Demystifying the Role of zk-SNARKs in Zcash
(2020)
Zero-knowledge proofs have always provided a clear solution when it comes to conveying information from a prover to a verifier or vice versa without revealing essential information about the process. Advancements ...
IoT Data Quality Assessment Framework using Adaptive Weighted Estimation Fusion
(2023)
Timely data quality assessment has been shown to be crucial for the development of IoT-based applications. Different IoT applications' varying data quality requirements pose a challenge, as each application requires a ...
Stacked-Patch MIMO Antenna for Dual-Plane Beamsteering
(2022)
This paper proposes a compact stacked-patch Multiple-Input Multiple-Output (MIMO) antenna with beamsteering in azimuth and elevation planes. The beamsteering is executed by controlling the phase shifts and amplitudes ...
Flexible Multimode-Based Beamforming MIMO Antenna
(2023)
This work proposes compact, flexible Multiple Input
Multiple Output (MIMO) antennas. The design principle is
based on the excitation of different orthogonal radiating modes
within the same antenna volume. Via phase ...
Digital pattern synthesis with a compact MIMO antenna of half-wavelength diameter
(2021)
The paper presents a compact multiport antenna, with beamforming capabilities and a realized gain of 4.31 dBi with the size of λ/2. The antenna allows digital beamforming with independent control over three parameters: ...
Gender Effects in Mobile Application Development.
(2020)
Growing interest in the impact of gender on technology includes concerns with regard to gender bias and its implication in the user experience. Past explorations of gender and design revealed significant differences between ...
Energy-Efficient Physical Layer Security for Wearable IoT Devices
(2023)
This work proposes an energy-efficient Directional
Modulation (DM) scheme for on-body Internet of Things (IoT)
devices. DM performance is tested using a 5-port stacked-patch
MIMO antenna under two scenarios: free space ...
Design of AI-based lane changing modules in connected and autonomous vehicles: a survey
(2022)
Lane changing is one of the complex driving tasks as it requires the vehicle to be aware of its highlydynamic surrounding environment, make decisions, and enact them in a timely manner. By exploiting both sensors and ...
Compact Stacked-Patch Antenna for Directional Modulation in Azimuth and Elevation Planes
(IEEE, 2022)
This work proposes a compact stacked-patch antenna capable of beamsteering in the vertical and horizontal directions. These characteristics are studied to realize directional modulation (DM) schemes in the vertical and ...
Compact MIMO Antenna for MUSIC-Based Angle of Arrival Estimation in Wrist-Worn Devices
(IEEE, 2022)
In this work, we propose a compact Multiple-Input Multiple-Output (MIMO) antenna for wrist-worn devices. The design is capable of unidirectional beamsteering across the entire horizontal plane, a property that is exploited ...
