This paper is constructed with the effort of development of controlled system on the application of a traditional Zeigler-Nichols (Z-N) tuning method implemented for a boiler-turbine power plant to achieve better efficiency of the system. Extensive study and analysis of the state space representation to mathematical modeling approach is developed for the system introducing simulation method. A ...

We give a model of the K-ring of the flag varieties in terms of a certain braided Hopf algebra called the Nichols-Woronowicz algebra. Our model is based on the construction of the path operators by C. Lenart and A. Postnikov.

Genetic relationships among two strains of Treponema pallidum (Nichols and KKJ) and a strain of T. pertenue were determined by measuring the degree of deoxyribonucleic acid sequence homology. The results in indicated that these three virulent, noncultivable treponemes were genetically indistinguishable. Like T. pallidum (Nichols), T. pertenue (Gauthier) had no detectable deoxyribonucleic acid s...

Venous blood is necessary for the estimation of the erythrocyte sedimentation rate (E.S.R.) by the methods of Westergren (1921) and Wintrobe and Landsberg (1935), but venepuncture may occasionally prove difficult or impossible, owing to such factors as inadequate veins, obesity, and flexion deformities. A search was therefore undertaken for a reliable method of estimating the E.S.R. using capil...

We show that every finite GK-dimensional pre-Nichols algebra for braidings of diagonal type with connected diagram modular, supermodular or unidentified is a quotient the distinguished introduced by first-named author, up to two exceptions. For these exceptional cases, we provide substitutes one in sense it projects onto all algebras. build both as non-trivial central extensions GK-dimension co...

This document was originally submitted as an internet draft in November of 1997. As one of the documents predating the formation of the IETF’s Differentiated Services Working Group, many of the ideas presented here, in concert with Dave Clark’s subsequent presentation to the December 1997 meeting of the IETF Integrated Services Working Group, were key to the work which led to RFCs 2474 and 2475...

We compute liftings of the Nichols algebra of a Yetter-Drinfeld module of Cartan type B2 subject to the small restriction that the diagonal elements of the braiding matrix are primitive nth roots of 1 with odd n 6= 5. As well, we compute the liftings of a Nichols algebra of Cartan type A2 if the diagonal elements of the braiding matrix are cube roots of 1; this case was not completely covered i...

This paper focuses on simultaneous relay auto tuning of open loop unstable parallel cascade systems. For stable parallel cascade systems,Vivek and Chidambaram[1] had discussed effect of higher order harmonics of symmetrical relay output, which accounts for error in ultimate controller gain estimation. In the present work, this method is extended to parallel cascade controllers for open loop uns...
