Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

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
Modeling a 30 GHz waveguide loaded detuned structure for the compact linear collider (CLIC)
No full textOne of the major challenges in designing a multi bunch structure for the Compact Linear Collider Study CLIC are the long range transverse wake fields, which couple the transverse motion of adjacent bu nches and lead to instabilities. To the most part, possible solutions, which suppress the long range wake, require a mechanical precision, which is difficult to achieve for the high fundamental freque ncy of 30 GHz. A possible way out of this dilemma consists of combining a loose detuning with the strong damping provided by radial waveguide loads. For this type of structure, an equivalent circuit m odel has been developed, which simulates the behavior of the total structure for the lower two dipole bands. The circuit parameters are derived from the results of numerical field calculations. Mismat ch of the waveguide loads is incorporated in the circuit model via a table of scattering parameters. Using this model, a first 'skeleton' design has been done. Requiring only a limited performance of the waveguide loads, this design shows a sufficient suppression of the transverse long range wakes
