Critical success factors of University-Industry R&D collaborations
University-industry R&D collaborations (UICs) play a vital role in stimulating open innovation that leads to new products,
processes, and services that creates value for customers and broader societal impact. UICs, however, commonly fail to meet these
stakeholders’ benefits. This study identifies thirty-four critical success factors (CSFs) for improving UIC success. The study
includes a systematic literature review and a longitudinal UIC case study between Bosch Car Multimedia in Portugal and University
of Minho, a multi-million Euro R&D collaboration from 2013 to 2021. The importance of the CSFs is discussed in the context of
the UIC lifecycle. A survey among researchers and industry practitioners involved in R&D collaborative projects was completed
to confirm the analysis of the empirical results. This paper provides UIC managers with CSFs, which, when addressed competently,
can provide a basis for successful UIC projects and sustainable university-industry collaborationsThe authors are grateful to the Foundation for Science and Technology (FCT, Portugal) for financial support

Electrochemical behavior of Ti/Al2O3 interfaces produced by diffusion bonding
In the field of biomedical applications a special interest exists regarding the study of the physicochemical and mechanical behaviour of materials, with special focus on the electrochemical degradation of metal/ceramic interfaces. In fact, etal/ceramic interfaces may be present in several
biomedical devices, ranging from external or implantable sensors, to dental implants. Diffusion
bonding represents an important technique since, in opposition to other production technologies,
such as active metal brazing, avoid the possible liberation of certain chemical components
harmful to health. The aim of this work is to study the electrochemical degradation of the interface
formed between commercially pure Ti and Al2O3 produced by diffusion bonding, in contact with
a physiological solution. The present approach included the evaluation of the contribution of individual
and pairs of interfacial layers on the global degradation processes. For this propose d.c.
electrochemical techniques were used to monitor the open-circuit potential, and to perform
potentiodynamic polarization and galvanic corrosion evaluation. Also, electrochemical impedance
spectroscopy was used as a complementary technique of the corrosion behaviour of the
interface. Chemical composition and morphology of samples and corrosion products were evaluated
by SEM and EDS analysis. According to experimental results, two principal reaction layers
were formed in the interface: TiAl and Ti3Al. The TiAl layer appears to be the responsible for the
strong increase in corrosion rate of the interface.Fundação para a Ciência e Tecnologia -POCTI/CTM/33384/2000; SFRH/BPD/

Gravitational Collapse of Phantom Fluid in (2+1)-Dimensions
This investigation is devoted to the solutions of Einstein's field equations
for a circularly symmetric anisotropic fluid, with kinematic self-similarity of
the first kind, in -dimensional spacetimes. In the case where the radial
pressure vanishes, we show that there exists a solution of the equations that
represents the gravitational collapse of an anisotropic fluid, and this
collapse will eventually form a black hole, even when it is constituted by the
phantom energy.Comment: 10 page
Linear and non-linear perturbations in dark energy models
I review the linear and second-order perturbation theory in dark energy
models with explicit interaction to matter in view of applications to N-body
simulations and non-linear phenomena. Several new or generalized results are
obtained: the general equations for the linear perturbation growth; an
analytical expression for the bias induced by a species-dependent interaction;
the Yukawa correction to the gravitational potential due to dark energy
interaction; the second-order perturbation equations in coupled dark energy and
their Newtonian limit. I also show that a density-dependent effective dark
energy mass arises if the dark energy coupling is varying.Comment: 12 pages, submitted to Phys. Rev; v2: added a ref. and corrected a

Detection of inconsistencies in geospatial data with geostatistics
Almost every researcher has come through observations that “drift” from the rest of the sample, suggesting some inconsistency. The aim of this paper is to propose a new inconsistent data detection method for continuous geospatial data based in Geostatistics, independently from the generative cause (measuring and execution errors and inherent variability data). The choice of Geostatistics is based in its ideal characteristics, as avoiding systematic errors, for example. The importance of a new inconsistent detection method proposal is in the fact that some existing methods used in geospatial data consider theoretical assumptions hardly attended. Equally, the choice of the data set is related to the importance of the LiDAR technology (Light Detection and Ranging) in the production of Digital Elevation Models (DEM). Thus, with the new methodology it was possible to detect and map discrepant data. Comparing it to a much utilized detections method, BoxPlot, the importance and functionality of the new method was verified, since the BoxPlot did not detect any data classified as discrepant. The proposed method pointed that, in average, 1,2% of the data of possible regionalized inferior outliers and, in average, 1,4% of possible regionalized superior outliers, in relation to the set of data used in the study
