Light-induced space-charge fields in lithium niobate crystals are used to trap and manipulate dielectric particles on the surface of such crystals. Without any external voltage source, strong field gradients are present in the proximity of the crystal surf ...
The adjunction of constrictions along the meander of a superconducting Fault Current Limiter (FCL) greatly improves its behavior thanks to a better distribution of the dissipative zones at the occurrence of a short circuit. This design works perfectly for ...
The theme of this dissertation is the study of housing in Lisbon's Baixa Pombalina blocks of flats. It aims to understand the spatial organisation of houses and to study the ways of qualified intervention, thus seeking possible guidelines for future projec ...
In this paper a floating body partially depleted SOI MOSFET used to measure light intensity using the transient charge pumping [1] is modeled through an equivalent electrical circuit. Essentially, photogenerated charges of the MOSFET are converted into a c ...
The paper describes a new motion detection circuit that extracts motion information based on a time-to-travel algorithm. The front-end photoreceptor adapts over 7 decades of background intensity and motion information can be extracted down to a contrast va ...
The problem of energy optimization in multi-core systems (such as single-chip multiprocessors) where the individual energy demands of various processing elements are governed by instantaneous workload requirements is well defined in literature. The signifi ...
The contact resistance distribution among the current-carrying elements of three ITER conductor terminations is measured in the JORDI (JOint Resistance DIstribution) test facility at CRPP. One sample is based on Nb3Sn strands, the other two are NbTi cable- ...
A novel 8-bit current mode interleaved successive approximation (SAR) analog-digital converter (ADC) has been proposed. The proposed converter architecture is very flexible. Using two control DC voltages and one reference current, the converter can be tune ...

We present local and non-local electron transport measurements on individual multi-wall nanotubes for bias voltages between 0 and about 4 V. Local current–voltage characteristics are quite linear. In contrast, non-local measurements are highly nonlinear; t ...
