Automatic white-box testing of first-order logic ontologies
(Oxford Academic, 2019-02-26)
Formal ontologies are axiomatizations in a logic-based formalism. The development of formal ontologies is generating considerable research on the use of automated reasoning techniques and tools that help in ontology ...
Accurate microthermometer based on off center polymer caps onto optical fiber tips
(Elsevier, 2018-05-26)
We report on microscopic polymer spherical caps bonded onto the cleaved end of a single-mode fiber (SMF) for
fast, accurate, and sensitive temperature sensing. The microcaps were fabricated by dispensing sub nano-liter
amounts ...
Design and implementation of a droop control in d-q frame for islanded microgrids
(The Institution of Engineering and Technology, 2013-09-01)
The droop control method is usually selected when several distributed generators (DGs) are connected in parallel forming an islanded microgrid. This is because of the advantages it offers such as flexibility, absence of ...
Effect of the sampling rate on the assessment of flicker severity due to phase jumps
(IEEE, 2011)
This paper presents an analysis of the effect of the sampling rate on the calculation by a digital flickermeter of the flicker severity caused by phase jumps. The new edition of the IEC 61000-4-15 standard includes an ...
Effect of different organosolv treatments on the structure and properties of olive tree pruning lignin
(Elsevier, 2014-05-25)
Different organosolv processes (acetosolv, formosolv and acetosolv/formosolv) were applied to extract lignin from olive tree pruning. Obtained lignins were characterized by several methods to determine their composition, ...

(Emerald Publishing, 2019-02-28)
Purpose: The purpose of this paper is to examine the role of digital competences in relation to the general competences demanded by the job market in the case of Business graduates’ future.
Design/methodology/approach: A ...
Efficacy of management policies on protection and recovery of natural ecosystems in the Urdaibai Biosphere Reserve
(Natural Areas Association, 2011-10-01)
Knowledge of landscape patterns and dynamics is essential for land use planners and natural resources managers. They need to know how landscapes have changed in order to determine the consequences and efficacy of the ...
Fully Functionalizable β,β'-BODIPY Dimer: Synthesis, Structure, and Photophysical Signatures
(ACS, 2018-08-16)
The versatility in the synthesis of BODIPY derivatives in terms of
functionalization is further demonstrated. Particularly, in this work β−β’-BODIPY dimers
with varied functional groups in the meso-positions were synthetized ...
Functional surfaces through the creation of adhesion and charged patterns on azopolymer surface relief gratings
(2019-03-29)
We show that an azopolymer can be used to create a supramolecular architecture in a parallel process with patterned surface properties. By illuminating with an interference pattern, we created adhesion and charge patterns ...
Effects of a putative antidepressant with a rapid onset of action in defeated mice with different coping strategies
(Elsevier, 2012-04-22)
There is evidence suggesting that stressful social events may result in depressive-like disorders, but the development of these disorders depend on the way in which people cope with stress. Although antidepressants are ...
