An assessment of a unmanned aerial vehicle-based broadcast scenario assuming random terrestrial user locations
(2021)With the advent of the new decade, unmanned aerial vehicles (UAVs) will increasingly play an active role mainly as broadband transmission relays for broadcast applications. In the present study, we consider a feasible ... -
Buckling of thin-walled long steel cylinders under bending
(2010)The present paper investigates structural response and buckling of long unstiffened thin-walled cylindrical steel shells, subjected to bending moments, with particular emphasis on their stability design. The cylinder ... -
Buckling of unconfined and confined thin-walled steel cylinders under external pressure
(2008)The present paper investigates the structural stability of thin-walled steel cylinders subjected to uniform external pressure. A brief discussion of unconfined steel cylinder buckling is presented first. Subsequently, ... -
Cooperative Speed Estimation of an RF Jammer in Wireless Vehicular Networks
(2020)In this paper, we are concerned with the problem of estimating the speed of an RF jammer that moves towards a group/platoon of moving wireless communicating nodes. In our system model, the group of nodes receives an ... -
Critical review of pricing schemes in markets with non-convex costs
(2016)We consider a market in which suppliers with asymmetric capacities and asymmetric marginal and fixed costs compete to satisfy a deterministic and inelastic demand of a commodity in a single period. The suppliers bid their ... -
New results on turbulence modeling for free-space optical systems
(2010)In this paper, we propose a statistical channel model, named as Double-Weibull, to describe the irradiance fluctuations in moderate and strong turbulence for free-space optical (FSO) systems. The proposed stochastic model ... -
On the Average Harvested Energy of Directive Lightwave Power Transfer (DLPT)
(2021)We investigate the impact of the channel statistics on the average harvested energy when directive lightwave power transfer (DLPT) is used for both indoor and outdoor environments. More specifically, for the indoor scenario, ... -
On the inverse-Gaussian shadowing
(2011)The Inverse Gaussian (IG) distribution has been recently proposed as a less complex alternative to the classical log-normal distribution to describe shadowing phenomena. This paper investigates the performance of digital ...
