiers in communication engineering, laser amplification and other fields. Since the amplification band of praseodymium-doped fiber amplifier matches the zero dispersion point of 6.652 optical fiber, it will have a huge application market in the 1310nm optical communication system.
