Power Efficient Scheduling and Hybrid Precoding for Time Modulated Arrays
(Institute of Electrical and Electronics Engineers, 2020-01-22)
[Abstract] We consider power efficient scheduling and precoding solutions for multiantenna hybrid digital-analog transmission systems that use Time-Modulated Arrays (TMAs) in the analog domain. TMAs perform beamforming ...
Design and Empirical Validation of a LoRaWAN IoT Smart Irrigation System
(MDPI AG, 2020-04-21)
[Abstract]
In some parts of the world, climate change has led to periods of drought that require managing efficiently the scarce water and energy resources. This paper proposes an IoT smart irrigation system specifically ...
Impact of Time-Modulated Arrays on the BER of Linear Digital Modulations
(Taylor & Francis, 2015-08-21)
[Abstract] Time modulation provides a simple way to control the power radiation pattern of an antenna array. By appropriately selecting the parameters of a Time-Modulated Array (TMA) it is possible to obtain a reconfigurable ...
Visualizing the 3D Polar Power Patterns and Excitations of Planar Arrays with Matlab
(Institute of Electrical and Electronics Engineers, 2004-04)
[Abstrac] This paper discusses the use of Matlab to create three-dimensional polar plots of the power patterns of planar arrays together with 3D plots of the amplitudes and phases of their excitations. A few lines of Matlab ...
Near Field Quasi-Null Control with Far Field Sidelobe Level Maintenance in Line Source Difference Patterns
(Taylor & Francis, 2003)
[Abstract] A previously developed method to place a quasi-null in a specified angular position of the near-field line source in sum patterns while, simultaneously, the far-field sidelobe level is maintained under a desired ...
Green IoT and Edge AI as Key Technological Enablers for a Sustainable Digital Transition towards a Smart Circular Economy: An Industry 5.0 Use Case
(MDPI, 2021)
[Abstract] Internet of Things (IoT) can help to pave the way to the circular economy and to a more sustainable world by enabling the digitalization of many operations and processes, such as water distribution, preventive ...
Isolation Number versus Domination Number of Trees
(MDPI, 2021-06)
[Abstract] If 𝐺 = (Vɢ,Eɢ) is a graph of order n, we call 𝑆 ⊆ Vɢ an isolating set if the graph induced by Vɢ − Nɢ[𝑆] contains no edges. The minimum cardinality of an isolating set of 𝐺 is called the isolation number of ...
Architecture for Multi-Technology Real-Time Location Systems
(Multidisciplinary Digital Publishing Institute, 2013)
[Abstract]The rising popularity of location-based services has prompted considerable research in the field of indoor location systems. Since there is no single technology to support these systems, it is necessary to consider ...
Development of Recreational Content with Micro:Bit for Intervention with People with Cerebral Palsy
(MDPI, 2020-09-04)
[Abstract]
This paper presents a project carried out to use games in therapies for people with cerebral
palsy. A Micro:bit board is used to have a friendly interaction between the user and the game.
Through a simple ...
A Collaborative Augmented Reality Application for Training and Assistance during Shipbuilding Assembly Processes
(MDPI AG, 2020-08-18)
[Abstract]
This paper presents the development of a novel Microsoft HoloLens collaborative application that allows shipyard operators to interact with a virtual clutch during its assembly in a real Turbine workshop. Such ...
