This paper proposes an all-pass filter-based true time delay (TTD) element covering a 3–5-GHz ultra-wideband (UWB) frequency. The proposed TTD element designed in a standard 0.18-µm CMOS technology achieves a tunable delay ...

In a previous study using mobile-health technology (mHealth), we reported a robust association between chronic fatigue symptoms and heart rate variability (HRV) in female patients with myalgic encephalomyelitis/chronic ...

L’ús de dispositius electrònics és una tendència a l’alça entre les noves generacions. Molt se’n sap de les contraindicacions o afectacions que pot arribar a provocar a nivell de salut. Però hi ha algun aspecte que en pugui ...

L’objectiu del present projecte és la posada en pràctica dels coneixements adquirits durant el grau, que s’hauran de materialitzar en el present treball. L’usuari d’una bicicleta i l’entorn que l’envolta, generen unes ...

En aquest projecte s’ha dissenyat i construït diversos acobladors híbrids i de Lange per aplicacions docents. S’han realitzat amb tecnologia microstrip a una freqüència de treball de 900 MHz. L’híbrid s’ha dissenyat ...

Steel fibers are ferromagnetic and they have the property of altering the magnetic field around them. This paper discusses a method and gives a practical example to measure, non-destructively, the amount and orientation ...

This paper presents an FIR operator with a very low computational cost for calculating the first derivative of discrete band-limited signals. The basic idea is to use cubic spline polynomials for interpolating among the ...

The aim of this work is to carry out a sustainability study in five campuses of the Universitat Politècnica de Catalunya BarcelonaTech (UPC) around Catalunya, i.e. Campus North and South Campuses in Barcelona city, Campus ...

With the trend of textile antennas development, ultra high frequency (UHF, 865–868 MHz) radio frequency identification (RFID) devices using textile materials are expected to be developed in many areas for replacing or ...
