in this work, thermal degradation behavior of a fuel-rich energetic mixture containing epoxy binder was studied by thrmogravimetric analysis and differential scanning calorimetry under dynamic nitrogen atmosphere at different heating rates. variation of the thermal degradation activation energy of the mixture was evaluated by differential and integral isoconversional methods via akts software p...
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
نامساوی ها یکی از مهمترین حوزه های پژوهشی آنالیز ماتریسی هستند که از ابتدا مورد علاقه بسیاری از ریاضی دانان بوده و کاربردهایی در علوم مختلف از جمله محاسبات علمی، نظریه سیستم و کنترل، تحقیق در عملیات، فیزیک ریاضی، استاتیک، اقتصاد و مهندسی دارد. نخستین بار در سال $1934$ کتاب تقریبا جامعی با نام "نامساوی ها" cite{h} توسط هاردی، ltrfootnote{g. h. hardy} لیتل وود ltrfootnote{e. little...
برگروه لی$ g=so_{0}(n,1) $، یک متریک ناوردای چپ تعریف می شود که از فرم کیلینگ-کارتان بدست می آید. زیرگروه فشرده همبند بیشین آن عبارت است از $ so(n)=so(n) imeslbrace 1 brace $که با$ k $ نمایش می دهیم.گروه طولپایی های$ g $ عبارت است از egin{equation*} isom_{0}(g)=g imes k, end{equation*} یعنی ضرب چپ توسط عضو های$ g $ و ضرب راست توسط عضو های $ k $. بنابراین، دو عمل برای $ k...
Abstract: In this research work, crystallization kinetics of Fe55Cr18Mo7B16C4 alloy was evaluated by X-ray diffraction, TEM observations and differential scanning calorimetric tests. In practice, crystallization and growth mechanisms were investigated using DSC tests in four different heating rates. Results showed that a two -step crystallization process occurred in the alloy in which - Fe phas...
Through isoconversional analysis of differential scanning calorimetry data, thermally induced processes glass transition and crystallization in Cux(As2Se3)100-x chalcogenide glasses (x=1, 5, 10, 15 at.%) were investigated. The characteristic values activation energy its changes during the calculated using advanced method developed by S. Vyazovkin as well forms Kissinger Moynihan relations. resu...
Sodium alanate (NaAlH4) is a prospective H2 storage material for stationary and mobile applications, as NaAlH4 contains 7.4 wt% of H2, it possible to do multiple release accumulation cycles. Nanoconfinement potential solution enhance the properties NaAlH4. To optimize supporting synthesis method used nanoconfinement NaAlH4, better understanding influence on processes necessary. Thus, from bulk,...
Bu çalışmada, Al85Ni5Fe5Nd5 (at.%) alaşımı hızlı katılaştırma yöntemi ile ince şeritler halinde ve mekaniksel alaşımlama tozlar elde edilmiştir. Alaşımların morfolojik yapısı, faz tanımlaması, parçacık boyutu parçacıkların dağılımı gibi yapısal özellikleri X-ışını difraksiyonu (XRD) taramalı elektron mikroskobu (SEM) kullanılarak incelenmiştir. kristalleşme sıcaklıkları, aktivasyon enerjisi dön...
We live in a time of uncertainty and transition. Some would claim that Enlightenment has already died (Kissinger, Bendyk 2018, Agata Bielik-Robson 2019), its values are no longer relevant to our values. However, quite recently, some outstanding scientists, like Steven Pinker (2018), have published good defence the Enlightenment, claiming instead we need What follows is quick overview defences f...
