Strategic Design Of Service Orientated Web-Based Supply Chain Infrastructure, Leone J. Dunn, Peter R. Gibson

Peter R Gibson

The traditional 'make and sell' attitude of industrial manufacturing organisations has now almost entirely given way to customer orientated 'sense and respond' service philosophies to the extent where this has become a major competitive key success factor in a global manufacturing industry. In order to become service orientated, manufacturing industry is increasingly dependent on efficient and effective supply relationships. This trend is compounded by needs for waste avoidance, minimal inventory, cost efficiency and appropriate service to the customer. This paper considers the strategic opportunities for large engineering project firms that have identified a need to establish advantages over their competitors …

Product Display Versus Graphical Representation On Packaging, Joshua Galvarino

All Theses

ABSTRACT
Previous research conducted (Hurley, et al., 2012) concerning physical and graphical product visibility from the primary display panel (PDP) is limited to one product category. This research expands previous peer-reviewed research, which indicates that there is a significant difference between consumer preferences of graphical display vs. physical product display on packaging.
The shelf presence of packages showing actual product visibility versus packages showing only a graphical representation of the product was evaluated. Both shopping results and quantitative data using eye-tracking technology were collected and cross-referenced with a qualitative, post-experiment survey.
Specifically, variables of packaging within pasta, snacks, prepared frozen …

Design And Implementation Of Edge Detection Algorithm In Dspic Embedded Processor, Prashan Premaratne, Sabooh Ajaz, Ravi Monaragala, Nalin Bandara, Malin Premaratne

Dr Prashan Premaratne

The research presented here is an attempt to use a very basic, low cost and non-specialized microcontroller for image processing tasks. The applications emanating from such an attempt will result in inexpensive face detection, intelligent motion sensors to low cost vehicle counting systems. We have been able to develop a system based on Microchip dsPIC microcontroller that implements edge detection of still images. Hardware-based signal processors such as Texas Instrument DSP (Digital Signal Processing) or Field Gate Arrays (FPGA) are generally an expensive solution for image processing applications. On the other hand a conventional 8-bit microcontroller doesn’t have enough capability …

Conversations Around Design Sketches: Use Of Communication Channels For Sharing Mental Models During Concept Generation, Nik Shahman Nik Ahmad Ariff, Petra Badke-Schaub, Ozgur Eris

Ozgur Eris

In this paper, we present an exploratory protocol study on the use of different communication channels during design sketching. We focus on how individual designers share their mental models with other designers in a group, and analyse their use of graphical, textual, and verbal communications during concept generation.

Our findings suggest that verbal communication plays a role in the sharing of individual mental models during sketching, and complements graphical and textual communication channels. However, design teams can still function without verbal communication in that respect, and address design problems. They seem to compensate for the absence of the verbal communication …

Multi-Objective Optimization Of Wind Farm Layouts Under Energy Generation And Noise Propagation, Cristina Amon, Wing Yin Kwong, Joaquin Moran, Michael Morgenroth, David Romeo, Peter Y. Zhang

Publications and Scholarship

Wind farm design deals with the optimal placement of turbines in a wind farm. Past studies have focused on energymaximization, cost-minimization or revenue-maximization objectives. As land is more extensively exploited for onshore wind farms, wind farms are more likely to be in close proximity with human dwellings. Therefore governments, developers, and landowners have to be aware of wind farms’ environmental impacts. After considering land constraints due to environmental features, noise generation remains the main environmental/health concern for wind farm design. Therefore, noise generation is sometimes included in optimization models as a constraint. Here we present continuous-location models for layout optimization …

Best Source For Patent Drawing Rules & Regulations, Bernadette Marshall

Bernadette Marshall

It is with great pleasure that I announce something new from NBG-Drafting and Design. This is our first Newsletter - Special Edition; In this edition we will cover our preferred sources for patent drawing rules & regulations. Finding resources for information regarding patent drawing rules can be frustrating. Much of the information refers to out-of-date methods, like hand drawings using ink pens on board. It is hard to imaging creating any type of mechanical/technical drawings today without the use of CADD (software application for computer aided design and drafting). Most skilled patent draftspersons today are practicing in CADD.

Novel Tooth Design For A Tubular Linear Motor For Machine Tool Axis, Philip Commins, Jeffrey Moscrop, Christopher Cook

Christopher Cook

Permanent magnet tubular linear motors have shown potential for use as direct drives in high precision machine tools. These devices are capable of replacing the traditional ball screw, given their ability to overcome or reduce many of the fundamental mechanical properties that limit the precision performance of the ball screw. However, given the desire from industry to increase speed and acceleration, the physical size of the motor must be minimised while maintaining high force output to increase bandwidth in high precision applications. This paper presents a new optimal tooth design to reduce the frame size of a slotted tubular linear …

Design And Simulation Of Roadway Development Operations To Improve Productivity, Soumya Raghavendra Rao, Christopher D. Cook, Ernest Y. Baafi, R Porteous

Christopher Cook

A typical Australian 3–5 Mt/year longwall requires 9 to 15 km of roadway to be developed every year (G. Lewis and G. Gibson: Proc. 13th Austr. Tunnelling Conf., Melbourne, Australia, May 2008, ATS, 317–326.). One of the major challenges faced by the Australian longwall mining industry is that roadway development has been unable to keep pace with improvements in longwall extraction rates. This has affected the profitability, viability and future of underground coal mines (M. Kelly: 'Coordination of roadway development strategy', ACARP report no. C5013, ACARP, Brisbane, Australia, 1997.). Gibson (G. Gibson: 'Australian roadway development– current practices', ACARP report no. …

Investigation Of Prototype Roles In Conceptual Design Using Case Study And Protocol Study Methods, Timothy Hess

All Theses

Prototypes play an important role in the engineering design process. Engineering design textbooks often discourage the use of prototypes early in the design process, citing past research on prototypes in engineering design has focused describing and classifying the prototypes themselves. The gap in this research is the investigation of prototyping processes. While researchers have studied the characteristics of different prototypes and in some cases have tried to tie characteristics to the outcomes of the design process, the actual prototyping activities and the process of building and using the prototypes has not been studied in detail. The work presented in this …

A Semi-Automatic Approach For Project Assignment In A Capstone Course, Mark Chang, Allen Downey

Mark L. Chang

This paper presents a semi-automatic approach to assigning students to project teams for a year-long, industry-sponsored senior capstone course. Successful assignment requires knowl- edge of at least individual project requirements, student skills, student personalities, and student project preferences. This mix of hard skills, soft skills, and interpersonal impres- sions requires human involvement to produce a high-quality assignment. The importance of faculty input often requires that the assignment process be labor- and time-intensive.

Our approach attempts to reduce the time required to perform this assignment by selectively automating parts of the task flow. An automated search uses a randomized greedy algorithm …

Mechanical Properties And Mems Applications Of Carbon-Infiltrated Carbon Nanotube Forests, Walter C. Fazio

Theses and Dissertations

This work explores the use of carbon-infiltrated carbon nanotube (CI-CNT) forests as a material for fabricating compliant MEMS devices. The impacts of iron catalyst layer thickness and carbon infiltration time are examined. An iron layer of 7nm or 10nm with an infiltration time of 30 minutes produces CI-CNT best suited for compliant applications. Average maximum strains of 2% and 2.48% were observed for these parameters. The corresponding elastic moduli were 5.4 GPa and 4.1 GPa, respectively. A direct comparison of similar geometry suggested CI-CNT is 80% more flexible than single-crystal silicon. A torsional testing procedure provided an initial shear modulus …

Concrete Design For Traffic Application, Marc Shields

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Inductive charging of electronic devices is a newer technology that is capable of transferring electrical power without physical contact through wiring. Research is currently being done to find and improve ways to implement this technology on electric cars. If this type of technology pas implemented on a large scale throughout much of the country, electrical or hybrid cars could travel across counties and states without depleting their batteries.

The current problem with electric cars is that they have a limited range of travel. Even with larger batteries with much more capacitance, the range of pure electric cars usually does not …

Finite Element Modeling And Design Of Honeycomb Sandwich Panels For Acoustic Performance, David Griese

All Theses

Honeycomb cellular metamaterial structures offer many distinct advantages over homogenous materials because their effective material properties depend on both their constituent material properties and their geometric cell configuration. From this, a wide range of targeted effective material properties can be achieved thus supporting forward design by tailoring the honeycomb cellular materials and properties for specific applications. One area that has not been fully explored is the set of acoustic properties of honeycomb materials and how these can offer increased design flexibility when targeting acoustic performance. Understanding these relations, the designer can effectively tune designs to perform better in specific acoustic …

Sun-Synchronous Orbit Slot Architecture Analysis And Development, Eric Watson

Master's Theses

Space debris growth and an influx in space traffic will create a need for increased space traffic management. Due to orbital population density and likely future growth, the implementation of a slot architecture to Sun-synchronous orbit is considered in order to mitigate conjunctions among active satellites. This paper furthers work done in Sun-synchronous orbit slot architecture design and focuses on two main aspects. First, an in-depth relative motion analysis of satellites with respect to their assigned slots is presented. Then, a method for developing a slot architecture from a specific set of user defined inputs is derived.

Repairing Mixed-Conducting, Ceramic Electrolyte Films, Kevin Tolman, Izaak Williamson, Kokfoong Chan

College of Engineering Poster Presentations

Ceramatec, Inc. develops ceramic-electrolyte thin films for gas separation/purification technologies. Specific ions (e.g., oxygen) can be selectively diffused through these films in order to obtain a desired product, such as syngas or pure O2. During production, residual stresses develop within the films which induce defects, such as pinholes, micro-cracks, and other sources of leaks, that allow gas contamination. To improve large-scale film production yield, four application techniques were analyzed for their feasibility of restoring the integrity of the films. Controlled, uniform defects were introduced to the films using a microindenter to enable an effective comparison of application techniques …

Information And Communications Technology For Development (Ict4d) – A Design Challenge?, Rahul Tongia, Eswaran Subrahmanian

Eswaran Subrahmanian

In this paper, we make the case that ICT projects in the developed and developing world often lead to partial or total failures due to the incomplete assessment of the problem being solved and the metrics used to evaluate solutions. While in the developed world the success of ICT solutions are often determined by the market, with available infrastructure and market mechanisms, in the developing world this ecosystem does not exist thus requiring an understanding of the ecosystem in which ICT solutions are to be applied. Using literature from the design space, and experiences in ICT for development, we elaborate …
