Secrecy performance of diffusion based molecular timing channels

open access: yesIET Communications, 2021
Motivated by the study of security issues in molecular communication, this paper addresses the problem of secure communication in a bio‐inspired field where confidentiality of the information is of significant importance. The new metrics are used for the

Probabilistic Modeling of Multicamera Interference for Time-of-Flight Sensors

open access: yesSensors, 2023
The behavior of multicamera interference in 3D images (e.g., depth maps), which is based on infrared (IR) light, is not well understood. In 3D images, when multicamera interference is present, there is an increase in the amount of zero-value pixels ...

On the Asymptotic Performance of Multiple Antenna Channels with Fast Channel Feedback

open access: yes, 2005
In this paper, we analyze the asymptotic performance of multiple antenna channels where the transmitter has either perfect or finite bit channel state information.

Preservation of information in a prebiotic package model [PDF]

open access: yes, 2007
The coexistence between different informational molecules has been the preferred mode to circumvent the limitation posed by imperfect replication on the amount of information stored by each of these molecules. Here we reexamine a classic package model in

Influence of different data densities on the mapping of agroclimatological parameters - case of precipitation

open access: yesActa Agriculturae Slovenica, 1998
Different spatial densities of precipitation data were used to illustrate the influence of data density on spatial information about this parameter. Four maps of long term precipitation data (1961-1990) for Slovenia were produced: on a base of all, half,

Lyapunov Drift-Plus-Penalty Based Resource Allocation in IRS-Assisted Wireless Networks with RF Energy Harvesting [PDF]

open access: yesRadioengineering, 2022
We propose a resource allocation policy for intelligent reflective surface (IRS)-assisted wireless powered communication network (WPCN) where the energy harvesting (EH) users (EHUs) have finite energy storage and data buffers, for storing the harvested ...

An empirical method to measure the relative efficiency of dairy producers using deterministic frontier analysis [PDF]

open access: yesManagement Science Letters, 2012
The purpose of this paper is to measure the relative efficiencies of various cow husbandries. The proposed model of this paper uses distribution free analysis to measure the performance of different units responsible for taking care of cows.
