An Extensive Game-Based Resource Allocation for Securing D2D Underlay Communications
IEEE Access, 2019 Device-to-device (D2D) communication has been increasingly attractive due to its great potential to improve cellular communication performance. While resource allocation optimization for improving the spectrum efficiency is of interest in the D2D-related

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 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT English as a lingua franca (ELF) is increasingly used for communication in many EFL contexts, including Vietnam. Although Japan and Vietnam have a long history of economic cooperation, for practical reasons, English typically functions as the medium of communication between the two groups. This study examines Japanese expats who had studied or

On Maximum D2D Multiplexing in Asynchronous Communications [PDF]
2018 IEEE 87th Vehicular Technology Conference (VTC Spring), 2018 This paper studies two different multiplexing problems for Device to Device (D2D) asynchronous communications with different multi-carrier modulations. Several D2D pairs may be multiplexed on the same Resource Blocks (RB) if they are jointly able to reach a high Signal to Interference plus Noise Ratio (SINR).

Optimization of D2D emergency communication resources for UAV relay based on DA-STD3
EURASIP Journal on Wireless Communications and NetworkingThe allocation of communication resources is extremely important for the device-to-device (D2D) communication network with unmanned aerial vehicle (UAV) relays, but this field currently mainly focuses on the communication between UAVs and ground devices.

International Journal of Applied Linguistics, EarlyView.ABSTRACT Focusing on the narratives of two Japanese undergraduate students, this article examines their everyday experiences of using and learning English, situated within entangled relations of power. Drawing on the Foucauldian notion of discourse, the study reveals how multiple power/knowledge systems—such as native speakerism, prescriptivism ...
