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

Atmospheric Shower Fluctuations And The Constant Intensity Cut Method
No full textWe explore the constant intensity cut method that is widely used for the derivation of the cosmic ray energy spectrum, for comparisons of data obtained at different atmospheric depths, for measuring average shower profiles, and for estimates of the proton-air cross section from extensive air shower data. The constant intensity cut method is based on the selection of air showers by charged particle or muon size and therefore is subject to intrinsic shower fluctuations. We demonstrate that, depending on the selection method, shower fluctuations can strongly influence the characteristics of the selected showers. Furthermore, a mixture of different primaries in the cosmic ray flux complicates the interpretation of measurements based on the method of constant intensity cuts. As an example we consider data published by the Akeno Collaboration. The interpretation of the Akeno measurements suggests that more than 60-70% of cosmic ray primaries in the energy range 10 16 - 10 17 eV are heavy nuclei. Our conclusions depend only weakly on the hadronic interaction model chosen to perform the simulations, namely SIBYLL and QGSJET. © 2002 The American Physical Society.6612J. Alvarez-Muñiz et al.

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
Face Recognition for Cognitive Robots
No full textIn the near future the elderly population will increase in size up to a point that there are not enough people to provide support. One solution would be developing service robots, that can perform household tasks and in that way allow elderly to live longer independently. These service robots have to be able to adapt to changing environments, which requires a flexible framework that can recognize and learn objects regardless of the environment or the robot architecture. In this thesis such a framework, consisting of localization, description, classification and learning modules structured as a pipeline is introduced. Various types of objects require different methods to be used in each of the modules. For efficient memory usage these methods are dynamically loaded into the pipeline in the introduced framework. For human-robot interaction users have to be robustly identified and learned online. Exist-ing state of the art methods for face recognition, such as K-Nearest Neighbours (KNN) and Principal Component Analysis (PCA), do not support online learning of faces and lack the recognition performance required to be used in real-world situations. Hence the Class Average Principal Component Analysis (CAPCA) method is developed in this thesis as a descriptor. This method provides the required performance by increasing the separability of the classes by maximizing the inter-class and minimizing intra-class variations. The speed is increased significantly by selecting only the most representative samples. Additionally to allow for classification of unknown faces, the novel Certainty K-Nearest Neighbours (CertKNN) method has been introduced. The main benefit over the state of the art methods is finding the relation between the distance of classification and the certainty of that classification. This relation is automatically calculated from the data belonging to each class. In that way nearly optimal unknown classification can be done. Finally to further improve recognition performance a method has been developed that utilizes multiple frames in classification. To prove the benefits of the introduced methods extensive experiments have been performed on a state of the art face recognition database. The best performance was achieved with a F-measure of 96% and 90% for respectively known and unknown classification. Training speed was increased up to 100 times, which allows for online learning of faces. Lastly the introduced methods were applied on the Delft Robotics service robot and extensively tested in the RoboCup@Home challenge.BMDBioMechanical EngineeringMechanical, Maritime and Materials Engineerin
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
