Outage performance of mixed RF-FSO systems over DGG and nakagami-m channels
(IEEE, 2020-12)In mixed RF (radio frequency)-FSO (free space optical) systems, the FSO link is used for backhauling while RF is used for wireless access. In many practical deployment scenarios especially in urban environments, more than ... -
Outage performance of multi-hop hybrid FSO/RF communication systems
(IEEE, 2015)In this paper, five scenarios are considered for the realization of a multi-hop hybrid free-space optical/radio frequency (FSO/RF) communication system with decode-and-forward (DF) relaying, and analytical outage probability ... -
Outage probability analysis of a vertical underwater wireless optical link subject to oceanic turbulence and pointing errors
(Optica Publishing Group, 2022-06-01)The reliability of an underwater wireless optical communication (UWOC) network is seriously impacted by beam misalignment between transmitters (Txs) and receivers (Rxs). Also, the performance of UWOC systems can be affected ... -
Outpatient appointment scheduling in presence of seasonal walk-ins
(Springer Nature, 2014-04)This study investigates appointment systems (AS), as combinations of access rules and appointment-scheduling rules, explicitly designed for dealing with walk-in seasonality. In terms of 'access rules', strategies are tested ... -
Output domain downscaler
(ISCIS 2016: Computer and Information Sciences, 2016)This paper offers an area-efficient video downscaler hardware architecture, which we call Output Domain Downscaler (ODD). ODD is demonstrated through an implementation of the bilinear interpolation method combined with ... -
The overall odds ratio as an intuitive effect size index for multiple logistic regression: examination of further refinements
(Sage, 2012-12)This study used Monte Carlo simulation to examine the properties of the overall odds ratio (OOR), which was recently introduced as an index for overall effect size in multiple logistic regression. It was found that the OOR ... -
Overcharging dilaton black holes in (2+1) dimensions to extremality and beyond
(World Scientific Publishing Co Pte Lt, 2020-12)We test whether static charged dilaton black holes in (2 + 1) dimensions can be turned into naked singularities by sending in test particles from infinity. We derive that overcharging is possible and generic for both ... -
Overspinning Kerr-MOG black holes by test fields and the third law of black hole dynamics
(Springer Nature, 2020-01-11)We evaluate the validity of the weak form of the cosmic censorship conjecture and the third law of black hole dynamics for Kerr-MOG black holes interacting with test scalar fields. Ignoring backreaction effects, we first ... -
Overview of light, plasmonics, and particles
(Elsevier, 2023-01-01)In this chapter, we present a short discussion about light and its importance in nature, human civilizations, and society, and provide some cultural discussions. We briefly mention the interconnections between electromagnetic ... -
The oxymoron of perpetual temporary protection: Syrians in Turkey
(Red de Revistas Científicas de América Latina y el Caribe, 2016)The crisis in Syria has entered its fifth year, becoming a protracted conflict in international conflict terminology. Based on figures compiled by the United Nations High Commissioner for Refugees (UNHCR), as of March 16, ...
