CMS physics technical design report: Addendum on high density QCD with heavy ions
d'Enterria, D.; Ballintijn, M.; Bedjidian, M.; Hofman, D.; Kodolova, O.; Loizides, C.; Lokthin, I. P.; Lourenço, C.; Mironov, C.; Petrushanko, S. V.Made available in DSpace on 2022-04-28T20:22:10Z (GMT). No. of bitstreams: 0 Previous issue date: 2007-11-01; This report presents the capabilities of the CMS experiment to explore the rich heavy-ion physics programme offered by the CERN Large Hadron Collider (LHC). The collisions of lead nuclei at energies , will probe quark and gluon matter at unprecedented values of energy density. The prime goal of this res...
Autonomous temporal pseudo-labeling for fish detection
Veiga, Ricardo; Exposito Ochoa, Iñigo; Belackova, Adela; Bentes, Luis; Parente Silva, João; Semiao, J.; Rodrigues, JoãoThe first major step in training an object detection model to different classes from the available datasets is the gathering of meaningful and properly annotated data. This recurring task will determine the length of any project, and, more importantly, the quality of the resulting models. This obstacle is amplified when the data available for the new classes are scarce or incompatible, as in the case of fish de...
Multiple-output switched-capacitor DC-DC combination converters for IoT applica...
Semiao, J.; Duran, E.; Litran, S. P.; Ferrera, M. B.This paper presents and describes switched-capacitor DC-DC combination converters with a single input and multiple outputs, with step-down and step-up voltage ratios. The combination converters provide two or three different DC outputs (depending on the combination), with different conversion ratios. The main advantage of the proposed converters is the low number of components used in the combination (two-outpu...
Analysis of converters with bipolar output for DC microgrid
Litran, S. P.; Duran, E.; Barroso, R. S.; Semiao, J.; Ferrera, M. B.Bipolar DC networks have been shown as a suitable solution for low voltage (LV) energy distribution. This paper presents the advantages and disadvantages that they have with respect to other topologies, from the point of view of their implementation, efficiency in the use of energy and its ability to connect large loads. On the other hand, for this type of networks the use of DC-DC converters is required to con...
A Zeta-CSC converter combination for single-input and bipolar output
Litran, S. P.; Duran, E.; Ferrera, M. B.; Semiao, J.; Barroso, R. S.This paper presents a DC-DC converter of one input and one bipolar output. The converter has been obtained from the combination of two basic converters of one input and one output. Thus, the proposed configuration is the result of the combination of a CSC (Canonical Switching Cell) converter and a Zeta converter. A common feature of these converters is they have the same conversion relation. The input stage for...
A distributed load scheduling mechanism for micro grids
Monteiro, J. M.; Eduardo, J.; Cardoso, Pedro J. S.; Semiao, J.Several protocols have recently been defined for smart grids that enable the communication between electric devices and energy management systems. While these protocols and architectures can already be applied in different fields of micro grids, it is still not clear how the distributed resources and constraints of such electrical grids can be managed in an optimum way. In order to achieve a reduction in electr...
