Fundamental Frequency Estimation in Power Systems Using Complex Prony Analysis

남순열,이동규,강상희,안선주,최준호 대한전기학회 2011 Journal of Electrical Engineering & Technology Vol.6 No.2

A new algorithm for estimating the fundamental frequency of power system signals is presented. The proposed algorithm consists of two stages: orthogonal decomposition and a complex Prony analysis. First, the input signal is decomposed into two orthogonal components using cosine and sine filters, and a variable window is adapted to enhance the performance of eliminating harmonics. Then a complex Prony analysis that is proposed in this paper is used to estimate the fundamental frequency by approximating the cosine-filtered and sine-filtered signals simultaneously. To evaluate the performance of the algorithm, amplitude modulation and harmonic tests were performed using simulated test signals. The performance of the algorithm was also assessed for dynamic conditions on a singlemachine power system. The Electromagnetic Transients Program was used to generate voltage signals for a load increase and single phase-to-ground faults. The performance evaluation showed that the proposed algorithm accurately estimated the fundamental frequency of power system signals in the presence of amplitude modulation and harmonics.

Background and objectives : The various voice-conserving treatments are used for Tla staged glottic cancer. Especially, Tla staged glottic cancer has been shown excellent treatment result after laser cordectomy or radiotherapy. To evaluate which treatment results better voice after treatment made it valuable to define the exact indication and recommending treatment modality on the Tla staged glottic cancer patients. Method : The medical records of 75 patients with glottic TlaN0 cancer diagnosed at Asan medical center, University of Ulsan college of medicine form May, 1989 to July,2001 were retrospectively reviewed on the point of voice quality and oncology including 5-year survival rate and local control rate. Results : Laser cordectomy and radiotherapy showed 100% and 94.0% 5-year survival rate, respectively. And laser cordectomy had 94.3% local control rate while radiotherapy got 87.6% local control rate. Voice analysis of pretreatment and posttreatment were used to compare each result. Fundamental frequency(F0), shimmer, jitter, noise to harmony ratio(NHR), maximum confortable phonation time(MPT) and vocal efficiency(VE) were used for parameters for voice analysis. Only in shimmer and MPT, we could find significant posttreatment difference between two therapies. In addition, we reviewed the total expenses for each therapy. Conclusion : On the basis of the oncologic result, both the laser cordectomy and radiotherapy had the similar results. Laser cordectomy showed the relatively acceptable voice as radiotherapy did. Laser cordectomy cost less than radiotherapy did. Laser cordectomy can be used for treatment about Tla staged glottic cancer.

Aims of study : The purpose of this study is to measure the chronic and daily voice burden of the professionals in their actual working places. These will be a valuable guideline for preventing and controlling the voice production of professionals. Material and method : Our study was selected to the 10 female telephone operators in the Asan Medical Center, ages ranging from 22 to 38 years old. The symptoms and acoustic analysis of both telephone operators and the controls were evaluated before and after their working. The symptoms were evaluated with questionaires, and the acoustic analysis was measured by using CSL (computerized speech laboratory) system. Results : The symptoms of the professional voice abusers are same as those symptoms in laryngeal fatigue. The acoustic analysis before their working were significantly increased in jitter and shimmer, in comparison with the data of the control. This shows that the experimental group is exposed to the chronic burden of voice production. The jitter, shimmer, and NHR after their working are significantly increased in comparison with the data of the acoustic analysis before their working. This also shows that the experimental group is exposed to the daily burden of voice production. Conclusion : The acoustic analysis of the professional voice overusers has objectively measured that there are chronic and daily overloading to the voice of operators, and these will be a valuable data for preventing and controlling the professionals that abuse their voice.

The term laryngopharyngeal reflux (LPR) refers to the backflow of food or stomach acid back up into the larynx (the voice box) or the pharynx (the throat). Esophagopharyngeal reflux is suggested as an etiologic factor in laryngeal disease. To examine a possible esophageal basis for laryngopharyngeal symptoms, we studied 48 patients with persistent laryngopharyngeal symptoms, and 12 relative control subjects. Patients were evaluated for cervical symptoms by questionnaire and underwent gastrofiberoscopy, fiberoptic laryngoscopy, esophageal manometry and 24-hour ambulatory double-probe pH monitoring. We found LPR in fourteen out of 48 patients with cervical symptoms (29%). The LPR group consisted of nine men and five women. The symptoms that LPR patients complained were throat lump sensation, hoareness, sore throat, throat clearing, chronic coughing and dysphagia in order of frequency, and they were not different significantly from non-LPR patients. The laryngoscopic findings in LPR patients were posterior erythema, laryngeal edema and diffuse erythema, and there was also no significant difference between LPR group and non-LPR group. There was statistically significant correlation between LPR and gastroesophageal reflux (GER). We concluded that there is no pathognomonic symptoms or laryngoscopic findings in diagnosis of LPR, and 24-hour ambulatory double-probe pH monitoring is an essential diagnostic tool in LPR.

Wister백서를 대상으로 26례의 동종 후두이식을 하였다. 공여 백서의 우측 경동맥을 수혜백서의 좌측 경동맥과 10.0prolene으로 여덟 봉합하고, 공여백서의 좌측 경동맥을 수혜백서의 외경정맥과 꼬이지 않게 10.0prolone으로 여섯 봉합을 실시하고 우측 반회신경도 수혜백서의 좌측 반회신경과 10.0prolene 한봉합을 실시하였고 마지막 2례의 기능적 회복을 보인 경우는 위에 정맥이식(vein graft)도 같이 실시하였다. 술후 수시간이내 두마리가 죽고 4례는 술후 2주이내 죽었으며, 나머지 20례중 3개월까지 추적 가능하였던 13례중 7례는 공여 후두가 소실 되었고 3례는 심한 근육위축을 보였으며 1례는 외견상 정상이었으나 기능을 보이지 않았으며 마지막 2례에서 기능적 회복을 보였다. 본 연구의 백서에서 기능적회복은 인간에서의 후두이식을 대비하여 기초가 될 것이다. Differing from other organs, the success of vascular reanastomosis and funtional reinnervation including voice are important to laryngeal transplantation. 26 cases of the Wister rat (250-300gm) were performed. The donor's right common carotid and recipient's left common carotid artery were connected by 8 stitches 10.0 prolene. The donor's left common carotid artery and recipient's left external jugular vein were connected by 6 stitches 10.0 prolene. The recurrent laryngeal nerves were connected by 1 stitch 10.0 prolene. The last two cases which showed reinnervation were connected by 1 stitch with vein graft. The results were as follows; 1) 2cases died within 2 hours. 2) 4 cases died within 2 weeks. 3) 13 cases which can be followed for 3 monthes. 7 cases lost donor larynx. 3 cases showed severe muscular atrophy. 1 case showed intact external appearance, but did not reinnervated. The last 2 cases showed spontaneous movement and reinnervation was identified through glycogen depletion and elctromyography. This study will be a cornerstone preparing for human laryngeal transplantation.
