Min-Entropy Leakage of Channels in Cascade [PDF]
, 2012 Theories of quantitative information flow offer an attractive framework for analyzing confidentiality in practical systems, which often cannot avoid "small" leaks of confidential information. Recently there has been growing interest in the theory of min-entropy leakage, which measures uncertainty based on a random variable's vulnerability to being ...

End-to-End Physical Layer Authentication for Dual-Hop Wireless Networks
IEEE Access, 2019 End-to-end (E2E) physical layer authentication for multi-hop wireless networks is still not well-explored by now. Like one step forward in this direction, this paper focuses on the E2E physical layer authentication in a dual-hop wireless network with an ...

Thermal and exergetic analysis of Metal Foam-enhanced Cascaded Thermal Energy Storage (MF-CTES) [PDF]
, 2013 Metal Foam-enhanced Cascaded Thermal Energy Storage (MF-CTES) has been proposed to solve the problem of poor heat transfer during heat exchange process, which is caused by unavoidable decrease of temperature differences. This paper conducts a theoretical

Input polarization-independent multi-channel switching using cascaded long-period fiber grating and polarization-maintaining fiber [PDF]
, 2005 Novel multi-wavelength switching filters based on cascaded long-period fiber grating (LPG) and polarization-maintaining fiber (PMF) in a Sagnac loop configuration are proposed and experimentally demonstrated.

, 2018 The hierarchy of channel networks in landscapes displays features that are characteristic of non-equilibrium complex systems. Here we show that a sequence of increasingly complex ridge and valley networks is produced by a system of partial differential equations coupling landscape evolution dynamics with a specific catchment area equation.

A simplistic channel model for cascaded PLC-VLC systems [PDF]
, 2017 : In this a paper, we propose a simplistic channel model for cascaded PLC-VLC system which highlights the noise scenario in such hybrid systems. The model utilises previously proposed channel transfer functions of both PLC and VLC channels and highlights

Detection probability of passive RFID systems under cascaded Rician and Rayleigh fading channel [PDF]
, 2014 Radio Frequency Identification (RFID) system uses the principle of radiative power transfer between the reader and the tag antenna. The main performance metric for RFID system is the reliable reading coverage, where the tag can be read with higher ...

Path Loss Model for 3.5 GHz and 5.6 GHz Bands in Cascaded Tunnel Environments
Sensors, 2022 An important and typical scenario of radio propagation in a railway or subway tunnel environment is the cascaded straight and curved tunnel. In this paper, we propose a joint path loss model for cascaded tunnels at 3.5 GHz and 5.6 GHz frequency bands. By
