Quadcopter neural controller for take-off and landing in windy environments
(Elsevier, 2023) Artículo / ArtikuluaThis paper proposes the design of a quadcopter neural controller based on Reinforcement Learning (RL) for controlling the complete maneuvers of landing and take-off, even in variable windy conditions. To facilitate RL ... -
Quantum antenna arrays: the role of quantum interference on direction-dependent photon statistics
We investigate the role of quantum interference phenomena on the characteristics of the fields radiated by an array of quantum emitters. In analogy to, but distinct from, classical outcomes, we demonstrate that the array ... -
Quantum antireflection temporal coatings: quantum state frequency shifting and inhibited thermal noise amplification
The quantum optical response of antireflection temporal coatings (ATCs), that is, matching temporal layers that suppress the generation of backward waves in temporal boundaries, is investigated. The results reveal that ... -
Quasi-distributed vibration sensing based on weak reflectors and STFT demodulation
In this work, a new system is proposed for quasi-distributed vibration sensing based on the Doppler effect. The setup employs an optical frequency domain reflectometer (OFDR) and an array of weak reflectors. The short-time ... -
Quasi-distributed vibration sensing using OFDR and weak reflectors
The authors proposed a quasi-distributed vibration sensing technique using in-line weak reflectors and optical frequency domain reflectometry (OFDR). As a result, they achieved an 8 kHz measurable vibration frequency with ... -
A radio channel model for D2D communications blocked by single trees in forest environments
In this paper we consider the D2D (Device-to-Device) communication taking place between Wireless Sensor Networks (WSN) elements operating in vegetation environments in order to achieve the radio channel characterization ... -
Radio wave propagation and WSN deployment in complex utility tunnel environments
The significant growth of wireless communications systems in the last years has led to the adoption of a wide range of applications not only for the general public but, also, including utilities and administrative authorities. ... -
Random subwavelength structures on glass to improve photovoltaic module performance
Glass samples have been processed by a single-step self-masking RIE (Reactive Ion Etching) process to obtain random subwavelength structures (SWSs), which mimic anti-reflective and anti-soiling patterns present in nature. ... -
Ransomware early detection by the analysis of file sharing traffic
Crypto ransomware is a type of malware that locks access to user files by encrypting them and demands a ransom in order to obtain the decryption key. This type of malware has become a serious threat for most enterprises. ... -
Real time measuring system of multiple chemical parameters using microstructured optical fibers based sensors
In this paper, a multiplexing system for simultaneous interrogation of optical fiber sensors which measure different parameters is presented and validated. The whole system has been tested with 6 different sensing heads ... -
Real-time imaging with frequency scanning array antenna for industrial inspection applications at W band
A real-time imaging system based on a frequency scanning antenna for conveyor belt setups is presented in this paper. The frequency scanning antenna together with an inexpensive parabolic reflector operates at the W band ... -
Recent developments in fiber optics humidity sensors
A wide range of applications such as health, human comfort, agriculture, food processing and storage, and electronic manufacturing, among others, require fast and accurate measurement of humidity. Sensors based on optical ... -
Recycled granulates manufacturing from spent refractory wastes and magnesium based binder
This paper analyzes the ability of two Spent Refractory Wastes (SRW) for the manufacturing of recycled granulates for construction applications. A binary magnesium oxide and ground granulated blast furnace slag hydraulic ... -
Reduced loss and prevention of substrate modes with a novel Coplanar Waveguide based on Gap Waveguide technology
The Gap Waveguide technology utilizes an Artificial Magnetic Conductor (AMC) to prevent the propagation of electromagnetic (EM) waves under certain conditions, resulting in various gap waveguide configurations. In this ... -
Reduction of the size of L-fuzzy contexts. A tool for differential diagnoses of diseases
Information extraction from an L-fuzzy context becomes a hard problem when we work with a large set of objects and/or attributes. The goal of this paper is to present two different and complementary techniques to reduce ... -
Remote access protocols for Desktop-as-a-Service solutions
The use of remote desktop services on virtualized machines is a general trend to reduce the cost of desktop seats. Instead of assigning a physical machine with its operating system and software to each user, it is considerably ... -
