Dust in the host galaxies of gamma-ray bursts (GRBs) dims and reddens their afterglow spectra. Knowledge of the nature of this dust is crucial for correcting for extinction, providing clues to the nature of GRB progenitors, and probing the interstellar medium of high-redshift galaxies as well as the nature of cosmic dust when the universe was much younger and galaxies were much less evolved. Th...

IMPLEMENTATION AND EVALUATION OF DISPERSION-INVARIANT FEATURES FOR SIGNAL CLASSIFICATION Greg Okopal, M.S. University of Pittsburgh, 2007 When a sound wave interacts with an object, the acoustic energy may excite resonances in the object corresponding to its natural modes of vibration. The backscattered wave will then contain information which can be used to distinguish among different objects....

AbsrractConventional fuzzy logic controller uses input membership functions that consist of identical triangular input membership functions (MF) for all the subsets that are not located at the two ends of the universal set (center width constant or CWC). Some researchers in the field of motor controllers have started using narrower base triangular membership functions for the input subsets that...

با ظهور جدیدترین مرحله سرمایه داری یا به گفته فرانکو بیفو براردی، عصر "نشانه-سرمایه داری"، شاهد تغییرات زیادی در بستر اقتصادی، اجتماعی و سیاسی جوامع بوده ایم. مقاله حاضر تلاش می کند چنین بستری تکیه بر نظریات براردی برخی از عناصر موضوعی ساختاری رمان های دیوید فاستر والاس را عنوان یکی شاخص ترین نویسندگان پسا پست مدرن آمریکایی مورد بررسی قرار دهد. این امر تحلیل امکان ماهیت مشارکت نظر گرفتن تاثیرسا...

مکانیزم شکست ناشی از خزش در طی حادثه شدید یک رآکتور‌ آبی‌تحت‌فشار به‌جهت انتقال مواد رادیواکتیو به محیط‌زیست اهمیت ویژه‌ای برخوردار است. دنبال شدید، حرارت واپاشی منتقل‌شده سایر قسمت‌های سیستم‌خنک‌کننده رآکتور می‌تواند منجر گرم‌شدن سازه‌های سیستم خنک‌کننده (RCS) و خرابی نواحی تحت‌فشار آسیب‌پذیر شود. قطع‌کامل‌برق (SBO) بدون اقدامات اپراتور (توالی TMLB) یکی محتمل‌ترین سناریوهایی است که ممکن یکپارچ...

Recent development of Enlist corn allows the use 2,4-D choline (Enlist One), glyphosate (Roundup PowerMax), glufosinate (Liberty), and aryloxyphenoxypropionate (FOPs) herbicides for controlling grass broadleaf weeds. However, volunteer plants can cause infestation in subsequent E3 soybean (resistant to 2,4-D, glyphosate, glufosinate) areas where a corn-soybean rotation is commonly practiced. Th...

Insomnia is one of the most common health problems and has recently been re-termed 'Disorders of initiating and Maintaining Sleep', or DIMS. The main purpose of the present study was to investigate the relationship between daily psychosocial stressors, to which workers are exposed in occupational and/or private life, and insomnia among male industrial workers in a medium-sized company located i...

Understanding plasma etch damage on near-surface nitrogen vacancy (NV) centers in diamond is essential for preserving NV emission in photonic structures and magnetometry systems. We have developed a methodology to compare the optical properties of ensemble NV centers initially 70 nm from the surface brought closer to the surface through etching with O2 plasmas in three different reactors. We em...

Bioactive peptides play critical roles in regulating most biological processes in animals. The elucidation of the amino acid sequence of these regulatory peptides is crucial for our understanding of animal physiology. Most of the (neuro)peptides currently known were identified by purification and subsequent amino acid sequencing. With the entire genome sequence of some animals now available, it...
