Within the local energy independent pseudopotential theory, a convergent supercell calculation of the position of the discrete impurity level produced by the neutral undistorted vacancy in silicon has been performed. Translational symmetry was reintroduced by placing the impurities on a Bravais lattice. The author made calculations with unit cells containing up to 2662 atoms plus vacancy. A deep l
This study identifies teachers’ perceptions of requirements for including collaborations with the surrounding world in their teaching practice, with the aim of providing authentic and entrepreneurial learning environments for students. School management, time and teachers’ personal character traits and disposition were the most frequently stated areas of concern, followed by colleagues, surroundin

We illustrate the scope of time-dependent density-functional theory for strongly correlated (lattice) models out of equilibrium. Using the exact many-body time evolution, we reverse engineer the exact exchange correlation (xc) potential v_(xc) for small Hubbard chains exposed to time-dependent fields. We introduce an adiabatic local density approximation to v_(xc) for the 1D Hubbard model and comp
This thesis research analyzed policies that promote resource mobilization for the development of the Solar Water Heaters and Photovoltaic industries in Mexico. The main inquiry is to identify the role that technological complexity plays in promoting resource mobilization for sustainable transition policies. It is assumed that if the technology is complex, resources are obtained from extra-regional
In the recent three decades, the great development of China’s economy cannot separate from its institutional alterations. Hukou system, an institution with Chinese feature, is a kind of “passport” that admitted in the country. This thesis aims to investigate the Hukou system and its impact on labor migration, and more specifically, how Hangzhou’s Hukou system impacts local economic growth. The res
We study how the orientational correlations of DNA confined to nanochannels depend on the channel diameter D by means of Monte Carlo simulations and a mean-field theory. This theory describes DNA conformations in the experimentally relevant regime where the Flory-de Gennes theory does not apply. We show how local correlations determine the dependence of the end-to-end distance of the DNA molecule

An improved method of calculating the rate of striation thinning for laminar flow in a static mixer has been developed. The shapes of the objects studied are reconstructed using elliptic Fourier descriptors, allowing discrimination between true changes in shape and noise due to discretization errors. The method also allows one to choose the level of complexity in the objects to be reconstructed wh
This paper estimates the influence that rural-to-urban commuting has on rural employment growth, and whether the strength and spatial reach of this effect depend on commuters' levels of education. A main finding is that rural-to-urban commuting has a robust positive impact on rural employment growth in services and retail. There is no significant difference in how far these effects reach into rura
This paper proposes a time-frequency (t-f) image enhancement method for suppressing interference terms in the Wigner-Ville distribution. The proposed technique adapts the direction of the smoothing kernel locally at each t-f point, so that the smoothing kernel remains aligned with the ridges of the auto-terms. This local alignment of the smoothing kernel reduces cross-terms without degrading the e
Background and Objectives: There is a lack of understanding of how older adults' involvement and participation matters in actual design practice. This systematic literature review investigates existing empirical studies involving older users during the design of technologies and explores the nature and consequences of involving older people. Research Design and Methods: Our literature review is in
Eye movements during regular reading, thorough reading, skimming, and spell checking of single pages of text were measured, to investigate how high-level reading tasks elicited by instructions affect reading behavior. Word frequency and word length effects were found. All results were compared to regular reading. Thorough reading involved longer total reading times and more rereading, and resulted
