Integrating multiple stubs in stepped-impedance filter aiming for high selectivity
A design technique to include multiple and fully-controlled transmission zeros (TZs) in the frequency response of rectangular waveguide commensurate-line stepped-impedance filters is presented in this letter. These bandpass ... -
Network simulation in a TCP-enabled industrial internet of things environment - reproducibility issues for performance evaluation
Network simulation is a tool used to analyse and predict the performance of Industrial Internet of Things deployments while dealing with the complexity of real testbeds. Large network deployments with complex protocols ... -
High performance fiber laser resonator for dual band (C and L) sensing
(IEEE, 2022) Artículo / ArtikuluaThis work presents an experimental analysis and comparison of the performance of quasi-randomly distributed reflectors inscribed into a single-mode fiber as a sensing mirror both in C- and L-band. Single-wavelength emission ... -
On some classes of nullnorms and h-pseudo homogeneity
(Elsevier, 2022) Artículo / ArtikuluaNullnorms are aggregation functions which generalize t-norms and t-conorms. For each nullnorm there exists an annihilator element such that, below it, the function behaves like a t-conorm, and, above it, like a t-norm. ... -
A comprehensive survey on 'circular polarized antennas' for existing and emerging wireless communication technologies
Circular polarized (CP) antennas are well suited for long-distance transmission attainment. In order to be adaptable for beyond 5G communication, a detailed and systematic investigation of their important conventional ... -

Simulation model for wire harness design in the car production line optimization using the SimPy library
The automotive industry is one of the most important economic sectors in the world. At the beginning, vehicles only had mechanical components, so the use of an automotive wire harness was not indispensable. Cars today are ... -
A multi-object grasp technique for placement of objects in virtual reality
Some daily tasks involve grasping multiple objects in one hand and releasing them in a determined order, for example laying out a surgical table or distributing items on shelves. For training these tasks in Virtual Reality ... -
Fault detection of planetary gears based on signal space constellations
A new method to process the vibration signal acquired by an accelerometer placed in a planetary gearbox housing is proposed, which is useful to detect potential faults. The method is based on the phenomenological model and ... -
Gamification and a low-cost laboratory equipment aimed to boost vapor compresion refrigeration learning
The nowadays European educational framework boosts applying the learned theoretical concepts to real situations. Hence, practice sessions are key resources to present students direct applications of the theoretical concepts ... -
On the measurement of stability parameter over complex mountainous terrain
Atmospheric stability has a significant effect on wind shear and turbulence intensity, and these variables, in turn, have a direct impact on wind power production and loads on wind turbines. It is therefore important to ... -
