Abstract:
Development of methods for controlling the change in the functional cover and the energy composition of the surface of detonation synthesis diamond nanopowders is necessary to create stable suspensions and materials from them. The aim of this work is to study changes in the electrokinetic and electrophysical characteristics of the powder as a result of the modification of detonation synthesis diamond nanopowders using a liquid-phase thermochemical treatment. Diamond nanopowders of grades ASUD-75 - ASUD-99 with different sp2-hybridization carbon content, manufactured at the V.I. Bakul National Academy of Sciences of Ukraine from the product of detonation synthesis of diamond from the company "ALIT" (Zhytomyr) investigated. Diamond nanopowders of ASUD-90 grade after their modification by means of liquid-phase thermochemical treatment using: a melt of alkalis, a mixture of nitric and sulfuric acids, a mixture of chromic and sulfuric acids were investigated by electrophoresis using a device "Dzeta-potential-analizer" company "Mikromeritiks". Electrokinetic characteristics of diamond nanopowders: the magnitude and sign of the electrokinetic potential, electrophoretic mobility are determined. The methods were used to study the physicochemical characteristics of nanopowders: electrical resistivity, carbon content of sp2-hybridization, mass fraction of impurities in the form of an incombustible residue, and specific surface area. In this work, it was established by electrophoresis that the value of the electrokinetic potential and electrophoretic mobility of the powder decrease by 2-10 times with a decrease in the mass fraction of sp2-hybridization carbon from 23.6 to 0 wt%. Using the ASUD-90 nanopowder as an example, it is shown that the modification of the nanopowder by the liquid-phase method using thermochemical treatment with mixtures of oxidants leads to a decrease in the values ​​of electrophoretic mobility by 1.1-7.5 times and electrokinetic potential by 1.1-7.3 times. It was found by dielectric measurement that the tangent of the dielectric loss angle of diamond nanopowders of grades ASUD-90 - ASUD-99 is in the range 0.3046 - 0.3146. Modification of the ASUD-90 grade nanopowder using a liquid-phase thermochemical treatment leads to a change in the interval of the dielectric loss tangent, namely 0.2450-0.3249. According to the degree of increase in the ratio of the dielectric loss tangent from 0% humidity to 100% humidity, the methods for modifying nanopowders can be arranged as follows: modifying using a melt of alkalis (ASUD-90-1 sample, S = 12.8%) <mixture of chromic and sulfuric acids (sample ASUD-90-3, S = 13.8%) <mixture of nitric and sulfuric acids (sample ASUD-90-2, S = 20.8 %).

Abstract:
Surface chemistry has a large influence in many industries. In the life sciences, surface area is gaining importance in the characterization of materials during their development, formulation and manufacturing. The chemical activity, adsorption, dissolution, and bioavailability of a drug may depend on the surface of the molecule. In order to meet manufacturing challenges and develop new and better performing products with improved qualities, knowledge of surface tension is of utmost importance. An attempt has been made in this paper to review the application of interfacial tension in the key domains of pharmaceutical applications.

Abstract:
The surfaces of animals, plants and abiotic structures are not only important for organismal survival, but they have also inspired countless biomimetic and industrial applications. Additionally, the surfaces of animals and plants exhibit an unprecedented level of diversity, and animals often move on the surface of plants. Replicating these surfaces offers a number of advantages, such as preserving a surface that is likely to degrade over time, controlling for non-structural aspects of surfaces, such as compliance and chemistry, and being able to produce large areas of a small surface. In this paper, we compare three replication techniques among a number of species of plants, a technical surface and a rock. We then use two model parameters (cross-covariance function ratio and relative topography difference) to develop a unique method for quantitatively evaluating the quality of the replication. Finally, we outline future directions that can employ highly accurate surface replications, including ecological and evolutionary studies, biomechanical experiments, industrial applications and improving haptic properties of bioinspired surfaces. The recent advances associated with surface replication and imaging technology have formed a foundation on which to incorporate surface information into biological sciences and to improve industrial and biomimetic applications. This article is part of the theme issue ‘Bioinspired materials and surfaces for green science and technology’.

Computerized symbolic computation reflects the rapid expansion of computer sciences in various fields of science and engineering, while the studies on the liquid surfaces for rivers, oceans, aviation kerosene, liquid propellant for rockets, etc., are of current interest. In the presence of surface tension or sea ice, and with symbolic computation, the Hărăgus-Courcelle-Il’ichev model for surface liquid waves is hereby investigated. Several similarity reductions are presented, some of which are explicitly written out as exact analytic solutions having their rational expressions with respect to the dimensionless spatial variables of the model.

Abstract:
L'enjeu de ces travaux consiste en la représentation de motifs structuraux réguliers des protéines : les feuillets β. Les représentations classiques de la modélisation moléculaire n'étant pas satisfaisantes, étant donne qu'elles ne représentent pas les feuillets β dans leur ensemble, nous proposons nos modèles représentant ces structures sous forme de surfaces. Nous utilisons le logiciel open source ≪ BALLView ≫ pour créer nos propres modèles de feuillets β. La première approche utilise la description des feuillets β présente dans les fichiers issus de la ≪ Protein Data Bank ≫, la banque de données mondiale de structures protéiques, pour calculer une interpolation bidimensionnelle basée sur les splines de Catmull-Rom. La seconde approche utilise des carreaux de Bézier, construits a partir des résultats issus d'un algorithme d'attribution des structures secondaires des protéines, dont les feuillets β font partie. Ces approches sont les premières à représenter les feuillets β dans leur ensemble. Les modèles classiques ne représentent que les brins β. Pour visualiser leur orientation nous plaquons cette information par le biais de textures. Cela nous amène à considérer nos surfaces comme de nouveaux medias sur lesquels nous pouvons dépeindre des données supplémentaires par l'intermédiaire de méthodes de coloration (≪ Hydrophobic Cluster Analysis ≫, ≪ Molecular Hydrophobicity Potential ≫…). Nos modèles sont utilisables sur l'ensemble des fichiers au format PDB, en statique, mais également sur des fichiers de simulation de dynamique moléculaire. Nous pouvons alors constater l'évolution des feuillets β, leurs déformations, l'apparition de trous, d'invaginations ou de déchirures. Ces constatations nous amènent à baptiser nos modèles SheHeRASADe pour ≪ Sheets Helper for RepresentAtion of SurfAce Descriptors ≫. Nous nous intéressons, entre autres, à l'application de ces modèles sur les divers repliements protéiques des feuillets β repertoriés dans la classification CATH, ainsi qu'aux fibres amyloides, impliquées dans de nombreuses pathologies
The aim of this work consists in the representation of common structural motifs of proteins: the β sheets. The classical visualization modes are not satisfying, considering that they don't represent the whole β sheets. We propose innovative models materializing those structures using surfaces. We use the open source software "BALLView" to create our own β sheet models. The first one uses the β sheets description stored in files from the Protein Data Bank, the worldwide data bank of proteic structures, to compute a bidimensionnal interpolated surface based on Catmull-Rom splines. The second one uses Bezier patches defined from β sheets produced by a secondary structure prediction algorithm. Those models are the first ones to fully represent β sheets. Previous methods only represent β strands. In order to visualize their orientation, we map these important data to our surfaces by using textures. It leads us to consider our surfaces as a new medium on which we can depict additional information using coloring methods (Hydrophobic Cluster Analysis, Molecular Hydrophobicity Potential. . . ). Our models are available for any PDB formatted file, in both static and dynamic ways, using molecular dynamics simulations. We can observe the evolution of β sheets, deformations, holes appearances, invaginations or splits. Those observations lead us to call our models SheHeRASADe for "Sheets Helper for RepresentAtion of SurfAce Descriptors". We apply those models to the different proteic folds of β sheets listed in the CATH classification, and on amyloid fibrils involved in many diseases

Abstract:
Poly(vinyl alcohol) (PVA) is a polymer used in numerous applications, principally those in which its high water solubility is a desirable asset. However there are also areas where PVA is limited by its inherent solubility (for example some specific environments in the biomedical field). This work has sought to overcome such limits by manipulating the surface of PVA in order to propose various means by which the surface solvent resistance might be increased while maintaining the bulk properties of the polymer. Both chemical and physical modifications have been tried and in each case progress has been made towards insolubilizing a single surface of the polymer when in film form. Grafting various species onto the surface of PVA was successfully performed. It is believed that such species bonded to the PVA via attachment to the hydroxyl groups (though this has not been proven conclusively). The data contained herein has led to the conclusion that the primary factor in reducing solubility this way is the removal of the hydroxyl groups, and not the attachment of specifically highly hydrophobic molecules. Introducing permanent cross-links into the surface region has been attempted via various routes. The data recorded shows promise however the system is far from optimised. The biggest challenge remaining is to optimise the depth of material cross-linked. Some steps have been made towards understanding and controlling this parameter though there is much scope for further investigation. The methods used have built on those used for bulk cross-linking and as such are new for the case of surface specific treatment. An interesting phenomenon in some semi-crystalline polymers reported in recent years is that of surface specific crystallization. This effect has been successfully induced and observed in PVA to produce what is believed to be a highly crystalline surface layer, and crystalline regions of PVA are generally accepted to be more water resistant than amorphous ones. In summary, in this work several surface-specific treatments for PVA have been trialled, providing options for post-film forming modification to reduce the surface water sensitivity whilst retaining the bulk properties of the polymer.

Abstract:
Implied volatility surfaces are central tools used for pricing options. This thesis treats the topic of their construction. The main purpose is to uncover the most appropriate methodology for constructing implied volatility surfaces from discrete data and evaluate how well it performs. First some methods and techniques in use for such surface constructing are presented. Then the most attractive approach, chosen to contain 4 interesting models is studied. The models’ performances are tested on two price grids from the EURO STOXX 50 and Nikkei 225 indices. The found implied volatility surfaces give good and decent fits to the data, respectively. The surfaces are evaluated in terms of presence of static arbitrage and are found to have it, although mostly for strike price and time to maturity combinations which are somewhat abnormal and rarely traded. Arbitrage is found to be more prevalent in surfaces when the input data is of lower quality. The volatility surfaces’ shapes and absolute values are compared in between models but also within models for some of the best-fit producing parameter sets. The surfaces are found to differ in both cases for some strike and maturity combinations - sometimes with relative differences of more than 10%. This suggests that surfaces with good fits to the input data still can produce distinctly differing prices for some options. Calibrating the models with the chosen approach involves calculations with complex numbers in ways which potentially introduce problematic discontinuities due to branch crossings. This is investigated numerically as well as theoretically for the 4 models and found to be a significant problem in one of them. The three other models are found to avoid these problems under all valid parameter sets.

Abstract:
Digital notes have numerous advantages compared to analog notes, yet the will to use pen and paper remains. Thus, a need to digitize handwritten notes arises. To make it as simple as possible a minimum amount of user interaction should be required. The aim of this project is to present a process of automated image capturing, followed by a process of automatic image stitching, given photos taken by a camera which is moved parallel to a whiteboard or similar planar scenery. The need stems from being able to obtain higher image quality than possible using only one overall picture. The processes is to be executed on mobile devices, with comparatively low computational capacity, within a reasonable time interval. A review and theoretical analysis is conducted of existing methods for all parts of the processes: automated image capturing, registration, reprojection and blending. The methods considered appropriate for further use are evaluated in the form of a series of tests developed for the purpose with focus on the balance between robustness, which ultimately means visual accuracy in the final image, and computation intensity. The techniques evaluated are based on feature points which are used to calculate a transformation homography. Also, two new techniques are presented and evaluated. One for finding features in the form of corners by approximating shapes into polygons. The other method is used to speed up the image matching process from a camera feed towards a given image by reducing the search space by using the former transient image from the camera feed. The results show that it is feasible to assemble correct image compositions despite that the intended sceneries often contain few features; a bigger problem is that they often are poorly distributed. The difference in quality between the corresponding evaluated techniques is small in comparison to the speed differences. With a combination of fast algorithms, including the proposed speed up, it is possible to achieve a holistic process working viable on standard mobile devices. To optimize the stitching process an alternative method is proposed utilising dynamic criteria for when a new image should be stored during the automated capturing.
Digitala anteckningar har flera fördelar gentemot analoga, men viljan att använda penna och papper kvarstår. Därmed uppkommer ett behov av att digitalisera handskrivna anteckningar. För att det ska vara så enkelt som möjligt är målet minsta möjliga antal interaktioner med användaren. Syftet med projektet är att presentera en process för automatiserad bildtagning för bilder tagna av en kamera som flyttas parallellt med en whiteboardtavla, eller liknande scenbild, följt av en process för automatisk sammanfogning av dessa bilder. Problemet ligger i behovet av att få högre kvalitet i den slutgiltiga bilden än vad som är möjligt med enbart en övergripande bild. Processerna ska exekveras på mobila enheter, med jämförelsevis låg beräkningskapacitet, inom ett rimligt tidsintervall. En genomgång och teoretisk analys utförs av befintliga metoder för alla delar av processen: automatiserad bildtagning, registrering, omprojecering samt färgutjämning. De metoder som bedöms ändamålsenliga utvärderas vidare i form av en serie tester utvecklade för ändamålet där fokus ligger på avvägningen mellan robusthet, vilket i förlängningen innebär visuell korrekthet i den slutgiltiga bilden, samt beräkningsintensitet. Teknikerna som utvärderas baseras på intressepunkter vilka används för att beräkna en omvandlingshomografi. Även två nya tekniker presenteras och utvärderas. Den ena för att hitta intressepunkter i form av hörn genom att approximera former till polygoner. Den andra metoden används för att snabba upp matchningsprocessen från ett kameraflöde mot en given bild genom att minska sökrymden med hjälp av föregående bild från kameraflödet. Resultaten visar att det är möjligt att foga samman korrekta bildkompositioner trots att de avsedda scenbilderna ofta innehåller få intressepunkter; ett större problem är att de ofta har dålig spridning. Skillnaden i bildkvalitet mellan de utvärderade teknikerna är små i jämförelse med hastighetsskillnaderna. Med en kombination av snabba algoritmer, inklusive den föreslagna uppsnabbningen, är det möjligt att åstadkomma en helhetsprocess som fungerar dugligt på vanliga mobila enheter. För att optimera bildsammanfogningen föreslås en alternativ metod med dynamiska kriterier för när en ny bild ska sparas under den automatiserade bildtagningen.

Abstract:
Live Surface allows users to segment and render complex surfaces from 3D image volumes at interactive (sub-second) rates using a novel, Cascading Graph Cut (CGC). Live Surface consists of two phases. (1) Preprocessing for generation of a complete 3D watershed hierarchy followed by tracking of all catchment basin surfaces. (2) User interaction in which, with each mouse movement, the 3D object is selected and rendered in real time. Real-time segmentation is ccomplished by cascading through the 3D watershed hierarchy from the top, applying graph cut successively at each level only to catchment basins bordering the segmented surface from the previous level. CGC allows the entire image volume to be segmented an order of magnitude faster than existing techniques that make use of graph cut. OpenGL rendering provides for display and update of the segmented surface at interactive rates. The user selects objects by tagging voxels with either (object) foreground or background seeds. Seeds can be placed on image cross-sections or directly on the 3D rendered surface. Interaction with the rendered surface improves the user's ability to steer the segmentation, augmenting or subtracting from the current selection. Segmentation and rendering, combined, is accomplished in about 0.5 seconds, allowing 3D surfaces to be displayed and updated dynamically as each additional seed is deposited. The immediate feedback of Live Surface allows for the segmentation of 3D image volumes with an interaction paradigm similar to the Live Wire (Intelligent Scissors) tool used in 2D images.

Abstract:
This thesis is concerned with the chemical modification of polymers in the preparation of a library of materials which exhibit altered surface properties as a result of the surface chemical functionality, with particular emphasis on the development of materials that control biofouling and are antibacterial. Chemical modification of crosslinked polystyrene, in film and microsphere form, was carried out by carbene insertion followed by diazonium coupling. This provided access to a collection of materials with varying surface chemistry, whilst the bulk properties of the polystyrene substrates were maintained. Synthesis of the diaryldiazo and the diazonium salts used to perform the surface modifications is described, as well as the preparation and characterisation of the materials. Analysis of the ability of the materials to adsorb and bind the protein bovine serum albumin (BSA) is presented with data obtained from two methods of observation. Quartz Crystal Microbalance with Dissipation (QCM-D) and a protein assay based on the change in optical density of a BSA/PBS solution are used to demonstrate how the specific surface chemistry of the materials influences the ability to adsorb and bind protein. The behaviour of the materials was time dependent and was rationalised with respect to the surface water contact angle and the calculated parameters polar surface area and % polar surface area of the functional groups added to the surfaces. Finally, penicillin loaded materials were prepared and their antibacterial activity was tested against E. coli and S. aureus, demonstrating that the antibiotic is still active from within the polystyrene scaffold.

Abstract:
Software Configurable Optical Test System (SCOTS) developed at University of Arizona is a highly efficient optical metrology technique based on the principle of deflectometry, which can achieve comparable accuracy with interferometry but with low-cost hardware. In a SCOTS test, an LCD display is used to generate structured light pattern to illuminate the test optics and the reflected light is captured by a digital camera. The surface slope of test optics is determined by triangulation of the display pixels, test optics, and the camera. The surface shape is obtained by the integration of the slopes. Comparing to interferometry, which has long served as an accurate non-contact optical metrology technology, SCOTS overcomes the limitation of dynamic range and sensitivity to environment. It is able to achieve high dynamic range slope measurement without requiring null optics. In this dissertation, the sensitivity and performance of the test system have been analyzed comprehensively. Sophisticated calibrations of system components have been investigated and implemented in different metrology projects to push this technology to a higher accuracy including low-order terms. A compact on-axis SCOTS system lowered the testing geometry sensitivity in the metrology of 1-meter highly aspheric secondary mirror of Large Binocular Telescope. Sub-nm accuracy was achieved in testing a high precision elliptical X-ray mirror by using reference calibration. A well-calibrated SCOTS was successfully constructed and is, at the time of writing this dissertation, being used to provide surface metrology feedback for the fabrication of the primary mirror of Daniel K. Inouye Solar Telescope which is a 4-meter off-axis parabola with more than 8 mm aspherical departure.

Abstract:
Saturn's moon, Titan is a geomorphologically active planetary object, and its surface is influenced by multiple processes like impact cratering, fluvial and aeolian erosion, lacustrine processes, tectonics, cryovolcanism and mantling. Disentangling the processes that compete to shape Titan's landscape is difficult in the absence of global topography data. In this thesis, I utilize techniques in topographic statistics, fractal theory, study of terrestrial analogs and landscape evolution modeling to characterize Titan's topography and surface roughness and investigate the relative roles of surface processes in sculpting its landscape. I mapped the shorelines of 290 North Polar Titanian lakes using the Cassini Synthetic Aperture Radar dataset. The fractal dimensions of the shorelines were calculated via the divider/ruler method and box-counting method, at length scales of (1-10) km and found to average 1.27 and 1.32, respectively. The inferred power-spectral exponent of Titan's topography (β) was found to be ≤ 2, which is lower than the values obtained from the global topography of the Earth or Venus. In order to interpret fractal dimensions of Titan's shorelines in terms of the surficial processes at work, I repeated a similar statistical analysis with 114 terrestrial analogous lakes formed by different processes, using C-band radar backscatter data from the Shuttle Radar Topography Mission (SRTM). I found different lake generation mechanisms on Earth produce 'statistically different' shorelines; however, no specific set of processes could be identified for forming Titanian lake basins. Using the Cassini RADAR altimetry data, I investigated Titan's global surface roughness and calculated median absolute slopes, average relief and Hurst exponent (H) for the surface of Titan. I detected a clear trend with latitude in these roughness parameters. Equatorial regions had the smallest slopes, lowest values of H and smallest intra-footprint relief, compared to the mid-latitudes and polar regions of Titan. I used steady state models of relief generation (tectonic activity) and relief reduction (diffusive mass wasting and advective bedrock channel erosion) to generate synthetic landscapes and simulate Titan's topography. I provided constraints on two environmental variables for Titan that influence surface roughness: diffusivity and erodibility coefficient.

Moore, Kathleen Dorothy. "The Impact of Surface Normals on Appearance." W&M ScholarWorks, 2016. https://scholarworks.wm.edu/etd/1477068344.

Abstract:
The appearance of an object is the result of complex light interaction with the object. Beyond the basic interplay between incident light and the object's material, a multitude of physical events occur between this illumination and the microgeometry at the point of incidence, and also beneath the surface. A given object, made as smooth and opaque as possible, will have a completely different appearance if either one of these attributes - amount of surface mesostructure (small-scale surface orientation) or translucency - is altered. Indeed, while they are not always readily perceptible, the small-scale features of an object are as important to its appearance as its material properties. Moreover, surface mesostructure and translucency are inextricably linked in an overall effect on appearance. In this dissertation, we present several studies examining the importance of surface mesostructure (small-scale surface orientation) and translucency on an object's appearance. First, we present an empirical study that establishes how poorly a mesostructure estimation technique can perform when translucent objects are used as input. We investigate the two major factors in determining an object's translucency: mean free path and scattering albedo. We exhaustively vary the settings of these parameters within realistic bounds, examining the subsequent blurring effect on the output of a common shape estimation technique, photometric stereo. Based on our findings, we identify a dramatic effect that the input of a translucent material has on the quality of the resultant estimated mesostructure. In the next project, we discuss an optimization technique for both refining estimated surface orientation of translucent objects and determining the reflectance characteristics of the underlying material. For a globally planar object, we use simulation and real measurements to show that the blurring effect on normals that was observed in the previous study can be recovered. The key to this is the observation that the normalization factor for recovered normals is proportional to the error on the accuracy of the blur kernel created from estimated translucency parameters. Finally, we frame the study of the impact of surface normals in a practical, image-based context. We discuss our low-overhead, editing tool for natural images that enables the user to edit surface mesostructure while the system automatically updates the appearance in the natural image. Because a single photograph captures an instant of the incredibly complex interaction of light and an object, there is a wealth of information to extract from a photograph. Given a photograph of an object in natural lighting, we allow mesostructure edits and infer any missing reflectance information in a realistically plausible way.
