Simulation of 3D moving sound

引用

Chinese journal of Acoustics 1999年第2期18卷 146-151页

作者： QIU Yujing jenison R l Hu Y H Reate R A Brugge j f (Departments of Electrical and Computer Engineering, Psychology, Physiology and Waisman Center, University of Wisconsin-Madison USA WI 53705)

A novel approach to the simulation of 3D sound movement by combining wellknown physical and biophysical cues into a discrete synthesis system is introduced. Physical cues include both the dependence of intensity on distance from the sound source and the Doppler effect. Biophysical features include the direction-dependent transfer functions imposed by a listener's head and ears and interaural time cues. Our technique requires very little disk storage since it relies on Iow-dimensional functional models that relate cue values to arbitrary locations in a virtual space. The system has been implemented on a modern workstation and can synthesize in quasi-real-time movements of arbitrary sound sources and trajectories that are delivered over earphones

Detection of Partial Discharge in Power Transformers Using Rogowski Coil and Multiresolution Analysis

引用

journal of Energy and Power Engineering 2010年第2期4卷 39-45页

Partial discharge detection in power transformers is discussed using a new approach that exploit the broad band of the Rogowski coils and the potential of two signal processing tools： discrete wavelet transform and empirical mode decomposition. Detecting and analyzing incipient activities of partial discharge can provide useful information to diagnostics and prognostics about transformer insulation. So, partial discharge signals embedded in the electric current at ground conductor are measured using the Rogowski coil. These signals are submitted to noise suppression and the partial discharges waveforms are extracted through different ways： using discrete wavelet transform and using empirical mode decomposition. The comparison of these two methods show that the extraction with discrete wavelet transform results in a faster and simpler algorithm than the empirical mode decomposition. But this one produces more precise waveforms due its adaptive characteristic.

Clinical significance of granuloma in Crohn's disease

AIM: Granuloma is considered the hallmark of microscopic diagnosis in Crohn's disease (CD), but granulomas can be detected in only 21-60% of CD patients. The aim of this study was to evaluate the frequency of granulomas by multiple endoscopic biopsies in patients with CD and to examine whether group of patients with or without granuloma exhibit a different clinical course. METHODS: fifty-six patients with newly diagnosed CD were included in the study. jejunoscopy, enteroclysis and ileo-colonoscopy were performed in all patients. At least two biopsy specimens from each examined gastrointestinal segment were examined microscopically searching granuloma. The clinical course was followed in all patients, and extraintestinal manifestations as well as details of any immunosuppressive therapy and surgical intervention were noted. RESUlTS: Granuloma was found in 44.6% of the cases (25 patients). Patients with granuloma had higher activity parameters at the time of the biopsies. Extraintestinal manifestations were observed and surgical interventions were performed more often in the granuloma group. The need of immunosuppressive therapy was significantly more frequent in the patients with granuloma. Granuloma formation is mote often seen in younger patients, and mainly in the severe, active penetrating disease. CONClUSION: The significantly higher frequency of surgical interventions and immunosuppressive therapy suggests that granuloma formation is associated with a more severe disease course during the first years of CD.
