Design For Movement: Block Pattern Design For Stretch Performancewear
Pattern drafting techniques for woven block patterns have been well established. Applying existing techniques with modifications to generate patterns for modern stretch fabrics can be successful but it is often at a cost. In the development of a stretch pattern, an acceptable fit cannot be …

The influence of woven stretch fabric properties on pattern design.
Conventional pattern construction and pattern making methods typically require the size measurements of a range of standard mannequins or human bodies in order to construct the varying pattern blocks for garment design. These various methods and skills, in the fashion industry, factory or studio …

A beam pattern design procedure for multidimensional sonar arrays employing minimum variance beamforming
This paper develops a beam pattern design procedure for general multidimensional irregular sonar arrays that incorporates the not well understood effects of array geometry into the design process. The procedure is implemented by generating a "penalty function" in a spectral covariance function …

Binder Infill Pattern Design Strategies for Increased Mechanical Properties in Binder Jet Additive Manufacturing Parts
… green and sintered properties through binder pattern manipulation (i.e., toolpathing) and (ii) gain an understanding of their corresponding process-structure-property relationships. Specifically, the author explores three distinct strategies for binder jetted 316L: (1) architected lattice …

Application of electromagnetic-bandgap structures to power distribution network design
… a detailed literature review and an original pattern design example of the application of an electromagnetic bandgap structure which suppresses the simultaneous switching noise in a power distribution network. By accommodating a metalized periodic pattern on either power or ground plane, the …

The BoPen : a tangible pointer tracked in six degrees of freedom
In this thesis, I designed and implemented an optical system for freehand interactions in six degrees of freedom. A single camera captures a pen's location and orientation, including roll, tilt, x, y, and z by reading information encoded in a pattern at the infinite focal plane. The pattern design, …

Optimization of Patterned Surface Structures
… advances a recent work on the optimization of patterned surface structures used for architecture and structural engineering. On their own, well-designed surface structures--such as plates and shells--can be highly efficient, but by introducing specific aperture patterns, designers can further …

The development of an educational computer aided design system for garment manufacture
A computer aided design (CAD) system for the design of flat patterns for female clothing has been developed specifically for use in an Educational environment. This Pattern Making System (PMS) has been developed using a commercial computer aided design software system, CADDS 4X, originally marketed …

Computational Exploration of Origami Tessellation Design:Harnessing Shape Grammar for Flexible Folding Structures
Origami tessellation, with its intricate folding patterns, presents a unique blend of artistic expression and engineering application. However, the design process often proves daunting due to its complexity, limiting accessibility to enthusiasts and impeding its potential impact in engineering and …

Tension-induced tunable corrugation in two-phase soft composites and its properties as a band gap structure
… properties as a band gap structure. By carefully designing the inclusion pattern, it is possible to induce corrugations normal to the direction of stretch. By stacking 1D composite fibers to form 2D membranes, these corrugations collectively lead to the formation of membrane channels with shapes …

Proton-Implanted Photonic Crystal and Holey Vertical -Cavity Surface -Emitting Lasers
… holes are etched a variety of depths for various designs to study the influence on single-mode emission. To investigate both the index confinement provided by the etched pattern and its effect on optical loss, continuous-wave and pulsed excitation experiments are performed. It is shown that proper …

Design and the formation of taste in the British printed calico industry, 1919 to 1940
… and the contemporary ideological construction of pattern design. The thesis tests several historiographic views relevant to the structural analysis of taste formation. The assertion by the Balfour Committee in 1928 that the industry was divided into separate market and design style sections is …

A notion of a system pattern (tri-integration) and its instantiation in enterprise application development
… growth. This thesis investigates how a system pattern can help software development according to a piecemeal growth approach. Firstly, a new concept for software development, a system pattern, is proposed. It describes a particular recurring development problem that arises in specific …

Surrogate Model Optimisation for PWR Fuel Management
… and changing goals mean that fuel loading pattern design problems are multiobjective and, by design, have many input variables. This causes a combinatorial explosion, known as the ‘curse of dimensionality’, which makes these complex problems difficult to investigate. In this thesis, the …

Optimizing Laser and Liquid Nitrogen Treatments for Weed Control in Turfgrass Systems
… turfgrass weeds: cryogenic liquid exposure and patterned laser energy. In the cryogenic study, a custom-built applicator was used to deliver precise doses of liquid nitrogen (LN) to individual plants of goosegrass (Eleusine indica) and annual bluegrass (Poa annua). Four field trials were …
