Numerical characterization of local and global non-uniformities in the load distribution in ball screws
(Springer, 2021)
Load distribution in ball screws is a representation of the ball contact stress, and it is fundamental to understanding the behavior of these machine elements. This work aims to conduct a multi-variable analysis of the ...
Clinical long-term nocturnal sleeping disturbances and excessive daytime sleepiness in Parkinson's disease
(PLOS, 2021)
Objective
To prospectively evaluate nocturnal sleep problems and excessive daytime sleepiness (EDS) in Parkinson’s disease (PD) patients, and analyze the influence of motor symptoms, treatment, and sex differences on sleep ...
A Model for Measuring and Managing the Impact of Design on the Organization: Insights from Four Companies
(MDPI, 2021)
Increasing numbers of companies are looking to embed design as a strategic capability to meet today’s business and social challenges. However, integrating design in an organization is a challenge, due to the scarcity of ...
The Positive Loop at Work: A Longitudinal Long-Term Study of Transformational Leadership, Group Passion, and Employee Result
(Frontiers Media S.A., 2021)
Positive psychology and positive organizational behavior studies recognize that leadership is extremely important for generating positive well-being. Despite the frequently reported significant positive correlations, the ...
Development, characterization and sterilisation of Nanocellulose-alginate-(hyaluronic acid)- bioinks and 3D bioprinted scaffolds for tissue engineering
(Elsevier, 2021)
3D-bioprinting is an emerging technology of high potential in tissue engineering (TE), since it shows effective control over scaffold fabrication and cell distribution. Biopolymers such as alginate (Alg), nanofibrillated ...
High magnetization FeCo nanoparticles for magnetorheological fluids with enhanced response
(Royal Society of Chemistry, 2021)
We present results concerning the fabrication of a new magnetorheological fluid with FeCo magnetic nanoparticles (NPs) as magnetic fillers. These NPs have been fabricated by using the chemical reduction technique and show ...
A Coloured Petri Net- and D* Lite-Based Traffic Controller for Automated Guided Vehicles
(MDPI, 2021)
Mobile robots, such as Automated Guided Vehicles (AGVs), are increasingly employed in automated manufacturing systems or automated warehouses. They are used for many kinds of applications, such as goods and material handling. ...
Review of computational parameter estimation methods for electrochemical models
(Elsevier Ltd, 2021)
Electrochemical models are an incipient technique for estimation of battery cells internal variables, useful for cells design or state of function optimization. One of the non-trivial procedures that allow the use of this ...
The effect of cross-section geometry on crushing behaviour of 3D printed continuous carbon fibre reinforced polyamide profiles
(Elsevier, 2021)
The present study has analysed the effect of cross-section geometry and the printing pattern of continuous carbon reinforced polyamide on the axial and radial crushing behaviour. Each geometry and printing pattern generated ...
Quasi-static and dynamic crush behaviour of 3D printed thin-walled profiles reinforced with continuous carbon and glass fibres
(Elsevier, 2021)
The present paper investigates the suitability of cFF printed material and technologies for crashworthiness applications. To this end, the quasi-static and dynamic crush behaviour of 3D printed thin-walled hollow profiles ...
