Experimentally Derived Sticking Efficiencies of Microparticles using Atomic Force Microscopy: Toward a Better Understanding of Particle Transport
… collector surface. Sticking efficiencies were derived from intersurface potential energies that were determined from integrated force-distance data measured by Atomic Force Microscopy (AFM). Force data were measured in buffered aqueous solutions of varying pH and ionic strength to determine the …

Improvement of structural dynamic models via system identification
… These methods range from completely analytically derived models, completely experimentally derived models, to a combination of the two. These model generation procedures are called System Identification. Today a popular method is to create an analytical model as accurately as possible and then …

Computational and experimental investigations of biologically interesting molecules
… methods, and compared these results to relevant, experimentally derived data.

A field evaluation of the formative conditions, wavelengths and heights of alternate bars in alluvial channels
… field study quantitatively assesses: (1) six experimentally derived formulas that predict the conditions for alternate bar formation and equilibrium bar dimensions, and (2) a physically-based nonlinear mathematical theory of alternate bar formation under unsteady natural flow conditions within …

Integrating In-Silico Models with In-Vitro Data to Generate Novel Insights into Biological Systems
… data is often underutilised. Incorporation of experimentally derived data sets into the mathematical framework of in-silico modelling results in reliable, well parameterised systems capable of replicating dynamical properties of the biological systems. Work in this thesis includes the …

Action Potential Simulation of the Hirudo Medicinalis's Retzius Cell in MATLAB
<p>Modification of Hodgkin and Huxley’s experimentally derived set of nonlinear differential equations was implemented to accurately simulate the action potential of the <em>Hirudo Medicinalis’s</em> Retzius cell in <em>MATLAB</em> under analogous conditions to those found in the Retzius cell …

Application of the peat archive as tool in environmental chemistry
… cores are generally in agreement with trends derived from a sediment core sampled close by, but rates are higher to the sediment for PAHs but similar for PCBs. Indication for mobility of PAHs was minor but has been observed in peat for PCBs and PFAS. To predict the environmental behavior of …

Byzantine Music Intervals: An Experimental Signal Processing Approach
… by a well recognized chanter in order to derive experimentally the mean frequencies of the first five tones (D – A) of the diatonic scale of Byzantine Music. Then we compared the experimentally derived frequencies with frequencies proposed by two theoretical scales, both representative of …

Deep Learning for Segmentation Of 3D Cryo-EM Images
… test cases. The architecture was also applied to experimentally-derived cryo- EM density regions of 571 protein chains. . The average F1 score for helix detection is 0.747 and 0.674 for β-sheets in a test involving seven cryo-EM density regions. Additionally, we extend an arc-length association …

Increasing adder efficiency by exploiting input statistics
… find that in certain circumstances the use of experimentally derived activity maps rather than ones based on simple assumptions can increase adder performance by as much as 30%.

Quantitative analysis of adenoviral vector modification of a cytokine-mediated cell death decision
… changes in TNF-mediated apoptosis. We experimentally derived a mathematical equation describing the saturation of anti-apoptotic Akt effector signaling in the presence of high levels of Adv infection, which could predict TNF-induced apoptosis in HT-29 cells.

Optimization of ligament parameters on a subject-specific computational human knee model in a dynamic knee simulator using design of experiments
… The resulting parameter values are 80% of the experimentally derived zero load length values, 99.71% of the published ligament stiffness values, and 100% of the published epsilon sub l. These values are reasonable, and are validated by the stiffness values from the optimization closely matching …

Supermanoeuvrability in a biomimetic morphing-wing aircraft
… models; and validated with respect to experimentally-derived flight dynamics of a Pioneer RQ-2 UAV. These models are used to explore the capability of this system for a wide range of biological and other supermanoeuvres: multi-axis quasistatic nose-pointing-and-shooting (NPAS) / direct …

Metabolic Changes in Astrocytes Following Traumatic Brain Injury
… model. Physiologically relevant constraints from experimentally derived astrocyte metabolite uptake rates bounded upper and lower limits of astrocyte metabolism. Hypoxia and acidosis were simulated by restraining extracellular oxygen uptake rate and the intracellular pH buffering capacity of …

Multivariate Analysis of Factors Regulating the Formation of Synthetic Allophane and Imogolite Nanoparticles
… models also were able to consistently predict experimentally derived results from other studies. These results demonstrated the ability to use this approach to understand complex geochemical systems with competing influences, as well as provided insight into the formation of imogolite and …

Lumped approach for sorption of organic contaminant mixtures to simulated aquifer sorbents
… lumped approach was evaluated on the basis of experimentally derived lumping criteria (i.e., Freundlich sorption parameters). Also, the use of the ideal adsorbed solution theory (IAST) with the determined pseudocompounds for predicting the sorption of the 12 NOCs within complex mixtures to …

In-line treatment of metal contaminated storm water by charred microporous polymers
… not Ni(2+). A scenario was conducted based on experimentally derived Cu(2+) adsorption results to estimate the filter service time for the adsorbers tested when placed with in existing in-line storm water treatment system and exposed to Cu(2+) contaminated storm water. Storm water flows from 1, …

Detailed Kinetic Modelling of the Oxidation and Combustion of Large Hydrocarbons Using an Automatic Generation of Mechanisms
… shows good agreement with experimental results. Experimentally derived and numerically predicted ignition delays of n-heptane/air and n-decane/air mixtures in high-pressure shock tubes in a wide range of temperatures, pressures and equivalence ratios agree very well. Concentration profiles of the …
