Collinearly placed patch antenna arrays, printed on high permittivity dielectric substrates, suffer from an unwanted inter element coupling due to strong surface waves. A new shaped Defected Ground Structure (DGS) is proposed to suppress such waves in between elements. A low dimensional μ shaped DGS is carved out in between two E-plane patch antenn...
This paper discusses the comparison of two series–parallel hybrid electrical vehicles. The first one is based on the Toyota hybrid system, while the second one is equipped with an electrical variable transmission. The problem with previous comparisons between these two transmissions is the lack of validated data used to support the comparison as we...
In this paper, we propose, implement, and analyze the structures of two keyed hashfunctions using the Chaotic Neural Network (CNN). These structures are based on Spongeconstruction, and they produce two variants of hash value lengths, i.e., 256 and 512 bits. The firststructure is composed of two-layered CNN, while the second one is formed by one-la...
In this study, we made thetechnical qualification of borofloat 33 glassand also other much cheaper conventionalglasses, associated with solid metallizationby a broadband characterization methodbased on the S-parameters. This made itpossible to extract the electromagneticparameters (dielectric permittivity, tangentloss) necessary for the design andc...
A novel Distributed Galvanic Insulation (DGI) concept is presented in that paper. It implies a daisy chaining of the drivers. Applied to MMC, the DGI forbids the use of classical Voltage Balancing Algorithms. A new algorithm, directly integrated on the gate drivers, is proposed for DGI-MMC and validated by simulation.
The integration of computer-based technologies interacting with industrial machines or home appliances through an interconnected network, for teleoperation, workflow control, switching to autonomous mode, or collecting data automatically using a variety of sensors, is known as Internet of Things (IoT). When applied inside an industrial context, it ...
The present study, carried out within the framework of the PCC80 project (PCC80 stands for the Development of a New Generation of Condensing Boiler-Stove with recovery rate over 80 %), aims at investigating the possibility of combining a wood pellet boiler-stove (also called hydro pellet stove) together with other renewable (solar collector) and fo...
The COVID-19 pandemic has had a significant impact on the air transportation system worldwide. This paper aims at analyzing the effect of the travel restriction measures implemented during the COVID-19 pandemic from a passenger perspective on the US air transportation system. Four metrics based on data generated by passengers and airlines on social...
The Third Generation Partnership Project (3GPP) was established to bring together several standards organization to address the needs related to the specification of mobile broadband. Originally targeting the evolution from 2G to 3G, 3GPP continues at the forefront of the standardization effort leading to 5G and beyond. Given the growing diversity ...
The development of electric transport technologies is virtuous in many ways: electric motors have far better yields than combustion motors and contribute to decrease urban local pollution. However they present drawbacks in terms of energy supply. Thus the switch to electric motorization of part of the vehicle fleet leads to an increase in electrici...
