Velocity correlations in granular materials

, 1998
A system of inelastic hard disks in a thin pipe capped by hot walls is studied with the aim of investigating velocity correlations between particles. Two effects lead to such correlations: inelastic collisions help to build localized correlations, while ...

An Efficient V2I Authentication Scheme for VANETs [PDF]

Mobile Information Systems, 2018
The advent of intelligent transportation system has a crucial impact on the traffic safety and efficiency. To cope with security issues such as spoofing attack and forgery attack, many authentication schemes for vehicular ad hoc networks (VANETs) have been developed, which are based on the hypothesis that secret keys are kept perfectly secure. However,

An Efficient Cluster Based Resource Management Scheme and its Performance Analysis for V2X Networks

IEEE Access, 2020
As the demand for VANETs data transmission continues to increase, the defined cellular band becomes a bottleneck to meet the demands for all vehicle-to-everything (V2X) users.

microSlotted 1-Persistence Flooding in VANETs [PDF]

, 2009
Many Driver Support Systems in future vehicles will rely on wireless communication. This wireless communication can be divided into two categories: Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I).

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

Journal of Field Robotics, EarlyView.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Benchmarking 4G and 5G-Based Cellular-V2X for Vehicle-to-Infrastructure Communication and Urban Scenarios in Cooperative Intelligent Transportation Systems

Applied Sciences, 2022
Vehicle-to-Infrastructure (V2I) communication is expected to bring tremendous benefits in terms of increased road safety, improved traffic efficiency and decreased environmental impact. In 2017, The 3rd Generation Partnership Project (3GPP) released 3GPP

Distributed Hybridization Model for Quantum Critical Behavior in Magnetic Quasicrystals

, 2016
A quantum critical behavior of the magnetic susceptibility was observed in a quasicrystal containing ytterbium. At the same time, a mixed-valence feature of Yb ions was reported, which appears to be incompatible with the magnetic instability.

Performance Analysis of C-V2I-Based Automotive Collision Avoidance [PDF]

2018 IEEE 19th International Symposium on "A World of Wireless, Mobile and Multimedia Networks" (WoWMoM), 2018
One of the key applications envisioned for C-V2I (Cellular Vehicle-to-Infrastructure) networks pertains to safety on the road. Thanks to the exchange of Cooperative Awareness Messages (CAMs), vehicles and other road users (e.g., pedestrians) can advertise their position, heading and speed and sophisticated algorithms can detect potentially dangerous ...

Generation cycles in experimental populations of a multivoltine insect

Journal of Animal Ecology, EarlyView.
Although theory suggests various mechanisms by which environmental and ecological factors may drive generational fluctuations, our field‐cage experiment is the first to demonstrate how internal dynamics and external disturbances jointly produce synchronised, large‐scale outbreak cycles.

Modeling and Topological Properties of a V2I Sub Network in VANET Based on a Complex Network

Cybernetics and Information Technologies, 2015
Vehicles to Infrastructure (V2I) communicate with each other in a Vehicular Ad hoc NETwork (VANET) that can be represented as a complex network. In them much interest has been attracted towards the topological properties and structure recently, and many ...
