We present a model of excessive trading based on dynamic and local learning. We analyze how information is aggregated through local interactions, and how such a learning process affects allocations over time. In the absence of private information about the value of the traded asset, the allocation monotonically approaches the effi cient allocation over time. With dispersed private information, ...

We study the energy level statistics of the states in U(5) and O(6) dynamical symmetries of the interacting boson model and the high spin states with backbending in U(5) symmetry. In the calculations, the degeneracy resulting from the additional quantum number is eliminated manually. The calculated results indicate that the finite boson number N effect is prominent. When N has a value close to ...

We consider a quantum system with N degrees of freedom which is classically chaotic. When N is large, and both h̄ and the quantum energy uncertainty ∆E are small, quantum chaos theory can be used to demonstrate the following results: (1) given a generic observable A, the infinite time average A of the quantum expectation value 〈A(t)〉 is independent of all aspects of the initial state other than ...

I determine the scaling behavior of the free energy barriers encountered by a flux line in moving through a three-dimensional random potential. A combination of numerical simulations and analytic arguments suggest that these barriers scale with the length of the line in the same way as the fluctuation in the free energy.

In this paper, we derive stochastic performance bounds under the assumption of exponentially bounded burstiness (EBB) traffic model and exponentially bounded fluctuation (EBF) channel model. Then we propose a measurement-based call admission algorithm providing statistical service level agreement (SLA) guarantee for accepted flows based on the QoS prediction equations for both single and multip...

We present numerical data of the height-height correlation function and of the avalanche size distribution for the three dimensional Toom interface. The height-height correlation function behaves samely as the interfacial fluctuation width, which diverges logarithmically with space and time for both unbiased and biased cases. The avalanche size defined by the number of changing sites caused by ...

In this paper, a method for long-term optimal operation of hydropower station is proposed to control the frequency reservoir level fluctuation. We introduce integer variable which describes rise and fall level, number changes, state transition equation change fluctuation into dynamic programming method. This can obtain global solution under different numbers fall, thus improving controllability...
