Numerical simulation of optical wave propagation through random media
… simulation. For instantaneous realization of a random medium, a simplified version of the random-motion model [77] is used, and for wave-propagation calculation the wave-kinetic numerical method and/or the angular-spectral representation of the Huygens-Fresnel diffraction formula are used. For …

On Existence and Convergence of SLE in Multiply Connected Domains
… in terms of the driving function, which is a random motion on the boundary of the domain. As the inner circular hole of a domain where a bilateral SLE curve grows shrinks to a point, its driving function goes to a limit, which is a natural driving function of the corresponding radial SLE, up …

VPS1 on Dynamics of Endocytic Components and Endocytic Scission
… Abp1-GFP in the GED mutant exhibited not only random motion as is the case in vps1Δ, but also a slow dissociation from the patch. Consistent with Abp1-GFP disassembly, I found that the disassembly rate of the endocytic adaptor protein Sla1 was significantly decreased, and conclude that the …

Integrating novel rheological tools with microscopy to characterize viscoelastic properties of complex materials
… (PTM) is a technique that uses Brownian motion of colloidal probe particles to characterize the mechanical properties of materials at micron length scales. However, this method cannot be used in higher modulus materials (G*>10^1 Pa) because the particles experience restricted Brownian …

Novel Invariant Features of the US Stock Market
… Specifically, we model price fluctuations as a random motion that cannot be predicted nor replicated. Scientific measurements rely on invariance, the reproducibility of conclusions in nominally identical experiments. Only they can be used to characterize the underlying process. This thesis will …

Design, Fabrication, and Characterization of an Array of Graphene Based Variable Capacitors
… structure, and these ripples are in constant random motion even room temperatures. Occasionally, the ripples undergo spontaneous buckling (change of curvature from concave to convex and vice versa) and the potential energy associated with this is a double well potential. This movement of …

Vibration in vehicles: its effect on comfort
… contours were obtained using sinusoidal and random motion. An additional study to investigate the sensitivity of subjects to lateral seat motion in the same frequency range was also conducted. The results of these studies together with information obtained from two experiments which …

Mathematical modelling of growth factor induced cell migration in 3D engineered matrices
… migration. Cell-substrate adhesion and partial random motion are included. Further, the Green function and Duhamel principle are used to solve the diffusion equation to describe the presence of a growth factor and represent chemo-mechanically induced deterministic collective cell migration on …

Cellular tracking and mitosis detection in dense in-vitro cellular data
… such as changes in cell morphology over time, random motion, cell division, cell interaction and low signal to noise ratio. To answer these challenges in a robust manner, several approaches have been advanced where the key task was the cellular association. In this regard, the major directions …

A Robust Algorithm for Identification of Motion Artifacts in Photoplethysmography Signals
… the sensor measurements using PPG. Presence of motion artifacts in the signal decreases the accuracy of estimating the parameters and therefore reduces the reliabilty of these sensor devices. Motion artifacts can be both periodic or aperiodic. Existing state-of-the-art methods for motion …

Mobility Pattern Aware Routing in Mobile Ad Hoc Networks
A mobile ad hoc network is a collection of wireless nodes, all of which may be mobile, that dynamically create a wireless network amongst them without using any infrastructure. Ad hoc wireless networks come into being solely by peer-to-peer interactions among their constituent mobile nodes, and it …

Collaborative control strategies for robotic manipulation
… has been applied to a manipulator synchronised motion task. <br/><br/>The area of MPC obstacle avoidance was next investigated. Working in shared environments, robots must have the capability to avoid other entities and obstructions, so this approach improves the usefulness of a robot equipped …

Particle tracking for understanding the properties and dynamics of bacterial biofilms
… can also be analyzed to better understand motion patterns of motile probes or to assess for diffusive behavior. In this work, particle tracking was used in different contexts to assess various biofilm systems. The overall goal was to gain an understanding of the structure, physical …
