A geometric interpretation for transmission real losses minimization through the optimal power flow and its influence on voltage collapse
(Elsevier B.V., 2002-06-28)
This work presents an approach for geometric solution of an optimal power flow (OPF) problem for a two bus system (a slack and a PV busses). Additionally, the geometric relationship between the losses minimization and the ...
Friction losses in valves and fittings for viscoplastic fluids
(Canadian Soc Chemical Engineering, 2005-04-01)
Data on pressure drop were obtained in stainless steel, sanitary fittings and valves during laminar and turbulent flow of aqueous suspensions of sucrose and bentonite. The rheological properties of these suspensions were ...

Electronic ion energy loss calculations on the basis of the binary encounter approximation
(Elsevier, 1999)
Electronic ion energy loss calculations on the basis of the binary encounter approximation are presented for protons in oxygen, nitrogen and silicon. Calculations using both an analytical approach as well as a Monte Carlo ...
Correction of power transformer no-load losses, measured under nonsinusoidal voltage waveforms
(IEEE, 1989)
A method to calculate the iron losses in power transformers with highly distorted supply voltages is introduced. The appearance of small loops inside the main hysteresis loop is analysed and a method is proposed that takes ...
Identification of areas with soil loss above the tolerable using NDVI for calculating the C factor of USLEIdentificaçào de áreas com perda de solo acima do tolerável usando NDVI para o cálculo do fator C da USLE
(2017-12-01)
One of the main problems related to the conservation of the watershed soils is the hydric erosion of the soil, leading to particles transportation to water bodies as consequence, especially in those regions with agricultural ...
