Among the hierarchy of sensors, the distributed fiberoptic temperature sensor is unique, as it offers continuous sensing over tens of kilometers with good temperature accuracy and high spatial resolution. Distributed temperature sensors (DTS's) that use Raman scattering as the sensing mechanism have already been reported.`-4 More recently, the variation with temperature of the Stokes frequency ...

The genus g of an Fq2-maximal curve satisfies g = g1 := q(q − 1)/2 or g ≤ g2 := ⌊(q − 1) /4⌊. Previously, Fq2 -maximal curves with g = g1 or g = g2, q odd, have been characterized up to Fq2 -isomorphism. Here it is shown that an Fq2 -maximal curve with genus g2, q even, is Fq2 -isomorphic to the nonsingular model of the plane curve ∑t i=1 y q/2 = x, q = 2, provided that q/2 is a Weierstrass non...

In this paper a new threephase multi-level inverter topology is proposed. With the increasing requirements for high power at high power quality, such a converter is inevitable. The major advantages of the proposed topology are improved power quality and lesser number of switches. This leads to lesser complexity of the control circuitry, reduction in switching harmonics and reduction in the cost...

Three-level Z-source inverters are recent single-stage topological solutions proposed for buck-boost energy conversion with all favorable advantages of three-level switching retained. Despite their effectiveness in achieving voltage buck-boost conversion, existing three-level Z-source inverters use two impedance networks and two isolated dc sources, which can significantly increase the overall ...

Although it has been postulated that glyoxylate is an intermediate in the biotransformation of DCA to oxalate, CO2, and glycine, there has been no positive identification of glyoxylate as a metabolite of DCA. We have demonstrated that a GSH-dependent pathway in dialyzed hepatic cytosol from rats and humans converts a mixture of 1-Cand 1,2-C-DCA to isotopically labeled glyoxylate. The reaction d...
