1999   Cysteamine coated Ag and Au nanorods for improved surface enhanced Raman scattering from dinitrotoluene and trinitrotoluene Cysteamine coated Ag and Au nanorods for improved surface enhanced Raman scattering from dinitrotoluene and trinitrotoluene O. J. Glembocki    0 Surface-enhanced Raman scattering (SERS) from trinitrotoluene and other nitro-based explosives is important for the development of a reliable detection scheme exhibiting low false-positive rates. However, the interaction of these compounds with Ag and Au causes the molecules to orient in ways such that the primary vibrations of the nitro groups, the main identifying Raman marker of these compounds, are inhibited in addition to causing a reduction in the SERS response. It has recently been shown ... 查看全文

2001   NORMALIZATION IN ECONOMETRICS NORMALIZATION IN ECONOMETRICS James D. Hamilton, Daniel F. Waggoner    0 □ The issue of normalization arises whenever two different values for a vector of unknown parameters imply the identical economic model. A normalization implies not just a rule for selecting which among equivalent points to call the maximum likelihood estimate (MLE), but also governs the topography of the set of points that go into a small-sample confidence interval associated with that MLE. A poor normalization can lead to multimodal distributions, disjoint confidence intervals, and very mislea 查看全文

2002   nfn2dlp: A Normal Form. Nested Programs Compiler ⋆ nfn2dlp: A Normal Form. Nested Programs Compiler ⋆ Annamaria Bria, Wolfgang Faber, Nicola Leone    0 Abstract. Normal Form. Nested (NFN) programs have recently been introduced in order to allow for enriching the syntax of disjunctive logic programs under the answer sets semantics. In particular, heads of rules can be disjunctions of conjunctions, while bodies can be conjunctions of disjunctions. Different to many other proposals of this kind, NFN programs may contain variables, and a notion of safety has been defined for guaranteeing domain independence. Moreover, previous results show that the... 查看全文

2007   Inertial effect on the natural convection flow within a fluid-saturated porous medium Inertial effect on the natural convection flow within a fluid-saturated porous medium    1993 The general momentum equation for fluid flow within a porous medium is supposedly valid for any fluid-porous medium configuration. One of the main concerns of using the general equations refers to the inclusion of both inertia terms, namely, the convective inertia term and the Forchheimer term. In this study, we go beyond the important discussion about the correctness of including both terms in the general momentum equations by focusing upon the effect of the convective inertia term on the heat ... 查看全文
