Introduction: An fMRI study is ideally acquired at a high temporal resolution and with full brain coverage at each scan time point. This prerequisite is especially true in view of the rapid dynamic BOLD signal changes expected when cognitive tasks are studied. A cascade like brain recruitment is typically observed in complex mental exercises where neural recruitment occurs in both parallel and ...

We present a progress report on our study of the charmonium spectrum in full QCD on anisotropic lattices generated by the Hadron Spectrum Collaboration. We adopt a large basis of interpolating operators to extract the excited charmonium states using the variational method. A detailed spectrum of excited charmonium mesons in many JPC channels is obtained. Hybrid states with exotic and non-exotic...

Time correlation functions for an exotic hybrid meson, J PC £ 1¤ ¦ ¥ , are analyzed using the maximum entropy method (MEM). The MEM analysis provides both ground and excited state energies. Both the location and strength of each spectral mass density peak are determined when a simulated annealing process is employed with the MEM analysis. We extract ground and excited states of about 1.4, 1.6, ...

Slip power recovery configuration provides an attractive alternative for variable speed drives and generating systems, due to its high-efficiency and low converter rating. The core component is the doubly-excited machine. Firstly, we present a stability analysis of the doubly-excited machine with open loop voltage and open loop current control in the rotor circuit. Possibilities of open loop co...

Variable speed constant frequency generating systems are used in wind power, hydro power, aerospace and naval power generations to enhance efficiency and reduce friction. In these applications, an attractive candidate is the slip power recovery system comprising of doubly-excited induction machine or doubly-excited brushless reluctance machine and PWM inverters with dc link. In this paper, a fl...

  In this paper flexible job-shop scheduling problem (FJSP) is studied in the case of optimizing different contradictory objectives consisting of: (1) minimizing makespan, (2) minimizing total workload, and (3) minimizing workload of the most loaded machine. As the problem belongs to the class of NP-Hard problems, a new hybrid genetic algorithm is proposed to obtain a large set of Pareto-optima...
