Mesoscopic simulations of electrohydrodynamic phenomena
Mesoskopische Simulationsmethoden wie Dissipative Particle Dynamics erlauben die Untersuchung eines Soft-Matter-Systems auf langen Zeit- und großen Längenskalen. Verschiedene elektrokinetische Effekte wie der elektroosmotische Fluss, Polyelektrolyt-Dynamik in freier Salzlösung und Elektrophorese …

Mesoscopic lattice Boltzmann nemato-dynamics.
In this thesis we have developed an anisotropic lattice Boltzmann (LB) model that recovers the incompressible isentropic Ericksen-Leslie-Parodi (ELP) equations of continuum nemato-dynamics in two dimensions with the director confined to the plane. Suitable validations of the developed model against …

Quantum behavior in mesoscopic systems
… parts; in the first one I present the study of mesoscopic quantum systems whereas in the second one I address the problem of the definition of Markov regime for quantum system dynamics. The first work presented is the study of vortex patterns in (quasi) two dimensional rotating Bose Einstein …

Mesoscopic modeling of protein conformational changes
… theoretically with the help of coarsegrained mesoscopic models of protein structure. The models explicitly incorporate the effects of the polarity of the peptide backbone and of the specificity of hydrophobic interactions. These two features are found essential to give a realistic phase …

Nonequilibrium properties of mesoscopic superconducting rings
… we study certain nonequilibrium properties of mesoscopic superconducting rings, i.e., rings of finite circumference. Two classes of nonequilibrium behavior will be considered: (i) the system is prepared in a nonequilibrium state and subsequently allowed to relax toward equilibrium, and (ii) the …

Mesoscopic Fuel Consumption and Emission Modeling
… modeling vehicle fuel consumption and emissions mesoscopically. This framework is utilized to develop the VT-Meso model using a number of data sources. The model estimates average light-duty vehicle fuel consumption and emission rates on a link-by-link basis using up to three independent …

Techniques and Applications of Mesoscopic Fluorescence Imaging
… depth in bioscience and medical research, mesoscopic imaging exchanges resolution for penetration depth, which offers hundreds of micrometer resolution and up to several millimeter penetration depth. By introducing fluorescence dyes or with intrinsic fluorescence, much higher contrast of …

Thermoelectric properties of mesoscopic systems in GaAs
… describes the thermoelectric properties of mesoscopic structures in modulation doped GaAs/ Al0.33Ga0.67As heterostructures. In particular, we study the thermopower of two-dimensional mesoscopic systems (2DMSs) and antidot lattices defined in them. Quantum oscillations in the thermopower (TP) …

Magnetic force microscopy studies of mesoscopic superconducting structures
… for investigating vortex and fluxoid sates in mesoscopic superconducting (SC) structures. The technique relies on the magneto-mechanical coupling of a MFM cantilever to the motion of fluxons. The novelty of the technique is that a magnetic particle attached to the cantilever is used not only to …

Commercialization potential of dye-sensitized mesoscopic solar cells
The price of oil has continued to rise, from a high of US$100 per barrel at the beginning 2008 to a new record of above US$140 in the recent weeks (of July). Coupled with increasing insidious greenhouse gas emissions, the need to harness abundant and renewable energy sources is never more urgent …

Mesoscopic wave phenomena in electronic and optical ring structures
Gegenstand dieser Arbeit sind Wellenphänomene in mesoskopischen Ringstrukturen. In Teil I der Arbeit befassen wir uns mit spinabhängigem Transport von Elektronen in effektiv eindimensionalen Ringen in Gegenwart inhomogener Magnetfelder. Wir benutzen die exakten Lösungen der Schrödinger-Gleichung im …

Mesoscopic dynamics of pitch processing in human auditory cortex.
Pitch is a perceptual correlate of sound periodicity elicited by vibrating bodies; it plays a crucial role in music and speech. Although perceptual phenomenology of pitch has been studied for centuries, a detailed understanding of its underlying neural mechanisms is still lacking. Early theories …

Mesoscopic noise probe of an inhomogeneous colossal magnetoresistance phase
Epitaxial single-crystal films of La2; 3Ca1; 3Mn03 exhibit large discrete equilibrium resistance fluctuations in the region of phase space where colossal magnetoresistance effects are strongest. The fluctuators' dependence on magnetic field indicates that the resistance steps represent small …

Mesomatters - design, manufacture and interact with architected mesoscopic materials
Between traditional industrial design, which operates at the macro scale (cm to m), and material engineering, which operates at the micro/nano scale ([mu]m to nm), is the emerging design space of the mesoscale. While the definition of mesoscale varies across disciplines, mesoscale materials are …

Mesoscopic Distinct Element Method for Multiscale Modeling of Carbon Nanotubes
… modeling and the lack of mesoscale models, mesoscopic simulation methods for CNT systems are missing. My work focuses on deriving ultra-coarse-grained models based on mesoscopic dintinct element method (mDEM). Our mDEM model is informed by atomistic data obtained with molecular dynamics (MD) …
