Design, Operation, Control, and Economics of a Photovoltaic/Fuel Cell/Battery Hybrid Renewable Energy System for Automotive Applications
No full textPublisher's PDF.Meeting rapidly growing global energy demand—without producing greenhouse
gases or further diminishing the availability of non-renewable resources—requires the
development of affordable low-emission renewable energy systems. Here, we develop a
hybrid renewable energy system (HRES) for automotive applications—specifically,
a roof-installed photovoltaic (PV) array combined with a PEM fuel cell/NiCd battery bus
currently operating shuttle routes on the University of Delaware campus. The system’s
overall operating objectives—meeting the total power demand of the bus and maintaining
the desired state of charge (SOC) of the NiCd battery—are achieved with appropriately
designed controllers: a logic-based “algebraic controller” and a standard PI controller.
The design, implementation, and performance of the hybrid system are demonstrated via
simulation of real shuttle runs under various operating conditions. The results show that
both control strategies perform equally well in enabling the HRES to meet its objectives
under typical operating conditions, and under sudden cloud cover conditions; however,
at consistently high bus speeds, battery SOC maintenance is better, and the system consumes
less hydrogen, with PI control. An economic analysis of the PV investment necessary to
realize the HRES design objectives indicates a return on investment of approximately 30%
(a slight, but nonetheless positive, ~$550 profit over the bus lifetime) in Newark, DE, establishing the economic viability of the proposed addition of a PV array to the existing
University of Delaware fuel cell/battery bus.University of Delaware. Department of Chemical & Biomolecular Engineering.University of Delaware. Department of Mechanical Engineering

Aisopos: Fables Told in Type and Ornament
No full textHere is a lovely book done under the direction of Gloria Kondrup and Heidrun Mumper-Drumm. The preface by Bruce Whiteman of the William Andrews Clark Memorial Library. Hand-bound by Alice Vaughan. Unpaginated. There are thirty-three pairs of pages, the first a nearly transparent page with the name of the student who did the design of the fable itself, which is on the second, underlying page. Many of the fable texts are straightforward. Several are not. Among those apart from the tradition is the third selection by Sarah Cathcart: I am Aesop, Gabriel, a Liar. I'll build my wings with paper, glue, and wire. I'll catch an updraft in the city tonight. I gotta be ready. You don't fuck around with flight. So there! D. Reagan Marshall gets the swirls of the 2 in the title 2 Crabs to represent the sideways walking of the two crabs. Soyoung Leah Kim's title The Fox with the Cropped Tail is itself cropped on the edge of the page. Clever! Dyna Kau does lovely work with designs and colors in a version of GA called Summertime. Emily Liu works with several highly expressive designs for her version of WC. A standard feature of the pages is a rectangular section in the upper left that usually contains the text of the story. Other things like the title and moral often fall outside this rectangle. Another favorite of mine is The Scorpion and the Frog by Christine Marie Montgomery. Ellen Wong's fable is new to me and very strong. I quote it without attending to its poetic form. Cartier a richman bought his wife a Cartier necklace every month. (Just for being beautiful) he said. One day, she observed a wrinkle above her right eye and decided to go under the knife. (For sure he will reward me wth an extra diamond) she thought. But with 1 cut of inexperience her face now sits lop-sided. And her husband now sits with another. Beauty is in the eye of the beholder (of the knife). I am so delighted to have found a copy of this book!This is a hardbound book (hard cover)Limited edition of 75 copiesArt Center College of Desig

The Role of Narrative Fiction and Semi-Fiction in Organizational Studies
No full textIn this chapter, we discuss the use of narrative fiction and semi-fiction in organizational research and explore the strengths and weaknesses of these alternative approaches. We begin with an introduction reviewing the existing literature and clarifying what we mean by fiction and semi-fiction. We then present and discuss examples of fiction and semi-fiction focusing on how these approaches can be used in organizational research. We argue that fiction is more useful as a source of data and as a way of representing theory to an audience. Semi-fiction, on the other hand, provides a novel approach to the production and representation of theory. In both cases, researchers face a number of challenges, but also gain access to new and powerful techniques for developing insights into organizational topics.Organizational studies;Narrative fiction;Semi-fiction

Design, analysis, operation, and advanced control of hybrid renewable energy systems
No full textOgunnaike, Babatunde A.Because using non-renewable energy systems (e.g., coal-powered cogeneration
power plants) to generate electricity is an unsustainable, environmentally
hazardous practice, it is important to develop cost-effective and reliable renewable
energy systems, such as photovoltaics (PVs), wind turbines (WTs), and fuel cells
(FCs). Non-renewable energy systems, however, are currently less expensive than
individual renewable energy systems (IRESs). Furthermore, IRESs based on
intermittent natural resources (e.g., solar irradiance and wind) are incapable of
meeting continuous energy demands. Such shortcomings can be mitigated by
judiciously combining two or more complementary IRESs to form a hybrid renewable
energy system (HRES). Although previous research efforts focused on the design,
operation, and control of HRESs has proven useful, no prior HRES research endeavor
has taken a systematic and comprehensive approach towards establishing guidelines
by which HRESs should be designed, operated, and controlled. The overall goal of
this dissertation, therefore, is to establish the principles governing the design,
operation, and control of HRESs resulting in cost-effective and reliable energy
solutions for stationary and mobile applications.
The first empirical part of this dissertation focuses on HRES equipment
selection and sizing using an economic and feasibility analysis. We determined that
HRES components and their sizes should be rationally selected using knowledge of
component costs, availability of renewable energy resources, and expected power
demands of the application. To demonstrate this statement, we ascertained the
economically preferred and feasible renewable energy system types and sizes for a
range of average annual wind speed, average annual solar irradiance, power demand
and minimum renewable fraction. We found that under some combinations of these
variables HRESs are less expensive than IRESs and grid-supplied energy. This result
has a significant implication for renewable energy systems becoming increasingly
ubiquitous.
After HRES type and sizes are selected, it is necessary to determined how the
components are arranged and what control systems are best for coordinating the entire
system to meet a set of operating objectives (typically satisfy a power demand while
storing excess power for later use). This was demonstrated by way of a case study
involving the design, control, and economics of a University of Delaware FC/battery
bus retrofitted with a roof-installed PV array. The preferred arrangement of HRES
components is the FC in series with the battery (the FC is committed to maintaining a
desired battery state of charge (SOC) while the battery meets the majority of the bus
power demand) while the PV array is used to assist the battery in meeting the bus
power demand, with excess PV power being used to charge the battery. Simulation
results indicate that under a variety of operating conditions, a PID control strategy is
best for enabling the bus to satisfy required power demands and maintain a desired
battery SOC. An economic analysis of the PV investment necessary to realize the
HRES design objectives indicates that the investment will pay for itself in Newark,
DE, establishing the economic viability of the proposed addition of a PV array to the
existing University of Delaware FC/battery bus.
Although the performance of standard controllers for HRESs is generally
satisfactory, operating objectives can be met more reliably and efficiently when
information-rich data is used to coordinate HRES component. Two such data-driven
control paradigms were developed in separate case studies. In the first case study, we
developed and evaluated a method for reconfiguration of control loops in
decentralized control schemes using directed spectral decomposition of collected
process data. This technique was applied to a stirred mixing tank process and was
shown to improve control performance under changing operating conditions. The
second case study, which involved data-driven centralized control, establishes a
method for adaptive data-driven MPC of a PV/WT/FC/battery/electrolyzer HRES for
a single-family home using measured disturbance prediction and model adaptation.
This procedure was shown to enable the HRES to better track a power demand
setpoint, resulting in increased system reliability and efficiency.
Finally, a PV/WT/battery HRES called an OMNi-Charger, which is intended
for small-scale (~1 W) remote power applications) was experimentally validated under
varying power demand, wind speed, and solar irradiance during controlled and field
tests. The OMNi-Charger controller—a simple state controller that enacts a prespecified
control action depending on the current state or operating conditions of the
system—was shown to enable the OMNi-Charger to meet varying power demands
nearly instantaneously and consistently despite rapid and unknown fluctuations in
wind speed and solar irradiance. Although the OMNi-Charger warrants some future
investigation, the device should prove useful as a cell phone charging station or a
power source for lighted ocean buoys.University of Delaware, Department of Chemical and Biomolecular EngineeringPh.D
First you have to get outside : reflections on the ecological location of qualitative fieldwork
No full textMost methodology books do not explain how nature—or in the author’s case, heavy wet snow and swampy muskeg—can be an intrinsic part of a qualitative research design. Yet the author’s inability to make sense of the subarctic not only limited her preliminary qualitative analysis, but this lack of skill also nearly killed her. This article describes the author’s emergent belief that first-hand situated knowledge of the local ecology is an essential requirement of effective qualitative inquiry in social—ecological contexts. The author uses data from two ethnographic studies that were published in the Academy of Management Journal (2000) and Organization & Environment (2004) to illustrate this point. She discusses how the local ecology affected her qualitative research design in terms of access, type of data collected, and interpretation of local management practices. The author closes by calling for a renaturing of qualitative inquiry especially as it relates to research on sustainability
