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 ... -
Quantum interference in Wilkinson power dividers
Scaling up quantum technologies entails the challenge of developing large-scale and high-performance photonic quantum networks. Engineering novel optical components, with a compact footprint and advanced functionalities, ... -
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. ... -
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 ... -
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 ... -

Relevance of sex, age and gait kinematics when predicting fall-risk and mortality in older adults
Approximately one-third of elderly people fall each year with severe consequences, including death. The aim of this study was to identify the most relevant features to be considered to maximize the accuracy of a logistic ... -
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 ... -

Revealing the underlying mechanisms behind TE extraordinary THz transmission
Transmission through seemingly opaque surfaces, so-called extraordinary transmission, provides an exciting plat- form for strong light–matter interaction, spectroscopy, optical trapping, and color filtering. Much ofthe ... -
A review of IoT sensing applications and challenges using RFID and wireless sensor networks
Radio frequency identification (RFID) and wireless sensors networks (WSNs) are two fundamental pillars that enable the Internet of Things (IoT). RFID systems are able to identify and track devices, whilst WSNs cooperate ... -
Review on unmanned aerial vehicle assisted sensor node localization in wireless networks: soft computing approaches
Node positioning or localization is a critical requisite for numerous position-based applications of wireless sensor network (WSN). Localization using the unmanned aerial vehicle (UAV) is preferred over localization using ... -
Ring cavity erbium-doped fiber for refractive index measurements
In this study, an interrogation system based on an erbium-doped fiber ring cavity for refractive index measurements is presented and experimentally demonstrated. This cavity ring includes a 1 × 3 coupler wherein one of the ... -
Robust active damping strategy for DFIG wind turbines
Doubly fed induction generators (DFIGs) with an LCL filter are widely used for wind power generation. In these energy conversion systems, there is an interaction between the grid-side converter (GSC) and the rotor-side ...
