Integrating QKD in telecommunication networks

open access: yes, 2010
To date, QKD development has mostly focused in non-shared point-to-point links. Despite its limitations, this is the only technology commercially available today, and this makes it even more expensive and not easily deployable. The integration of QKD with the commercial network infrastructure would open the possibility of a scalable deployment and ...

A Survey of Phase Shifters for Microwave Phased Array Systems

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
ABSTRACT Phased Array Systems (PASs) are extensively used in radar and telecommunication systems for diverse applications, including military surveillance and wireless broadband communication. Besides, they are becoming increasingly indispensable in modern applications such as multi‐function phased array radars for weather monitoring and aircraft ...

Does Developing a Belief in One Conspiracy Theory Lead a Person to be More Likely to Believe in Others?

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT The monological belief system model suggests that—for at least a subset of people—developing a belief in one conspiracy theory will cause them to be more likely to believe in others. This model has been influential in the literature, but its core causal hypothesis has never been credibly tested.

Optimal deployment of indoor wireless local area networks

open access: yesNetworks, Volume 81, Issue 1, Page 23-50, January 2023., 2023
Abstract We present a two‐phase methodology to address the problem of optimally deploying indoor wireless local area networks. In the first phase, we use Helmholtz's equation to simulate electromagnetic fields in a typical environment such as an office floor.

Improving a constructive heuristic for the general routing problem

open access: yesNetworks, Volume 81, Issue 1, Page 93-106, January 2023., 2023
Abstract The general routing problem (GRP) is a fundamental 𝒩𝒫‐hard vehicle routing problem, first defined by Orloff in 1974. It contains as special cases the Chinese postman problem, the rural postman problem, the graphical TSP, and the Steiner TSP. We examine in detail a known constructive heuristic for the GRP, due to Christofides and others.
