The classical cobweb theorem is extended to include production lags and price forecasts. Price forecasting based on a longer period has a stabilizing effect on prices. Longer production lags do not necessarily lead to unstable prices; very long lags lead to cycles of constant amplitude. The classical cobweb requires elasticity of demand to be greater than that of supply; this is not necessarily...

This study constructs a novel four-dimensional fractional-order chaotic system. It verifies chaotic nonlinear dynamic behaviors and physical reliability by numerical simulation and hardware circuit design. For a class of parameter uncertainty fractional different-lags ( i ) chaotic systems, the authors design a time-delayed ( ) synchronization controllers and parameter adaptive laws. It proves ...

In two experiments, we used response signals (RSs) to control processing time and trace out speed--accuracy trade-off(SAT) functions in a difficult perceptual discrimination task. Each experiment compared performance in blocks of trials with constant and, hence, temporally predictable RS lags against performance in blocks with variable, unpredictable RS lags. In both experiments, essentially eq...

In this paper we propose new insights based on an insertion heuristic and generalized resource constraint propagation for solving the job shop scheduling problem with minimum and maximum time-lags. To show the contribution of our propositions we propose a branch-and-bound algorithm and provide an experimental study. The results obtained conclude that our heuristic obtains feasible schedules wit...

This paper compares the observed reverberation response lags and the intensity ratios of the broad line region (BLR) emission lines HeII 1640, HeII 4686 and CIV 1549 with predictions. Published observations indicate that the HeII 1640 lag is three times shorter than the lags of HeII 4686 or CIV 1549. Diverse models however do not reproduce this observation. Extensive improved numerical simulati...

Multielectrode recordings have revealed zero time lag synchronization among remote cerebral cortical areas. However, the axonal conduction delays among such distant regions can amount to several tens of milliseconds. It is still unclear which mechanism is giving rise to isochronous discharge of widely distributed neurons, despite such latencies. Here, we investigate the synchronization properti...

-The paper presents an overview of two recently developed simulation support tools, namely the optimization tool and the sensitivity analysis tool, and demonstrates their use for tuning and analyzing the control system of a static compensator (STATCOM). The optimization tool is used for adjusting the gains and time constants of the control system in order to improve the transient behavior of th...
