Computational Modelling of Three Different Sub-Boundary Layer Vortex Generators on a Flat Plate
(MDPI, 2018-11-10)
Flow separation is the source of several problems in a wind turbine including load fluctuations, lift losses, and vibrations. Vortex generators (VGs) are passive flow control devices used to delay flow separation, but their ...
A More Flexible Model or Simply More Effort? On the Use of Correlated Random Parameters in Applied Choice Studies
(Elsevier, 2018-08-28)
The random parameter logit model has become the dominating model for analyzing stated choice data in environmental valuation. The unrestricted version of the model with correlated random parameters, however, is rarely ...
Demand for culture in Spain and the 2012 VAT rise
(Springer, 2018)
[EN] This paper analyzes the effects that the 2012 VAT rise in Spain had on household’ demand for cultural goods and services. Household’ demands are modeled as a two-stage QUAIDS. After estimating price and expenditure ...
Marine Aerosol Weathering of Mediterranean Calcarenite Stone: Durability of Ethyl Silicate, Nano Ca(OH)2, Nano SiO2, and Nanostructured Consolidating Products
(Taylor & Francis, 2018-07-13)
Calcarenite stone samples from a historic building (Bizerte, Tunisia) were collected and treated
under different environmental conditions with several consolidating products: alkoxysilane
(ethyl silicate), a surfactant-templated ...
Profitable strategic delegation with conjectural variations
(Wiley, 2018)
[EN] Firms delegate strategic decisions to managers because they find it profitable to do so. In the product market, when agents make conjectures about the reaction of their rivals to marginal changes in their own strategies, ...
Lipidomimetic Compounds Act as HIV-1 Entry Inhibitors by Altering Viral Membrane Structure
(Frontiers Media, 2018-09-04)
The envelope of Human Immunodeficiency Virus type 1 (HIV-1) consists of a liquid-ordered membrane enriched in raft lipids and containing the viral glycoproteins. Previous studies demonstrated that changes in viral membrane ...
Atomistic Simulations of Geopolymer Models: The Impact of Disorder on Structure and Mechanics
(ACS, 2018-06-13)
Geopolymers are hydrated aluminosilicates with excellent binding properties. Geopolymers appeal to the construction sector as a more sustainable alternative to traditional cements, but their exploitation is limited by a ...
Variable speed wind turbine control scheme using a robust wind torque estimation
(Elsevier, 2018-10-04)
This work proposes a robust controller for a variable speed wind turbine system with a doubly feed induction generator. The controller aims at tracking the optimal speed of the wind turbine so that extracts the maximum ...
International Political Economy of Labour and collective bargaining in the automotive industry
(Sage, 2018-03-23)
This article shows how International Political Economy of Labour (IPEL) approaches can be fruitful in the study of working class and institutional transformation in contemporary capitalism. It draws from an analysis of ...
To sign or not to sign? Union strategies towards provincial metal sector agreements in the Catalan and Basque automotive industries
(Sage, 2018-07-13)
I compare collective bargaining in the Basque and Catalan automotive industries to show that since the early 2000s, two contrasting bargaining frameworks have emerged. The two largest Spanish unions have followed ‘top-down’ ...
