We consider a bounded domain nR⊂Ω whose regular boundary 21ΓΓ=Ω∂=Γ∪ consists of the union of two disjoint portions 1Γ and 2Γ with positive measures. The convergence of a family of continuous Neumann boundary mixed elliptic ...

This master’s dissertation proposes space vector modulation strategies for the Five-Levels Packed U-Cell converter with optimization on the commutation number and balance of the floating capacitors by use a cost function. ...

The noncommutative space-time model introduced by Doplicher, Fredenhagen and Roberts (DFR), is based on commutation relations of the form [qu, qv] = Lp Quv for the quantum coordinate operators qu, where Lp represents a ...

1/N2 corrections to deep inelastic scattering (DIS) of charged leptons from glueballs at strong coupling are investigated in the framework of the gauge/gravity duality. The structure functions F1 and F2 (and also FL) are ...

In the category    Δo Ens   ,   of the simplicial sets, there exists a "Unit interval" : the simplicial set   Δ[1],     with extremities   εi : Δ[0] → Δ[1] (i = 0, 1) ([1], [2] ). On the other hand, since in   Δo Ens, ...

This Ph. D. dissertation presents contributions to the investigation of soft-switching cells with integrated components, presenting three main approaches: (i) Soft-switching cells with filter coupled inductor; (ii) Integrated ...

This Thesis contributes to the modulation of the multi-level three-phase converter with flying capacitors, for which simulations were performed to validate three different modulation algorithms. The first one is a phase ...
