Although communication as a formal discipline is one of the youngest of the sciences, it has roots which extend back through the arts and philosophy at least as far back as the Greeks. Even today, Aristotle's rhetoric plays an important part in the training of many communication scholars. As a young and eclectic discipline, communication has drawn substance from many related fields and has dive...

Abstract A broadband plasmonic optical modulator based on a dual back-to-back U-shaped silicon waveguide and double layers of graphene has been investigated. The proposed structure is designed at TE mode over range wavelengths extending from 1.1 to 1.9 μm . By adjusting the geometry structure, modulator’s performance tuned. Utilizing propagation loss, bandwidth, power consumption, modulation de...

We conducted an experiment using a vibration system using which a totally deafblind participant, communicating through an interpreter, could directly receive back-channel feedback from a conversational partner. Statistical analysis of the interaction structure showed that the back-channel vibration increased the participant’s turn-taking ability and interactivity during the communication. Moreo...

In the last few years a lot of research has been carried out in the field of deliverance of information for improving its efficiency and reliability. However, the systematic analysis and verification of channel performance triggered wide interest of new researchers. The popular technique for transmission of signals over wireless channels was orthogonal frequency division multiplexing (OFDM). In...

This paper introduces a model of interaction between users and animated agents as well as inter-agent interaction that supports basic features of affective conversation. As essential requirements for animated agents’ capability to engage in and exhibit affective communication we motivate reasoning about emotion and emotion expression, personality, and social role awareness. The main contributio...

Target-to-user (T2U) association is a prerequisite to fully exploit the potential of sensing function in communication-centric integrated and communication (ISAC) systems, e.g., for beam blockage management. This letter proposes purposely mount RIS on roof vehicular user equipment (VUE), which can serve as an intentional back-reflector towards base station. By controlling reflection pattern ove...

The LoRa standard is currently widely employed for low-power long-range wireless sensor networks at sub-GHz frequency bands. longer wavelengths associated with technology provide excellent radiowave propagation characteristics, yielding a much larger coverage than the higher In case of wearable sensors, 868 MHz band can be covered by textile substrate-integrated-waveguide antennas convenient si...
