The outbreak of epidemics, the rise of religious radicalization or the motivational influence of fellow students in classrooms are some of the issues that can be described as diffusion processes in heterogeneous groups. Understanding the role that interaction patterns between groups (e.g. homophily or segregation) play in the diffusion of certain traits or behaviours is a major challenge for contemporary societies. Here, we study the impact on diffusion processes of mixing (or, alternatively, segregating) two groups that present different sensitivities or propensities to contagion. We find non

The study on mixed cropping of lentil and wheat was conducted under three levels of irrigation. Wheat at 10, 15, 20, 25, 30, 35, 40, 45 and 50% of the normal seed rates were mixed with full seed rate of lentil to find out a suitable mixing rate of wheat for maximum total yield from unit land. The study was conducted in a split plot design with three replications. Lentil yields obtained with single and two irrigations were identical and higher than with no irrigation. The highest wheat yield was obtained with two irrigations. Total yield was the highest with application of two irrigations. Mixi

The stack-driven flow between two interconnected rooms produced by a single heat source is studied. In particular, the features of the transient flow for different positions and areas of two openings in the shared vertical wall are analysed. An analytical model provides the time evolution of the stratified flows in rooms of any size. The concept of an equivalent layer representing a non-uniform density profile, which is useful in other contexts, is included in the theoretical approach and provides physical insight and aids the mathematical solution of the problem.

This dissertation presents theories of multiwave mixing in two- and three-level media. The first part of the dissertation treats the semiclassical theories in two-level media. Chapter 2 gives the simple semiclassical theory of four-wave mixing when the two pump frequences differ by more than the reciprocal of the population-difference lifetime. This difference washes out the pump spatial holes as well as one of the two reflection gratings. We compare the results to the degenerate treatment of Abrams and Lind and find significant differences in the reflection coefficient spectra. Chapter 3 pres

They can be very useful in quantum computational processes.

This dissertation examines aspects of the interaction of multiple coherent light fields for the two-photon two-level model. In this model the interacting energy levels are not connected by an atomic dipole and a two-photon transition between them is necessary. We employ the density matrix formalism allowing easy comparison between the one- and two-photon two-level models. Significant differences are found due to dynamic Stark shifts and conjugate scattering off the pump-induced two-photon coherence.

AbstractVietnam has approximately 5600 km of coastline and is among the countries most vulnerable to future sea level rise (SLR). In terms of risk of inundation and affected population, Vietnam is one of the countries most at risk from climate change (MONRE 2016; Tamura et al. 2019). According to tide gauge readings, mean sea level increased 2.45 mm/year between 1960 and 2014; satellite data indicates a 3.50 ± 0.7 mm/year rise between 1993 and 2014 (MONRE 2016). As sea levels continue to rise, those living in and near coastal areas face a serious threat.

Multiphoton transitions are of great interest in laser spectroscopy because they permit the study of new physical phenomena and because of their potential applications.

We have recently developed a quantum theory2 to treat such multiwave mixing processes in two-photon media.

We report the first direct evidence that there is collisional mixing between the 2P3/2 and 2P1/2 levels of the copper-vapor laser (CVL), which is excited by a resonant tunable UV laser. When the 2P1/2 level is pumped which generates a yellow laser line (578.2 nm) by a transition to the 2D3/2 level, the 2P3/2 level is also populated, producing a strong green laser line (510.6 nm). On the other hand, when the 2P3/2 level is excited which produces a green laser line by a transition to the 2D5/2 level, the 2P1/2—2D3/2 transition is only weakly stimulated.

This theory accounts for contributions from all velocity subclasses of atoms, not only those which are Doppler shifted into resonance with the laser field (Doppler limit).1 We observe and explain new line shape features based on dissimilar decays.

This work uses on-line monitoring of turbidity to ascertain the temperature impact on the mixing performance of kneading blocks with different geometries. For this purpose, one of the barrel segments of the extruder was modified to incorporate four sampling devices and a slit die containing optical windows. The experiments consisted in reaching steady extrusion and then adding a small amount of tracer. Upon opening each sampling device, material was laterally detoured from the local screw channel and its turbidity were measured by the optical detector. Residence time distribution (RTD) curves

The objective of this effort was to demonstrate in the field the new wettability altering technology developed in the laboratory during Phase 1. Reservoir cores from three gas storage facilities including sandstone and dolomite reservoirs were used to evaluate the two surfactants. The imbibition and core flood tests showed that gas deliverability was improved in surfactant-treated sandstone cores. It was concluded that the aquifer storage facilities are candidates for field testing. Results from Phase I provided the foundation for this Phase II project. The Waverly Storage Facility operated by

Mixing is viewed as being problematic in many internal combustion engines, particularly large bore natural gas engines. In reviewing the literature an attempt is made to distinguish between the influences of mixing and turbulence, although for much of the published research the distinction is not made. Mixing is determined to have a major impact on engine efficiency, overall emissions, flame propagation, and cycle-to-cycle variations. The improvement of engine efficiency and overall emissions is concluded to be primarily due to the extension of the lean limit, a direct consequence of improved

�The purpose of this project was to evaluate the performance of electronic fuel gas admission valves and effects of continuous automatic cylinder balancing of large bore natural gas engines under actual field conditions. These goals have already been met under laboratory conditions at the Colorado State University Engines and Energy Conversion Laboratory in Fort Collins. The specific project objectives were to:1. Extend the feasibility of electronic fuel gas admission valves where gas valve timing and duration are varied to optimize fuel control and charge mixing from the laboratory environmen

Large-bore, natural gas-fueled engines are used for gas compression at over 1700 compression stations across the US, and methane emissions have presented a challenge to their optimization over the years. A significant root of this problem has been linked to the level of air-fuel mixing in the main combustion chamber of these engines as poor mixing results in low combustion efficiency. High-pressure fuel injection is believed to be a significant way to improve air-fuel mixing in natural gas engine combustion chambers. The purpose of this present study is to determine the sensitivity of in-cylin

Beside carbon black, silica powder is the other important filler used to reinforce various colored rubber products. In order to improve the compatibility between silica particles and rubber phase, this work has focused on preparing an NR composite, reinforced by silica generated inside the NR matrix or ‘in situ’. The silica particle was formed by a sol-gel process of tetraethoxysilane (TEOS) dispersed in NR latex. The latex used was concentrated latex having 60% rubber content, and already contained water and ammonia, two ingredients needed for the sol-gel reaction. The conversion of TEOS to s

Термодинамический аппарат с интегрированной динамической системой смешивания и гомогенизации компонентов топлива, в режиме реального времени. Любой вид жидкого углеводородного топлива и особенно топливные композиции на базе жидкого углеводородного топлива, в процессе хранения теряет свою однородность, следствием чего является образование сгустков, преимущественно на донной части ёмкостей, в которых хранится топливо, или топливная смесь. Устранить указанную неоднородность наиболее удобно и эффективно, можно применив процесс гомогенизации, при помощи инновационного устройства динамической гомоге
