In And Out Line Monitoring System For Volleyball, Kelley White

Honors Theses

The main goal of this project is to create a line monitoring system for volleyball to aid the line judges in their decision making as well as reduce the frequently misjudged calls. Line calling systems have already been implicated into other sports but there is not one yet for volleyball. This is because volleyball must move on to the next point in a matter of seconds or a delay of game is called against a team. Therefore, there needs to be a system that calls a ball without the need of a replay. The in and out line monitoring system …

Orthogonal Experimental Design Of Titanium Dioxide - Poly(Methyl Methacrylate) Electrospun Nanocomposite Membranes For Photocatalytic Applications, Andrew Vild, Sara Teixeira, Klaus Kuhn, Gianaurelio Cuniberti, Vitor Sencadas

Faculty of Engineering and Information Sciences - Papers: Part A

An orthogonal experimental method was designed to assess the influence of the electrospinning processing parameters on average diameter and distribution of poly(methyl methacrylate) (PMMA) fibers. Based on the orthogonal experimental design analysis, electrospun TiO2-PMMA nanocomposites were processed with the optimal polymer processing conditions to obtain thin fibers with a high overall surface area. Further it was found that the average fiber diameter decreases from 2.0 ± 0.5 down to 1.2 ± 0.2 μm with increasing photocatalyst content. Moreover, the wettability of samples was independent of the filler amount, and showed strong hydrophobic behavior. Thermogravimetric analysis showed that for polymer solutions …

Optimal Design Of Fixture Layout In A Multi-Station Assembly Using Highly Optimized Tolerance Inspired Heuristic, Satish Tyagi, Nagesh Shukla, Sumant Kulkarni

Faculty of Engineering and Information Sciences - Papers: Part A

The multi-station assembly (MSA) process requires auxiliary devices such as fixtures and clamps to accurately locate and firmly hold the workpiece in a desired position. Improper positioning of these fixtures and clamps affects the dimensional integrity of final product. This study determines the optimal design of fixture layout that minimizes the product dimensional variations caused by the manhandling and aging of auxiliaries. In order to model variation propagation from one assembly station to another in the MSA, a state space model is employed. Further, an E-optimality based sensitivity criterion is proposed to mathematically formulate and measure the quality of the …

Design-Oriented Stress–Strain Model For Concrete Under Combined Frp-Steel Confinement, G Lin, Tao Yu, Jin Guang Teng

Faculty of Engineering and Information Sciences - Papers: Part A

Extensive research has been conducted on fiber-reinforced polymer (FRP)-confined plain and RC columns, leading to a large number of stress–strain models. Most of these models have been developed for FRP-confined plain concrete and are thus applicable only to concrete in FRP-confined RC columns with a negligible amount of transverse steel reinforcement. The few models that have been developed for concrete under the combined confinement of FRP and transverse steel reinforcement are either inaccurate or too complex for direct use in design. This paper presents an accurate design-oriented stress–strain model for concrete under combined FRP-steel confinement in FRP-confined circular RC columns. …

Exploring Virtual World Innovations And Design Through Learner Voices, Sue Gregory, Brent Gregory, Marcus Mcdonald, Sasha Nikolic, Helen Farley, Judy O'Connell, Des Butler, Lisa Jacka, Scott Grant, Jay Jay Jegathesan

Faculty of Engineering and Information Sciences - Papers: Part A

Student voice has played a big role in shaping the development and measure of success/failure of virtual worlds in education. Data on past and ongoing educational uses and contexts of use of virtual worlds and associated student feedback was gathered via a survey of educational researchers specialising in virtual worlds. Introduced are a range of specific uses that provide the source of and context for student feedback. Ten major themes emerged from student voices that highlight strengths and weakness and point the way forward for both educators and the students themselves. Positive feedback highlighted experiences of both pedagogical design and …

Thermal Performance Evaluation And Optimal Design Of Buildings With Integrated Air-Based Photovoltaic Thermal Collectors And Phase Change Materials Using The Hooke-Jeeves Pattern Search Method, Wenye Lin, Zhenjun Ma, Paul Cooper

Faculty of Engineering and Information Sciences - Papers: Part A

Over the last several decades, many low energy technologies have been developed and deployed to reduce building energy consumption. Among various solutions, solar photovoltaic thermal (PVT) collectors and phase change materials (PCMs) are among the most promising methods receiving increasing attention. This paper presents a thermal performance evaluation and optimal design of buildings integrated with air-based solar PVT collectors and PCMs embedded in the building envelope by using The Hooke-Jeeves pattern search method. The Hooke-Jeeves generalized pattern search is used to search for optimal solutions of the optimization problem. The variables optimized include the PVT air flow rate, additional wall …

Design And Development Of A Parametrically Excited Nonlinear Energy Harvester, Tanju Yildirim, Mergen H. Ghayesh, Weihua Li, Gursel Alici

Faculty of Engineering and Information Sciences - Papers: Part A

An energy harvester has been designed, fabricated and tested based on the nonlinear dynamical response of a parametrically excited clamped-clamped beam with a central point-mass; magnets have been used as the central point-mass which pass through a coil when parametrically excited. Experiments have been conducted for the energy harvester when the system is excited (i) harmonically near the primary resonance; (ii) harmonically near the principal parametric resonance; (iii) by means of a non-smooth periodic excitation. An electrodynamic shaker was used to parametrically excite the system and the corresponding displacement of the magnet and output voltages of the coil were measured. …

The Future Of Arabic Music: No Sound Without Silence, Nesma Magdy Khodier Vcuq

Theses and Dissertations

For centuries, Arabic music has been intrinsically linked to Arab culture and by extension bonded to the environmental landscape of the region, reflecting their emotions, moods, and behaviors. Numerous technological advancements in the latter half of the twentieth century, have greatly affected the rich legacy of Arabic music, significantly impacting the natural progression of traditional Arabic musical genres, scales, and instrumentation.

This thesis serves as an introduction to generative methods of music production, specifically music generated through gestures. Through generative music, and its unique ability to map gestures to different musical parameters, music can be produced using computer algorithms.
