On admissible orders over closed subintervals of [0,1]
In this paper, we make some considerations about admissible orders on the set of closed subintervals of the unit interval I[0,1], i.e. linear orders that refine the product order on intervals. We propose a new way to ... -
On fuzzy implications derived from general overlap functions and their relation to other classes
There are distinct techniques to generate fuzzy implication functions. Despite most of them using the combination of associative aggregators and fuzzy negations, other connectives such as (general) overlap/grouping ... -
On some classes of directionally monotone functions
In this work we consider some classes of functions with relaxed monotonicity conditions generalizing some other given classes of fusion functions. In particular, directionally increasing aggregation functions (called also ... -
On some classes of nullnorms and h-pseudo homogeneity
Nullnorms are aggregation functions which generalize t-norms and t-conorms. For each nullnorm there exists an annihilator element such that, below it, the function behaves like a t-conorm, and, above it, like a t-norm. ... -
On the characterization of lithium-ion batteries under overtemperature and overcharge conditions: identification of abuse areas and experimental validation
Although lithium-ion batteries have gained considerable popularity in renewable energy and electric vehicle applications, their safety still remains a concern under certain voltage, temperature, or state of charge conditions. ... -
On the measurement of stability parameter over complex mountainous terrain
Atmospheric stability has a significant effect on wind shear and turbulence intensity, and these variables, in turn, have a direct impact on wind power production and loads on wind turbines. It is therefore important to ... -
On the performance of an ENZ-based sensor using transmission line theory and effective medium approach
In this paper we perform an in-depth theoretical studyofa sensing platform based on epsilon-near- zero (ENZ) metamaterials. The structure proposed for sensing is a narrow metallic waveguide channel. An equivalent circuit ... -
On the performance of the zoned fishnet metamaterial lens with positive and negative reference phase
In this letter, several converging fishnet metalenses are designed using both the zoning and reference phase techniques. They are engineered with a focal length of 1.5λ0 at the design frequency of 55 GHz (λ0 = 5.45 mm) at ... -
On the reduction of authoritative DNS cache timeouts: detection and implications for user privacy
The domain name system (DNS) is an Internet network service that is used by hosts to resolve IP addresses from symbolic names. This basic service has been attacked and abused many times, as it is one of the oldest and most ... -
An ontology-based system to avoid UAS flight conflicts and collisions in dense traffic scenarios
New Unmanned Aerial Systems (UAS) applications will increase air traffic densities in metropolitan regions. Collision avoidance systems (CAS) are a key component in integrating a high number of UAS into the airspace in a ... -
Open repository for the evaluation of ransomware detection tools
Crypto-ransomware is a type of malware that encrypts user files, deletes the original data, and asks for ransom to recover the hijacked documents. Several articles have presented detection techniques for this type of ... -
Operations research helps public health services managers planning resources in the COVID-19 crisis
This article presents the usefulness of operational research models tosupport the decision-making in management problems on the COVID-19 pandemic. The work describes a discrete event simulation model combined with population ... -
Optical fiber lasers assisted by microdrilled optical fiber tapers
In this Letter, we present an analysis of the backscattering generated in a microdrilled tapered fiber within a short-linear-cavity fiber laser. We propose and experimentally demonstrate a fiber cavity laser based on a ... -
Optical fiber sensors based on microstructured optical fibers to detect gases and volatile organic compounds: a review
Since the first publications related to microstructured optical fibers (MOFs), the development of optical fiber sensors (OFS) based on them has attracted the interest of many research groups because of the market niches ... -
Optical fiber vacuum sensor based on etched SMS structure and PDMS coating
In this work, an optical fiber vacuum sensor based on a single-mode multimode single-mode (SMS) structure coated with polydimethylsiloxane (PDMS) is studied. The SMS structure generates an interferometric pattern based on ... -
Optical fibre sensors using graphene-based materials: a review
Graphene and its derivatives have become the most explored materials since Novoselov and Geim (Nobel Prize winners for Physics in 2010) achieved its isolation in 2004. The exceptional properties of graphene have attracted ... -

Optical system based on multiplexed FBGs to monitor hand movements
This contribution reports the development and characterization of an optical system based on parallel Fiber Bragg Gratings (FBGs) to monitor the movements of the wrist and fingers of a hand. The system consisted of a ... -
Optical-microwave sensor for real-time measurement of water contamination in oil derivatives
This paper presents a novel microwave sensor using optical activation for measuring in real-time the water contamination in crude oil or its derivatives. The sensor is constructed from an end-coupled microstrip resonator that ... -
Optimal strain-gauge placement for mechanical load estimation in circular cross-section shafts
The customary electrical circuit configuration for estimating mechanical loads with strain gauges uses Wheatstone full- or half-bridges. For each mechanical load to be estimated, a dedicated bridge with two or four gauges has ...
