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...

Quantum error correcting codes are essential for successful implementation of quantum computers. We look into the theory of a particular class of quantum codes that look promising called quantum stabilizer codes. The aim of this project is to study and construct efficient quantum stabilizer codes from algebraic geometry codes.

The malic enzyme from Halobacterium cutirubrum requires monovalent cations for both activation and stabilization. NaCl, the best stabilizer, is ineffective as activator; NH(4)Cl, the best activator, is a poor stabilizer. These results support the idea that the roles of salts in both processes are different.

Let A be a finite dimensional complex vector space with a polynomial action of G = GLk. One main example is A = Sym C. (For tensors G = GLk, A = ⊗C) Let Z ⊆ A be locally closed. One main example is a group orbit Z = Gv. Recall (last semester, Chapter 15) that for a locally closed set Z ⊆ A we defined the coordinate ring C[Z] as the ring of regular functions (i.e., locally defined by rational fu...

We consider closed, Weyl-transitive groups of automorphisms of thick buildings. For each element of such a group, we derive a combinatorial formula for its scale and establish the existence of a tidy subgroup for it that equals the stabilizer of a simplex. Simplices whose stabilizers are tidy for some element of the group are characterized in terms of the minimal set of the isometry induced by ...

In this paper nondegenerate multidimensional matrices of boundary format in V0 ⊗ · · · ⊗ Vp are investigated by their link with Steiner vector bundles on product of projective spaces. For any nondegenerate matrix A the stabilizer for the SL(V0)×· · ·×SL(Vp)action, Stab(A), is completely described. In particular we prove that there exists an explicit action of SL(2) on V0 ⊗ · · · ⊗ Vp such that ...

This paper considers the nucleation and propagation of a normal zone in large composite superconductors, considering the relatively tong time of current redistribution in the stabilizer. A model is proposed for treating the composite as an effective electrical circuit, which yields two diffusion equations for the electric current and the temperature distributions along the conductor. Numerical ...

Self-orthogonal J-affine variety codes have been successfully used to obtain quantum stabilizer codes with excellent parameters. In a previous paper we gave formulae for the dimension of this family of quantum codes, but no bound for the minimum distance was given. In this work, we show how to derive quantum stabilizer codes with designed minimum distance from J-affine variety codes and their s...

The perceived motion of two added sinusoidal gratings of similar amplitude and spatial frequency but different orientations is often coherent. However, when either relative grating contrast or frequency are varied, perception may transform to a motion transparency. For plaids, both multiplicative and additive transparent percepts are reported. To explain perception, several computational models...
