We show that the typed region calculus of Tofte and Talpin can be encoded in a typed -calculus equipped with name groups and a novel e ect analysis. In the region calculus, each boxed value has a statically determined region in which it is stored. Regions are allocated and deallocated according to a stack discipline, thus improving memory management. The idea of name groups arose in the typed a...
مدرس آینده یک "اجرا گر متفکر" است "متخصصی " که قابلیت تجزیه و تحلیل های ظریف در شرایط متفاوت تدریس را دارد و برای رسیدن به این دو خصوصیت ، نه تنها او باید به زبان فرانسه تسلط کامل داشته باشد ، بلکه نیاز مند به فراگیری آگاهی ها و مهارت های خاص استفاده صحیح و بجا از دانسته هایش و تسلط کامل به دانش های علمی - فرهنگی اجرایی زبان است . لازم به ذکر است که یک استاد" متفکر" همیشه در حال تکمیل و تکامل آ...
Discretionary Access Control (DAC) systems provide powerful resource management mechanisms based on the selective distribution of capabilities to selected classes of principals. We study a type-based theory of DAC models for a process calculus that extends Cardelli, Ghelli and Gordon’s pi-calculus with groups (Cardelli et al., 2005). In our theory, groups play the rôle of principals, the unit o...
Outcrops of the Upper Ordovician igneous rocks, as basaltic lava and microgabbroic dyke and sill, present within the Abarsej and Ghelli formations in north and southwest of Shahrood. These rocks have basaltic, trachybasaltic and basaltic trachyandesitic composition with alkaline nature. Their parallel patterns on the primitive mantle and chondrite normalized spider diagrams indicate the common ...
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
the hydrolysis of cadmium nitrate was studied spectrophotometrically at different ionic strengthsof sodium perchlorate in a wide ph range, 1-12, and at 25 c. least squares calculations areconsistent with the formation of m(oh)+, m(oh)2, m(oh)3- and m(oh)42- species, which m iscd2+. the dependency on ionic strength in the background electrolyte solutions was taken intoaccount by using a debye-hu...
زمینه و هدف: حفظ انحنای کانال ضمن آماده نمودن آن از اهمیت ویژه ای برخوردار است. در درمانهای اندودنتیک همیشه تلاش می شود که شکل نهایی کانال تغییر نکند و کاملاً دربرگیرنده شکل اولیه آن باشد. مطالعه حاضر با هدف تعیین میزان حفظ انحنای کانال در ریشه های داندنهای مولراول بالا و پایین، در موارد درمان ریشه شده و ارزیابی روش step- back به عنوان روش کلاسیک در آماده سازی این دندانها انجام شد.روش بررسی: طی ...
the main purpose of this research paper is to compare qiujiahe formation (є1q) and longmaxi formation (s1ln) in north sichuan basin where shale gas exploration has not been fully researched, and hence represents the possibility of shale gas concentration under the complex geological conditions. based on valid laboratorial analysis, there are optimistic prospects for є1q and s1ln of research are...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
understanding the performance and role of each formation in a petroleum play is crucial for the efficient and precise exploration and exploitation of trapped hydrocarbons in a sedimentary basin. the lorestan basin is one of the most important hydrocarbon basins of iran, and it includes various oil-prone potential source rocks and reservoir rocks. previous geochemical studies of the basin were n...
