(IEEE, 2020-10)Vehicular visible light communications (VLC) has emerged as a viable supplement for high speed next-generation vehicle to vehicle (V2V) communication systems. However, performance of a V2V-VLC link is impaired due to ... -
Low-complexity interference reduction for gfdm systems using corrective coefficients
(IEEE, 2022)Generalized Frequency Division Multiplexing (GFDM) is a promising multi-carrier modulation scheme for next-generation wireless communication systems. GFDM uses a non-orthogonal pulse shape, which leads to self-interference ... -
Low-cost thin-film passive RFID circuits and detector system
(Cambridge University Press, 2020-06)This paper discusses the design of chip-less RFID tags of a standard pocket size of 69 mm by 156 mm. These tags are based on lumped elements of copper metal traces constructed on a thin polyamide flexible substrate. Moreover, ... -
Low-cycle fatigue behavior of friction stir-welded copper joints
(Springer, 2021-11)Investigation of the fatigue response of friction stir-welded (FSWed) joints is especially important in the design and manufacturing of components with exposure to cyclic loading. In this study, cyclic response of FSWed ... -
Low-loss optical switch using Brewster angle
(IEEE, 2011)Fabrication and actuation errors of submicron silicon waveguide optical switches are reported to remain within sub-100 nm ranges. These errors cause high loss ruining the optical performance of the switches at the on-state. ... -
Lower uncertainty bounds of diffraction-based nanoparticle sizes
(Wiley, 2022-06)A self-consistent analysis is reported of traditional diffraction-based particle size determination techniques applied to synthetic diffraction profiles generated with the Patterson approach. The results show that dimensions ... -
Lump solutions of the fractional Kadomtsev–Petviashvili equation
(Springer, 2024-01)Of concern is the fractional Kadomtsev–Petviashvili (fKP) equation and its lump solution. As in the classical Kadomtsev–Petviashvili equation, the fKP equation comes in two versions: fKP-I (strong surface tension case) and ... -
Lyapunov-based model predictive control for stable operation of a 9-level crossover switches cell inverter in grid connection mode
(IEEE, 2023)This study proposes the application of a Lyapunov-based Model Predictive Control (L-MPC) approach to a 9-level Crossover Switches Cell (CSC9) converter operating in grid connection mode. The proposed method utilizes the ... -
MAC layer performance of multi-hop vehicular VLC networks with CSMA/CA
(IEEE, 2020)Majority of works in the field of vehicular visible light communication (VLC) networks are based on some ideal assumptions. Particularly, the ideal Lambertian pattern is assumed for channel modeling and only a simple ... -
