Recurrent networks that have transfer functions that fulfill the Lipschitz continuity with L = 1, may be echo state networks if certain limitations on the recurrent connectivity are applied. Initially it has been shown that it is sufficient if the largest singular value of the recurrent connectivity S is smaller than 1. The main achievement of this paper is a proof under which conditions the ne...

A condition based preventive and corrective maintenance policy is proposed for a continuously operating system. The condition of the system is assumed to deteriorate with time. The model incorporates both deterioration as well as random common cause failures. The deterioration stages are modeled as discrete state processes. The system is put to random inspection to know the condition. The mean ...

N.sitophila was grown under controlled conditions of solid state and submerged fermentation on Sago hampas. The optimum conditions of protein enrichment previously established for sugar beet pulp was used for this study. Under this condition the protein content of Sago hampas under solid state increased from 1.4 to 14.45% (W/W) whereas for Sago hampas and Sago starch, the protein content under ...

We investigate the effects of interregional labor market integration on the dynamic interaction between migration and capital formation through changes in house prices. The nature of this interaction depends on initial conditions at the time of labor market integration. In an initially capital-poor economy, there may be a reversal of migration during the transition to the steady state, like obs...

The small open economy model with incomplete asset markets features a steady-state that depends on initial conditions and equilibrium dynamics that possess a random walk component. A number of modifications to the standard model have been proposed to induce stationarity. This paper presents a quantitative comparison of these alternative approaches. Five different specifications are considered: ...
