Based on PSSMI we developed a new cerebral hemorrhage model and a new system for cerebral hemorrhage detection. This study evaluated experimentally the performance of our system through the simulation of phase shift measurements. Some phase shifts were measured at three operation frequencies. The phase resolution was up to 0.005° and the gain was(More)
Acute cerebral hemorrhage (ACH) is an important clinical problem that is often monitored and studied with expensive devices such as computed tomography, magnetic resonance imaging, and positron emission tomography. These devices are not readily available in economically underdeveloped regions of the world, emergency departments, and emergency zones. We have(More)
Cerebral hemorrhage is an important clinical problem that is often monitored and studied with expensive techniques, such as computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET).

Intracranial hemorrhage (ICH) is the bleeding induced by parenchyma vascular rupture. In this paper, four novel coils (a contralateral hemisphere cancellation coil, a coaxial coil, a double-end exciting coil, and a Helmholtz coil) were developed to detect the volume change of ICH with the magnetic induction phase shift (MIPS) technique. Both numerical(More)
A novel nonreciprocal bandstop filter (NBF) using metamaterial Thue-Morse multiferroic superlattices (MTMMS) is presented, where the multiferroic domains with polarization and magnetization simultaneous are arranged along x-axis according to the iterative rule of the Thue-Morse sequence. The dispersion relation is obtained by the transfer matrix method and(More)
Voice conversion (VC) is the task of modifying a source speaker's voice to match that of a specific target speaker. Traditional methods use Gaussian mixture models (GMM), but the converted speech quality is often badly degraded due to over-smoothing. More recent approaches such as Dynamic Frequency Warping (DFW) maintain more spectrum details during(More)
Cerebral hemorrhage, a difficult issue in clinical practice, is often detected and studied with computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET). However, these expensive devices are not readily available in economically underdeveloped regions, and hence are unable to provide bedside and emergency on-site(More)
