A uniform phase representation for the harmonic model in speech synthesis applications
(Springer International Publishing, 2014-10-16)
Feature-based vocoders, e.g., STRAIGHT, offer a way to manipulate the perceived characteristics of the speech signal in speech transformation and synthesis. For the harmonic model, which provide excellent perceived quality, ...
System architecture and deployment scenarios for SESAME: Small cEllS coordinAtion for Multi-tenancy and Edge services
(2016-05-17)
The surge of the Internet traffic with exabytes of data flowing over operators mobile networks has created the need to rethink the paradigms behind the design of the mobile network architecture. The inadequacy of the 4G ...
RESTful Discovery and Eventing for Service Provisioning in Assisted Living Environments
(MDPI, 2014-05)
Service provisioning in assisted living environments faces distinct challenges due to the heterogeneity of networks, access technology, and sensing/actuation devices in such an environment. Existing solutions, such as ...
Characterization of the Potential Effects of EMC Filters for Power Converters on Narrowband Power Line Communications
(MDPI, 2021-01-12)
Electromagnetic Compatibility (EMC) filters are one of the main solutions for dealing with the disturbances generated by power inverters. However, they show series/parallel resonances that introduce variations in the ...

(MDPI, 2021-09-06)
This paper proposes and studies the reachability of a singular regular dynamic discrete Leontief-type economic model which includes production industries, recycling industries, and non-renewable products in an integrated ...
Virtual PLC Lab Enabled Physical Layer Improvement Proposals for PRIME and G3-PLC Standards
(MDPI, 2020-03-04)
Narrowband (NB) powerline communication (PLC) is extensively adopted by utilities for the communication in advanced metering infrastructure (AMI) systems. PLC technology needs to overcome channel disturbances present in ...
Measurement of 2–150 kHz Conducted Emissions in Power Networks
(IEEE, 2021)
This article presents a comparison of measurement methods for current and voltage distortions in low-voltage networks in the frequency range from 2 to 150 kHz (supraharmonics). The comparison encompasses the methods ...
How to Survive Identity Management in the Industry 4.0 Era
(IEEE, 2021-07-06)
Industry 4.0 heavily builds on massive deployment of Industrial Internet of Things (IIoT) devices to monitor every aspect of the manufacturing processes. Since the data gathered by these devices impact the output of critical ...
Revisiting the Feasibility of Public Key Cryptography in Light of IIoT Communications
(MDPI, 2022-03-27)
Digital certificates are regarded as the most secure and scalable way of implementing authentication services in the Internet today. They are used by most popular security protocols, including Transport Layer Security (TLS) ...
