A Modified Barrier and Barrier Method and the Optimal Power Flow Problem
(2017-01-01)
This work proposes an approach that uses a union of methods based on logarithmic barrier function and modified logarithmic barrier function for the resolution of the reactive optimal power flow problem. In this proposed ...
Relativistic effects in the energy loss of a fast charged particle moving parallel to a two-dimensional electron gas
(Elsevier Science, 2018-05-01)
We present a fully relativistic formulation for the energy loss rate of a charged particle moving parallel to a sheet containing two-dimensional electron gas, allowing that its in-plane polarization may be described by ...
Stopping power of cluster ions in a free-electron gas from partial-wave analysis
(American Physical Society, 2018-12)
A nonlinear model for the stopping power of cluster ions based on partial-wave analysis is developed through the generalization of the induced density approach (IDA) model for the interaction of homo- and heteronuclear ...
Stopping power and depth dose profile of H+ and He+ ion beams in hydroxyapatite thin films.
(Gdańsk University of TechnologySopot, 2013-05-20)
Hadron therapy is a promising technique to treat deep-seated tumors. For an accurate treatment planning, the energy deposition in the soft and hard human tissue must be well known. Water has been usually employed as a ...
Latin America Goes Electric: The Growing Social Challenges of Hydroelectric Development
(IEEE, 2013)
Hydroelectricity was, for many years, one of the main ways to meet the new electricity needs of Latin American countries. This is evidenced by the presence of some of the larger plants worldwide and the high hydroelectric ...
Nano-hillock formation in diamond-like carbon induced by swift heavy projectiles in the electronic stopping regime: Experiments and atomistic simulations
(American Institute Of Physics, 2012-09)
The formation of surface hillocks in diamond-like carbon is studied experimentally and by means of large-scale molecular dynamics simulations with 5 × 106 atoms combined with a thermal spike model. The irradiation experiments with ...

Segmentação automática de registros de oscilografia fasorial com ênfase em sistemas de geração
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2014-11-25)
With the ever increasing need to obtain the reliability of electric power generation systems, the study of disturbances that occur in these systems has become a key point in preventing the supply stops. With the development ...
Análise da vibração das moto-bombas de refrigeração dos geradores elétricos de Itaipu
(Universidade Tecnológica Federal do ParanáMedianeiraBrasilTecnologia em Manutenção IndustrialUTFPR, 2015-11-27)
This study was conducted at the Itaipu Hydroelectric Plant, in the set of moto-pumps which is part of pure water system that is intended to cooling some parts of the generating unit, specifically the stator bars of the ...
