Sliding contact at plastically graded surfaces and applications to surface design
… is known to offer avenues for suppressing surface damage during normal indentation and sliding contact. These graded materials have potential applications in diverse areas such as barrier coatings for structural components and industrial tools. The gradient in plastic properties is of …

Brief encounter : transformation of space underneath elevated expressway through surface design
… spatial qualities through various building skin/surface designs. The design concepts are guided by five parameters: usage, pattern of movement, light, acoustics, and materials. The use of natural and light-weight materials (bamboo, polycarbonate, water) is given priority. The topography generated …

Response Surface Design and Analysis in the Presence of Restricted Randomization
… costly-to-change factors. Employing a split-plot design structure minimizes the number of required experimental settings for the hard-to-change factors. In this research, we propose classes of equivalent estimation second-order response surface split-plot designs for which the ordinary least …

Tlingit tunic design: visual definition, meaning, and identity
… viewing. The viewing relationships of interior design lines, silhouette, and surface design readily organized appearance into visual categories. The models were further divided into subsections which displayed information on a particular part of the tunic (for example, side silhouette shapes). …

Wetting hysteresis and droplet roll off behavior on superhydrophobic surfaces by Katherine Marie Smyth.
… when water droplets are deposited on micro-post surfaces of different post densities. Hysteresis is commonly defined as the difference between the advancing and receding contact angle and after many decades of research, the mechanisms governing hysteresis are still not fully understood. …

High-order adaptive methods for computing invariant manifolds of maps
… number of points needed to compute a given curve/surface, he proposes using higher-order interpolation/approximation techniques from geometric modeling. He uses Bezier curves/triangles, fundamental objects in curve/surface design, to create adaptive methods. The methods are based on tolerance …

Competitive interactions and community influences among invasive and native fishes at different spatial scales
… In the first experiment, I used a response surface design to independently vary the densities of bighead carp and bluegill in mesocosms. This design allowed for the investigation of inter- and intra-specific competitive interactions for both species, as well as the influences of the fishes …

Distributed & conceptual CAD (DC-CAD) : a new software solution for product design
Many computer aided design (CAD) software packages focus on detailed design and not on early stage, conceptual design. The ability to conceptualize and sketch early versions of a product solution is currently limited to paper and pencil or to inadequate computer-aided industrial design programs …

Interactions at interfaces across scales : from adsorption to adhesion
… on substrates to the adhesion of ice on solids. Surface engineering is used to tailor the physicochemical properties of surfaces (microstructure, roughness, chemical functionalization, and charge) to achieve the desired behavior. First, macroscopic features are introduced on superhydrophobic …

Micro and nanostructured surfaces for enhanced phase change heat transfer
… geometry on liquid transport behavior. We designed and fabricated asymmetric nanostructured surfaces where nanopillars are deflected with angles ranging from 7 -52'. Uni-directional liquid spreading was demonstrated where the liquid propagates in a single preferred direction and pins in all …

Optimal experimental designs for estimating the slope of a response surface
… criteria for the selection of a response surface design have been presented by many authors. For the most part these criteria have led to optimal designs for predicting response. In many applications of response surface methodology, however, the primary experimental objective can best be …

Contact Pressure Distribution Optimization
A novel design technique that is used to optimize contact pressure distribution was introduced and investigated. The primary objective of this design tool, called the Predicted Displacement Method, was to provide a calculated contact surface shape alteration of a contact body that induces a uniform …

Analysis and design of composite curved frames
In this work, methods for rapid analysis and design of composite curved C-section frames subjected to axial tensile loading are developed. Failure is predicted using polynomial in-plane and interlaminar failure criteria. Interlaminar stresses can be directly computed only from three-dimensional …
