An Intelligent System-on-a-Chip for a Real-Time Assessment of Fuel Consumption to Promote Eco-Driving
(MDPI, 2020-09-19)Pollution that originates from automobiles is a concern in the current world, not only because of global warming, but also due to the harmful effects on people’s health and lives. Despite regulations on exhaust gas emissions ... -
An intense narrow equatorial jet in Jupiter’s lower stratosphere observed by JWST
(Springer Nature, 2023-10-19)The atmosphere of Jupiter has east–west zonal jets that alternate as a function of latitude as tracked by cloud motions at tropospheric levels. Above and below the cold tropopause at ~100 mbar, the equatorial atmosphere ... -
An introduction to national biographical dictionaries renovation
(Miroslav Krleža Institute of Lexicography, 2021-04-19)The aim of this paper is to take part in the debate about the future of national biographies today. In this sense, we analyse national biographical dictionaries as instruments for the creation of national memory and as a ... -
An invariant magnetoimpedance elem ent for stray fields detection
(Elsevier, 2016)Magnetoimpedance sensitive element that consists of one FeNi[125 nm]/Cu[3 nm])3FeNi[125 nm]/Cu[500 nm]/(FeNi[125 nm]/Cu[3 nm])3/FeNi[125 nm] multilayered structure was designed for the magnetic field detection in the wide ... -
An isoperimetric-type inequality for electrostatic shell interactions for Dirac operators
(Springer Nature, 2015-10-17)Abstract: In this article we investigate spectral properties of the coupling H +Vλ, where H = −iα ·∇ +mβ is the free Dirac operator in R3 , m > 0 and Vλ is an electrostatic shell potential (which depends on a parameter ... -
An mHealth Workplace-Based “Sit Less, Move More” Program: Impact on Employees’ Sedentary and Physical Activity Patterns at Work and Away from Work
(MDPI, 2020-11-28)Background: Most workplace interventions that aim to reduce sedentary behaviour have 38 focused on employees’ sedentary patterns at-work but less have focused on understanding the 39 impact beyond working time. The aim of ... -
An observational study to assess the educational management of conflicts between young children in the Pikler-Lóczy educational approach. Implications in the early development of personality
(Taylor & Francis, 2023-06-11)Personality develops during early childhood (0–3 years). As early childhood education is becoming a generalized trend worldwide, this means that school or secondary socialization overlaps with family or primary socialization ... -
An observer-based vaccination control law for an SEIR epidemic model based on feedback linearization techniques for nonlinear systems
(Springer, 2012-09)This paper presents a vaccination strategy for fighting against the propagation of epidemic diseases. The disease propagation is described by an SEIR (susceptible plus infected plus infectious plus removed populations) ... -
An on-line VAD based on Multi-Normalisation Scoring (MNS) of observation likelihoods
(Elsevier Ltd., 2018-05-31)Voice activity detection (VAD) is an essential task in expert systems that rely on oral interfaces. The VAD module detects the presence of human speech and separates speech segments from silences and non-speech noises. The ... -
An ongoing review of speech emotion recognition
(Elsevier, 2023-04)User emotional status recognition is becoming a key feature in advanced Human Computer Interfaces (HCI). A key source of emotional information is the spoken expression, which may be part of the interaction between the human ... -
An Optical Fiber Bundle Sensor for Tip Clearance and Tip Timing Measurements in a Turbine Rig
(MDPI, 2013-06)When it comes to measuring blade-tip clearance or blade-tip timing in turbines, reflective intensity-modulated optical fiber sensors overcome several traditional limitations of capacitive, inductive or discharging probe ... -
An Original Tribometer to Analyze the Behavior of Abrasive Grains in the Grinding Process
(MDPI, 2018-07)Manufacturing of grinding wheels is continuously adapting to new industrial requirements. New abrasives and new wheel configurations, together with wheel wear control allow for grinding process optimization. However, the ... -
An Overground Robotic Gait Training Program for People With Multiple Sclerosis: A Protocol for a Randomized Clinical Trial
(Frontiers Media, 2020)Maintaining the ability to walk is one of the significant challenges in people with multiple sclerosis (MS) for keeping a good quality of life as the disease and the aging process progresses. Overground robotic (OR) wearable ... -
An Overview of Adipose Tissue ACE2 Modulation by Diet and Obesity. Potential Implications in COVID-19 Infection and Severity
(MDPI, 2021-07-26)The present review is aimed at analysing the current evidence concerning the potential modulation of obesity and/or diet in adipose tissue ACE2. Additionally, the potential implications of these effects on COVID-19 are ... -
