Previous studies have shown and proven that employees need temporary detachment from their work to recharge re-energize for the next day with similar enthusiasm. But pressures overwork culture become a buzzword every corporate follows, are bound face it. This study investigates impact of (OWC) on employee longevity (EL). Further, it examines mediating role psychological (EPD) linkage between OW...

In this paper, the design of a multiple-input multiple-output (MIMO) optical wireless communication (OWC) link based on vertical cavity surface emitting laser (VCSEL) arrays is systematically carried out with aim to support data rates in excess 1 Tb/s for backhaul sixth generation (6G) indoor networks. The proposed combines direct current orthogonal frequency division multiplexing (DCO-OFDM) an...

Optical wireless communication (OWC) over atmospheric turbulence and pointing errors is a well-studied topic. Still, there limited research on signal fading due to random fog in an outdoor environment for terrestrial communications. In this paper, we analyze the performance of decode-and-forward (DF) relaying under combined effect fog, errors, with negligible line-of-sight (LOS) direct link. We...

and Applied Analysis 3 that w fw gw, that is, w is a common fixed point for f, g . If z is any common fixed point for f, g (i.e., fz gz z , then, again by the uniqueness of POC, it must be z w. The following result is due to Ðorić et al. [21]. It shows that the results of Jungck and Rhoades are not generalizations of results obtained from Lemma 2.1. Proposition 2.3 (see [21]). Let a pair of map...

The development of high-speed and high-brightness vertical-cavity surface-emitting lasers (VCSELs), which can serve as an efficient light source for optical wireless communication (OWC), play a crucial role in growth the next generation networks, e.g., 6 G satellite communications. In this work, by optimizing size Zn-diffusion oxide-relief apertures 850 nm VCSEL, we obtain record-high brightnes...

OFDM transmission in optical wireless channel is established via asymmetrically clipped optical OFDM (ACO-OFDM). Clipping is one of the simplest methods to reduce the high peak to average power ratio (PAPR). Clipping leads to additional in-band distortion and out-of band distortion. In this paper it is proposed to mitigate the clipping noise by iterative reconstruction based method and Channel ...
