Relations of non-specific motor abilities and performances of floor exercise in artistic gymnastics
No full textIn a relatively short athletic career of women gymnasts, multilateral development of motor abilities, with the aim of quality performance of complex skills, is crucial to win a competition. Out of the four apparatuses of women’s gymnastics All Around Event, the floor exercise is, in energy terms, the most demanding. Comparatively, this study raises the question which motor abilities are required for more efficient performance of the floor exercise. The research was carried out on 26 female competitors of the Croatian “C” national program from the South region, aged 6-8 years, cadet competition category. Some of their non specific motor abilities have been analyzed by standing long jump, 20 m dash, straight arm hang, sit-ups, arm plate tapping, obstacle course backwards and sit and reach test. By regression analysis, significant impact of the standing long jump (B=-0.63; p=0.01), obstacle course backwards (B=-0.57; p=0.02) and sit and reach test (B=0.42; p=0.02) on the floor exercise performance was determined. Significant differences were determined by ANOVA in the sit-ups (F=0.0.38; p=0.02), arm plate tapping (F=0.86; p=0.02) and obstacle course backwards test (F=-0.73; p=0.01) between more efficient and less efficient competitors. In accordance with the demands put upon the competitors by the analyzed exercise, but also by the Code of Point, the obtained results are considered logical
Olympic games (Beijing) analysis: the performance key
No full textDespite the fact that they predominantly qualified as All-Around competitors for the Olympic Games in Beijing (OG2012), only about 61% of gymnasts competed All-Around in the Qualifying competition (C-I), while others competed on some or only on one apparatus. The smallest percentage of gymnasts competed the vault (70%); the apparatus on which the lowest value of Difficulty Score (DS=5.35), the highest value of the Execution Score (ES=8.43) and finally the highest Final Score (FS=14.03) were determined, as compared to other apparatuses. Approximately 82% competitors competed in Uneven Bars, Balance Beam and Floor. Although these were the world's best gymnasts, significant differences were determined in almost all DS, ES and FS (of all apparatuses) between differently ranked All-Around competitors of the C-I competition at the OG2012. These results are probably the consequence of tactics, but also the objectives of different gymnasts related to the results at the Olympic Games. The selection of appropriate tactics is the key in extending relatively short career of elite female gymnasts

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

Selected components of physical fitness in rhythmic and artistic youth gymnast
No full textPurpose: Rhythmic (RG) and artistic gymnastics (AG) are very popular female sports. These two disciplines share some common points but, at the same time, they display some relevant differences in terms of physical and technical characteristics. The aim of this study was as follows: (1) to clarify how gymnastic training background over the years could lead to the development and motor learning of the motor skills and (2) to highlight differences of conditional skills achieved by RG and AG athletes. Methods: For these aims, 45 athletes were selected, belonging to three balanced groups: promotional (PG, n = 15), RG (n = 15), and AG (n = 15). Participants were tested for joints mobility, balance, explosive strength, speed, and endurance tests. Results: Statistical analysis showed a good test–retest reliability of the measurements (ICC > 0.870) and some significant differences between PG, RG, and AG. RG showed higher values in joint mobility tests (coxo-femoral mobility, 166.7 ± 6.3°; sit and reach, 20.5 ± 1.9 cm; and scapulo-humeral mobility, 45.5 ± 4.4 cm) with respect to AG, while AG showed higher values in endurance (1626.7 ± 7.4 m), balance (4.33 ± 1.35 n/60 s), and explosive strength (164.1 ± 11.6 cm) compared to RG (p < 0.05). Conclusion: RG and AG seem to be effective in enhancing different and sport-specific physical fitness and conditioning. RG enables, indeed, to develop more joints mobility whereas AG improves more strength, balance, and endurance. However, given the small sample size employed, these results should be replicated by further studies utilizing larger samples
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

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
