Intern experience at CH���M Hill, Inc.: an internship report
No full textIncludes 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
Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing 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

Distribution. High elevations in the central and northern Sierra Nevada of California. Habitat. Mixed conifer woodland. Taken from understory tangles and leaf litter in coniferous forest, under logs, in a small shrub in an open field, and from riverbanks. One male paratype sang from 2.4 m above ground in thicket of branches. He dropped to the ground when approached (JAC pers. obs.). Seasonal occurrence. Midsummer through fall, from July (1-VII-1950, HL McKenzie, CSCA) through November (17-XI-1967, HR Ingham, CSCA). Nymphs occur from early June through August, thus overlapping broadly with adult activity. Stridulatory file. (n = 6) length 3.3–3.9 mm, 115–135 teeth, tooth density 35.4 ± 3.4 (30.8–40.9) teeth/mm. Song. (n = 19) PTR is significantly faster than all other Convexa Clade lineages (ANCOVA, P = 1.08×10 -5), owing to significantly shorter MPTL of 202.5 ± 53.6 ms (ANCOVA, P = 4.27×10 -11). MPT often have a characteristic amplitude modulation pattern, with a gradual increase in amplitude followed by an abrupt increase at the middle of the PT (Plate 4F). Males may sing in the late afternoon as well as at night. Karyotype. (n = 7) 2n♁ = 26 (2m + 22t + XtYt), T88-8, S88-60, paratype. Recognition. The male ventral sclerite has straight, thick shaft, the apex rounded with the highest point lateral to the central axis, and the short lateral process directed 45 o anterior to plane of shaft. This genital morphology may only be confused with N. diabolica and some N. carinata, both of which have higher stridulatory file tooth densities and lisping songs and are distributed in the South Coast Ranges. The female subgenital plate is distinct from all other Carinata Group species: wider than long with a strongly bifurcate apex. The song PTR is faster and MPTL shorter than all other Convexa Clade taxa. This species is the only Neduba found in high elevation yellow pine forest in the central and northern Sierra Nevada Mountains of California. Etymology. l. radicata having roots, having found a home. Notes. At China Flat Campground, El Dorado County, California, two males were observed emerging from leaf litter to sing in understory tangles.Acoustical activity commenced before dusk at this locality during overcast conditions after a rainstorm. At the southern extent of the range along Finning Mill Road, males were singing before sunset at 2019 h. This species is sympatric with N. radocantans (Sierranus Group) in El Dorado County, California. Specimens examined.
