Subordinacy and spectral analysis of Schrödinger operators
… and some related aspects of scattering theory. After an introductory discussion on the aims of the thesis and its relation to existing work, the background mathematical material required for subsequent developments is presented in Chapter II. The theory of subordinacy, which relates the …

Corrections to the Debye-Hückel Theory
<p>The cluster expansion theory of Mayer is rearranged to obtain expressions for the potential of average force and the internal potential energy of the electron gas through order n<sup>3/2</sup> in the density n. The order n result for the potential of average force is applied to ionic solutions, …

A Higher-Order Method Implemented in an Unstructured Panel Code to Model Linearized Supersonic Flows
… for supersonic conical flows and 2D shock-expansion theory, and the PANAIR and MARCAP supersonic panel codes. Results correlate well with the analytical solutions, and show strong agreement with the other codes.</p>

Discrete generalized multigroup theory and applications
… new discrete generalized multigroup energy expansion theory for the linear Boltzmann transport equation. Discrete orthogonal polynomials are used, in conjunction with the traditional multigroup representation, to expand the energy dependence of the angular flux into a set of flux moments. …

The role of social media in HIV/AIDS communication: The relationship between perceived need and design utilities
… channel. Following the media richness theory (MRT) and channel expansion theory (CET), a model is proposed that suggests that need utilities drive social media utility. It is furthermore suggested that social media utility is positively associated with the design appropriateness of …

Pore-water pressure accumulation under dynamic loadings
… on a limit pressure calculated using cavity expansion theory and a semi closed-form solution that is scaled to existing calibration chamber data using a chamber shape factor. This enables estimation of ψ directly from CPT results, which makes it practical and theoretically sound. This …

High-performance computing for smart grid analysis and optimization
… (NR). A cumulant-based method and Gram-Charlier expansion theory are used to efficiently obtain the statistics of system states. We also develop a more accurate linear mapping method to compute the unknown cumulants. ClusRed can speed up the computation by up to 4.57X and can improve accuracy by …

Studio multiscala degli stati elettronici e di spin indotti da difetti di punto in semiconduttori a banda larga e prospettive per le tecnologie quantistiche
… mediante la teoria Cluster Correlation Expansion. Troviamo un decadimento della coerenza non esponenziale, che è una caratteristica tipica dei qubit a stato solido. Estendiamo l'analisi delineata alle vacanze di silicio in diverse nanoparticelle 3C-SiC per applicazioni in Quantum …
