Power analysis applying the instantaneous complex power analytical expressions on a RL symmetrical three-phase system
(1997-12-01)
This paper enhances some concepts of the Instantaneous Complex Power Theory by analyzing the analytical expressions for voltages, currents and powers developed on a symmetrical RL three-phase system, during the transient ...

The expressive power of memory logics
(Cambridge University Press, 2011-06)
We investigate the expressive power of memory logics. These are modal logics extended with the possibility to store (or remove) the current node of evaluation in (or from) a memory, and to perform membership tests on the ...
A closed-form expression for the received power through the usage of the Dirac-Delta functions with nonlinear argument
(Institute of Electrical and Electronics Engineers Inc., 2015-06)
We present a closed-form expression for the received power through parametrized Dirac-Delta functions inside the framework of input and output integrals. This expression is derived from the 'spike' property of the Dirac-Delta ...
Grid-tie three-phase inverter with active power injection and reactive power compensation
(2016-11-05)
This paper proposes a methodology for the active and reactive power flow control, applied to a grid-tie three-phase power inverter, considering local and/or regionalized power flow control necessity in the forthcoming ...

Expressive Path Queries on Graphs with Data
(Springer, 2015)
Graph data models have recently become popular owing to
their applications, e.g., in social networks, semantic web. Typical navigational
query languages over graph databases — such as Conjunctive
Regular Path Queries ...
The power of modal separation logics
(Oxford University Press, 2019-12)
We introduce a modal separation logic MSL whose models are memory states from separation logic and the logical connectives include modal operators as well as separating conjunction and implication from separation logic. ...
