Research On Development And Application Of Simulated Night Vision Enhancement Systems, Linzhen Nie

Mechanical Engineering Dissertations

Poor visibility due to darkness is believed to be one of the main causes for the high rate of night driving accidents.

Night vision enhancement systems (NVESs) have been developed to improve visibility at night through supplementing drivers' direct vision with additional information shown on a display, rather than replacing drivers' direct vision. Existing studies have shown that NVESs may increase recognition distance, but may also increase drivers' mental and visual distraction (eyes-off-road). Each scan of the display of the night vision enhancement system involves some visual and mental cost to the driver. Automatic pedestrian warnings (APWs) have been integrated ...

Astaxanthin: A Comparative Case Of Synthetic Vs. Natural Production, Khoa Dang Nguyen

Chemical and Biomolecular Engineering Publications and Other Works

Astaxanthin, the “king of carotenoids” has been widely used as an animal feed additive for several decades, mainly in the aquaculture industry. Recent studies have led to its emergence as a potent antioxidant available for human consumption. Traditionally it has been chemically synthesized, but the recent market interest has generated interests in producing it naturally via yeast (Phaffia rhodozyma) fermentation, or algal (Haematococcus pluvialis) induction. This work aims to compare these production processes and their impact on the economical, environmental, and societal scale. We also look at the attempts of increasing production yields by altering various parameters during all three ...

The People Dimension In Logistics And Supply Chain Management – Its Role And Importance, Edward Sweeney

Books/Book chapters

It is widely recognised that the effective application of logistics and supply chain management (SCM) has a vital role to play in European economic recovery. Experience suggests that success in achieving higher levels of supply chain integration (SCI) depends on both physical and technical components (the hard-wiring), as well as human and behavioural components (the soft-wiring). There is significant evidence that the latter has been largely neglected by the logistics and SCM community. Furthermore, it appears that the majority of supply chain improvement initiatives by practitioners have been primarily concerned with technological, structural and process issues. This chapter argues that ...

Participatory Development Of Ergonomic Design-For-Fixture Guidelines - A Case Study, Judy Village, Michael Greig, Patrick Neumann

Industrial Engineering Publications and Research

This paper describes one initiative in a 3-collaboration between RIM and Ryerson University, the goal of which is to integrate human factors (HF) considerations early in design of assembly production lines. The RIM-Ryerson steering group suggested this initiative because the engineering group was formalizing their fixture development process with the goal of improving the quality and timeline for design. To incorporate HF into design, research has suggested that the combination of a few specific HF design criteria and active involvement of HF specialists are both critical for positive outcomes. In this initiative, Ergonomists analyzed current fixtures for ergonomics-related concerns. These ...

Supply Chain "Mega-Trends": Current Status And Future Trends, Edward Sweeney

Practitioner Journals

The supply chain management (SCM) concept has become embedded in the thinking of many organisations in recent years. Originally introduced by management consultants in the early 1980s, SCM has a strong focus on integration of processes across functions within firms, as well as between the organisations that comprise the wider extended enterprise. There is a significant body of research to support the notion that the consistent delivery of value to customers is predicated on higher levels of intra-firm and inter-firm integration. Putting the supply chain integration (SCI) concept into practice is critically dependent on the ability of firms to manage ...

Hybrid Agent Based Simulation With Adaptive Learning Of Travel Mode Choices For University Commuters, Nagesh Shukla, Albert Munoz, Jun Ma, Nam Huynh

Nagesh Shukla

This paper presents a methodology for developing a hybrid agent-based micro-simulation model to capture the impacts of commuter travel mode choices on a University campus transport network. The proposed methodology involves: (i) developing realistic population of commuter agents (students and staff); (ii) assigning activity lists and travel mode choices to agents using machine learning method; and, (iii) traffic micro-simulation of the study area transport network. This furthers the understanding of current transport modal distributions, factors affecting the travel mode choice decisions, and, network performance through a number of hypothetical travel scenarios.

The Evaluation Of Software Quality, Dhananjay Gade

Industrial and Management Systems Engineering -- Dissertations and Student Research

Software Quality comprises all characteristics and significant features of a product or an activity which relate to the satisfaction of given requirements. The totality of characteristics of a software product depends upon its ability to satisfy given needs: for example (a) the degree to which software possesses a desired attribute or combination of attributes. (b) The degree to which a customer or user perceives that software meets their expectations, (c) the characteristics of software that determine the degree to which the software in use will meet the customer expectation. This study has three objectives. The first objective is to identify ...

Given the choice, are there certain online approaches that engineering technology management graduate students prefer? Qualitative and quantitative data ...

A New Versatile Electronic Speckle Pattern Interferometer For Vibration Measurements, Viswanath Bavigadda (Thesis)

Doctoral

Electronic speckle pattern interferometry (ESPI) has been widely used for vibration amplitude and phase measurements. Conventional ESPI systems are bulk and expensive and need careful alignment of all the optical components which is a time consuming task. To overcome these problems alternative compact ESPI systems were developed using fibre-optical components or holographic optical elements (HOEs). The fibre-optic based ESPI systems suffer from random phase fluctuations induced by environmental temperature changes. Hence HOEs can be used as more powerful alternative optical elements to design ESPI systems. The time average ESPI method is widely used for vibration studies. The time average method ...

Techno-Economic Feasibility Study Of Ammonia Plants Powered By Offshore Wind, Eric R. Morgan

Open Access Dissertations

Ammonia production with offshore wind power has the potential to transform energy and fertilizer markets within the United States. The vast offshore wind resource can be converted directly into liquid ammonia using existing technologies. The liquid ammonia can then be transported around the country via rail, truck, barge or pipeline and used as either a fertilizer or a fuel. This thesis reviews the technologies required for all-electric, wind-powered ammonia production and offers a simple design of such a system. Cost models based on the physical equipment necessary to produce ammonia with wind power are developed; offshore wind farm cost models ...

For this purpose a new algorithm called the look ahead algorithm has been created and tested. The look ahead algorithm is applicable under limited and unlimited stacking height conditions. The look ahead algorithm is compared to the existing algorithms in the literature. The experimental results show that the look ahead algorithm ...

The Modeling, Analysis And Control Of Resilient Manufacturing Enterprises, Yao Hu

Theses and Dissertations--Electrical and Computer Engineering

The resilience of manufacturing enterprises is an important research topic, since disruptions have severe effects on the normal operation of manufacturing enterprises, especially as manufacturing supply chains become global. Although many case studies have been carried out to address resilience in organizations, a systematic method to model and analyze the resilience dynamics in manufacturing enterprises is not well developed. This study is intended to conduct research on quantitative analysis and control for resilience.

After reviewing the literature addressing resilience, a modeling framework is presented to characterize the resilience of a manufacturing enterprise responding to disruptive events, which includes inventory ow ...

Emerging Capability Or Continuous Challenge? Relocating Knowledge Work And Managing Process Interfaces, Stephan Manning, Thomas Hutzschenreuter, Alexander Strathmann

Management and Marketing Faculty Publication Series

This study examines interface management as a dynamic organizational capability supporting an increasing global distribution of knowledge work, based on an in-depth case of an automotive supplier. We show how local responses to experiences of task and interface ambiguity following the relocation of R&D processes may lead to a shift of organizational attention from ex-ante process design to continuous process and interface management. Findings suggest that flexible interface manager positions and partnership structures across locations facilitate local experimentation with effective transfer and handling of ambiguous and partially tacit tasks. This enhances the firm’s capacity to distribute an increasing ...

Global population aging is creating an immense pressure on healthcare facilities making them unable to cope with the growing demand for elderly healthcare services. Current demand-supply gaps result in prolonged waiting times for patients and substantial cost burdens for healthcare systems due to delayed discharges. This paper describes a project aimed at presenting modeling and simulation to address elderly care pathways within the Irish healthcare sector. The management of frail patients admitted to acute hospitals and the introduction of the new intermediate care beds are alternative interventions that healthcare executives are interested in simulating to examine their impact on the ...

A Simulation-Based Decision Support System To Model Complex Demand Driven Heathcare Facilities, Amr Arisha, Michael Thorwarth

Conference papers

Simulating healthcare processes is a sophisticated endeavor. Treatment processes and patient arrival patterns differ significantly in their statistical attributes and implicate a high degree of variability. In addition, there are several types of interconnected processes of medical staff involved that accompany a patient’s journey through the healthcare facility. Replicating this behavior with process flow models in a discrete event simulation model is highly complex and therefore difficult to create while maintaining a high degree of precision. A framework is thus introduced which delivers an algorithm that allows to implement Multiple Participant Pathway Modeling (MPPM) under the consideration of Flexible ...
