This paper proposes a new topology of quasiZ-source inverter(qZSI) which is used as step-up isolated dc/dc converter for residential fuel cell (FC) power systems .The proposed topology used is cascaded quasi Z source inverter and implemented using induction motor. The cascaded qZSI is derived by the adding of one diode, one inductor and two capacitors to the traditional qZSI. The proposed two-s...

A novel algebraic topology approach to supersymmetry (SUSY) and symmetry breaking in quantum field and quantum gravity theories is presented with a view to developing a wide range of physical applications. These include: controlled nuclear fusion and other nuclear reaction studies in quantum chromodynamics, nonlinear physics at high energy densities, dynamic Jahn–Teller effects, superfluidity, ...

This paper presents a novel topology of single-phase multilevel inverter for low and high power applications. It consists of polarity (Level) generation circuit and H Bridge. The proposed topology can produce higher output voltage levels by connecting dc voltage sources   in series and parallel. The proposed topology utilizes minimum number of power electronic devices which helps in reduction o...

The passively clamped quasi-resonant dc-link (PCQRL) inverter basic topology and other quasi-resonant inverters have been shown to be only partially compatible with pulsewidth modulation (PWM), due to a minimum dwell time created by the clamping mode in the inverter operation. This paper addresses this kind of modulation nonlinearity, employing the space-vector approach as a modeling tool. Clos...

After fixing a marking (V,W ) of a quasi-Fuchsian punctured torus group G, the complex length λV and the complex twist τV,W parameters define a holomorphic embedding of the quasi-Fuchsian space QF of punctured tori into C2. It is called the complex Fenchel-Nielsen coordinates of QF . For c ∈ C, let Qγ,c be the affine subspace of C2 defined by the linear equation λV = c. Then we can consider the...

Thurston’s ending lamination conjecture proposes that a finitelygenerated Kleinian group is uniquely determined (up to isometry) by the topology of its quotient and a list of invariants that describe the asymptotic geometry of its ends. We present a proof of this conjecture for punctured-torus groups. These are free two-generator Kleinian groups with parabolic commutator, which should be though...

We prove that the quasi-periodic Schrödinger operator with a finitely differentiable potential has purely absolutely continuous spectrum for all phases if frequency is Diophantine and sufficiently small in corresponding $$C^k$$ topology. This extends work of Eliasson [19] Avila–Jitomirskaya [5] from analytic topology to one which much broader, revealing interesting phenomenon oscillation leads ...

The strong inclusion, a specific type of subrelation of the order of a lattice with pseudocomplements, has been used in the concrete case of the lattice of open sets in topology for an expedient definition of proximity, and allowed for a natural point-free extension of this concept. A modification of a strong inclusion for biframes then provided a point-free model also for the non-symmetric var...

Given a projective variety X and a smooth projective curve C one may consider the moduli space of maps C → X. This space admits certain compactification whose points are called quasi-maps. In the last decade it has been discovered that in the case when X is a (partial) flag variety of a semi-simple algebraic group G (or, more generally, of any symmetrizable Kac-Moody Lie algebra) these compacti...
