Understanding the apparent superiority of over-sampling through an analysis of local information for class-imbalanced data
Elsevier (2020-11-15)Data plays a key role in the design of expert and intelligent systems and therefore, data preprocessing appears to be a critical step to produce high-quality data and build accurate machine learning models. Over the past ... -
Understanding the nesting spatial behaviour of gorillas in the Kagwene Sanctuary, Cameroon
Springer-Verlag (2012-08)We use spatial point pattern methods to analyse gorilla nest site data, and to enhance our understanding of the nesting behaviour of the Gorilla gorilla diehli in the Kagwene Sanctuary, Cameroon. Data were split into ... -
Understanding the sharing economy and its implication on sustainability in smart cities
Elsevier (2020-09-06)The purpose of this article is to evaluate the main drivers of the sharing economy through an exhaustive weighting and meta-analysis of previous relevant quantitative research articles, obtained using a systematic literature ... -
Unsupervised classification of children’s bodies using currents
Springer Verlag (2018-06)Object classification according to their shape and size is of key importance in many scientific fields. This work focuses on the case where the size and shape of an object is characterized by a current. A current is a ... -
Unsupervised colour image segmentation by low-level perceptual grouping
Springer (2013-11)This paper proposes a new unsupervised approach for colour image segmentation. A hierarchy of image partitions is created on the basis of a function that merges spatially connected regions according to primary perceptual ... -
Unsupervised Remote Sensing Image Retrieval Using Probabilistic Latent Semantic Hashing
Institute of Electrical and Electronics Engineers (2020-02-06)Unsupervised hashing methods have attracted considerable attention in large-scale remote sensing (RS) image retrieval, due to their capability for massive data processing with significantly reduced storage and computation. ... -
Unveiling fundamentals of multi-beam pulsed laser ablation in liquids toward scaling up nanoparticle production
MDPI (2024-02-16)Pulsed laser ablation in liquids (PLAL) is a versatile technique to produce high-purity colloidal nanoparticles. Despite considerable recent progress in increasing the productivity of the technique, there is still significant ... -
Upper bounds for the Poincaré recurrence time in quantum mixed states
IOP Publishing Ltd. (2017-04)In this paper we use geometric techniques to provide upper bounds for the Poincaré recurrence time of a quantum mixed state with a discrete spectrum of energies. We obtain two types of upper bounds. One of them depends on ... -
Using mobile devices as scientific measurement instruments: Reliable android task scheduling
Elsevier ScienceDirect (2022-01-29)In various usage scenarios, smartphones are used as measuring instruments to systematically and unobtrusively collect data measurements (e.g., sensor data, user activity, phone usage data). Unfortunately, in the race towards ... -
Using regression models for predicting the product quality in a tubing extrusion process
Springer (2018-05-01)Quality in a manufacturing process implies that the performance characteristics of the product and the process itself are designed to meet specific objectives. Thus, accurate quality prediction plays a principal role in ... -
Using SWE Standards for Ubiquitous Environmental Sensing: A Performance Analysis
MDPI AG (2012-08-31)Although smartphone applications represent the most typical data consumer tool from the citizen perspective in environmental applications, they can also be used for in-situ data collection and production in varied scenarios, ... -
Valley Hall phases in kagome lattices
American Physical Society (2019)We report the finding of the analogous valley Hall effect in phononic systems arising from mirror symmetry breaking, in addition to spatial inversion symmetry breaking. We study topological phases of plates and spring-mass ... -
