Cycles in economic systems with open labor markets

A dynamic macromodel of an economic system with a monopsonic labor market and variable labor resources is considered. The initiation conditions for classical business cycles are investigated for this model. Bifurcation analysis of the model is performed to estimate the effect of the minimum wage on the way such cycles form. The results of theoretical analysis are supplemented with numerical experiments. __________ Translated from Kibernetika i Sistemnyi Analiz, No. 4, pp. 48–72, July–August 2008.     

带种族遗传算法的神经网络辨识器及其应用

为了解决油田动态系统建立数字模型难和模型训练难的问题,以多层动态前向网络为模型框架,给出了一种新的油田系统神经网络辩识器,它对上述系统具有通用性。为了训练该辩识器和避免极值问题,模拟生物种族进化机制,设计了新的种族遗传算法。该算法是由改进的带共享机制的遗传算法、启发式山峰聚类算法和新的Powell算法有机结合构成的新型混合算法。应用表明,种族遗传算法具有极强的全局和局部搜索能力,这确保了上述神经网络辩识器具有很高的预测精度,平均相对误差在1%以内。

Dynamic Control of Walking Cycle with Initiation Process for Humanoid Robot

This paper focuses on numerical method to solve the dynamic equilibrium of a humanoid robot during the walking cycle with the gait initiation process. It is based on a multi-chain strategy and a dynamic control/command architecture previously developed by Gorce. The strategy is based on correction of the trunk center of mass acceleration and force distribution of the forces exerced by the limbs on the trunk. This latter is performed by mean of a Linear Programming (LP) method. We study the gait initiation process when a subject, initially in quiet erect stance posture, performs a walking cycle. In this paper, we propose to adjust the method for the multiphases (from double support to single support) and multicriteria features of the studied movement. This is done by adapting some specific constraints and criteria in order to ensure the global stability of the humanoid robot along the task execution. For that, we use a Real-Time Criteria and Constraints Adaptation method. Simulation results are presented to demonstrate criteria and constraints influences on the dynamic stability.
