A Fog Computing and Cloudlet Based Augmented Reality System for the Industry 4.0 Shipyard
(MDPI AG, 2018)
[Abstract] Augmented Reality (AR) is one of the key technologies pointed out by Industry 4.0 as a tool for enhancing the next generation of automated and computerized factories. AR can also help shipbuilding operators, ...
A practical evaluation on RSA and ECC-based cipher suites for IoT high-security energy-efficient Fog and mist computing devices
(M D P I AG, 2018-11-10)
[Abstract] The latest Internet of Things (IoT) edge-centric architectures allow for unburdening higher layers from part of their computational and data processing requirements. In the specific case of fog computing systems, ...
Vehicle Classification using the Discrete Fourier Transform with Traffic Inductive Sensors
(Multidisciplinary Digital Publishing Institute, 2015)
[Abstract] Inductive Loop Detectors (ILDs) are the most commonly used sensors in traffic management systems. This paper shows that some spectral features extracted from the Fourier Transform (FT) of inductive signatures ...
SiDIVS: Simple Detection of Inductive Vehicle Signatures with a Multiplex Resonant Sensor
(Multidisciplinary Digital Publishing Institute, 2016)
This work provides a system capable of obtaining simultaneous inductive signatures of vehicles traveling on a roadway with minimal cost. Based on Time-Division Multiplexing (TDM) with multiple oscillators, one for each ...
Inductive loops for traffic control
(2015-09)
Inductive Loop Detectors (ILDs) are the most commonly used sensors in traffic management
systems. This work provides a system capable of obtaining simultaneous inductive
signatures of vehicles traveling on a roadway with ...
A fog computing based cyber-physical system for the automation of pipe-related tasks in the Industry 4.0 shipyard
(M D P I AG, 2018-06-17)
[Abstract] Pipes are one of the key elements in the construction of ships, which usually contain between 15,000 and 40,000 of them. This huge number, as well as the variety of processes that may be performed on a pipe, ...
Calculation of the Connected Dominating Set Considering Vertex Importance Metrics
(M D P I AG, 2018-01-28)
[Abstract] The computation of a set constituted by few vertices to define a virtual backbone supporting information interchange is a problem that arises in many areas when analysing networks of different natures, like ...
Hybrid Supervised-Unsupervised Channel Estimation Scheme with Dynamic Transmission of Pilots
(Springer, 2011-02)
[Abstract] Multiple-Input Multiple-Output (MIMO) digital communications standards typically include pilot symbols in the definition of the transmit signals with the purpose of acquiring the Channel State Information (CSI) ...
A Practical Evaluation of a High-Security Energy-Efficient Gateway for IoT Fog Computing Applications
(M D P I AG, 2017-08-29)
[Abstract] Fog computing extends cloud computing to the edge of a network enabling new Internet of Things (IoT) applications and services, which may involve critical data that require privacy and security. In an IoT fog ...
A low-cost decision-aided channel estimation method for Alamouti OSTBC
(Springer, 2013-11)
[Abstract] In wireless communication systems, channel state information (CSI) acquisition is typically performed at the receiver side every time a new frame is received, without taking into account whether it is really ...
