all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
We use a nonperturbative method based on quantum averaging and an adapted from of resonant transformations to treat the resonances of the Hamiltonian of a two-level atom interacting with a one-mode classical field in Floquet formalism. We illustrate this method by extraction of effective Hamiltonians of the system in two regimes of weak and strong coupling. The results obtained in the strong-...
The buried hetero-structure (BH) InGaAsP-InP waveguide is used for asystem of double microring resonators (DMR). The light transmission and location ofresonant peaks are determined for six different sets of ring radii with different ordermode numbers. The effect of changing middle coupling coefficient on the box likeresponse is studied. It is found that the surge of coupling coefficient to the ...
Service coupling is the key process to SOA Projects. Cooperation in the process of the service coupling is the main non-technical factors to the success of SOA Projects. In this paper, the system dynamic model is established basing on the cooperation factors between SOA project team and ESB suppliers in the process of service coupling; some factors are analyzed to the dynamic influence of the p...
one of the most important factors in study of project’s , is the study of environmental opportunities factors the permanent study of environmental opportunity factors . the study of permanent environmental changing and knowing golden threats’ cooperate with possible threats and at the result in structure forming and future skeleton of organization has a vital effects . the petrochemical industr...
in this paper deflection and free vibration of sandwich panel is studied. the core of sandwich panels is made of hexagonal honeycomb and faces are made of two different materials of carbon fiber reinforced plastic and k-aryl/epoxy covering. the governing equations are deduced from the first order sheer deformation theory (fsdt) and they are solved using generalized differential quadrature metho...
the catalytic acvtivity of dimeric and monomeric ortho-palladated complexes [pd{c6h2(ch2nh2-(ome)2,3,4}(µ-cl)]2)2) and [pd{c6h2(ch2nh2-(ome)2,3,4}cl(pph3)](3), was investigated in heck cross-coupling reaction. these complexes are more active and efficient catalysts for heck cross-coupling reaction. the palladium complexes 2 and 3 is employed in the heck cross-coupling reaction between styrene a...
Coupling capacitance has substantial impact on signal delays and arrival times. It is not always correct to de-couple them using the Miller Factors of 0 or 2X. Towards this end various de-coupling techniques have been studied in literature. We extend them and suggest their use in static timing analysis. Our approach uses the Switching Factor based de-coupling approximation idea to compute impac...
finite and boundary element methods have been used by many authors to solve mathematicalphysics problems. however, the coupling of these two methods happens to be more efficient as it combinestheir merits. in this paper, the mathematical analysis of the coupling of finite and boundary element methodsfor the helmholtz equation is presented.
واکنشهای چند جزئی (mcrs) یکی از روش¬های جالب برای سنتز ساختارهای مولکولی متعدد و افزایش تنوع ساختاری و اسکلتی از مولکول¬های ساده و قابل دسترس می¬باشد. فعالسازی پیوند c–h آلکین¬های انتهایی به¬وسیله کاتالیزگرهای فلزی یک روش اساسی در سنتز آلی است. یکی از بهترین مثال¬ها برای این روند، تراکم سه جزئی آلدهید، آلکین و آمین است) (a3-coupling.. در این تحقیق واکنش سه جزئی آلدهید، آلکین و آمین، در حضور کات...
