Technological advances and prospects in multimodal neuroimaging
ISBN: 9783659616709 / Angielski / Miękka / 72 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Investigating human brain function can be improved by employing a multimodal functional neuroimaging approach. The fusion of non-invasive electroencephalogram (EEG) and hemodynamic neuroimaging modalities including functional magnetic resonance imaging (fMRI) and functional near-infrared spectroscopy (fNIRS) is able to provide complementary information of brain activity with higher spatiotemporal resolution. To address recent developments in multimodal imaging techniques, algorithms and instrumentations, we first describe the potential and limitations of the presently developed fusion...

Interactions Between Charged Particles in a Magnetic Field: A Theoretical Approach to Ion Stopping in Magnetized Plasmas
ISBN: 9783642442568 / Angielski / Miękka / 187 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This monograph focuses on the influence of a strong magnetic field on the interactions between charged particles in a many-body system. Two complementary approaches, the binary collision model and the dielectric theory are investigated in both analytical and numerical frameworks. In the binary collision model, the Coulomb interaction between the test and the target particles is screened because of the polarization of the target. This monograph focuses on the influence of a strong magnetic field on the interactions between charged particles in a many-body system. Two complem... |

Microgrids: Operation, Control, and Protection
ISBN: 9783659612572 / Angielski / Miękka / 152 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This work proposes a power management and control strategy for islanded microgrids, which consist of multiple electronically-interfaced distributed energy resource (DER) units, to achieve a prescribed load sharing scheme. This strategy provides 1) a power management system, 2) DER local controllers, and 3) a frequency control and synchronization scheme. This strategy is then generalized to incorporate both power-controlled and voltage-controlled DER units. To prevent DER unit trip-out or damage under short-circuit conditions, an overcurrent/overload protection scheme is also proposed. Under...
