Detecting Weak Signals of the Future: A System Implementation Based on Text Mining and Natural Language Processing

open access: yesSustainability, 2020
Organizations, companies and start-ups need to cope with constant changes on the market which are difficult to predict. Therefore, the development of new systems to detect significant future changes is vital to make correct decisions in an organization ...

Interpretation of weak backscattering signals in a weakly clouded atmosphere [PDF]

open access: yesE3S Web of Conferences, 2021
It is used here the lidar equation describing signals from a weakly turbid atmosphere to solve the problem of the determination of the atmospheric aerosol parameters.

New Approach of High Sensitivity Techniques Using Collective Detection Method with Multiple GNSS Receivers

open access: yesSensors, 2018
The Collective Detection (CD) technique is a promising approach to meet the requirements for signal acquisition in GNSS-harsh environments. The CD approach has been proposed because of its potential to operate as both a direct positioning method and a ...

A Fault Feature Extraction Method Based on Second-Order Coupled Step-Varying Stochastic Resonance for Rolling Bearings

open access: yesApplied Sciences, 2020
In mechanical equipment, rolling bearings analyze and monitor their fault based on their vibration signals. Vibration signals obtained are usually weak because the machine works in a noisy background that makes it very difficult to extract its feature ...

Identifying entrepreneurial discovery processes with weak and strong technology signals: a text mining approach [version 2; peer review: 2 approved]

open access: yesOpen Research Europe, 2022
This study aims to propose methods for identifying entrepreneurial discovery processes with weak/strong signals of technological changes and incorporating technology foresight in the design and planning of the Smart Specialization Strategy (S3). For this

Contextualising weak signals: Towards a relational theory of futures knowledge

open access: yesFutures, 2020
In this paper we propose a framework to re-think and widen the theoretical assumptions behind so-called weak signal theory in futures studies. This paper suggests that the present understanding of weak signals views the topic as a question of linear ...

Dibaryons with Strangeness: their Weak Nonleptonic Decay using SU(3) Symmetry and how to find them in Relativistic Heavy-Ion Collisions [PDF]

open access: yes, 2000
Weak SU(3) symmetry is successfully applied to the weak hadronic decay amplitudes of octet hyperons. Weak nonmesonic and mesonic decays of various dibaryons with strangeness, their dominant decay modes, and lifetimes are calculated.

Weak signals in the mobility landscape: car sharing in ten European cities [PDF]

open access: yesEPJ Data Science, 2019
Car sharing is one the pillars of a smart transportation infrastructure, as it is expected to reduce traffic congestion, parking demands and pollution in our cities.

Adaptive Stochastic Resonance Method Based on Quantum Genetic Algorithm and its Application in Dynamic Characteristic Identification of Bridge GNSS Monitoring Data

open access: yesIEEE Access, 2020
Bridge dynamic monitoring based on GNSS has become an important means of monitoring bridge structure. GNSS dynamic monitoring signals are often overwhelmed by strong noises and multipath errors.
