international
level
and
provide

The
Environment
Analysis
determine
the

that
can
affect
us
through
an

and
a
discussion
of
the
direct
competition.
Ending
the
chapter
with
observing
the
market
and
sector
in
which
the
company
develops.
In
the
next
chapter
Analysis
of
Operations
and
processes
we
have
considered
losprincipales

there
in
the
company
as
well
as
the
type

operations
that
define
its

and
logistics,
both
internal
and
external,
that
the
company
develops.
In
Chapter
5,
Analysis
of
Organization
and
Human
Resources,
we
developed
the
overall
purpose
of
the
business,
through
the
mission,
vision
and
objectives
as
well
as
the
location
of
the
units
that
make
up
the
structure,
relationships,
the
characteristics
of
dependence
and
basic

of
each

are
related
to
the

in
order
to
study
the
terms
of
trade
and

customer
better
understand
how
to
reach
the
target
audience
of
our

Consecutively
perform
an
Economic
and
Financial
Analysis,
through
the
annual
accounts
for
the
last
3
years
and
the
development
of
certain
ratios,
to
thereby
study
how
to
improve
the
situation
and
correct
any
errors.
Once
all
the
data
collected
from
the
previous
chapters
we
conducted
a
CAME
/
SWOT
analysis,
to
establish
the
key
areas
for
improvement
and
actions
to
perform.
After
all
these
analyzes
we
perform
the
Identification
and
Assessment
Improvement
Proposal,
where
after
establishing
a
number
of
improvements
have
been
chosen
in
the
best
position
to
perform
with
resources
and
set
time. Finally
we
conclude
by
specifying
possible
repercussions
that
produce
the
measures
taken
in
the
company
and
if
they
meet
the
expectations
of
the
company.
The
main
limitations
encountered
when
performing
the
work
have
been
mainly:
-‐
The
realization
of
the
forecast
medium
and
long
term
by
the
constant
changes
in
the
general
economic
climate.
-‐
The
difficulty
for
updated
sectoral
data
from
different
sources,
both
nationally
and
internationally.
-‐
Difficulty
sufficiently
structured
to
extract
information
about
the

Studying how our future teachers learn. Analysis of their learning styles in virtual communication environments
Get PDFEl uso de las Tecnologías de la Información y la Comunicación como recurso educativo es cada vez
más común. Además, el desarrollo de la Sociedad del Conocimiento, la convergencia europea y la crisis
social y económica están obligando a reformular los procesos de enseñanza y aprendizaje en las aulas.
En consecuencia, consideramos de gran importancia plantearnos el uso de estos nuevos recursos didácticos
en relación con el estilo de aprendizaje de aquellos que participan en los procesos formativos
dentro de la Universidad. El trabajo que presentamos es un estudio sobre los estilos de aprendizaje
virtuales de un grupo de estudiantes universitarios, de segundo curso de Magisterio observando la
existencia o no de diferencias en relación a las distintas especialidades que cursanThe use of Information and Communication Technology as an educational resource is more and more
common. Also, the development of the Knowledge Society, the European convergence and the social
and economic crisis are forcing us to reformulate the Teaching and Learning processes in the classroom.
Consequently, we consider that it is of utmost importance to promote the use of these new didactic resources
related with the learning style of those who take part in the training processes within the University.
The work that we present is a study of virtual learning styles of a group of university students, second
year teacher trainees, observing whether or not differences exist regarding the different areas of stud
Self-Adaptative Troubleshooting for to Guide Resolution of Malfunctions in Aircraft Manufacturing
Get PDFThe increasing complexity of systems and the heterogeneous origin of the possible malfunctions
bring about the necessity of rede ning the troubleshooting processes. Troubleshooting comprises the
set of steps for the systematic analysis of the symptoms after the detection of a malfunction. The complexity
of certain systems, such as aircraft, means the origin of that malfunction can be any of several reasons, where
diagnosis techniques support engineers in determining the reason for the unexpected behaviour. However,
derived from the high number of components involved in an aircraft, the list of possible fault origins can
be extremely long, and the analysis of every element on the list, until the element responsible is found,
can be very time-consuming and error-prone. As an alternative, certain input/output signals can be read to
prevent the substitution of a correctly functioning component, by validating its behaviour in an indirect
way. In order to optimise the actions to perform, we have identi ed the relevant parts of the model to
propose a troubleshooting process to ascertain the signals to read and the components to substitute, while
striving to minimise the action cost in accordance with a combination of structural analysis, the probability of
malfunction associated to the components, and the cost associated to each extra signal read and component
substituted. The proposal has been validated in a system taken from a real scenario obtained in collaboration
with the Airbus Defence and Space company. A statistical analysis of the degree of improvement of the
troubleshooting process has also been included.Ministerio de Ciencia e Innovación RTI2018-094283-B-C3

New iridium complex as additive to the spiro-OMeTAD in perovskite solar cells with enhanced stability
Get PDFA new iridium complex, IrCp*Cl(PyPyz)[TFSI], has been synthesized and used as additive for the hole transporter material, spiro-OMeTAD, in perovskite solar cells. The cells prepared with this Ir additive present higher efficiency than reference cells, and similar to cells prepared with Co additive. We have determined that the presence of metal complexes as additives decreases the recombination rate, as it has been observed by impedance spectroscopy. Very interestingly, while the efficiency after 3 months decreases by 22% and 70% for reference cell and cell with Co additive, respectively, the efficiency of devices containing the Ir additive is only decreased by a 4%
Sensory System for Implementing a Human—Computer Interface Based on Electrooculography
Get PDFThis paper describes a sensory system for implementing a human–computer interface based on electrooculography. An acquisition system captures electrooculograms and transmits them via the ZigBee protocol. The data acquired are analysed in real time using a microcontroller-based platform running the Linux operating system. The continuous wavelet transform and neural network are used to process and analyse the signals to obtain highly reliable results in real time. To enhance system usability, the graphical interface is projected onto special eyewear, which is also used to position the signal-capturing electrodes
Up-Converting Lanthanide-Doped YAG Nanospheres
Get PDFThe development of lanthanide-doped Y3Al5O12 (Ln:YAG) garnet nanostructures is
a hot topic in the field of inorganic nanophosphors due to the current interest
in developing small nanoparticles for solid-state lighting (SSL), displays, lasers and
scintillation applications. In this study, we report the preparation of homogeneous
Ln:YAG (Ln: Ho/Yb ions) nanospheres through a combined two-steps coprecipitationsolvothermal synthesis at low temperature. The crystal growth takes place in ethylene
glycol, which is an inexpensive, non-toxic and easily available solvent. Monodisperse
and crystalline spherical YAG particles of 80 nm in diameter were obtained. Furthermore,
the protocol can be extended to other compositions (Tb/Yb, Tm/Yb. . .) to explore
different luminescent properties, without affecting the morphology of the material,
indicating the robustness and practical utility of the reported methodology. Thermal
treatment of the nanogarnets at 1200◦C is necessary for making materials optically
active upon both UV and NIR excitation. The spherical morphology of annealed samples
is preserved, what helps their further dispersion in solvents, barbotines, inks or printing
vehicles. The lanthanide-doped nanogarnets exhibited the characteristic blue, green
and red emissions from lanthanide upconversion photoluminescence (UCPL) upon NIR
excitation. The UCPL mechanism was studied and CIE chromate coordinates were
obtained. These nanogarnets were further evaluated as functional ceramic phosphors
by incorporating them into commercial glazes. The materials exhibited an exceptional
chemical stability in a harsh medium such as a fused glaze. Consequently, the visible
emissions of the nanoparticles were transferred to the whole glass matrix, thus providing
a functional glaze that emits intense blue and green light upon NIR excitation. These
luminescent nanogarnets have promising applications in smart enamels, but can
also be useful for lighting displays (white LEDs. . .), smart paintings or plastics, and
anti-counterfeiting systems
