A Survey on Internet of Vehicle (IoV): A pplications & Comparison of VANETs, IoV and SDN-IoV

The swift evolution of communication network technologies brings the smart connected objects into existence. The objects or things are connected and able to communicate with each other through Internet of Things (IoT). Internet of Vehicle (IoV) are the subset of the IoT technologies that has been implemented to the vehicle. IoV is the evolution of traditional Vehicular Adhoc Networks (VANETs) bringing new technologies to the smart connected vehicles. IoV network communication is purposedly to serve a real time data exchanged on roads between the vehicles and roads, vehicles and vehicles, vehicle and sensors, and vehicles and everything through different network technologies. There are significant differences between IoV, SDN-IoV and VANETs in term of network architecture, features, and applications that available. IoV and IoV-SDN is using different network framework giving different flexibility and scalability. In term of features and applications, IoV and IoV-SDN are having more wider and broad wireless connection technology in contrast with VANETs. In this survey paper, the survey will focus on the introduction to SDN, and differences of application and features in IoV, SDN-IoV and VANETs.

Evolution of Interpersona Communication Through Symbols (Sticker) Cyber Native In The Line App

The essence of man in life is to conduct communication activities. An individual is said to communicate with others if both have an understanding of the meaning of the message conveyed in his interaction. Advances in information communication technology provide opportunities for individuals to more easily interact over the internet. Of the recorded internet users, 130 million are active on social media. New Media Communication, or communication based on information technology, makes social media a prima donna for individuals to interact socially in cyberspace. Text-based communication platforms such as WhatsApp and LINE make it easier for individuals or those in cyberspace referred to as digital natives to interact. These digital natives in their interactions do the continuous thing as a habit that eventually becomes a culture of communication. In this research, the focus of research is the evolution of communication between users in the new media era in LINE users as a text application-based social media with a constructivist approach, qualitative research methodology with virtual ethnographic research methods and descriptive analysis levels. Data collection with online interviews, as well as chat history observations and the use of LINE sticker features. The purpose of the study is: (1) to find out the communication of digital natives on the LINE application platform, (2) to find out the evolution of interpersona communication formed from the results of native digital interactions on the LINE application platform using a virtual ethnographic approach.

The physics of people’s opinions

This paper explores the abstraction of classical physics and applies several metrics that explore the evolution of social opinion. These metrics include an abstraction of Newtonian kinematics: mass, position, speed, acceleration, and Newtonian dynamics, an abstraction of force. Poll data is fit to a 2nd-order polynomial and a logistic function. These fits are used to understand the acceleration of opinion shift, and we explore recent social, cultural, and environmental trends, such as views on global climate change. We compare our results with the evolution of communication technologies and time spent on devices over the past 120 years. We show that the model connects the evolution in opinion with an abstraction of a Galilean concept: acceleration is independent of mass. Finally, we discuss the model of social polarization and the non-linear effect of media such as echo chambers.

A High Gain, High BW OP AMP with Frequency Compensation Techniques at 65 nm Technology

OP-AMPs finds applications in different domains of electronics engineering including communications. There has been several OP-AMP configurations realized in the last decades for different target applications. But with the evolution of communication standards, to meet the demand for high data rate over the years, requirement for a high frequency and high BW OP-AMP is gaining attention. This makes the design challenge much higher. This paper presents a two-stage CMOS amplifier which uses frequency compensation method to facilitate higher BW. Different parameters like Gain, Gain band width product (GBWP), Phase Margin and Total Power dissipation are considered in this design. A step-by-step procedure for an efficient amplifier design is followed using frequency compensation. We have achieved a gain-bandwidth product (GBWP) of 110 MHz that is capable of driving large capacitive loads. It also achieves 77.7 dB gain with a phase margin of 60o.

Dominance style is a key predictor of vocal use and evolution across nonhuman primates

Animal communication has long been thought to be subject to pressures and constraints associated with social relationships. However, our understanding of how the nature and quality of social relationships relates to the use and evolution of communication is limited by a lack of directly comparable methods across multiple levels of analysis. Here, we analysed observational data from 111 wild groups belonging to 26 non-human primate species, to test how vocal communication relates to dominance style (the strictness with which a dominance hierarchy is enforced, ranging from ‘despotic’ to ‘tolerant’). At the individual-level, we found that dominant individuals who were more tolerant vocalized at a higher rate than their despotic counterparts. This indicates that tolerance within a relationship may place pressure on the dominant partner to communicate more during social interactions. At the species-level, however, despotic species exhibited a larger repertoire of hierarchy-related vocalizations than their tolerant counterparts. Findings suggest primate signals are used and evolve in tandem with the nature of interactions that characterize individuals' social relationships.

Multivariable Optimisation for Waiting-Time Minimisation at Roundabout Intersections in a Cyber-Physical Framework

The evolution of communication networks offers new possibilities for development in the automotive industry. Smart vehicles will benefit from the possibility of connecting with the infrastructure and from an extensive exchange of data between them. Furthermore, new control strategies can be developed that benefit the advantages of these communication networks. In this endeavour, the main purposes considered by the automotive industry and researchers from academia are defined by: (i) ensuring people’s safety; (ii) reducing the overall costs, and (iii) improving the traffic by maximising the fluidity. In this paper, a cyber-physical framework (CPF) to control the access of vehicles in roundabout intersections composed of two levels is proposed. Both levels correspond to the cyber part of the CPF, while the physical part is composed of the vehicles crossing the roundabout. The first level, i.e., the edge-computing layer, is based on an analytical solution that uses multivariable optimisation to minimise the waiting times of the vehicles entering a roundabout intersection and to ensure a safe crossing. The second level, i.e., the cloud-computing layer, stores information about the waiting times and trajectories of all the vehicles that cross the roundabout and uses them for long-term analysis and prediction. The simulated results show the efficacy of the proposed method, which can be easily implemented on an embedded device for real-time operation.

Airborne vocal communication in adult neotropical otters (Lontra longicaudis)

Most aquatic mammals have complex social and communication systems. Interestingly, little is known about otters’ vocal communication compared to other aquatic mammals. Here, for the first time, we acoustically describe vocalizations of the neotropical otter (Lontra longicaudis), a solitary and endangered New World otter species. We recorded vocalizations and behavioral contexts from six captive neotropical otters at Projeto Lontra, Santa Catarina Island, Brazil. Analysis of acoustic parameters were used to classify the vocalizations according to structure and context. We describe six call types with highly tonal as well as chaotic vocalizations with fundamental frequencies ranging from 90 to 2500 Hz. Additionally, we identified sex differences in the usage of calls. Results suggest that the neotropical river otter has a rich vocal repertoire, similar in complexity to other solitary otter species, but less complex than that of the social giant otter. Despite differences in sociality, phylogeny and ecology, L. longicaudis seems to possess vocalizations homologous to those found in other otters (e.g. hah and chirp), suggesting phylogenetic inertia in otter communicative repertoire. Otters thus offer an interesting but neglected group to explore the evolution of communication systems.

Structural Arrangements for Telecom Towers & Masts

Telecommunication is an important part of modern society. Nowadays, it may be clear to everyone that radio and television are of particular importance to broadcast news and information to all parts of the world, and have enormous cultural implications. With the use of technological development in the last few decades, the scope of operation and efficiency of these forms of mass media have increased daily. The facility of global coverage for transmitters has been enhanced with the use of satellites. In the meantime, it is essential to build ground transmitter antennas and construct metal and concrete towers & masts to install telecom antennas to transmit waves to conventional receivers.The design and build of telecom structures is a very specialised issue, which requires the cooperation of several specialists involved in such projects including telecom, structural, geotechnical engineers, and architects. These structures can be constructed as symbolic and landmark structures in urban areas or may be erected at the top of mountains.Undoubtedly the structural aspects of telecom towers and masts should play a significant role in the mind of the architect and designer. As a result, the realisation of all architectural ideas depends on structural assessment.How should these elegant and powerful structures, which represent the power and glory of human civilization, be constructed? What are the factors influencing their design and locations? What factors impact their effective height, and the answers to these questions and many others, have been examined in this book.The present book consists of 12 chapters and is in Persian. The evolution of communication technology is discussed in the first chapter. In the subsequent chapters of the book, the types of telecom structures, as well as the antenna array and radiation patterns, have been described concisely. Moreover, in Chapters 4, 5, and 6, the construction and the technical issues of the antennas, as well as the basic structures supporting them, have been discussed in detail. The fundamentals of the structural design of the telecom towers and masts have been explained in Chapters 9 and 10, and examples of a few existing towers and masts have been examined. At the end of the book, a glossary of antennas and related equipment has been added for the use of the readers.The 2nd edition of the book ‘Structural Arrangements for Telecom Towers & Masts’ was published by Noavar Publications in 2019.

Dynamic Analysis of Emergency Inter-organizational Communication Network under Public Health Emergency ： A case study of COVID-19 in Hubei Province of China

Public health emergencies, especially major infectious diseases, may cause global crises. Timely and effective communication is essential for response to such incidents. However, the emergency response to such incidents usually lasts longer and break out repeatedly, and the existing static emergency communication network (ECN) analysis cannot fully reflect the dynamic information interaction between organizations during the emergency process. Therefore, this article takes the recent COVID-19 epidemic in Hubei, China as a case, and uses social network analysis (SNA) to reveal the dynamic evolution of communication networks, organizational positions, roles, and organizational tasks from the time dimension. The results show that: (1) The ECN has changed from concentrated to decentralized over time; (2) The positions and roles of participating organizations in the ECN has changed, but there are still a few key organizations that at the central position in all phases of emergency communication; (3) The core tasks have changed due to emergency needs at each stage; (4) Under the concentrated management system, the core organization of the ECN mainly comes from government organizations. The research results reveal the dynamic evolution of communication networks between different types of emergency organizations, which is beneficial to guide emergency management of public health emergencies. In actual emergency, the emergency communication mode should be dynamically adjusted based on the characteristics of the emergency situation at different stages, comprehensively using the advantages of the concentrated and decentralized emergency network. In addition, communication between different types of organizations such as governments, research institutions, and enterprises should be strengthened, and channels for diversified organizations to participate in emergency communication should be set up. The research helps to improve communication between emergency response organizations and is of great significance to controlling and reducing the harm caused by public health emergencies.
