25. Observability analysis for state and parameter estimator / Análise de observabilidade para o estimador de estados e parâmetros do sistema elétrico
Neste trabalho propõe-se um método de análise de observabilidade para estimação de estados e parâmetros em sistemas elétricos de potência, baseado nas equações normais. O método fundamenta-se na fatoração triangular da matriz ganho aumentada e nos conceitos de caminhos de fatoração. O mesmo utiliza rotinas já existentes no processo de estima�

26. A Numerical and Experimental Evaluation of ERA and ERA/OKID for Mechanical Systems Identification / Avaliação numérica e experimental dos métodos ERA e ERA/OKID para a identificação de sistemas mecânicos
This work presents two algorithms of identification of state-space linear systems, as follows: ERA (Eigensystem Realization Algorithm), developed by Juang and Pappa (1985), and ERA/ OKID (Observer/ Kalman Filter Identification), by Phan et al. (1992). Both were conceived at the environment of Aerospace Engineering, where it was indispensable the appearance o

28. The Black–Scholes pricing formula in the quantum context
A natural explanation for extreme irregularities in the evolution of prices in financial markets is provided by quantum effects. The lack of simultaneous observability of relevant variables and the interference of attempted observation with the values of these variables represent such effects. These characteristics have been noted by traders and economists a

29. NMR structures of three single-residue variants of the human prion protein
The NMR structures of three single-amino acid variants of the C-terminal domain of the human prion protein, hPrP(121–230), are presented. In hPrP(M166V) and hPrP(R220K) the substitution is with the corresponding residue in murine PrP, and in hPrP(S170N) it is with the corresponding Syrian hamster residue. All three substitutions are in the surface region o

30. Proton nuclear magnetic resonance of spin-labeled Escherichia coli tRNAf1MET.
Thiouridine at position 8 (s4U8) of tRNAf1Met was spin-labeled with the nitroxide free radical, N-(1-oxyl-2,2,5,5-Tetramethyl-3-pyrrolidinyl) bromacetamide, for proton nuclear magnetic resonance spectroscopic studies. The well-resolved methyl peak of ribothymidine is unperturbed, but the peak tentatively assigned to the C-5 methylene group of dihydrouridine
