Study of Mortar Formulations for Underfloor Heating Systems Incorporating Steel...
Figueira, A.; Rebelo, F.; Paiva, H.; Figueiredo, A.; Almeida, R.; Vicente, R.; Ferreira, V.Considering the European targets for energy efficiency and decarbonization, without compromising thermal comfort, it’s necessary to define more efficient and sustainable air conditioning solutions, in terms of design, use of materials and even system efficiency. Improving the thermal properties of mortars used in underfloor heating systems is a promising strategy for increasing the thermal and energy efficiency...

Análisis del efecto de materiales de cambio de fase sobre la demanda de calefac...
Rebelo, F.; Corredera, A.; Andrés, M.; Vicente, R.; Morentin, F.; Ferreira, V.M.; Samaniego, J.; Figueiredo, A.; Bujedo, L.A.RESUMEN: Este trabajo evalúa el efecto que tiene la integración de materiales de cambio de fase (MCF) en la envolvente de los edificios, sobre la operación de un sistema de generación solar fotovoltaica acoplado con bomba de calor para cubrir las necesidades térmicas de dicho edificio. A partir de una instalación a escala real, se han realizado modelos en EnergyPlus de diferentes escenarios de estudio intermedi...
Interview anxiety narrative validation for a virtual reality-based study
Borges, T.; Ramos, S.; Vilar, E.; Noriega, P.; Rebelo, F.When conducting a Virtual Reality-based study one important feature that needs to be assured is valid is the narrative context. Our objective was to validate a job interview anxiety provoking narrative. One experiment with a between-subject design was conducted. Participants were instructed to read a job interview-context narrative and then self-report the level of anxiety experienced. Results indicated that th...
Nonlinear 3D foot FEA modeling from CT scan medical images
Antunes, P. J.; Dias, Gustavo R.; Coelho, A. T.; Rebelo, F.; Pereira, TiagoA 3D anatomically detailed non-linear finite element analysis human foot model is the final result of density segmentation 3D reconstruction techniques applied in Computed Tomography (CT) scan DICOM standard images in conjunction with 3D Computer Aided Design operations and finite element analysis (FEA) modelling. Density segmentation techniques were used to geometrically define the foot bone structure and the ...
O contributo do design ergonómico na interacção com dispositivos de controlo: u...
Ramos, S.; Gonçalves, I.; Simões, H.; Rebelo, F.Neste artigo é apresentado um estudo de caso desenvolvido por uma equipa multidisciplinar numa indústria de concepção de transformadores. A intervenção foca-se na interacção dos trabalhadores com os dispositivos envolvidos na realização da actividade, em particular, nas consequências que derivam do facto destes dispositivos não serem desenvolvidos numa perspectiva de design centrado no utilizador. É descrito o ...
Hyperelastic modelling of cork-polyurethane gel composites: non-linear FEA impl...
Antunes, P. J.; Dias, Gustavo R.; Coelho, A. T.; Rebelo, F.; Pereira, T.The CPGC – Cork-Polyurethane Gel Composite is a material that is mechanically characterized by non-linear elastic behaviour at large deformations. The non-linear behaviour can be modelled by hyperelastic constitutive models based on strain energy functions enabling a structured phenomenological framework for CPGC material modelling. The CPGC is a promising material for human comfort enhancement and dynamic damp...
