Microwave assisted synthesis of [4, 5-e] [1, 3, 4]thia- diazin-7-yl] hydrazine Derivatives

New pyrimido [4, 5-e] [1, 3, 4]thia- diazin-7-yl] hydrazines were synthesized via the cyclocondensation of alkyl-2-phenylhydrazinecarbodithioates as a binucleophile with 5-bromo-2,4-dichloro-6-methylpyrimidine as a bielectrophile , and replacement of C-7 chloro atom by hydrazine in ethanol as the solvent . This method has advantages over methods currently described in the literature for the con...

A decentralized failure detection and isolation (FDI) methodology, which is robust with respect to model uncertainties and noise, is presented. Redundancy metrics are developed, and optimization problems are posed for the choices of robust parity relations. Closed-form solutions for some special failure cases are given. Connections are drawn with other disciplines, and the use of the metrics to...

A 1 - TO 5 - MW , RCS - BASED , SHORT - PULSE SPALLATION NEUTRON SOURCE caN / ~ 7 7 0 50 3 - - / 3 7

Ahstrucl Two accelerator configurations, the linac/compressor ring scheme and the Iinac/RCS scheme, are commonly used to provide the proton beam power for a short-pulse spallation neutron source. In one configuration, a fullpower linac provides the beam power and a compressor ring shortens the pulse length from I-ms down to 1 p. In the other, rapid cycling synchrotrons (RCSs) provide the beam p...

Based on the frequent requests for help that I have received in the past months from users who want to configure TEX or LTEX for typesetting in several languages, it seems that this sort of information is not adequately covered in the documentation available to most do-it-yourself users. This tutorial is intended to give basic information on this topic. The related subject of hyphenation patter...
