Night-sky spectral atlas of OH emission lines in the near-infrared
In this paper, we present medium resolution spectra of the night-sky OH emission. The spectra cover the range 0.997 – 2.25 μm with a resolution of about 8000. Line wavelengths are computed from laboratory data and are given in vacuum. A few lines due to O2 are also identified. This new set of data can be used to calibrate the wavelength scale of spectra obtained in the near-infrared. It can als...
متن کاملNight sweats
Although night sweating is a common outpatient complaint medical, literature on this subject is scarce. Tuberculosis, brucellosis and lymphoma are diseases in which night sweating is a dominant symptom, but these are infrequently found to be the cause of night sweats in modern practice. While these diseases remain important diagnostic considerations in patients with night sweats, other diagnosi...
متن کاملتعیین روش ریزازدیادی پایه‌های همگروه گلابی OH × F333 و OH × F69
این پژوهش به منظور تعیین پروتکل تکثیر درون شیشهای دو پایه همگروه گلابی OH × F69 و OH × F333 در قالب چهار آزمایش مجزا انجام شد. طی آزمایش اول، اثر محیطهای MS ، QL و QL تغییر یافته روی صفات رویشی ساقه‌چه‌های درون شیشه بررسی شد. در بین این محیطها، محیط کشت QL تغییر یافته با بهترین پرآوری و کیفیت شاخه به عنوان محیط کشت پایه برای آزمایشات بعدی انتخاب شد. در آزمایش دوم و سوم ارزیابی اثر دو نوع س...
متن کاملNight Rendering
The issues of realistically rendering naturally illuminated scenes at night are examined. This requires accurate models for moonlight, night skylight, and starlight. In addition, several issues in tone reproduction are discussed: eliminatiing high frequency information invisible to scotopic (night vision) observers; representing the flare lines around stars; determining the dominant hue for the...
متن کاملOh Oh Oh Whoah! Towards Automatic Topic Detection In Song Lyrics
We present an algorithm that allows for indexing music by topic. The application scenario is an information retrieval system into which any song with known lyrics can be inserted and indexed so as to make a music collection browseable by topic. We use text mining techniques for creating a vector space model of our lyrics collection and non-negative matrix factorization (NMF) to identify topic c...
