Entropy Production and Heat Generation in Computational Processes
To make clear several issues relating with the thermodynamics of
computations, we perform a simulation of a binary device using a Langevin
equation. Based on our numerical results, we consider how to estimate
thermodynamic entropy of computational devices. We then argue against the
existence of the so-called residual entropy in frozen systems such as ice.Comment: 6 pages, 1 figure
Vehicle Communication using Secrecy Capacity
We address secure vehicle communication using secrecy capacity. In
particular, we research the relationship between secrecy capacity and various
types of parameters that determine secrecy capacity in the vehicular wireless
network. For example, we examine the relationship between vehicle speed and
secrecy capacity, the relationship between the response time and secrecy
capacity of an autonomous vehicle, and the relationship between transmission
power and secrecy capacity. In particular, the autonomous vehicle has set the
system modeling on the assumption that the speed of the vehicle is related to
the safety distance. We propose new vehicle communication to maintain a certain
level of secrecy capacity according to various parameters. As a result, we can
expect safer communication security of autonomous vehicles in 5G
communications.Comment: 17 Pages, 12 Figure
