60-GHz Millimeter-Wave Propagation Inside Bus: Measurement, Modeling, Simulation, and Performance Analysis
(Institute of Electrical and Electronics Engineers, 2019)[Abstract] Millimeter-wave (mmWave) transmission over the unlicensed 60-GHz spectrum is a potential solution to realize high-speed internet access, even inside mass transit vehicles. The solution involves communication ... -
A 120-second stretch improves postural control and plantar pressure: quasi-experimental study
(Associação Paulista de Medicina - APM, 2022-05)[Abstract] BACKGROUND: There are no studies on long-term bilateral calf stretching in relation to balance and plantar pressure. OBJECTIVES: To demonstrate that there is better control of posture and pressures after ... -
A 2D algorithm with asymmetric workload for the UPC conjugate gradient method
(Springer New York LLC, 2014)[Abstract] This paper examines four different strategies, each one with its own data distribution, for implementing the parallel conjugate gradient (CG) method and how they impact communication and overall performance. ... -
A 2D numerical model for the transport of pollutants. The influence of Boundary Conditions
(Utah State University Extension, 1999)[Abstract] The pollutants transport phenomena in a 2D unsteady free surface flow has been studied. The weighted residual method has been used for the integration of the transport equations, appying the Galerkin formulation ... -
A 2D numerical model using finite volume method for sediment transport in rivers
(2002)[Abstract] The study of rivers as ecosystems has many fields of research, like the resolution and comprehension of flow and sediment transport phenomena. In this communication a 2D numerical model using the Finite Volume ... -
A 3-biomarker 2-point-based risk stratification strategy in acute heart failure
(Frontiers, 2021-10-22)[Abstract] Introduction and Objectives: Most multi-biomarker strategies in acute heart failure (HF) have only measured biomarkers in a single-point time. This study aimed to evaluate the prognostic yielding of NT-proBNP, ... -
A 47-Year Comparison of Lower Body Muscular Power in Spanish Boys: A Short Report
(MDPI AG, 2020-08-20)[Abstract] Much of the evidence examining temporal trends in fitness among youth has found a decrease in measures of muscular strength and muscular power over recent decades. The aim of this study was to examine trends ... -
A 68 ka precipitation record from the hyperarid core of the Atacama Desert in northern Chile
(Elsevier, 2020-01)[Abstract] The Atacama Desert in northern Chile is one of the driest deserts on Earth. Hyperaridity persists at least since the Miocene and was punctuated by pluvial phases. However, very little is known about the timing, ... -

A aprendizaxe da música a través da relación da música culta da tradición Occidental e da música popular moderna e contemporánea: unha investigación etnográfica na educación secundaria post-obrigatoria
(2018)[Resumo] Esta investigación busca coñecer a configuración da ensinanza da música dentro da vía do Bacharelato de Artes Escénicas, Musicais e Danza, establecida dentro do marco lexislativo da LOE. Así, trátase de analisar ... -
A BEM approach for grounding grid computation
(Computational Mechanics Publications, 1994)[Abstract] Grounding systems are designed to preserve human safety and grant the integrity of equipments under fault conditions. To achieve these goals, the equivalent electrical resistance of the system must be low ... -
A BEM formulation for computational design of grounding systems in stratified soils
(Centro Internacional de Métodos Numéricos en Ingeniería, 1998)[Abstract] Substation grounding design involves computing the equivalent resistance of the earthing system -for reasons of equipment protection-, as well as distribution of potentials on the earth surface -for reasons of ... -
A benchmark problem with singularities for multibody system dynamics formulations with constraints
(Springer, 2023-04-19)[Abstract] When performing the numerical integration of multibody systems (MBS) dynamics, it is possible to choose from a wide variety of methods and implementations. Selecting the most appropriate option for a particular ... -
A Bi-Objective Scheduling Problem in a Home Care Business
(MDPI, 2021)[Abstract] In this work we study a routing and scheduling problem for a home care business. The problem is composed of two conflicting objectives, therefore we study it as a bi-objective one. We obtain the Pareto frontier ... -
A bike trips survey as an impetus for the transition to sustainable cities and societies
(Elsevier, 2023)[Abstract] This study aims to analyse the factors and strategies that condition the bicycle's use and highlight various unknown facts about the electric bicycle. To identify the brakes (examples: road safety, urban culture ... -
A Bio-inspired Hypoxia Sensor using HIF1a-Oxygen-Dependent Degradation Domain
(Nature, 2019-05-08)[Abstract] Functional imaging has become an important tool in oncology because it not only provides information about the size and localization of the tumour, but also about the pathophysiological features of the tumoural ... -
A Blended Artificial Intelligence Approach for Spectral Classification of Stars in Massive Astronomical Surveys
(MDPI AG, 2020-05-01)[Abstract] This paper analyzes and compares the sensitivity and suitability of several artificial intelligence techniques applied to the Morgan–Keenan (MK) system for the classification of stars. The MK system is based ... -
