Interaction effects in topological insulators
… mean-field approaches to study the shortrange interaction effects in topological insulators. We start with the Kane-Mele model on the decorated honeycomb lattice and study the stability of topological insulator phase against different perturbations. We establish an adiabatic connection between …

Interaction effects in quantum interferometers
… of the present thesis is to investigate the effects of interactions in interferometers in the integer quantum Hall regime. The behaviour of electrons in condensed matter systems is mostly determined by the repulsive Coulomb interaction. However, under special circumstances the Coulomb …

Interaction Effects in Nickel Nanowires Arrays
… to the very complicated nature of the interwire interactions, their magnetic behavior is very difficult to be interpreted. The main parameter controlling the response of magnetic nanowires assemblies is the aspect ratio of the nanowires that is defined as the ratio of the length to the wire's …

Fluid-structural interaction effects on vibrations of pipework.
… of this study has been focused on assessing the effects that a fluid has upon the vibratory characteristics of the system concerned. The work elicits both theoretical and experimental investigations into the previously mentioned systems. After considering the physics of the systems involved, and …

Interaction effects on product development networks in China
… The Actors-Resources-Activities (ARA) model of interaction (Hakansson & Snehota 1995) of the business network paradigm is employed to analyse relationship patterns in low, medium and high-tech product development networks, in terms of actor bonds, resource ties and activity links. Although …

Interaction effects and disorder in two-dimensional electron systems
… to study the interplay between electron-electron interactions and short-range disorder at low electron densities, while avoiding the impact of long-range charge inhomogeneities that are usually present in this regime. Indeed, several new observations have been achieved with this approach: Chapter …

Track-Bridge Interaction Effects in Heavy Haul Railway Viaducts
… slab in the case of non-ballasted track. This interaction, commonly referred to as track-bridge interaction results in force transfer between the track and the bridge. With the demand to increase freight haulage on heavy haul railway lines intensifying to meet mineral export demands, there is a …

An Exploration of Interaction Effects in Indonesian Regional Economic Development
The fourth essay measures the economic importance of Indonesian provinces by applying the extraction method within an interregional input-output analysis. The method hypothetically extracts a particular province, and analyzes output differences between the full-region and the hypothetical systems. …

Interaction effects within factor investing in a South African context
… being said, there is limited literature on the interaction effects between these individual factors. This dissertation focuses specifically on quality, value, low volatility and momentum and determines which factors have the largest impact on portfolio return. In addition to testing these single …

The interaction effects of sparse and interlocked connections in SMEs clusters
… theory and network analysis to explore the effects of network structures on SMEs performances in their development. To close this gap, network theory is employed to support this study's hypotheses. Then, this study uses network analysis to generate network snapshots and test proposed …

Soil-structure interaction effects of simple structures supported on rectangular foundations
This thesis deals with the effects of soil-structure interaction, both kinematic and inertial, on the responses of seismically excited rectangular foundations and simple structures supported on such foundations. The ground motion considered is defined stochastically by a local power spectral …

Tokamak burn phase energy optimization with volumetric and wall interaction effects
… ion buildup through the use of a particle-wall interaction model. The D-D, D-T, D-³He reactions are all considered in this model. The energy carried off by the neutrons in the D-D and D-T reactions is lost from the plasma. Impurities enter the plasma as a result of wall interactions with …

Charge Interaction Effects in Epoxy with Cation Exchanged Montmorillonite Clay and Carbon Nanotubes.
The influence of charge heterogeneity in nanoparticles such as montmorillonite layered silicates (MLS) and hybrid systems of MLS + carbon nanotubes was investigated in cured and uncured epoxy. Epoxy nanocomposites made with cation-exchanged montmorillonite clay were found to form agglomerates near …

Extending the Information Partition Function: Modeling Interaction Effects in Highly Multivariate, Discrete Data
Because of the huge amounts of data made available by the technology boom in the late twentieth century, new methods are required to turn data into usable information. Much of this data is categorical in nature, which makes estimation difficult in highly multivariate settings. In this thesis we …

Statistical analysis of the vertical human walking forces and human structural interaction effects
… does not disclose or encourage human structure interaction effects, even though a significant body of research demonstrates the benefits of its inclusion. Current estimations of structural responses do not align with the physical measurements of structures. The resultant acceleration estimations …
