The TNO speaker speaker diarization system is based on a standard BIC segmentation and clustering algorithm. Since for the NIST Rich Transcription speaker dizarization evaluation measure correct speech detection appears to be essential, we have developed a speech activity detector (SAD) as well. This is based on decoding the speech signal using two Gaussian Mixture Models trained on silence and...

Topic detection is concerned with the unsupervised clustering of news stories over time. The TNO topic detection system is based on a language modeling approach. For the grouping of stories we combined a simple single pass method to establish an initial clustering and a reallocation method to stabilize the clusters within a certain allowed deferral period. The similarity of an incoming story to...

به علت تغییرات حجم ناشی از خطای ساخت، فرکانس کاواک‌های شتاب‌دهی در شتاب‌دهنده‌های خطی الکترون تغییر می‌کند. نتیجه تنظیم فرکانسی کاواک‌ها یکی مراحل مهم تست سرد است که باید الزامات آن طراحی لحاظ شود. پروژه ساخت ساختار موج‌ایستا برای شتاب­دهنده با دو انرژی، پس طراحی، یک آلومینیمی (شامل نیم کاواک و تزویج) ساخته شد. این جبران پیچ‌های استفاده پیچ‌ها جزیی کاواک‌ها، آن‌ها را می‌دهند. مقاله محاسبات شبیه...

PREFACE This thesis represents a culmination of work and learning that has taken place over a period of over one year (May 2012 until July 2013). It marks the conclusion of my study Civil Engineering and Management at the University of Twente. During the master Traffic Engineering & Management, I received the opportunity to participate in a variety of courses in which several state of the art f...

Context. Recent results suggest that there is a group of trans-Neptunian objects (TNOs) (2003 EL 61 being the biggest member), with surfaces composed of almost pure water ice and with very similar orbital elements. These objects provide exciting laboratories for the study of the processes that prevent the formation of an evolved mantle of organics on the surfaces of the bodies in the trans-Nept...
