Two-color photon echo peak shift spectroscopy was used to study electronic coupling in a phthalocyanine homodimer. Two optical parametric amplifiers were used to produce pulses to excite the split lower states of LuPc2-. The existence of a two-color peak shift indicates the existence of correlation between these two dipole-allowed states. The nature of this correlation is discussed based on the...
Analytical solutions are developed for the response of saturated porous media under twodimensional plane strain condition. Depending on the nature of loading vis-à-vis the characteristics of the media, different formulations (fully dynamic, partially dynamic, quasi-static) are possible. The solutions for these formulations are developed in terms of non-dimensional parameters. The regions of val...
This paper outlines a general approach to non-parametric regression. It provides a discussion of the methdology when applied to the standard normal error univariate nonparametric problem , then outlines how it can be extended to additive models and nonparametric regressions with a variety of diierent error processes. The estimation is provided by Markov chain Monte Carlo schemes that are fast, ...
In this paper, we analyse the formation of goal of motion interpretation in English and Italian. We argue that contrary to what has been argued, both languages do form goal of motion interpretations although in a manner constrained by the principles of event structure composition. Parametric variation among the two languages will be driven by: (i) the nature of lexical prepositions available; (...
In this paper, an Economic Order quantity (E.O.Q) model with unit production cost, time depended holding cost, with-out shortages is formulated and solved. In most real world situation, the objective and constraint function of the decision makers are uncertainty in nature so the coefficients, indices the objective function and constraint goals are imposed here in fuzzy environment The problem i...
We propose a model of price formation in Double Auction markets which employs the strong simplifying assumption that agents neglect strategic feedback effects and regard themselves as playing a Game against Nature. Agents otherwise are strict expected utihty maximizers employing Bayesian updating procedures. We prove the optimality of simple (‘aggressive reservation price’) strategies in our ge...
راکتورهای همجوشی، ماشین هایی برای استخراج انرژی هسته ای می باشند. در این راکتورها هسته های عناصر سبک در طی یک واکنش همجوشی هسته ای به هست? سنگین تر تبدیل می شوند که این واکنش با تولید انرژی همراه است. محاسبات نشان می دهند که به منظور داشتن راکتوری بهینه، سوخت همجوشی باید دارای دمایی از مرتب? 10میلیون درج? سانتی گراد و چگالی ای از مرتب? 23^10 ذره بر مترمکعب باشد. بنابراین، مسئل? گرم کردن ومحصورس...
Parametric engineering models of the gas dynamic mirror (GDM) fusion propulsion systems[1, 2, 3, 4] have produced potentially feasible systems. However, these systems are extremely large and massive due to neutron or bremsstrahlung radiation losses for traditional and advanced fusion fuels, respectively. In order to explore designs beyond the simple uniform GDM represented by the parametric mod...
This paper constructs a composite leading index for business cycle prediction based on vine copulas that capture the complex pattern of dependence among individual predictors. This approach is optimal in the sense that the resulting index possesses the highest discriminatory power as measured by the receiver operating characteristic (ROC) curve. The model specification is semi-parametric in nat...
