Context-Aware Beam Tracking for 5G mmWave V2I Communications

IEEE Transactions on Mobile Computing, 2023
Vehicles’ mobility causes frequent beam misalignments in millimeter wave (mmWave) vehicle-to-infrastructure (V2I) communications. In 5G systems, beam sweeping is done repeatedly to track a vehicle's mobility and maintain high-quality beam selection ...

Vehicle-to-infrastructure IEEE 802.11ad Wi-Fi dataset

Data in Brief, 2023
Despite not being designed for vehicular use, the high bandwidth offered by IEEE 802.11ad makes it an enticing proposition for opportunistic Vehicle-to-Infrastructure (V2I) communication.Because it operates at a high frequency of 60 GHz, 802.11ad suffers

Spatial Characterization of Radio Propagation Channel in Urban Vehicle-to-Infrastructure Environments to Support WSNs Deployment

Sensors, 2017
Vehicular ad hoc Networks (VANETs) enable vehicles to communicate with each other as well as with roadside units (RSUs). Although there is a significant research effort in radio channel modeling focused on vehicle-to-vehicle (V2V), not much work has been

Mesh Processing Non‐Meshes via Neural Displacement Fields

Computer Graphics Forum, EarlyView.
Abstract Mesh processing pipelines are mature, but adapting them to newer non‐mesh surface representations—which enable fast rendering with compact file size—requires costly meshing or transmitting bulky meshes, negating their core benefits for streaming applications.

A Deep Reinforcement Learning-Based Two-Dimensional Resource Allocation Technique for V2I Communications

IEEE Access, 2023
This paper proposes a two-dimensional resource allocation technique for vehicle-to-infrastructure (V2I) communications. Vehicular communications requires high data rates, low latency, and reliability simultaneously. The 3rd generation partnership project

Teacher Well‐Being Across Career Stages: An Ecological Study of Early‐ and Mid‐Career English Teachers in Japanese Secondary Schools

International Journal of Applied Linguistics, EarlyView.
ABSTRACT Teacher well‐being has garnered increasing attention in language education, as it plays a vital role in shaping both their professional lives and student learning. Although its importance is recognised, further research is still needed to gain a more comprehensive understanding of language teachers' well‐being.

Measuring Interactional Competence in a Japanese University EFL Speaking Context

International Journal of Applied Linguistics, EarlyView.
ABSTRACT The ability to interact is an integral aspect of speaking proficiency. Therefore, methods of assessing interaction need to be incorporated into second language (L2) speaking tests. The main purpose of this exploratory study is to attempt to quantify interactional competence (IC) in a Japanese university EFL (English as a foreign language ...
