Robust and efficient solution techniques for solving macroeconometric models are increasingly becoming a key factor in developing models employed by policy-making institutions for policy simulations and forecasting. Traditionally, when solved in presence of forward-looking variables, these models are nonlinear, large-scale and sparse and give rise to large and highly structured nonlinear system...

THE methods employed by Hunter and Eagles [1925], by Benedict, Newton and Behre [1926], and by Benedict and Newton [1929] for the isolation of ergothioneine from blood are somewhat involved and expensive to apply. The authors have devised a technique (based on Hopkins's [1929] method for glutathione) which yields about 85 % of the ergothioneine present. The method involves three stages. (1) The...

A Newton-Krylov unstructured flow solver is developed for higher-order computation of the Euler equations using an upwind scheme. The Generalized Minimal Residual (GMRES) algorithm is used for solving the linear system arising from implicit time discretization of the governing eqautions. An Incomplete Lower-Upper factorization technique is employed as the preconditioning strategy, and an approx...

A technique for maintaining the positive definiteness of the matrices in the quasi-Newton version of the SQP algorithm is proposed. In our algorithm, matrices approximating the Hessian of the augmented Lagrangian are updated. The positive definiteness of these matrices in the space tangent to the constraint manifold is ensured by a so-called piecewise line-search technique, while their positive...

Identifying abnormalities or anomalies by visual inspection on neurophysiologic signals such as ElectroEncephaloGrams (EEGs), is extremely challenging. We propose a novel Multi-Dimensional Time Series (MDTS) classification technique, called Connectivity Support Vector Machines (C-SVMs) that integrates brain connectivity network with SVMs. To alter noise in EEG data, Independent Component Analys...

Objective:Mold contamination of cakes and the possibility of mold growth can pose a serious health problem. Bakery products include various ingredients, which regularly contain molds. These microorganisms on cakes can come from the air, contaminated packaging materials and other sources.Methods: In this study, a total of 500 fungal isolates representing 36 species, were identified from cake sam...
