Accelerating and Converging Stochastic Quantum Chemistry
In the last decade, stochastic versions of quantum chemistry methods such as coupled cluster Monte Carlo (CCMC) or full configuration interaction quantum Monte Carlo (FCIQMC) have made highly accurate energy calculations possible that are not accessible to the corresponding deterministic methods …

Converging biochemical pathways in psychiatric disorders
According to the World Health Organization, neuropsychiatric diseases account for approximately one third of years lost to disability. Yet, despite this huge disease burden, there is a lack of new treatments under development: approved treatments all essentially target the same target(s), if the …

Boundary layer growth in a converging nozzle
… for en incompressible fluid flow through a converging nozzle is presented. Calculations are based on a nozzle whose walls have a constant radius of curvature and a 2:1 entrance area to throat area ratio. An equation for the free stream velocity es a function of the arc length of the nozzle …

Integration Over Converging Arcs in the Plane
Most standard theorems on convergence of integrals consider the integrals of a family of functions over a fixed domain of integration; however, situations occur in which one needs to approximate a curve over which a function is to be integrated by means of a sequence of piecewise smooth curves. …

Converging behaviorist and constructivist theories in classroom settings
… of this study is to assess the effectiveness of converging behaviorist and constructvist theories into classroom management and instructional practices. Three groups of students were randomly selected, and their progress was monitored over the course of one month. Results revealed that the group …

Telematics industry dynamics and strategies for converging technologies
… the telematics architecture and the technologies converging in the telematics system I suggest a mixed strategy with respect to standards. This strategy favors the growth of this industry. Based on this strategy there are developed some scenarios of how the telematics value network will look like …

Dense gas effects in a converging-diverging nozzle
… for the solution of steady inviscid flows in a converging-diverging nozzle are presented for a general fluid. The main emphasis is placed on Bethe-Zel'dovich-Thompson fluids, i.e., those having specific heats so large that the fundamental derivative of gasdynamic is negative over a finite range …

Manufacturing and Experience: a Story of Converging Paths
CONVERGENCE OF PATHS Within the vast urban fabrics live many threads of paths. These paths weave in, out, diagonal, above and underground forming city blocks that we well know. Events happen when these paths interact. They either weave into each other or separate into many. Sometimes a force or …

Dynamics of Rigid Fibers in a Planar Converging Channel
The influence of turbulence on the orientation state of a dilute suspension of stiff fibers at high Reynolds number in a planar contraction is investigated. High speed imaging and LDV techniques are used to quantify fiber orientation distribution and turbulent characteristics. A nearly homogenous, …

Characterization of microparticle velocities in converging-diverging nozzle systems
… utilizes an experimental system incorporating a converging-diverging nozzle to accelerate well characterized particles to high speeds via aerodynamic drag force on the particle and measures the resulting velocities. Velocity measurements in the range of 0.3 - 1 km s-1 were taken for singularly …

Saudi students and IEP teachers: converging and diverging perspectives
This research investigates the perspectives of teachers and Saudi students in an Intensive English Program (IEP) on the necessary skills for international students’ success in American university classes, the IEP’s effectiveness in developing those skills, and on the role of high-stakes …

Toward culture : converging on the civic moment in architecture
This thesis is an investigation into physical constituents of civic architecture including some speculation on how civic architecture pertains to cultural awareness. The process of investigation is carried out through architectural exploration and definition of a site in the city of Boston. The …

Converging Pathways: Neuroimmunology of Tauopathy and Mild Traumatic Brain Injury
Age-related neurodegenerative diseases impact over 60 million people worldwide with the number steadily increasing each year as the global population ages. Despite years of research and many clinical trials, no therapeutic has proven efficacious at addressing disease progression. The vast …

The structure and stability of expanding and converging near-stoichiometric flames
The stability of expanding and converging premixed flames is investigated theoretically. These configurations are inherently unsteady and represent simple examples of positively (expanding) and negatively (converging) stretched flames. A new model is employed in this study that incorporates both …

IMPROVING RESOLUTION IN WRIST SPECT WITH CONVERGING COLLIMATORS AND CT ANATOMICAL PRIORS
Wrist injuries account for over 750 000 visits to the hospital each year. Better imaging techniques are required to properly diagnose these injuries. Planar nuclear medicine offers a high sensitivity for fracture detection, but low specificity. Improving resolution could lead to better specificity. …

Framing Hudson Square: A Stair Encloses a Converging Grid in the City
This thesis explores an alternate typology for a residential high rise in the Hudson Square neighborhood in Manhattan. The units that make up the building are organized with stairs and corridors placed along the interior perimeter of the unit which both bound the central floor space and expose it, …

Converging evidence on the autonomy and abstractness of the representation of lexical stress
The experiments reported in the thesis investigate the nature of word stress and its lexical representation. Focusing on Italian, I considered two research questions: How is lexical stress represented? How does this representation intervene in perceiving or producing a word? Italian is a …
