Intern experience at the Texas Transportation Institute: an internship report
Get PDF"Submitted to the College of Engineering of Texas A&M University in partial
fulfillment of the requirements for the degree of Doctor of Engineering."Includes vita (leaf 91)Includes bibliographical references (leaf 57)This report discusses the author's engineering experience at the Texas
Transportation Institute (TTI), Texas A&M University from March 1974 through July 1977. A
report of this experience plus twelve additional hours of academic course work were
substituted for an internship according to requirements established by the College of
Engineering. Although the author could not retroactively establish objectives of the type
associated with a typical internship, the work experience gained could be related to the two
general objectives of an intership: 1. To demonstrate an identifiable contribution to the
organization in which the intern served, and 2. To enable the intern to become aware of the
non-technical aspects of working as an engineer in a non-academic environment. While a member
of the Texas Transportation Institute staff, the author worked on a number of projects in the
areas of highway traffic engineering research and the preparation of continuing education
courses for transportation engineering officials. These assignments were contained within the
Urban Transportation Systems Division of TTI. This report delineates the author's contribution
to four particular projects and discusses the technical as well as non-technical experience
gained from each. Having been exposed to more engineering situations than many of the other
Doctor of Engineering students, the author has already formulated some rather specific
milestones for the future. The Doctor of Engineering program is discussed in conjunction with
its potential for helping the author attain these career goals and objectives. Also, some
thoughts are presented regarding the Doctor of Engineering as a viable alternative to the
Ph.D. in preparing for a career in engineering higher education
Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
Get PDFFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
A distribution study of deep-sea macrobenthos collected from the western Gulf of Mexico
No full textVita.One of Texas A&M University's more detailed oceanographic cruises was that of R/V ALAMINOS 69A11, basically biological in scope but also including hydrographic, sediment coring, and bottom photography stations. Dredge sampling of the deep-sea macrobenthos was accomplished by means of the benthic skimmer in three western Gulf regions (Galveston, Tampico, and Vera Cruz). This distribution study of the benthic macrofauna revealed five faunal zones that were differentiated on a bathymetric basis. These have been designated as Outer Continental Shelf, Upper Continental Slope, Lower Continental Slope, Continental Rise, and Abyssal Plain. Faunal breaks revealed by the similarity dendrogram, constructed from individual station data, support the proposed faunal zones. Recurrent patterns of species occurrence were used to formulate benthic assemblage, showing expected species and their relative abundance, for specific depths within the faunal zones. Data concerning species occurrence within the three geographic regions of the western Gulf under consideration were not sufficient to warrant extension of existing biotic provinces into the deep sea. Analysis of sea-floor photographs revealed at least 87 living organisms, various plant fragments, sediment composition and texture, and other ichnological phenomena. Several selected photographs have been included. A phylogenetic list of all benthic species, including author and date, collected as living specimens at one or more of the dredge stations has been compiled. Slight modification and combination of the suprageneric taxonomy used by earlier authors was utilized
Intern experience at CH���M Hill, Inc.: an internship report
Get PDFIncludes author's vita"Submitted to the College of Engineering of Texas A&M University in partial
fulfillment of the requirement for the degree of Doctor of Engineering."Includes bibliographical referencesA review of the author's internship experience with CH���M HILL, Inc.
during the period September 1975 through May 1976 is presented. During this nine month
internship the author worked as an Engineer II in the Industrial Processes discipline of this
large consulting engineering firm... The author's prime responsibility was as one of three
lead design engineers on the design of a large wastewater treatment facility for a pulp mill
in Hoquiam, Washington owned by ITT Rayonier Inc. The work generally consisted of the design
of individual treatment units and associated piping and pumping. The purpose of the project
was to provide wastewater treatment capabilities that would satisfy the effluent limitations
(standards) imposed upon the mill by the State of Washington Department of Ecology and the
U.S. Environmental Protection Agency. The author's assignment also entailed necessary
interaction with the project manager and other CH���M HILL design engineers and support staff
members, the client's representatives, and representatives of two other consulting engineering
firms working on the project. Thus, the internship position at CH���M HILL provided considerable
experience coordinating the author's work with the work of other engineers, guiding the design
and administrative efforts of a support staff, and interacting regularly with the client and
other consulting firms. This broad exposure to a variety of engineering and organizational
problems provided a valuable educational experience

A principal in transition: an autoethnography
Get PDFThis research represents a highly personalized account of the complexities,
interpretations, and reflections of a principal in transition from one elementary school to
another elementary school in the same district. Using myself as the subject and the
researcher in the social context of an elementary school provided the impetus for this
self-study. Through an insider's vantage point, I have chronicled and traced the
experiences of my own administrative transition using the qualitative methodology of
autoethnography. This genre of qualitative research brings the reader closer to the
subculture studied through the experiences of the author. While every campus and
district has its own unique culture and environment, the introspection and evaluation
provided by the methodology of autoethnography greatly facilitates an understanding of
the processes of transition. The experiences I have encountered, the problems I face, and
the interpretations derived from them will strengthen my own practice as a public school
administrator and provide insight into the ever-changing administrative position called
the principalship. Data gathering consisted of a reflexive journal, my personal calendar, faculty
agendas, staff memos, and reflective analysis. At the completion of the school year
common strands, key attributes, and coding of the data served to provide retrospective
insights. These research tools were used to capture the experiences of my administrative
transition.
The results of this study were expressed in a personal narrative that comprises
Chapters IV through VI. Chapters I through III present a traditional dissertation model
that includes the introduction, review of literature, and research methodology. Chapter
VII offers recommendations, a discussion of the findings and concluding remarks
Industrial Energy Efficiency as a Risk Management Strategy
No full textIndustry utilizes risk management as a tool in efforts to maximize the bottom line. Industry embraced risk management strategies in the 1960s and since then it has become a key component of a comprehensive business strategy. Peter Fusaro, author of Energy Risk Management explains, ���The risk management process reduces financial exposure associated with price volatility by substituting a transaction made now for one that would be made at a later date.��� Risk management aids companies in minimizing operational surprises or losses. In recent decades, energy has become a greater risk to profitability due to the volatility that exists in the oil and natural gas markets. Therefore, companies now consider energy as an element of their risk management portfolio. Traditional strategies to combat against unwanted exposure in this market include hedging and long term and futures contracts. However, the following explores the topic of considering energy efficiency as a risk management tool in reducing exposure to the volatility of the energy market
A frequency compensated real time DSP GMSK modem
No full textDue to the character of the original source materials and the nature of batch digitization, quality control issues may be present in this document. Please report any quality issues you encounter to [email protected], referencing the URI of the item.Includes bibliographical references: p. 52-54.Issued also on microfiche from Lange Micrographics.In low-earth-orbit (LEO) satellite applications, frequency offsets due to Doppler can be large, and can degrade significantly receiver performance. In this thesis real-time implementation trade-offs are analyzed for a GMSK modem operating under large frequency offsets, using a fast, blind frequency compensation algorithm derived recently. The GMSK modem and frequency compensation algorithm is implemented in real-time on a DSP processor
The long-wavelength view of GG Tau A: rocks in the ring world
No full textWe present the first detection of GG Tau A at centimetre wavelengths, made with the Arcminute Microkelvin Imager Large Array at a frequency of 16 GHz (λ = 1.8 cm). The source is detected at >6 σrms with an integrated flux density of S16GHz = 249 ± 45 µJy. We use these new centimetre-wave data, in conjunction with additional measurements compiled from the literature, to investigate the long-wavelength tail of the dust emission from this unusual protoplanetary system. We use an MCMC-based method to determine maximum likelihood parameters for a simple parametric spectral model and consider the opacity and mass of the dust contributing to the microwave emission. We derive a dust mass of Md ~ 0.1 Msun, constrain the dimensions of the emitting region and find that the opacity index at λ > 7 mm is less than unity, implying a contribution to the dust population from grains exceeding ~4 cm in size. We suggest that this indicates coagulation within the GG Tau A system has proceeded to the point where dust grains have grown to the size of small rocks with dimensions of a few centimetres. Considering the relatively young age of the GG Tau association in combination with the low derived disc mass, we suggest that this system may provide a useful test case for rapid core accretion planet formation models
