No. of bitstreams: 0 Previous issue date: 2021-01-01; 3D printing of components using a layer-based deposition of materials is referred to as additive manufacturing (AM). The ability to build complex geometry components, reduce waste and avoid assembly are the main advantages of this process. AM has been used in different industries like aerospace, medical...
5GMEDE-5G mobile edge computing with enriched radio network information services
Akman, A.; Monteiro, V.; Marques, P.; Rodriguez, J.; Vieira, Pedro; Marques, H.; Abdalla, A.5G has a number of challenges to solve. Higher data usage and processing power necessities have emerged from the increasing number of mobile users as well as mobile applications becoming more and more demanding. There is a significant need to reduce the latency of the mobile network while cutting down on energy consumption. Backhaul traffic needs to be optimized to avoid setting up costly backhaul connections. ...
Radio Resource Scheduling with Deep Pointer Networks and Reinforcement Learning
Al-Tam, Faroq; Mazayev, Andriy; Correia, Noélia; Rodriguez, J.This article presents an artificial intelligence (AI) adaptable solution to handle the radio resource scheduling (RRS) task in 5G networks. RRS is one of the core tasks in radio resource management (RRM) and aims to efficiently allocate frequency domain resources to users. The proposed solution is an advantage pointer critic (APC) deep reinforcement learning (DRL) agent. It is built with a deep pointer network ...
Adaptive spectrum allocation for 5G wireless communication scenarios
Correia, Noélia; Al-Tam, Faroq; Rodriguez, J.5G resources should be properly planned for users to have a good quality of service. This planning includes defining the most suitable numerology indexes and best spectrum allocation considering the requirements of current traffic, which may change over time. Furthermore, when accounting for changes in traffic pattern, any necessary reconfigurations should be minimized. Here in this article, an optimization mod...
Deep PC-MAC: a deep reinforcement learning pointer-critic media access protocol
Al-Tam, Faroq; Mazayev, Andriy; Correia, Noélia; Rodriguez, J.Developing artificial intelligence (AI) solutions for communication problems is one of the hottest topics nowadays. This article presents Deep PC-MAC, a novel deep reinforcement learning (DRL) solution to solve the fair coexistence problem (FCP) between heterogeneous nodes in the unlicensed bands. It is based on a hybrid architecture between pointer networks (Ptr-nets) and advantage actor-critic (A2C), i.e., po...

Modulation of magnetism and study of impedance and alternating current conducti...
Amor, S.B.; Benali, A.; Bejar, M.; Dhahri, E.; Khirouni, K.; Valente, M.A.; Graça, M.P.F.; Al-Turjman, F.; Rodriguez, J.; Radwan, A.A spinel ferrite sample Zn0.4Ni0.6Fe2O4 was prepared by a conventional solid-state reaction method at high temperature. This compound was found to exhibit a single phase and crystallize in a cubic structure with Pm3 m Space group. The complex impedance was investigated in the temperature range 400–700 K and in the frequency range 100 Hz - 1 MHz. The Z-impedance analysis revealed that the relaxation phenomenon i...
