Superregeneration revisited: from principles to current applications
(2020-02-01)
Article
Open AccessWireless communications play a central role in our modern connected lives; at the same time, they constitute a very broad and deep area of research. The elements that make wireless communications possible are a transmitter, ... -
An interdisciplinary approach to motivate students to learn digital systems and computing engineering
(Tempus Publications, 2019-03-01)
Article
Restricted access - publisher's policyWe report a new learning approach in collaborative learning-by doing, real-world team-based project in two ICT courses: DigitalSystems and Computing Engineering, conducted at Universitat Polite`cnica de Catalunya. Data ... -
Optimal batch scheduling of a multiproduct dairy process using a combined optimization/constraint programming approach
(Pergamon Press, 2019-03-08)
Article
Restricted access - publisher's policyThis paper presents the optimal batch scheduling of a multi-product dairy process using an approach that combines optimization and constraint programming techniques. A suitable model describing the subprocesses and production ... -
A discrete-time technique for the steady-state analysis of nonlinear class-E amplifiers
(Institute of Electrical and Electronics Engineers (IEEE), 2007-06-11)
Article
Open AccessSwitched circuits are widely used, particularly for power electronic applications in which efficiency is important. Of these applications, the class-E amplifier has been given particular attention, since it is theoretically ... -
Joint symbol and chip synchronization for a burst-mode-communication superregenerative MSK receiver
(2017-01-05)
Article
Open AccessIn this paper we describe a superregenerative (SR) MSK receiver able to operate in a burst-mode framework where synchronization is required for each packet. The receiver is based on an SR oscillator which provides samples ... -
A discrete-time approach to the steady-state and stability analysis of distributed nonlinear autonomous circuits
(2000-02)
Article
Open AccessWe present a direct method for the steady-state and stability analysis of autonomous circuits with transmission lines and generic non- linear elements. With the discretization of the equations that describe the circuit ... -
Stability analysis of periodic solutions in non-linear autonomous circuits: a discrete time approach
(1996-07)
Article
Restricted access - publisher's policySteady-state methods have been devised to compute periodic wave-forms without having to integrate the autonomous circuit equations until the transients die out. Stability analysis of the computed solutions is the next ... -
The Mendeleev-Meyer force project
(2016-10-28)
Article
Open AccessHere we present the Mendeleev–Meyer Force Project which aims at tabulating all materials and substances in a fashion similar to the periodic table. The goal is to group and tabulate substances using nanoscale force footprints ... -
Circuitos de capacidades conmutadas. Análisis frecuencial por ordenador
(1985-10)
Article
Restricted access - publisher's policyEl interés fundamental de los circuitos de condensadores conmutados radica en su aplicación a la realización de filtros monolíticos y de otros bloques funcionales para su tratamiento analógico de la señal. Resulta del ... -
Formalism for a multiresolution time series database model
(2016-03)
Article
Open AccessWe formalise a specialised database management system model for time series using a multiresolution approach. These special purpose database systems store time series lossy compressed in a space-bounded storage. Time series ... -
Single cycle and transient force measurements in dynamic atomic force microscopy
(2013-11-21)
Article
Open AccessThe monitoring of the deflection of a micro-cantilever, as the end of a sharp probe mounted at its end, i.e. the tip, interacts with a surface, forms the foundation of atomic force microscopy AFM. In a nutshell, developments ... -
Establishing nanoscale heterogeneity with nanoscale force measurements
(2015-08-13)
Article
Open AccessEstablishing the presence or absence of nanoscale compositional heterogeneity with nanoscale resolution is becoming instrumental for the development of many fields of science. Force versus distance measurements and parameters ...
