Design of Permanent-Magnet Linear Generators with Constant-Torque-Angle Control for Wave Power
Energies, 2019 This paper presents a simulation method for direct-drive permanent-magnet linear generators designed for wave power. Analytical derivations of power and maximum damping force are performed based on Faraday’s law of induction and circuit equations ...

Control of Cascaded Multilevel Converter for Wave Energy Applications
Energies, 2022 This paper proposes a control scheme for a wave energy conversion system based on a linear generator and a cascaded multilevel converter. The mechanical conversion system is composed of a buoy connected directly to a linear generator. The windings of the

Backward stochastic differential equations with unbounded generators [PDF]
, 2018 In this paper we consider two classes of backward stochastic differential equations. Firstly, under a Lipschitz-type condition on the generator of the equation, which can also be unbounded, we give sufficient conditions for the existence of a unique ...

Journal of the Royal Statistical Society. Series A (General), 1972 The technique of iterative weighted linear regression can be used to obtain maximum likelihood estimates of the parameters with observations distributed according to some exponential family and systematic effects that can be made linear by a suitable transformation.

Optimal Constant DC Link Voltage Operation of aWave Energy Converter
Energies, 2013 This article proposes a simple and reliable damping strategy for wave powerfarm operation of small-scale point-absorber converters. The strategy is based on passiverectification onto a constant DC-link, making it very suitable for grid integration of the

General linear-optical quantum state generation scheme: Applications to maximally path-entangled states [PDF]
, 2007 We introduce schemes for linear-optical quantum state generation. A quantum state generator is a device that prepares a desired quantum state using product inputs from photon sources, linear-optical networks, and postselection using photon counters.

The generalized linear periods
Journal of Number Theory, 2022 Let $F$ be a non-archimedean local field of characteristic zero. We study the linear period problem for the pair $(G,H_{p,p+1})=(GL_{2p+1}(F), GL_{p}(F)\times GL_{p+1}(F))$ and we prove that any bi-$(H_{p,p+1}, )$-invariant generalized function on $G$ is invariant under the matrix transpose when is a good character. We also show that any $P\cap H_{p,
