This paper proposes a new hybrid orthogonal frequency division multiplexing (OFDM) form termed as DC-biased pulse amplitude modulated optical OFDM (DPO-OFDM) by combining the ideas of existing (DCO-OFDM) and discrete multitone (PAM-DMT). The analysis indicates that required DC-bias for DPO-OFDM-based light fidelity (LiFi) depends on dimming level components DPO-OFDM. bit error rate (BER) perfor...

In this article, different forms of optical orthogonal frequency division multiplexing (OFDM) were observed which suitable for camera communication (OCC) systems. This research aims to establish the bit error rate (BER) versus signal-to-noise ratio (SNR) OCC system. will focus on systems and design that produces noise clipping but gain SNR as a whole if an optimum factor is chosen. The BER anal...

This study is designed to investigate the clinical application value of damage control orthopaedics (DCO) concept in guiding treatment severe traumatic fractures with massive hemorrhage. Using introduction DCO hospital June 2021 as cut-off point, patients and major bleeding admitted two periods before (January 2021~May 2021) after (June 2021~January 2022) were included group (n = 39) observatio...

To the Editor: Le Manach et al. present a study demonstrating the experimental applicability of changes in pulse pressure variation (dPPV) for the prediction of changes in cardiac output (dCO). The study is accompanied by a panegyric editorial answering the rhetorical question whether we need to monitor CO during surgery with a resounding NO! We now have dPPV!1,2 There is, however, a number of ...

Fog computing is a decentralized infrastructure that extends the capabilities of cloud closer to edge network. In fog network (FCN), resources, such as processing power, storage, and networking, are distributed at various points in network, including devices, nodes (FNs) access points, gateways, local servers. This architecture allows resource-limited end devices offload part their computationa...
