Patterned polymer films using soft lithography and micro molding in capillaries (MIMIC)
(2017-05)
This research work reports a low cost method to pattern large area surfaces using soft-lithographic approach through several polymers, particularly with the self-assembly of block co-polymers (BCPs) and also by fabricating ...
Adaptive OFDM-based acoustic underwater transmission: system design and experimental verification
(2017-08)
In this study, we design and implement an adaptive Underwater Acoustic (UWA) orthogonal frequency division multiplexing (OFDM) system employing adaptive modulation and transmit power. Recently, UWA communications gain more ...
Diversity techniques for ultraviolet communications
(2016-08)
Strong molecular and aerosol scattering in ultraviolet (UV) wavelengths enable mechanisms where transmitter can communicate with the receiver in the absence of line of sight (LOS) link. Recent advances in solid state ...
FOVLC: Foveation based data hiding in display transmitters for visible light communications
(2018-05)
Visible light communications is an emerging architecture with unlicensed and huge bandwidth resources, security, and experimental implementations and standardization e orts. Display based transmitter and camera based ...
Optimization and analysis of WLAN RF energy harvesting system architecture for low power wireless applications
(2017-01)
The presented work proposes a radio frequency (RF) energy harvesting circuit design, which scavenges energy from WLAN dual frequency band. In comparison to other available sources for energy scavenging, e.g. solar, wind ...
Vulnerability of speaker verification system under replay spoofing attack and investigation of synthetic speech detection
(2016-05)
Security issues have become major subject along with developments in the speaker verification system. Previous studies have shown that performance is still not fully proven for vulnerability. Simple and easy methods may ...
Performance analysis of vertical underwater visible light communication link
(2018-07)
Demand for high-bandwidth underwater applications such as image and real-time video transmission, has been increasing parallel to the increase in maritime activities such as environment monitoring, navigation, ocean-pollution ...
Modeling of RF energy harvesting and energy consumption system for low power wireless sensor networks
(2017-01)
Recently, with the advancement of technology, there has been a rapid growth of low power wireless devices, such as wireless sensor networks (WSNs) and Internet of Things (IoT). Therefore, the energy requirement for perpetual ...
A new LED driver design with CRM flyback topology and high power factor and low total harmonic distortion
(2018-01)
In many of today's solid-state lighting (SSL) applications, Critical Conduction Mode (CRM) Flyback PFC converter is a popular solution due to its limited component count and simple structure with respect to other switched ...
Energy consumption modeling and optimization of speed profile for plug-in electric vechiles
(2018-05)
In recent years, there is a surge in research on Plug-in Electric Vehicles (PEVs),
as PEVs are one of the ways that we can reduce carbon emissions. Dramatic cost
reduction in PEVs has resulted in their becoming mainstream ...
