Oh, oh was?

Oh, wait, reasoning was wrong! Let's replay

Decision making by real time rule-based reasoners is prone to errors. Modern systems must implement decisions based on partial, statistical, or approximate information. If a part of the information is missing or corrupted, the reasoner might be misled into reaching wrong conclusions. Systems using monotonic static logic are less affected, as they must be more careful in their decisions by desig...

تعیین 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...

Oh 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...

Infrared OH absorption lines in 1612MHz OH maser sources

ISO mid-infrared absorption data helps to distinguish between radiative and collisional pumping mechanisms in 1612MHz OH masers in various environments. Archive data of OH absorption at 34.6 and 53.3 μm shows different behavior and different pumping rates for different types of maser sources. 1. Mid-Infrared absorption in 1612MHz OH masers Mid-infrared spectroscopy by the Infrared Space Observa...
