Detection of Propene in Titan’s Stratosphere
The Voyager 1 flyby of Titan in 1980 gave a first glimpse of the chemical complexity of Titan’s atmosphere, detecting many new molecules with the infrared interferometer spectrometer (IRIS). These included propane (C3H8) and propyne (CH3C2H), while the intermediate-sized C3Hx hydrocarbon (C3H6) was curiously absent. Using spectra from the Composite Infrared Spectrometer on Cassini, we show the ...
متن کاملinvestigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
Copolymerization of propene with low amounts of ethene in propene bulk phase
Propene homopolymers and propene–ethene copolymers with small amount of ethene were synthesized using three catalyst systems [pCH3OPh2C(2,7-diBuFlu)(Cp)]ZrCl2/Me2HNPh][B(C6F5)4] (Cat I), [p-CH3OPh2C(2,7-diBuFlu)(Cp)]ZrCl2/[Ph3C][B(C6F5)4] (Cat II) and [p-CH3OPh2C(2,7-diBuFlu)(Cp)]ZrCl2/MAO (Cat III) in propene bulk phase. The activity of the catalyst was dependent on the formed ion pair: Cat I ...
متن کاملRECOD Titans at ISIC Challenge 2017
Our team has worked on melanoma classification since early 2014 [1], and has employed deep learning with transfer learning for that task since 2015 [2]. Recently, the community has started to move from traditional techniques towards deep learning, following the general trend of computer vision [3]. Deep learning poses a challenge for medical applications, due to the need of very large training ...
متن کاملPreparation of 1-C14-propene-1 and the mechanism of permanganate oxidation of propene.
. l-C14_propene~1 has been prepared. The migration of the double bond under a variety of experimental conditions in the preparation of propene has been investigated. 'rhe mechanism of the permanganate oxidation of the labelled propene has been examined; it has been found to proceed by several paths, the relative importance of which depends upon the experimental conditions .. especia lly the pH....
