fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
The aim of this paper is to describe a Matlab toolbox, called μ-diff, for modeling and numerically solving two-dimensional complex multiple scattering by a large collection of circular cylinders. The approximation methods in μ-diff are based on the Fourier series expansions of the four basic integral operators arising in scattering theory. Based on these expressions, an efficient spectrally acc...
Nowadays, the paradigm of parallel computing is changing. CUDA is now a popular programming model for general purpose computations on GPUs and a great number of applications were ported to CUDA obtaining speedups of orders of magnitude comparing to optimized CPU implementations. Hybrid approaches that combine the message passing model with the shared memory model for parallel computing are a so...
There is increasing interest in the use of iterative rather than direct solvers for geotechnical finite element analysis. For large 3D problems iterative solvers offer the only possibility of economical solution on a desktop PC. The major stumbling block with iterative solvers is ensuring fast convergence to a suitably accurate solution. The system of equations is always “preconditioned” to imp...
چکیده : آرای صادره از دادگاه ها علاوه بر شیوه های عادی از طریق فوق العاده نیز قابل اعتراض و رسیدگی مجدد هستند. در مواقعی که رای دادگاه مخل به حقوق ثالث باشد وی می تواند به ان اعتراض کند. قلمرو شمول اعتراض ثالث به تصمیمات قضایی که از آن به رای تعبیر شده محدود می گردد. ولی در مورد قرارها که به اعدادی و نهایی تفکیک می شوند، چون هیچ رویه ثابت و مشخصی در این زمینه در دادگاهها وجود نداشته و همچنین ا...
In this paper we extend the micro-macro decomposition based asymptotic-preserving scheme developed in [3] for the single species Boltzmann equation to the multispecies problems. An asymptoticpreserving scheme for kinetic equation is very efficient in the fluid regime where the Knudsen number is small and the collision term becomes stiff. It allows coarse (independent of Knudsen number) mesh siz...
murder of wife during adultery: if a man sees his wifes adultery with another man, he can kill both of them. and he is not guilty in this murder. this sentence is the opinion of imami jurists and numerous comments on this issue are the main reasons for the sentence. that is the opinion of the sunni jurists too. murder of wife and the stranger man are permitted. but in contrast to these views, ...
abstract nowadays, industries cannot play a crucial role in national and international competitions. the tourism industry is no exception. tourism industry development as the most important economic sector and income generation is one of the key challenges of economic development in the world. therefore, countries were successful that take advantage of the capabilities of tourism sector using ...
