synthesis of platinum nanostructures in two phase system
چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
Fixing of Cycle Slips in Dual-Frequency GPS Phase Observables using Discrete Wavelet Transforms
The occurrence of cycle slips is a major limiting factor for achievement of sub-decimeter accuracy in positioning with GPS (Global Positioning System). In the past, several authors introduced a method based on different combinations of GPS data together with Kalman filter to solve the problem of the cycle slips. In this paper the same philosophy is used but with discrete wavelet transforms. For...
متن کاملIntroduction To Phase-Lock Loop System Modeling
Phase-lock loops (PLLs) have been one of the basic building blocks in modern electronic systems. They have been widely used in communications, multimedia and many other applications. The theory and mathematical models used to describe PLLs come in two types: linear and non-linear. Non-linear theory is often complicated and difficult to deal with in real-world designs. Analog PLLs have been well...
متن کاملThe lock-in phase in the urotropine-sebacic acid system.
The 1,10-decanedioic acid-1,3,5,7-tetraazatricyclo[3.3.1.1(3,7)]decane (1/1) system, C(10)H(18)O(4).C(6)H(12)N(4), was studied at 215 (2) K. Its analysis provides important information with regard to the long-standing acid-carboxylate controversy in the urotropine-alkanedioic acid system. In the present structure, all the chain end-groups display a clear acid character. The asymmetric unit of t...
متن کاملHybrid Modelling and Limit Cycle Analysis for a Class of Five-phase Anti-lock Brake Algorithms
The aim of our paper is to provide a new class of five-phase anti-lock brake algorithms (that use wheel deceleration logic-based switching) and a simple mathematical background that explains their behavior. Firstly, we completely characterize the conditions required for our algorithm to work. Secondly, we explain how to compute analytically an approximation of the Poincaré map of the system (wi...
